If you can't register a credit, please try the following:
Please confirm that your payment information is correct
If there is an error in the information, such as the credit card number or expiration date, the registration will fail.
Please confirm that all your information was entered correctly.
Please contact your credit card company
Your credit card may fail to register even if there are no errors in your credit card information.
We are introducing 3D Secure to handle credit card payments safely on FANBOX. If an error occurs when registering a credit card, there might be an issue with 3D Secure not being able to certify the credit card.
Furthermore, FANBOX will not know the reason why verification may have failed. We apologize for the inconvenience, but please contact your credit card company if you have any issues.
