A merchandise security device is provided. The merchandise security device may include a lock mechanism operably engaged with a shape memory material configured to receive electrical power for locking and unlocking the lock mechanism. The shape memory material may be configured to change in shape in response to receiving electrical power to thereby lock or unlock the lock mechanism.

A shelving rack system with a wireframe base and at least one wireframe divider having a rear hook that is received into an aperture on a rear support and a front leg that is received down into an aperture on a front support. The divider is locked into position by first pulling the divider forwards such that the rear hook locks in position and then rotating the divider downwards such that front leg locks into position. Next, a front stop bar is inserted through aligned apertures on a front bracket on the divider, a locking column on one side of the wireframe base and a side support column on an opposite side of the wireframe base. Finally, a fastening pin is inserted down into the locking column to secure the front stop bar into a locked position.

Systems and methods for operating a security tag. The methods involve: establishing an electrical connection between the security tag and an external Power Removal Station (PRS); performing operations by the security tag to authenticate a detach command sent from the external PRS; allowing power to be supplied from the external PRS to an electro-mechanical component of the security tag when the detach command is authenticated; and actuating the electro-mechanical component so that a pin of the security tag transitions from an engaged position to an unengaged position without any human assistance or mechanical assistance by a device external to the security tag.

A system for managing the unlocking of a device for identifying a commercial item includes at least two elements capable of assuming a locked position in which they enclose the article between them, and an unlocked position. The system includes a device for unlocking the identification device, elements for preventing unlocking, which are activated, and decision elements for deciding whether to deactivate or not deactivate the elements for preventing unlocking. The decision elements are capable of deciding on the basis of the identification or lack of identification of the association of the identification device and the commercial item to which the device is attached.

An anti-theft device for securing an article of merchandise against unauthorized removal from a display counter. A clip securely holds the article of merchandise. The clip has a hook on a bottom surface thereof. A base has an aperture configured to receive the hook. When the hook is inserted into the base through the opening, the clip is shifted relative to the base such that the point of the hook resides underneath a top plate of the base. A locking member immobilizes the clip within the base preventing the hook from becoming realigned with the base. A key is used to retract the locking member to release the clip from the base.

A merchandise security system for protecting an item of merchandise from theft. The merchandise security system comprises a smart device and an electronic key coupled to the smart device. The electronic key is configured to communicate with a merchandise security device for operating a merchandise security device.

A key for a security device is provided. The key may include an electronic component configured to communicate with one or more security devices to initially receive one or more codes associated with each of the security devices. The key may also include a memory configured to store the one or more codes associated with the one or more security devices. The electronic component is configured to communicate with each of the one or more security devices for arming and/or disarming the security devices upon a matching of the code stored by the memory with the code associated with the security device.
