How does biometric technology work? Any of the biometric identifiers of a person is measured. 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 to different changes over time. A database of biometric identifiers may be stored at a central location, 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.
