Abstract
An apparatus and method are disclosed for a software and hardware configuration that uses inductive coupling to allow a physical object to determine information describing another physical object. An inductor capacitor circuit acts as a transmitter as well as a receiver of inductive field. A voltage signal provided to an inductor in an object causes the inductor to generate inductive field received by another inductor in a second object. An object receiving inductive field from another object analyzes the inductive field to receive arbitrary data, including but not limited to data that can allow the receiving object to determine the identity of the object transmitting the inductive field. The object receiving the inductive field can also determine the distance between the receiving object and the transmitting object based on the strength of a signal generated by the inductive field.
