Abstract
An integrated circuit (IC) card capable of a high-speed data transmission to/from a data transmission apparatus having low processing capability. A controlling section generates a data packet by adding management information including information regarding a data length of the data packet, and divides the data packet to generate data blocks. The data length of the data block is designated from the data transmission apparatus. When the data blocks which compose the single data packet are sent to the transmission apparatus a communicating section sends an interrupt signal to the data transmission apparatus if the data block including the management information is to be sent, and does not send the interrupt signal to the data transmission apparatus if a data block not including the management information is to be sent.
