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. If you have a phone with a fingerprint scanner, or facial recognition to unlock it, you’re using biometrics. There are fitness centers switching to biometrics for member access and even professional businesses using them for employees to gain access, clock in and out, and make purchases (such as lunches in cafeterias) within the company.
How the scanner actually works depends on the feature being measured. Fingerprint scanners work by shining a bright light over your fingerprint and taking what is effectively a digital photograph. The image then feeds into a computer scanner. The scanner uses a light-sensitive microchip to produce a digital image. The computer analyzes the image, selecting just the fingerprint, and then uses sophisticated pattern-matching software to turn it into a code.
Facial recognition works by using an algorithm to identify features of a persons face. The system saves this data, and when they return the scanner will compare your face to the saved data allowing them access to whatever it may be.
We use a facial recognition scanner for our 24/7 members here at the Technology Center. If you would like to see it in action or have any other questions, feel free to stop in!
