An antitheft device attachable to an article, formed by two parts, one part comprises a means for remote interaction with a terminal detecting passage of the device, a hinge to allow movement between a protection position, and a release position, one of the parts having, at the end opposite to the movable hinge, a needle able to move in a direction perpendicular to the mid-plane of the device, the other part comprising a housing for receiving the needle, the housing comprising lock configured to allow the release of the needle with an opener, wherein the first part has three retractable cages enabling the needle to move between a retracted position where the tip of the needle does not project beyond the internal surface of the first part, and a deployed position in which the needle is engaged in the complementary housing when the device is in the closed position.

The invention provides an RFID circuit for use with new or pre-existing antitheft tags. An RFID pin replaces the current pin on antitheft tags that retailers already own. The RFID circuit is incorporated into or secured to, the pin structure. By replacing the current pin used on antitheft tags with a low cost RFID pin, existing antitheft tags can be inexpensively upgraded to antitheft tags that are also capable of use as inventory management and/or enhanced theft control devices.

A theft deterrent device includes a locking portion and a housing portion. The locking portion includes a locking mechanism. The housing portion includes a housing portion wall. The housing portion wall comprises a first material and is configured to house a second material within the housing portion wall. The second material is made of a different material than the first material. The second material is selected such that a cutting tool will be hindered when trying to cut through the housing portion.

A pressurized chemical theft deterrent device includes a locking portion and a shackle. The locking portion includes a locking mechanism. The shackle includes a shackle wall. The shackle is configured to house a chemical deterrent within the shackle wall. The chemical deterrent is pressurized while being housed inside the shackle such that a breach in the integrity of the shackle wall causes an aerosolized release of the chemical deterrent.
