Project Title
Attendance: QR code & Location-Based Smart Attendance System
Abstract
Attendance is one of the most important activities in educational institutions and corporate
environments. Traditional attendance methods, such as manual registers or even simple QR
scanners, often suffer from inefficiency and proxy attendance.
To solve these issues, Attendance introduces a modern attendance system that uses QR code
scanning combined with real-time location verification. Faculty generate a session-specific
QR code, students scan it with their mobile device, and the system validates their GPS location
before marking them present.
This ensures accurate, secure, and proxy-free attendance. It also provides real-time reports
for faculty and administrators.
Project Idea
The main idea of QR code Attendance is to create a secure and smart attendance system by
combining:
1. QR Code Scanning – Students scan a unique QR code to record attendance quickly.
2. Location Verification – GPS coordinates confirm that students are physically present
in the classroom.
By merging these two approaches, the system eliminates the chances of fake or proxy
attendance while saving time and effort for both students and faculty.
Applications
1. Educational Institutions – Schools, colleges, and universities to maintain accurate
attendance.
2. Corporate Training Programs – Ensures employee participation is tracked securely.
3. Workshops & Seminars – Allows organizers to log real attendees in real time.
4. Examination Centers – Verifies the presence of students during exams.
Technologies Used
1. Frontend Development
• Next.js (React Framework): For building a modern, responsive web application.
• HTML5, CSS3, JavaScript (ES6+): For structure, styling, and interactivity.
• Tailwind CSS / Bootstrap: For fast and responsive UI design.
2. Backend Development
• Firebase (Backend-as-a-Service):
o Firebase Authentication – For secure login of students and faculty.
o Firestore / Realtime Database – To store and manage attendance records.
o Cloud Functions – To handle backend logic like QR generation and validation.
• Node.js (via Next.js): For API handling and communication between frontend and
backend.
3. QR Code Integration
• qrcode / react-qr-code (NPM libraries): To generate QR codes dynamically for each
session.
• QR Scanner Library: Enables students to scan QR codes using their camera.
4. Location Verification
• HTML5 Geolocation API: To fetch GPS location of students during QR scan.
• Google Maps API (optional): To check location boundaries and apply geofencing.
5. Hosting & Deployment
• Vercel: For hosting the Next.js application.
• Firebase Hosting (optional): Alternative hosting with Firebase integration.
6. Programming Languages
• JavaScript / TypeScript: Primary development languages.
• SQL (optional): If an RDBMS (like MySQL/Oracle) is used in place of Firebase.
