How to Use QR Codes for Event Tickets & Check-In
A practical guide to using QR codes for event registration, ticketing, and on-site check-in.
How QR Ticketing Works
Each ticket contains a unique QR code. Either embedded in a PDF, displayed in a mobile app, or printed on a physical ticket. At the venue, staff scan each QR code with a smartphone or dedicated scanner. The system validates the ticket, marks it as used, and prevents re-entry with the same code.
For small events, you can generate unique QR codes using our bulk generator and manually track check-ins. For large events, integrate with an event management platform like Eventbrite, Luma, or Ticket Tailor.
Setting Up QR Code Check-In
For DIY check-in: generate a unique code per registrant using our bulk QR generator with a CSV of attendee names or IDs. Print or email the codes to attendees. At the event, use any QR scanner app and cross-reference against your attendee list.
For professional events: most ticketing platforms generate QR codes automatically and provide a companion scanning app. The workflow is the same. The platform just handles the code generation and validation for you.
Best Practices for Event QR Codes
Ensure every QR code is unique. Duplicate codes allow multiple entries on a single ticket. Print codes large enough to scan quickly (1.5 inches minimum on a badge). Test your scanning workflow before the event with real devices under realistic lighting.
Have a backup plan. If WiFi fails at the venue, some scanning apps work offline. Print a backup attendee list. Technology enhances check-in but should not be a single point of failure.
