What is SMLLR and How Does It Work?
Understand what SMLLR is, what problems it solves, and how dynamic QR codes differ from ordinary ones.
What is SMLLR?
SMLLR is a dynamic QR code management platform built for Indian businesses. It lets you create QR codes whose destination can be changed at any time — even after the QR code is already printed — without needing to reprint or redistribute anything.
Instead of being locked into a single URL forever, your QR code becomes a live, intelligent link that you can update, redirect, track, and target based on who scans it, where they are, what device they are using, or what time it is.
Static QR Codes vs. Dynamic QR Codes
Most QR codes you encounter are static — the destination URL is baked permanently into the QR pattern itself. If you want to change where the code points, you must generate a brand-new QR code and reprint it everywhere.
| Feature | Static QR Code | Dynamic QR Code (SMLLR) |
|---|---|---|
Change destination URL | Not possible | Yes, anytime from dashboard |
Scan analytics | None | Full — device, location, time, OS |
Device-based routing | No | Yes — iOS, Android, Desktop |
Geo-based routing | No | Yes — country, state, city |
Schedule-based routing | No | Yes — by time and day of week |
Pause or deactivate | Not possible | Yes, instantly |
Set expiry | Not possible | Yes — by date or scan count |
GST-compliant billing | N/A | Yes |
How SMLLR Works — The Basics
Here is what happens when someone scans your SMLLR QR code:
The entire redirect process happens in milliseconds. Visitors do not experience any delay.
A person scans the QR code
Their phone camera reads the SMLLR short-link embedded in the QR pattern.
SMLLR receives the scan
Our servers instantly detect the person's device type, operating system, browser, approximate location, and the current time.
Rules are evaluated
If you have set any redirect rules (geo-targeting, device targeting, scheduled routing, scan-limit routing), SMLLR evaluates them in priority order to decide the destination.
The person is redirected
The visitor is sent to the correct URL — your website, WhatsApp, a landing page, a PDF, or any other destination you configured.
Scan data is recorded
The scan event is saved to your analytics dashboard, including device, OS, browser, location (city, state, country), and timestamp.
