I am in charge of a Point of Sale system written in VFP 8.

We are currently looking for ready made solutions you may already have developed for interfacing a VFP system (my program) with a EMV (chip reader) Terminal.
I imagine starts with some sort of Parameter Exchange (such as the transaction amount) and then initiating the Credit / Debit card processing, then sending back the Result.

We have not yet made any decision on the brand or model of terminal(s). We are currently looking for the ability to interface to as many of these terminals as possible.

Thank you.
