Detailed explanation-1: -A biometric device is a security identification and authentication device. Such devices use automated methods of verifying or recognising the identity of a living person based on a physiological or behavioral characteristic. These characteristics include fingerprints, facial images, iris and voice recognition.

Detailed explanation-2: -A biometric device is an electronic device for identifying and verifying individuals. Different types of biometric devices include fingerprint scanners, biometric mobile devices, and facial recognition terminals.

Detailed explanation-3: -In addition to biographic data, many ID systems collect fingerprints, iris scans, facial images, and/or other biometry to use for biometric recognition-automatic recognition of individuals based on their biological or behavioral characteristics (ISO/IEC 2382-37).

Detailed explanation-4: -A biometric sensor is a transducer that converts a biometric treat (fingerprint, voice, face, etc.) of a person into an electrical signal. Generally, the sensor reads or measures pressure, temperature, light, speed, electrical capacity or other kinds of energies.
