You can use debit cards, credit cards and Q8 Liberty cards in the app. All you have to do is activate them once/add them to your list of payment and fuel cards. After that, you can use them every time you refuel. If you want to pay by debit card, you don’t even have to add a card at all. Once you have activated this payment method, you will automatically be redirected to the Bancontact app or another app with the Bancontact functionality on your smartphone. If you have not yet installed this app on your phone, you will first be redirected to your app store to download it.
