I was thinking of doing business with restaurants, and offering them SMS marketing services. One thing that blocked me was the issue of one-time usable SMS coupons.
The thing is most people do not have Internet on their phone, so I do not want to concentrate on mobile coupons that are opened through the browser.
I am with LIME and they have a coupon text redeeming system where the customer receives a text with the promotion code. However, what would stop the customer from going back to the store and showing the same text to get the same special again?
Looking for any input. Thanks.
