QR Codes for Events and Conferences

Events generate dozens of opportunities for QR codes — from registration to feedback to post-event follow-up. This guide covers the most impactful uses and how to implement them.

Event Check-In and Registration

The Problem

Paper check-in lists are slow. Manual name searches create lines. Typed URLs for digital registration are error-prone on mobile.

The QR Code Solution

Generate a QR code linking to your registration or check-in page. Display it at the entrance so attendees can scan and check in on their own phones.

What the QR code should link to:

• A mobile-optimized registration or check-in form
• An event app download page
• A ticketing platform check-in page

Placement:

• Printed on a standing banner near the entrance (15+ cm QR code)
• On a desk sign at the registration table (5–8 cm)
• Included in pre-event email so attendees can register before arriving

Sizing for Check-In

The entrance is busy. People scan from different distances. Use a larger QR code than you think you need:

• Banner or poster: 15 x 15 cm minimum
• Desk sign: 5 x 5 cm minimum
• Include “Scan to Check In” text above the code

Event Schedules and Programs

Instead of printing 500 paper programs that half the attendees lose, link to a digital schedule via QR code.

What to link to:

• A mobile-friendly web page with the schedule
• A shared Google Calendar
• A PDF schedule hosted online
• Your event app’s schedule section

Where to place it:

• Table tents on every dining table
• On the back of name badges
• On signage at each session room entrance
• On the screen between sessions

Advantage: if the schedule changes (speaker cancellation, room swap), you update the web page and the same QR code automatically shows the latest version.

Feedback and Surveys

Post-event surveys have notoriously low response rates. QR codes at the right moment can improve this significantly.

Strategy: place QR codes linking to feedback forms at the exit of each session, not just at the end of the entire event. People are most willing to give feedback immediately after an experience.

Where to place them:

• On screen during the last slide of each presentation
• Table tents at each table during the closing session
• On the exit doors of session rooms
• In the post-event thank-you email

What to link to:

• A short Google Form or Typeform (5 questions maximum for on-the-spot feedback)
• An NPS survey
• A session-specific rating form

Networking and Contact Sharing

QR codes make it easy for attendees to connect without fumbling with business cards or LinkedIn searches.

Speaker Contact Sharing

Speakers can display a vCard QR code on their final slide. Attendees scan to save the speaker’s contact details instantly.

Attendee Badges

Print a personalized QR code on each attendee’s badge. Options:

• Link to their LinkedIn profile
• Encode their vCard data
• Link to their profile in the event app

Digital Business Cards

Set up a station or encourage attendees to generate their own vCard QR code before the event. They can show it on their phone for others to scan.

WiFi for Venues

Conference venues often have complex WiFi credentials. A WiFi QR code on every table and at the registration desk saves hundreds of “What’s the WiFi?” questions.

Placement:

• Table tents on every table
• Registration desk signage
• Projected on screen before sessions begin
• Printed on the back of name badges

See our WiFi QR code guide for detailed setup instructions.

Sponsor and Exhibitor Engagement

QR codes give sponsors a measurable touchpoint:

• Booth banners — QR code linking to a product demo or special offer
• Sponsored materials — QR code on tote bags, lanyards, or swag linking to the sponsor’s landing page
• Sponsored sessions — QR code on screen linking to the sponsor’s content or free trial

This gives sponsors trackable engagement data (page visits from the QR code URL) rather than vague “brand visibility.”

Practical Production Tips

Print Multiple Sizes

An event uses QR codes at multiple distances:

• Close-up (badges, table cards): 2–5 cm
• Medium (desk signs, screens): 5–10 cm
• Far (banners, wall signs): 15+ cm

Generate the QR code once and export as SVG. Then scale to each size as needed. See best QR sizes by format for exact recommendations.

Test in the Venue

Venue lighting can be tricky — dim conference rooms, bright exhibition halls, mixed indoor/outdoor spaces. Print test codes and scan them at each location before the event day.

Use Short URLs

Event URLs tend to be long (events.company.com/2026/spring-conference/schedule). Use a URL shortener to create a clean link (company.com/schedule) before encoding it. Shorter data means a simpler, more scannable QR code.

Plan for Volume

If you expect 500 attendees, print 600 table cards (tables get messy, cards get taken, extras are needed). For badges, print the QR code as part of the badge template so it scales with your registration count.

Post-Event Use

After the event, QR codes can continue working:

• The feedback survey link remains active for late responses
• Session recordings can be added to the schedule URL
• Speaker contact QR codes still point to valid profiles
• Sponsor landing pages can transition to ongoing offers

Do not deactivate event URLs immediately after the event. Give attendees at least a month to revisit the resources.
