Scan Table QR • Contactless UPI Ordering
Live Cooking Tickets • Waiter Calls • Multi-Role Ops
DineFlow is engineered entirely with Vanilla JavaScript, the native BroadcastChannel API, and zero external runtime dependencies. Here is how dual-screen synchronization operates:
Customer scans table QR code. In-memory cart dispatches orders via localStorage & BroadcastChannel with 5-stage live status tracking.
Kitchen Kanban receives instant broadcast tickets, synthesizes Web Audio concierge chimes, and updates floor matrix without page refreshes.
Because both devices communicate over the browser's hardware-accelerated IPC bus (BroadcastChannel), state transitions occur at sub-millisecond speeds even with no internet connection.
