How does finger vein authentication work?

This technique relies on capturing images of the veins inside one's hand by shining near-infrared light on their fingers. This makes it almost impossible to counterfeit. In addition, blood flow in the veins during identification ensures that the individual is alive and real, rather than a fraudster.

How does vascular pattern recognition work?

How it Works. The subcutaneous blood vessels of the human body form a distinctive pattern for each person. Vein patterns can be captured by illuminating a body region with infrared light, and photographing the reflected light.

Can vein recognition be beaten?

It's true that vein authentication systems are vulnerable to bypasses but so are all other systems yet invented, including fingerprint and facial recognition (Apple's Face ID), and almost any authentication system when used in isolation.

Is vein structure recognition a biometric measure?

Vein pattern is one such biometric which is at the initial stage of investigation and research. The shape of the hand dorsal vein pattern is capable of authenticating a human being.
