What is GateProof?
GateProof is a private event check-in system that issues cryptographically signed QR-code passes and verifies attendees at the door entirely on-device, keeping guest lists off third-party servers. Built for corporate events, private gatherings, weddings, and regulated organizations that require attendee data privacy.

Frequently asked questions about GateProof
Do guests need to install an app?
No. Passes are QR codes sent as PDF, PNG, or through your existing share sheet. Guests just show the QR at the door.
Does it work without internet at the door?
Yes. Scanning and verification are entirely local—no server call needed. Result in under a second, even in dead zones.
How are multiple staff members at different doors kept in sync?
Optional Wi-Fi sync when devices share the same venue network, or Apple Direct when on different networks. Scans still work offline.
How does it prevent duplicate check-ins?
Each pass is cryptographically signed and checked locally. When scanned, it shows VALID (first time), ALREADY USED (repeat), or INVALID (not issued by you).
