Event Ticketing Platform

Inspiration

The inspiration for this project came from the need for a simple, secure, and automated ticketing solution. With physical tickets becoming obsolete, I wanted to build a platform that makes event management and entry seamless. The goal was to provide event organizers with an easy way to manage attendees and prevent ticket fraud using QR code-based verification.

What it does

The Event Ticketing Platform allows users to:

• Create and manage events

• Generate unique QR code tickets upon enrollment

  • Verify tickets at the event entry in real-time

• Protect user data with secure JWT-based authentication

  • Prevent duplicate entries using one-time-use QR tickets

How we built it

The project was built using the MERN stack:

Frontend: React.js, Tailwind CSS for responsive UI

Backend: Node.js, Express.js for API routing and business logic

Database: MongoDB with Mongoose for data persistence

Authentication: JWT for secure, stateless login and token management

QR Code Generation: react-qr-code for generating scannable tickets

QR Code Scanning: react-qr-scanner for ticket validation

Challenges we ran into

Managing JWT token expiration and secure route protection

Preventing duplicate ticket generation for the same event-user pair

Handling real-time ticket validation without overloading the server

Balancing security and user experience in the QR code verification flow

Ensuring cross-device compatibility for the frontend UI
