+Allgemeine Geschäftsbedingungen für eNetzBon 
+============================================
+
+Version vom 26.2.2024
+---------------------
+
+Diese Allgemeinen Geschäftsbedingungen gelten für alle Nutzer und Händler, die das Taler-Bezahlsystem für eNetzBon verwenden.
+
+1. Vertragspartner
+------------------
+
+Diese Allgemeinen Geschäftsbedingungen (AGB) regeln die Nutzung des Taler-Bezahlsystems (nachfolgend "Taler") zwischen Ihnen (nachfolgend "Nutzer") und Taler Operations AG ("wir", "uns").
+
+2. Produktbeschreibung
+----------------------
+
+* Um die angebotenen Dienste wahrnehmen zu können, müssen Nutzer ein Taler-Wallet (elektronische Geldbörse) als Taler-App auf ihrem Smartphone oder als Erweiterung in einem Browser auf dem PC installieren.
+* Es werden keine Daten von zahlenden Nutzern benötigt und es erfolgt auch keine Registrierung oder Kontenanlage der Nutzer. Sie können ihre Waren ohne Preisgabe ihrer Identität erwerben.
+* Die Nutzer zahlen entweder in bar an den Verein Soziale Ökonomie oder an seine Mitglieder (Händler, Verkäufer) oder überweisen von ihrem bestehenden Girokonto bei einer Schweizer Bank an das Bankkonto des Vereins Soziale Ökonomie in der Währung Schweizer Franken (CHF), um dann wertbasierte elektronische Münzen in ihre Taler-Wallets abzuheben. Sie beziehen damit digitale Wertmarken, die fachsprachlich auch Token oder elektronischen Münzen genannt werden.
+* Die elektronischen Münzen werden in der Denomination eNetzBon im Taler-Wallet angezeigt und stellen Repräsentanten der Geldwerte auf dem Verrechnungskonto des Vereins Soziale Ökonomie dar.
+
+3. Digitale Erweiterung des NetzBon mit eNetzBon
+------------------------------------------------
+
+Der Verein Soziale Ökonomie arbeitet an der Digitalisierung des NetzBon mit GNU Taler, einem digitalen Bezahlsystem, das komplett auf Freier Software und quelloffener Software (FLOSS, Free Libre and Open-Source Software) basiert und den Grundsätzen der Sozialen Ökonomie folgt.
+
+Die Taler Operations AG stellt dieses Bezahlsystem dem Verein Soziale Ökonomie zur Verfügung. Die Erweiterung von NetzBon mit eNetzBon soll die Effizienz und Wirtschaftlichkeit des NetzBon verbessern, ohne jedoch die physische Form des NetzBon in naher Zukunft abzuschaffen.
+
+4. Registrierung und Konten
+---------------------------
+
+Es werden keine Daten von zahlenden Nutzern benötigt und auch nicht erfasst. Es erfolgt auch keine Registrierung oder Kontenanlage der Nutzer. 
+
+Am eNetzBon-System teilnehmende Betriebe (Händler, Verkäufer) halten beim Verein Soziale Ökonomie interne eNetzBon-Konten, auf welche sie die ihnen übergebenen Bareinzahlungen von Nutzern (Kunden, Käufern) übertragen, damit die Nutzer dann eNetzBon in ihre persönlichen Wallets abheben können.
+
+5. Käufe und Zahlungsbedingungen
+--------------------------------
+
+* Die Nutzer können eNetzBon durch zwei Verfahren erwerben bzw. das Guthaben auf ihrem Wallet erhöhen:
+
+  * a. Per Bareinzahlung durch Nutzung der "Taler Cashier-App" in der Markthalle und in der Buchhandlung, wo ein Nutzer den abzuhebenden Betrag in CHF an das Personal bar übergeben kann und dann durch das Wallet der Betrag in CHF abgehoben und im Wallet in eNetzBon umgetauscht wird.
+  * b. Per Banküberweisung an das PostFinanz-Konto des Vereins Soziale Ökonomie. Das Wallet hilft dabei den Nutzern, den Abhebevorgang einzuleiten und gibt dazu einen Verwendungszweck an, d.h. eine mehrstellige Kombination aus Nummer und Buchstaben, die im Kontoauszug des persönlichen Girokontos des jeweiligen Nutzers als Buchungstext angezeigt wird. Mit diesem Verwendungszweck kann das Wallet den Betrag zuerst in CHF abheben und dann im Wallet in eNetzBon umtauschen.
+
+* Der Preis eines eNetzBon beträgt 1 CHF. Bitte beachten Sie, dass NetzBon nicht rückerstattbar sind, daher müssen sie ausgegeben werden.
+* In der Phase der Markteinführung von eNetzBon werden keine Transaktionskosten von Nutzern erhoben. Bei der Bezahlung mit eNetzBon fallen daher vorerst keine Transaktionsgebühren an. Diese Allgemeinen Geschäftsbedingungen erlauben jedoch die Möglichkeit zukünftiger Änderungen der Gebührenordnung.
+
+6. Nutzung der Taler-App
+------------------------
+
+Die Taler-App ermöglicht keine direkten Interaktionen, sondern dient ausschliesslich dem Bezug und der Verwendung von eNetzBon bei teilnehmenden Geschäften. Spenden sind möglich. Die Nutzer verpflichten sich, die Taler-App gemäss den geltenden Gesetzen und Vorschriften zu verwenden.
+
+Dem Nutzer ist es nur möglich, mit öffentlichen Shops zu interagieren. Mit anderen Privatpersonen kann ein Nutzer nicht interagieren.
+
+7. Verpflichtende Sicherungsmassnahmen der Nutzer
+-------------------------------------------------
+
+Die Nutzer müssen sich darüber im klaren sein, elektronisches Geld wie Bargeld zu behandeln und ebenso zu sichern, d.h. ein Backup der Wallet-Daten anzulegen.
+
+Die Nutzer der Taler-App sind daher verpflichtet, den Zugang zum digitalen Endgerät zu sichern und vor unbefugtem Zugriff zu bewahren. Sie müssen die Wallet-Daten mit einer Sicherungskopie auf einem anderen Gerät speichern. Die Exportfunktion des Wallet hilft dabei, ein Backup der Wallet-Daten anzulegen und zu speichern.
+
+Ein verlorenes Nutzergerät mit einem Wallet darauf ohne Backup der eNetzBon auf einem anderen Gerät oder Datenträger bedeutet einen Totalverlust des Gegenwerts des NetzBon-Guthabens.
+
+8. Datenschutz
+--------------
+
+Die Datenschutzrichtlinien sind in einem separaten Dokument festgelegt, das die Nutzer auch in der Taler-App finden. Der Schutz der persönlichen Daten und finanziellen Informationen hat für uns höchste Priorität.
+
+Daten der Nutzer werden nicht erhoben. Beim Bezahlen mit eNetzBon werden nur Ort, Uhrzeit und der die eNetzBon empfangende Betrieb (Händler, Verkäufer) erhoben.
+
+Die anonymisierten Daten des Kaufs und der Überweisung von NetzBon an den Betrieb werden im Falle einer Untersuchung der Finma erhoben. Dies betrifft jedoch nicht Nutzer, die mit eNetzBon zahlen, sondern die Transaktionen in NetzBon zwischen dem Verein Soziale Ökonomie und den teilnehmenden Betrieben.
+
+9. Streitbeilegung
+------------------
+
+Bei etwaigen Streitigkeiten oder Unstimmigkeiten, die aus der Nutzung von Taler, der Taler-App und eNetzBon entstehen, verpflichten sich die Parteien, zunächst eine gütliche Einigung anzustreben.
+
+Wenn keine Einigung erzielt werden kann, unterliegt die Streitbeilegung den geltenden schweizerischen Gesetzen und der Gerichtsbarkeit von Biel.
+
+10. Haftungsausschluss
+----------------------
+
+UNSER TEXTVORSCHLAG ZU DIESEM PUNKT MUSS NOCH DISKUTIERT WERDEN: Die Taler Operations AG haftet bei der Erfüllung ihrer Verpflichtungen für jedes Verschulden ihrer Mitarbeiter und der Personen, die sie zur Erfüllung ihrer Verpflichtungen hinzuzieht. Soweit die Sonderbedingungen für einzelne Geschäftsbeziehungen oder sonstige Vereinbarungen etwas Abweichendes regeln, gehen diese Regelungen vor.
+
+Hat ein Nutzer des Taler-Bezahlsystems durch schuldhaftes Verhalten - zum Beispiel durch Verletzung von Mitwirkungspflichten wie regelmässige Sicherungen und Vorsichtsmassnahmen - zur Entstehung eines Schadens beigetragen, bestimmt sich nach den Grundsätzen des Mitverschuldens, in welchem Umfang Taler Operations AG und Nutzer den Schaden zu tragen haben.
+
+11. Allgemeine Bestimmungen
+---------------------------
+
+DER TEXTVORSCHLAG VOM VEREIN SOZIALE ÖKONOMIE ZU DIESEM PUNKT MUSS NOCH DISKUTIERT WERDEN: Der Verein Soziale Ökonomie behält sich vor, bei Verletzung von Regeln oder Missbrauch, gewisse Händler-Konten zu löschen.
+
+12. Änderungen der AGB
+----------------------
+
+Die Taler Operations AG behält sich das Recht vor, diese Allgemeinen Geschäftsbedingungen (AGB) ändern zu können. Die Nutzer werden über Änderungen in der Taler-App benachrichtigt.
+
+Die fortgesetzte Nutzung der Taler-App nach Änderungen der AGB gilt als Zustimmung zu den geänderten Bedingungen.
+
+13. Datenschutzbeauftragte
+--------------------------
+
+Den Datenschutzbeauftragten des Vereins Soziale Ökonomie erreichen Sie beim Sitz des Vereins in der Klybeckstrasse 95, 4057 Basel, und per E-Mail an kontakt@sozialeoekonomie.org.
+
+Den Datenschutzbeauftragten der Taler Operations AG erreichen Sie per Post an Taler Operations AG, Höheweg 80, 2502 Biel, und über die unten genannten Kontaktmöglichkeiten.
+
+14. Kontakt
+-----------
+
+Bei Fragen oder Anliegen bezüglich dieser AGB oder der Taler-App erreichen Sie uns per Post an Taler Operations AG, Höheweg 80, 2502 Biel, und über die unten genannten Kontaktmöglichkeiten.

