    Despite the fact that we announce that we only accept Visa and Mastercard, we had a customer repeatedly try to enter her Amex card for payment.

    As a result, the merchant account provider charged us $1.75 per attempt.

    Yes, we need to change merchant account providers, but that's another story.

    Regardless, is there a setting to pre-validate the card type before it goes to the gateway? Where it checks for the starting digit?

    Amex starts with 3, Visa starts with 4, MC starts with 5 and Discover with 6, so it could be an easy check.

    In cart setup under required fields there is a box that says validate credit card fields. Not sure if it would weed out Amex or not. Let us know if it does or doesn't help.

    Typically when using a gateway it collects the card number. So I think the message about which cards you accept is just for information in this case - there's no facility to enforce it before the card number is entered.

    So the question may be whether you can ask for the first digit in the cart and reject other than 4 or 5. I guess so although a customer could still bypass that step.

    Maybe others can suggest what you need to add to the cart.

    Anyone else have any ideas how to only allow the entry of credit cards that we accept?

    We *clearly* have written in several places on the site that we only take Visa/MC, but people still insist on entering numbers from Amex and Discover and we get charged every time.

    It's frustrating.

    Hi,

    I had the same problem early in the year, I emailed Mal but he said there was nothing he could do.
