RfID Door Lock Using Arduino

Key Points

The aim is to design a security system that enhances access control using RFID technology and Arduino.
Designed an RFID door lock system using Arduino microcontroller.
Utilized an RFID reader to scan unique IDs from cards or tags.
Implemented a comparison between scanned IDs and pre-stored authorized IDs.
The system identifies authorized users effectively based on RFID ID matching.
Reduces issues related to traditional mechanical locks, such as key loss and duplication.

Abstract

This research Security is a major concern in homes, offices, and restricted areas. Traditional lock systems using mechanical keys have limitations such as key loss, duplication, and lack of access control. To overcome these issu es, this project presents the design and implementation of an RFID Door Lock using Arduino. The proposed system uses Radio Frequency Identification (RFID) technology to allow only authorized users to access the door. An RFID reader reads the unique ID of the RFID card or tag and sends it to the Arduino microco ntroller. The Arduino compares the scanned ID with the pre-stored authorized IDs. If the ID matches, the system.
