Events are where QR codes shine brightest. You have a captive audience, a physical space full of touchpoints, and dozens of moments where a quick scan beats a long URL. Here's how to use QR codes at every stage of your event.
Before the Event
Registration
Put a QR code on your event invite, social media post, or email. It links to your registration page — Eventbrite, Google Forms, Luma, or your own site. Scanning is faster than typing a URL, especially on mobile.
Tip: Use a dynamic QR code so you can switch from the registration page to a "Registration closed" page after the deadline — without changing the QR on materials already distributed.
Promotion
Print QR codes on physical promo materials: posters, flyers, banners at partner venues. Track scans to see which placement drives the most registrations.
Create a separate dynamic QR for each channel — one for the poster at the co-working space, one for the flyer at the café, one for the partner's newsletter. Compare scan analytics to see which channel performs best.
During the Event
Check-in
Instead of searching names on a list, attendees scan a QR code from their confirmation email at the entrance. This works with most event platforms — Eventbrite, Luma, and others generate unique QR codes per ticket.
For simpler setups, a single QR code at the entrance linking to a check-in form (Google Forms with name field) works fine for small events.
WiFi
Display a WiFi QR code at the entrance, on screens, and at each table. Hundreds of people trying to connect at a conference? A QR code eliminates "What's the WiFi password?" completely.
See our dedicated guide: WiFi QR Code.
Schedule and Info
Instead of printing 200 copies of the schedule, put a QR code on the entrance screen and at each session room. Link to a Google Doc or Notion page with the live schedule — update it in real time if sessions shift.
Feedback
Place QR codes at session rooms or on the tables. Link to a short feedback form (Google Forms, Typeform). People give more honest feedback when they can type it privately right after a session, rather than being asked face-to-face later.
Networking
Give each attendee a badge with their personal vCard QR code. When two people meet, they scan each other's badges instead of exchanging paper cards. Contact saved instantly.
For speakers: put a QR code on the last slide with their contact info or LinkedIn profile.
After the Event
Follow-up
Send attendees an email with a QR code linking to event photos, recordings, slides, or a community page. This works especially well for printed thank-you cards sent after corporate events.
Survey
A QR code in the follow-up email or on the exit signage linking to a post-event survey. Catch people while the experience is fresh.
Measuring Success
With dynamic QR codes from qree.app, you can measure:
- Which promotional channel drove the most registrations (separate QR per channel)
- How many people actually used the WiFi QR
- How many feedback forms were started via QR scan
- Peak scanning times (useful for planning next year's event)
