Biometric Technologies


CrucialTrak’s unique facial recognition technology presents the fastest,  most advanced and convenient experience for every users.   Facial Images are captured in most accurate 3D patterns from widest angles of access paths.

– Automated face tracking module captures face with wide range of heights (heights range from 120cm to 220cm/3’11” to 7’2”) 
– Precisely captures only targeted image (Automatically eliminates other background face images)
– Real-time facial identification under 0.001 second
– Low light level counter-light support

Palm Vein

CrucialTrak’s   Full Touchless palm vein recognition,  simultaneously interlocked with fingerprint recognition,  provides the fastest learning,  most accurate,  and highly comfortable identification experience,  with the design built by Bio-Mechanism UX analysis.

– Advanced matching algorithms ensure high level of accuracy
– Contactless user interface eliminates hygiene concerns
– Less than 0.00001% false acceptance rate


∙ Ideal for the transition from conventional card systems to biometrics
∙ High Level of Security with Small & Medium Size Offices
