Automatic touch identification system and method thereof

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.

I claim: 
     
         1 . An identification system for transmitting or receiving information via a user, comprising:
 an identification device for transmitting identifying information via the user, wherein the identification device includes a first coupling module configured to couple the identification device to the user by a capacitive type connection or a galvanic type connection, and   a reading device for receiving the identifying information from the identification device via the user, wherein the reading device includes a second coupling module configured to couple the reading device to the user by a capacitive type connection or a galvanic type connection,
 wherein size or shape of a coupling plate of the first coupling module or the second coupling module, and a carrier frequency used to transmit the identifying information to the reading device via the user are selected such that communication between the identification device and the reading device is based on a capacitive type connection or a galvanic type connection to the user without relying upon radiation of a communication signal.
