Due to a new EU directive, new security measures have been in place since 2021 for online purchases with a credit card.
For security reasons, so-called 2-factor authentication (3D Secure) is now mandatory. In addition to entering the card details, there is a further authentication step in which it is confirmed that the credit card holder has actually initiated this payment.
Please note that the way the authentication is done (e.g. via SMS Tan or via App) depends on your bank and we have no influence over it.
The 2-factor authentication procedure must be activated for you by your bank before it can be used for the first time.
If you have any questions or problems, please contact the bank from which you received your credit card.
