Design of Employee Attendance Monitoring System by Using Radio Frequency Identity Cards

Nowadays, there have been ascent in the number of usages based on Radio Frequency Identification (RFID) systems. The RFID system have been successfully applied to different areas transportation, medical, agriculture, and industrial to name a few. RFID technology facilitates automatic wireless identification using ID tags and reader method. In our project RFID cards are used to denote members are present in class at the time. In RFID cards are having the magnetic coil which gives the Radio frequency to the reader. After reading coil’s frequency it stores the attendance to the computer. A microcontroller (also MCU or µC) is a functional computer system-on-a-chip. It includes a processor core, memory, and programmable input/output peripherals. Microcontrollers restrain an integrated CPU, memory and capable of input and output.   Microcontrollers are used in automatically controlled products and devices, which is automobile engine control systems, remote controls, office machines, appliances, power tools, and toys.
