2.2.2. Používanie aplikácie na mieste predaja

A simple way for merchants to accept GNU Taler payments is the use of the point-of-sale app. The app can be installed on a phone or tablet and connects to a GNU Taler Merchant Portal account.

The main merchant workflow is:

1. Sign in to the Merchant Portal account.

2. Create an amount-based order or an order by inventory.

3. Show the generated payment QR code to the customer, or take any cash or card payments and then show the Taler QR code for the balance.

4. Wait for the customer’s GNU Taler wallet to complete the payment, or collect the receipt in the app for an order paid entirely in cash or by card.

5. Inspect the order history or create a refund when needed.

Additional workflows include:

• Taking payments with SumUp payment terminals.

• Using a Taler Payment Device.

Follow these tutorials for each task:

• Sign in to the Point-of-Sale App

Try it in the sandbox

You can try the point-of-sale app with the public GNU Taler demo Merchant Portal. Use the Merchant Portal URL https://backend.demo.taler.net with username sandbox and password sandbox.

This is a shared demo environment for testing and experimentation. It does not process real money, and demo data may be changed or removed by other users.

To use the app with your own hosted merchant account instead, see Obtain an Instance on my.taler-ops.ch.
