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.
