You will be asked to deposit a valid credit card directly during the registration process.
Currently, only credit cards or prepaid credit cards from Mastercard, Visa or Diners-Card are accepted.
Billing is retroactive to the beginning of the following month. If you have a prepaid card, make sure that you have sufficient credit, otherwise the registration will be rejected by the system.
With online providers such as Revolut, you must also ensure that settings such as the release for online transactions are active. Visa cards from Revolut issued abroad sometimes do not have a 3D-Secure function. Such cards are unfortunately not accepted by our system, as this additional security function is mandatory.
