Your ABN AMRO MasterCard is equipped with the 3D Secure security function as standard. For some online transactions you may be asked to enter a ‘one-off password’ (OTP code). This ‘one-off password’ has 6 digits and is sent via SMS to your mobile phone, which is registered with credit card provider Advanzia. When making the online payment, you will receive the ‘one-off password’ and you can enter it on the shop’s website to complete the transaction.
