Tickets and Wristbands: The Gate Rush
Event tickets and wristbands are scanned at gates under time pressure — 15 to 25 cm, often in uneven outdoor light, by staff who need each scan to take under a second. Reliability here is operational, not cosmetic: a 1% failure rate at a 10,000-person gate is a hundred angry attendees and a queue that stops moving. Size for the worst gate conditions (bright sun, tired staff, old scanners), not the best.
The 10:1 Rule of Thumb
At 20 cm the rule suggests 20 mm; print tickets at 25 mm for margin, because gate scanning is hurried and imperfect. Wristbands are the harder case — the wearable area is small and curved — so 18–20 mm on the flattest panel, with the shortest possible payload doing the heavy lifting. In both cases, encode a short ticket token, never attendee details: density is the enemy of gate speed.
Recommended Size
Tickets: 25 × 25 mm (about 1 inch). Wristbands: 18–20 mm on the flat outer panel opposite the closure. On wristbands, the flat panel is small, so every millimeter counts — resist the urge to add decorative elements near the code, and keep the token short enough that the QR version stays low.
Substrate and Printing
Tickets print thermal or thermal-transfer on ticket stock; wristbands are Tyvek, vinyl, or silicone with thermal-transfer print. Tyvek survives sweat, rain, and multi-day festivals; paper wristbands don't — match the material to the event conditions honestly. Thermal-transfer (with ribbon) outlasts direct thermal for multi-day events; direct thermal is fine for single-evening use but fades and smudges with heat and moisture.
Placement and Practical Tips
- On wristbands, place the code on the flat panel opposite the adhesive closure, and keep it off the curve of the wrist — curvature foreshortens edge modules and the code is scanned while worn.
- Keep tear-off stubs and perforations away from the code; a stub torn through the quiet zone voids the ticket at the worst moment.
- Gate scanners are usually dedicated imagers, not phones — test with the actual gate hardware, in daylight and under floodlights, before doors open.
- Print a human-readable ticket number under the code as a fallback for manual entry when scanning fails.
- For festivals, print a spare batch: wristbands get lost, damaged, and swapped, and reprinting mid-event is chaos.
Common Mistakes
- Wristband codes printed on the curved section that sits on top of the wrist, where modules compress.
- Cheap direct-thermal wristbands that smudge into illegibility with sweat by mid-event.
- Encoding the entire order confirmation — long payloads make dense symbols and slow every gate transaction.
- No human-readable fallback, so a single scanner failure becomes a customer-service incident.
