Abstract:
The present invention addresses deficiencies of the art in respect to commercial asset control and provides a novel and non-obvious system and device for monitoring access to controlled areas. In one embodiment of the invention, the device can include a securing mechanism having an open state and a closed state. The device can further include a housing coupled with the securing mechanism, the housing comprising a radio frequency-opaque material, wherein the housing completely encloses a volume when the securing mechanism is in the closed state and wherein the housing includes an opening when the securing mechanism is in the open state. The device can further include an electronic marker located inside the volume of the housing, wherein the electronic marker periodically emits a signal.
