A mobile communication device adapted to communicate with a plurality of pre-determined sources disposed at pre-determined different locations includes an identification code, a receiver adapted to receive wirelessly communicated information from a particular source at a pre-determined location, an orientation detector that detects the orientation of the receiver relative to the pre-determined location of the particular source to provide an orientation signal indicating that the mobile communication device is oriented toward the predetermined location of the particular source, and an interface circuit responsive to the wirelessly communicated information and the orientation signal to register the identification code with the particular source. |
