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 implementing a 1:1 matching solution in conjunction with a card-based system
∙ High Level of Security Solution

User Guide

Facial Recognition

Stand at a distance of 50–60 cm (19.6-23.6 in) from the product, and look at the face camera.   Adjust your face so it is parallel to the camera.   The face camera will recognize your face and the face mode icon will blink blue.

Palm Vein Recognition

Spread your fingers and place your hand perpendicularly to the palm vein sensor.   Align the center of your palm with the center of the sensor.   Then move your hand slowly and place it 3.5-7 cm (1.3-2.7 in) from the product.   The palm vein sensor will scan your palm and the mode icon will blink blue.   Remain still while your palm vein is being scanned.
