QR-Based Attendance System
Overview
A QR-Based Attendance System is a digital solution designed to streamline the process of marking and managing student attendance in schools, colleges, and universities. The system replaces traditional manual attendance methods with a QR code-based approach, making it more efficient, accurate, and less time-consuming.
In this system, each student is assigned a unique QR code, which they scan upon entering the classroom. The system automatically records their attendance, stores their details in a database, and can generate reports for teachers and administrators.
Features
1. Student Registration & QR Code Generation
Each student is registered in the system with details such as name, roll number, course, and email ID.
A unique QR code is generated for each student and can be printed or stored on a mobile device.
2. Attendance Marking
A QR code scanner (mobile or web-based) is used by the teacher to scan student QR codes.
The system records attendance in real-time, storing the student’s ID, date, and time of attendance.
Optional: Geolocation tracking can be implemented to ensure students scan within a designated classroom or campus area.
3. Attendance Database & Reports
Attendance data is stored securely in a database ( MongoDB).
Teachers can view, edit, and generate attendance reports for individual students or entire classes.
The system can send automated email alerts to students who are absent frequently.
4. Dashboard for Teachers & Administrators
Teachers can access a web-based dashboard to view real-time attendance.
Admins can manage student details, attendance records, and analytics to monitor trends.
Data visualization tools (charts/graphs) can show student attendance statistics.
5. Security & Authentication
Role-based authentication (Admin, Teacher, Student).
QR codes can be encrypted to prevent duplication or misuse.
Students must scan QR codes within a time limit to prevent proxy attendance.
Technology Stack
Frontend (Web )
React.js – for building the web-based dashboard.
Backend
Node.js with Express.js – for handling API requests.
Database
MongoDB – for scalable storage.
QR Code Generation & Scanning
qrcode.react (React QR code generator)
zxing / jsQR (QR scanner libraries)
Authentication & Security
JWT (JSON Web Token) – for secure authentication.
OAuth – for login management.
Workflow of the System
Student Registration: Students register and get their unique QR codes.
Attendance Marking: Students scan their QR codes when they enter class.
Data Storage: The system logs attendance records in a database.
Reports & Analytics: Teachers can access and analyze attendance data.
Notifications: Alerts are sent to absent students and parents.
Possible Enhancements
QR Code – To add an extra layer of security.
AI-Based Analysis – Predict student performance based on attendance trends.
Blockchain Integration – To ensure tamper-proof attendance records.
