Abstract
A security tag having a strap for securing the tag to an object to be protected-and an electronic module connected to the strap for detecting an attempt to defeat the tag by short circuiting and severing the strap. The strap is formed of plural discrete conductors connected to the electronic module, which conductors are insulated from each other at least along a substantial length of the strap. Short circuiting of opposite ends of a single pair of the conductors followed by severance of plural ones of the insulated conductors, or short circuit in between separate conductors can be detected by the electronic module as an alarm condition. Severance or misconnection of only one or a small number of the insulated conductors can be detected by the electronic module as not being an alarm condition.
Claims (9)
1. A security tag comprised of a module to which a strap is to be connected, and strap attachment points to the module offset from a center of the module wherein an axis of the strap is offset toward one edge of the module.
2. A security tag as defined in claim 1, in which the strap attachment points are located so as to position one edge of the strap along a line extending from approximately an edge of the module.
3. A security tag as defined in claim 1 or 2, including a strap having at least one elongated conductor embedded therein connected via the attachment points to a tamper detector within the module.
4. A security tag as defined in claim 3, including an electrical connector coupled to the tamper detector located at at least one attachment point.
5. A security tag as defined in any one of claims 1 to 4, in which the strap is formed of plural discrete conductors connected to the electronic module which conductors are insulated from each other along at least a substantial length of the strap, wherein short circuiting of opposite ends of a single pair of the conductors followed by severance of plural ones of the insulated conductors, or short circuiting between various separate insulated conductors can be detected by the electronic module as an alarm condition, and wherein severance or misconnection of one or a small number of the insulated conductors is detected by the electronic module as not being an alarm condition.
6. A security tag as defined in any one of claims 1 to 5, in which the shape of the electronic module has one edge of a substantially plane or slightly concave surface which has a large radius which extends between substantially opposite sides of said surface, the module having attachment points for the strap at locations adjacent opposite ends of said large radius edge.
7. A security tag as defined in any one of claims 1 to 6 in which the strap attachment points are located on opposite sides of an extension of a module which extension has substantially smaller lateral dimension than the lateral width of the remainder of the module.
8. A security tag comprised of a module to which a strap is to be connected, the shape of the electronic module having one edge to a substantially plane or slightly concave surface which has a large radius which extends between substantially opposite sides of said surface, the module having attachment points for the strap at locations adjacent opposite ends of said large radius edge.
9. A security tag as defined in claim 8, in which the strap is formed of plural discrete conductors connected to the electronic module which conductors are insulated from each other along at least a substantial length of the strap, wherein short circuiting of opposite ends of a single pair of the conductors followed by severance of plural ones of the insulated conductors, or short circuiting between various separate insulated conductors can be detected by the electronic module as an alarm condition, and wherein severance or misconnection of one or a small number of the insulated conductors is detected by the electronic module as not being an alarm condition.
