Four pillars, one workflow. 01 Document Capture: Camera-driven MRZ scan with torch, autofocus, server-side image cleanup and full check-digit validation. 02 Biometric Verification: ArcFace 512-d descriptors compare the holder against the BMIS photo and the on-chip ePassport image. 03 Geofenced Operations: Admins draw border posts on a live map; officers outside the radius are signed out automatically. 04 Unified Intelligence: Movements, watchlist hits and overstayers stream from one source of truth into a single supervisor portal.
