RFID Based Time Attendance System

RFID is becoming one of the cost-effective technologies for today’s time attendance system. In this paper we proposed a methodology to integrate a RFID reader with Desktop/Notebook trough software application and applied it for the time attendance solution. The communication between Desktop and RFID reader is by serial port connection. We analysed the serial port communication protocol for RFID reader and interfaced with Desktop. This system provides all types of information regarding students and employees, which are used for attendance tracking, curriculum details, and hence can be used for future reference.
