Design and Development of an RFID-Based Anti-Theft Bicycle Lock With Alarm, SMS Notification, and Tile Tracking System

Bicycle theft remains a significant concern in urban and academic environments, creating a demand for reliable and intelligent security solutions. This study presents the design and development of an RFID-Based Anti-Theft Bicycle Lock system that integrates electronic authentication, motion and vibration detection, alarm mechanisms, SMS notification, and Tile-based tracking. The system is built around an Arduino Nano microcontroller, utilizing an RFID RC522 module for secure access verification, an MPU-6050 sensor for detecting unauthorized movement, and a solenoid lock for physical locking control. Visual and audible alerts are provided through an RGB LED and an active buzzer, while real-time SMS notifications are delivered to the bicycle owner using a SIM800L GSM module. In the event of unauthorized access or suspicious movement, the Tile tracker allows the bicycle to be located through a smartphone application.
