Hello JoJo3
If your credit card use «3-D Secure Code» as a security element, a page will appear during the payment process requesting identification (password, SMS, fingerprint, Face ID or Transactions App). This will clearly identify you as the cardholder.
Please check with your credit card provider if you have activated this service. Otherwise it is not possible to use this credit card as a payment method in your customer account.
I wish you an excellent day.
Kind regards, RahelW
