Biometric identification has a growing role in our everyday security.
Physical characteristics are relatively fixed and individualized — even in the case of twins.
Biometrics scanners are hardware used to capture the biometric for verification of identity.
These scans match against the saved database to approve or deny access to the system.
Each person’s unique biometric identity can be used to replace or at
least augment password systems for computers, phones, and restricted access rooms and buildings.
