Biometric system measures the unique bilogical characteristics to identify a person. For example, finger print is unique for each individual. So if a system is made to read and register the finger prints, every time when the finger print is read using reader, this will identify the person. This identification can be used for attendance, access control etc.Unlike smart card(which can be stolen or exchanged), biometric system increases the level of authenticity and hence security. Another uniquely identifiable part in human body is pupil of the eye.This is also used in application of high security.The eye scan done in the passport control in foreign countries (eg:DUBAI) is nothing but an application of biometric system.