+Allgemeine Geschäftsbedingungen für die Nutzung von TALER
+=========================================================
+
+1. Allgemeines
+--------------
+
+1.1. Dienstleistung / Geltungsbereich
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Die Taler Operations AG (nachfolgend "**TALER AG**") ist eine Schweizer Aktiengesellschaft
+mit Sitz in Zürich.
+Die TALER bietet Privatkundinnen und -kunden (nachfolgend "**Kundin und/oder Kunde**")
+unter dem Namen "TALER” eine eigenes Bezahlungssystem an (nachfolgend "TALER”).
+Diese Allgemeinen Geschäftsbedingungen (nachfolgend "**AGB**") regeln die Benutzung von
+TALER App und die von der TALER AG über die TALER erbrachten Dienstleistungen.
+Diese AGB gelten als akzeptiert, sobald die Kundin bzw. der Kunde in der TALER App das
+Einverständnis erklärt hat.
+
+[KOMMENTAR SK]
+1. Wenn es wirklich nötig ist, für "Taler Operations AG" eine Abkürzung zu verwenden, dann
+würde "TALER AG" aus Sicht der GNU-Community den Namen von GNU Taler sehr vereinnahmen.
+Mein Vorschlag wäre noch kürzer als TALER AG und birgt keine Verwechslungsgefahr,
+Vereinnahmung oder Anmaßung: TOPS AG
+
+CG: Warum nicht einfach "TOPS" statt "TOPS AG"? AG ist auch nicht relevant.
+
+2. Bitte lasst uns Gendersprache vermeiden und statt "**Kundin und Kunde**" lieber
+"**Nutzer**" verwenden und möglichst im Plural schreiben.
+
+CG: Absolut, Gendersprache ist auslaenderfeindlich weil fuer nicht-Muttersprachler
+    deutlich schwerer. Aber besser *Kunden* statt *Nutzer* weil vmtl. Kunde ein Rechtsbegriff ist.
+
+3. **Zahlungsdienst** wäre IMHO rechtlich und sprachlich besser als "Bezahlungssystem".
+Dieser Begriff entspricht dem englischen 'payment service provider' auch nach ISO 220022.
+
+CG: OK.
+
+4. Ich würde dem Zahlungsdienst keinen "Namen" geben - vor allem nicht TALER, weil das
+sofort mit einer Währung assoziiert wird. Taler ist jedoch keine Währung, sondern ein
+Bezahlsystem, das in unserem Fall in CHF denominiertes e-Geld emittiert, genauer
+gesagt TOPS-CHF. Wenn wir dafür eine Kurzbezeichnung dafür brauchen, dann wäre
+mein Vorschlag **eCHF**.
+
+Ja, bin auch gegen die Benennung, vor allem weil es eben kein *eigenes* System ist,
+nur weil ich einen Web-Server betreibe, besitze ich ja nicht das Web ;-).
+
+5. Weitere Begriffsbestimmungen wären hier sinnvoll:
+- **Zahlungsdienst** bezeichnet die Dienstleistung der Taler Operations AG mit Sitz in
+Biel (Höheweg 80, 2502 Biel, Mitglied in der anerkannten Selbstregulierungsorganisation
+gemäss Art. 24 GwG, dem VQF - Verein zur Qualitätssicherung von Finanzdienstleistungen).
+
+CG: Nein, zu komplex. Weglassen.
+
+- **Selbstregulierung** bezeichnet die Eigenschaft der Taler Operations AG als Mitglied
+einer Selbstregulierungsorganisation wie dem VQF und Betreiberin einer
+Sandbox-Dienstleistung nach Art. 6 Abs. 2 BankV ohne gewerbsmäßige Bankeneigenschaft
+(Nichtbank).
+
+CG: Auch nicht gut.  "TOPS ist Mitglied im VQF, einer FINMA-akkreditierten
+Selbstregulierungsorganisation. TOPS wird daher nicht direkt von der FINMA
+beaufsichtigt, sondern betreibt eine Finanzdienstleisung nach Art. 6 Abs. 2
+BankV ohne gewerbsmäßige Bankeneigenschaft (Nichtbank) und somit ohne
+Kundeneinlagensicherung."
+
+- **Taler-Wallet** bezeichnet eine von Taler Operations AG bereitgestellte Software, die
+digitales Bargeld (e-Geld) verwaltet, welches der Zahlungsdienst emittiert und zur
+Zahlung an Begünstigte wieder einlöst.
+- **Nutzer** bezeichnet Inhaber von Taler-Wallets und damit Zahlende bzw. potenziell
+Zahlende.
+
+CG: "Kunden sind Inhaber von durch TOPS signierten und in CHF denominierten Wertmarken
+welche in Taler-Wallets in Eigenverantwortung gespeichert werden und mit denen Kunden
+bezahlen koennen."
+
+- **Begünstigte** bezeichnet Händler, Betriebe, Verkäufer und sonstige Empfänger von
+Überweisungen des Zahlungsdiensts.
+- **Überweisungen von Nutzern** bezeichnet die Überweisungen an den hier angebotenen
+Zahlungsdienst mit dem Ziel des Abhebens von e-Geld in ein persönliches Wallet.
+
+CG: Rest weg-kuerzen:
+
+"", die als
+Publikumseinlagen bei Nichtbanken gelten. Taler Operations AG unterliegt nicht der
+Einlagensicherung und als Nichtbank auch nicht der Bankenaufsicht. Die entgegengenommen
+Gelder werden auf einem Sammelkonto aufbewahrt, um Zahlungen zwischen den Nutzern bzw.
+zwischen Zahlenden (Käufern) und Begünstigen (Verkäufern) auszuführen."" (alles streichen)
+
+- **Überweisungen an Begünstigte** bezeichnet die Überweisungen des Zahlungsdiensts an
+Händler, Betriebe, Verkäufer und sonstige Empfänger, die IBAN-Konten an Finanzinstituten in
+der Schweiz führen müssen, um die Zahlungen ihrer Kunden über den Zahlungsdienst empfangen
+zu können.
+- **Geschäftsbeziehung** bezeichnet die Beziehung zwischen Taler Operations AG und den
+Begünstigten (Händler, Betriebe, Verkäufer und sonstige Empfänger). Sollten für über 12
+Monate keine Transaktionen an die Begünstigen erfolgen, gilt die Geschäftsbeziehung als
+beendet.
+
+CG: Taler Operations AG => TOPS (ueberall!).
+
+[KOMMENTAR SK]
+
+1.2. Zugang zu den TALER Dienstleistungen
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+TALER ist ein System, das bargeldlose Zahlungen über das TALER Zahlungssystem ermöglicht.
+TALER kann von Kundinnen und Kunden verwendet werden, um Zahlungen zwischen TALER Nutzern
+durchzuführen ("**P2P-Zahlung**") und als Zahlungsmittel im stationären Handel, an
+Automaten, online und in Apps bei autorisierten Händlern oder Dienstleistungsanbietern, die
+TALER als Zahlungsmittel akzeptieren (nachfolgend "**Händler**"), eingesetzt werden
+("**P2M-Zahlung**").
+
+CG: nein, nicht noch Haendler einfuehren, einfach bei **Beguenstigten** bleiben!
+
+Die TALER AG kann sodann die Verwendung der TALER App auch im Ausland bei Händlern zulassen,
+die an einem mit dem TALER Zahlungssystem kooperierenden ausländischen Zahlungssystem
+angeschlossen sind. Solche Transaktionen werden vom ausländischen Zahlungssystem an das
+TALER Zahlungssystem weitergeleitet (nachfolgend "**internationale Zahlung**").
+Darüber hinaus bietet die TALER AG verschiedene Mehrwertleistungen an, namentlich die
+Hinterlegung oder Aktivierung von Sichtkarten und Dienstleistungen im Bereich des
+Mobile-Marketing. Diese Mehrwertleistungen erlauben Kundinnen und Kunden u.a., Coupons,
+Stempelkarten und weitere Kampagnen in der TALER App zu erhalten und zu verwalten, Stempel
+zu sammeln und Treuegeschenke, Rabatte und Gutschriften über die TALER App einzulösen.
+
+CG: obiger Paragraph ist kompletter Unsinn, einfach komplett Streichen. Wir machen
+KEINE internationalen Zahlungen, und auch keine "Mehrwertleistungen". Einfach killen!
+
+[NETZBON-NEU]
+Der Verein Soziale Ökonomie arbeitet an der Digitalisierung des NetzBon mit GNU Taler,
+einem digitalen Bezahlsystem, das komplett auf Freier Software und quelloffener Software
+(FLOSS, Free Libre and Open-Source Software) basiert und den Grundsätzen der Sozialen
+Ökonomie folgt. Die Taler Operations AG stellt dieses Bezahlsystem dem Verein Soziale
+Ökonomie zur Verfügung. Die Erweiterung von NetzBon mit eNetzBon soll die Effizienz und
+Wirtschaftlichkeit des NetzBon verbessern, ohne jedoch die physische Form des NetzBon in
+naher Zukunft abzuschaffen.
+[NETZBON-NEU]
+
+[KOMMENTAR SK]
+- Treffender als "P2M-Zahlung" wäre m.E. "C2M-Zahlung" (Customer-to-Merchant), weil die
+Zahlenden im Normalfall keine "Peers" sind, sondern einfach nur deren Kunden. P2P-Zahlungen
+liegen hingegen definitionsgemäß auch vor, wenn Zahlende von ihrem Wallet auf das Wallet
+eines Händlers Coins übertragen (Wallet-Exchange-Wallet).
+- Müssen wir "P2M" als Begriff in den AGB unbedingt verwenden? Bitte diskutieren.
+[KOMMENTAR SK]
+
+CG: Ich sehe gar nicht, das wir ueberhaupt P2P vs. P2M/C2M-Zahlungen in den AGBs unterscheiden muessen/sollten.
+
+
+1.3. Technische Voraussetzungen
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+TALER kann "_____________________". Benötigt wird "__________________________".
+Die Nutzung der Zahlungsfunktion und der Mehrwertleistungen erfordert eine aktive
+Internetverbindung.
+
+[NETZBON-NEU]
+Um die angebotenen Dienste wahrnehmen zu können, müssen Nutzer ein Taler-Wallet
+(elektronische Geldbörse) als Taler-App auf ihrem Smartphone oder als Erweiterung in einem
+Browser auf dem PC installieren.
+[NETZBON-NEU]
+
+CG: Nutzer => Kunden
+
+[KOMMENTAR SK]
+- Mir ist nicht klar, was in die Leerzeilen kommen soll.
+
+CG: Ditto.
+
+- Der Satz darunter ist korrekt, aber "Mehrwertleistungen" ein TWINT-Begriff, den wir
+streichen sollten.
+
+CG: JA!
+
+- Ich empfehle, den Satz von NETZBON zu übernehmen, denn er erwähnt auch die
+Browser-Erweiterungen und spricht allumfassend von "Diensten".
+
+CG: Ja. Bitte noch hinzufuegen: "Kunden sind frei in der Wahl ihrer Taler-Wallet
+    Anwendung. Beguenstigte sind ebenfalls frei in der Wahl ihrer Taler-Wallet
+    Anwendung bzw. ihres Taler-Backends. Verschiedene Loesungen werden von
+    diversen Anbietern bereitgestellt.
+    TOPS macht hier keine Einschraenkungen, und uebernimmt keine Gewaehrleistung.
+    Kunden sind eigenverantwortlich fuer die Sicherheit ihrer Taler-Wallets bzw.
+    Taler-Backends und der darin gespeicherten Wertmarken bzw. Transaktionsdaten."
+[KOMMENTAR SK]
+
+1.4. Registrierung und Identifizierung
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Zur Nutzung von TALER sind die Kundinnen und Kunden verpflichtet, sich in bei TALER zu
+registrieren und die verlangten Informationen zur Verfügung zu stellen. Die TALER AG behält
+sich vor, zur Erfüllung regulatorischer Vorgaben jederzeit weitere Informationen zu
+verlangen. Die registrierte Telefonnummer wird aus Sicherheitsgründen per SMS verifiziert.
+Mit der Registration bestätigt die Kundin bzw. der Kunde, die rechtmässige Nutzerin bzw.
+Nutzer der Telefonnummer und des Smartphones zu sein.
+Bei einer Änderung der bei der Registrierung angegebenen Daten müssen diese unverzüglich in
+TALER aktualisiert werden.
+Die TALER AG behält sich vor, Registrierungsgesuche ohne Angabe von Gründen abzulehnen bzw.
+bereits erfolgte Registrationen wieder rückgängig zu machen.
+
+[NETZBON-NEU]
+Es werden keine Daten von zahlenden Nutzern benötigt und es erfolgt auch keine
+Registrierung oder Kontenanlage der Nutzer. Sie können ihre Waren ohne Preisgabe ihrer
+Identität erwerben.
+
+Am eNetzBon-System teilnehmende Betriebe (Händler, Verkäufer) halten beim Verein Soziale
+Ökonomie interne eNetzBon-Konten, auf welche sie die ihnen übergebenen Bareinzahlungen von
+Nutzern (Kunden, Käufern) übertragen, damit die Nutzer dann eNetzBon in ihre persönlichen
+Wallets abheben können. Sie benötigen diese internen eNetzBon-Konten ebenfalls für den
+Empfang von Zahlungen der Nutzer für Güter (Waren und Dienstleistungen) der Betriebe.
+
+Die Nutzer leisten Ihre Einzahlung an das Bezahlsystem entweder in bar an den Verein
+Soziale Ökonomie oder an seine Mitglieder (Händler, Verkäufer) oder überweisen von ihrem
+bestehenden Girokonto bei einer Schweizer Bank an das Bankkonto des Vereins Soziale Ökonomie
+in der Währung Schweizer Franken (CHF), um dann wertbasierte elektronische Münzen in ihre
+Taler-Wallets abzuheben. Sie beziehen damit digitale Wertmarken, die wie ein
+Gutschein oder Prepaid-Guthaben zu betrachten sind. Sie werden auch als Token
+oder Coins bezeichnet. Die elektronischen Münzen werden in der Komplementärwährung
+"eNetzBon" im Taler-Wallet angezeigt und stellen Repräsentanten der Geldwerte auf dem
+Verrechnungskonto des Vereins Soziale Ökonomie in "NetzBon" dar.
+[NETZBON-NEU]
+
+[KOMMENTAR SK]
+Statt des ersten Absatzes von 1.4.:
+Zur Nutzung des Zahlungsdiensts bei Überweisungen an **Begünstige** von über 15.000
+CHF/Jahr sind diese verpflichtet, sich in bei Taler Operations AG zu registrieren und die
+dabei verlangten Informationen zur Verfügung zu stellen. Die Taler Operations AG behält
+sich vor, zur Erfüllung regulatorischer Vorgaben jederzeit weitere Informationen zu
+verlangen.
+
+Taler Operations AG benötigt zur Registrierung der Händler deren IBAN, Adresse und
+Telefonnummer (AMLA-Akte) oder es gelten die Empfangslimiten für Händler. Zur
+Nutzung des Zahlungsdiensts gehen die Begünstigten eine Geschäftsbeziehung mit Taler
+Operations AG ein. Ab einer bestimmten Umsatzhöhe sind sie verpflichtet, sich zu
+registrieren und die verlangten Informationen zur Verfügung zu stellen.
+
+Es erfolgt keine Registrierung oder Kontenanlage der **Nutzer** bei Taler Operations AG
+oder dem Bezahlsystem bzw. Zahlungsdienst. Es werden jedoch die IBAN-Konten erfasst, von
+denen die eingehenden Überweisungen erfolgen. Die Nutzer brauchen für das Abheben in
+Taler-Wallets eine Schweizer Telefonnummer zum Empfang von TANs, die der Zahlungsdienst
+versendet. Es gelten Höchstabhebegrenzen von 5.000 CHF pro Monat bzw. 15.000 CHF pro Jahr
+für die Nutzer. Bei Zahlungen an andere Nutzer (P2P-Zahlungen) bestehen für Nutzer mit
+Wohnsitz in der Schweiz Limiten von CHF 1.000 pro Monat und CHF 5.000 pro Kalenderjahr für
+das Senden und das Empfangen von e-Geld.
+[KOMMENTAR SK]
+
+CG: Bitte allgemeiner halten, die Grenzwerte CHF sollten gar nicht explizit in
+den AGBs auftauchen!  Stattdessen: "Zur Nutzung des Zahlungsdienstes sind
+Kunden und Beguenstigte verpflichtet TOPS bei der Erfuellung regulatorischer
+Vorgaben zu unterstuetzen. Insbesondere kann TOPS Auskunft verlangen ueber die
+Identitaet von wirtschaftlich Beguenstigten.  TOPS hat das Recht und die
+Pflicht ggf. Kunden und Beguenstigte von der Nutzung des Systems
+auszuschliessen sollten diese die notwendigen Auskuenfte verweigern oder
+inkorrekte Angaben machen."
+
+
+
+1.5. Geheimhaltung
+~~~~~~~~~~~~~~~~~~
+
+Der Umstand der Geschäftsbeziehung und daraus resultierende Daten (z.B. Name, Wohnort,
+Transaktionsdaten) werden grundsätzlich vertraulich behandelt. Sie können zur Erbringung von
+Dienstleistungen soweit notwendig an den Zahlungsempfänger sowie an weitere Dritte bekannt
+gegeben werden. Die Vertraulichkeit ist sodann zur Wahrung berechtigter Interessen der TALER
+AG, aber insbesondere in folgenden Fällen, aufgehoben:
+* Wahrnehmung gesetzlicher Auskunftspflichten und Erfüllung regulatorischer Vorgaben
+* Inkasso von Forderungen der TALER AG?
+* Gerichtliche Auseinandersetzungen.
+
+[NETZBON-NEU]
+Es werden keine Daten von zahlenden Nutzern benötigt und auch nicht erfasst. Es erfolgt auch
+keine Registrierung oder Kontenanlage der Nutzer.
+[NETZBON-NEU]
+
+[KOMMENTAR SK]
+- Satz 1: Geschäftsbeziehung **mit Begünstigten**
+- Ergänzen: Satz aus NETZBON-NEU
+[KOMMENTAR SK]
+
+CG: "Personenbezogene Daten werden von TOPS nur im Rahmen der zur Erfuellung
+gesetzlicher Verpflichtungen notwendigen Umfang erhoben, verarbeitet,
+aufbewahrt oder weitergegeben. Beim Bezahlvorgang mit e-Geld werden keine
+Daten zur Identitaet vom zahlenden Nutzer erfasst."
+
+
+
+1.6. Support
+~~~~~~~~~~~~
+
+Die TALER AG stellt den Kundinnen und Kunden im Sinne eines technischen Supports über die
+TALER eine Hilfefunktion zur Verfügung. Für die Erbringung dieses Supports können von der
+TALER AG auch Dritte beigezogen werden, an welche hierfür Zugriff auf relevante Daten
+gegeben werden kann.
+
+[KOMMENTAR SK]
+Ich würde hier die Haftung für die Aktionen der Dritten einschränken. Zugriff auf relevante
+Daten hätten dritte Parteien wie z.B. Auditoren oder Behörden übrigens auch nur bei Händlern
+in Bezug auf deren Daten und Umsätze. Bitte diskutieren.
+[KOMMENTAR SK]
+
+CG: Ich wuerde nur das Deutsch korrigieren wollen:
+"TOPS stellt den Nutzern auf Anfrage technischen Support zur Verfügung.  An
+der Erbringung dieses Supports können Dritte beteiligt sein.  Diese erhalten
+hierfür Zugriff auf notwendige personenbezogene Daten zur Kommunikation mit
+den Nutzern."
+
+
+1.7. Sorgfalts- und andere Pflichten der Kundinnen und Kunden
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Beim Umgang mit TALER sind insbesondere folgende Sorgfaltspflichten durch die Kundinnen und
+Kunden einzuhalten:
+* Das Smartphone, PC, Notebook etc. ist vor unbefugter Benutzung oder Manipulation zu

+Die Nutzer müssen sich darüber im klaren sein, elektronisches Geld wie Bargeld zu
+behandeln und ebenso zu sichern, d.h. ein Backup der Wallet-Daten anzulegen. Die Nutzer der
+Taler-App sind daher verpflichtet, den Zugang zum digitalen Endgerät zu sichern und vor
+unbefugtem Zugriff zu bewahren. Sie müssen die Wallet-Daten mit einer Sicherungskopie auf
+einem anderen Gerät speichern. Die Exportfunktion des Wallet hilft dabei, ein Backup der
+Wallet-Daten anzulegen und zu speichern. Ein verlorenes Nutzergerät mit einem Wallet darauf
+ohne Backup der eNetzBon auf einem anderen Gerät oder Datenträger bedeutet einen
+Totalverlust des Gegenwerts des NetzBon-Guthabens.

