  • Patent number: 11501346
    Abstract: Customers are identified as they enter a store and linked to one or more items previously ordered on-line. A route through the store to retrieve the ordered items is generated and sent to the customer's mobile device for display. The customer's movements are tracked as he/she goes through the store to retrieve products, and the location of the customer determined whenever he/she selects a product from the shelves. Based on whether the locations of the customer when he/she selected the products matches the predefined locations of the items ordered on-line, the customer is directed to go to one of an audit station or checkout lane, or alternatively, to bypass both audit station and the checkout lane and exit the store. In the latter case, the customer's account is automatically charged for the total cost of the ordered items.
