You will be directed to a page with important information regarding the registration of your card. Read through it and then tap on 'To Billwerk+'. Enter your card details as required and confirm them. Your card will then be verified, for example, via 3D Secure. Depending on the card and verification method, you may be asked for a code and/or password, or you may need to answer a security question, depending on the security measures set by your credit card provider.

It may happen that 0 EUR is reserved in your account during the registration of your card. This reservation will be removed after a few days.
