Jony Digital QR Ticket Engine
High-throughput MERN stack subscription platform for generating and scanning QR tickets
error Extravagant Commission Fees
Event organizers and transit companies were penalized by legacy ticketing portals charging massive percentage-based fees (5% to 15%) on every single ticket sold. Operators required a self-hosted, commission-free platform with flexible subscription options where they could generate unique tickets and scan them securely on-site using any smartphone without native application downloads. Additionally, ticket fraud and duplicates were hard to track with generic PDF passes.
Technologies & Tools
Full-stack API development, MongoDB query optimization, Stripe Webhook integration, secure hashing implementation, and web scanner optimization.
Multi-Tenant Architecture & Verification Flow
To support multiple event operators and transit companies under a single application infrastructure, the platform implements schema isolation, secure key management, and high-concurrency API route logic.
Multi-Tenant Tenant Isolation
MongoDB models partition organizer collections using unique tenant IDs. Indexes are optimized for fast sorting, preventing cross-tenant data leaks and keeping query response times below 40ms.
Cryptographic HMAC Verification
Every ticket JSON payload contains a signature compiled using a system secret. When scanned at the gate, the parser re-hashes the payload locally to confirm authenticity, neutralizing ticket replication.
AJAX Camera Decoders
The browser scanner utilizes HTML5 webcam decoders with custom canvas frame sampling, processing 5 frames per second on entry-level mobile browsers to identify and decode QR matrices instantly.
Development Roadmap
Modeling multi-tenant tables and designing database index parameters.
Setting up Express controllers, Stripe hooks, and cryptographic routines.
Assembling React control boards, QR generation routines, and Chart.js dashboards.
Simulating heavy scan volumes and optimizing gate database caching routes.
Impact & Measurable Outcomes
How commission-free modeling transformed operational margins and event profitability.
Secure QR tickets generated and validated at venues
Flawless subscription billing loops via Stripe integrations
Average round-trip speed to scan and verify tickets
"By switching to Jony Digital's subscription ticketing engine, we completely eliminated ticket commissions and saved over $35,000 in transaction fees during our summer festival series. The browser scanning worked flawlessly at the gates, validating tickets in a blink."
