Abstract
A radio frequency (RF) identification (RFID) reader is mounted in a venue in proximity to a portal that is openable and closable by a door. The portal reader reads RFID object tags associated with objects that approach the portal. An electrical conductor is associated, and jointly movable, with the door. A portal RFID tag is mounted at the portal. The portal tag is overlain by the electrical conductor in a closed door position and is remote from the electrical conductor in an open door position. The portal tag is readable by the portal reader in either the open or the closed door position. A controller identifies any objects that have passed through the portal based on whether the object tags have been read, as well as whether the portal tag has been read in either the open or the closed door position.
