The biometric devices are used for security measures.
Broadly, a "biometric device" is any device that measures a biological function or trait. As related to computers, biometric devices are used to control access and/or verify identity. Voice recognition, retinal scanners, palm/fingerprint scanners are all examples of biometric devices. A biometric scanner will take a picture (your fingerprint, your retina) and match it to a previous scan kept on file. Other types of biometric devices, such as voice recognition systems, will record your voice and compare the recording to a sample on file.
Biometric security devices can be purchased from several different companies. Some companies that manufacture biometric security devices are Quick Access, Sentry Safe, Viking, Lock Safe, and Gun Vault.

Biometric devices measure (metric) features of living things (bio). To be useful in security (such as authentication and identification), biometric devices measure features of living things that are unique for any individual, such as the Fingerprint Readers now available on most laptops. Other biometric devices include Voice Print Analyzers, Facial Recognition Scanners, and eye (retina or iris) scanners.

Biometrics is the system of identifying humans through personal characteristics. Examples of biometric systems include the scanning of the iris/retina, fingerprint scanning, and handwriting scanning. Another example of a biometric system is the scanning of the voice in order to recognise the speaker.
