I thought the idea might give others something to think about.
From what I understand, the way it works is this.
1) Customer opts in to receive a coupon via SMS. The customer then receives a UNIQUE coupon code sent instantly to their mobile. This code is unique so it can only be used once.
2) Customer goes to pay at the store and instead of handing their phone over and showing a coupon code, they actually enter the coupon code right into the EFT/Credit Card terminal and it automatically deducts that amount off the total purchase price. Once that coupon code has been entered in it then becomes invalid so no one else can use it.
3) The shop can then follow up with those customers via SMS. They can even send additional coupon offers to drive people back into the stores during quiet times. All the while they can be confident the coupons are not being abused and shared around.
What do you think? Good idea? Bad idea?
