PROBLEM TO BE SOLVED: To provide an IC card processor and an IC card that can more efficiently perform communication.SOLUTION: An IC card processor transmits a command to an IC card and causes the IC card to execute various processing. The IC card processor comprises: a first command generation section that generates a first command and adds a parity bit to each of units constituting the first command generated; a first transmission section for transmitting the first command to the IC card; a first reception section for receiving error information indicating a position on the first command having an error detected in a parity check executed by the IC card with respect to the first command; a second command generation section for generating a second command containing data of the position on the first command indicated by the error information; a second transmission section for transmitting the second command to the IC card; and a second reception section for receiving a response that is a result of the processing executed by the IC card on the basis of the first command and the second command. |
