Payment by credit card is considered secure, fast and uncomplicated worldwide, even for payments on the Internet. As the cardholder, you enter your credit card number, the appropriate expiry date and the corresponding card verification number.
After real-time verification of your credit card number by our payment service provider Stripe, it may happen that a payment is not made. The most common cause is the unintentional incorrect entry of credit card information.
If you can already rule this out, then it is probably due to a rejection by your bank. Check whether your credit card is activated for international payments and transactions via the Internet. A possibly exhausted credit card limit can also be the cause of an unsuccessful payment.
Detailed information can be obtained from your bank. You will usually find a service number on the back of your credit card.
