Food Retailers Carrefour and Nisa Track Shoppers via Bluetooth Beacons in Carts and Baskets

Supermarket giant Carrefour and convenience store group Nisaare piloting a new technology that uses Bluetooth Low Energy (BLE) beacons attached to trolleys and baskets to track a shopper’s journey around the store.

Three Carrefour locations in Madrid are participating in the trial along with three Nisa stores in London.
