Zusammenfassung:Managing foreign RFID tags within a secured area involves use of a first RFID portal system to read tag data from an RFID tag present within a first portal zone. A processing device associated with the first RFID portal system is used to determine whether the RFID tag is entering the secured area. The determination is based on an evaluation of a direction of travel of the RFID tag through the first portal zone. Responsive to determining that the RFID tag is in fact entering the secured area, one or more operations are performed to cause a first tag value corresponding to the tag data to be added into a safe to exit (STE) list.
