Systems and methods of tracking objects in a retail store utilizing mobile RFID tag transmitter systems

A retail store radio frequency identification (RFID) customer tracking system, comprising:

• a mobile RFID transmitter system comprising an array of multiple RFID tags, wherein the RFID transmitter system is configured to moveably be positioned at substantially any relevant travel area within a retail store where movement of objects through the travel area is to be tracked;
• multiple RFID tag readers positioned at fixed locations throughout the retail store comprising a first sub-set of at least one of the multiple RFID tag readers positioned to detect RFID signals from the array of multiple RFID tags;
• a tracking control circuit communicatively coupled with the multiple RFID tag readers, implementing code stored in memory and configured to:
• receive, from the first sub-set of RFID tag readers, RFID tag information of each detected first set of RFID tags of the array of RFID tags;
• obtain a first set of rules to identify changes in RFID tag information;
• use the first set of rules to evaluate over time the received RFID tag information and identify over time threshold changes from a set of base information of received RFID signals from the array of RFID tags being read at each of the first sub-set of RFID tag readers, wherein the threshold change is consistent with a first object interfering with the received RFID signals as the first object travels between the array of RFID tags and a corresponding one of the first sub-set of RFID tag readers;
• and
• track the first object without obtaining a unique identifier of the first object as the first object moves relative to the RFID transmitter system and along at least a first travel area of the retail store in which the RFID transmitter system is positioned as a function of the detected changes from the base information of the received RFID signals from the array of RFID tags being read over time.
