Why a QR code works so well for conferences
Conferences are a high-volume, low-follow-up business. Exhibitors collect a stack of 200 paper cards, transcribe maybe 30, and follow up with five. A QR turns that pipeline upside down — the lead enters your CRM at the moment of scan, with consent baked in.
- Lead capture with consent — attendees scan, share contact, and you have GDPR-compliant data with a timestamp.
- Faster than paper cards — no scanning, no transcribing, no losing them in the swag bag.
- Direct CRM integration — the form pipes straight to HubSpot, Salesforce, Pipedrive, or Mailchimp via Zapier.
- Works for every role — exhibitors capture leads, speakers share contact, networking attendees skip the awkward LinkedIn typing dance.
- Trackable post-event ROI — scan counts per booth, per lanyard, per swag piece reveal what actually worked.
Generate your conference QR in 5 steps
Decide: vCard QR (simple contact) or URL QR (lead-capture form)
Pick vCard for casual networking — attendees save your contact instantly. Pick URL for booth lead capture — link to a form that drops into your CRM with a consent checkbox.
For vCard, fill in name, title, company, email, LinkedIn — keep under 1 KB
Open the vCard generator and add name, title, company, email, mobile, and LinkedIn URL. Keep total data under 1 KB so the QR stays scannable from arm's length.
For lead form, build a Typeform/Google Forms with email capture
Build a 3-field form: name, email, interest tag. Add a GDPR consent checkbox at the bottom. Connect to HubSpot, Salesforce, or Mailchimp via Zapier — leads land in your CRM in real time.
Generate the QR and print on lanyard, badge, booth backdrop
Print at the right size for the surface: 4×4 cm for lanyards, 8×8 cm for badges, 30×30 cm for booth backdrops visible from 5 m away.
Add a "Scan to connect" caption
A clear caption — "Scan to connect" or "Scan to share contact" — doubles scan rates. Place it directly below the QR in 12-16 pt sans-serif. Multilingual is a plus for international events.

Best practices for conference QR codes
- Use a lead-capture form for B2B — it collects email and interest tags, where a vCard only shares yours.
- Integrate with HubSpot, Salesforce, or Mailchimp via Zapier — leads land in your CRM in real time, not in a spreadsheet a week later.
- Send post-event follow-up within 24 hours — leads go cold in 48 hours. Automate the first email with the lead's interest tag prefilled.
- Test booth QR scans from 3 m distance — minimum QR size = scan distance ÷ 10. Always test before the event opens.
- Include a GDPR consent checkbox — required for EU events, good practice everywhere.
- Use matte finish on printed QRs — booth lighting reflects off glossy surfaces and breaks scans.
Common mistakes to avoid
- Tiny QR codes on booth backdrops — 5 m visibility means 30+ cm minimum QR size. A 10 cm QR on a 3 m backdrop is unscannable.
- No follow-up automation — leads go cold in 48 hours. Manual follow-up two weeks later is wasted budget.
- Forgetting GDPR consent on EU events — fines start at €20K and escalate. A consent checkbox costs nothing.
- Using a personal vCard for company purposes — it looks unprofessional and confuses the lead about who they're connecting with.
Frequently asked questions
vCard vs lead-capture form — which one should I use?
vCard for casual networking and individual attendees — it's instant and friction-free. Lead-capture form for booth exhibitors who need email + interest tags + CRM integration. Many companies use both: a personal vCard on the lanyard and a lead form on the booth backdrop.
Can I have multiple QR codes for different things?
Yes, and you should. One on your lanyard for personal contact, one on the booth for company lead capture, one on swag for post-event follow-up. Each with separate UTM tags so you know which channel converted.
Can I track how many people scan?
Yes. Use a URL QR pointing to a lead form with UTM parameters, or a dynamic QR with built-in scan analytics. Pure static vCards cannot be tracked, but you can compare LinkedIn add rates as a proxy signal.
Will scans work from across a booth backdrop?
Only if the QR is large enough. Rule of thumb: minimum QR size = scan distance ÷ 10. For 5 m booth backdrops, print at 50 cm. For 3 m, 30 cm. Add high contrast and matte finish for guaranteed scans.
Can I add GDPR consent to the QR flow?
Yes — and you must, for EU events. Use a URL QR linking to a lead form with a clearly worded consent checkbox above the submit button. Store the consent timestamp alongside the lead in your CRM.
What CRM integrations work with this?
Any tool with a webhook works. HubSpot, Salesforce, Pipedrive, Mailchimp, ActiveCampaign — all integrate via Zapier or native webhooks. The QR points to your form; the form pipes to your CRM. No custom code needed.
Is this QR code generator really free, with no catch?
Yes — free forever. No sign-up, no watermark, no usage limits, no expiry. The entire generator runs in your browser, so we have no server costs to recover. No premium tier exists.
Will my QR code expire or stop working?
No. Static QR codes (which this site generates) never expire — they encode the destination directly into the image. The QR works as long as the URL or content it points to is still valid. Print once, scan forever.
Can I track how many people scan my QR code?
Not from the QR itself (static codes have no built-in analytics). The simplest workaround: add UTM parameters to your destination URL (e.g. ?utm_source=qr&utm_campaign=flyer) and read scans in Google Analytics, Plausible, or your site's log files.
What's the minimum print size for a QR code to scan reliably?
Rule of thumb: 2×2 cm (0.8") for cards and stickers, 5×5 cm for table tents and posters, 30×30 cm for billboards. The 1:10 ratio works: scan distance ≈ QR size × 10. Always test scan at actual size before printing a large batch.
Can I edit where the QR points after it's printed?
Not directly — static QR codes have the destination baked in. Workaround: point your QR to a short URL on your own domain (e.g. yourdomain.com/menu) that redirects to the real destination. You can change the redirect target any time without reprinting.
