Abstract
According to one embodiment, according to one embodiment, an IC card executing a command from a processing apparatus includes a communication unit and a processing unit. The communication unit transmits/receives data to/from the processing apparatus. Upon receiving, through the communication unit, a first command requesting transmission of data in a first frame not including a start code or an end code, the processing unit transmits data in the first frame through the communication unit.
Claims13
An IC card that executes a command from a processing apparatus, the IC card comprising:
- an interface that transmits and receives data to and from the processing apparatus;
- a processor that transmits, through the interface, data in a first frame not comprising a start code or an end code upon receiving, through the interface, a first command requesting transmission of data in the first frame;
- and
- a storage unit that stores a flag indicating whether the start code and the end code are necessary or not;
- wherein the processor:
- sets, in the flag, a value indicating that the start code and the end code are unnecessary upon receiving the first command;
- transmits data in the first frame to the processing apparatus if the value indicating the unnecessity of the start code and the end code is set in the flag;
- and
- transmits data in a second frame comprising the start code upon receiving a second command requesting the start code through the interface;
- and
- the second frame does not comprise the end code.