+
+Die TALER AG haftet nicht für den Kundinnen und Kunden entstandene Verluste oder Schäden
+aufgrund der Verwendung von TALER, insbesondere nicht für Verluste oder Schäden:
+* aufgrund von Übermittlungsfehlern, technischen Störungen oder Defekten, Ausfällen und
+unberechtigten Zugriffen oder Eingriffen auf das Smartphone;
+* die ganz oder teilweise auf einen Verstoss der Kundinnen und Kunden gegen diese AGB
+oder anwendbare Gesetze zurückzuführen sind;
+* aufgrund einer Störung oder Fehlers von TALER oder der verwendeten Hardware;
+* aufgrund von Störungen, Unterbrechungen (inkl. für Systemwartungsarbeiten) oder

+Die Haftung der TALER AG für Folgeschäden, entgangenem Gewinn, Datenverluste ist – soweit
+gesetzlich zulässig – in jedem Fall ausgeschlossen.

+fehlerhafter oder unvollständiger Angaben der Kundin bzw. des Kunden oder der Ausführung von

+ihrer Mitarbeiter und der Personen, die sie zur Erfüllung ihrer Verpflichtungen hinzuzieht.
+Soweit die Sonderbedingungen für einzelne Geschäftsbeziehungen oder sonstige Vereinbarungen
+etwas Abweichendes regeln, gehen diese Regelungen vor.

+~~~~~~~~~~~~~~~~~~~
+
+Die Kommunikation zwischen der TALER AG und den Kundinnen und Kunden erfolgt grundsätzlich
+über die TALER. Bei Bedarf kann die TALER AG die Kundinnen und Kunden auch ausserhalb der
+TALER App kontaktieren. Eine solche Kommunikation ist nicht zwingend vertraulich oder
+sicher.

+- Ergänzen: Falls eine Kommunikation zwischen der TALER AG und den Nutzern notwendig werden
+sollte, kann diese über ein Finanzinstitut (Bank des überweisenden Girokontos der Nutzer)
+oder/und über die Taler-Apps erfolgen, sofern dies technisch möglich ist.
+[KOMMENTAR SK]
+
+CG: alles falsch. Die Kommunikation von TOPS zu Nutzern erfolgt grundsätzlich
+über Benachrichtigungen im GNU Taler Protokoll. Nutzer sind dafuer verantwortlich auf
+entsprechende Benachrichtigungen zu reagieren. TOPS hat das Recht, Transaktionen
+nicht auszufuehren bis Nutzer auf diesem Weg angeforderte rechtlich notwendige Daten
+bereitstellen.
+
+
+
+1.11. Änderung AGB
+~~~~~~~~~~~~~~~~~~
+
+Die TALER AG kann die AGB jederzeit ändern. Änderungen werden auf geeignete Weise bekannt
+gegeben. Ist die Kundin bzw. der Kunde mit den Änderungen nicht einverstanden, so kann die
+Kundin bzw. der Kunde die TALER App nicht mehr verwenden.
+
+[KOMMENTAR SK]
+Vorschlag statt des obigen Absatzes:
+Die Taler Operations AG behält sich das Recht vor, diese Allgemeinen Geschäftsbedingungen
+(AGB) ändern zu können. Die Nutzer werden über Änderungen in der Taler-App benachrichtigt.
+Die fortgesetzte Nutzung der Taler-App nach Änderungen der AGB gilt als Zustimmung zu den
+geänderten Bedingungen.
+
+Der Zahlungsdienst sendet automatisch Änderungen in den AGB und Datenschutzbestimmungen
+an die Taler-Wallets mit der Notwendigkeit der Bestätigung durch die Nutzer, nach der sie
+die Taler-App weiterverwenden können.
+[KOMMENTAR SK]

+CG: "TOPS kann die AGB jederzeit ändern. Änderungen haben nur Wirkung auf nach der
+Änderung bezogene Wertmarken. Korrekte Wallets informieren Nutzer über Änderungen
+vor dem Bezug von neuen Wertmarken.  Der Bezug von Wertmarken der TOPS nach
+Änderungen der AGB gilt als Zustimmung zu den geänderten Bedingungen."

+1.12. Vorbehalt gesetzlicher Regelungen und Beschränkung der Dienstleistungen
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Allfällige Gesetzesbestimmungen, die den Betrieb und die Benutzung von Smartphones,
+Zahlungssystemen, des Internets und sonstiger dedizierter Infrastruktur regeln, bleiben
+vorbehalten und gelten ab ihrer Inkraftsetzung auch für die vorliegenden Dienstleistungen.
+Die Benutzung der Dienstleistungen aus dem Ausland kann lokalen rechtlichen Restriktionen
+unterliegen oder unter Umständen Regeln des ausländischen Rechts verletzen. Die
+Zahlungsfunktion ist grundsätzlich auf das Hoheitsgebiet der Schweiz beschränkt und darf im
+Ausland nicht in Anspruch genommen werden. Zulässig sind aber internationale Zahlungen über
+ein mit dem TALER Zahlungssystem kooperierendes ausländisches Zahlungssystem.
+
+CG: Letzten Satz hier streichen. Nix international.
+
+Die TALER AG behält sich vor, das Angebot von TALER jederzeit und ohne vorherige Ankündigung
+zu ändern, zu beschränken oder vollständig einzustellen, insbesondere aufgrund rechtlicher
+Anforderungen, technischen Problemen, zwecks Verhinderung von Missbräuchen, auf behördliche
+Anordnung oder aus Sicherheitsgründen.
+Die TALER AG kann nach eigenem Ermessen und ohne vorherige Ankündigung die Nutzung von TALER
+für einzelne Kundinnen und Kunden einschränken oder unterbinden, Zahlungen nicht oder nur
+verzögert verarbeiten, eingehende Zahlungen zurückweisen und das Auf- und Entladen
+beschränken, insbesondere wo dies nach Auffassung der TALER AG aus rechtlichen Gründen oder
+solchen, die die Reputation betreffen, angezeigt ist, bei IT-gestützten Angriffen, bei
+Missbrauch oder bei Betrugsverdacht. Im Verlaufe der Dauer der Geschäftsbeziehung können
+Umstände eintreten, die die TALER AG verpflichten, Vermögenswerte zu sperren, die
+Geschäftsbeziehung einer zuständigen Behörde zu melden oder abzubrechen.
+Die Kundinnen und Kunden sind verpflichtet, der TALER AG auf Verlangen Auskünfte zu
+erteilen, die die TALER AG benötigt, um den gesetzlichen oder internen Abklärungs- oder
+Meldepflichten nachzukommen.
+
+CG: scheint mir vieles vorher gesagtes zu duplizieren. Ggf. oben Text streichen?
+
+1.13. Geistiges Eigentum
+~~~~~~~~~~~~~~~~~~~~~~~~
+
+Für die Dauer des Vertrages erhalten die Kundinnen und Kunden das unübertragbare, nicht
+ausschliessliche Recht zur Nutzung von TALER. Inhalt und Umfang dieses Rechts ergeben sich
+aus den vorliegenden AGB. Alle Immaterialgüterrechte verbleiben bei der TALER AG oder den
+berechtigten Dritten.
+
+[KOMMENTAR SK]
+Satz 1: Für die Dauer der **Nutzung** erhalten die Nutzer das unübertragbare, nicht
+ausschliessliche Recht zur Verwendung des Bezahlsystems. Die Vertragspartner (Händler,

+~~~~~~~~~~~~~~~~
+
+Die TALER AG verpflichtet sich hinsichtlich der Beschaffung, Bearbeitung und
+Nutzung der personenbezogenen Daten der Kundinnen und Kunden die Bestimmungen der
+schweizerischen Datenschutzgesetzgebung (insbesondere Bundesgesetz über den Datenschutz,
+DSG, und Verordnung über den Datenschutz, VDSG) einzuhalten.
+
+Alle Systemdaten werden ausschliesslich in der Schweiz gehostet.
+

+Der KYC Prozess wird durch
+einen Dienstleister übernommen, welcher verpflichtet wird, die Daten ebenfalls nach Recht
+und Gesetz von der Schweiz zu sichern.
+
+CG: KYC Prozesse werden ggf. durch Dienstleister gesteuert. Diese sind ebenfalls verpflichtet
+die Daten ebenfalls nach Recht und Gesetz der Schweiz zu sichern.
+
+Die eigentichen Daten des Kernsystems werden auf
+verschlüsselten Festplatten redundant (d.h. mit Backup) gespeichert und sind nur
+autorisiertem Personal zugänglich. Autorisiertes Personal wird von TALER AG einer
+Sicherheitsprüfung unterzogen. Das gesamte Design wurde strikt nach den Grundsätzen
+"Privacy-by-Design” und "Privacy-by-Default” umgesetzt.
+
+>>>
+Taler nutzt blinde Signaturen, damit
+TALER AG nicht lernen kann, welcher legitimierte Nutzer bei welchem Verkäufer einkauft.
+Weitere nicht-blinde digitale Signaturen werden eingesetzt, um alle Transaktionsschritte
+gegenseitig zu bestätigen und auch extern z.B. gegenüber Auditoren überprüfbar zu machen.
+Gleichzeitig werden Hashfunktionen eingesetzt, um Details, die dritte Parteien nicht lernen
+sollen, auch nicht zu exponieren. Von den Käufern werden nur so viele Daten verwendet, wie
+zum Abheben in eine virtuelle Geldbörse (Wallet) notwendig sind. Die dabei bezogenen
+Bankkonten haben bereits bankenseitig eine KYC-Prüfung der Käufer durchgeführt und kennen
+deren Namen und Adressen in Verbindung mit der Bankkontennummer (IBAN). Von den Verkäufern
+sind ebenfalls IBAN-Kontennummern bekannt. Diese können bei Bedarf zuständigen Behörden und
+Auditoren offengelegt werden

+der Webseite der TALER AG (www.TALER.ch).
+
+[NETZBON-NEU]
+Die Datenschutzrichtlinien sind in einem separaten Dokument festgelegt, das die Nutzer auch
+in der Taler-App finden. Der Schutz der persönlichen Daten und finanziellen Informationen
+hat für uns höchste Priorität. Daten der Nutzer werden nicht erhoben. Beim Bezahlen mit
+eNetzBon werden nur Ort, Uhrzeit und der die eNetzBon empfangende Betrieb (Händler,
+Verkäufer) erhoben. Die anonymisierten Daten des Kaufs und der Überweisung von NetzBon an
+den Betrieb werden im Falle einer Untersuchung der Finma erhoben. Dies betrifft jedoch nicht
+Nutzer, die mit eNetzBon zahlen, sondern die Transaktionen in NetzBon zwischen dem Verein
+Soziale Ökonomie und den teilnehmenden Betrieben.

+Soweit gesetzlich zulässig, unterstehen alle Rechtsbeziehungen zwischen den Kundinnen und
+Kunden und der TALER AG (inkl. internationalen Zahlungen) ausschliesslich dem materiellen
+schweizerischen Recht, unter Ausschluss von Kollisionsrecht und unter Ausschluss von
+Staatsverträgen.
+Unter dem Vorbehalt von entgegenstehenden, zwingenden gesetzlichen Bestimmungen ist Zürich
+ausschliesslicher Gerichtsstand und Erfüllungsort. Für Kundinnen und Kunden mit Wohnsitz
+ausserhalb der Schweiz ist Zürich sodann auch Betreibungsort.
+
+[NETZBON-NEU]
+Bei etwaigen Streitigkeiten oder Unstimmigkeiten, die aus der Nutzung von Taler, der
+Taler-App und eNetzBon entstehen, verpflichten sich die Parteien, zunächst eine gütliche
+Einigung anzustreben. Wenn keine Einigung erzielt werden kann, unterliegt die

+2.1. Limiten

+
+Die Kundinnen und Kunden können bis CHF "___________________".
+Bei Zahlungen an andere TALER Nutzer (P2P-Zahlung) bestehen für Kundinnen und Kunden mit
+Wohnsitz in der Schweiz Limiten von CHF 1‘000 pro Monat und CHF 5‘000 pro Kalenderjahr für

+zusätzliche Limite einzuführen, insbesondere aus regulatorischen sowie Sicherheitsgründen.
+
+[KOMMENTAR SK]
+Änderungsvorschlag für Satz 3:
+Die TALER AG behält sich insbesondere aus regulatorischen Gründen vor, die Limite jederzeit
+zu senken oder zu erhöhen. Die Änderung wird in aktualisierten AGB angezeigt, welche die
+Nutzer vor der weiteren Nutzung des Zahlungsdiensts zu bestätigen haben.
+[KOMMENTAR SK]
+
+CG: Das wir die AGB aendern koennen haben wir bereits gesagt, wuerde ich nicht doppeln.
+
+2.2. Aufbuchen
+~~~~~~~~~~~~~~
+
+Das TALER Wallet wird von den Kundinnen und Kunden über die hierfür "_________"vorgesehenen
+Optionen aufgeladen. Es stehen folgende Möglichkeiten zur Verfügung:
+* Zum Aufbuchen der gewünschten Währung und der Geldmenge wählt man in der
+Wallet-Anwendung den von TALER AG betriebenen Exchange, an den man die Gelder vom Girokonto
+überweist und von dem schließlich das Wallet die elektronischen Repräsentanten der
+gewünschten Geldmenge abhebt (sog. Coins)
+Die TALER AG kann weitere Aufladeoptionen einführen oder bestehende Optionen nicht mehr
+anbieten.
+Allfällige mit der Ladung verbundenen Transaktions- oder sonstigen Gebühren sind durch die
+Kundinnen und Kunden zu tragen.
+Das TALER Guthaben wird nicht verzinst. Die Kundinnen und Kunden nehmen zur Kenntnis, dass
+das Guthaben nicht von der Einlagensicherung gedeckt ist.
+Der Verarbeitungsprozess für das Aufladen bzw. Entladen des TALER Guthabens kann je nach
+Ladeoption mehrere Tage Zeit in Anspruch nehmen.
+Die Kundin bzw. der Kunde erteilt für den Fall der Einrichtung der LSV-Anbindung der TALER
+AG die Ermächtigung, einzelne Daten zwecks Bonitätsprüfung an Dritte weitergeben zu können.
+
+CG: Den letzten Satz streichen.
+
+[NETZBON-KOMMENTAR]
+Die Nutzer können eNetzBon durch zwei Verfahren erwerben bzw. das Guthaben auf ihrem Wallet
+erhöhen:
+
+a. Per Bareinzahlung durch Nutzung der "Taler Cashier-App" in der
+Markthalle und in der Buchhandlung, wo ein Nutzer den abzuhebenden Betrag in CHF an das
+Personal bar übergeben kann und dann durch das Wallet der Betrag in CHF abgehoben und im
+Wallet in eNetzBon umgetauscht wird.
+
+b. Per Banküberweisung an das PostFinanz-Konto des Vereins Soziale Ökonomie. Das Wallet
+hilft dabei den Nutzern, den Abhebevorgang einzuleiten und gibt dazu einen Verwendungszweck
+an, d.h. eine mehrstellige Kombination aus Nummer und Buchstaben, die im Kontoauszug des
+persönlichhen Girokontos des jeweiligen Nutzers als Buchungstext angezeigt wird. Mit diesem
+Verwendungszweck kann das Wallet den Betrag zuerst in CHF abheben und dann im Wallet in
+eNetzBon umtauschen.
+
+Der Preis eines eNetzBon beträgt 1 CHF. Bitte beachten Sie, dass NetzBon nicht
+rückerstattbar sind, daher müssen sie ausgegeben werden.
+
+In der Phase der Markteinführung von eNetzBon werden keine Transaktionskosten von Nutzern
+erhoben. Bei der Bezahlung mit eNetzBon fallen daher vorerst keine Transaktionsgebühren an.
+Diese Allgemeinen Geschäftsbedingungen erlauben jedoch die Möglichkeit zukünftiger
+Änderungen der Gebührenordnung.

