Food Delivery Data Formats

Simulate and validate data structures for food delivery operations.

1. Order Data Structure

2. Menu Data Structure

3. Driver Data Model

🧮 Food Delivery Algorithms

Simulate route optimization and driver assignment algorithms.

1. Route Optimization

Algorithm: Dijkstra's shortest path with real-time traffic adjustment

2. Driver Assignment Algorithm

Algorithm: Multi-factor scoring (distance, rating, capacity, current load)

3. ETA Calculation

📡 Real-time Communication Protocol

Simulate WebSocket connections and real-time updates.

1. WebSocket Connection

Protocol: WSS (WebSocket Secure) with JWT authentication

2. Order Status Updates

12:00:00
Order Placed PENDING
12:00:15
Restaurant Confirmed CONFIRMED
12:05:30
Preparing Food PREPARING
12:18:45
Ready for Pickup READY
12:22:10
Picked Up by Driver OUT FOR DELIVERY
12:35:20
Delivered DELIVERED

3. Push Notifications

🔌 Third-party Integration

Simulate integration with POS systems, payment gateways, and mapping services.

1. Restaurant POS Integration

Note: This simulator demonstrates API calls to common POS systems.

2. Payment Gateway Integration

3. Mapping Service Integration

📱 QR Codes & Verifiable Credentials

Generate QR codes for orders and create verifiable credentials for delivery proof.

1. Order QR Code Generator

Use Case: Customers scan QR code to track order in real-time
📱

2. Delivery Verification QR

Use Case: Driver scans customer QR to confirm delivery

3. Verifiable Credential - Delivery Proof

Standard: W3C Verifiable Credentials for cryptographic proof of delivery

4. Contactless Delivery Proof

Privacy: Photo proof is encrypted and only accessible to authorized parties
