Abstract
Official abstract text for this publication.
A method for item scanning in a shopping cart includes detecting a change in a weight of one or more items within a shopping cart. The weight is sensed by a weight sensor disposed in the shopping cart. Each of the one or more items includes a radio-frequency identification (RFID) tag. The method includes switching an RFID reader to an active state and scanning RFID tags of the one or more items with the RFID reader in response to detecting the change in weight. The RFID reader is disposed on the shopping cart. The method includes switching the RFID reader to an inactive state subsequent to scanning the RFID tags with the RFID reader. The method includes determining an inventory of the one or more items based on information from the scanned RFID tags. The inventory includes an item quantity and an item identity.