+entsprechend ausgerüsteten Ladenkassen im Inland, Automaten, im Internet, in anderen Apps,
+durch Hinterlegung als TALER Zahlungsart bei ausgewählten Händlern, bei Mehrwertleistungen
+und an andere TALER Nutzer im Rahmen der geltenden Limiten bezahlen.

+Geldempfang führen (z.B. Ladengeschäfte, Webshops, Apps und sonstige Begünstigte).
+[KOMMENTAR SK]

+dem TALER Wallet von ihrem Smartphone aus erfolgt sind, selbst wenn diese Zahlungen ohne
+ihre Zustimmung erfolgt sind.
+
+[KOMMENTAR SK]
+Es handelt sich bei dem Guthaben auf den Wallets der Nutzer um digitales Bargeld, dessen
+Eigentümerschaft technisch nicht ermittelbar ist. Jeder Teil des Guthabens erscheint in
+Form einer Datei mit alphanumerischen Zeichenfolgen und wird beim Abheben ins Wallet blind
+signiert, wodurch der Signatar keinen Rückschluss auf den Eigentümer des eingelösten
+Guthabens ziehen kann. Ist ein Guthaben eingelöst worden, kann dieses nicht noch ein
+weiteres Mal eingelöst werden. Wer das Guthaben zuerst einlöst, hat den Wert des Guthabens
+zur Zahlung verwendet.
+[KOMMENTAR SK]
+
+CG: Smartphone ist zu einschraenkend (kann ja auch ein Browser oder CLI-wallet sein!)
+CG: KOMMENTAR SK ist zu lang. Eher was von oben zum Thema Eigenverantwortung/Eigenverwahrung

+
+
+2.6. Preise und Drittvergütungen
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Die Installation von TALER und die Nutzung der damit verbundenen Dienstleistungen sind
+grundsätzlich kostenlos.
+
+CG: Streichen. TOPS hat *nichts* mit der Installation zu tun. Die machen ggf. Dritte,
+  und da haben wir auch nichts zu zu sagen, was da die Kosten sind!
+
+Internationale Zahlungen in Fremdwährungen werden automatisch zu einem von einem Dritten
+gestellten Wechselkurs in Schweizer Franken umgerechnet. Die TALER AG kann diesen
+Wechselkurs erhöhen (sog. Mark-up) sowie eine zusätzliche Gebühr für die
+Fremdwährungstransaktion verlangen. Der Mark-up und die Gebühren fliessen alleine der TALER
+AG zu.
+
+CG: Streichen, wir machen keine Konvertierung.
+

-This directory contains the privacy policy (template) for exchange
-operators.
-
-
-Dependencies
-============
-
-Generating a new Privacy Policy requires Sphinx, LaTeX with babel
-packages for all supported languages.  On Debian, you should
-at least install:
-
-$ apt install python3-sphinx sphinx-intl texlive-lang-german texlive-lang-english latexmk texlive-latex-recommended texlive-latex-extra
-
-(NOTE: List may be incomplete.)
-
-
-Updating the Privacy Policy
-===========================
-
-The master file with the Privacy Policy is 'pp.rst'.
-
-If you make substantial changes, you MUST change the "PP_VERSION"
-in contrib/Makefile.am to the new Etag.
-
-To begin the translation into other languages after editing the master
-file, run
-
-$ make gettext
-
-to generate the master PO file. Then, run
-
-$ sphinx-intl update -p _build/locale/ -l de -l fr -l it
-
-to update the PO files for the various languages (extend the list of
-languages as necessary). The PO files for the translators are kept
-at locale/$LANG/LC_MESSAGES/pp.po for the language $LANG.
-
-Once all PO files have been updated with new translations, run
-
-$ make update-pp
-
-in the "contrib/" directory to generate all of the formats.  The
-respective make rule calls the '../update-pp.sh' script in the
-contrib/ directory, which calls the 'Makefile' in the pp/
-directory for the various supported languages and file formats
-and then moves the generated files to the target directory
-('contrib/pp/$LANG/$VERSION.$FORMAT')
-
-
-Adding a new language
-=====================
-
-To add a new language $LANG, add $LANG to "PP_LANGUAGES" in
-'contrib/Makefile.am' and run
-
-$ sphinx-intl update -p _build/gettext -l $LANG
-
-to generate the PO template.

-<h1>Privacy Policy<a class="headerlink" href="#privacy-policy" title="Permalink to this headline">¶</a></h1>
-<p>Last Updated: 11.12.2019</p>
-<p>This Privacy Policy describes the policies and procedures of Taler Systems SA
-(“we,” “our,” or “us”) pertaining to the collection, use, and disclosure of
-your information on our sites and related mobile applications and products we
-offer (the “Services” or “Taler Wallet”). This Privacy Statement applies to
-your personal data when you use our Services, and does not apply to online
-websites or services that we do not own or control.</p>
-<div class="section" id="overview">
-<h2>Overview<a class="headerlink" href="#overview" title="Permalink to this headline">¶</a></h2>
-<p>Your privacy is important to us. We follow a few fundamental principles: We
-don’t ask you for personally identifiable information (defined below). That
-being said, your contact information, such as your phone number, social media
-handle, or email address (depending on how you contact us), may be collected
-when you communicate with us, for example to report a bug or other error
-related to the Taler Wallet. We don’t share your information with third
-parties except when strictly required to deliver you our Services and
-products, or to comply with the law. If you have any questions or concerns
-about this policy, please reach out to us at <a class="reference external" href="mailto:privacy%40taler-systems.net">privacy<span>@</span>taler-systems<span>.</span>net</a>.</p>

-<h2>How you accept this policy<a class="headerlink" href="#how-you-accept-this-policy" title="Permalink to this headline">¶</a></h2>
-<p>By using our Services or visiting our sites, you agree to the use, disclosure,
-and procedures outlined in this Privacy Policy.</p>

-<h2>What personal information do we collect from our users?<a class="headerlink" href="#what-personal-information-do-we-collect-from-our-users" title="Permalink to this headline">¶</a></h2>
-<p>The information we collect from you falls into two categories: (i) personally
-identifiable information (i.e., data that could potentially identify you as an
-individual) (“Personal Information”), and (ii) non-personally identifiable
-information (i.e., information that cannot be used to identify who you are)
-(“Non-Personal Information”). This Privacy Policy covers both categories and
-will tell you how we might collect and use each type.</p>
-<p>We do our best to not collect any Personal Information from Taler Wallet
-users. We believe that the Taler Wallet never transmits personal information
-to our services without at least clear implied consent, and we only process
-and retain information with a strict business need. That being said, when
-using our Services, we inherently have to collect the following information:</p>
-<blockquote>
-<div><ul class="simple">
-<li><p>Bank account details necessary when receiving funds from you to top-up your wallet or to transfer funds to you when you are being paid via Taler. At the current experimental stage, only the pseudonym and password you entered in the bank demonstrator is stored.</p></li>
-<li><p>The amounts being withdrawn or deposited, with associated unique transaction identifiers and cryptographic signatures authorizing the transaction. Note that for purchases, we cannot identify the buyer from the collected data, so when you spend money, we only receive non-personal information.</p></li>
-<li><p>When you contact us. We may collect certain information if you choose to contact us, for example to report a bug or other error with the Taler Wallet. This may include contact information such as your name, email address or phone number depending on the method you choose to contact us.</p></li>

-Privacy Policy
-**************
-
-Last Updated: 11.12.2019
-
-This Privacy Policy describes the policies and procedures of Taler
-Systems SA (“we,” “our,” or “us”) pertaining to the collection, use,
-and disclosure of your information on our sites and related mobile
-applications and products we offer (the “Services” or “Taler Wallet”).
-This Privacy Statement applies to your personal data when you use our
-Services, and does not apply to online websites or services that we do
-not own or control.
-
-
-Overview
-========
-
-Your privacy is important to us. We follow a few fundamental
-principles: We don’t ask you for personally identifiable information
-(defined below). That being said, your contact information, such as
-your phone number, social media handle, or email address (depending on
-how you contact us), may be collected when you communicate with us,
-for example to report a bug or other error related to the Taler
-Wallet. We don’t share your information with third parties except when
-strictly required to deliver you our Services and products, or to
-comply with the law. If you have any questions or concerns about this
-policy, please reach out to us at privacy@taler-systems.net.
-
-
-How you accept this policy
-==========================
-
-By using our Services or visiting our sites, you agree to the use,
-disclosure, and procedures outlined in this Privacy Policy.
-
-
-What personal information do we collect from our users?
-=======================================================
-
-The information we collect from you falls into two categories: (i)
-personally identifiable information (i.e., data that could potentially
-identify you as an individual) (“Personal Information”), and (ii) non-
-personally identifiable information (i.e., information that cannot be
-used to identify who you are) (“Non-Personal Information”). This
-Privacy Policy covers both categories and will tell you how we might
-collect and use each type.
-
-We do our best to not collect any Personal Information from Taler
-Wallet users. We believe that the Taler Wallet never transmits
-personal information to our services without at least clear implied
-consent, and we only process and retain information with a strict
-business need. That being said, when using our Services, we inherently
-have to collect the following information:
-
-   * Bank account details necessary when receiving funds from you to
-     top-up your wallet or to transfer funds to you when you are being
-     paid via Taler. At the current experimental stage, only the
-     pseudonym and password you entered in the bank demonstrator is
-     stored.
-
-   * The amounts being withdrawn or deposited, with associated unique
-     transaction identifiers and cryptographic signatures authorizing
-     the transaction. Note that for purchases, we cannot identify the
-     buyer from the collected data, so when you spend money, we only
-     receive non-personal information.
-
-   * When you contact us. We may collect certain information if you
-     choose to contact us, for example to report a bug or other error
-     with the Taler Wallet. This may include contact information such
-     as your name, email address or phone number depending on the
-     method you choose to contact us.
-
-
-How we collect and process information
-======================================
-
-We may process your information for the following reasons:
-
-   * to transfer money as specified by our users (Taler transactions);
-
-   * to assist government entities in linking income to the underlying
-     contract as required by law and local regulations
-
-   * to support you using the Taler Wallet or to improve our Services
-
-
-How we share and use the information we gather
-==============================================
-
-We may share your Personal Data or other information about you only if
-you are a merchant receiving income, with your bank, to the degree
-necessary to execute the payment.
-
-We retain Personal Data to transfer funds to the accounts designated
-by our users. We may retain Personal Data only for as long as mandated
-by law and required for the wire transfers.
-
-We primarily use the limited information we receive directly from you
-to enhance the Taler Wallet. Some ways we may use your Personal
-Information are to: Contact you when necessary to respond to your
-comments, answer your questions, or obtain additional information on
-issues related to bugs or errors with the Taler Wallet that you
-reported.
-
-
-Agents or third party partners
-==============================
-
-We may provide your Personal Information to our employees,
-contractors, agents, service providers, and designees (“Agents”) to
-enable them to perform certain services for us exclusively, including:
-improvement and maintenance of our software and Services.
-
-
-Protection of us and others
-===========================
-
-We reserve the right to access, read, preserve, and disclose any
-information that we reasonably believe is necessary to comply with the
-law or a court order.
-
-
-What personal information can I access or change?
-=================================================
-
-You can request access to the information we have collected from you.
-You can do this by contacting us at privacy@taler-systems.net. We will
-make sure to provide you with a copy of the data we process about you.
-To comply with your request, we may ask you to verify your identity.
-We will fulfill your request by sending your copy electronically. For
-any subsequent access request, we may charge you with an
-administrative fee. If you believe that the information we have
-collected is incorrect, you are welcome to contact us so we can update
-it and keep your data accurate. Any data that is no longer needed for
-purposes specified in the “How We Use the Information We Gather”
-section will be deleted after ninety (90) days.
-

-email: privacy@taler-systems.com
-

-your rights.
-

-==============

-retain some information that you have provided to us to maintain the
-Taler Wallet or to comply with relevant laws.
-
-
-Data security
-=============
-
-We are committed to making sure your information is protected. We
-employ several physical and electronic safeguards to keep your
-information safe, including encrypted user passwords, two factor
-verification and authentication on passwords where possible, and
-securing connections with industry standard transport layer security.
-You are also welcome to contact us using GnuPG encrypted e-mail. Even
-with all these precautions, we cannot fully guarantee against the
-access, disclosure, alteration, or deletion of data through events,
-including but not limited to hardware or software failure or
-unauthorized use. Any information that you provide to us is done so
-entirely at your own risk.
-
-
-Changes and updates to privacy policy

-
-We reserve the right to update and revise this privacy policy at any
-time. We occasionally review this Privacy Policy to make sure it
-complies with applicable laws and conforms to changes in our business.

-do so at any time. If we do revise this Privacy Policy, we will update
-the “Effective Date” at the bottom of this page so that you can tell

-collect contact information and also do not track your visits, we will
-not be able to notify you directly. However, the Taler Wallet may
-inform you about a change in the privacy policy once it detects that
-the policy has changed. Please review this Privacy Policy regularly to

-This directory contains the terms of service (template) for exchange
-operators.
-
-
-Dependencies
-============
-
-Generating new Terms of Service requires Sphinx, LaTeX with babel
-packages for all supported languages.  On Debian, you should
-at least install:
-
-$ apt install python3-sphinx sphinx-intl texlive-lang-german texlive-lang-english latexmk texlive-latex-recommended texlive-latex-extra
-
-(NOTE: List may be incomplete.)
-
-
-Updating the Terms of Service
-=============================
-
-The master file with the Terms of service is 'tos.rst'.
-
-If you make substantial changes, you MUST change the "TOS_VERSION"
-in contrib/Makefile.am to the new Etag.
-
-To begin the translation into other languages after editing the master
-file, run
-
-$ make gettext
-
-to generate the master PO file. Then, run
-
-$ sphinx-intl update -p _build/locale/ -l de -l fr -l it
-
-to update the PO files for the various languages (extend the list of
-languages as necessary). The PO files for the translators are kept
-at locale/$LANG/LC_MESSAGES/tos.po for the language $LANG.
-
-Once all PO files have been updated with new translations, run
-
-$ make update-tos
-
-in the "contrib/" directory to generate all of the formats.  The
-respective make rule calls the '../update-tos.sh' script in the
-contrib/ directory, which calls the 'Makefile' in the tos/
-directory for the various supported languages and file formats
-and then moves the generated files to the target directory
-('contrib/tos/$LANG/$VERSION.$FORMAT')
-
-
-Adding a new language
-=====================
-
-To add a new language $LANG, add $LANG to "TOS_LANGUAGES" in
-'contrib/Makefile.am' and run
-
-$ sphinx-intl update -p _build/gettext -l $LANG
-
-to generate the PO template.

