Get every guest through the door in under five seconds

Doors open at six. By six fifteen you have a line out to the car park, three staff staring at a laptop, and a sponsor asking why their VIP is standing in the rain. Check-in is where a well-run event either feels effortless or falls apart in front of everyone.
The fix is not more staff. It is a faster scan and a list that is ready before anyone arrives.
Measure the real number
Five seconds per guest sounds slow until you watch a desk that takes thirty. Someone searches a spreadsheet by name, spells it three ways, finds a duplicate, picks the wrong one, then writes a tick in a paper column. Multiply by four hundred guests and you have lost the first hour of your event.
The number that matters is time per guest at the busiest minute, not the average. Plan for the surge, because everyone shows up in the same fifteen minutes.
Scan, do not search
A QR code on the ticket turns check-in from a search into a confirmation. Point the camera, the guest record appears, you mark them in. The scan does the lookup, so staff are not typing names while a queue builds.
A good scan flow tells the person at the desk three things instantly:
- Is this ticket valid and not already used?
- Who is this, and what tier or table are they?
- Is there anything I need to do, like hand over a specific badge or escort a VIP?
If the answer to any of those takes a second look, the door slows down. Put the important flag on the screen in plain language, not buried in notes.
Catch the duplicate scan
People forward tickets. A guest sends theirs to a friend, both arrive, both scan the same code. The desk should catch the second scan and say so clearly, without accusing anyone. Already checked in at 6:04 is enough. The staffer decides what to do next; the system just stops two people walking in on one ticket.
Work offline, because the venue will
Hotel ballrooms, exhibition halls, and tented venues all share one trait: the wifi dies the moment four hundred phones join it. Check-in cannot depend on a live connection. The guest list lives on the device, scans record locally, and everything syncs when the signal returns. A door that stops working when the network blinks is not a door you can trust.
Print the badge at the desk, not the week before
Pre-printed badges sorted into alphabetical boxes are a tax you pay twice: once when you print names that never show, and again when you cannot find the box for a walk-in. On-demand badge printing at check-in means the badge is correct because it prints from the record you just scanned. Walk-ins, name changes, and last-minute VIPs all get a clean badge in seconds.
A queue is just a question the desk is answering too slowly. Make the answer instant.
Set up the desk like you mean it
The hardware around the scan matters as much as the scan:
- More lanes than you think you need. Two slow lanes beat one fast one.
- A separate VIP or protocol lane so a delegation never queues behind general admission.
- Chargers and a battery for every device. A dead tablet at minute twenty is a disaster.
- A printed fallback list, because belt and braces costs nothing and saves the night.
What diggri does at the door
diggri check-in scans the same QR you issued at registration, works offline, flags duplicates, and prints the badge on the spot. The desk sees the guest, the tier, and any protocol note in one glance. The number we care about is the one your guests feel: time from camera to handshake. Keep it under five seconds and the door disappears, which is exactly what a good door should do.
