Hard security tag and detaching device

DETAILED DESCRIPTION The embodiments may be directed to a security system.
The security system may be, for example, an EAS system.
The EAS system may comprise a security tag, a detaching device and monitoring system.
In general operation, the security tag may include a sensor to emit a detectable signal when it is in the monitored surveillance zone.
The security tag may be attached to an item, such as an article of clothing.
The detaching device may detach the security tag from the item.
The monitoring system may monitor a controlled area for the signal to ensure that the item with the security tag is not removed from the controlled area.
In one embodiment the security tag may be, for example, a hard security tag designed for single use.
The detaching device may detach the security tag from the item in a manner that damages the tag and prevents its reuse.
Since the security tag is designed for a single use, the cost of the security tag may be substantially reduced relative to conventional reusable hard security tags.
Consequently, the manufacturer, retailer and consumer may benefit from the reduced costs.
For example, in one embodiment the security tag may have a security tag with a clamp disposed within the housing.
The clamp may be flexible.
During the attachment operation, a tack body may be inserted through the article of clothing and into a hole in the security tag, and further into the retaining aperture of the clamp.
The tack body may be retained in the security tag by the clamp.
During the detachment operation, the detachment device may have one or more driver rods that penetrate the outer wall of the tag body in order to access and apply pressure to the clamp thereby releasing the tack body.
Once the tack body has been released from the clamp, the tack body may be removed from the security tag to detach the security tag from the item.
When the driver rods are withdrawn, the outer wall may be permanently deformed.
For example, the outer wall may have one or more holes or apertures
