Abstract

An apparatus for turning on and off, selectively, a facsimile machine or other secured piece of equipment and processing data pertaining thereto comprises a key formed of a module and having stereo plugs extending therefrom adapted to interfit with stereo jacks in the equipment. An integrated circuit including a solid state memory is provided in the module for processing electrical signals. Data transfer is established between the integrated circuit in the module and circuitry in the equipment when the key is inserted in the equipment. In a preferred embodiment, the key is adapted to authorize and log financial transactions between parties via facsimile machines. An identification card containing information corresponding to information stored in the integrated circuit is coupled to the key by a cord.
