QR codes for trade shows and conferences
The booth-QR triangle
Three QR placements compound:
- Booth backdrop QR — large (30cm+), points at a 'request a demo' lead form. Captures passive interest from passers-by.
- Rep badge QR — vCard format, lets attendees one-tap save the rep's contact instead of exchanging cards.
- Giveaway QR — printed on the swag (sticker, USB stick, etc.) routing to a content download or a discount-code redemption page.
Why dynamic + UTM is essential at trade shows
Use dynamic QRs with UTM parameters baked in: utm_source=trade-show, utm_campaign=expo-2026. Your CRM knows every captured lead came from this specific event — attribution that's impossible with static QRs.
Bonus: scan analytics tell you exactly when foot traffic peaks. If 80% of your scans happen between 10am-12pm, post a rep there at all times.
Sizing for booth backdrops
Trade-show booths are scanned from 2-4m. Backdrop QRs need to be much larger than typical:
- 20cm × 20cm — minimum for backdrop scanning at 2m
- 30cm × 30cm — recommended for backdrop scanning at 3m
- 40cm × 40cm — for trade-show floors with 4m+ aisles (large industry expos)
- Always print on matte vinyl — booth lighting causes glare on glossy finishes
Frequently asked
Should the booth QR go to a generic site or a campaign-specific landing page?
Always a campaign-specific landing page. Generic homepages convert at 1-3% from cold trade-show traffic; campaign-specific pages with the event name, the rep's photo, and a clear 'book a demo' CTA convert at 8-15%.
What's the best lead-capture form length for trade shows?
Three fields max: name, email, company. Trade-show attendees scan in passing — every additional field cuts completion by ~20%. Get them in your CRM with the basics, send a follow-up email with the full qualification questions later.
