A security tag includes a tag body member, a connecting member releasably engageable with the tag body member, and a locking member having a locked position in a first thermal state configured to lock the connecting member to the tag body member, and having an unlocked position in a second thermal state configured to unlock the connecting member from the tag body member. The locking member includes a locking body comprising a shape memory alloy, and a clamping member connected to the shape memory alloy. A transition of the shape memory alloy element from the first thermal state to the second thermal state moves the clamping member from the locked position to the unlocked position, thereby enabling the connecting member to be detached from the tag body member.

A security apparatus is disclosed herein for securing a secured object to a tabletop of a display table or to another display surface. The security apparatus comprises a housing with a support surface for supporting the secured object. A pair of arm assemblies extend above the support surface and are configured to move between an open position where the secured object may be placed on or removed from the support surface. A mechanical drivetrain is provided for actuating the arm assemblies between the open and closed positions. When the security apparatus is attached to a tabletop of a display table, at least a portion of an actuator of the mechanical drivetrain will extend beneath the surface of the display table, which should be made inaccessible to the public.

Disclosed is a product anti-theft system having a product anti-theft device configured to be attached to a product to be secured, the anti-theft device having a housing with a connecting portion designed to be connected to the product to be secured and a locking mechanism associated with the connecting portion and having a secured state and a released state. The anti-theft system further includes a release device for transmitting a release signal that triggers transferring of the locking mechanism from the secured state to the released state. Also disclosed is a method of operating an anti-theft device.

A combined EAS and RFID circuit includes an HF coil antenna, a UHF tuning loop, and an RFID chip coupled to a strap that includes a first coupling area and a second coupling area. The coil ends of the HF coil antenna are configured to capacitively and/or conductively couple to one or both of the first coupling area or second coupling area of the strap. The HF coil antenna can include a gap between turns for non-interfering placement of the UHF tuning loop. The EAS circuit can be deactivating upon application of a field at the resonant frequency of sufficient intensity to cause the breakdown voltage to be exceeded between a coil end and coupling area. The threshold breakdown voltage between a coil end and a coupling area can be reduced by laser ablation treatment of a conductive surface of one or both of the coil end or coupling area.

A cooler access control system locks a cooler when occurrence of an event is detected that requires limiting access to the inside of the cooler. Examples of such events include the loss of power to the cooler for a predetermined period of time, the opening of the cooler door for longer than an allowed time, the loss of functionality of a temperature probe and others. In an embodiment, a service mode is supported wherein the door is left unlocked despite the occurrence of such an event, to allow a stocker or other personnel to leave the cooler door open while stocking the cooler with product.

This disclosure is directed to product merchandising systems that are designed to prevent brute force attempts to steal a product on display. The merchandising systems include security features that enhances the strength of the connection between a puck assembly and a base assembly and between the base assembly and a display surface. The merchandising systems are suited for withstanding brute force pulling attacks on the puck assembly and the base assembly.

Systems and methods for operating a security tag. The methods comprise: causing a plunger of the security tag to engage a latch of the security tag; preventing, by an anti-defeat structure of the security tag, a disengagement between the plunger and the latch when an impact force is applied to the security tag; and allowing, by the anti-defeat structure, the plunger to disengage the latch when a magnetic field is applied to the security tag.

Aspects of the present disclosure include methods, systems, and non-transitory computer readable media for receiving a confirmation signal to unlock the security tag from being locked to a merchandise, transmitting a RFID signal to the RFID device associated with the security tag to enable a controller to receive a release signal used to unlock the security tag from the merchandise, and transmitting the release signal to the controller to unlock the security tag from the merchandise.

An example electronic security tag attachable to an item includes a tag body member, a connecting member having a pin portion releasably engageable with the tag body member, the pin portion extending along a first axis. The electronic security tag further includes a locking member to lock the connecting member to the tag body member. The locking member includes a clutch mechanism movable along a second axis parallel to the first axis between a first position in contact with the pin portion and corresponding to a locked state and a second position corresponding to an unlocked state. The clutch mechanism including at least one member formed from a non-ferromagnetic material.
