1. A system for sorting an item comprising:

  • a plurality of RFLD tags equipped with lights that illuminate in response to a communication;

    a plurality of sorting locations, wherein each of said sorting locations is associated with one of said plurality of RFID tags;

    a data capture device configured to capture sorting indicia from said item;

    a sort assist tool that receives said sorting indicia from said data capture device and determines a sorting instruction identifying a specific sorting location chosen from said plurality of sorting locations;

    an interrogator that receives said sorting instruction and communicates with an RFID tag associated with said specific sorting location such that said light on said RFID tag associated with said specific sorting location illuminates; and

    an item detection device that senses when said item passes the threshold of said specific sorting location and signals said interrogator to stop communicating with said RFID tag associated with said specific sorting location.
