Possible errors

“Touch”: nothing happens to the guest on Android

Employee shows the panel "Tach" and touches his phone to the guest’s phone. On Android For a guest, payment via NFC often does not start until the phone blocked (the screen is turned off or locked).

What to do:

1. Ask a guest unlock phone.
2. Touch the phones to each other again - the bank payment script should open on the guest's side.

While the guest's phone is locked, the employee's phone can only have vibration - This is fine. After unblocking the guest, touch again.

NFC is disabled

On both phones it must be enabled in the settings NFC. Without this, Touch will not work - use QR on the same payment screen.

The required bank application does not open

If, when creating an account, the employee’s application does not indicate Guest OS or bank, the link in NFC or QR may not open in the application the guest usually uses to pay.

What to do:

• Please check the guest's bank in the app before showing the payment.
• If in doubt, show me QR: The guest will scan it at their bank.

If Touch doesn't help

On the payment screen, swipe to the panel QR - this is the same account, a different way of transferring the link. QR works both when NFC is not available and when the guest’s phone is on iOS (for iPhone “Touch” in the same form as on Android, not usually used).
