Hi 👋🏼 Hans, it kind of depends. In the Netherlands we aren’t always very credit or debit card minded. So, the best way is to pay with a Maestro card. Most of the times you can see by the stickers on the window what kind of cards they accept.
Having that said, most of the restaurants I know here do accept credit or debit cards. Do you see a particular error message in the app or on the terminal?
