I have written code before for a similar task. It was for a POS application that communicated with a terminal using ZVT protocol. I am also familiar with the OPI protocol. What do you need specifically? Each terminal provider also publishes their own API and SDK for such tasks. You need to determine which terminal you will be using, and for what specific tasks.
