Biometrics is a new technology that is able to confirm a person’s identity through the analysis of that individuals’ behavioral or physical characteristics. Within access control, these systems can include voice, retina and fingerprint recognition systems. The advantages over other keyless methods is found in the level of security offered.

Biometric systems are able to grant access based on unique traits; such as fingerprints, vocal sounds, and retinas of the eye that cannot be easily lost. These unique traits are also nearly impossible to duplicate by anyone seeking to tamper with the protected system.
