Abstract

<P>PROBLEM TO BE SOLVED: To provide a system and method of exchanging information, easily exchanging electromagnetic information of an electronic business card or the like in a power saving manner. <P>SOLUTION: Since electric field communication is used when exchanging business card information, the electronic business card is easily exchanged without setting the destination information of a mobile terminal of an opposite party or the like as before. Also, since a terminal management part is activated to exchange the business card information only in the case based on the opening/closing state of the mobile terminal and the ON/OFF state of a button and the terminal management part is returned to a pause state when the business card exchange is ended, the information exchange system with suppressed power consumption is provided. <P>COPYRIGHT: (C)2010,JPO&INPIT
