QR Codes for Events & Ticketing: The Complete Check-In Guide (2026)
QR codes have transformed event management. From conferences to concerts, festivals to fundraisers — a simple scan replaces paper tickets, speeds up check-in lines, and gives organizers real-time attendance data. Here is everything you need to know about using QR codes for events and ticketing.
Why Use QR Codes for Event Ticketing
Paper tickets get lost, counterfeited, and slow down entry lines. QR code tickets solve all three problems while giving you data that paper never could.
Instant check-in
A phone scan takes under 2 seconds. Paper ticket verification takes 15-30 seconds. At a 500-person event, that is the difference between a 20-minute line and a 2-minute line.
Zero counterfeiting
Each QR code is unique and can only be scanned once. Dynamic QR codes can even rotate their content, making duplication impossible.
Real-time attendance tracking
Know exactly how many people have arrived, peak entry times, and no-show rates — all updated live on your dashboard.
No printing costs
Attendees keep their ticket on their phone. No physical tickets to design, print, or ship. Saves money and the environment.
Easy updates
Venue changed? Time shifted? With dynamic QR codes, update the linked information without reissuing tickets.
Contactless experience
No physical exchange needed. Attendees show their screen, staff scan it, done. Faster, safer, more hygienic.
Types of QR Codes for Events
Not all event QR codes serve the same purpose. Choose the right type based on what you need.
Ticket verification QR codes
Each attendee gets a unique QR code linked to their ticket ID. At the door, scanning validates the ticket and marks it as used — preventing re-entry or sharing.
Best for: paid events, concerts, conferences
Event information QR codes
Link to a landing page with the full event schedule, venue map, speaker bios, or WiFi details. Place these on posters, programs, or table cards.
Best for: conferences, trade shows, weddings
Registration QR codes
Point to a signup form where attendees can register on the spot. Great for walk-ins at free events or for collecting leads at booths.
Best for: free events, workshops, networking meetups
Feedback QR codes
After the event, direct attendees to a survey or review form. Print them on exit signs or include in follow-up emails.
Best for: post-event surveys, session ratings, NPS collection
How to Set Up QR Code Ticketing
Getting started with QR code tickets is straightforward. Follow these steps to go from zero to scanning in under 30 minutes.
Use a QR code generator like QR-Verse to create dynamic QR codes. Dynamic codes let you track scans and update the destination URL without changing the code itself.
For paid events, generate one QR code per ticket. The code should resolve to a verification endpoint that checks the ticket ID against your database.
Include the QR code prominently — at least 3 cm wide. Add the event name, date, time, and venue. Keep it clean so the code is easy to scan.
Send tickets as PDF attachments or direct links. Most attendees will screenshot the QR code or save the PDF to their phone.
Any smartphone with a camera works as a scanner. For higher throughput, use dedicated QR scanner apps or tablets mounted on stands.
Scan every ticket type in different lighting conditions. Test with cracked screens, low brightness, and printed codes. Fix issues before attendees arrive.

Create Event QR CodeCheck-In Best Practices
A smooth check-in experience sets the tone for your entire event. These tips keep lines short and attendees happy.
Event Types That Benefit Most
QR code ticketing works for events of all sizes, but some formats benefit more than others.
Music festivals & concerts
Handle thousands of check-ins per hour across multiple gates. QR codes eliminate ticket scalping when combined with ID verification.
Corporate conferences
Track session attendance, manage VIP access, and collect lead data at sponsor booths — all through QR scans.
Charity galas & fundraisers
Link QR codes to donation pages. Place them on table cards so guests can contribute during the event with a quick scan.
Workshops & classes
Cap attendance with limited QR code tickets. Track who actually showed up versus who registered to improve future planning.
Sports events
Manage season passes with rotating QR codes that change each game day. Integrate with food and merchandise for a cashless experience.
Trade shows & expos
Badge QR codes let exhibitors scan visitors to capture leads. Attendees scan booth codes to collect digital brochures.
Security & Anti-Fraud Measures
QR code tickets are inherently more secure than paper, but smart implementation makes them nearly bulletproof.
One-time scan validation
Mark QR codes as "used" after the first scan. Any duplicate scan triggers an alert and denies entry.
Dynamic QR codes
Unlike static codes, dynamic QR codes can be updated or deactivated remotely. If a ticket is refunded, instantly invalidate the code.
Encrypted payloads
Encode ticket data with encryption so the QR code content cannot be read or replicated by third-party scanners.
Time-limited validity
Set QR codes to expire after the event start time. A code for a Saturday concert should not work on Sunday.
ID matching
For high-value events, link each QR code to an attendee name. Check ID at the door to prevent ticket resale.
Audit trail
Log every scan attempt — successful or not. This data helps identify fraud patterns and improve security for future events.
Event Analytics from QR Code Data
Every QR code scan generates data: timestamp, device type, approximate location, and whether the scan was successful. For event organizers, this is a goldmine of operational intelligence.
Track peak arrival times to optimize staffing. See which entrance gates are busiest to redistribute volunteers. Measure no-show rates accurately — if 1,000 tickets were issued but only 750 QR codes were scanned, you know exactly where you stand.
Post-event, analyze scan patterns to improve future events. Did most people arrive in the first 30 minutes or trickle in over 2 hours? Which sessions had the highest badge scan rates? This data drives better decisions for your next event.
Common Mistakes to Avoid
QR codes too small on tickets
Codes smaller than 2.5 cm are hard to scan, especially from phone screens with cracked glass or low brightness. Go bigger.
No offline fallback
Venue WiFi crashes when 500 people connect simultaneously. Always have an offline-capable scanning solution ready.
Using static instead of dynamic
Static QR codes cannot be tracked or deactivated. For any event with paid tickets, always use dynamic codes.
Forgetting the quiet zone
Placing the QR code edge-to-edge against a colorful background makes scanning unreliable. Maintain a white border around the code.
No test run
First-time scanning on event day is asking for trouble. Always do a full dry run with real devices 24 hours before.
Ignoring accessibility
Not everyone has a smartphone. Provide a print-at-home option and have manual lookup available for attendees who cannot scan.

Get Started FreeFrequently Asked Questions
Are QR code tickets free to create?
Yes. QR-Verse lets you create dynamic QR codes for free, including scan tracking. You can generate individual codes for each attendee without paying per ticket.
Can QR code tickets be scanned offline?
Yes, if you download the attendee list to your scanning device beforehand. The QR code itself is just data — it does not require internet to be read. Validation against a database does need connectivity, but offline mode with pre-loaded lists works.
How do I prevent ticket duplication?
Use dynamic QR codes with one-time scan validation. Once a code is scanned at entry, it is marked as used. Any subsequent scan of the same code triggers a duplicate alert and denies entry.
What if an attendee loses their QR code?
Have a manual lookup system at the door — searchable by name or email. You can also resend the ticket QR code via email from your event management dashboard.
Can I track how many people attended?
Absolutely. Dynamic QR codes log every scan with timestamps. Your dashboard shows total check-ins, arrival patterns, and no-show rates in real time.
Do attendees need a special app to scan their ticket?
Attendees do not need any app. They just show the QR code on their phone screen. Your check-in staff scans it with a smartphone camera, a dedicated scanner app, or a barcode scanner device.
How big should the QR code be on a digital ticket?
At least 3 cm when displayed on a phone screen. Ensure high contrast (dark code on light background) and avoid placing it over busy background images.
Can QR codes handle VIP and general admission differently?
Yes. Generate different QR codes for each ticket tier. Your scanning system reads the embedded tier data and routes attendees to the correct entrance or area.
