How to run event check-in without a queue
Staffing, QR ticket scanning and offline fallbacks for getting a full house through the door without a queue down the street.
Published · Updated
A door jam is rarely a software problem. It is almost always too few scanners, no plan for the edge cases, or a venue basement with no signal. All three are solvable the week before, and none are solvable at 9 PM with a queue forming down the street and your headliner due on stage.
Staff the door to the arrival spike
People do not arrive evenly. Expect roughly half your audience in the busiest 45 minutes, usually just before the headline set. Size your door for that spike, not for average throughput. A practised scanner clears a ticket in five to eight seconds, so one scanning lane handles around 400 people an hour — assuming nothing goes wrong, which it will.
- Estimate your peak: about 50% of capacity inside the busiest 45 minutes.
- Divide by 400 per lane per hour, then add one lane as slack.
- Split ID checking from scanning. One person verifies age and ID, the next scans. Serial specialists beat parallel generalists at a door.
- Give every scanner the manual search fallback and one named person to escalate to.
Brief the team on the four things that go wrong
Door staff freeze on edge cases because nobody told them the answer. Decide these in advance and write them on a card each scanner keeps in a pocket:
- Duplicate scan. The app warns when a code has already been used. Assume an honest error first — a shared screenshot, a friend who already walked in — and use manual search to check the order before accusing anyone.
- No ticket on the phone. Search by name, email or phone in the app. The order exists even when the email does not.
- Wrong name on the ticket. Transferred tickets are legitimate; the token is what matters, not the name printed on it.
- Underage or wrong ID. This is a policy decision, not a scanner decision. Escalate to the named person and keep the lane moving.
Use complimentary tickets instead of a guest list
A paper guest list is a second, unscannable system that slows the fast lane down. Issue comps as real tickets to real email addresses and they scan exactly like everything else — artists, press, venue staff and plus-ones included. Your attendance numbers stay accurate too, which matters when you are settling with the venue.
Read the activity log while the door is still open
The check-in log updates live, so you can see scan rate and total admitted mid-event. A sudden drop usually means a lane has stalled, not that arrivals stopped. Check it 30 minutes into the spike; it is the difference between fixing a jam and hearing about it in reviews the next morning.
