Abstract
Embodiments herein describe a package management system that uses two operation modes of RFID readers (i.e., an inventory mode and a search mode) to provide feedback to an associate when a package has been mis-sorted. In one embodiment, the RFID readers are attached to one or more RFID antennas which each are disposed overhead a respective container or storage location in a warehouse. For example, each of the antennas may have a beam pattern or read region that covers the container. Using the RFID antennas, the RFID reader can query the RFID tags in the container to identify the packages stored in the container. In one embodiment, the RFID reader switches to the search mode after a new package is identified. Using the search mode, the RFID reader can quickly identify when the package is stored in the container and provide prompt feedback to the associate.
