SYSTEMS AND METHODS OF TRACKING OBJECTS IN A RETAIL STORE UTILIZING CHANGES IN READS FROM SETS OF PRODUCT RFID TAGS

摘要

In some embodiments, systems and methods are provided to track objects at a retail store, comprising: multiple RFID tag readers to detect a set of different RFID tags each associated with a different item; and a tracking control circuit configured to: receive, from RFID tag readers, RFID tag information of each RFID tag of a subset of the RFID tags; obtain and use a first set of rules to evaluate, over time and for each of the subset of RFID tags, the RFID tag information and identify threshold changes from a set of base information, wherein the threshold change at each of the set of RFID tag readers is consistent with an object moving proximate the RFID tag reader and items corresponding to the RFID tags; and track the object along travel areas as a function of timing of the detected changes from the base information.
