Radio Frequency Identification Cards
The latest employee attendance tracking technology in vogue is the Radio Frequency Identification (RFID) Cards or smart cards. These tiny computer chips use electromagnetic energy in the form of radio waves to identify, track, and store information. Embedding the RFID chip in the employee's identity card, clothing, or under the skin is a foolproof way of tracking his movement, time, and attendance in a foolproof way.
While ordinary computer-based attendance trackers automate the process, they still require an action from the employee to trigger the record. The RFID chip revolutionizes employee time and attendance tracking by automating the entire process. This captures the required data automatically without the employee making any specific effort. RFID also allows tracking the real-time movements of an employee.
The RFID technology helps track time and attendance records in interactive real-time basis. It also provides for a host of other related applications in real time such as identifying tardiness and absenteeism, managing labor resources to reduce or eliminate overtime, and additional factors.
RFID also finds use for a host of other applications such as locating people in times of emergency and measuring employee behavior. Such uses can, however, attract charges of invading workers' privacy.
