IC CARD, DATA TRANSFER DEVICE, DATA TRANSFER METHOD, AND DATA TRANSFER METHOD PROGRAM

摘要

An IC card capable of high-speed data transfer with a data transfer device with low processing capability. The IC card has a controller and a communication unit. The controller adds management information, including information on the data length of a data packet, to generate the data packet and divides the data packet into data blocks each having a data length equal to a size instructed by the data transfer device. When sending the plurality of data blocks of one data packet to the data transfer device, the communication unit sends an interrupt signal to the data transfer device when the data block including the management information is sent to the data transfer device but does not send the interrupt signal when the data block not including the management information is sent to the data transfer device.
