Motivation

In the digital age the privacy has become an important matter. But with
the current digital payment methods the privacy of the user is not
guaranteed. To avoid the data sharing, the Taler team implemented a
digital form of cash.

Project

To demonstrate the payment system we developed an interface for a snack
machine based on GNU Taler. This implementation allows the customer to
pay with a smartphone app via NFC or QR-Code.

Team

The project was realized by Taler in cooperation with two students from
Bern University of Applied Sciences.
