ABSTRACT:
System and method for tracking inventory of a multiplicity of products. First RFID tags are associated with respective products or groups of products. Second Active RFID tags are associated with respective first containers for the multiplicity products. A third Active RFID tag is associated with a second container for the first containers. First RFID tags broadcast their respective identifications. Second Active RFID tags hash the identities of the first RFID tags within their respective first containers and broad their hashed values. Third Active RFID tag hash the hashed values broadcast by the second Active RFID tags. An expected value is compared to a result of the third Active RFID tag hashing the hashed values broadcast by the second Active RFID tags.
