Taler: a payment system
GNU Taler is a privacy-friendly electronic payment system targeted at end users. Our demo showcases how GNU Taler enables one-click payments on the web. The user installs a browser extension that serves as a wallet for digital cash. After withdrawing electronic cash from their bank account at our demonstrator online bank (which uses an imaginary currency called "KUDOS"), the user can proceed to spend money with our demo merchants. During the payment, no authentication is required and no personally identifiable information is transmitted.
