ABSTRACT:
An apparatus for turning on and off, selectively, a piece of equipment and processing data pertaining thereto comprises a mechanical key adapted to interfit with a key receptacle provided at equipment to be secured, wherein movement of the key receptacle by the key is operative selectively to enable or disable operation of the machine. An integrated circuit including a solid state memory is provided within the key for processing electrical signals, and electrical contacts positioned on a periphery of the key are in contact with the integrated circuit and with corresponding electrical contacts in the receptacle. When the key is inserted into the receptacle and rotated to turn on the equipment, data transfer is established between the integrated circuit within the key and circuitry within the equipment. An identification card containing information corresponding to information stored in the integrated circuit is coupled to the key by a cord.
