<p>In a system for serially transmitting data between a card reader/writer and an IC card, when a data string is transmitted from the card reader/writer to the IC card, the data row is divided into a plurality of data strings (a). Data (control code) representing continuity of data transmission is added to each of the divided data strings. When a data string is transmitted from the IC card to the card reader/writer, the data string is divided into a plurality of data strings. IC card encodes the divided data string, and transmits the encoded data with the data (control code) representing continuity of data transmission (b) encoded data string. Data transmission between the card reader/writer and the IC card is controlled such that the divided data string and encoded data string are alternately transmitted in units of one. <IMAGE></p> |
