This disclosure generally relates to the field of security tags, and more particularly, to a system, device, and method for removing a hard tag by utilizing a mobile detacher. A detacher key is inserted into the security device and rotated to release a pin, securing the merchandise to the device, from the device. The detacher key or device may include a cam of which is rotated to apply sufficient force on a retaining clip to release the pin from the clip to remove the pin out of the tag.

A magnetic decoupling unit (12) that is capable of magnetically releasing several types of magnetically releasable antitheft devices may include a magnet assembly (28). The magnet assembly (28) may be placed inside a magnet housing (20) with a cover (22) that has an aperture (24) and insert (26) for receiving portions of a magnetically releasable antitheft device. The magnet assembly (28) may include a first magnet (E) with a vertical magnetic orientation which is surrounded by adjacent magnets (B2, D, F1, F2) with magnetic orientations that are orthogonal to the vertical magnetic orientation. Additionally, the magnet assembly (28) includes one or more additional magnets (B1, C) oriented in the vertical and orthogonal directions. The resulting magnet assembly (28) may be capable of magnetically releasing single clutch, double clutch, and electronic media type antitheft devices.
