RFID Attendance System SDG4

Abstract

1. Introduction

The RFID-Based Automated Student Attendance System is a fully integrated solution that combines embedded hardware (Arduino + RFID) with a full‑stack software suite to modernise attendance tracking in educational institutions.

Together, they eliminate manual record‑keeping, prevent proxy attendance, and provide educators with an intuitive interface to manage weekly sessions and review attendance analytics.

2. Objective

A smart attendance system that uses RFID technology and Arduino to automatically record student attendance. Each student scans an RFID card, and the system updates an Excel database using binary values (1 = Present, 0 = Absent). The system reduces manual work improves accuracy, and provides instant attendance tracking with LED status indicators.

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

3. Key Features / Modules

• RFID Authentication – Unique UID verification for each student.
• Weekly Attendance Tracking – Supports up to 15 academic weeks (configurable).
• Real‑Time Dashboard – Shows total enrolled, arrivals, departures, and live scans.
• Dual‑Scan Logic – Records arrival (1st scan) and departure (2nd scan) per week.
• Duplicate Prevention – Prevents multiple scans in the same week.
• Multi‑Modal Feedback – LCD, LEDs, and buzzer on the Arduino; browser notifications via the dashboard.
• Excel Database – All attendance data is stored in Attendance.xlsx using openpyxl and pandas.
• Session Awareness – Auto‑detects the current lecture session based on system time.
• Search & Filter – Quickly locate students by name, ID, or RFID UID.
• Persistent Settings – Selected week, session, and COM port survive page refreshes.

• 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?
