Benefits of technology
This patent is about a marker that can be used to track the movement of articles, such as in a retail store. The marker has a special circuit that can change its resonant frequency, which prevents it from being detected by EAS systems. The marker can be activated by an RFID signal and will change its resonant frequency to a new value when it is deactivated. The marker can also have an energy harvesting element to collect energy from the surrounding environment and use it to power the marker. The technical effects of this patent are improved marker technology that can prevent detection by EAS systems and enable the marker to operate in a variety of environments.
Problems solved by technology
Conventional deactivation processes for EAS security tags or markers are not convenient for self or mobile checkout due to high power and complexity of the deactivation electronics required to deactivate the same.

Embodiment Construction
[0016]It will be readily understood that the components of the embodiments as generally described herein and illustrated in the appended figures could be arranged and designed in a wide variety of different configurations. Thus, the following more detailed description of various embodiments, as represented in the figures, is not intended to limit the scope of the present disclosure, but is merely representative of various embodiments. While the various aspects of the embodiments are presented in drawings, the drawings are not necessarily drawn to scale unless specifically indicated.
[0017]The present solution may be embodied in other specific forms without departing from its spirit or essential characteristics. The described embodiments are to be considered in all respects only as illustrative and not restrictive. The scope of the present solution is, therefore, indicated by the appended claims rather than by this detailed description. All changes which come within the meaning and ra...

Systems and methods for operating a marker. The method comprising: receiving, by a Radio Frequency Identification (“RFID”) element of the marker, an RFID deactivation signal transmitted from an external device; and responsive to the RFID deactivation signal, supplying power from the RFID element to a detuner element so that the detuner element switches from a first state to a second state. The marker's resonant frequency is changed to a first value that falls outside of an Electronic Article Surveillance (“EAS”) systems operating frequency range when the detuner element switches from the first state to the second state.
Description
BACKGROUNDStatement of the Technical Field[0001]The present disclosure relates generally to Radio Frequency Identification (“RFID”) systems. More particularly, the present disclosure relates to implementing systems and methods for RFID enabled deactivation of Acousto-Magnetic (“AM”) ferrite based markers.Description of the Related Art[0002]A typical Electronic Article Surveillance (“EAS”) system in a retail setting may comprise a monitoring system and at least one security tag or marker attached to an article to be protected from unauthorized removal. The monitoring system establishes a surveillance zone in which the presence of security tags and / or markers can be detected. The surveillance zone is usually established at an access point for the controlled area (e.g., adjacent to a retail store entrance and / or exit). If an article enters the surveillance zone with an active security tag and / or marker, then an alarm may be triggered to indicate possible unauthorized removal thereof fr...