-<p>Last Updated: 09.06.2022</p>
-<p>Welcome! The ICE research center of the Bern University of Applied Sciences
-in Switzerland (“we,” “our,” or “us”) provides an experimental payment service
-through our Internet presence (collectively the “Services”). Before using our
-Services, please read the Terms of Service (the “Terms” or the “Agreement”)
-carefully.</p>
-<div class="section" id="this-is-research">
-<h2>This is research<a class="headerlink" href="#this-is-research" title="Permalink to this headline">¶</a></h2>
-<p>This is a research experiment. Any funds wired to our Bitcoin address are
-considered a donation to our research group. We may use them to enable
-payments following the GNU Taler protocol, or simply keep them at our
-discretion.  The service is experimental and may also be discontinued at
-any time, in which case all remaining funds will definitively be kept by
-the research group.</p>
-</div>
-<div class="section" id="overview">
-<h2>Overview<a class="headerlink" href="#overview" title="Permalink to this headline">¶</a></h2>
-<p>This section provides a brief summary of the highlights of this
-Agreement. Please note that when you accept this Agreement, you are accepting
-all of the terms and conditions and not just this section. We and possibly
-other third parties provide Internet services which interact with the Taler
-Wallet’s self-hosted personal payment application. When using the Taler Wallet
-to interact with our Services, you are agreeing to our Terms, so please read
-carefully.</p>
-<div class="section" id="highlights">
-<h3>Highlights:<a class="headerlink" href="#highlights" title="Permalink to this headline">¶</a></h3>
-<blockquote>
-<div><ul class="simple">
-<li><p>You are responsible for keeping the data in your Taler Wallet at all times
-under your control. Any losses arising from you not being in control of
-your private information are your problem.</p></li>
-<li><p>We may transfer funds we receive from our users to any legal
-recipient to the best of our ability within the limitations of the law and
-our implementation. However, the Services offered today are highly
-experimental and the set of recipients of funds is severely restricted.
-Again, we stress this is a research experiment and technically all funds
-held by the exchange are owned by the research group of the university.</p></li>
-<li><p>For our Services, we may charge transaction fees. The specific fee structure
-is provided based on the Taler protocol and should be shown to you when you
-withdraw electronic coins using a Taler Wallet. You agree and understand
-that the Taler protocol allows for the fee structure to change.</p></li>
-<li><p>You agree to not intentionally overwhelm our systems with requests and
-follow responsible disclosure if you find security issues in our services.</p></li>
-<li><p>We cannot be held accountable for our Services not being available due to
-any circumstances. If we modify or terminate our services,
-we may give you the opportunity to recover your funds. However,
-given the experimental state of the Services today, this may not be
-possible. You are strongly advised to limit your use of the Service
-to small-scale experiments expecting total loss of all funds.</p></li>
-</ul>
-</div></blockquote>
-<p>These terms outline approved uses of our Services. The Services and these
-Terms are still at an experimental stage. If you have any questions or
-comments related to this Agreement, please send us a message to
-<a class="reference external" href="mailto:ice%40bfh.ch">ice<span>@</span>bfh<span>.</span>ch</a>. If you do not agree to this Agreement, you must not
-use our Services.</p>

-<div class="section" id="how-you-accept-this-policy">
-<h2>How you accept this policy<a class="headerlink" href="#how-you-accept-this-policy" title="Permalink to this headline">¶</a></h2>
-<p>By sending funds to us (to top-up your Taler Wallet), you acknowledge that you
-have read, understood, and agreed to these Terms. We reserve the right to
-change these Terms at any time. If you disagree with the change, we may in the
-future offer you with an easy option to recover your unspent funds. However,
-in the current experimental period you acknowledge that this feature is not
-yet available, resulting in your funds being lost unless you accept the new
-Terms. If you continue to use our Services other than to recover your unspent
-funds, your continued use of our Services following any such change will
-signify your acceptance to be bound by the then current Terms. Please check
-the effective date above to determine if there have been any changes since you
-have last reviewed these Terms.</p>
-</div>
-<div class="section" id="services">
-<h2>Services<a class="headerlink" href="#services" title="Permalink to this headline">¶</a></h2>
-<p>We will try to transfer funds that we receive from users to any legal
-recipient to the best of our ability and within the limitations of the
-law. However, the Services offered today are highly experimental and the set
-of recipients of funds is severely restricted.  The Taler Wallet can be loaded
-by exchanging fiat or cryptocurrencies against electronic coins. We are
-providing this exchange service. Once your Taler Wallet is loaded with
-electronic coins they can be spent for purchases if the seller is accepting
-Taler as a means of payment. We are not guaranteeing that any seller is
-accepting Taler at all or a particular seller.  The seller or recipient of
-deposits of electronic coins must specify the target account, as per the
-design of the Taler protocol. They are responsible for following the protocol
-and specifying the correct bank account, and are solely liable for any losses
-that may arise from specifying the wrong account. We may allow the government
-to link wire transfers to the underlying contract hash. It is the
-responsibility of recipients to preserve the full contracts and to pay
-whatever taxes and charges may be applicable. Technical issues may lead to
-situations where we are unable to make transfers at all or lead to incorrect
-transfers that cannot be reversed. We may refuse to execute transfers if the
-transfers are prohibited by a competent legal authority and we are ordered to
-do so.</p>
-<p>When using our Services, you agree to not take any action that intentionally
-imposes an unreasonable load on our infrastructure. If you find security
-problems in our Services, you agree to first report them to
-<a class="reference external" href="mailto:security%40taler-systems.com">security<span>@</span>taler-systems<span>.</span>com</a> and grant us the right to publish your report. We
-warrant that we will ourselves publicly disclose any issues reported within 3
-months, and that we will not prosecute anyone reporting security issues if
-they did not exploit the issue beyond a proof-of-concept, and followed the
-above responsible disclosure practice.</p>
-</div>
-<div class="section" id="fees">
-<h2>Fees<a class="headerlink" href="#fees" title="Permalink to this headline">¶</a></h2>
-<p>You agree to pay the fees for exchanges and withdrawals completed via the
-Taler Wallet (“Fees”) as defined by us, which we may change from time to
-time. With the exception of wire transfer fees, Taler transaction fees are set
-for any electronic coin at the time of withdrawal and fixed throughout the
-validity period of the respective electronic coin. Your wallet should obtain
-and display applicable fees when withdrawing funds. Fees for coins obtained as
-change may differ from the fees applicable to the original coin. Wire transfer
-fees that are independent from electronic coins may change annually.  You
-authorize us to charge or deduct applicable fees owed in connection with
-deposits, exchanges and withdrawals following the rules of the Taler protocol.
-We reserve the right to provide different types of rewards to users either in
-the form of discount for our Services or in any other form at our discretion
-and without prior notice to you.</p>

-<h2>Eligibility and Financial self-responsibility<a class="headerlink" href="#eligibility-and-financial-self-responsibility" title="Permalink to this headline">¶</a></h2>
-<p>To be eligible to use our Services, you must be able to form legally binding
-contracts or have the permission of your legal guardian. By using our
-Services, you represent and warrant that you meet all eligibility requirements
-that we outline in these Terms.</p>
-<p>You will be responsible for maintaining the availability, integrity and
-confidentiality of the data stored in your wallet. When you setup a Taler
-Wallet, you are strongly advised to follow the precautionary measures offered
-by the software to minimize the chances to losse access to or control over
-your Wallet data. We will not be liable for any loss or damage arising from
-your failure to comply with this paragraph.</p>

-Terms Of Service
-****************
-
-Last Updated: 09.06.2022
-
-Welcome! The ICE research center of the Bern University of Applied
-Sciences in Switzerland (“we,” “our,” or “us”) provides an
-experimental payment service through our Internet presence
-(collectively the “Services”). Before using our Services, please read
-the Terms of Service (the “Terms” or the “Agreement”) carefully.
-
-
-This is research
-================
-
-This is a research experiment. Any funds wired to our Bitcoin address
-are considered a donation to our research group. We may use them to
-enable payments following the GNU Taler protocol, or simply keep them
-at our discretion.  The service is experimental and may also be
-discontinued at any time, in which case all remaining funds will
-definitively be kept by the research group.
-
-
-Overview
-========
-
-This section provides a brief summary of the highlights of this
-Agreement. Please note that when you accept this Agreement, you are
-accepting all of the terms and conditions and not just this section.
-We and possibly other third parties provide Internet services which
-interact with the Taler Wallet’s self-hosted personal payment
-application. When using the Taler Wallet to interact with our
-Services, you are agreeing to our Terms, so please read carefully.
-
-
-Highlights:
------------
-
-   * You are responsible for keeping the data in your Taler Wallet at
-     all times under your control. Any losses arising from you not
-     being in control of your private information are your problem.
-
-   * We may transfer funds we receive from our users to any legal
-     recipient to the best of our ability within the limitations of
-     the law and our implementation. However, the Services offered
-     today are highly experimental and the set of recipients of funds
-     is severely restricted. Again, we stress this is a research
-     experiment and technically all funds held by the exchange are
-     owned by the research group of the university.
-
-   * For our Services, we may charge transaction fees. The specific
-     fee structure is provided based on the Taler protocol and should
-     be shown to you when you withdraw electronic coins using a Taler
-     Wallet. You agree and understand that the Taler protocol allows
-     for the fee structure to change.
-
-   * You agree to not intentionally overwhelm our systems with
-     requests and follow responsible disclosure if you find security
-     issues in our services.
-
-   * We cannot be held accountable for our Services not being
-     available due to any circumstances. If we modify or terminate our
-     services, we may give you the opportunity to recover your funds.
-     However, given the experimental state of the Services today, this
-     may not be possible. You are strongly advised to limit your use
-     of the Service to small-scale experiments expecting total loss of
-     all funds.
-
-These terms outline approved uses of our Services. The Services and
-these Terms are still at an experimental stage. If you have any
-questions or comments related to this Agreement, please send us a
-message to ice@bfh.ch. If you do not agree to this Agreement, you must
-not use our Services.
-
-
-How you accept this policy
-==========================
-
-By sending funds to us (to top-up your Taler Wallet), you acknowledge
-that you have read, understood, and agreed to these Terms. We reserve
-the right to change these Terms at any time. If you disagree with the
-change, we may in the future offer you with an easy option to recover
-your unspent funds. However, in the current experimental period you
-acknowledge that this feature is not yet available, resulting in your
-funds being lost unless you accept the new Terms. If you continue to
-use our Services other than to recover your unspent funds, your
-continued use of our Services following any such change will signify
-your acceptance to be bound by the then current Terms. Please check
-the effective date above to determine if there have been any changes
-since you have last reviewed these Terms.
-
-
-Services
-========
-
-We will try to transfer funds that we receive from users to any legal
-recipient to the best of our ability and within the limitations of the
-law. However, the Services offered today are highly experimental and
-the set of recipients of funds is severely restricted.  The Taler
-Wallet can be loaded by exchanging fiat or cryptocurrencies against
-electronic coins. We are providing this exchange service. Once your
-Taler Wallet is loaded with electronic coins they can be spent for
-purchases if the seller is accepting Taler as a means of payment. We
-are not guaranteeing that any seller is accepting Taler at all or a
-particular seller.  The seller or recipient of deposits of electronic
-coins must specify the target account, as per the design of the Taler
-protocol. They are responsible for following the protocol and
-specifying the correct bank account, and are solely liable for any
-losses that may arise from specifying the wrong account. We may allow
-the government to link wire transfers to the underlying contract hash.
-It is the responsibility of recipients to preserve the full contracts
-and to pay whatever taxes and charges may be applicable. Technical
-issues may lead to situations where we are unable to make transfers at
-all or lead to incorrect transfers that cannot be reversed. We may
-refuse to execute transfers if the transfers are prohibited by a
-competent legal authority and we are ordered to do so.
-
-When using our Services, you agree to not take any action that
-intentionally imposes an unreasonable load on our infrastructure. If
-you find security problems in our Services, you agree to first report
-them to security@taler-systems.com and grant us the right to publish
-your report. We warrant that we will ourselves publicly disclose any
-issues reported within 3 months, and that we will not prosecute anyone
-reporting security issues if they did not exploit the issue beyond a
-proof-of-concept, and followed the above responsible disclosure
-practice.
-
-
-Fees
-====
-
-You agree to pay the fees for exchanges and withdrawals completed via
-the Taler Wallet ("Fees") as defined by us, which we may change from
-time to time. With the exception of wire transfer fees, Taler
-transaction fees are set for any electronic coin at the time of
-withdrawal and fixed throughout the validity period of the respective
-electronic coin. Your wallet should obtain and display applicable fees
-when withdrawing funds. Fees for coins obtained as change may differ
-from the fees applicable to the original coin. Wire transfer fees that
-are independent from electronic coins may change annually.  You
-authorize us to charge or deduct applicable fees owed in connection
-with deposits, exchanges and withdrawals following the rules of the
-Taler protocol. We reserve the right to provide different types of
-rewards to users either in the form of discount for our Services or in
-any other form at our discretion and without prior notice to you.
-
-
-Eligibility and Financial self-responsibility
-=============================================
-
-To be eligible to use our Services, you must be able to form legally
-binding contracts or have the permission of your legal guardian. By
-using our Services, you represent and warrant that you meet all
-eligibility requirements that we outline in these Terms.
-
-You will be responsible for maintaining the availability, integrity
-and confidentiality of the data stored in your wallet. When you setup
-a Taler Wallet, you are strongly advised to follow the precautionary
-measures offered by the software to minimize the chances to losse
-access to or control over your Wallet data. We will not be liable for
-any loss or damage arising from your failure to comply with this
-paragraph.
-
-
-Copyrights and trademarks
-=========================
-
-The Taler Wallet is released under the terms of the GNU General Public
-License (GNU GPL). You have the right to access, use, and share the
-Taler Wallet, in modified or unmodified form. However, the GPL is a
-strong copyleft license, which means that any derivative works must be
-distributed under the same license terms as the original software. If
-you have any questions, you should review the GNU GPL’s full terms and
-conditions at https://www.gnu.org/licenses/gpl-3.0.en.html.  “Taler”
-itself is a trademark of Taler Systems SA. You are welcome to use the
-name in relation to processing payments using the Taler protocol,
-assuming your use is compatible with an official release from the GNU
-Project that is not older than two years.
-
-
-Limitation of liability & disclaimer of warranties
-==================================================
-
-You understand and agree that we have no control over, and no duty to
-take any action regarding: Failures, disruptions, errors, or delays in
-processing that you may experience while using our Services; The risk
-of failure of hardware, software, and Internet connections; The risk
-of malicious software being introduced or found in the software
-underlying the Taler Wallet; The risk that third parties may obtain
-unauthorized access to information stored within your Taler Wallet,
-including, but not limited to your Taler Wallet coins or backup

