How do QR code and barcode wristbands work for event check-in?
Each band is printed with a unique QR code or barcode that staff scan at entry with a phone or scanner; the code ties to your attendee list so each band checks in once, which stops pass-backs and counterfeits.
How the flow works
You supply the attendee data (or just a count), each band gets a unique code, and staff scan at the gate for an instant valid-or-duplicate response. No special hardware is required - phones scan QR codes natively.
QR vs barcode
QR codes scan faster from phone screens and at angles, and store more data. One-dimensional barcodes work with inexpensive laser scanners and suit simple ticket-style workflows.
Add-ons that pair well
Sequential numbering as a visible backup, full-color branding, and tear-off stubs for raffles or drink tickets all combine cleanly with scannable codes.
When to skip scannables
For events under roughly 200 guests where visual admission control is enough, plain numbered Tyvek is cheaper and simpler.
