Event QR-Ticketer
Project Overview
Event QR-Ticketer addresses entry-point bottlenecks and ticket counterfeiting at major conferences and festivals. By utilizing cryptographic signatures embedded directly in dynamic QR codes, this solution ensures offline-verifiable authenticity while keeping validation speeds exceptionally fast. The system is designed to run on low-bandwidth mobile networks at the physical gate while instantly synchronizing check-ins.
The Challenge
High rate of gate authentication fraud and slow attendee validation speeds at large physical conference entrances.
The Solution
Built a Next.js administration portal generating cryptographic QR codes, integrated JWT role authorization, and deployed a real-time MongoDB dashboard for gate staff.
The Outcome
Reduced gate validation time to sub-second speeds and eliminated unauthorized entries completely.
Key Features & Capabilities
- •Dynamic cryptographically signed QR code generator preventing screenshot reuse.
- •Multi-role administration panel (Super Admin, Organizer, Gate Staff) using JWT authorization.
- •Real-time check-in analytics dashboard displaying live attendance graphs.
- •Offline-first validation mode using local database caching on scanning devices.
Technical Architecture
- •Frontend: Next.js (App Router) utilizing Tailwind CSS and lucide icons.
- •Backend: Node.js Express API serving JWT-secured RESTful endpoints.
- •Database: MongoDB for flexible registration metadata and quick scan logs.
- •Cryptography: SHA-256 HMAC tokens embedded in the QR payload.
