I am trying to pay, but it keeps redirecting me to another page. Why?

If your credit card provider is redirecting you to another page to enter a security PIN or ask for additional authorization, please contact them directly. This usually happens when the credit card has implemented a 3D secure feature.

The transaction can also fail if it is not recognized as a common or safe purchase. In this case, the transaction will be blocked by the credit card provider. If this happens to you, please contact your credit card provider directly.
