Fingerprint Biometric Machine
Biometrics are automated methods of recognizing a person based on a physiological or behavioral characteristic. Among the features measured are face, fingerprints, hand geometry, handwriting, iris, retinal, vein, and voice. Biometric data are separate and distinct from personal information.
A facial recognition system uses biometrics to map facial features from a photograph or video. It compares the information with a database of known faces to find a match. Facial recognition can help verify personal identity, but it also raises privacy issues.
A biometric identifier known as a retinal scan is used to map the unique patterns of a person's retina. The blood vessels within the retina absorb light more readily than the surrounding tissue and are easily identified with appropriate lighting.
With biometric access cards, the cardholder's fingerprints are registered directly on the card. This way, each card is linked to a specific person. The user authenticates at the door by holding the finger on the fingerprint sensor on the card before the card is held in front of the card reader.
Biometric Access Control is a system that holds the door for intruders and prevents them from accessing the resources by verifying them as unauthorized persons on the basis of biometrics authentication. If the compared information matches, the Biometric Access Control system allows the person to access the resources.
