Abstract
A communication device is disclosed having optical and near-field communication capability. The device includes an optical transceiver circuit fabricated on an integrated circuit die and configured to transmit and receive far field signals. A near field transceiver circuit is also fabricated on the integrated circuit die and is configured to transmit and receive near-field electro-magnetic signals. Control circuitry is provided to selectively enable the optical transceiver circuit and the near field transceiver circuit responsive to an external control signal.
