A biometric attendance machine is a device which is used to verify the identity of a person. The characteristics used to identify a person include fingerprints, voice patterns, iris, face recognition, and hand measurements. These biometrics are unique for every individual and the data in the biometric devices cannot be shared or hacked. It replaces the traditional security method of entering passwords or codes.
Biometric technology scans the fingerprint of the employee and maps the endpoints and intersection of the same. These are then referred with the stored data of the employee. An employee cannot use the biometric system to log in or log out until his/her data is entered into the system.
