I'm wondering if anyone has any experience in offering coupons for their clients via QR codes?
Basically, I'm wanting to tap into the coupon market via electronic means. Instead of having people print off coupons and waste paper, I'm wanting to find a way for them to show a coupon on their phone to the merchant. Then the merchant will have the ability to track that one way or another.
I'm not wanting to out source an app being developed for this purpose. Does anyone know of a way I could do this via QR codes or another method? Just trying to figure out the best way to offer this service.
