Working the door

Anyone can work the door without an account. You send them a link, they open it on their phone, and that phone can scan for that one event and nothing else. It stops working when the event ends.

Venue wifi fails. When the scanner loses signal it carries on letting people in using the ticket number, saves each scan on the phone with the time it happened, and sends them all up when the connection returns. Checking a ticket offline is genuinely less strict than doing it online, so those scans are marked as offline rather than quietly treated as the same thing — and if someone got in twice during the gap, you will be told.

Phones die, and people book under a partner's email. The scanner can search your guest list by name and let somebody in with one tap, so a dead battery is a five-second problem rather than a queue. That search needs the box-office permission, which is granted separately from scanning — reading the whole guest list is a bigger thing than pointing a camera at a code.

You can also print the list. The door list is a sheet sorted by name with a box to tick, the table each guest is on, anything they still owe, and who has already been scanned. Some venues ask for paper and some nights want two queues; it is on the Doors tab of your event.

Add the scanner to a phone's home screen and it opens without the browser bar, which is about a hundred more pixels of camera.
