How does a biometric sensor work?

How does a biometric sensor work?

Fingerprint scanners work by capturing the pattern of ridges and valleys on a finger. The information is then processed by the device’s pattern analysis/matching software, which compares it to the list of registered fingerprints on file.

What is the purpose of biometric fingerprint?

The technology is mainly used for identification and access control or for identifying individuals who are under surveillance. The basic premise of biometric authentication is that every person can be accurately identified by intrinsic physical or behavioral traits.

How do you use fingerprint scanner biometrics?

The scanner uses a light-sensitive microchip (either a CCD, charge-coupled device, or a CMOS image sensor) to produce a digital image. The computer analyzes the image automatically, selecting just the fingerprint, and then uses sophisticated pattern-matching software to turn it into a code.
