CLAIMS

1. A tag attachable to an item, the tag including a flexible filament having at a first end a crossbar, the cross bar insertable in a bore of a needle, wherein the needle is pushable through the item, wherein the cross-bar is pushable inside the needle bore and through the item, the tag further comprising:

an electrical conductor routed along a length of the filament and into the cross-bar ; a substrate, mechanically attached to the filament at a second end of the filament;

an electrical circuit connected to the electrical conductor, wherein the substrate bears the electrical circuit, wherein the electrical circuit is configured to sense the state of the electrical conductor whether the electrical conductor is connected or severed.

2. The tag of claim 1, wherein the electrical conductor includes a loop routed through the length of the filament and into the cross-bar.

3. The tag of claim 2, wherein the electrical circuit is configured to determine electrical continuity between ends of the loop to detect thereby whether the state of the loop is connected or severed.

4. The tag of claim 1, further comprising:

an antenna connected to the electrical circuit, wherein the electrical conductor is at least a portion of the antenna.

5. The tag of claim 1, further comprising:

storage configurable to store identification information of the item.

6. The tag of claim 5, wherein the electrical circuit is configured to modulate a received electromagnetic signal with a datum indicating the identification information.

7. The tag of claim 5 or claim 6, wherein the electrical circuit is configured to receive a query signal and transmit in response an electromagnetic signal modulated with a datum indicating the identification information.

8. The tag of claim 1, further comprising at least one of:

an internal source of stored electrical energy and

a mechanism configured to harvest received radio-frequency electromagnetic radiation as an energy source.

9. The tag of claim 1, wherein the electrical circuit is configured to respond to a received query signal when a change of state is detected from connected to severed of the electrical conductor.

10. The tag of claim 9, wherein at least some of received energy of the query signal is transferred to the electrical conductor to determine the state of the electrical conductor.

11. The tag of claim 1, wherein the electrical circuit is configured to respond to a received query signal with a response signal regardless of the state of the electrical conductor, the response signal encoded with a datum indicating the state of the electrical conductor.

12. The tag of claim 1, wherein the electrical circuit is configured to not respond to a received query signal when the electrical conductor is connected and not severed.

13. The tag of claim 1, wherein the electrical circuit is configured to not respond to a received query when the tag already reported that the electrical conductor is severed.
