Scan and win QR campaigns
Scan-and-win is the most emotionally effective QR mechanic available and the easiest to run badly. Done well it produces participation rates that a flat reward cannot buy at the same cost. Done badly it teaches an entire channel that your promotions are rigged, and that belief does not reverse.
A scan-and-win campaign gives every scanner a chance of a variable prize rather than a fixed reward. At the same average cost it produces materially more scanning than a flat reward, provided the odds are published, every scan pays something, and large wins are paid fast and visibly. Typical participation runs 25–45% of eligible units in consumer campaigns and 55–80% in trade campaigns.
Why variance outperforms a flat reward
A flat ₹5 per scan becomes invisible within a quarter — it is priced in, and attention decays. The same ₹5 average delivered as a distribution (most scans ₹2–3, occasional ₹500, rare ₹25,000) generates markedly more scanning at identical budget, because people talk about outcomes rather than averages. One visible large winner in a district does more than the same money spread across ten thousand small payouts.
Designing the prize structure
| Tier | Share of pool | Typical value | Purpose |
|---|---|---|---|
| Guaranteed floor | 55–70% | ₹2–10 | Every scan pays; nobody feels cheated |
| Mid prizes | 15–25% | ₹100–1,000 | Frequent enough to feel attainable |
| Large prizes | 10–20% | ₹5,000–50,000 | The story that travels |
| Grand prize | 3–8% | Gold, two-wheeler, trip | Campaign identity |
The four rules that keep it credible
- Publish the odds and the top prize. On pack and in the app. A campaign that feels rigged is worse than no campaign, and the trade compares notes constantly.
- Guarantee a floor. Every scan pays something. A zero-value result after the effort of scanning reads as an insult, and it is the single fastest way to kill participation.
- Pay the big wins within 24 hours, publicly. Photograph the winner, with permission, and let the district see it. Unpaid or slow-paid large prizes are the story that actually travels.
- Never expire silently. If there is a validity window, state it on pack and remind members before it lapses.
Legal and compliance considerations in India
This is not legal advice and you should take your own, but the questions that come up every time:
- Skill versus chance. Pure-chance prize promotions are treated differently across Indian states, and some states restrict them. Many brands add a skill element or structure the campaign as a purchase-linked reward rather than a lottery.
- Terms and conditions must be published and accessible from the pack, including odds, validity, eligibility and the dispute route.
- Section 194R applies to trade participants: prizes are benefits, and they aggregate per PAN toward the ₹20,000 threshold. See the 194R guide.
- Prize tax under Section 194B applies to winnings above the threshold, with different mechanics from 194R. Get finance involved before launch, not after the first large winner.
- Consumer protection rules on misleading promotions apply to how the odds and prizes are represented.
Fraud controls specific to scan-and-win
- Prize concentration. Cap wins per member per period, or a small group will harvest the large tiers.
- Insider knowledge of winning codes. Winning outcomes should be determined at scan time by the platform, never pre-assigned to specific printed codes that someone could identify in advance.
- Bulk scanning to farm chances. Velocity caps and the same geo-clustering used in QR fraud prevention.
- Claim-stage identity checks on large prizes only, so routine small wins stay frictionless.
That second point is the one that destroys campaigns. If winning codes are decided at printing, the list exists somewhere, and lists leak. Determining the outcome at scan time removes the asset entirely.
Realistic benchmarks
| Campaign type | Participation | Note |
|---|---|---|
| Consumer FMCG, on-pack | 25–45% of eligible units | Depends heavily on prominence and instruction clarity |
| Trade, in-pack, existing members | 55–80% | Members already enrolled and already scanning |
| Trade, cold audience | 15–30% | Enrolment friction dominates the number |
| Festive window, existing base | 65–85% | Seasonal attention plus higher prize values |
When not to run one
Scan-and-win is a tactic, not a program. It is the wrong instrument when you need predictable earnings to change specification behaviour, when members are new and need proof the scheme is real (pay flat first, add variance later), or when your payout reliability is not yet boring. A campaign that generates ten thousand simultaneous wins on a rail that fails 6% of payouts will produce more damage than engagement. The broader comparison is in digital scratch cards versus in-pack coupons.
Frequently asked questions
What is a scan and win campaign?
A promotion in which every product QR scan gives a chance of a variable prize rather than a fixed reward. At the same average cost it produces materially more scanning than a flat reward, because people talk about outcomes rather than averages — one visible large winner does more than the same money spread thinly.
How should scan and win prizes be structured?
Roughly 55 to 70% of the pool as a guaranteed floor of ₹2 to 10 so every scan pays something, 15 to 25% in mid prizes of ₹100 to 1,000, 10 to 20% in large prizes of ₹5,000 to 50,000, and 3 to 8% for a grand prize such as gold, a two-wheeler or a trip.
Should scan and win odds be published?
Yes, on pack and in the app, along with the top prize. A campaign that feels rigged is worse than no campaign, and the trade compares notes constantly. Publishing odds costs nothing and is the main thing separating a campaign people trust from one they suspect.
Are scan and win campaigns legal in India?
Prize promotions are treated differently across Indian states and some restrict pure-chance schemes, which is why many brands add a skill element or structure the campaign as a purchase-linked reward. Published terms, Section 194R for trade participants and Section 194B prize tax all apply. Take your own legal advice before launch.
How do you stop scan and win campaigns being gamed?
Determine winning outcomes at scan time rather than pre-assigning them to printed codes, because any list of winning codes will eventually leak. Then cap wins per member per period, apply velocity caps and geo-clustering against bulk scanning, and run identity checks only on large prize claims so small wins stay frictionless.
What participation rate should a scan and win campaign expect?
Roughly 25 to 45% of eligible units for consumer on-pack campaigns, 55 to 80% for trade campaigns among already-enrolled members, 15 to 30% for a cold trade audience where enrolment friction dominates, and 65 to 85% during festive windows with an existing base.
