Engineers Unify Event Data at Saudi Mega-Exhibitions Using State Machines and RFID

A technical write-up describes how engineers tackle data fragmentation at large Middle East exhibitions with over 10,000 delegates, where separate ticketing, scanning, and booking tools often produce conflicting exports. For LEAP 2026, a custom VIP booking pipeline was built for HUMAIN, using a state machine that moves meetings from pending qualification to manual review to confirmation. Each state change triggers background workers that send calendar invites and automated reminders while streaming logs to a live dashboard. At the 25th WPC Energy Congress in Riyadh, RFID-based kiosk authentication and gameplay data were fed into the same central analytics system. The authors argue that merging these digital and physical data sources gives organizers a single source of truth.
