Tag configured for interaction with security gate

1. A wireless identification tag configured to be triggered by an Electronic Article Surveillance (EAS) gate while remaining invisible to the EAS gate, the tag comprising:

at least one antenna tuned to receive energy transmitted in at least one of a first EAS gate frequency range of about 7-13 MHz or a second EAS gate frequency range of about 58-60 kHz, and configured to be non-detectable by the EAS gate when the at least one antenna detects an incident EAS field of the EAS gate;

at least one transmitter configured to send at least one identification signal;

at least one energy storage component, electrically connected to the at least one transmitter, for powering the at least one transmitter; and

at least one circuit connected to the at least one antenna and configured to:

detect energy transmitted from the EAS gate in at least one of the first EAS gate frequency range or the second EAS gate frequency range, and

in response to detecting the energy transmitted from the EAS gate, cause the at least one transmitter to transmit to a receiver other than the EAS gate, the at least one identification signal transmitted in a frequency outside the first EAS gate frequency range and the second EAS gate frequency range.

2. The wireless identification tag of claim 1 , wherein the frequency outside the first and second EAS gate frequency ranges is within a frequency range of 2.4 GHz world-wide industrial, scientific, and medical (WW ISM).

3. The wireless identification tag of claim 1 , wherein the at least one circuit is configured to cause the at least one transmitter to transmit the at least one identification signal less than ten seconds after the energy transmitted from the EAS gate is detected.

4. The wireless identification tag of claim 1 , wherein the at least one energy storage component is configured to store radio frequency energy received by the at least one antenna, the received radio frequency energy being characterized by a frequency outside of the first EAS gate frequency range and outside the second EAS gate frequency range.

5. The wireless identification tag of claim 1 , wherein the at least one antenna includes:

a first antenna tuned to receive energy transmitted within a frequency range of 900 MHz world-wide industrial, scientific, and medical (WW ISM);

a second antenna tuned to receive energy transmitted within a frequency range of 2.4 GHz WW ISM; and

at least one EAS antenna configured to receive the energy transmitted in the at least one EAS gate frequency range.

6. The wireless identification tag of claim 5 , wherein the at least one energy storage component is configured to store the energy received by the first antenna and the second antenna, and power the at least one transmitter with the stored energy.

7. The wireless identification tag of claim 1 , wherein the at least one transmitter is configured to send the identification signal via at least one of a Bluetooth protocol, Bluetooth Low Energy, Wi-Fi, ZigBee, Z-wave, or radio-frequency identification (RFID) protocol.

8. The wireless identification tag of claim 1 , wherein the at least one transmitter is configured to sequentially send a plurality of repetitions of the identification signal in response to detecting the energy transmitted from the EAS gate.

9. The wireless identification tag of claim 8 , wherein the at least one transmitter is configured to dynamically delay each of the plurality of repetitions of the identification signal, to thereby avoid signal collision.

10. The wireless identification tag of claim 8 , wherein the at least one transmitter is configured to randomly delay at least one of the repetitions of the identification signal, to thereby avoid signal collision.

11. The wireless identification tag of claim 1 , wherein the at least one transmitter is further configured to transmit at least one alert signal for causing at least one of an audible alert, a visual alert, or a digital message.

12. The wireless identification tag of claim 11 , wherein the at least one alert signal is a component of the at least one identification signal.

13. The wireless identification tag of claim 11 , wherein the at least one alert signal is separate from the at least one identification signal.

14. The wireless identification tag of claim 1 , configured for association with a specific product to thereby transmit a unique identification signal that differs from identification signals from tags associated with other instances of a same product.

15. The wireless identification tag of claim 1 , wherein the at least one circuit is configured to implement an identification transmission rule for regulating the at least one circuit in a manner causing the at least one transmitter to delay sending the identification signal, even when sufficient transmission power for transmitting the identification signal is aggregated and stored in the energy storage component.

16. The wireless identification tag of claim 15 , wherein the at least one circuit is configured to implement the identification transmission rule to cause the transmitter to send the identification signal in a predetermined time interval.

17. The wireless identification tag of claim 15 , wherein the at least one circuit is configured to implement the identification transmission rule to define a time interval between transmission of two consecutive identification signals.

18. The wireless identification tag of claim 15 , wherein the at least one circuit is configured to implement the identification transmission rule to randomly select a time interval between two consecutive identification signals.

19. The wireless identification tag of claim 1 , where the non-detectability of the at least one antenna enables the tag to avoid triggering the EAS gate.

20. The wireless identification tag of claim 1 , wherein the at least one circuit is configured to conserve energy by activating for a first predetermined length of time and deactivating for a second predetermined length of time, in a repeating manner.
