Protocol core for Flip rotating multi-frame pass credentials

Turnstile edge bridge — turns any fixed QR scan engine (serial/TCP/USB-wedge) into a Flip lane: decode in, allow/deny decision, relay/HTTP/exec out.

Venue hub — one on-site box that serves manifest/verify/scans to every lane on the venue LAN, owns venue-wide single-use admission during an internet outage, and reconciles to the cloud as one client.

Embed the Flip reader (scanner) — offline credential validation, entry/exit, occupancy, and sync.

Official Flip server SDK — issue, revoke, and recover device-bound rotating pass credentials, manage pass fields, and verify webhooks.

Embed the Flip live, device-bound rotating pass in your web or React-Native app.
