Build a ticketing system — sell, manage, and scan tickets for events at scale.
Event ticketing infrastructure: ticket sales, QR codes, mobile scanning check-in, and real-time capacity management. Custom ticketing systems eliminate per-ticket fees and give you full control over the ticket sale and admission experience.
Event venue, promoter, or event company that sells tickets at volume and is paying significant Ticketmaster or Eventbrite fees — or needs a ticketing system with specific custom features
Ticketmaster takes 20-35% of ticket face value in service fees. Eventbrite takes 3.7% + $1.79 per ticket. At large event scale, these fees are the single largest controllable cost.
Ticketing system technical architecture:
Ticket sales: Event listing page with ticket type selection. Seat selection for assigned seating (SVG seat map with availability state). Shopping cart with hold timer (prevents overselling during checkout). Stripe payment.
Ticket generation: After purchase, unique ticket generated with QR code encoding the order ID + a cryptographic signature. QR code can be validated offline — no network required for scanning.
QR code validation: The QR code contains: ticket ID + event ID + HMAC signature using a server secret key. At check-in, the scanner app verifies the HMAC signature locally (no server call) and then syncs admission status when connected.
Capacity management: Real-time remaining capacity calculation. Sold + held tickets subtracted from total capacity. Alert at 90% capacity.

Questions, answered.
Yes. SVG seat map created from venue layout. Each seat has a section/row/seat identifier. Seat selection during checkout with real-time hold on selected seats. Complexity depends on venue size and seat map intricacy.
High-volume on-sales require a queue system to prevent server overload. Cloudflare Waiting Room handles pre-sale queuing. Included for events expecting 1000+ simultaneous buyers.
