Credit Card Identification Problem....Help


INDY GS

Recommended Posts

In our webstore, the customer sees the "Diner's Club" when they use a Mastercard and sees "Australian Bank Card" when they use a Discover Card. The visa card is just fine.

 

Can anyone explain why this is happening. The numbers are correct. They run just fine, it is just a visual error when submitting and then looking at the invoice. Why is this happening.

something wrong with the script, I suggest that you use some other cc processing thing, like site securetrading or similar, because they are much more secure and they don't make any mistakes...

 

 

We are collecting the info from the customer and manually running the transaction thru a terminal. We only operate the store seasonally, and for limited items.

 

Any other suggestions? Thanks!

Are you using the CC module that comes with osCommerce? if so check your \includes\classes\cc_validation.php file, it should look like this:
