Why this matters
Drink tickets get screenshotted. Sponsor perks get forwarded. Booth staff need a clear answer while a line is forming.
If there is no way to verify a voucher on the spot, the same offer gets used by multiple attendees.
Coupon Carrier gives each attendee a unique voucher link. Staff validate it on the attendee'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 attendee's phone. No guessing during a rush.
No app downloads for staff or attendees. Validation happens in the browser.
The whole interaction takes under five seconds. Lines keep moving.
Every redemption is logged with a timestamp. Export CSV reports for sponsors, organizers, or internal review.
