Abstract:
1. 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 operatively positioned adjacent each other, the system comprising a reader circuit and tag circuit: the reader circuit operatively connected to the first device and having a receiver coil and a transmit coil for providing oscillation energy to the tag circuit when the tag circuit is coupled to the reader circuit and for receiving coded information within the tag circuit and delivering the coded information to the microcontroller; the tag circuit for placement adjacent the reader circuit, the tag circuit having a tag coil for patterned oscillation at least two discrete frequencies and for coupling to the reader circuit such that the receiver coil, transmit coil and tag coil all oscillate at the same frequency when the reader circuit and tag circuit are coupled, the patterned oscillation representative of coded information within the tag circuit.
