How do I make a purchase with my card? Permanently deleted user 03 April 2024 11:13 Updated You can use your VIABUY card to make purchases in shops and online. For your purchases in shops, you can use either PIN payments by inserting the card in the POS terminal and using your PIN code to authorise the transaction, or you can use the contactless function by simply tapping the card on the POS (for payments under EUR 50). For online payments, you'll need to use your long 16-digit card number, the expiry date and the CVV code (3 digits) that you'll find on the backside of your card.
