Abstract
A wrist unit includes a transmitting circuit capable of producing coded radio frequency signals. The wrist unit when worn by the user applies the encoded radio frequency signals to the users body and causes the encoded signal to propagate through the users body as a transferring medium. A cooperating device includes a receiving contact which the user touches to impart the body signal. A receiver and decoder within the cooperating device identify the user and enable a gate circuit which in turn opens access to the user of the microprocessor and cooperating circuitry within the unit. In the absence of a code match, the access to the cooperating device is refused.
