ABSTRACT:
In an RFID system having an edge controller and a tag reader that is operably connected to the edge controller, a manifest of items having RFID tags tracked by the RFID system is identified, and data from the manifest is downloaded to the edge controller in anticipation of reading the RFID tags, i.e., the manifest data is prefetched. An RFID edge controller that may be operably connected to a tag reader receives, in anticipation of the tag reader reading RFID tags associated with items, manifest data prefetched from a database that stores manifests of items, and compares the manifest data with data read from the RFID tags to determine whether the items comply with the manifest.
