ABSTRACT
RFID (Radio Frequency Identification) technology has experienced phenomenal development in recent years. The applications of RFID technology are found in areas such as product tracking, security systems, and inventory control. This study describes design and implementation of an RFID based access control system. To enhance the system security, this system uses a keypad PIN (Personal Identification Number). The control function for this system is provided by an Arduino UNO microcontroller chip.
