RFID Attendance

Abstract

1. Introduction

abstract: | Build and demonstrate a system that records attendance by reading RFID tags. The system will consist of:\ a) a WiFi-connected microcontroller and RFID reader,\ b) several RFID tags,\ c) an online database to record tag readings,\ d) a program to use records in the database to compute student attendance.\ This project will require you to integrate embedded microprocessors (Arduino), an RFID reader system, and Internet access. date: Fall 2017 title: 'Internet of Things — RFID Attendance System'

cloud to read the database and compute a daily attendance report.

RFID stands for “Radio-frequency Identification.” Much like a barcode, this technology allows for items or things to be identified. However, the system is entirely electronic and works without the tags requiring a battery to be identified. You will combine several existing items together to create a system that wirelessly takes attendance and records the data on the Internet. You will be using an RFID reader from ThingMagic, a Sparkfun development board, an Arduino microcontroller, and an online database from Mathworks.

2. Objective

Project for GE100. RFID-based system for automatically taking class attendance.

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

4. Technology Stack

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/wiredlab/rfid-attendance.git
cd rfid-attendance

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?
