The scanner app is what your door staff use to check attendees in. It reads the QR code on an attendee’s ticket, confirms the ticket is valid for that event, and records the check-in. Every ticket scanned counts toward the Tickets Scanned figure on your dashboard, so you can watch arrivals in real time from anywhere. The check-in record is also your protection against ticket reuse. Because each scan is recorded, the same QR code can’t be waved through twice — the second attempt comes back as already scanned. That only works if the door actually scans every ticket, so brief the team: no scan, no entry, even when the queue is long and the ticket “looks fine”.

​
Getting access

Access flows from the organizer’s side, not the scanner’s — a scanner can’t sign themselves up. Their account, role, and event list all come from an admin, which is why a scanner who “can’t get in” is almost always fixed in Settings → User & Role rather than on the device.
1

The organizer adds the scanner

An admin invites them with the Scanner Plus role and assigns them to specific events. See Add a scanner.
2

The scanner receives an email invitation

TixFix emails the address the admin entered, with instructions for getting into the scanner app.
3

They sign in

They use the email address the invitation was sent to.
4

They select the event

Only events the admin assigned to them are available. If an event is missing, the admin needs to add it to their Select Events list.
Run this whole chain before event day. An invite that landed in spam, a typo’d email address, or a missing event assignment are all five-minute fixes in the afternoon and a blocked entrance at 7pm.
Setup instructions for getting the scanner app onto a specific device are being finalized for these docs. If your door team needs to be set up before then, email contact@tixfix.ai and we’ll get them running.

Scanning a ticket

Screenshot coming soon. This flow needs a live order or a device we could not reach when these docs were captured. The steps below are written from the product as it behaves today; the illustration will follow.
Point the device camera at the QR code on the attendee’s ticket. The ticket may be on a phone screen or printed; both work. The result is one of three things: The three results deserve three different tones at the door. Valid is the overwhelming majority — wave them through. Already scanned is usually innocent, and how to handle it is worth deciding in advance. Invalid most often means the wrong night or the wrong venue, not fraud — ask before refusing. An attendee who can’t find their ticket at all is a different problem from a ticket that won’t scan. Their ticket can be sent again — see Resend a ticket — which is faster than debating at the front of a queue.

​
Questions at the door

If the organizer marked a registration question as shown when scanning, the attendee’s answer appears when their ticket is scanned — meal choice, drink package, session track. Scanners should know before doors open which answers to expect and what to do with each one — the app shows the answer, but the action is yours to define. See Questions at check-in for how these are set up and what makes a good door-facing question.

Advice for the door team

  • Get set up before doors open. Sign in, select the event, and test-scan one ticket while there’s no queue. This catches sign-in and event-assignment problems while they’re still cheap.
  • Brief staff on “already scanned”. It’s usually a duplicate screenshot or a re-entry, not a fraud attempt. Have a rule ready — improvising a policy in front of an unhappy attendee never goes well.
  • Keep devices charged. Scanning runs the camera continuously and drains batteries fast. A charger at the door costs nothing; a dead device mid-queue costs you the queue.
  • Have a fallback. Know who to call if a device fails mid-queue, and make sure at least one admin is reachable during doors — some fixes, like adding an event to a scanner’s list, only an admin can make.
Quick answers to the questions that come up on the night are in the Scanning FAQ.
