Are there any credit card validation companies out there who will accept a credit card # via Perl call, and return a VALID or INVALID response?
I would like to validate credit cards on-the-fly with as little expense as possible :-) If there are any 3rd party companies who charge per transaction/validation rather than set monthly fees, that would be great. Actually, if anyone has any better ideas, this would also be helpful.
Anyone have any ideas on this?
