NIS-BMIS gives every border officer a hardened mobile workstation that reads passports, verifies the holder's face against the official photo, and surfaces the traveller's full BMIS history in seconds — online or off. Supervisors monitor every checkpoint from a web portal, draw permitted operating zones on a live map, and see movements the moment they are recorded. The whole platform runs on Nigerian infrastructure, with no third-party recognition services in the chain of custody. 4 integrated channels — mobile, portal, API, BMIS database. 512-d ArcFace descriptors, indexed and matched on Nigerian servers. 0 external recognition vendors in the verification path.
