## 🌟 Overview

The WIA-IND-021 standard defines the framework for Smart Store technology, including automated checkout systems, computer vision-based product recognition, smart shelf technology, customer analytics, digital signage, and intelligent inventory management.

**홍익인간 (弘益人間) - Benefit All Humanity** - This standard aims to revolutionize retail experiences through seamless, personalized, and efficient shopping while reducing operational costs and improving customer satisfaction.

## 🎯 Key Features

- **Automated Checkout**: Walk-in, grab, and go (Amazon Go style)
- **Computer Vision**: Real-time product recognition and tracking
- **Smart Shelves**: Weight sensors, RFID, and inventory monitoring
- **Customer Analytics**: Heatmaps, dwell time, and path tracking
- **Digital Signage**: Dynamic pricing and personalized promotions
- **Electronic Shelf Labels**: Real-time price updates and product info
- **Smart Shopping Carts**: Self-scanning and navigation assistance
- **In-Store Navigation**: Indoor positioning and wayfinding
- **Personalized Recommendations**: AI-driven product suggestions
- **IoT Inventory Sensors**: Real-time stock monitoring and alerts

## 📊 Core Concepts

### 1. Automated Checkout System

```
Checkout Flow:
1. Customer enters store (identified via app or biometric)
2. Computer vision tracks customer movement and product interactions
3. Items automatically added to virtual cart when picked up
4. Items removed from cart when put back
5. Customer exits, payment automatically processed
6. Digital receipt sent to customer app
```

### 2. Store Zones

```
Smart Store Layout:
- Entry Zone: Customer identification, authentication
- Shopping Zone: Product shelves with sensors and cameras
- Hot Zones: High-traffic areas with analytics
- Checkout Zone: Traditional or automated checkout
- Exit Zone: Payment verification, anti-theft gates
- Backroom: Inventory management and fulfillment
```

### 3. Technology Stack

| Technology | Purpose | Accuracy |
|------------|---------|----------|
| Computer Vision | Product recognition | 99.5%+ |
| RFID Tags | Item tracking | 99.9%+ |
| Weight Sensors | Shelf inventory | 99%+ |
| IR Sensors | Customer tracking | 98%+ |
| Indoor GPS | Navigation | 1-3m |
| Edge AI | Real-time processing | <100ms |

## 🔧 Components

### TypeScript SDK

```typescript
import {
  SmartStoreSDK,
  createCheckoutSession,
  trackCustomer,
  monitorInventory,
  updateDigitalSignage,
  analyzeHeatmap
} from '@wia/ind-021';

// Initialize smart store
const store = new SmartStoreSDK({
  storeId: 'store-001',
  location: { lat: 37.7749, lon: -122.4194 },
  enableVision: true,
  enableRFID: true,
  enableAnalytics: true
});

// Create automated checkout session
const session = await createCheckoutSession({
  customerId: 'customer-123',
  entryTime: new Date(),
  authMethod: 'mobile-app'
});

// Track customer movement
const tracking = await trackCustomer({
  sessionId: session.id,
  zone: 'dairy',
  position: { x: 10.5, y: 25.3 },
  timestamp: new Date()
});

// Monitor real-time inventory
const inventory = await monitorInventory({
  shelfId: 'shelf-42',
  productId: 'prod-milk-001',
  currentStock: 12,
  threshold: 5
});

console.log('Session:', session);
console.log('Tracking:', tracking);
console.log('Inventory:', inventory);
```

### CLI Tool

```bash
# Create checkout session
wia-ind-021 checkout create --customer-id customer-123 --auth-method app

# Track customer
wia-ind-021 track --session-id sess-456 --zone produce --position "12.5,30.2"

# Monitor inventory
wia-ind-021 inventory monitor --shelf-id shelf-42 --threshold 5

# Analyze heatmap
wia-ind-021 analytics heatmap --zone dairy --period today

# Update digital signage
wia-ind-021 signage update --display-id disp-10 --content promo-dairy.json

# Generate store report
wia-ind-021 report generate --type daily --date 2025-12-26
```
