Why this matters
Retail vouchers are redeemed at the register, service desk, or checkout. Staff see a code on a phone and have to decide whether to accept it.
If there is no way to check whether a voucher has already been used, the same offer gets redeemed multiple times.
Coupon Carrier gives each customer a unique voucher link. Staff verify the offer on the customer's phone and mark it as used in real time.
Reuse is blocked automatically. Screenshots, forwards, and re-scans all show “Already Used.”
Staff see an instant visual change from “Valid” to “Used” on the customer's phone. No guessing at the register.
No app downloads, no scanner hardware. Staff verify offers on the customer's own device.
Runs in the browser. Launch a campaign without waiting on IT or point-of-sale changes.
The whole interaction takes under five seconds. Cashiers don't slow down the line.
