Blocking out certain credit cards

[PGelsman]

IS it possible to block out specific credit cards from being used on my site?

I have someone who is using the so called 'test credit cards' to buy products on my site, and instantly download the product.

 

I need help please.

 

Thank You.

I am assuming that you are using the standard credit card module (cc.php) that simply collects the credit card information.

The modual does not actually check the card for validity. I feel cc.php is useful, but in my opinion it shouldn't be used for downloadable products.

 

In layman's terms, the problem is that the module uses a formula to determine if the card number is valid and not if a card is good. Using the same formula you can get thousands of credit cards that would pass the validation test but may not be "real" cards. If you PM, me I'll send you to an online link that can create an unlimitted number of "test" cards.

 

You can create a "Black List" of test cards that you want to be denied, but a determined person would simply use a different card number.

 

HTH,
