Abstract

RFID Attendance System is an open-source Internet of Things (IoT) project. An RFID-based attendance system using Arduino to automate college attendance. This project is an IoT-based solution built with Arduino and RFID technology to automate student attendance in colleges. It reduces manual errors by 30% and eases administrative work. It is built using C++. Key capabilities include: Detects student ID via RFID tag; Logs attendance via Serial Monitor; Can be extended to SD card or IoT server logging. The complete source code is publicly available on GitHub under the MIT License, making it a useful reference for students building an Internet of Things (IoT) mini project or final-year project.

1. Introduction

This project is an IoT-based solution built with Arduino and RFID technology to automate student attendance in colleges. It reduces manual errors by 30% and eases administrative work.

2. Objective

An RFID-based attendance system using Arduino to automate college attendance.

This project demonstrates how C++ can be applied to a real-world Internet of Things (IoT) problem.

3. Key Features / Modules

  • Detects student ID via RFID tag
  • Logs attendance via Serial Monitor
  • Can be extended to SD card or IoT server logging

4. Technology Stack

C++
  • Arduino Uno
  • MFRC522 RFID Reader Module
  • RFID Tags (Keychain or Cards)
  • Jumper Wires
  • Breadboard or PCB

5. System Requirements

General requirements for this technology stack — check the README for exact versions.

  • Arduino IDE / PlatformIO or a C++ compiler (g++)
  • Target board (e.g. Arduino, ESP32) where applicable
  • Git (to clone the repository)

6. Installation & Setup

git clone https://github.com/Rsc2414/rfid-attendance-system.git
cd rfid-attendance-system

Full setup instructions are in the project README.

7. Future Enhancements

Suggested extensions you can add to make this your own project.

  • Add a mobile dashboard using Blynk or Firebase
  • Store readings in a cloud database for history charts
  • Add alerts via SMS / Telegram when thresholds are crossed

8. Viva / Review Questions

Common questions examiners ask for projects in this domain.

  1. Which microcontroller / board and sensors are used and why?
  2. How does the device send data (Wi-Fi, MQTT, HTTP, Bluetooth)?
  3. Where is the sensor data stored and visualised?
  4. How is power consumption managed?
  5. How would you secure the device and its communication?

9. Source Code & License
