API coding to connect Point of sale system and card reader

Does anyone have a referral for completing the following task?
I have a restaurant utilizing Aloha pos for checking out and we would like the folks that are members at the resort to have discounts for holding a member card that would be scanned either upon paying their bill or once they walk in the door like a gym does.

Specifically, what is it in Infusionsoft that you would like communicated from the POS system?
