How does the QR ordering work?

Each table has a unique QR code. Customers scan it with their phone camera, which opens the menu directly in their browser — no app download needed.

Can the restaurant customize the menu easily?

Yes. The admin dashboard allows staff to add, update, or remove menu items, change prices, and update availability in real time.

Does it work offline?

The system includes offline fallback with auto-reconnection. Orders are queued and delivered as soon as connectivity is restored.

Restaurant QR Ordering System

QR-based ordering — customers browse the menu and place their order from their own phone, and it appears in the kitchen queue.

Project Overview

Developed a QR-based digital ordering system that lets customers browse menus and place orders directly from their own phones. Each table has a unique QR code; the customer scans, browses, customises and submits straight into the kitchen queue, with no app to install.

Business Challenge

Manual ordering puts a waiter between the customer and the kitchen. During busy periods the queue of questions and hand-written tickets grows, and orders depend on handwriting being read correctly.

Proposed Solution

Developed a QR-based digital ordering system that lets customers browse menus and place orders directly from their own phones. Each table has a unique QR code; the customer scans, browses, customises and submits straight into the kitchen queue, with no app to install.

Technical Challenge

Getting an order to the kitchen reliably. Implemented WebSocket delivery with automatic reconnection and a polling fallback, so an order still reaches the kitchen if the connection drops.
