Communication system and method

摘要

A communication system and method capable of easily identifying a communication mate. A cellular telephone (52) has a non-contact IC card communicating with a reader/writer of a personal computer (51) by an electromagnetic wave. When an electromagnetic wave radiated from the reader-writer is received by the non-contact IC card, the cellular telephone (52) reports the card ID set in the non-contact IC card to the personal computer (51). This card ID includes a Bluetooth address of the cellular telephone (52). When the personal computer (51) fetches the Bluetooth address of the cellular telephone (52) and a PDA (53) upon query, the personal computer (51) identifies the cellular telephone (52) as a Bluetooth device to establish synchronization according to the Bluetooth address reported in advance. The present invention can be applied to an information processing apparatus such as a personal computer and a cellular telephone.
