Biometrics consists of identifying individuals based upon one or many unique physical traits (i.e. fingerprint, face recognition, iris, DNA, and so on) or behavioral traits (voice, typing rhythm, so on). This technology is essentially used to capture information about an individual in order to give them access past a specific point. When the person is identified, their physiological or behavioral traits are scanned, and linked to one’s personal information. If there is a match, the person should be allowed access past this point, if properly used. Registering for such device is quite simple. For example, in order to register, one's iris or fingerprint, or both, are scanned and then linked to a name, age, phone number and any other information necessary (Wise Geek).
Biometric devices are continuously improving their convenience and precision. From a security standpoint, some devices still need improving such as DNA testing however; their overall systems are effective. According to various sources, biometrics will become the standard for safety measures within and outside organizations in the future (eHow).
