An inductive sensory system is provided. The system includes at least one object encoded with conductive material and a reader for use in detecting the presence or absence of the conductive material in the coded object. The reader includes a plurality of single coils and detection means for measuring changes in the self inductance of the coils due to the presence or absence of conductive material in the object. The sensory system further includes control means interconnected to the detection means. The control means are adapted to receive a signal from the detection means, translate the signal and generate a control signal for transmission to an external reactive member such as a light, sound or voice generator.
