Event check-in app.QR code check-in in seconds.
The AirLST event check-in app for iOS and Android scans the QR ticket, shows the guest and marks them as checked in on your guest list, live at every station. Plus-ones, walk-ins, badge printing and real-time attendance are built in.
A check-in app that doesn't need a second list.
The app reads and writes the record you spent weeks preparing. No export for the door.
Scan, display, status: the guest is checked in before they've put their bag down.
Every iPhone, iPad or Android device is a station, all live on one list.
QR verification keeps running without a connection and syncs as soon as it's back.
QR code check-in: one scan, one guest, one status.
The QR code on the ticket, PDF or wallet pass is the guest's booking code. The app reads it, shows name, guest group, plus-ones and notes, and marks the guest as checked in. Each code is valid once; a second scan is flagged.
- From screen or paperPDF ticket, wallet pass or printout: the scanner reads all three.
- Plus-ones includedRegistered plus-ones are checked in with the main guest, or separately if they arrive later.
- Guest notesVIP hosting, wheelchair access, a do-not-admit flag or a seat: the app shows what the team needs to know.
- Name searchNo ticket at hand: search the guest, tap, checked in, with a log entry.
Twenty entrances. One guest list.
Each device signs in as a station: North Entrance, VIP, Press, Workshop A. All of them scan the same list, and every scan shows up everywhere instantly. In the cockpit, the event lead sees how full it is, by station and by guest group.
| Station | Device | Checked in | Status |
|---|---|---|---|
| North Entrance | iPad · North-1 | 236 | Online |
| South Entrance | iPhone · South-1 | 142 | Online |
| VIP Lounge | iPhone · VIP-1 | 58 of 64 | Online |
| Workshop A | Android · WS-A | 34 of 40 | Offline · 12 scans pending |
The station name is logged with every check-in; limit guest groups per station, for example VIP only at the lounge.
A second scan at a zone entrance checks group or ticket type; turnstiles and scanners for large events come with event access control.
Catering, speakers and the event lead see the same attendance in the cockpit without standing at the door.
Printed on arrival. Not pre-sorted.
The scan triggers the print: name, company, guest group and barcode on the badge, in seconds, at the station's printer. No pickup table with alphabetized badges, no waste from no-shows and no line at the M table.
- Template per guest groupVIP, press and attendees each with their own layout, from the same list.
- Barcode for laterSession check-in, coat check, lead scanning at a booth: the code on the badge is the guest code.
- Walk-ins includedRegistered on site, printed right away, on the list like everyone else.
- More on printingTemplates, formats and printers under event badge printing.
Checking in guests also means handling the cases nobody planned for.
The guest without a ticket, the plus-one who never registered, the colleague standing in for the boss, the reporter with an appointment: the app has a path for each, and every path ends in the same list, with time, station and staff member.
Each code is valid once. A second scan shows when and where the first one happened and does not check in again.
Guests who leave can be checked out, so the head count in the room stays accurate for catering and security.
The door team checks guests in and adds walk-ins but can't edit master data: roles and permissions come from the guest list.
The venue Wi-Fi is not your problem.
QR verification in the check-in app works online and offline. If the connection drops, the station keeps scanning, holds on to the check-ins and syncs them once the network is back. No line forms at the entrance just because a router froze.

The code is checked against the loaded guest list; unknown codes are caught even without a connection.
Once the connection is back, the check-ins appear on the list with the time of the scan.
Dedicated networks, scanners and staff for large events come with event access control.
You know who was there. No counting.
Every scan is a data point: guest, time, station, plus-one. From these come attendance, no-show rate and arrivals over time by guest group, live in the cockpit during the event and afterward in event reporting. The export goes to catering, security or finance.
- Shows and no-showsBy guest group, by station, by hour; who didn't come is one filter away for the follow-up.
- Proof of attendanceTime and station per guest, for compliance, hospitality records and certificates of attendance.

At the door, the team sees what the door needs.
The check-in app shows name, group, plus-one and notes, not consent records, invoices or home addresses. Roles and permissions decide what a station can see and change; every check-in is recorded in the guest's change log.

Sample roles. You assign permissions per user; stations can be limited to specific guest groups.
Check-in is the moment your guest list becomes real.
Invitation, registration, ticket and seating chart have prepared the guest. The scan confirms them, and reporting and CRM keep working with the result. That's why there is no separate door list, only the guest list.

For attendance by room and session, see training management software; for multi-day badges and session scans, conference management. Turnstiles, scanners, printers and staff for large events come with event access control: Munich Airport used it to check in 80,000 attendees through 20 check-in points. Session scans that create leads for exhibitors belong to lead retrieval.
What is an event check-in app?
An event check-in app is a phone or tablet app that registers guests as they arrive at an event: it reads the QR code on the ticket, finds the guest on the guest list, marks them as present and shows the door team what it needs to know, such as guest group, plus-ones or seat. It replaces the paper list and the badge pickup table, because every station reads and writes the same list in real time.
At AirLST, the check-in app for iOS and Android is part of the platform: it works on the guest list that invitations, registration and ticketing have filled. Besides scanning, it checks guests in by name search, registers walk-ins, prints name badges on arrival, collects signatures and reports attendance live. QR verification works online and offline. It is not airline or hotel check-in; it is the organizer's tool at the entrance of their own event.
The app reads and writes the guest list. There is no separate door list.
How does QR code check-in work with AirLST?
- Prepare. The guest list is complete and every guest has a booking code, printed as a QR code on the ticket, PDF or wallet pass. Badge templates and stations are set up.
- Set up stations. Install the app on an iPhone, iPad or Android device, sign in with your AirLST account, choose the event and station name, and connect a printer if you print badges.
- Scan. The scan shows guest, group, plus-one and notes; one tap checks them in, with time and station. Plus-ones are checked in together or separately, and the badge prints.
- Handle edge cases. Name search for guests without a ticket, walk-in registration, adding a plus-one, collecting a signature; a second scan of the same code is flagged.
- Watch it live. Cockpit and app show expected, checked in, open and walk-ins by station and guest group; if the network drops, the station keeps scanning and syncs later.
- Report. Attendance, no-shows and arrivals over time in event reporting, an export for catering and finance, and attendance on the contact in the event CRM.
How is a check-in app different from a paper list or a ticket scanner?
A paper list knows only one state: the moment it was printed. Morning cancellations, late additions and last-minute plus-ones are missing; two entrances have two lists; at the end someone counts check marks. A ticket scanner without a guest list only checks whether a code is valid. It doesn't know who the guest is, whether they bring a plus-one or which area they may enter.
The check-in app does both: it validates the code and knows the guest, because it is the guest list.
That's why every station sees the same state, why it can add walk-ins and print badges, and why attendance is ready after the event without extra work. It's also why check-in is hard to fake: each code is valid once, a second scan is flagged, and a code that isn't on the list is rejected. For large events with turnstiles, access control and staff, event access control adds on-site hardware and service to the app.
What does check-in connect to?
To everything that prepared the guest and everything that works with their attendance: the guest list as the record, event ticketing for the QR code on PDF and wallet passes, event registration for plus-ones and custom fields, the seating chart, badge printing, event reporting and the event CRM.
- Training management: attendance by room and session, certificates of attendance
- Conferences: badge on day one, scans per day and session
- Premieres: scan or name search on the red carpet, the guest group decides the area
Munich Airport ran its summer party, Music Days and Airport Days with 80,000 attendees, QR code tickets and 20 check-in points on AirLST. More projects on the customers page.
