One-Click Cash Payments!
GNU Taler is an electronic payment system under development at Inria. We expect to make it operational in 2018. You can learn about Taler on this website, try the demo and look at our documentation.
Practical
Taler is easy to integrate with existing Web applications. Payments are cryptographically secured and are confirmed within milliseconds with extremely low transaction costs.
Stable
Taler does not introduce a new currency. Taler uses a digital wallet storing coins and payment service providers with escrow accounts in existing currencies. Thus, Taler's cryptographic coins correspond to existing currencies, such as US Dollars, Euros or even Bitcoins.
Secure
By design Taler does not suffer from many classes of security problems such as phishing or counterfeit. Thanks to its security features, Taler never rejects a legitimate customer due to a fraud-detection false positive.
Taxable
When using Taler, merchant's revenue is transparent for tax collection authorities. Unlike cash and most digital currencies, Taler helps prevent black markets. Taler is not suitable for illegal activities.
Private
When you pay with Taler, your identity does not have to be revealed. Just like payments in cash, nobody else can track how you spent your electronic money. However, you obtain a legally valid proof of payment.
Libre
Taler provides protocols and reference implementations that in principle enables anybody to run their own payment infrastructure, be it individuals, organizations or whole countries. Since the reference implementation is a GNU package, it will always remain free software.
Paying with Taler
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.
Receiving payments with Taler
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.

improvements and bug fixes, as well as a new, simpler to use
API for merchants that also enables the implementation of
GNU Taler wallets on platforms that do not support
WebExtensions.

components are on the GNU FTP mirrors.
