## 📊 Core Concepts

### 1. Ticket Structure

```json
{
  "ticketId": "TKT-2025-EVT001-A12-0001",
  "eventId": "EVT-2025-001",
  "eventName": "World Music Festival 2025",
  "venue": {
    "id": "VEN-001",
    "name": "National Stadium",
    "location": {
      "address": "123 Stadium Ave, City, Country",
      "coordinates": { "lat": 37.7749, "lon": -122.4194 }
    }
  },
  "seat": {
    "section": "A",
    "row": "12",
    "seat": "15",
    "type": "VIP",
    "accessible": false
  },
  "holder": {
    "name": "John Doe",
    "email": "john@example.com",
    "phone": "+1-555-0123",
    "verified": true
  },
  "pricing": {
    "originalPrice": 150.00,
    "finalPrice": 135.00,
    "currency": "USD",
    "taxes": 15.00,
    "fees": 10.00,
    "discounts": [
      { "type": "early-bird", "amount": 25.00 }
    ]
  },
  "validity": {
    "issueDate": "2025-01-15T10:00:00Z",
    "eventDate": "2025-06-20T19:00:00Z",
    "expiryDate": "2025-06-21T02:00:00Z",
    "timezone": "America/New_York"
  },
  "security": {
    "qrCode": "QR-SHA256-BASE64ENCODED...",
    "barcode": "128-CODE-1234567890",
    "blockchain": {
      "hash": "0x742d35Cc6634C0532925a3b844Bc9e7595f0bEb",
      "network": "ethereum",
      "verified": true
    },
    "signature": "DIGITAL-SIGNATURE-HERE"
  },
  "status": "active",
  "transferable": true,
  "resellable": true,
  "checkInStatus": "not-checked-in",
  "metadata": {
    "issuer": "TicketMaster Pro",
    "platform": "WIA-IND-019",
    "version": "1.0.0"
  }
}
```

### 2. Dynamic Pricing Algorithm

The standard implements a sophisticated pricing engine:

```
P(t) = B × D(t) × T(t) × M(t) × S(t)

Where:
- P(t) = Price at time t
- B = Base price
- D(t) = Demand factor (0.5 - 3.0)
- T(t) = Time decay factor (early bird to last minute)
- M(t) = Market condition multiplier
- S(t) = Supply scarcity factor
```

### 3. Security Features

- **QR Code**: AES-256 encrypted, time-based one-time codes (TOTP)
- **Blockchain Verification**: Immutable ownership records on Ethereum/Polygon
- **Biometric Binding**: Optional fingerprint/face ID linkage
- **Geofencing**: Location-based validation at venue entry
- **NFC Integration**: Contactless validation using NFC technology
