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


Absolute touchless UX with capturing 30 micro-fingerprint images in every 1 sec,   CrucialTrak’s unique fingerprint recognition system provides the most assured and fastest authentication environment.

– Hygienic environment through touchless UX
– Captures 4 different fingerprints at the same time
– User Friendly Interface
– Organic 3D recognition and fastest 30 shots/sec matching algorithm


World’s first auto-tracking mechanism with minimized user’s  MTAE (Meantime Attempting Effort).

– Auto Iris Tracking minimizes user’s effort
– Large caliber Zoom Autofocus Control — Long distance identification
– Best image selection algorithm
– Satisfies IEC-62471 Safety Standard
– PWM radiation intensity control
– Partial Iris donut recognition

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


BACS™ (Biometric Access Control System) can be applied from critical infrastructures,  where highest level of security is required,  to small size businesses which have lower security requirements but still want to approve on unique authentication abilities.

User Guide

Palm Vein Recognition

Palm Vein Recognition

Spread your hand and place it perpendicularly to the palm vein sensor. Align the center of your palm with the center of the sensor. Then move your hand slowly up or down at a distance of 3.5–7 cm (1.3-2.7 in) from the product. The fingerprint ToF sensor will scan your palm and the fingerprint light will turn green. Remain still while your palm vein is being scanned.

Facial Recognition

Facial Recognition

Stand at a distance about 50–60 cm (19.6-2.3 in) from the product, and look at the face camera. Adjust your face so it can be parallel to the camera. To recognize your face, the pan and tilt modules are moving in the direction of your face to adjust the angle of camera.

Fingerprint Recognition

Fingerprint Recognition

Place your hand perpendicularly to the fingerprint camera. Place the first knuckle of the finger so that it can cover the camera. Then, adjust your hand at a distance of 9-10 cm (3.5-3.9 in) from the product. The fingerprint ToF sensor will scan your palm and the fingerprint light will turn green. Move your finger closer slowly down to a distance of 3.5-5 cm (1.3- 1.9 in) from the camera. It will sound when your fingerprints are scanned.

Iris Recognition

Iris Recognition

Stand at a distance about 50–80 cm (19.6-31.5 in) from the product. Adjust your face so it can be parallel to the iris camera, and look at the camera for 1–3 seconds. The iris light will turn in red. To recognize your irises, the pan and tilt modules are moving to adjust the angle of camera.
