Step 1: Install the Taler wallet

+ Install the wallet from the installation page. + It only takes one click. +

+ You don't have a wallet installed yet. +

+

+ Congratulations, you have installed the Taler wallet correctly. + You can now proceed with the next steps. +

+
+ +
+

Step 2: Withdraw coins

+

+ + Now you can withdraw coins into your wallet by going to our bank. + + In this demo you are paying with KUDOS, an imaginary currency. When you + create an account at our bank, you'll get 100 KUDOS for free. +

+

+ We cannnot check if you were able to complete this step, since websites + cannot see the balance in your wallet. Please click on the Taler icon + in your browser to check your balance. +

+
+ +
+

Step 3: Pay

+ We have two demo merchants where you can spend your coins: +
    +
  • + The essay store, where you can pay KUDOS for + individual chapters of Richard Stallman's book "Free Software, Free + Society", which is also available for free at the FSF. +
    • +
  • + The project donation website, where + you can show respect to a software project of your choice + by giving them KUDOS. +
    • +
+
+
+

Step 4: Check money flow

+
    +
  • + Check if people who received your Taler payment got eventually + paid by the exchange via a wire transfer; visit the: + public accounts page at the bank. + Note that only those account whose owners gave permission are showed + on that page. +
    • +
+
+ +
+

Step 5: Reach out to us

+ Let us know what you think by contacting us. +
