Some of the most popular employee time and attendance systems use a plastic badge (a wallet sized card) or other fob as a punch in method. Many of these systems are Proximity driven, meaning they have a radio frequency identification (RFID) transceiver built into the hardware. Additional badge configurations may include Barcode, Magnetic swipe and HID. Most of these time clock terminals have numeric keypads to allow for option personal identification number (PIN) code entry method as well. Time tracking security can be enhanced by issuing badges (and refraining from issuing PIN codes) and implementing a policy whereby employees are required to carry their badges at all times. While time clock fraud can be costly; in many instances “buddy punching” is a crime of convenience. By spot checking or overseeing the clock, administrators can create an atmosphere that cuts down on such theft.
