Question: What digital coupon services are out there to prevent user fraud, re-printing, sharing direct links etc?
Coupon Manager does it well.It allows merchant to limit Coupon print per user, Checks fraud by providing unique code and letting merchants cross-check for those unique codes with their Coupon Manager backend and then mark it as Redeemed, Sharing direct link wont do anything if merchant has set the voucher/coupon code to display only to registered users. These and more.
