Frequently asked questions

We fulfil 100% of Mastercard's security requirements. Security is also guaranteed with a simpler 4-digit PIN and ultimately any potential damage is covered by Mastercard. In practice, the advantages of the internationally standardised PIN outweigh the theoretically higher security of a PIN with a higher number of digits. Further information on security:

Experience shows that 6-digit PINs hardly offer higher security, as simpler combinations are usually chosen.

The proportion of credit cards that are physically stolen and used with a PIN is extremely low. Fraud on online sites or by stealing account and card data is proportionally much more frequent.

For increased security, you can temporarily block the card yourself at any time in the app (under «Profile» and «Your card») and unblock it again for a payment.
