<p>The present invention relates to communication systems and methods which allow the partner of communication to be easily specified. A portable telephone 52 is provided with a non-contact IC card which communicates with a reader/writer of a personal computer 51 by electromagnetic waves. When the non-contact IC card receives electromagnetic waves emitted by the reader/writer, the portable telephone 52 reports the card ID assigned to the non-contact IC card to the personal computer 51. The card ID includes the Bluetooth address of the portable telephone 52. When the personal computer 51 obtains the Bluetooth addresses of the portable telephone 52 and a PDA 53 at an inquiry, the personal computer 51 specifies the portable telephone 52 as a Bluetooth device with which synchronization is established, according to the Bluetooth address reported in advance. The present invention can be applied to information processing apparatuses such as personal computers and portable telephones.</p> |
