Method for preventing unauthorized diversion of NFC tags
View Patent ↗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.
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.
