GNU Taler

GNU Taler is a privacy-preserving payment system. Customers can stay anonymous, but merchants can not hide their income through payments with GNU Taler. This helps to avoid tax evasion and money laundering.

The primary use case of GNU Taler is payments; it is not meant as a store of value. Payments are always backed by an existing currency.

Payment are made after exchanging existing money into electronic money with the help of an Exchange service, that is, a payment service provider for Taler.

When making a payment, customers only need a charged wallet. A merchant can accept payments without making their customers register on the merchant's Website.

GNU Taler is immune against many types of fraud, such as phishing of credit card information or chargeback fraud. In case of loss or theft, only the limited amount of money left in the wallet might be gone.

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.

To receive Taler payments, a merchant needs a bank account in the desired currency. We provide supporting software in various programming languages to make the integration painless. The merchant's backend for Taler transaction processing can run on the merchant's premises or be hosted by a third party.

Merchant integration is simple, and customers can pay for products without even having to register an account.
