Event Check-in QR Code Generator — Free
Quick Answer
Create event check-in QR codes by generating unique QR codes per attendee in QRCrack's bulk QR generator — each encoding an attendee ID or check-in URL. Email QRs to attendees before the event. At the door, staff scan with any QR app and check off in a spreadsheet or check-in app.
Everything You Need to Know
QR code check-in replaces physical ticket queues with smooth, contactless entry. Attendees receive a unique QR in their confirmation email. At the door, a volunteer scans each QR in seconds — entry times drop by 60–80% compared to manual name list checks.
For simple events, a Google Form submission confirmation with a unique ID is all you need. Bulk-generate QR codes from those IDs in QRCrack and embed in confirmation emails. At the door, scan and mark off in Google Sheets.
Event platforms like Eventbrite, Hopin, and Townscript generate check-in QR codes automatically and provide scanning apps. QRCrack is the right tool for custom event systems, pop-ups, and community events where a full platform is overkill.
One check-in QR per attendee prevents gate-crashing. Each QR is unique and can be marked as 'used' — subsequent scans of the same QR alert staff to a duplicate entry attempt.

Frequently Asked Questions
How do I send check-in QR codes to attendees?
Generate unique QR codes in QRCrack bulk generator, then embed each PNG in a personalized confirmation email via Mailchimp, Brevo, or a mail merge tool.
What app do staff use to scan check-in QR codes?
Any free QR scanner app works for reading the QR content. For marking attendees as checked-in, a Google Sheet with QR content matched to attendee list works simply. Dedicated apps like zkipster or Eventzilla offer full check-in management.
Can the same QR be scanned twice?
The QR itself has no 'memory.' To prevent reuse, track scanned IDs in a database or spreadsheet and alert on duplicates — this requires a backend system or a dedicated check-in app.
What if an attendee does not bring their QR code?
Keep a backup name list. Good check-in systems have a manual lookup option for attendees who forget their QR.
