Hello, I have a 4GL application that I need to do credit card validation with. They currently use a MAP PC to verify the card and they type the verification # into the 4GL screen. I talked to my credit card vendor and they recommended something called a POSPORT (??), anybody have any experience with one of there? Especially doing it from 4GL or C..... Thanks, Gary Mitch@lexmark.com
