Buffr Checkpoint, a Visitor Register That Wants to Retire Paper

Field notes

The page frames visitor registration as a privacy-control workflow: arrival is followed by identity assurance, an isolated record, host notification, and sign-out-driven retention. It lists six input channels—NFC, QR, kiosk, USSD, SMS, and assisted entry—and says they converge on one record architecture. Offline local caching and a sync queue are described for connectivity interruptions, while append-only logs and evidence-pack export are presented as audit features.
