Technical Examples

An apparatus and method for controlling user access to electrical receptacles and telephone and network communications receptacles. The device features a short range radio receiver and one or a plurality of RF energized radio identification tags with transmittable identification transponder codes. The receptacle contains circuitry that detects the immediate presence of energized transponders with proper identification codes and only enables the electric, telephone or network access from the receptacle to become active if the correct matching transponder identification code is present. The tag is a small flexible device having one side that may be attached to the plug or the receptacle or interfaced therebetween. Access to the power or network is allowed for a defined duration of time or only so long as the transponder remains energized and transmits the identification code.
