Abstract: An identification (ID) module for use with a mobile platform, such as an aircraft, which forms a part of the aircraft installation, and which can therefore not be readily removed from the aircraft once installed. In one preferred form the ID module is mechanically and electrically coupled to an ARINC 600 connector.
