GNU Taler is a new electronic online payment system which provides privacy for customers and accountability for merchants. To pay with Taler, customers install an electronic wallet on their device. Before the first payment, the desired currency must be added to the wallet's balance by some other means of payment. Once the wallet is charged, payments on websites take only one click, are never falsely rejected by fraud detection and do not pose any risk of phishing or identity theft. The goal of this project is to create a component that sits between the seller's frontend and the GNU Taler merchant backend. This component should have a web interface, where payment buttons or payment forms will be configured. Additional goals include inventory management, where the seller can configure the available stock for an item and will get notified when their stock runs low. Currently, to accept payments with GNU Taler, people have to write their own code. What I propose to change is this mechanism. People will be able to communicate with the merchant’s backend via a simple API.
