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 the device comprises a housing containing said integrated circuit and a portion of the antenna forming a partial antenna, that said sealing element is conductive and is connected to said partial antenna and forming a part of said antenna and that at least a part of said sealing element extends outside of said housing, wherein said partial antenna is made of a conductive path with two free ends forming respectively a first and a second connecting point, said sealing element furthermore comprising a first and a second end, each of said first and second end being adapted to be directly or indirectly connected to one respective connecting point.

2. The security sealing device according to claim 1 further comprising a connector that connects one connecting point to one end of the sealing element.

3. The security sealing device according to claim 2 wherein said connector is permanently attached to said housing.

4. The security sealing device according to claim 2 wherein said connector is permanently attached to said sealing element.

5. The security sealing device according to claim 2 wherein said connector includes elements acting as mechanical tamper-evident and/or locking system.

6. The security sealing device according to claim 2 further comprising a second connector adapted for connecting the other connecting point to the other end of the sealing element.

7. The security sealing device according to claim 1 wherein said sealing element includes visible tamper-evident elements.

8. The security sealing device according to claim 1 wherein said housing includes visible tamper-evident elements.

9. The security sealing device according to claim 1 wherein one connecting point is permanently and directly fixed to said sealing element.

10. The security sealing device according to claim 1 further comprising another RFID circuit.

11. The security sealing device according to claim 10 wherein said other RFID circuit is adapted to not lose its functionality when the sealing element is broken or separated from the housing.

12. The security sealing device according to claim 1 wherein said sealing element has a length between 1 cm and 5 m.

13. The security sealing device according to claim 1 wherein said electronic module is sealed in a plastic housing, between a diameter of 5 mm to 500 mm, using RFID technology from 100 kHz up to 950 MHz, with a read only or read/write RFID Integrated Circuit (IC).
