The principle of finger vein recognition is to make use of the absorption of specific wavelength near infrared by the swollen blood flow of human fingers. When the finger is irradiated with near infrared, the near infrared ray can be absorbed in the part with blood vessel lines, so as to obtain the characteristic image of finger vein. After the image is analyzed and processed, the characteristic value of vein information can be obtained through algorithm conversion. Identification authentication is achieved by comparing with pre-registered features.
It is not affected by external general environmental factors (such as humidity, etc.) and the surface characteristics of the recognized body (such as rough skin, dry skin, etc.).
The veins are natural living certification, using the internal characteristics of the human body, difficult to steal, difficult to fake.
Collection is simple and fast, does not require finger pressure, and almost everyone can use finger vein authentication.
With high precision recognition ability, false recognition rate < 0.0001%, rejection rate < 0.01%.
