If the credit card has expired, will the AIM Refunds that I do in XML and PHP work properly? For instance, I was thinking of storing the last digits of the credit card plus the credit card expiration date in my database in encrypted form. When I need to do a refund, these are already on file and can run with these instead of prompting the customer over the phone or by email. But if in the event that the customer wants a refund past the date of their credit card expiration, will it still work or will I need to prompt them for their latest credit card expiration date?
