How does mobile payment with the Lunch-Check app work?

The «mobile payment» function currently only works on Android devices with the contactless func-tion (NFC). Unfortunately, it is not yet known when Apple iPhone’s can also be used for mobile pay-ment, because Apple Pay cannot be used.


  • Activate the «NFC» function in the device settings.
  • The Lunch-Check app does not have to be used as a standard app. Depending on the device type, you can select «prefer running app» or «replace default app when another payment app is open».

Payment procedure:

  • Open the desired card in the Lunch-Check app.
  • Hold the phone like a physical card against the contactless reader of the payment terminal.
  • The phone vibrates and a green tick appears on the display if the transaction was successful.
