An event QR is the connective tissue between the printed program and the digital experience: scan the badge for an attendee's LinkedIn, scan the program for the live agenda, scan the booth banner for the sponsor's whitepaper.
Generate one for free below. No subscription, no signup, no expiry on the printed wristbands or banners. Static QRs encode the URL directly — they don't break if the dynamic-link provider goes dark mid-event.
The QRs an event actually needs
Attendee badge: each badge prints a unique QR encoding the attendee's vCard or a profile URL. Networking gets dramatically smoother — handshake, scan, contact saved, move on. Sessions can scan badges at the door for headcount.
Program QR for the live agenda: print the program PDF with a QR on the cover pointing at the always-current online agenda. Last-minute room changes don't require reprinting the program.
Session-specific QR: each room or session has its own QR for slides, links, or post-session survey. Attendees grab the materials before they forget to.
Sponsor booth QR: lead capture. Attendee scans, lands on the sponsor's gated content. Better signal than a fishbowl full of business cards, and the sponsor knows immediately who's interested.
Production logistics
Badges: laser print at 600 DPI on white card stock. QR size 2.5 cm × 2.5 cm on a name-badge holder. Pure black on white; ignore the urge to add brand color over the QR.
Programs: print QR on every spread, not just the cover. Attendees grab the program from random tables — they shouldn't have to flip back to find the agenda link.
Sponsor booth pop-ups: 8 cm × 8 cm QR at standing-scan height. The booth banner is read from 1–3 meters; smaller QRs lose at that distance.
Don't use a free dynamic-QR service for a printed conference program. If the redirect breaks during day-one keynote, hundreds of attendees hit a 404 simultaneously. Static QRs encode the URL directly — there's nothing to break.
Privacy and consent on attendee badges
If the badge QR encodes a vCard with the attendee's personal phone or email, get explicit consent at registration. Some attendees prefer not to broadcast contact details on a scannable badge worn around the venue.
An alternative: encode a per-attendee URL like conference.com/a/abc123 that resolves to a consent-gated profile. The attendee controls what shows up when scanned.
After the event, you have a choice: leave the URLs live as a permanent attendee directory, or sunset them. State the choice in the registration ToS so attendees know in advance.
Recommended QR types for this use case
- Attendee vCard — Each badge encodes a unique vCard. Scan saves it to contacts. (vCard)
- Live agenda URL — Print on program covers. Always-current agenda even after print. (URL)
- Session materials URL — Per-session QR for slides, recordings, post-session survey. (URL)
Frequently asked questions
- Should each badge have a unique QR or the same one?
- Unique — that's the entire value of a badge QR. Generate at registration as part of badge printing. We don't yet support bulk QR generation in the UI, but the route is on the roadmap.
- Does the QR work offline?
- The scan itself works offline — the camera reads the QR with no network. The URL or vCard the QR encodes works according to its kind: vCard saves to contacts offline; a URL needs internet to open the page.
- What happens to badge QRs after the event ends?
- They keep scanning, since they're static. The URL or profile they point at is your decision. Common patterns: leave the agenda online as a permanent record, sunset attendee profiles after 30 days, or migrate them into a permanent alumni directory.
