You need your PIN to pay for purchases in different situations. With your PIN, you verify payments at store checkouts and withdrawals at ATMs.
If you are paying for purchases under 50 euros, all you need to do is tap your card on the payment terminal – there is no need to enter your PIN. When you are paying with your card that has the contactless payment feature for the first time, insert your card into the payment terminal and enter your PIN.
