Each attendee receives a unique QR code (typically by email or in an event app). At the venue, staff or self-service kiosks scan the QR with any smartphone. The system validates the ticket and logs attendance in real time. For simple events, a URL-based QR linking to an RSVP page or check-in form works effectively. For conference-level operations, this integrates with platforms like Eventbrite, Cvent, or Whova.

For small events under 100 attendees, create a Google Form as your check-in confirmation page. Generate a URL QR code pointing to the form. When entry staff scan attendees' personal QR codes (generated per-registrant), names are captured in real time in a Google Sheet. For public events with no individual codes, a single entry QR code can direct all attendees to a landing page with event information, schedule, and emergency contacts.

Speed: QR scanning processes one person per second vs 10–30 seconds for manual list lookups. Environment: Eliminates paper printing for thousands of tickets. Accuracy: Digital records replace manual tick sheets. Security: Unique per-attendee QR codes prevent ticket duplication (using a proper event platform). Data: Precise attendance tracking including timestamps and entry points.
