Abstract

A tamper-resistant RFID identification apparatus that includes a mechanism for storing an excess portion of the apparatus when engaged. The apparatus includes a substrate including a series of holes along a length thereof and a slot distal from the series of holes, a tamper-resistant locking mechanism for securing the apparatus to an object, an RFID circuit disposed on the substrate and an electrically conductive loop disposed on the substrate and electrically coupled to the RFID circuit, that is arranged to disable the RFID circuit when cut. The slot receives a tail portion of the substrate when the apparatus is secured.

Claims

1. A tamper-resistant RFID identification apparatus, comprising:

a substrate;

an RFID circuit disposed on the substrate;

a mechanism for disabling the RFID circuit when the substrate is severed;

a tamper-resistant locking mechanism for securing the apparatus to an object; and

a slot located in the substrate to receive a tail portion of the substrate.

2. The apparatus of claim 1, wherein the substrate includes a series of holes along a length thereof.

3. The apparatus of claim 2, wherein the locking mechanism includes:

a peg located at one end of the substrate; and

a locking hole located the same end of the substrate, the peg and the locking hole cooperatively and securely attach to one another to securely engage one hole of the substrate.

4. The apparatus of claim 1, wherein the RFID circuit is located in close proximity to the slot.

5. The apparatus of claim 1, wherein the slot is located in an area of the substrate as not to interfere with viewing of indicia on a surface of the substrate.

6. The apparatus of claim 1, wherein the slot forms a frangible zone in the substrate.

7. The apparatus of claim 1, wherein the RFID circuit includes a loop antenna and an RFID transponder chip:

8. The apparatus of claim 7, wherein the slot forms a frangible zone in the substrate such that at least a portion of the loop antenna is severed upon a break in the frangible zone.

9. The apparatus of claim 7, wherein the slot is surrounded by at least a portion of the loop antenna.

10. The apparatus of claim 1, wherein the mechanism for disabling the RFID circuit includes an electrically conductive loop disposed on the substrate and electrically coupled to the RFID circuit.

11. The apparatus of claim 10, wherein the electrically conductive loop runs along substantially the entire length of the substrate.

12. The apparatus of claim 1, wherein the slot is formed after production of the RFID identification apparatus.

13. The apparatus of claim 1, wherein the slot is located in close proximity to the locking mechanism.

14. A method of adapting a tamper-resistant RFID identification apparatus, comprising:

cutting a slot in a proximal end of a substrate of the apparatus to slidably accept a tail portion of a distal end of the substrate.

15. The method of claim 14, wherein the apparatus includes:

a tamper-resistant locking mechanism for securing the apparatus to an object;

an RFID circuit disposed on the substrate; and

a mechanism for disabling the RFID circuit when the substrate is severed.

16. The method of claim 15, wherein the substrate includes a series of holes along a length thereof.

17. The method of claim 16, wherein the locking mechanism includes:

a peg located at one end of the substrate; and

a locking hole located the same end of the substrate, the peg and the locking hole cooperatively and securely attach to one another to securely engage one hole of the substrate.

18. The method of claim 15, wherein the mechanism for disabling the RFID circuit includes an electrically conductive loop disposed on the substrate and coupled to the RFID circuit.

19. The method of claim 18, wherein the electrically conductive loop runs along substantially the entire length of the substrate.

20. A tamper-resistant RFID identification apparatus, comprising:

a substrate;

an RFID circuit disposed on the substrate;

a mechanism for disabling the RFID circuit when the substrate is severed; and

a slot located in the substrate to receive a tail portion of the substrate.
