Which payment or fuel cards can I use in the app?

Debit card, credit card or Q8 Liberty card, you can use them all in the app. Just activate them once/add them to your list of payment and fuel cards. After that, you can use them every time you refuel. For payments with a debit card, you also have to register your card once to the app. Once your card is linked, you start the transaction in our app by just one click using your banking app.
