US 2020/0090481 A1 · FOREIGN RFID TAG DISCRIMINATION AND MANAGEMENT

Abstract

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.

A method for managing foreign RFID tags within a secured area, comprising

using a first RFID portal system to read tag data from an RFID tag present within a first portal zone;
using at least one processing device associated with the first RFID portal system to determine whether the RFID tag is entering the secured area, said determination based on an evaluation of a direction of travel of the RFID tag through the first portal zone;
responsive to a determination that the RFID tag is entering the secured area, performing at least one operation to cause a first tag value corresponding to the tag data to be added into a safe to exit (STE) list maintained in an electronic data storage device accessible to the at least one processing device;
wherein the STE list specifies one or more RFID tags which are permitted to leave the secured area without triggering an alarm.
