Abstract

Systems (100) and methods (800) for operating a security tag. The methods involve: coupling the security tag to an article by at least partially inserting an attachment assembly into a tag body; performing core security tag functions by a first electronic circuit disposed within the tag body of the security tag to protect the article from an unauthorized removal of the article from an area; and performing at least one first peripheral security tag function by a second electronic circuit disposed within the attachment assembly of the security tag.

Claims

1. A method for operating a security tag, comprising:

coupling the security tag to an article using an attachment assembly at least partially inserted into a tag body;

electrically connecting a first electronic circuit disposed in the tag body to a second electronic circuit disposed within the attachment assembly via a first conductive portion of an elongate tack body extending down and away from a tack head of the attachment assembly;

supplying power between the attachment assembly and the tag body using a second conductive portion of the elongate tack body that is spaced apart and insulated from the first conductive portion of the elongate tack body;

providing a ground connection between the tag body and the attachment assembly using a third conductive portion of the elongate tack body that is spaced apart and insulated from the first and second conductive portions of the elongate tack body;

performing at least one of a plurality of core security tag functions by the first electronic circuit disposed within the tag body of the security tag to protect the article from an unauthorized removal of the article from an area, the plurality of core security tag functions comprising an Electronic Article Surveillance (“

EAS”

) function and a Radio Frequency Identification (“

RFID”

) function; and

performing at least one first peripheral security tag function by the second electronic circuit disposed within the attachment assembly of the security tag.

2. The method according to claim 1, wherein the first peripheral security tag function is selected from a plurality of peripheral security tag functions based on an application-specific criteria.

3. The method according to claim 2, wherein the application-specific criteria comprises cost of security tag fabrication, security tag disposability, security tag utilization flexibility, and security tag power saving capability.

4. The method according to claim 1, wherein the first peripheral security tag function further comprises at least one of power supply functions, power supply monitoring functions, environmental sensor functions, sensor network transceiver functions, energy harvesting functions, user interface functions, alarm functions, and tamper detection functions.

5. The method according to claim 1, wherein at least one of a battery, a battery monitoring circuit, a sensor circuit, an energy harvesting circuit, and an alarm circuit is disposed within a tack head of the attachment assembly.

6. The method according to claim 1, further comprising performing at least one second peripheral function by a third electronic circuit exclusively coupled to the attachment assembly when the security tag is not coupled to the article.

7. The method according to claim 6, further comprising creating a closed circuit between the second and third electronic circuits when the security tag is coupled to the article, and creating an open circuit between the second and third electronic circuits when the security tag is decoupled from the article.

8. A system, comprising:

a security tag comprising a tag body and an attachment assembly that can be at least partially inserted into a tag body so as to couple the security tag to an article;

a first electronic circuit disposed within the tag body and configured to perform core security tag functions to protect the article from an unauthorized removal of the article from an area; and

a second electronic circuit disposed within the attachment assembly configured to perform at least one first peripheral security tag function;

wherein the attachment assembly comprises an elongate tack body configured to provide electrical connections between the tag body and the attachment assembly when the attachment assembly is at least partially inserted into the tag body; and

wherein a first one of the electrical connections is provided via a first conductive portion of the elongate tack body, a second one of the electrical connections is provided via second conductive portion of the elongate tack body that is spaced apart and insulated from the first conductive portion of the elongate tack body, and a third one of the electrical connections is provided via a third conductive portion of the elongate tack body that is spaced apart and insulated from the first and second conductive portions of the elongate tack body.

9. The system according to claim 8, wherein the core security tag functions include at least one of Electronic Article Surveillance (“

EAS”

) functions, Radio Frequency Identification (“

RFID”

) functions and tamper detection functions.

10. The system according to claim 8, wherein the first peripheral security tag function is selected from a plurality of peripheral security tag functions based on an application-specific criteria.

11. The system according to claim 10, wherein the application-specific criteria comprises cost of security tag fabrication, security tag disposability, security tag utilization flexibility, and security tag power saving capability.

12. The system according to claim 8, wherein the first peripheral security tag function further comprises at least one of power supply functions, power supply monitoring functions, an environmental sensor functions, sensor network transceiver functions, energy harvesting functions, user interface functions, alarm functions, and tamper detection functions.

13. The system according to claim 8, wherein at least one of a battery, a battery monitoring circuit, a sensor circuit, an energy harvesting circuit, and an alarm circuit is disposed within a tack head of the attachment assembly.

14. The system according to claim 8, further comprising a third electronic circuit configured to perform at least one second peripheral function, said third electronic circuit exclusively coupled to the attachment assembly when the security tag is not coupled to the article.

15. The system according to claim 14, wherein a closed circuit is created between the second and third electronic circuits when the security tag is coupled to the article, and an open circuit is created between the second and third electronic circuits when the security tag is decoupled from the article.
