QR codes for events let guests check the schedule, join the Wi-Fi, find the venue map and leave feedback from their phone — without you reprinting anything when plans change. Here are 12 uses that work and how to set them up.
12 ways to use QR codes at your event
- Registration and RSVP — link to your signup form on posters and invitations.
- Live agenda — one code on every sign that opens the latest schedule.
- Venue map — help guests find rooms, toilets and exits.
- Wi-Fi access — guests join with one scan instead of reading out a password.
- Speaker pages — bios, slides and social links for each talk.
- Sponsor booths — track which sponsors got the most interest.
- Networking — attendees share their contact card or LinkedIn.
- Food and drink menus — update when items sell out.
- Photo sharing — link to a shared album guests can upload to.
- Donations — link to your payment or fundraising page.
- Feedback survey — place it at exits and on the closing slide.
- Post-event content — recordings and slides once they're live.
Why event QR codes should be dynamic
Events change. Rooms move, sessions run late and links get replaced. A dynamic QR code points to a short link you control, so you can update the destination after the signs are printed. You also see how many people scanned each code and when.
Use one event page instead of ten codes
Too many codes confuse guests. Put the agenda, map, Wi-Fi, menu and feedback form on one mobile page, then print a single QR code everywhere. With Linkly you can build that page free at /link-in-bio and highlight the next session at the top.
Placement and size tips
- Entrance signs: at least 10 cm wide so people can scan from a few steps away.
- Table cards and badges: 2.5–3 cm is enough.
- Stage screens: keep the code on screen for 20+ seconds.
- Always add a short caption like 'Scan for the schedule'.
- Test every code under the venue's real lighting before the day.
How to measure results
Create a separate dynamic code for each placement — entrance, tables, stage — and compare scans afterwards. You'll learn which signs people actually used and where to spend print budget next time. See our guide on how to track QR code scans for details.
Frequently asked questions
Can I use QR codes as event tickets?
Ticket QR codes need a ticketing system that checks each code once at the door. Use a ticketing tool for entry, and Linkly codes for everything guests do once they're inside.
How far away can a QR code be scanned?
A simple rule: scanning distance is about 10 times the code's width. A 10 cm code scans from roughly 1 metre.
Can I change the link after printing the event signs?
Yes, if you used a dynamic QR code. Update the destination in your dashboard and every printed sign follows.
Do guests need an app to scan?
No. Every modern iPhone and Android phone scans QR codes with the built-in camera.
