How to Use QR Codes for Events: Tickets, Schedules & Check-ins

QR codes have become the connective tissue of modern events. Attendees scan to check in, access schedules, join Wi-Fi, leave reviews, and follow social accounts — all without staff handing over anything physical.

This guide covers the most effective ways to use QR codes at events, and how to generate each type for free.

1 — Event Check-In QR Codes

The most common use: a unique QR code per ticket that staff scan at the door.

How it works for free events:

1. Create a Google Form or Tally form for RSVP
2. Respondents get a confirmation email with a confirmation URL
3. Encode that URL as a QR code — one per registrant
4. Staff scan at entrance; the form response is marked as attended

For paid events, platforms like Eventbrite and Luma generate QR tickets automatically. For DIY events, this approach costs nothing.

What to put in the QR code: A unique URL that identifies the attendee — even a Google Sheets row URL with a pre-filled form works.

2 — Digital Schedule / Programme

Print a QR code on badges, programs, or door signage that links to the event schedule.

Benefits:

• Update the schedule any time without reprinting
• Link to session recordings after the event
• Works as a live agenda during the event (e.g. a Notion page or Google Doc)

Best hosting options for schedules:

Use a Notion or Google Doc for the schedule so you can fix typos or add last-minute changes without regenerating the QR code.

3 — Venue Wi-Fi Access

If your event is at a venue with Wi-Fi, print a QR code on each table or badge so attendees can connect without hunting for a password.

See our guide: How to Create a Wi-Fi QR Code

Tip: Put the Wi-Fi QR on the back of the event badge — it's always within reach.

4 — Speaker / Sponsor Profiles

A QR code on a speaker's slide deck or sponsor banner that links to:

• Speaker bio + LinkedIn
• Sponsor website or special offer landing page
• Product demo video

Generate one URL-type QR code for each speaker or sponsor. Customizing the color to match each sponsor's brand takes 30 seconds with the color picker.

5 — Post-Event Feedback

Collect feedback on the spot while the event is fresh. A QR code at the exit linked to a Google Form or Typeform beats emailing a survey three days later.

Placement ideas:

• Exit doors or checkout tables
• Final slide of every presentation
• Back of the badge
• Printed on any takeaway materials (lanyards, tote bags, notebooks)

6 — Social Media / Community Follow

Conference attendees are exactly the audience you want on your socials. A QR code at registration, on badge backs, or on signage can link to:

• Instagram profile
• LinkedIn company page
• WhatsApp community group
• Newsletter signup

For WhatsApp, use the WhatsApp QR code generator to encode a direct chat link.

Printing Tips for Event QR Codes

Always test-scan a printed copy before the event. Print a test sheet, scan it at arm's length, and confirm the destination URL is correct.

---

Common Mistakes to Avoid

• Linking to a page that requires login — attendees can't access it
• Using a URL that will expire — check your hosting platform's link expiry
• Making the QR code too small to scan — follow the size guide above
• Light QR on light background — always use dark on white for reliable scanning
• Not testing before the event — scan from multiple phones before printing in bulk
