A security tag, comprising:
- an attachment end having a first compartment to hold a tack retaining system, said tack retaining system to include a wedge and a rubber spring arranged to retain a tack assembly, and to release said tack assembly when said attachment end is exposed to a magnetic field;
- and
- a detection end having a second compartment to hold an electronic article surveillance sensor,
- wherein said wedge to have a first end and a second end and is positioned to pivot around said second end, and said spring is positioned to bias said first end against a wedge stop of said first compartment.
A tack retaining system, comprising a first compartment having disposed therein a wedge and a rubber spring, said rubber spring arranged to bias said wedge to retain a tack assembly, and to release said tack assembly when an attachment end is exposed to a magnetic field,
- wherein said wedge to have a first end and a second end and is positioned to pivot around said second end, and said spring is positioned to bias said first end against a wedge stop of said first compartment.
A magnetic detaching device, comprising:
- a magnet to generate a magnetic field;
- and
- a housing to house said magnet, said housing to include a detacher interface to correspond to a tag interface for a security tag having a tack retaining system, said tack retaining system to include a wedge and a rubber spring arranged to retain a tack assembly, and to release said tack assembly when an attachment end is exposed to said magnetic field,
- wherein said wedge to have a first end and a second end and is positioned to pivot around said second end, said spring is positioned to bias said first end against a wedge stop of a first compartment.
