Abstract
Communications systems and methods can include wide area network communication capabilities provided by a communications module or device and additional functionality provided by one or more interchangeable devices that interface with the communications module. One or more of the interchangeable devices can communicate with the communications module or device via a short range wireless signal, such as for example that of an RFID, WiFi, or Zigbee system. Authentication of the communication device in combination with the one or more interchangeable devices can be included to provide device compatibility and security verification.
