A digital wallet can be an app in your mobile phone, a smart watch, a tablet or a computer that keeps track of your cards when you shop. They act as a means of payment worldwide. However, in situations where you have to use your card at a payment terminal, the purchase won't work with mobile payment, for example, at petrol stations or parking machines.

You can choose which of your cards you would prefer to pay with, and can place it at the top of your digital wallet. However, you can always choose which card you want to use as a means of payment.
