Lead Capture Forms on QR Codes: Setup Guide

SMLLR's Lead Capture Gate (Pro plan and above) is a small interstitial that appears the moment someone scans a QR code, asking for a single email or phone number before the redirect continues to your actual destination. Turning it on takes under a minute inside the QR editor — no separate page to build, no code to write. Every contact it collects lands directly in your account-wide Lead Hub, deduplicated against anything you've already captured through a landing page form or a CSV import. This guide covers exactly what the gate collects, how to configure and style it, and what happens the moment someone submits.

The gate is a single combined field, not a multi-question form: the scanner types either an email or a phone number, and SMLLR auto-detects which one it is (phone numbers are parsed India-first, but a full international +country number works too). That field is mandatory — it's a functional requirement to unlock the redirect, not a marketing opt-in, so there's no toggle to make it optional. Below it sits one more thing: an unchecked-by-default marketing-consent checkbox, with fixed wording you can't edit, that the scanner can leave unticked and still continue. There's no separate name field, no free-text question, and no way to add extra fields — if you need to collect more than a single contact detail before a human follow-up, that's what a full Landing Page form is for (see the comparison below).

The gate lives in the QR editor's Configure step, alongside your other redirect rules:

Since the title is the only headline a scanner sees, name the benefit rather than describing the mechanism — "Get 10% off your first order" reads better than "Please enter your details." Keep it short enough to read in one glance; the field below it does the rest. On the styling side, use the theme colors to match your brand rather than leaving the default dark theme on a QR code tied to a bright, colourful campaign — a jarring visual mismatch between the printed material and the gate can make scanners second-guess whether they landed somewhere legitimate. Whatever you change, keep the printed QR code itself at Level Q or H error correction and test it at your smallest planned print size, since the gate only ever appears after a successful scan — it can't fix a code that doesn't scan in the first place.

A hidden honeypot field silently discards anything a bot or script fills in, without creating a lead or showing an error, while the endpoint itself is rate-limited per IP address to stop a single source from being farmed. On a real submission, the value is validated and normalized — an email is lowercased, a phone number is parsed to E.164 format — and checked against your existing Lead Hub records: a match merges into that person's existing lead rather than creating a duplicate, and the redirect only fires once this completes successfully. If the field is empty or doesn't look like a real email or phone number, the scanner sees an inline error and stays on the gate rather than being sent through with bad data.

The two features solve different problems and both feed the same Lead Hub, so picking one doesn't fragment your data. Use the Lead Capture Gate when the destination itself is what matters — a product page, a WhatsApp chat, an app download — and you just want a single fast field in front of it, well suited to packaging, posters, and counter cards where friction has to stay minimal. Use a Landing Page's lead-capture form when the QR code's entire purpose is the page itself — a bio-link style destination or a dedicated campaign page — and you want to collect a name, email, phone, and a message in one richer submission before a human follows up. A retail counter card pointing straight to a catalogue is a gate use case; a QR code on an event banner pointing to a dedicated registration page is a landing-page-form use case.

Every submission appears in Leads Hub in your dashboard sidebar (Pro plan and above) — both as part of the account-wide lead list and, if you open the specific QR code, as a filtered list of just the leads that QR code's gate has captured. The top of the Leads Hub page shows four live counts — Total Leads, New (7 Days), Marketing-Reachable, and No Consent Yet — plus a breakdown of how many leads came from the QR gate versus landing pages versus CSV import. Search the list by email or phone, and click into any individual lead to see its full touchpoint history (source, device, city, and timestamp for every capture event) alongside its consent record.

The Lead Capture Gate, Leads Hub, and CSV import all require SMLLR's Pro plan (₹999/month, 50 QR codes) or above — the Premium plan (₹1,999/month, 150 QR codes) adds white-label branding and API access on top of the same lead-capture features. Every plan, including Pro, comes with a 14-day free trial and no credit card required, which is enough time to enable the gate on a live QR code and confirm leads are landing in your dashboard before committing.
