Abstract
A system allowing the wireless transfer of data between a first device having a microcontroller and a second device when the first and second devices are positioned adjacent each other is described. The system includes a reader circuit and tag circuit. The reader circuit is operatively connected to the first device and provides oscillation energy to the tag circuit when the tag circuit is coupled to the reader circuit. The reader circuit receives coded information from the tag circuit and delivers the coded information to the microcontroller. The tag circuit includes a coil and logic enabling patterned oscillation at least two discrete frequencies such that the patterned oscillation is representative of coded information within the tag circuit. The system may be configured to a variety of product pairs, including consumer product pairs, to control the operation of the product pair or collect information about the operation of the product pair.
