There is no 100% protection against card fraud. Unfortunately, this can happen with any card, even from other banks. There are many ways in which fraudsters manage to charge a card – they copy the card details (e.g. in a bar or restaurant), they steal card details from a retailer, or they use special computer programmes with which they «guess» card details over many attempts.

For this reason, there are standardised processes that can be used to report a fraudulent card payment to Mastercard. If you find unknown transactions on your account, please proceed as follows: «Standard procedure for card fraud».
