Technical Advantages About Fingerprint Scanners

The Fingerprint Scanner technology uses near-infrared light to observe the increase in blood flow. The researchers also found that this technology can be used to capture images of digital veins. Since the images of each finger are different, the digital vein image based on the principle of Recognition technology is very likely to become a reality.

Digital vein recognition is a new type of biometric recognition technology that uses fingerprint scanning distribution images to identify. Its working principle is based on the fact that the blood flowing in the human finger can absorb light of a specific wavelength, and the finger can be obtained by irradiating the finger with light of a specific wavelength. Scanned clear images.
Using this inherent scientific feature, the obtained image is analyzed and processed to obtain the biometrics of the fingerprint scan and then the obtained fingerprint scan feature information will be compared with the pre-registered fingerprint scan feature in order to confirm the identity of the registrant.
Compared with other biometric technologies, digital vein authentication has the following main advantages:
1. Biometric technology, rank, no theft, no memory password burden.
2. The internal information of the human body is not affected by the rough skin and the external environment.
3. Suitable for a wide range of people, high precision, reproducible, unforgeable, safe and convenient.
Vein recognition is to use the fingerprint scanner to obtain personal fingerprint scanning distribution map, store the characteristic value, draw the vein map in real time during comparison, and extract the characteristic value for matching to identify personal identity. This technology overcomes the slow speed of traditional fingerprint recognition and the Defects such as stains or finger skin peeling off improve the recognition efficiency.
The light transmission technology can ensure the high contrast of the fingerprint scanning image without being affected by defects and defects such as skin surface wrinkles, texture, roughness, dry humidity, etc. Since the comparison of fingerprint scanning lines only requires a small amount of biometric data, the developed The world's fastest and most accurate personal identification system has been implemented effectively in small, user-friendly and affordable personal identification devices.
