ABSTRACT:
A tamper-proof security device for preventing the unauthorized removal of an individual or asset from a secured area and a system for use with the same is disclosed. The device is attached to an individual or asset and comprises a transmitter having a transmitter circuit therein for generating a digitally encoded signal on a predetermined frequency. At least one wire is disposed within the device for creating continuity in the transmitter circuit when the device is attached to the individual or asset. A power source is disposed within the transmitter which is electrically connected to the transmitter circuit when a switching mechanism is operated, thereby activating the transmitter circuit. Once the transmitter circuit is activated, the transmitter circuit generates the digitally encoded signal in response to a discontinuity in the wire.
