Patent number: 11727224Abstract: This disclosure is directed to techniques for determining respective locations of radio-frequency identification (RFID) tags distributed within a materials handling facility using planogram data that indicates respective item locations of items in the facility. In some examples, the techniques utilize item-identifying carts that automatically identify items that the users place in their carts as they move around a facility. Upon identifying an item, the identity of the item may be provided from the cart to one or more servers, along with an indication of an RFID tag detected by an RFID reader mounted to the cart. Upon receiving the identity of the item and the indication of the RFID tag, the servers may access the planogram data for the facility to determine an item location of the item within the facility and may associate this item location as the location of the RFID tag.Type: GrantFiled: March 18, 2020Date of Patent: August 15, 2023Assignee: Amazon Technologies, Inc.Inventor: Danijel Maricic
