Abstract
A tamper indication device has a film attached and connected within the circuit that generates a signal in response to a tamper event. The tamper indication device can be incorporated into a bullet proof vest. The sensor circuit in the bullet proof vest does not only detect a bullet strike but also determines the location of the strike base in the sensor zone where the sensor zone has been struck. This circuitry includes a cell phone module with a built in GPS sensor for supplying GPS coordinates and communicating by dispatcher with the vest wearer's name and other identifying information.
