Alarming smart magnetic tag
Systems and methods for operating a security tag ( 132, 300 ). The methods comprise: wirelessly receiving at the security tag a signal sent from a remote device ( 104, 190 ); and preventing alarm issuance when first and second Magnetic Attracting (“MA”) halves ( 302, 312, 702, 704 ) of the security tag are pulled apart by deactivating alarm circuitry ( 264, 340 ) internal to the security tag in response to the security tag's reception of the signal.
1. A method for operating a security tag, comprising:
wirelessly receiving at the security tag a signal sent from a remote device; and
preventing alarm issuance when first and second Magnetic Attracting (“MA”) halves of the security tag are pulled apart by deactivating alarm circuitry internal to the security tag in response to the security tag's reception of the signal.
2. The method according to claim 1 , further comprising outputting an alert indicating that the security tag has not been decoupled from an article after the alarm circuitry's deactivation.
3. The method according to claim 1 , further comprising outputting an indication that the alarm circuitry has been deactivated so that a user knows when to pull the first and second MA halves of the security tag apart without alarm issuance.
4. The method according to claim 1 , wherein the signal is sent from the remote device when a successful purchase of an article has occurred.
5. The method according to claim 1 , wherein the alarm circuitry is deactivated by ceasing a supply of power to the alarm circuitry.
6. The method according to claim 1 , wherein the first and second MA halves are able to be manually pulled apart by a user without assistance from a dedicated security tag detacher device.
7. The method according to claim 1 , further comprising performing operations by the security tag, prior to preventing said alarm issuance, to authenticate an alarm deactivation command contained in the signal.
8. The method according to claim 1 , further comprising clamping an article between the first and second MA halves.
9. The method according to claim 1 , further comprising opening a switch disposed in the security tag by placing the first and second MA halves in proximity to each other.
10. The method according to claim 9 , further comprising causing alarm issuance by placing the first and second MA halves a certain distance apart whereby the switch is closed.
11. A security tag, comprising:
first and second Magnetic Attracting (“MA”) halves; and
an electronic circuit disposed in at least one of the first and second MA halves that is configured to
wirelessly receive a signal sent from a remote device, and
prevent alarm issuance when the first and second MA halves are pulled apart by deactivating alarm circuitry in response to the security tag's reception of the signal.
12. The security tag according to claim 11 , wherein the electronic circuit further causes an alert to be output indicating that the security tag has not been decoupled from an article after the alarm circuitry's deactivation.
13. The security tag according to claim 11 , wherein the electronic circuit further causes an indication to be output indicating that the alarm circuitry has been deactivated so that a user knows when to pull the first and second MA halves apart without alarm issuance.
14. The security tag according to claim 11 , wherein the signal is sent from the remote device when a successful purchase of an article has occurred.
15. The security tag according to claim 11 , wherein the alarm circuitry is deactivated by ceasing a supply of power to the alarm circuitry.
16. The security tag according to claim 11 , wherein the first and second MA halves are able to be manually pulled apart by a user without assistance from a dedicated security tag detacher device.
17. The security tag according to claim 11 , wherein the electronic circuit further performs operations, prior to preventing said alarm issuance, to authenticate an alarm deactivation command contained in the signal.
18. The security tag according to claim 11 , wherein the security tag is coupled to an article by clamping the article between the first and second MA halves.
19. The security tag according to claim 11 , wherein the electronic circuit comprises a switch that is opened by placing the first and second MA halves in proximity to each other.
20. The security tag according to claim 19 , wherein alarm issuance occurs when the switch is closed as a result of the first and second MA halves being placed a certain distance apart.
