The abstract presents a cutting-edge RFID door lock system that does away with traditional physical keys to improve home security. The system uses state-of-the-art components, such as an RFID (Radio-Frequency Identification) reader and an Arduino microcontroller, to provide a safe, keyless access option for homes. This technology provides homes with more protection and convenience, which is a comfort in a world where theft and unwanted access are ongoing issues. Conventional keys are not the best option for home security because they can be stolen, lost, or duplicated. By using customized RFID cards or key fobs, the RFID door lock system, on the other hand, streamlines the entry procedure while significantly lowering the possibility of unwanted access. An RFID reader module, an Arduino microcontroller, and an electronic locking mechanism are the three most crucial parts of the system. Once the authenticity of the card has been confirmed by the RFID reader, the Arduino microcontroller will utilize the obtained data to initiate the lock. Additionally, the system can be improved with features like smartphone applications for remote access control, which let homeowners monitor and grant access from a distance. This RFID door lock system has many advantages for homeowners, including strong security features, user-friendliness, and the capacity to monitor access events. These features provide homeowners with convenience and peace of mind. RFID-based security systems are an important development in the rapidly developing field of smart home technology.
