Badges are the one piece of print every attendee carries from the first coffee to the last session. That makes them a natural home for a QR code, though it helps to be clear about what the code is for. A dynamic code from this tool works best as a shared code printed on every badge, opening an attendee hub, the schedule, the venue map, or the Wi-Fi details.
Unique per-person codes for lead scanning or access control need a dedicated event platform. A shared dynamic code, by contrast, is simple to set up and can change role during the event: an orientation page on day one, the agenda on day two, a feedback form at the end. Badge printing is often done at the last minute, but the code design can be locked in early.
Where to place it
- Back of the badge, so the front stays clean for name, company, and role, and attendees can flip it to scan.
- Bottom of the front side, below the name, on single-sided badges, with a short label underneath.
- On the lanyard card insert for double-sided holders, with Wi-Fi details printed next to the code.
- On speaker badges, linking to a speaker-only page with green room location, schedule, and AV contact.
- On exhibitor badges, opening a page with booth setup times, loading dock directions, and wristband rules.
Tips that improve scans
2.5 cm minimum
Badges are scanned at close range but often while swinging or tilted. A code of about 2.5 to 3 cm square, printed in solid black on white, is a safe size.
Label it clearly
Badge codes get mistaken for personal ID or lead-scanning codes. Print a short label like "Schedule, map & Wi-Fi" so attendees know it opens shared information.
Avoid lamination glare
Glossy plastic holders reflect overhead lights. Choose matte sleeves where possible, and test-scan through the actual holder under conference-hall lighting. If scans fail, tilting the badge slightly usually helps, so mention that at the help desk.
Keep space for names
Long names and job titles grow unexpectedly. Fix the code's position in the template and test with the longest name on your list before printing all badges.
Badges outlive a schedule overhaul
A trade association prints 1,200 badges a week before its annual conference, with a code on the back linking to the attendee hub. Two days out, the organizers move the event app to a different provider and the hub's address changes. Instead of reprinting badges, they redirect the code to the new hub. On the last afternoon they switch it again to the feedback survey and mention it from the stage, so the badges help collect responses too.
