I am looking for a expert to integrate Verifone Vx810 Duet to my POS system.
Following are what I need: to send the payment amount to Vx810 duet terminal, and display a message hint "please swipe card...", then wait for the Transaction result "Aproved or Refused". I really do NOT want to know any information about the debate or credit card or pin, what I want is how to communication with Vx810, so I can avoid the casher to type in payment amount manually.
if you know how to communicate with Ingenico i3070. it is good news for me.
You just tell me the command to do it by RS232 or USB, you do not need to make code. I can make the communication code.
