The cancellation of the credit card payment can have various reasons, which are usually difficult to identify remotely. Our payment provider checks various information during a payment for security reasons and may also cancel payments. Please understand that we cannot describe the checking mechanisms in detail.
The following factors may be responsible for the cancellation of a credit card payment:
1. You are on the Internet with a static or fixed IP address (often with cable providers).
2. You are abroad and therefore do not have a German or Austrian IP address.
3. You are using a credit card that does not originate from Germany, Austria or the Netherlands.
4. The 3D Secure or Verified by VISA procedure is not activated for your credit card or the security codes have not been entered or have not been entered correctly.
5. You are using a "secure browsing" function, which is usually integrated in the antivirus protection (can usually be temporarily disabled)
6. The limit for orders with credit card has been reached or exceeded
7. If you are automatically redirected back to our online store without payment, you should check the entered credit card data again for spelling or other errors.
The networks of companies or universities are also often responsible for the cancellation of payments.
In any case, please make sure that you have your 3D-Secure-Code (MasterCard) or Verified by VISA access or verification data at hand, if your credit card is equipped with this function. Also, make sure that no anti-virus program or ad-blocker is preventing the payment (disabling it may help).
If your payment still doesn't work, giropay may be another payment option for you.
Notice:
For business customers from Austria, payment by credit card is not available due to VAT deduction. This does not apply to private customers.