-   transactions;
-
-2. server failure or data loss;
-

-   concerning any Third Party Content contained in or accessed through
-   our Services.
-
-Any other terms, conditions, warranties, or representations associated
-with such content, are solely between you and such organizations
-and/or individuals.
-
-To the fullest extent permitted by applicable law, in no event will we
-or any of our officers, directors, representatives, agents, servants,
-counsel, employees, consultants, lawyers, and other personnel
-authorized to act, acting, or purporting to act on our behalf
-(collectively the “Taler Parties”) be liable to you under contract,
-tort, strict liability, negligence, or any other legal or equitable
-theory, for:
-
-1. any lost profits, data loss, cost of procurement of substitute
-   goods or services, or direct, indirect, incidental, special,
-   punitive, compensatory, or consequential damages of any kind
-   whatsoever resulting from:
-
-   1. your use of, or conduct in connection with, our services;
-
-   2. any unauthorized use of your wallet and/or private key due to
-      your failure to maintain the confidentiality of your wallet;
-
-   3. any interruption or cessation of transmission to or from the
-      services; or
-
-   4. any bugs, viruses, trojan horses, or the like that are found in
-      the Taler Wallet software or that may be transmitted to or
-      through our services by any third party (regardless of the
-      source of origination), or
-
-2. any direct damages.
-
-These limitations apply regardless of legal theory, whether based on
-tort, strict liability, breach of contract, breach of warranty, or any
-other legal theory, and whether or not we were advised of the
-possibility of such damages. Some jurisdictions do not allow the
-exclusion or limitation of liability for consequential or incidental
-damages, so the above limitation may not apply to you.
-
-Our services are provided "as is" and without warranty of any kind. To
-the maximum extent permitted by law, we disclaim all representations
-and warranties, express or implied, relating to the services and
-underlying software or any content on the services, whether provided
-or owned by us or by any third party, including without limitation,
-warranties of merchantability, fitness for a particular purpose,
-title, non-infringement, freedom from computer virus, and any implied
-warranties arising from course of dealing, course of performance, or
-usage in trade, all of which are expressly disclaimed. In addition, we
-do not represent or warrant that the content accessible via the
-services is accurate, complete, available, current, free of viruses or
-other harmful components, or that the results of using the services
-will meet your requirements. Some states do not allow the disclaimer
-of implied warranties, so the foregoing disclaimers may not apply to
-you. This paragraph gives you specific legal rights and you may also
-have other legal rights that vary from state to state.
-
-
-Indemnity and Time limitation on claims and Termination
-=======================================================
-
-To the extent permitted by applicable law, you agree to defend,
-indemnify, and hold harmless the Taler Parties from and against any
-and all claims, damages, obligations, losses, liabilities, costs or

-to be discontinued. It is your responsibility to ensure that the Taler
-Wallet is online at least once every three months to observe these

-                of recipients of funds is severely restricted.  The Taler Wallet can be loaded
-                by exchanging fiat or cryptocurrencies against electronic coins. We are
-                providing this exchange service. Once your Taler Wallet is loaded with
-                electronic coins they can be spent for purchases if the seller is accepting
-                Taler as a means of payment. We are not guaranteeing that any seller is
-                accepting Taler at all or a particular seller.  The seller or recipient of
-                deposits of electronic coins must specify the target account, as per the
-                design of the Taler protocol. They are responsible for following the protocol
-                and specifying the correct bank account, and are solely liable for any losses
-                that may arise from specifying the wrong account. We may allow the government
-                to link wire transfers to the underlying contract hash. It is the
-                responsibility of recipients to preserve the full contracts and to pay
-                whatever taxes and charges may be applicable. Technical issues may lead to
-                situations where we are unable to make transfers at all or lead to incorrect
-                transfers that cannot be reversed. We may refuse to execute transfers if the

-<p>Last Updated: 12.4.2019</p>
-<p>Welcome! Taler Systems SA (“we,” “our,” or “us”) provides a payment service
-through our Internet presence (collectively the “Services”). Before using our
-Services, please read the Terms of Service (the “Terms” or the “Agreement”)
-carefully.</p>
-<div class="section" id="overview">
-<h2>Overview<a class="headerlink" href="#overview" title="Permalink to this headline">¶</a></h2>
-<p>This section provides a brief summary of the highlights of this
-Agreement. Please note that when you accept this Agreement, you are accepting
-all of the terms and conditions and not just this section. We and possibly
-other third parties provide Internet services which interact with the Taler
-Wallet’s self-hosted personal payment application. When using the Taler Wallet
-to interact with our Services, you are agreeing to our Terms, so please read
-carefully.</p>
-<div class="section" id="highlights">
-<h3>Highlights:<a class="headerlink" href="#highlights" title="Permalink to this headline">¶</a></h3>
-<blockquote>
-<div><ul class="simple">
-<li><p>You are responsible for keeping the data in your Taler Wallet at all times
-under your control. Any losses arising from you not being in control of
-your private information are your problem.</p></li>
-<li><p>We will try to transfer funds we hold in escrow for our users to any legal
-recipient to the best of our ability within the limitations of the law and
-our implementation. However, the Services offered today are highly
-experimental and the set of recipients of funds is severely restricted.</p></li>
-<li><p>For our Services, we may charge transaction fees. The specific fee structure
-is provided based on the Taler protocol and should be shown to you when you
-withdraw electronic coins using a Taler Wallet. You agree and understand
-that the Taler protocol allows for the fee structure to change.</p></li>
-<li><p>You agree to not intentionally overwhelm our systems with requests and
-follow responsible disclosure if you find security issues in our services.</p></li>
-<li><p>We cannot be held accountable for our Services not being available due to
-circumstances beyond our control. If we modify or terminate our services,
-we will try to give you the opportunity to recover your funds. However,
-given the experimental state of the Services today, this may not be
-possible. You are strongly advised to limit your use of the Service
-to small-scale experiments expecting total loss of all funds.</p></li>
-</ul>
-</div></blockquote>
-<p>These terms outline approved uses of our Services. The Services and these
-Terms are still at an experimental stage. If you have any questions or
-comments related to this Agreement, please send us a message to
-<a class="reference external" href="mailto:legal%40taler-systems.com">legal<span>@</span>taler-systems<span>.</span>com</a>. If you do not agree to this Agreement, you must not
-use our Services.</p>

-<div class="section" id="how-you-accept-this-policy">
-<h2>How you accept this policy<a class="headerlink" href="#how-you-accept-this-policy" title="Permalink to this headline">¶</a></h2>
-<p>By sending funds to us (to top-up your Taler Wallet), you acknowledge that you
-have read, understood, and agreed to these Terms. We reserve the right to
-change these Terms at any time. If you disagree with the change, we may in the
-future offer you with an easy option to recover your unspent funds. However,
-in the current experimental period you acknowledge that this feature is not
-yet available, resulting in your funds being lost unless you accept the new
-Terms. If you continue to use our Services other than to recover your unspent
-funds, your continued use of our Services following any such change will
-signify your acceptance to be bound by the then current Terms. Please check
-the effective date above to determine if there have been any changes since you
-have last reviewed these Terms.</p>

-<h2>Services<a class="headerlink" href="#services" title="Permalink to this headline">¶</a></h2>
-<p>We will try to transfer funds that we hold in escrow for our users to any
-legal recipient to the best of our ability and within the limitations of the
-law and our implementation. However, the Services offered today are highly
-experimental and the set of recipients of funds is severely restricted.  The
-Taler Wallet can be loaded by exchanging fiat currencies against electronic
-coins. We are providing this exchange service. Once your Taler Wallet is
-loaded with electronic coins they can be spent for purchases if the seller is
-accepting Taler as a means of payment. We are not guaranteeing that any seller
-is accepting Taler at all or a particular seller.  The seller or recipient of
-deposits of electronic coins must specify the target account, as per the
-design of the Taler protocol. They are responsible for following the protocol
-and specifying the correct bank account, and are solely liable for any losses
-that may arise from specifying the wrong account. We will allow the government
-to link wire transfers to the underlying contract hash. It is the
-responsibility of recipients to preserve the full contracts and to pay
-whatever taxes and charges may be applicable. Technical issues may lead to
-situations where we are unable to make transfers at all or lead to incorrect
-transfers that cannot be reversed. We will only refuse to execute transfers if
-the transfers are prohibited by a competent legal authority and we are ordered
-to do so.</p>
-<p>When using our Services, you agree to not take any action that intentionally
-imposes an unreasonable load on our infrastructure. If you find security
-problems in our Services, you agree to first report them to
-<a class="reference external" href="mailto:security%40taler-systems.com">security<span>@</span>taler-systems<span>.</span>com</a> and grant us the right to publish your report. We
-warrant that we will ourselves publicly disclose any issues reported within 3
-months, and that we will not prosecute anyone reporting security issues if
-they did not exploit the issue beyond a proof-of-concept, and followed the
-above responsible disclosure practice.</p>
-</div>
-<div class="section" id="fees">
-<h2>Fees<a class="headerlink" href="#fees" title="Permalink to this headline">¶</a></h2>
-<p>You agree to pay the fees for exchanges and withdrawals completed via the
-Taler Wallet (“Fees”) as defined by us, which we may change from time to
-time. With the exception of wire transfer fees, Taler transaction fees are set
-for any electronic coin at the time of withdrawal and fixed throughout the
-validity period of the respective electronic coin. Your wallet should obtain
-and display applicable fees when withdrawing funds. Fees for coins obtained as
-change may differ from the fees applicable to the original coin. Wire transfer
-fees that are independent from electronic coins may change annually.  You
-authorize us to charge or deduct applicable fees owed in connection with
-deposits, exchanges and withdrawals following the rules of the Taler protocol.
-We reserve the right to provide different types of rewards to users either in
-the form of discount for our Services or in any other form at our discretion
-and without prior notice to you.</p>

-<h2>Eligibility and Financial self-responsibility<a class="headerlink" href="#eligibility-and-financial-self-responsibility" title="Permalink to this headline">¶</a></h2>
-<p>To be eligible to use our Services, you must be able to form legally binding
-contracts or have the permission of your legal guardian. By using our
-Services, you represent and warrant that you meet all eligibility requirements
-that we outline in these Terms.</p>
-<p>You will be responsible for maintaining the availability, integrity and
-confidentiality of the data stored in your wallet. When you setup a Taler
-Wallet, you are strongly advised to follow the precautionary measures offered
-by the software to minimize the chances to losse access to or control over
-your Wallet data. We will not be liable for any loss or damage arising from
-your failure to comply with this paragraph.</p>

-Terms Of Service
-****************
-
-Last Updated: 12.4.2019
-
-Welcome! Taler Systems SA (“we,” “our,” or “us”) provides a payment
-service through our Internet presence (collectively the “Services”).
-Before using our Services, please read the Terms of Service (the
-“Terms” or the “Agreement”) carefully.
-
-
-Overview
-========
-
-This section provides a brief summary of the highlights of this
-Agreement. Please note that when you accept this Agreement, you are
-accepting all of the terms and conditions and not just this section.
-We and possibly other third parties provide Internet services which
-interact with the Taler Wallet’s self-hosted personal payment
-application. When using the Taler Wallet to interact with our
-Services, you are agreeing to our Terms, so please read carefully.
-
-
-Highlights:
------------
-
-   * You are responsible for keeping the data in your Taler Wallet at
-     all times under your control. Any losses arising from you not
-     being in control of your private information are your problem.
-
-   * We will try to transfer funds we hold in escrow for our users to
-     any legal recipient to the best of our ability within the
-     limitations of the law and our implementation. However, the
-     Services offered today are highly experimental and the set of
-     recipients of funds is severely restricted.
-
-   * For our Services, we may charge transaction fees. The specific
-     fee structure is provided based on the Taler protocol and should
-     be shown to you when you withdraw electronic coins using a Taler
-     Wallet. You agree and understand that the Taler protocol allows
-     for the fee structure to change.
-
-   * You agree to not intentionally overwhelm our systems with
-     requests and follow responsible disclosure if you find security
-     issues in our services.
-
-   * We cannot be held accountable for our Services not being
-     available due to circumstances beyond our control. If we modify
-     or terminate our services, we will try to give you the
-     opportunity to recover your funds. However, given the
-     experimental state of the Services today, this may not be
-     possible. You are strongly advised to limit your use of the
-     Service to small-scale experiments expecting total loss of all
-     funds.
-
-These terms outline approved uses of our Services. The Services and
-these Terms are still at an experimental stage. If you have any
-questions or comments related to this Agreement, please send us a
-message to legal@taler-systems.com. If you do not agree to this
-Agreement, you must not use our Services.
-
-
-How you accept this policy
-==========================
-
-By sending funds to us (to top-up your Taler Wallet), you acknowledge
-that you have read, understood, and agreed to these Terms. We reserve
-the right to change these Terms at any time. If you disagree with the
-change, we may in the future offer you with an easy option to recover
-your unspent funds. However, in the current experimental period you
-acknowledge that this feature is not yet available, resulting in your
-funds being lost unless you accept the new Terms. If you continue to
-use our Services other than to recover your unspent funds, your
-continued use of our Services following any such change will signify
-your acceptance to be bound by the then current Terms. Please check
-the effective date above to determine if there have been any changes
-since you have last reviewed these Terms.
-
-
-Services
-========
-
-We will try to transfer funds that we hold in escrow for our users to
-any legal recipient to the best of our ability and within the
-limitations of the law and our implementation. However, the Services
-offered today are highly experimental and the set of recipients of
-funds is severely restricted.  The Taler Wallet can be loaded by
-exchanging fiat currencies against electronic coins. We are providing
-this exchange service. Once your Taler Wallet is loaded with
-electronic coins they can be spent for purchases if the seller is
-accepting Taler as a means of payment. We are not guaranteeing that
-any seller is accepting Taler at all or a particular seller.  The
-seller or recipient of deposits of electronic coins must specify the
-target account, as per the design of the Taler protocol. They are
-responsible for following the protocol and specifying the correct bank
-account, and are solely liable for any losses that may arise from
-specifying the wrong account. We will allow the government to link
-wire transfers to the underlying contract hash. It is the
-responsibility of recipients to preserve the full contracts and to pay
-whatever taxes and charges may be applicable. Technical issues may
-lead to situations where we are unable to make transfers at all or
-lead to incorrect transfers that cannot be reversed. We will only
-refuse to execute transfers if the transfers are prohibited by a
-competent legal authority and we are ordered to do so.
-
-When using our Services, you agree to not take any action that
-intentionally imposes an unreasonable load on our infrastructure. If
-you find security problems in our Services, you agree to first report
-them to security@taler-systems.com and grant us the right to publish
-your report. We warrant that we will ourselves publicly disclose any
-issues reported within 3 months, and that we will not prosecute anyone
-reporting security issues if they did not exploit the issue beyond a
-proof-of-concept, and followed the above responsible disclosure
-practice.
-
-
-Fees
-====
-
-You agree to pay the fees for exchanges and withdrawals completed via
-the Taler Wallet ("Fees") as defined by us, which we may change from
-time to time. With the exception of wire transfer fees, Taler
-transaction fees are set for any electronic coin at the time of
-withdrawal and fixed throughout the validity period of the respective
-electronic coin. Your wallet should obtain and display applicable fees
-when withdrawing funds. Fees for coins obtained as change may differ
-from the fees applicable to the original coin. Wire transfer fees that
-are independent from electronic coins may change annually.  You
-authorize us to charge or deduct applicable fees owed in connection
-with deposits, exchanges and withdrawals following the rules of the
-Taler protocol. We reserve the right to provide different types of
-rewards to users either in the form of discount for our Services or in
-any other form at our discretion and without prior notice to you.
-

-binding contracts or have the permission of your legal guardian. By
-using our Services, you represent and warrant that you meet all

-
-You will be responsible for maintaining the availability, integrity
-and confidentiality of the data stored in your wallet. When you setup
-a Taler Wallet, you are strongly advised to follow the precautionary
-measures offered by the software to minimize the chances to losse
-access to or control over your Wallet data. We will not be liable for
-any loss or damage arising from your failure to comply with this
-paragraph.

