Use case
QR codes for events
Event QR codes need to work under time pressure, with crowds, mixed lighting and visitors who may only scan once.
Good event QR codes reduce friction. They should point to mobile-friendly schedules, maps, registration forms or visitor information and be tested where people will actually scan them.
Concrete scenario
An event team prepares QR codes for registration, agenda pages, room maps, feedback forms and support contacts.
- Codes appear on signs, badges, handouts and presentation screens.
- Visitors may scan while walking or standing in a queue.
- Network conditions can be weaker than during planning.
Typical mistakes
Event QR codes often fail because the environment changes between design and use.
- The code is sized for a desk, not for a sign across a hallway.
- The destination is not mobile-friendly.
- WiFi or mobile reception is poor near the sign.
- The printed code is placed too low, too high or behind glass.
Recommended settings
Use large, high-contrast codes and stable targets.
- Use SVG for signs and posters.
- Use short, stable URLs for agenda and map pages.
- Increase size for long scan distances and crowded areas.
- Keep backup short links or printed fallback information for critical flows.
Test checklist
Run an event-context scan test before doors open.
- Scan from the expected queue or walking distance.
- Test in venue lighting, including low-light areas.
- Open the destination on mobile data and event WiFi.
- Check every printed sign after installation.
Example workflow
Prepare stable agenda and map URLs, create QR codes locally, export SVG for signage, print proofs, install test signs and scan them from the real visitor path.
