What is Punch?
Punch is a customer loyalty program designed for small businesses. With Punch you can issue the equivalent of paper punch cards (buy 10, get 1 free) on the iPhone. It works just like a paper loyalty program. You determine the rewards you want to offer your customers.
But instead of punching a paper card, your customers record purchases using the phone’s camera to scan a bar code. Once a customer gets the required number of punches, he receives a reward. Customers track Punch Cards from many merchants in a single application. Punch also allows you to create coupons that appear whenever customers view your store on the Punch iPhone app.
