An anti-theft device comprises a notched strap having a free end and an end rigidly connected to a block, which locks the notched surface of the strap in the closed position when the free end is inserted into an insertion slot provided in the locking block. The anti-theft device further comprises theft detection means.

Embodiments of the present invention are directed to merchandise display systems and methods for displaying an article of merchandise. In one example, the system includes a sensor configured to be secured to the article of merchandise. The system also includes a base configured to removably support the sensor thereon. The base includes a lock mechanism configured to lock the sensor to the base.

An apparatus and method for unlocking a security tag that is connected to an article. The apparatus includes an unlocking device configured to provide an unlock signal or force to a security tag allowing for the security tag to be removed from the article. The apparatus further includes an outer housing having an unlocking surface at least partially disposed above the unlocking device, wherein the unlocking surface includes a continuous surface area defined by a first surface area connected to a second surface area. In one aspect, the second surface area is tactically distinct from the first surface area and the second surface area includes an alignment feature configured to indicate a detachment zone that corresponds with a source of the unlock signal or force.

Systems and methods for operating a tag. The methods comprise: actuating a telescoping actuator of the tag to transition a pin from an unengaged position in which the pin is retracted into a first portion of the tag's housing to an engaged position in which the pin extends through an insert space and into a second portion of the tag's housing; and mechanically securing the pin in the engaged position using a securement mechanism disposed in the second portion of the tag's housing. The pin is securely coupled to a movable component of the telescoping actuator so as to be integrated into the tag's body, and the first and second portions of the tag's housing are coupled to each other so as to form a unitary piece.

An apparatus and method for unlocking a security tag that is connected to an article. The apparatus includes an unlocking device configured to provide an unlock signal or force to a security tag allowing for the security tag to be removed from the article. The apparatus further includes an unlocking surface disposed between the unlocking device and the security tag and an alignment feature configured to indicate a detachment zone that corresponds with a source of the unlock signal or force, wherein placing the tag in the detachment allows for the unlocking device to provide an unlock signal or force to the security device to allow the security tag to be removed from the article.

A security tag including: a housing and circuitry which detects a locked state, the circuitry configured to execute a signal transfer function responsive to interchanging a pin and a lanyard in the circuitry, and/or the housing including a replaceable battery compartment locked by inserting either the pin or the lanyard into a lock mechanism which differently secures the pin and the lanyard; and an alarm, in communication with the circuitry, triggered by an undisarmed breach of the locked state.

Systems and methods for operating a tag detacher. The methods comprise: receiving a tag body of a security device in a nest of the tag detacher; actuating a detachment mechanism of the tag detacher so as to cause a release of a tack assembly from a securement mechanism located within the tag body of the security device; allowing the tag body to travel out of a nest by at least rotating a portion of the nest so that the nest transitions between a home position and a pivoted position; and returning the nest to the home position when the tag body no longer resides in the nest.

Systems and methods for operating a security tag. The methods comprise: transitioning a pin head from an extended position to a collapsed position by causing at least one first telescoping segment to slidingly engage a second telescoping segment; locking a shaft, extending out and away from the pin head in the collapsed position, using a securement mechanism disposed inside a housing of the security tag; and preventing a transfer of pin head rotation to the shaft at least when the shaft is locked by the securement mechanism.

A security tag including: a housing and circuitry which detects a locked state, the circuitry configured to execute a signal transfer function responsive to interchanging a pin and a lanyard in the circuitry, and/or the housing including a replaceable battery compartment locked by inserting either the pin or the lanyard into a lock mechanism which differently secures the pin and the lanyard; and an alarm, in communication with the circuitry, triggered by an undisarmed breach of the locked state.

Example product security devices and associated methods are provided. An example product security device may include a first jaw and a second jaw that are operably coupled together to slide between an open position and a closed position. The example product security device may include a locking mechanism. In a locked state, the locking mechanism may permit movement of the first jaw towards the second jaw but prevent movement away from the second jaw. The example product security device may also include a product engagement pin. The product engagement pin may fasten the product security device to a product by piercing through the product and being received by the second jaw. A shroud having a shroud orifice may surround the product engagement pin and be operably coupled to the first jaw such that the shroud is movable relative to the product engagement pin.
