Palm veins are generally located 3 mm below the skin. Palm vein recognition is a technology that uses professional palm vein image acquisition equipment to obtain images of vein vein patterns through the absorption or reflection of special light by oxygen-containing hemoglobin in the blood. The features are extracted by algorithms and the feature templates are stored. , And finally achieve identity verification and identification.

SFT palm vein recognition advantages
SFT palm vein recognition adopts three cutting-edge technologies to realize real living body recognition, non-contact recognition, and high-precision recognition.
It solves the counterfeit and forgery of other biometrics, the safety of characteristic data, and the inconvenience of use.

1)True living body recognition

2)Non-contact recognition

3)High-precision recognition

SFT palm vein recognition core technology

Deep 3D modeling technology

SFT Depth 3D modeling technology is a technology that performs 3D modeling of palm vein images according to different distances and depths, and extracts the 3D feature points after modeling. The deep three-dimensional modeling technology is used to solve the impact of changes in the size, shape, position, angle, and brightness of the palm on the recognition effect, and to ensure ultra-high recognition accuracy in non-contact scenes.
Extremely fast fusion comparison engine

High-Speed Fusion Matching Engine
SFT speed fusion comparison engine is a palm vein feature comparison technology that integrates Edge Quantization detection algorithm and 3D Structure Modeling algorithm, which guarantees ultra-high matching speed and certification performance under a large order of magnitude. FAR (Misrecognition rate or false recognition rate) reaches 0.00001%

In Vivo Biometrics Capturing Technology
The precision optics and compound lighting system independently developed by SFT can promote the full penetration of light into the skin and minimize the influence of external light. Accurately obtain high-quality images of subcutaneous veins and rich feature points, and realize the capture and recognition of biological characteristics of living organisms in the body .

Comparison of SFT Palm Vein Recognition and Other Biometric Recognition Technologies

Palm vein VS Fingerprint
Palm veins are features in the body that will not be worn or damaged and cannot be forged

Palm vein VS Face
Palm veins are not affected by facial expressions, accessories, makeup, and have good stability and uniqueness

Palm vein VS Iris
Palm vein products are easy to use, more friendly, and better accepted by users

Palm vein VS Finger vein
The image area of palm veins is large and the information is richer, which can guarantee the recognition accuracy
