Abstract

A method, system and apparatus for pairing authorized NFC enabled RFID devices with an intended object or product. The method, system and apparatus can include a primary RFID with a radio frequency identification chip, a coil antenna, a bridge and a substrate; an association of the at least primary RFID device with an object; an integration of a material into one of the at least primary RFID device and the object that provides the RFID device with a predetermined resonant frequency; and the detuning of one or more secondary communication devices located proximate the RFID device.

Claims

1. A method for pairing an NFC enabled RFID device with an object comprising:

providing at least one RFID device with a RFID chip, an antenna, a bridge, and a substrate;

associating the at least one RFID device with the object;

integrating a material into the at least one RFID device and the object the material provides the RFID device with a desired resonant frequency; and

detuning one or more unauthorized communication devices that are not designed for a loaded resonant frequency to compensate for the material located in the at least one RFID device.

2. The method of claim 1, wherein the antenna is a coil antenna.

3. The method of claim 1, wherein the RFID device is placed on a poster.

4. The method of claim 2, wherein the poster has a touch point area.

5. The method of claim 4, wherein the touch point detunes the use of any of the unauthorized communication devices placed in proximity to the RFID device.

6. The method of claim 1, wherein the substrate comprises at least one of a dielectric material, a permeability material, a resonant inductive circuit, and a conductive region.

7. The method of claim 1, wherein the at least one RFID device has an interrogation range of two inches or less.

8. The method of claim 1, wherein the at least one RFID device incorporates a conductive region as a load compensator.

9. The method of claim 1, wherein the material is a high relative permeability ferrite.

10. The method of claim 1, wherein the material is a high constant ceramic or a conductor.

11. The method of claim 1, wherein the material is a combination of a high relative permeability ferrite and a high dielectric constant ceramic.

12. The method of claim 1, wherein the loaded resonant frequency is a resonant frequency of the RFID tag when placed in a configuration found in an application use case.
