Portable Multi-Biometric Feature Acquisition Device

Portable multi-biometric feature acquisition devices capture two or more biometric identifiers from a single subject in a single field session, combining fingerprint, iris, face, and palm print collection into one handheld or shoulder-carried unit. Border control officers, law enforcement field teams, and military checkpoint personnel use these devices to enroll and verify individuals against watchlists and biometric databases without requiring the subject to visit a fixed enrollment station.

The fingerprint sensor uses an optical or capacitive flat platen capturing four-finger slap images at 500 or 1000 dots per inch resolution, meeting FBI IAFIS image quality standards for latent print comparison applications. Iris capture uses a near-infrared illuminated camera with autofocus and live eye detection, collecting both left and right iris images in a single acquisition session at distances between 20 and 40 centimeters from the subject’s face. Additionally, facial recognition capture uses a visible light or structured light camera producing a frontal face image meeting ISO/IEC 19794-5 standard geometry and resolution requirements for watchlist comparison at border and checkpoint locations.

Onboard processing runs biometric feature extraction algorithms locally on an embedded ARM or x86 processor, generating standardized ISO or ANSI template files for each captured modality within 2 to 5 seconds of acquisition completion. Furthermore, 1:N watchlist search against locally stored databases of up to 100,000 records completes within 3 to 10 seconds on current device hardware, returning match results with candidate identity and similarity score without requiring network connectivity at the search point. Network-connected search modes transmit queries to central AFIS or iris recognition servers through 4G LTE or WiFi for larger database searches when connectivity is available.

Onboard storage holds between 10,000 and 50,000 complete multi-modal biometric records depending on storage configuration. Moreover, battery runtime supports between 6 and 10 hours of continuous enrollment and verification operations per charge, covering a full operational shift without recharging at forward checkpoint and border crossing locations.

Tactical Supply Pakistan supplies portable multi-biometric feature acquisition devices to border management agencies, law enforcement field operations units, immigration authorities, and military checkpoint formations requiring dependable field biometric enrollment and verification capability across Pakistan’s border and security infrastructure.
