Abstract

A Non-transferable Radio Frequency Identification (RFID) assembly for attachment to an article comprises a RFID module; and a antenna module coupled with the RFID module, the antenna module comprising a conductive layer, a substrate, and an adhesive modification layer between the conductive layer and the substrate, the adhesive modification layer configured such that when the assembly is attached to the article and attempt to remove the assembly will cause the substrate to release and leave the conductive layer intact.

First claim

What is claimed is:

1. A radio frequency identification (RFID) tag, comprising:
a first end that is attachable to an item;
a substrate at a second end of the RFID tag, the substrate coated with a release agent;
an antenna positioned on the release agent between the substrate and the first end;
a layer of adhesive between the antenna and the first end; and
a chip coupled to the substrate via the adhesive, positioned between the antenna and first end,
wherein the RFID tag is configured to be attached to an item at the first end via the adhesive, and wherein the release agent releases the substrate and leaves the remainder of the RFID tag attached to the item in response to an attempt to remove the non-transferable RFID tag from the item.

2. The RFID tag of claim 1 , wherein the attempt to remove the RFID tag does not adversely affect the performance of the RFID tag.

3. The RFID tag of claim 1 , wherein release of the substrate is an indicator of tampering with the RFID tag.

4. The RFID tag of claim 1 , wherein the substrate is completely coated with the release agent.

5. The RFID tag of claim 1 , wherein the adhesive is between the antenna and the chip.

6. The RFID tag of claim 1 , wherein the adhesive is between the chip and the first end.

7. The RFID tag of claim 1 , wherein the chip is coupled with the antenna via one of conductive coupling, inductive coupling, and capacitive coupling.

8. A radio frequency identification (RFID) tag, comprising:
a first module comprising a first substrate and a first antenna;
a second module comprising a chip; and
a layer of adhesive between the first module and the second module,
wherein the RFID tag is configured to be affixed to an article via the adhesive, and wherein the first substrate is releaseable in response to an attempt to remove the RFID tag from the item leaving the remainder of the RFID tag affixed to the item.

9. The RFID tag of claim 8 , wherein the first module further comprises:
the first antenna between the first substrate and the adhesive; and
a release agent between the first antenna and the first substrate, wherein the release agent is configured to release the first substrate in response to the attempt to remove the RFID tag.

10. The RFID tag of claim 9 , wherein the release agent completely coats the first substrate.

11. The RFID tag of claim 10 , wherein the adhesive layer at least completely coincides with the release agent.

12. The RFID tag of claim 9 , wherein the second module further comprises:
a second substrate affixed to the adhesive; and
a second antenna between the second substrate and the chip.

13. The RFID tag of claim 12 , wherein the second module is coupled to the first module via one of conductive coupling, inductive coupling, and capacitive coupling.

14. The RFID tag of claim 8 , wherein the first module is configured to transfer radio frequency energy through the adhesive into the second module.

15. The RFID tag of claim 8 , wherein the attempt to remove the RFID tag does not adversely affect the performance of the RFID tag.

16. The RFID tag of claim 8 , wherein release of the substrate is an indicator of tampering with the RFID tag.
