Benefits of Biometrics - In some businesses hourly employees have a 5-10 minute window to clock in or out from their shift. If the employee tries to begin or end his shift outside of this time span, a manager must sign off. You can imagine then for someone who is chronically late, or afraid of tarnishing his reputation, how appealing it would be to avoid that confrontation. Enter buddy punching. While time theft isn’t the only problem that biometrics solves, it can be the most costly.
