Scan-Limit QR Codes: Create 'First 100 Customers Get 20% Off' Offers That Close Themselves
A qr code scan limit first 100 customers guide — how scan-limit redirect rules automatically switch a code's destination once a set number of scans is reached, and the one nuance (scans aren't redemptions) worth planning around before launch.
The "First X Customers" Problem Without This Feature
A "first 100 customers get 20% off" offer sounds simple until someone has to actually enforce the cutoff — watching a scan count in real time and manually swapping the destination the moment it hits 100 is unreliable at best, and most businesses either overshoot (the offer runs longer than intended, eating margin) or close it manually too early out of caution, cutting off genuine customers who would have been within the real limit.
How Scan-Limit Redirect Actually Works
SMLLR's scan-limit redirect rules (Basic plan, ₹1,999/month, and up) automate this directly: set a limit, a destination for scans within that limit, and a fallback destination for everything after. The first scans up to the limit land on the offer page; every scan after that lands on the fallback — a "this offer is full" page, a regular-price page, or a waitlist signup. The QR code itself stays active throughout; only the destination switches, with no manual monitoring required.
An Important Nuance: It Counts Scans, Not Redemptions
This is worth being precise about before launch: the limit counts scans, not confirmed purchases. If your actual goal is genuinely limiting the offer to 100 paying customers, set the scan limit somewhat higher than 100 to account for people who scan, look, and don't buy — a scan limit set exactly at your target redemption count will almost certainly close the offer before 100 people actually buy anything. For a precise count of real conversions rather than scans, pair this with Lead Hub (Pro plan, ₹4,999/month) to capture an actual claim or signup behind the offer page, which gives you a conversion number distinct from the raw scan count.
Setting Up a Real Offer
A concrete example: a retail launch wants to give the first 100 scanners a 20% discount code. Set the scan limit to a number somewhat above 100 (say, 130, based on an estimated scan-to-redemption rate), the limit destination to a page revealing the discount code, and the fallback destination to a page offering a smaller, always-on discount instead — so even customers who miss the flash offer get something, rather than landing on a page that reads as a dead end.
Common Use Cases Beyond Retail Discounts
The same mechanism fits several genuinely common scenarios:
- **Flash sales and limited-edition drops**, where the scarcity itself is the marketing hook.
- **Event capacity caps** — a QR code on event marketing that closes registration automatically once a venue's capacity is reached.
- **Early-access or fast-pass offers**, rewarding the first scanners specifically with a genuine first-mover benefit rather than a generic one.
Combining With Other Features for a Fuller Picture
Group multiple scan-limit codes (one per store or placement) under a campaign in Campaign Manager (Basic plan, ₹1,999/month, and up) to compare how quickly the limit was reached at each location — a useful demand signal for sizing next time's limit or allocation per store. And watch scan velocity specifically around the cutoff: a limit reached within minutes of launch tells you something different about demand than one that takes days, even though both technically "sold out."
Create your QR code on SMLLR, set your scan limit once, and let the offer open and close itself exactly where you intended.

Frequently Asked Questions
What plan do I need for scan-limit redirect rules?
Scan-limit redirect rules are available from the Basic plan (₹1,999/month, and up).
Does the QR code stop working once the scan limit is reached?
No — the code stays active. Only the destination changes: scans up to the limit land on the offer page, and every scan after that lands on the fallback destination you set.
If I set a scan limit of 100, does that guarantee exactly 100 redemptions?
No — the limit counts scans, not confirmed purchases or claims. If your actual goal is 100 redemptions, set the scan limit higher than 100 to account for people who scan but don't follow through, or pair it with Lead Hub to track actual conversions separately from raw scans.
What should the fallback destination show once the limit is reached?
Something other than a dead end — a "this offer is full" message, a smaller always-on discount, or a waitlist signup, so customers who miss the limited offer still have a reasonable next step.
Can I use scan-limit redirects for event capacity rather than a discount?
Yes — the same mechanism works for capping event registration automatically once a venue's capacity is reached, closing the signup destination without manual monitoring.
How do I compare scan-limit performance across multiple store locations?
Create a separate scan-limit QR code per location and group them under a campaign in Campaign Manager (Basic plan, ₹1,999/month, and up) to compare how quickly each location's limit was reached.
