Mobile shopping app proves walk‑in detection by embedding inaudible ultrasound codes at ~21 kHz and combining that with Bluetooth Low Energy beacons to solve the “threshold” problem. Patented ultrasound + BLE hybrid hardware (ShopBeacon) marks presence, triggers personalized offers and awards “kicks” that convert instantly to digital gift cards. Deployment reaches 10,000 stores, 7 million users, $500M driven last year with roughly doubling year‑over‑year growth; privacy is opt‑in, kicks are nontransferable, and retailers pay per incremental purchase.
