摘要 |
<p>An IC card capable of a high-speed data transmission to/from a data transmission apparatus which is low in processing capability, is provided. The IC card of the present invention comprises: a controlling section which generates a data packet by adding management information including information regarding a data length of the data packet, and which divides the above-mentioned data packet to generate data blocks wherein a data length of the data block is designated from the data transmission apparatus; and a communicating section which sends an interrupt signal to the above-mentioned data transmission apparatus when the above-mentioned data block which includes the above-mentioned management information is to be sent, and does not send the above-mentioned interrupt signal to the above-mentioned data transmission apparatus when a data block which does not include the above-mentioned management information is to be sent, in a case where a plurality of the above-mentioned data blocks which compose the single above-mentioned data packet are sent to the above-mentioned data transmission apparatus. <IMAGE></p> |
