In this paper, we present a dual lock system using radio-frequency identification (RFID) and fingerprint recognition. It is a secure and reliable locking system which can be implemented in home, offices, school and in any kind of organization. Even if the users lost the RFID card, they can unlatch the lock with their fingerprints. Only the registered users are able to access using their fingerprints and the RFID tags. If any unauthorized persons try to have an access, first of all short message service (SMS) will send a text message to an owner using global system for mobile communications (GSM), and at the same time a TTL camera will take a snap of that person and store it in a SD card for reference of the owner. The core of the system is the Arduino Mega 2560 which is interfaced with a fingerprint scanner module, a RFID card reader module, the TTL camera, an SD card module, a GSM shield, a liquid crystal display (LCD) and an electric door strike.
