BiometricsThe term “biometrics” comes from the Greek words “bios” meaning life and “metron” meaning measurement. Biometrics is the science of confirming a person’s identity through the analysis of that individual’s unique physical or behavioral traits.

In access control, biometric systems can include fingerprint-readers and voice and retina-recognition systems. These solutions offer advantages over other keyless methods like card readers, which can be lost or stolen.

In contrast, biometric systems grant access based on unique traits that cannot be easily lost, such as fingerprints, vocal sounds and retinas. These traits also are not easily duplicated by anyone seeking to tamper with the security system.
