How biometric technology works? Any of the biometric identifiers of a person is measure. The sensing device checks all possible dimensions like length, width, thickness, and surface area of the identifier. Resultant unique characteristics are processed and stored on computers as a sample. A mathematical representation of the identifier is retrieved when the user’s identification is required and verified by comparison with the pre held records. In addition, the sensor updates the configurations every time identifiers of the same person are read. The results are automatically processed to cater for different changes over time. Database of biometric identifiers may be stored at a central location, or at place where it is to be used, or on electronic devices.

Biometric in desktop computing has been around for some fifteen years now but it still is a relatively newer concept for the general users to grasp.
