PC Charge and IC Verify are credit card processing softwares; you use them instead of a swiping terminal. You as a developer cannot directly process a credit card thru the system; you need one of these packages running behind the scenes. Then you can communicate with the package from within VFP.

IC Verify has mostly left the desktop/LAN market; they did not really have an API anyway, it was a file based system. The gold standard these days is PC Charge. PC Charge is very strict about licensing, your client will need the proper licenses. PC Charge can be configured to work woth most major US credit card processors. The processor can give you a PC Charge setup sheet with all the parameters you will need.

Swiping is handled by an external swiper or a keyboard with a swiper built in. The data from swiping appears to the PC as if it comes from the keyboard. The swiping gives you an extra line of gobbledy-gook which you in turn include with the cc info.

The actual interface to PC Charge is pretty simple. You can use dll, ocx or file based. The ocx provides an ocx for credit cards, one for debit cards, etc. You create an object, fill in the properties with the CC info, then call the Send method. If you get the developer kit there is pretty good documentation.
