Attendance registering and recording systems that apply Biometrics use distinct ways of keeping a record on the staff people. Physiological traits of a worker like a handprint, fingerprint, palm scan and even a retinal scan is used as an input for these systems.
Whenever a staff member enters the office premises, he/she will have to pass the process of the scan and only then can he/she be allowed to enter the workstation. Moreover, such systems will ensure that only true employees enter and be able to mark their attendance and arrival time for that particular day.
