Abstract
An automatic identification system for communicating identifying information by coupling signals through the human body is provided. The system includes a battery powered identification device that transmits an identifying signal via a modulated carrier. The identification device is coupled to the body of the user via a coupling plate. The signal from the identification device is received by a reading device that is also coupled to the body of the user via a coupling plate. The reading device may display and/or enunciates the identifying information to the user. The coupling technique, carrier frequency, and construction of the devices are such that the identification information is not inadvertently radiated or coupled to unintentional users or receivers.
