Hello,

I have a question that doesn't have as much to do with VFP as it does with credit card validation by an application.

I'm developing a system that will need to interface with credit card companies in order to receive payments from customers.

The current set up involves a credit card machine (one of those with a keypad, a swipe slot, and a receipt printer).

Currently, we are able to void a transaction by using one of the functions of the keypad and entering the REF number of the transaction we want to void. Unlike a regular charge/credit combination, in which a charge appears on the cardholder's statement and then a credit when we refund the money to him, a voided transaction doesn't appear on a cardholder's statement. It's as if the transaction never occurred.

I'd like to know if the active-x's and other gizmos used to accept credit cards entirely by the vfp program would allow me to void transactions.

Any help and input would be greatly appreciated!!!!

Thanks!

Alex
