How to check in attendees quickly at the door.
To check in attendees quickly, open enough scanning lanes for your busiest half hour, put a scanner on every door staff member’s phone, ask guests to have their QR code open before they reach the front, and check groups in together. Most door delays come from three things: too few lanes, a bad connection, and staff who are seeing the scanner for the first time when the queue is already down the street. All three are fixable before doors open.
How many people do you need on the door?
Work from your peak, not your total. Most of your crowd turns up in a short window, often the 30 to 45 minutes after doors open or just before the headliner. A scan takes a few seconds, but the full exchange (bag check, wristband, a question about the cloakroom) is closer to 10 to 15 seconds per person.
A rough rule we use: one scanning lane for every 150 to 200 people you expect in that peak window, plus one floater who handles problems so the lane keeps moving. Put the problem cases (wrong date, can’t find the email, guest list) to one side. One confused guest at the front of a single lane holds up everyone behind them.
Can you use phones as ticket scanners?
Yes. You don’t need dedicated hardware. On Jamrats, door staff scan QR tickets with the Jamrats Organizer app on iOS or Android, or with the browser scanner at /scan if someone can’t install the app. Any modern phone with a camera works, and several people can scan the same event at once.
Set it up the day before, not at the door. Add your door staff with door-only access, so they can scan tickets without being able to edit the event or see your orders. Have each of them sign in, open the event and scan a test ticket. Ask them to bring a charged phone and a power bank. Scanning all night with the camera on drains a battery faster than people expect.
How do you handle groups, duplicates and screenshots?
Groups slow a line down when one person bought for five and everyone stands around while they scroll. With Jamrats, staff can scan one ticket from a multi-ticket order and check in the whole group together. Each ticket has its own number, so you can see how many from that order are already inside.
Duplicate scans are flagged straight away with an “already checked in” message. That covers the forwarded screenshot and the friend trying to reuse a ticket. Have the floater deal with these so the lane doesn’t stop while someone argues.
One problem that catches people out is a ticket email with several QR codes visible on one screen. A fast scanner can pick up the wrong one. The Jamrats scanner freezes on each scan and asks staff to confirm when more than one code is on screen, so the ticket being admitted is the one in front of them.
Do you need internet to scan tickets?
Yes. Jamrats scanning, in both the app and the browser, needs an internet connection to check each ticket. There is no offline mode, so plan the connection like you plan the sound.
Basements, packed rooms and old buildings often have poor mobile signal, and venue Wi-Fi can slow to nothing once a few hundred phones join it. Walk the entrance on a busy night beforehand and test a scan where the door will actually be. Bring a mobile hotspot on a different network from your staff phones, charged and ready, so you can switch quickly if the main connection drops.
A quick before-doors checklist
Remind buyers about their tickets. Jamrats sends a day-before reminder email, and anyone who can’t find their ticket can recover it by email at /find-tickets. Put that link on a sign by the queue.
Then, an hour before doors: every scanner signed in to the right event, a test scan done at the entrance, phones charged, the backup hotspot on, and the floater briefed on refunds, guest list and lost tickets. Our first event checklist covers the rest of event day.
