the payment worked correctly within milliseconds.
Your Web customers pay with previously unknown
levels of convenience without risk of fraud.")

<h2>{{ _("Fast") }}</h2>
<p>{{ _("Processing transactions with Taler is fast,
allowing you to confirm the transaction with your
customer virtually immediately. Your customers
will appreciate that they do not have to type in
credit card information and play the "verified
by" game. By making payments significantly
more convenient for your customers, you may be able
to use Taler for small transactions that would not
work with credit card payments due to the mental
overhead for customers.") }}</p>
</div>
<div class="col-lg-4">
<h2>{{ _("Secure") }}</h2>
<p>{{ _("You will have cryptographic proof of payment from
the Taler payment service provider. Taler does not
require you to undergo any particular security
audits (such as PCI DSS), processes or procedures,
as you never handle sensitive customer account
information. Your systems will have customer
contracts wih qualified signatures for all
transactions which you can use in court in case of
disputes.") }}</p>

liberally-licensed reference code as a starting

Taler, you do not need to pay license fees, and the
free software development model will ensure that
you can select from many competent integrators for
support.") }}</p>

<h2>{{ _("Low Fees") }}</h2>

needs to perform. Combined with Taler's strong
security which prevents fraud, payment service
providers can operate with very low overhead and
thus low transaction fees.") }}</p>

Euros, US Dollars or Bitcoins) and different

supports Taler and then needs to send a
cryptographically signed version of the proposed
contract in a simple JSON format to the
customer. The message also includes salted,
hashed wire details for the merchant, as well as
restrictions as to which exchange operators the
merchant is willing to deal with.") }}</li>

states that certain digital coins now belong to
the merchant to both signal acceptance of the
deal as well as to pay the respective amount
(bottom).") }}</li>
<li>{{ _("The merchant then forwards the signed messages
received from the customer to the exchange,
together with its wire details and the salt
(without hashing). The exchange verifies the
details and sends a signed confirmation (or an
error message) to the merchant. The merchant
checks that the exchange's signature is valid,
sends a confirmation to the customer and
executes the contract-specific business
logic.") }}</li>
<li>{{ _("The exchange performs wire transfers
corresponding to the claims deposited by the
merchant. Note that the exchange may charge
fees for the deposit operation, hence merchants
may impose limits restricting the set of
exchange operators they are willing to deal
with, for example by imposing a bound on
deposit fees.") }}</li>
