Apple Pay is a payment system from the US company Apple for in-house mobile devices
You can choose Apple Pay in the MOIA App Menu under Payments. If you have already deposited a form of payment in your Apple Wallet, Apple will automatically sync all apps stored on your device
MOIA will automatically show you the Apple Pay Option in the Menu
You have never paid with Apple Pay, but would like to do that? No problem, you just have to add a payment method in your Apple Wallet
Please note, that MOIA does not accept American Express or Maestro, also not within Apple Pay
