ABSTRACT
The objective of this chapter is to develop a RFID card-based attendance system. Each student will be having a RFID tag with a unique ID, which will be first identified and then stored in the program. The stored id will be matched with the RFID tag ID, which will be swiped to the reader to authenticate the presence of a student. The system comprises the Arduino Uno, power supply, RFID reader, and the RFID tag. It operates on a baud rate of 9600. It can be connected to an RS232, which is compatible to the PC or to the UART. RFID tag generates a 12 byte unique ID.
