RFID-Based Security and Access Tracking System

Development of an RFID-based digital access control and monitoring system for institutional security.

This project focused on developing an RFID-enabled security and access tracking system to improve laboratory and building safety within the university environment.
It was funded by the Shahjalal University Research Center (SUSTRC) during 2016–2017.

🔐 Overview

The system was designed to authenticate user entry through RFID tags and automatically log access data to an online database.
This provided real-time visibility into personnel movement, enhancing accountability and facility security.

My key contributions included:

  • Circuit and PCB design for RFID tag reader integration
  • Firmware development for microcontroller-based access verification
  • Database and network interface setup for remote data logging
  • Testing and calibration for reliability under varied use conditions

⚙️ Technical Features

  • RFID-based ID authentication using unique tag serials
  • Microcontroller-driven control (Atmega328p) with serial-to-Ethernet communication
  • Online MySQL database for access time and user tracking
  • Modular architecture allowing expansion to multiple access points
