ACKNOWLEDGMENT

We give glory, honor and adoration to almighty God, who is the Alpha and Omega who had made it easier for us through this project.
We also appreciate our supervisor MR. M. O. AYENI for his effort, encouragement, advice and support, when we undertake this project our sincere gratitude also goes to our parents, siblings and those who contribute immensely to the completion of the project.

ABSTRACT

The main purpose of this project is to design and implement a system based on a password using Radio-Frequency Identification RFID. This system is basically a password and an RFID based access-control system which permits only an authorized person to unlock. For doing this, the system will activate and authenticate the user. Application of a security system via a passive ID number form RFID tag was used. Then enter the password from a keypad, if the ID number of the tag and password are correct, then it will unlock. The aim of constructing this system is to put in place a formidable locker security system with low cost and free of errors. Keywords – RFID Reader, Atmega328p, Keypad, LCD, Buzzer. The security system plays a significant role to keep out unknown users to access protected physical and logical places with no permission. Furthermore, unwanted people can hack the lock and have access to the protected place. It can further be use for smart cart can be interfaced with wireless technologies to make it completely portable in the nearest future.
