Service overview

Overview

Our Smart Retail service enables checkout‑free stores using computer vision, shelf sensors, and account‑linked entry. Customers pick items and walk out, while the system itemizes carts and bills wallets automatically.

Key Capabilities

  • Account‑Linked Entry: Mobile app or NFC credentials open gates.
  • Ceiling Vision: Multi‑camera tracking for customer and item interactions.
  • Shelf Sensors: Weight/RFID updates inventory in real time.
  • Store Brain: Sensor fusion, cart itemization, and fraud checks.
  • Checkout‑Free Billing: Automated payment and receipt delivery.
  • Operations & Analytics: Stock alerts, footfall analytics, and layout optimization.

How It Works

  1. Link Account: Authenticate at entrance via app/NFC.
  2. Pick Items: Vision and sensors detect picks and returns.
  3. Itemize: Store brain maintains live cart per shopper.
  4. Exit: Gates open; billing finalizes automatically.
  5. Operate: Dashboards show inventory, analytics, and incidents.
  6. Scale: Add cameras/shelves; tune models for store layouts.
