Abstract

An identification apparatus, such as may be incorporated into a band of material used as a wristband. An identification function is disposed in the band, along with an Electronic Article Surveillance (EAS) function, that may be selected to be at least one of an electro-magnetic or acousto-magnetic segment. The identification function is typically a Radio Frequency Identification (RFID) device. The EAS function segment operates independently of the RFID device, so that the presence or absence of one or more EAS segments can be detected without affecting the RFID function operation. In one embodiment, multiple segments are disposed on the band, with at least one segment having a different characteristic physical property than at least one other segment. The multiple segments may be formed on an upper and lower surface of the band, such that they overlap with one another in a vertical plane.

Claims

1. An identification apparatus, comprising:

a band of material;

an identification device attached to said band and responsive to a first signal; and

at least one tamper segment attached to said band that is responsive to at least one of an electro-magnetic and acousto-magnetic second signal wherein said identification device functions independently of said tamper segment.

2. An apparatus as in claim 1 wherein said identification device is a Radio Frequency Identification (RFID) device.

3. An apparatus as in claim 1 wherein said tamper segment responds to radiation in a spectral band that in different from a spectral band to which said identification device responds.

4. An apparatus as in claim 1 wherein said tamper segment comprises an element selected from a group consisting of a Radio Frequency (RF) resonant circuit, a nano-resonant structure, a magnetic resonant material, and an acoustic resonant material.

5. An apparatus as in claim 1 wherein a cut through the band changes an electro-magnetic and/or acousto-magnetic response of said tamper segment.

6. An apparatus as in claim 1 wherein one or more tamper segments and said identification device span the entire length of the band.

7. An apparatus as in claim 1 wherein multiple tamper segments are disposed on the band.

8. An apparatus as in claim 7 wherein at least two tamper segments overlap one another.

9. An apparatus as in claim 7 wherein at least one tamper segment has a different characteristic response than at least one other taper segment.

10. An apparatus as in claim 7 wherein at least two tamper segments are disposed on different surfaces of the band.

11. An apparatus as in claim 10 wherein at least two tamper segments are disposed on two different horizontal surfaces of the band, and are aligned with one another such that at least a portion of a first segment overlaps a portion of a second segment in at least one vertical plane.

12. An apparatus as in claim 1 wherein the tamper segments are selected from a group consisting of a wire loop, a tapered piece of material, or multiple material pieces.

13. A secure identification system, comprising:

at least one identification band comprising;

a band of material;

an identification device disposed on the band that is responsive to a first signal;

at least one segment formed along the identification band that is responsive to a second signal, wherein at least one segment functions independently of the identification device, and wherein at least one segment responds to the second signal differently after it has been altered; and

an interrogation device, for emitting the second signal to which the at least one segment responds.

14. A system as in claim 13 wherein the identification device is a Radio Frequency Identification (RFID) device comprising an antenna coupled to an integrated circuit.

15. A system as in claim 13 wherein the second signal is selected from a group consisting of a radio frequency wave, an electromagnetic wave, or an acousto-magnetic wave.

16. A system as in claim 13 wherein one or more segments and/or identification devices are disposed on said band to span substantially the entire length of said band.

17. A system as in claim 13 wherein said interrogation device also generates the first signal.

18. An identification apparatus, comprising:

a band of material;

a Radio Frequency Identification (RFID) device attached to said band, the RFID device being responsive to a first signal; and

at least one tamper segment, attached to said band, and formed of at least one of an electro-magnetic and acousto-magnetic material that is responsive to a second signal.

19. An apparatus as in claim 18 wherein said first signal has spectral properties that are different from said second signal.
