USB & Bluetooth readers

Check-in app ·4 min read ·Updated June 2026
You're here because

you have a hardware barcode/QR reader and want the fastest possible scanning for a busy gate.

For high-volume entrances, a dedicated USB or Bluetooth reader is faster than a camera. The app supports them with no special setup.

How it works

Hardware QR/barcode readers act as a keyboard: when they scan a code, they “type” it and press Enter. The check-in app listens for that, so a scan drops straight into the manual entry box and submits automatically – read, beep, next.

Connect a reader

  1. Pair a Bluetooth reader to the phone/tablet, or plug a USB reader into a device that has a port (or a USB-OTG adapter).
  2. Open the check-in app and make sure the manual-entry box has focus – on desktop it’s focused automatically; on a phone or tablet, tap the manual-entry box once so the reader’s keystrokes land there.
  3. Scan a ticket – the code is entered and checked instantly, running the same rules as every other method.
Best of both: keep the camera available as a fallback for the occasional crumpled ticket the hardware reader struggles with.
