The short answer
Give each guest a QR pass when they RSVP, then scan the pass at the door with any phone. Each scan marks the guest arrived, shows their table, and updates a live count — no printed list, no app for guests.
1. Issue passes: when a guest RSVPs, they get a personal QR pass by text or email. 2. Scan at the door: open the check-in screen and point the camera. 3. Watch the room fill: each scan ticks the count and points the guest to their table. Two greeters can scan at two doors at once.
Frequently asked questions
Do guests need an app to be checked in?
No. Guests just show their QR pass (a link they received); the host scans it in any phone browser. No installs for anyone.
