ABSTRACT:
This invention relates to improvements in the functional design of electrical key-like devices and electrical receptacles for use in combination therewith. Electronic circuitry systems, such as computers and other operating circuits, interface with the key-like devices through the receptacle. The keys contain a microelectronic circuit element, e.g., a microelectronic circuit chip or die, having an electrical lead or leads exposed along the length of the key for contacting electrical leads in the receptacle when the key is inserted therein and rotated to a "locked" position. The keys are particularly designed to interface with a processor and program memory system, that is, a computer.
