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. The example security device may also include a signal emitting component, a QR code, a barcode, or combination thereof.

An anti-theft device for an item having a peripheral shoulder, comprising two hinged portions each having a peripheral skirt provided with an edge capable of abutting under the peripheral shoulder, with the portions being hinged relative to a peripheral pivot; magnetically deactivatable locking means, which lock the two hinged portions in the closed position, and a detection means wherein the portions are made up of a stationary shell having a general cylindrical shape, the cross-section of which matches the cross-section of the item to be protected and a movable shell connected by a pivot, the stationary shell having a recess opening laterally to allow the insertion of the movable shell in closed position.

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.

An apparatus for locking an electronic device includes an actuator, a return mechanism, and an arm. The actuator includes an actuator SMM wire that is configured to apply a contraction force. The return mechanism includes a return SMM wire that is configured to apply a return force opposite the contraction force. The arm is movable toward an unlocked position by the actuator and movable toward a locked position by the return force. The arm has at least one equilibrium position with less than 1 Newton of force on the arm from the actuator and less than 1 Newton of force on the arm from the return mechanism.

A tag for attaching to an item such as a bag containing goods is disclosed. The tag has two body portions each of which have a gripping portion for gripping the bag. The body portions are adapted to move the gripping portions towards and away from each other between a gripping condition for gripping the bag without piercing it and an open condition in which the bag can be inserted into and removed from the tag. There is also a locking device in the form of a pin and magnetic clutch which allows the tag to lock in the closed position and then be released by a magnetic release device.

An EAS tag has a housing and a shackle. The shackle has a first segment with a first end and a second segment with a second end. The first segment of the shackle is slidably mounted in the housing while the second segment moves in and out of the housing in accord with the first segment. When the second segment is out of the housing, the shackle can be placed through an aperture in an object to be protected or around a portion of an object to be protected. The shackle is then slid into the housing so that the second segment inserts into the housing. A clutch within the housing prevents the shackle from being shifted until the clutch is released. The housing carries at least a passive EAS element. More advanced EAS electronic elements may also be carried in the housing.

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 electronic antitheft device comprising an electronic detection device, a first part and a second part, each part provided with an inner contact surface, and the first part being movable relative to the second part in such a way as to cooperate by clamping at the respective contact surface thereof. At least one of the parts, preferably both parts, comprise on the contact surface thereof an abrasive covering.

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.

A magnetic unlocking device and a magnetic unlocking structure of a magnetic encoding key. The magnetic unlocking structure includes a lock core device and a magnetic unlocking device. The lock core device includes a lock core casing, a lock knob which is provided in the internal cavity of the lock core casing, a lock care front end cover and a lock core rear end cover that are located at both ends of the lock core casing. The internal wall of the lock core casing is provided with a monad longitudinal moving groove and a monad horizontal rotating groove. The lock knob is provided with an unlocking hole. The external wall of the lock knob is provided with a monad longitudinal slide-way. The monad longitudinal slide-way and the monad longitudinal moving groove correspond to each other and form a monad moving cavity.
