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 system for blocking unauthorized radio frequency communication comprising:
a NFC enabled RFID device;
an object to which the RFID device is associated; and
a substrate provided with the RFID device and the object wherein the substrate includes at least one of a high dielectric material, a high permeability material, a resonant inductive circuit, and a conductive region and an unauthorized RFID tag designed for a benign substrate will have its performance impaired or incapacitated by the substrate.
2. The system of claim 1 , wherein the device has an interrogation range of two inches or less.
3. The system of claim 1 , wherein the device has a resonant loaded frequency near the operational frequency.
4. The system of claim 1 , wherein the object is a poster having a touchpoint or NFC communication area.
5. The system of claim 1 , wherein the high dielectric material is a ceramic material.
6. The system of claim 1 , wherein the substrate facilitates a change in the RFID device through a coupling of two inductors together.
7. The system of claim 1 , wherein the substrate includes a ferrite material.
8. The system of claim 1 , wherein the RFID device comprises an antenna and a conductive region is added as part of the antenna.
9. The system of claim 1 , wherein the RFID device is a special “keyed” or authorized RFID device which functions on the substrate.
10. A NFC enabled RFID device comprising:
a substrate formed with a load compensator;
a RFID chip coupled to the substrate; and
an antenna formed on the substrate and an unauthorized RFID tag designed for a benign substrate will have its performance impaired or incapacitated by the substrate.
11. The device of claim 10 , wherein the substrate comprises ferrite material.
12. The device of claim 10 , wherein the device incorporates a conductive region as the load compensator.
13. The device of claim 10 , wherein the antenna is a coil antenna.
14. The device of claim 10 , wherein the interrogation range for the device is 2 inches.
15. The device of claim 10 , wherein the substrate is a dielectric substrate.
16. The device of claim 10 , wherein the device is placed on a poster.
17. A NFC enabled RFID device comprising:
a substrate;
a RFID chip;
an antenna coil formed on the substrate having a conductive region which causes a decrease in an inductance of the antenna coil; and the NFC enabled RFID device is placed on a poster such that when an unauthorized tag is placed over the NFC enabled RFID device the unauthorized tag is detuned.
18. The device of claim 17 , wherein the substrate is a high dielectric substrate.