-tort, strict liability, negligence, or any other legal or equitable
-theory, for:
-
-1. any lost profits, data loss, cost of procurement of substitute

-other legal theory, and whether or not we were advised of the

-do not represent or warrant that the content accessible via the

-will meet your requirements. Some states do not allow the disclaimer
-of implied warranties, so the foregoing disclaimers may not apply to

-have other legal rights that vary from state to state.
-

-or any of our officers, directors, representatives, agents, servants,

-tort, strict liability, breach of contract, breach of warranty, or any
-other legal theory, and whether or not we were advised of the

-the subject matter hereof and supersedes any and all prior

-without limitation, any prior versions of this Agreement) and every
-nature between us. Except as provided for above, any modification to
-this Agreement must be in writing and must be signed by both parties.

-            <paragraph>By sending funds to us (to top-up your Taler Wallet), you acknowledge that you
-                have read, understood, and agreed to these Terms. We reserve the right to

-                funds, your continued use of our Services following any such change will
-                signify your acceptance to be bound by the then current Terms. Please check

-            <paragraph>We will try to transfer funds that we hold in escrow for our users to any
-                legal recipient to the best of our ability and within the limitations of the
-                law and our implementation. However, the Services offered today are highly
-                experimental and the set of recipients of funds is severely restricted.  The
-                Taler Wallet can be loaded by exchanging fiat currencies against electronic
-                coins. We are providing this exchange service. Once your Taler Wallet is
-                loaded with electronic coins they can be spent for purchases if the seller is
-                accepting Taler as a means of payment. We are not guaranteeing that any seller
-                is accepting Taler at all or a particular seller.  The seller or recipient of
-                deposits of electronic coins must specify the target account, as per the
-                design of the Taler protocol. They are responsible for following the protocol
-                and specifying the correct bank account, and are solely liable for any losses
-                that may arise from specifying the wrong account. We will allow the government
-                to link wire transfers to the underlying contract hash. It is the
-                responsibility of recipients to preserve the full contracts and to pay
-                whatever taxes and charges may be applicable. Technical issues may lead to
-                situations where we are unable to make transfers at all or lead to incorrect
-                transfers that cannot be reversed. We will only refuse to execute transfers if
-                the transfers are prohibited by a competent legal authority and we are ordered
-                to do so.</paragraph>
-            <paragraph>When using our Services, you agree to not take any action that intentionally
-                imposes an unreasonable load on our infrastructure. If you find security
-                problems in our Services, you agree to first report them to
-                <reference refuri="mailto:security@taler-systems.com">security@taler-systems.com</reference> and grant us the right to publish your report. We
-                warrant that we will ourselves publicly disclose any issues reported within 3
-                months, and that we will not prosecute anyone reporting security issues if
-                they did not exploit the issue beyond a proof-of-concept, and followed the
-                above responsible disclosure practice.</paragraph>

-                for any electronic coin at the time of withdrawal and fixed throughout the
-                validity period of the respective electronic coin. Your wallet should obtain
-                and display applicable fees when withdrawing funds. Fees for coins obtained as
-                change may differ from the fees applicable to the original coin. Wire transfer

However, the Services offered today are highly experimental and the set of recipients of funds is severely restricted.  The Taler Wallet can be loaded by exchanging fiat currencies against electronic coins. We are providing this exchange service. Once your Taler Wallet is loaded with electronic coins they can be spent for purchases if the seller is accepting Taler as a means of payment. We are not guaranteeing that any seller is accepting Taler at all or a particular seller.  The seller or recipient of deposits of electronic coins must specify the target account, as per the design of the Taler protocol. They are responsible for following the protocol and specifying the correct bank account, and are solely liable for any losses that may arise from specifying the wrong account. We will allow the government to link wire transfers to the underlying contract hash. It is the responsibility of recipients to preserve the full contracts and to pay whatever taxes and charges may be applicable. Technical issues may lead to situations where we are unable to make transfers at all or lead to incorrect transfers that cannot be reversed. We will only refuse to execute transfers if the transfers are prohibited by a competent legal authority and we are ordered to do so."

Your wallet should obtain and display applicable fees when withdrawing funds. Fees for coins obtained as change may differ from the fees applicable to the original coin. Wire transfer fees that are independent from electronic coins may change annually.

+\section{Transaktionen im Taler-Bezahlsystem}\label{sec:Transaktionen}
+
+Dieser Abschnitt stellt die Transaktionen im Taler-Bezahlsystem
+vor. Die Grafiken geben wieder, in welcher Reihenfolge die beteiligten
+Parteien interagieren. \\
+F\"ur jede einzelne Transaktion ist die automatische Ausl\"osung von
+Compliance-Prozessen durch den Taler-Exchange einstellbar.
+Die im Rahmen des jeweiligen Compliance-Prozesses erzwungenen
+Pr\"ufschritte beschreibt Abschnitt~\ref{sec:triggers}.
+
+Folgende Transaktionen kommen als Ausl\"oser f\"ur AML- und KYC-Prozesse
+in Betracht:
+\begin{description}[noitemsep]
+  \item[withdraw] Ein Nutzer hebt digitales Bargeld (e-money) in Form von
+  Taler-Coins in ein Taler-Wallet ab
+  \item[reimburse] Ein Nutzer l\"asst den Gegenwert von Taler-Coins vom
+  Taler-Exchange an das urspr\"ungliche IBAN-Bankkonto zur\"uck\"uberweisen
+  \item[pay] Ein Nutzer zahlt zugunsten eines IBAN-Bankkontos des Empf\"angers
+  \item[refund] Ein Verk\"aufer erteilt einem Zahlenden die R\"uckerstattung
+  eines Zahlbetrags
+  \item[push] Ein Nutzer sendet einen Zahlbetrag an ein anderes Taler-Wallet
+  \item[pull] Ein Nutzer stellt einem anderen Taler-Wallet eine Rechnung aus
+  und fordert eine Zahlung von diesem Wallet
+  \item[shutdown] Der Betreiber des Taler-Exchange informiert die Inhaber von
+  Coins, die diese von jenem Exchange abgehoben hatten, dass der Exchange
+  geplant eingestellt und die Gegenwerte der Coins restituiert werden
+\end{description}
+
+Die Nutzer beginnen ein gesch\"aftliches Nutzungsverh\"altnis mit
+\TALER{}, wenn sie ihre Taler-Wallets anweisen, eine Abhebung durchzuf\"uhren.
+Das Taler-Bezahlsystem verwendet jedoch keine Konten, sondern wert-basierte
+Token und explizit keine konten-basierten Geld-\"Aquivalente.
+Taler soll digitales Bargeld sein und erlaubt technisch bedingt
+kein Nachvollziehen der Transaktionen seiner Nutzer, wie es Konten mit
+Eing\"angen und Ausg\"angen von Zahlungen erm\"oglichen w\"urden.
+Es gibt daher kein ``Er\"offnen'' oder ``Schliessen'' von Konten der Nutzer.
+Die Begriffe ``opening'' und ``closing'' lassen sich deshalb auch nicht auf
+das System anwenden oder \"ubertragen. \\
+
+Die Nutzer k\"onnen
+\begin{enumerate}[noitemsep]
+\item die treuh\"andisch verwalteten Einlagen gezielt auf ein bestimmtes
+Bankkonto auszahlen lassen,
+%(siehe Abschnitt~\ref{sec:deposit})
+\item an einen Verk\"aufer zahlen,
+%(siehe Abschnitt~\ref{sec:deposit})
+\item einem anderen Empf\"anger mittels peer-to-peer-Verfahren Coins zukommen
+lassen
+%(siehe Abschnitte~\ref{sec:push} und~\ref{sec:pull})
+\item die Coins in ihrem Wallet, das verloren ging oder zerst\"ort wurde,
+durch Ablauf der G\"ultigkeit entwerten lassen (dies w\"are ebenso der Fall
+bei einer langen Zeit ohne Internet-Anbindung oder ohne Installation),
+\item den Wert der Coins im Wallet durch Zahlung von Geb\"uhren f\"ur
+die Verl\"angerung ihrer G\"ultigkeit langsam verringern lassen.
+%(siehe Abschnitt~\ref{sec:fees:coin})
+\end{enumerate}
+
+Das Taler-Bezahlsystem verwehrt den Nutzern kategorisch die Abhebung
+von h\"oheren Betr\"agen als 5.000 \CURRENCY{} pro Monat bzw. von
+mehr als 15.000 \CURRENCY{} pro Jahr. Damit wird gew\"ahrleistet,
+dass die Nutzer stets unterhalb der Grenzwerte bleiben, ab denen die
+meisten Pr\"ufschritte aufgrund regulatorischer Bestimmungen erforderlich
+werden. \TALER{} stellt dar\"uber hinaus sicher, dass die Nutzer
+ausschliesslich in \LAND{} ans\"assig sind
+(siehe Abschnitt~\ref{sec:proc:domestic}), da auf ihrer Seite ein Bankkonto
+in \LAND{} f\"ur die \"Uberweisungen an den Taler-Exchange und/oder
+eine Telefonnummer mit entsprechender Vorwahl (++41) ben\"otigt werden.
+Zus\"atzlich setzt das Taler-Wallet zu jeder Zeit eine Obergrenze
+von 5.000 \CURRENCY{} auf die Coin-Betr\"age in Summe fest, so dass es
+keine weitere Abhebung \"uber diesen Grenzwert hinaus bewirken kann.
+
+F\"ur {\bf Verk\"aufer} beginnt ein gesch\"aftliches Nutzungsverh\"altnis
+mit \TALER{}, sobald sie Geldeing\"ange auf ihren IBAN-Bankkonten erhalten,
+die als Zahlungen von Nutzern des Taler-Bezahlsystems ausgel\"ost wurden
+(siehe Abschnitt~\ref{sec:deposit}). Sollten die Summen der Eing\"ange
+5.000 \CURRENCY{} pro Monat bzw. 15.000 \CURRENCY{} pro Jahr \"ubersteigen,
+kommt es zu einer KYB-Pr\"ufung, die dem Begriff ``Er\"offnen'' eines
+Kontos entspricht und die eine aktualisierte KYB-Information sowie
+die Pr\"ufung von Sanktionslisten erfordert, sofern der Verk\"aufer
+innerhalb von 24 Monaten wenigstens einen Geldeingang erhielt.
+
+Im Gegensatz zu normalen Nutzern k\"onnen Verk\"aufer im Prinzip
+Zahlungen ohne Limit empfangen. Allerdings m\"ussen diese Transaktionen
+auch wirklich als Eing\"ange auf dem Bankkonto des Unternehmens verzeichnet
+werden (im Kontoauszug). In Abh\"angigkeit von den an das Gesch\"aftskonto
+\"uberwiesenen Betr\"agen wird der Verk\"aufer einer KYB-Pr\"ufung unterzogen
+(siehe Abschnitt~\ref{sec:KYB}). Dies gilt ebenso f\"ur
+Geldw\"asche-\"Uberpr\"ufungen (AML checks).
+
+Das Taler-Bezahlsystem transferiert lediglich Gelder auf die bestehenden
+Bankkonten der Verk\"aufer, die f\"ur ihre G\"uterleistungen Zahlungen
+der Nutzer erhalten, f\"ur die bereits bei der \"Uberweisung von deren
+Kundenkonten eine KYC-Pr\"ufung erfolgte. Daher wird unseres Erachtens
+der Betreiber eines Taler-Exchange keine Mittelherkunft verlangen bzw.
+nachweisen m\"ussen
+\footnote{Wenn Unternehmen das Taler-Bezahlsystem ihrerseits f\"ur
+Zahlungen nutzen wollen, m\"ussen sie genauso wie alle anderen Nutzer
+zuerst Geld von ihrem Bankkonto an einen Taler-Exchange \"uberweisen,
+eine KYC-Pr\"ufung absolvieren und dann ihr Wallet Coins abheben lassen.
+F\"ur die gesch\"aftlichen K\"aufer gelten ebenfalls die Limits wie
+f\"ur alle anderen Nutzer.}.

+\chapter{Regulatory Triggers} \label{chap:triggers}
+
+In this chapter we show decision diagrams for regulatory processes of the
+various core operations of the GNU Taler payment system.  In each case, the
+{\bf start} state refers to one of the interactions described in the previous
+chapter.  The payment system will then use the process to arrive at an {\bf
+  allow} decision which permits the transaction to go through, or at a {\bf
+  deny} decision which ensures that the funds are not moved.
+
+The specific {\em decisions} (in green) depend on the risk profile and the
+regulatory environment. The tables in each section list the specific values
+that are to be configured.
+
+There are five types if interactions that can trigger regulatory processes:
+
+\begin{description}
+  \item[withdraw] a customer withdraws digital cash from their {\bf bank account}
+  \item[deposit] a merchant's {\bf bank account} is designated to receive a payment in digital cash
+  \item[push] a {\bf wallet} accepts a payment from another wallet
+  \item[pull] a {\bf wallet} requests a payment from another wallet
+  \item[balance] a withdraw or P2P payment causes the balance of a {\bf wallet} to exceed a given threshold
+\end{description}
+
+We note in bold the {\bf anchor} for the regulator process. The anchor is used
+to link the interaction to an identity.  Once an identity has been established
+for a particular anchor, that link is considered established for all types of
+activities involving that anchor.  A wallet is uniquely identified in the
+system by its unique cryptographic key.  A bank account is uniquely identified
+in the system by its (RFC 8905) bank routing data (usually including BIC, IBAN
+and account owner name).
+
+The KYC and AML processes themselves are described in
+Chapter~\ref{chap:regproc}.

+
+This chapter describes the interactions between the customer, exchange and
+organizations or staff assisting with regulatory processes designed to ensure
+that customers are residents in the area of operation of the payment service
+provider, are properly identified, and do not engage in money laundering.
+
+The three main regulatory processes are:
+
+\begin{description}
+\item[domestic check] This process establishes that a user is generally
+  eligible to use the payment system.  The process checks that the user has an
+  eligible address, but stops short of establishing the user's identity.
+\item[kyc] This process establishes a user's legal identity, possibly
+  using external providers to review documents and check against blacklists.
+\item[aml] The AML process reviews suspicious payment activities for
+  money laundering. Here AML staff reviews all collected information.

+\chapter{Fees} \label{chap:fees}
+
+The business model for operating a Taler exchange is to charge transaction
+fees.  Fees are charged on certain operations by the exchange.  There are two
+types of fees, {\bf wire fees} and {\bf coin fees}.  This chapter describes
+the fee structure.
+
+Fixed, amount-independent {\bf wire fees} are charged on wire transfers using
+the core banking system.  Details on wire fees are described in
+Section~\ref{sec:fees:wire}.
+
+Coin fees are more complex, as they do not exactly follow neither the usual
+percentage of volume model of other payment systems.  Instead, coin fees are
+applied per coin, resulting in a {\em logarithmic} fee structure.  As a
+result, the effective fee {\em percentage} for tiny transactions is high (for
+example 50\% for transactions of 0.0025 CHF) while the effective fee
+percentage for large transactions is nominal (for example $\approx$ 0.05\% for
+transactions of $\approx$ 40 CHF). Details on coin fees are described in
+Section~\ref{sec:fees:coin}.
+
+Fees are configurable (and that fee types beyond those described here are
+supported by the software). Thus, the specific fees may be adjusted in the
+future based on business decisions.  However, changes to the fees are never
+retroactively applied to coins already in circulation.  Wire fees that have
+been publicly announced for a particular time period also cannot be changed.
+Finally, any change to the terms of service must also be explicitly accepted
+by the users before they withdraw additional funds.

