Try to pay by using the card’s chip and PIN option, as this is initially required to activate the contactless feature.

If the transaction is still declined:

• Please ask your merchant whether the Debit Mastercard is an accepted payment method. The Debit Mastercard card is accepted at most Belgian POS terminals, but there may be some exceptions.
• Try a different ATM or point-of-sale machine.
• Verify that you have sufficient funds and that the card is active, by logging in to your app or your personal platform.

Should the card fail for technical reasons, you can go to “Settings” and click on “Replace Card”. Make sure you invalidate your defective physical card by cutting it into pieces.
