Abstract

A transfer resistant RFID tag preferably includes an identification chip, a tag coil, a housing and a cap. The identification chip is electrically connected to the tag coil with two wires. A first quantity of bonding compound is applied to a surface that is slightly greater than a surface area of the identification chip. A second quantity of bonding compound is applied to the surface that is slightly greater than the end surface area of the housing. One end of the housing is attached to the second quantity of bonding compound. Then the identification chip is attached to the first quantity of bonding compound. The cap is snapped over the tag coil and the other end of the housing. If someone tries to transfer the RFID tag from one surface to another, the two wires or the identification chip will be destroyed during removal.

Claims

1. A method of attaching a transfer resistant RFID tag to a surface, comprising the steps of:

connecting electrically an identification chip to a tag coil;

bonding a housing to the surface by applying a first quantity of bonding compound that is slightly greater than the end surface area of said housing, said housing having an inner perimeter;

bonding said identification chip to the surface by applying a second quantity of bonding compound that is slightly greater than a surface area of said identification chip within said inner perimeter; and

securing a cap to a top of said housing.

2. The method of attaching a transfer resistant RFID tag to a surface of claim 1, further comprising the step of:

fabricating the surface from a metal material.

3. The method of attaching a transfer resistant RFID tag to a surface of claim 1, further comprising the step of:

connecting electrically said identification chip to said tag coil with two wires.

4. The method of attaching a transfer resistant RFID tag to a surface of claim 1, further comprising the step of:

providing a housing that is a round tube.

5. The method of attaching a transfer resistant RFID tag to a surface of claim 1, further comprising the step of:

extending inwardly a snap lip from an inside perimeter of said cap, forming a snap slot on an outside perimeter of said housing, said snap slot being sized to receive said snap lip.

6. The method of attaching a transfer resistant RFID tag to a surface of claim 1, further comprising the step of:

retaining said tag coil on a top of said housing.

7. A method of attaching a transfer resistant RFID tag to a surface, comprising the steps of:

connecting electrically an identification chip to a tag coil;

bonding one end of a housing to the, surface by applying a first quantity of bonding compound that is slightly greater than the end surface area of said housing, said housing having an inner perimeter, retaining said tag coil on the other end of said housing;

bonding said identification chip to the surface by applying a second quantity of bonding compound that is slightly greater than a surface area of said identification chip within said inner perimeter; and

securing a cap to a top of said housing, said cap retaining said coil tag relative to said housing.

8. The method of attaching a transfer resistant RFID tag to a surface of claim 7, further comprising the step of:

fabricating the surface from a metal material.

9. The method of attaching a transfer resistant RFID tag to a surface of claim 7, further comprising the step of:

connecting electrically said identification chip to said tag coil with two wires.

10. The method of attaching a transfer resistant RFID tag to a surface of claim 7, further comprising the step of:

providing a housing that is a round tube.

11. The method of attaching a transfer resistant RFID tag to a surface of claim 7, further comprising the step of:

extending inwardly a snap lip from an inside perimeter of said cap, forming a snap slot on an outside perimeter of said housing, said snap slot being sized to receive said snap lip.

12. A method of attaching a transfer resistant RFID tag to a surface, comprising the steps of:

connecting electrically an identification chip to a tag coil;

bonding a housing to the surface, said housing having an inner perimeter, forming a snap slot on an outside perimeter of said housing;

bonding said identification chip to the surface within said inner perimeter; and

securing a cap to a top of said housing, said cap including a snap lip extending inwardly from an inside perimeter thereof, said snap slot being sized to receive said snap lip.

13. The method of attaching a transfer resistant RFID tag to a surface of claim 12, further comprising the step of:

fabricating the surface from a metal material.

14. The method of attaching a transfer resistant RFID tag to a surface of claim 12, further comprising the step of:

connecting electrically said identification chip to said tag coil with two wires.

15. The method of attaching a transfer resistant RFID tag to a surface of claim 12, further comprising the step of:

applying a first quantity of bonding compound to the surface that is slightly greater than a surface area of said identification chip, applying a second quantity of bonding compound to the surface that is slightly greater than the end surface area of said housing.

16. The method of attaching a transfer resistant RFID tag to a surface of claim 12, further comprising the step of:

providing a housing that is a round tube.

17. The method of attaching a transfer resistant RFID tag to a surface of claim 12, further comprising the step of:

retaining said tag coil on a top of said housing.
