Check guests in with your phone camera

Turn any phone into a ticket scanner at the door — no app to install.

Every ticket TicketOtter sends has a QR code. On the night, you scan those codes with your phone's camera to check people in. There's nothing to install and no password to type on the phone.

Open the scanner

  1. On your computer, go to Events and press Check in on the event you're running. (It's also at the top of the event's own page.)
  2. Choose Scan QR codes.
  3. Point your phone's camera at the QR code on screen and open the link it finds. The scanner opens, already signed in to that event.

No computer to hand? Press Continue on this device to scan with the device you're on.

For an event with several dates, open the event and press Check in at the top of its page. You'll choose which date you're checking in first, and the scanner only accepts tickets for that date.

The scanner link works for 24 hours. After that, the scanner tells you it has expired: press Check in again on your computer for a fresh code.

Scan tickets

The first time, your phone asks to use the camera — tap Allow. Then point the camera at a guest's QR code, on their phone or a printout. You don't need to press anything.

You see What it means
Green — Checked in Let them in. Their name and ticket type are shown, and your phone buzzes once.
Amber — Already checked in This ticket has been used. Check the name matches the person in front of you.
Red Don't let them in yet. The reason is shown: a ticket for another event or date, a cancelled or refunded ticket, or a code that isn't a TicketOtter ticket.

Tap a result to clear it early. The count at the top shows how many people are in, and Recent scans lists who you've let in and when.

When a ticket won't scan

Tap Find by name, search by name, email or ticket reference, and tap Check in next to the right ticket. People who haven't arrived yet are listed first.

Tips for the door

  • More than one door? Scan the same code on each phone. Every scanner stays in step, so a ticket can't be used twice.
  • Quiet spell? Tap Pause so the camera doesn't read a code by accident, and Resume when the next guest arrives.
  • Dark venue? Tap the flash button, if your phone has one, or turn up the brightness on the guest's phone.
  • Camera not working? Make sure the browser is allowed to use the camera in your phone's settings, then tap Try again. Use the camera button to switch to another camera.
