Abstract

An alarming electronic article surveillance (“EAS”) tag for securing an item of merchandise includes an EAS sensor, a radio frequency identification (“RFID”) logic block, an alarm transducer, and an alarming tag processor. The RFID logic block includes a transceiver, a memory and a processor. The transceiver operates to receive a first interrogation signal. The memory includes a first identifier associated with the alarming EAS tag and a second identifier associated with the item of merchandise. The processor is operable to send a first trigger signal responsive to the transceiver receiving the first interrogation signal. The alarming tag processor is electrically coupled to the RFID logic block and the EAS sensor. The alarm transducer is operable to produce at least one of a visual indicator and an audible indicator based on the EAS sensor and the alarming tag processor.

2. The alarming EAS tag of claim 1, wherein the second identifier is one of a Uniform Product Code (“

UPC”

), an Electronic Product Code (“

EPC”

), and a Stock-keeping unit (“

SKU”

) code.

3. The alarming EAS tag of claim 1, wherein the first interrogation signal includes an identifier matching the first identifier, the processor is further operable to send the first trigger signal responsive to determining that the identifier in the interrogation signal matches the first identifier.

4. The alarming EAS tag of claim 1, wherein the transceiver is further operable to transmit a response signal, the response signal including at least one of the first identifier and the second identifier.

5. The alarming EAS tag of claim 1, further comprising a battery in communication with the RFID logic block;

and

the alarming tag processor is operable to;

receive the first trigger signal; and

responsive to receiving the first trigger signal, enter one of an active mode and a configuration mode, the active mode triggering the RFID logic block to operate using power supplied by the battery.

6. The alarming EAS tag of claim 5, wherein the alarming tag is unarmed prior to receiving the first trigger signal.

7. The alarming EAS tag of claim 5, wherein the alarming EAS tag further comprises at least one tampering sensor, when the alarming tag processor enters the active mode, the alarming tag processor is further operable to:

monitor the at least one tampering sensor; and

responsive to detecting that the at least one tampering sensor has been triggered, activate the alarm transducer.

8. The alarming EAS tag of claim 7, wherein the transceiver is further operable to receive a second interrogation signal:

the alarm processor is further operable to send a second trigger signal responsive to the transceiver receiving the second interrogation signal; and

the alarming tag processor is further operable to;

receive the second trigger signal; and

responsive to receiving the second trigger signal, activate the alarm transducer.

9. The alarming EAS tag of claim 7, wherein the transceiver is further operable to receive a second interrogation signal:

the alarm processor is further operable to send a second trigger signal responsive to the transceiver receiving the second interrogation signal; and

the alarming tag processor is further operable to;

receive the second trigger signal;

responsive to receiving the second trigger signal, monitor the EAS sensor; and

responsive to receiving an EAS alarm signal, activate the alarm transducer.

10. The alarming EAS tag of claim 1, wherein the alarming tag processor is further operable to adjust an alarming tag parameter.

11. The alarming EAS tag of claim 10, wherein the alarming tag parameter includes at least one of an alarm tone volume, an alarm tone type, an EAS protocol type enablement, a sensor sensitivity, the first identifier, the second identifier, and an alarm tone enablement.

12. The alarming EAS tag of claim 1, further comprising a battery in electrical communication with the alarming tag processor, wherein the alarming tag processor is further operable to read a battery charge condition.

13. The alarming EAS tag of claim 1, wherein the alarming tag processor is further operable to trigger a diagnostic routine.

14. The alarming EAS tag of claim 1, wherein the RFID logic block is further operable to download firmware to the alarming tag processor.

15. The alarming EAS tag of claim 1, further comprising a battery in communication with the RFID logic block, the first interrogation signal triggering the RFID logic block to operate using power supplied by the battery.

16. The alarming EAS tag of claim 1, wherein the first interrogation signal initiates monitoring of at least one tamper sensor;

and

the transceiver is further operable to receive a second interrogation signal, the second interrogation signal initiates monitoring of the EAS sensor.

17. A method for securing an item of merchandise using an alarming electronic article surveillance (“

EAS”

) tag, the alarming EAS tag including an alarming processor electrically coupled to a radio frequency identification (“

RFID”

) logic block, to an EAS sensor, to at least one tampering sensor and to an alarm transducer, the RFID logic block having a first identifier associated with the alarming EAS tag and a second identifier associated with the item of merchandise, the method comprising;

receiving a first interrogation signal;

responsive to receiving the first interrogation signal, sending a first trigger signal to the alarm tag processor;

receiving the first trigger signal; and

responsive to receiving the first trigger signal, monitoring the at least one tampering sensor; and

responsive to detecting that the at least one tampering sensor has been triggered, activating the alarm transducer to produce at least one of a visual indicator and an audible indicator based on the EAS sensor and the alarming tag processor.

18. The method of claim 17, further comprising:

determining that the first interrogation signal includes an identifier matching the first identifier; and

sending the first trigger signal responsive to determining that the identifier in the interrogation signal matches the first identifier.

19. The method of claim 18, further comprising:

transmitting a response signal, the response signal including at least one of the first identifier and the second identifier.
