If your credit/debit card is not accepted, it may be due to the following: 

• 3-D Secure must be active on the credit card/prepaid card.
• - The 3-D Secure procedure increases security when paying with a credit card/prepaid card on the Internet. With this procedure, customers additionally confirm electronic payments with a password, a TAN or a fingerprint. This setting can usually be activated via the eBanking of your card provider.
• The means of payment must have sufficient credit/limits.
• The means of payment must be valid.

If you have checked all these points, and it still does not work, you can contact us. Please provide us with the last four digits of your credit/debit card so that we can verify the transaction.
