Abstract

The invention concerns a security sealing device including a sealing element, an integrated circuit and an antenna connected to the integrated circuit, the integrated circuit and the antenna forming a RFID circuit. The security sealing device is characterized by the fact that said sealing element is conductive and is forming a part of said antenna.

Claims

1. A security sealing device, comprising:

a sealing element;

an integrated circuit; and

an antenna connected to said integrated circuit, said integrated circuit and said antenna forming a Radio Frequency Identification (RFID) circuit, wherein said sealing element is conductive and forms a part of said antenna.

2. A security sealing device according to claim 1, further comprising a housing containing said integrated circuit and a portion of the antenna forming a partial antenna.

3. A security sealing device according to claim 2, wherein said partial antenna comprises a conductive path with two free ends forming respectively a first and a second connecting point, said sealing element further comprising a first and a second end, each of said ends of the sealing element being adapted to be at least one of directly and indirectly connected to one respective connecting point.

4. A security sealing device according to claim 3, further comprising a connector adapted for connecting one connecting point to one end of the sealing element.

5. A security sealing device according to claim 4, wherein said connector is permanently attached to said housing.

6. A security sealing device according to claim 4, wherein said connector is permanently attached to said sealing element.

7. A security sealing device according to claim 4, wherein said connector includes elements acting as at least one of a mechanical tamper-evident system and a locking system.

8. A security sealing device according to claim 4, further comprising a second connector adapted for connecting the other connecting point to the other end of the sealing element.

9. A security sealing device according to claim 3, wherein one connecting point is permanently and directly fixed to said sealing element.

10. A security sealing device according to claim 1, wherein said housing includes visible tamper-evident elements.

11. A security sealing device according to claim 1, wherein said sealing element includes visible tamper-evident elements.

12. A security sealing device according to claim 1, further comprising a second RFID circuit.

13. A security sealing device according to claim 12, wherein said second RFID circuit is adapted to maintain its functionality when the sealing element is broken or separated from the housing.

14. A security sealing device according to claim 1, wherein said sealing element comprises a length between about 1 cm and 5 m.

15. A security sealing device according to claim 1, wherein the antenna and integrated circuit are sealed in a housing comprising at least one of a plastic and a metal and having a diameter from about 5 mm to about 500 mm, and wherein the RFID circuit operates between about 100 kHz up and 950 MHz with at least one of a read only and read/write integrated circuit.