+In the analysis of the legal requirements, it is important to differentiate
+between transactions between wallets (customer-to-customer) and transactions
+where money flows from a wallet into a bank account (customer-to-merchant) as
+these have different limits: When digital coins are used to pay at a business in
+Taler, the business never actually receives usable digital coins but instead
+the amount is always directly credited to their bank account.  Depending on
+the transacted amounts, the business will nevertheless be subject to KYB
+(Section~\ref{sec:proc:kyb}) and AML checks.
+
+{\bf Customers} begin their business relationship with us when they withdraw
+digital cash.  Taler has no accounts (this is digital cash) and thus there is
+no ``opening'' or ``closing'' of accounts for consumers.  Given digital cash,
+the customers can either (1) deposit the funds explicitly into a bank account
+(see Section~\ref{sec:deposit}), (2) pay a merchant (see
+Section~\ref{sec:pay}), (3) pay another customer using a peer-to-peer
+transfer (see Sections~\ref{sec:push} and~\ref{sec:pull}), or (4) the coins
+will expire if the wallet was lost (including offline for a long time or
 uninstalled).  Finally, if a wallet remains (occasionally) online but a user
-does simply not spend the coins will (3) diminish in value from the change
+does simply not spend the coins will (5) diminish in value from the change
 fees (see Section~\ref{sec:fees:coin}) that apply to prevent the coins from
 expiring outright.
 
+For customers, we will categorically limit of digital cash withdrawn per month
+to less than CHF 5'000 per month and less than CHF 15'000 per year, thus
+ensuring that consumers remain below the thresholds where most regulatory
+processes become applicable.  Payments between users will be limited
+to receiving less than CHF 2'500 per month and less than CHF 15'000 per year.
+We will ensure that customers are Swiss
+(see Section~\ref{sec:proc:domestic}) by requiring them to have a Swiss bank
+account and/or a Swiss phone number (+41-prefix).
+%Furthermore, the wallet will
+%impose an upper limit of CHF 5000 on its balance at any point in time.
+
+For {\bf merchants}, the Taler equivalent of ``opening'' an account and thus
+establishing an ongoing business relationship is for a business to receive
+payments (see Section~\ref{sec:pay}) exceeding CHF 5'000/month or CHF
+15'000/year.  We will consider the account ``open'' (and require up-to-date KYB
+information and check sanction lists) as long as the business has made any
+transactions within the last 24 months.
+
+As we will only transfer money into the existing bank accounts of the
+merchants to compensate them for sales made using the Taler payment system, we
+do not need to check the origin of funds for those merchants as they will only
+receive funds from us.\footnote{Should businesses want to use Taler for
+expenditures, they will need to withdraw digital coins from their bank account
+just like customers, and the limits for customers will continue to apply.}
+
+For individual {\bf transactions}, we will impose a limit of CHF
+1'000/transaction (even though our reading of the regulations would permit
+individual transactions up to CHF 15'000).
+

-# LIBGNURL_CHECK_CONFIG ([DEFAULT-ACTION], [MINIMUM-VERSION],
-#                       [ACTION-IF-YES], [ACTION-IF-NO])
-# ----------------------------------------------------------
-#      David Shaw <dshaw@jabberwocky.com>   May-09-2006
-#
-# Checks for libgnurl.  DEFAULT-ACTION is the string yes or no to
-# specify whether to default to --with-libgnurl or --without-libgnurl.
-# If not supplied, DEFAULT-ACTION is yes.  MINIMUM-VERSION is the
-# minimum version of libgnurl to accept.  Pass the version as a regular
-# version number like 7.10.1. If not supplied, any version is
-# accepted.  ACTION-IF-YES is a list of shell commands to run if
-# libgnurl was successfully found and passed the various tests.
-# ACTION-IF-NO is a list of shell commands that are run otherwise.
-# Note that using --without-libgnurl does run ACTION-IF-NO.
-#
-# This macro #defines HAVE_LIBGNURL if a working libgnurl setup is
-# found, and sets @LIBGNURL@ and @LIBGNURL_CPPFLAGS@ to the necessary
-# values.  Other useful defines are LIBGNURL_FEATURE_xxx where xxx are
-# the various features supported by libgnurl, and LIBGNURL_PROTOCOL_yyy
-# where yyy are the various protocols supported by libgnurl.  Both xxx
-# and yyy are capitalized.  See the list of AH_TEMPLATEs at the top of
-# the macro for the complete list of possible defines.  Shell
-# variables $libgnurl_feature_xxx and $libgnurl_protocol_yyy are also
-# defined to 'yes' for those features and protocols that were found.
-# Note that xxx and yyy keep the same capitalization as in the
-# gnurl-config list (e.g. it's "HTTP" and not "http").
-#
-# Users may override the detected values by doing something like:
-# LIBGNURL="-lgnurl" LIBGNURL_CPPFLAGS="-I/usr/myinclude" ./configure
-#
-# For the sake of sanity, this macro assumes that any libgnurl that is
-# found is after version 7.7.2, the first version that included the
-# gnurl-config script.  Note that it is very important for people
-# packaging binary versions of libgnurl to include this script!
-# Without gnurl-config, we can only guess what protocols are available,
-# or use gnurl_version_info to figure it out at runtime.

+### Testing
+
+The makefile offers the way to execute basic tests. Just type `make test`.
+
+By default, if valgrind is available, tests are using it. It can be disabled
+by typing `make test valgrind=no` or `NOVALGRIND=1 make test`.

+# NAME
+
+mustach - Mustache templating command line engine
+
+# SYNOPSIS
+
+*mustach* [-s|--strict] JSON TEMPLATE...
+
+# DESCRIPTION
+
+Instanciate the TEMPLATE files accordingly to the JSON file.
+
+If one of the given files is *-*, the standard input is used.
+
+Option *--strict* make mustach fail if a tag is not found.
+
+# EXAMPLE
+
+A typical Mustache template file: *temp.must*
+
+```
+Hello {{name}}
+You have just won {{value}} dollars!
+{{#in_ca}}
+Well, {{taxed_value}} dollars, after taxes.
+{{/in_ca}}
+```
+
+Given a JSON file: *inst.json*
+
+```
+{
+  "name": "Chris",
+  "value": 10000,
+  "taxed_value": 6000,
+  "in_ca": true
+}
+```
+
+Calling the command *mustach inst.json temp.must*
+will produce the following output:
+
+```
+Hello Chris
+You have just won 10000 dollars!
+Well, 6000.0 dollars, after taxes.
+```

+/* The following defines the magic code sequences which the JITter
+   spots and handles magically.  Don't look too closely at them as
+   they will rot your brain.
+
+   The assembly code sequences for all architectures is in this one
+   file.  This is because this file must be stand-alone, and we don't
+   want to have multiple files.
+
+   For VALGRIND_DO_CLIENT_REQUEST, we must ensure that the default
+   value gets put in the return slot, so that everything works when
+   this is executed not under Valgrind.  Args are passed in a memory
+   block, and so there's no intrinsic limit to the number that could
+   be passed, but it's currently five.
+   
+   The macro args are: 
+      _zzq_rlval    result lvalue
+      _zzq_default  default value (result returned when running on real CPU)
+      _zzq_request  request code
+      _zzq_arg1..5  request params
+
+   The other two macros are used to support function wrapping, and are
+   a lot simpler.  VALGRIND_GET_NR_CONTEXT returns the value of the
+   guest's NRADDR pseudo-register and whatever other information is
+   needed to safely run the call original from the wrapper: on
+   ppc64-linux, the R2 value at the divert point is also needed.  This
+   information is abstracted into a user-visible type, OrigFn.
+
+   VALGRIND_CALL_NOREDIR_* behaves the same as the following on the
+   guest, but guarantees that the branch instruction will not be
+   redirected: x86: call *%eax, amd64: call *%rax, ppc32/ppc64:
+   branch-and-link-to-r11.  VALGRIND_CALL_NOREDIR is just text, not a
+   complete inline asm, since it needs to be combined with more magic
+   inline asm stuff to be useful.

+/* This is all pretty complex.  It's so as to make stack unwinding
+   work reliably.  See bug 243270.  The basic problem is the sub and
+   add of 128 of %rsp in all of the following macros.  If gcc believes
+   the CFA is in %rsp, then unwinding may fail, because what's at the
+   CFA is not what gcc "expected" when it constructs the CFIs for the
+   places where the macros are instantiated.
+
+   But we can't just add a CFI annotation to increase the CFA offset
+   by 128, to match the sub of 128 from %rsp, because we don't know
+   whether gcc has chosen %rsp as the CFA at that point, or whether it
+   has chosen some other register (eg, %rbp).  In the latter case,
+   adding a CFI annotation to change the CFA offset is simply wrong.
+
+   So the solution is to get hold of the CFA using
+   __builtin_dwarf_cfa(), put it in a known register, and add a
+   CFI annotation to say what the register is.  We choose %rbp for
+   this (perhaps perversely), because:
+
+   (1) %rbp is already subject to unwinding.  If a new register was
+       chosen then the unwinder would have to unwind it in all stack
+       traces, which is expensive, and
+
+   (2) %rbp is already subject to precise exception updates in the
+       JIT.  If a new register was chosen, we'd have to have precise
+       exceptions for it too, which reduces performance of the
+       generated code.
+
+   However .. one extra complication.  We can't just whack the result
+   of __builtin_dwarf_cfa() into %rbp and then add %rbp to the
+   list of trashed registers at the end of the inline assembly
+   fragments; gcc won't allow %rbp to appear in that list.  Hence
+   instead we need to stash %rbp in %r15 for the duration of the asm,
+   and say that %r15 is trashed instead.  gcc seems happy to go with
+   that.
+
+   Oh .. and this all needs to be conditionalised so that it is
+   unchanged from before this commit, when compiled with older gccs
+   that don't support __builtin_dwarf_cfa.  Furthermore, since
+   this header file is freestanding, it has to be independent of
+   config.h, and so the following conditionalisation cannot depend on
+   configure time checks.
+
+   Although it's not clear from
+   'defined(__GNUC__) && defined(__GCC_HAVE_DWARF2_CFI_ASM)',
+   this expression excludes Darwin.
+   .cfi directives in Darwin assembly appear to be completely
+   different and I haven't investigated how they work.
+
+   For even more entertainment value, note we have to use the
+   completely undocumented __builtin_dwarf_cfa(), which appears to
+   really compute the CFA, whereas __builtin_frame_address(0) claims
+   to but actually doesn't.  See
+   https://bugs.kde.org/show_bug.cgi?id=243270#c47

+/* NB 9 Sept 07.  There is a nasty kludge here in all these CALL_FN_
+   macros.  In order not to trash the stack redzone, we need to drop
+   %rsp by 128 before the hidden call, and restore afterwards.  The
+   nastyness is that it is only by luck that the stack still appears
+   to be unwindable during the hidden call - since then the behaviour
+   of any routine using this macro does not match what the CFI data
+   says.  Sigh.
+
+   Why is this important?  Imagine that a wrapper has a stack
+   allocated local, and passes to the hidden call, a pointer to it.
+   Because gcc does not know about the hidden call, it may allocate
+   that local in the redzone.  Unfortunately the hidden call may then
+   trash it before it comes to use it.  So we must step clear of the
+   redzone, for the duration of the hidden call, to make it safe.
+
+   Probably the same problem afflicts the other redzone-style ABIs too
+   (ppc64-linux); but for those, the stack is
+   self describing (none of this CFI nonsense) so at least messing
+   with the stack pointer doesn't give a danger of non-unwindable
+   stack. */

+   there won't be redzones marked as unaddressable) and you definitely won't
+   get any leak detection.
+
+   The following client requests allow a custom allocator to be annotated so
+   that it can be handled accurately by Valgrind.
+
+   VALGRIND_MALLOCLIKE_BLOCK marks a region of memory as having been allocated
+   by a malloc()-like function.  For Memcheck (an illustrative case), this
+   does two things:
+
+   - It records that the block has been allocated.  This means any addresses
+     within the block mentioned in error messages will be
+     identified as belonging to the block.  It also means that if the block
+     isn't freed it will be detected by the leak checker.
+
+   - It marks the block as being addressable and undefined (if 'is_zeroed' is
+     not set), or addressable and defined (if 'is_zeroed' is set).  This
+     controls how accesses to the block by the program are handled.
+   
+   'addr' is the start of the usable block (ie. after any
+   redzone), 'sizeB' is its size.  'rzB' is the redzone size if the allocator
+   can apply redzones -- these are blocks of padding at the start and end of
+   each block.  Adding redzones is recommended as it makes it much more likely
+   Valgrind will spot block overruns.  `is_zeroed' indicates if the memory is
+   zeroed (or filled with another predictable value), as is the case for
+   calloc().
+   
+   VALGRIND_MALLOCLIKE_BLOCK should be put immediately after the point where a
+   heap block -- that will be used by the client program -- is allocated.
+   It's best to put it at the outermost level of the allocator if possible;
+   for example, if you have a function my_alloc() which calls
+   internal_alloc(), and the client request is put inside internal_alloc(),
+   stack traces relating to the heap block will contain entries for both
+   my_alloc() and internal_alloc(), which is probably not what you want.
+
+   For Memcheck users: if you use VALGRIND_MALLOCLIKE_BLOCK to carve out
+   custom blocks from within a heap block, B, that has been allocated with
+   malloc/calloc/new/etc, then block B will be *ignored* during leak-checking
+   -- the custom blocks will take precedence.
+
+   VALGRIND_FREELIKE_BLOCK is the partner to VALGRIND_MALLOCLIKE_BLOCK.  For
+   Memcheck, it does two things:
+
+   - It records that the block has been deallocated.  This assumes that the
+     block was annotated as having been allocated via
+     VALGRIND_MALLOCLIKE_BLOCK.  Otherwise, an error will be issued.
+
+   - It marks the block as being unaddressable.
+
+   VALGRIND_FREELIKE_BLOCK should be put immediately after the point where a
+   heap block is deallocated.
+
+   VALGRIND_RESIZEINPLACE_BLOCK informs a tool about reallocation. For
+   Memcheck, it does four things:
+
+   - It records that the size of a block has been changed.  This assumes that
+     the block was annotated as having been allocated via
+     VALGRIND_MALLOCLIKE_BLOCK.  Otherwise, an error will be issued.
+
+   - If the block shrunk, it marks the freed memory as being unaddressable.
+
+   - If the block grew, it marks the new area as undefined and defines a red
+     zone past the end of the new block.
+
+   - The V-bits of the overlap between the old and the new block are preserved.
+
+   VALGRIND_RESIZEINPLACE_BLOCK should be put after allocation of the new block
+   and before deallocation of the old block.
+
+   In many cases, these three client requests will not be enough to get your
+   allocator working well with Memcheck.  More specifically, if your allocator
+   writes to freed blocks in any way then a VALGRIND_MAKE_MEM_UNDEFINED call
+   will be necessary to mark the memory as addressable just before the zeroing
+   occurs, otherwise you'll get a lot of invalid write errors.  For example,
+   you'll need to do this if your allocator recycles freed blocks, but it
+   zeroes them before handing them back out (via VALGRIND_MALLOCLIKE_BLOCK).
+   Alternatively, if your allocator reuses freed blocks for allocator-internal
+   data structures, VALGRIND_MAKE_MEM_UNDEFINED calls will also be necessary.
+
+   Really, what's happening is a blurring of the lines between the client
+   program and the allocator... after VALGRIND_FREELIKE_BLOCK is called, the
+   memory should be considered unaddressable to the client program, but the
+   allocator knows more than the rest of the client program and so may be able
+   to safely access it.  Extra client requests are necessary for Valgrind to
+   understand the distinction between the allocator and the rest of the
+   program.
