Abstract:
1. A method for automatically inferring correlations between entities having RFID tags, comprising steps for: repeatedly scanning a location having one or more zones of interest using one or more RFID tag readers; storing all RFID tag data captured by any of the RFID tag readers to a computer readable storage medium; repeatedly evaluating the stored RFID tag data, including co-location of RFID tags within particular zones, to infer correspondences between two or more RFID tags; repeatedly evaluating the stored RFID tag data, including RFID tag movement and RFID tag co-movement between two or more zones, to infer relationships between RFID tags; and repeatedly evaluating the RFID tag correspondences and relationships to infer a type of RFID tag, including which of the RFID tags represent people (“person tags”), and which of the RFID tags represent objects (“object tags).
