Zusammenfassung:A system and method for error correction using radiofrequency identification (RFID) signals. The method includes analyzing one or more signal properties of received RFID tag data obtained from location tag(s) associated with one or more predetermined locations and item tag(s) associated with one or more items in the scan zone. The current location of the items is calculated based on the analyzed signal properties, such as, but not limited to, signal strength. If an item is located in the correct location, the assigned location of the item is verified. If the current location of the item differs from an expected location, the item location data for that item is updated with the current location of the item in a data store. Error correction data is generated, which can include updating the item location and/or providing instructions to move the item from the item' s current location to the assigned item location.
