Abstract
Techniques to release a security tag are described. One embodiment may comprise a tag housing, a tack body, and a linear clamp disposed within the tag housing to retain the tack body. The linear clamp may move in a substantially linear direction in response to force to release the tack body from the linear clamp. Other embodiments are described and claimed.

A security tag, comprising:
- a tag housing;
- a tack body;
- and
- a linear clamp disposed within said tag housing to retain said tack body, said linear clamp to move in a substantially linear direction in response to force to release said tack body from said linear clamp, said linear clamp to comprise:
- a clamp body having a slot at each end of said body;
- a spring arm attached to a first edge of said clamp body;
- and
- a tack retaining body to retain said tack body, said tack retaining body to comprise a first jaw and a second jaw, with each jaw terminating in spaced facing edges, said spaced facing edges forming an aperture and a law open area in said clamp body, and a second portion of said spaced facing edges are straight to form said jaw open area, with a first distance between a first end of said jaw open area being less than a second distance between a second end of said jaw open area.
