<p>A wireless communication device that is attached or included in an electronic object, such as a portable computer, having its own separate communication system. The separate communication system has an antenna for receiving and transmitting wireless communication, and is powered by a power supply included in the object. Since the separate communication system can only communicate when powered, a separate passive wireless communication device is provided for wireless communication that does not require power from the power supply to communicate. The wireless communication device is interfaced with the existing antenna of the separate communication system so that the wireless communication device and separate communication system share a common antenna to reduce cost. The antenna may also be interconnected to a controller associated with the object so that the controller can directly communicate to the wireless communication device.
