Stop Coupon Fraud.
Lock Down Every Scan.
QRTRAC stops voucher leaks at the source. Run city-wide aid programs, local restaurant promos, or high-value event ticketing without worrying about screenshots, duplicates, or double-scans.
Time-Based Expiration
Set exact expiration windows. Limit a grocery voucher to 24 hours post-issuance. After the clock runs out, the QR scan fails instantly.
Single-Use Assurance
One scan kills the code. Our system logs the checkout instantly. We track device and IP footprints to block bot networks and screenshot sharing.
Authorized Gates
Keep the power in your staff's hands. Require a physical cashier scan or a secure staff pin to complete the transaction. Customers cannot trigger redemptions on their own.
Protecting Public Programs:
The Authorized Redemption Gate
Public agencies and city governments can't afford leaked voucher budgets. When the City of Sacramento distributed emergency housing vouchers, they needed to make sure only authorized motel clerks could check families in. They could not risk users self-redeeming codes by accident.
The Clerk Validation Flow
User presents phone screen → Motel clerk scans user's QR → Clerk enters secure lobby PIN → Database voids the voucher instantly.
This workflow stops accidental clicks on the bus. It ensures every dollar of your program funding goes directly to verified service providers.

Manage Multi-Location Rollouts
Set complex verification rules across hundreds of locations from one central dashboard.
Multi-Location Rules
Set minimum cart spends (like a $20 minimum) or cap total global redemptions across your entire franchise network.
GPS-Based Validation
Require customers to be physically inside your shop. The scanner checks their coordinates before approving the discount.
Cashier PINs
Issue unique codes to every branch or cashier. Trace every free meal or discount back to the specific employee who validated it.
Real-time Voiding
The millisecond a clerk hits confirm, the code dies everywhere. This blocks high-speed fraud runs where users share a code across multiple checkouts.
What Happens on the Second Scan
Every coupon campaign eventually meets the same moment: a customer presents a code that has already been used. Maybe they forgot. Maybe a screenshot went around a group chat. What separates a controlled campaign from a margin leak is whether that moment is decided by your settings or by whoever is standing at the register.
A definite answer, not a broken page
A spent coupon does not fail silently. You decide in advance what a used code returns: a plain message you write yourself, or a redirect to any URL you choose. Most teams point spent codes at the next live offer, which turns a dead scan into a second chance at a sale.
No judgement call at the counter
Staff never have to decide whether a code looks legitimate. Redemption sits behind a password only your team holds, so a customer cannot mark their own coupon as used, and a screenshot cannot walk itself through the gate. The counter either accepts the code or it does not.
That single detail removes the most expensive argument in retail promotions — the one where a queue builds while an employee decides whether to honor a discount they cannot verify.
Redemption Per User
Cap how many times one person can claim the same offer. Set it to 1 for a strict one-per-customer promotion, or higher for a punch-card style campaign.
Total Redemptions Limit
Cap the whole campaign. Once the limit lands, further scans stop converting — the ceiling on your discount exposure is a number you set, not a number you discover afterwards.
Editable After Printing
Limits, expiry, and destination all change from the dashboard. A campaign that is running hotter than forecast can be tightened the same afternoon without a reprint.
What If the Store Has No Signal?
This is the question that decides most retail rollouts, and it deserves a straight answer rather than a marketing one.
A coupon QR code is dynamic by design. The code on the flyer is a pointer, and the offer, the expiry, and the redemption count all live on QRTRAC's side. That is exactly what lets you change an offer without reprinting — and it also means a redemption has to reach the network to be recorded.
In practice this matters less than teams expect, because the scan happens on the customer's phone over their own mobile data. Store WiFi going down does not usually take the coupon with it. The genuine edge cases are basements, rural sites, steel-framed warehouses, and event tents — places where the customer has no bars either.
Three ways teams handle true dead zones
Print the code beside the QR
Put a short human-readable coupon code next to the QR. Staff write it down when the network is out and reconcile the batch later. You keep the audit trail; you just record it a few hours behind.
Use a static code for fixed value
If an offer will never change and you do not need live counts, a static text QR code carries the value inside the code itself and reads with no connection at all. You trade analytics for independence.
Keep the offer page light
Weak signal is far more common than no signal. An offer page carrying a hero video will stall on one bar; a page carrying text and a logo will not. Design the landing page for the worst connection in your worst store.
