The Event Check-In App That Runs on a QR Scan
Issue a digital pass to every guest, validate it at the door in seconds, and watch arrivals update live — no app to install for you or your attendees.
Whether you're running a conference, a workshop, or a private gala, the door is where the experience starts — and where it most often breaks. Long lines, name-list lookups, and duplicate or shared tickets turn a smooth event into a bottleneck.
PassEngine gives every guest a QR pass they keep on their phone or in Apple/Google Wallet, and gives your team a scanner that checks them in instantly.
Why Check-In Lines Form
Manual check-in slows down the moment the crowd arrives. A typical door process forces staff to:
- Search a printed or spreadsheet guest list for each name
- Eyeball paper or PDF tickets that are easy to forward or fake
- Track who actually walked in across several staff and devices
- Reconcile no-shows, plus-ones, and walk-ups by hand afterwards
With a small guest list it's manageable. At a few hundred arrivals at once, it creates queues, mistakes, and a frustrating first impression.
A Digital Pass for Every Guest
Instead of name lists and paper tickets, PassEngine issues each attendee a unique pass with a QR code. Your team scans it at the door to check guests in instantly — and every scan is logged.
How event check-in works with PassEngine:
Generate a pass for each attendee with their name, ticket tier, table, or any custom field. Make them one by one, in bulk, or automatically from your registration form via the API or Zapier.
Each guest gets a unique link with a QR code. They open it on their phone and add it to Apple Wallet or Google Wallet — no app download required.
Staff check guests in with the built-in PassEngine scanner. Single-use passes flip to "used" on first scan, blocking duplicates and shared tickets.
Watch check-ins update in real time on the dashboard. Use multi-use passes for re-entry or multi-day events and see exactly who is inside.

Yes. Create passes in bulk, or connect your registration form or ticketing tool through the PassEngine REST API or Zapier so a pass is generated automatically for every sign-up.
Single-use passes change to "used" the moment they're scanned, so a forwarded screenshot won't get a second person in. Every scan is timestamped and logged.
