Ic card, mobile electronic device and data processing method in ic card

A mobile electronic device comprising:

• a communication module configured to make contactless data communication with an external device,
• a first command processing module configured to perform a process corresponding to a first command received from the external device,
• a determining module configured to determine whether a second command is contained in a data portion of the first command,
• a second command processing module configured to perform a process corresponding to the second command if the determining module determines that the second command is contained in the data portion of the first command, and
• a response processing module configured to set a processing result of the second command executed by the second command processing module in the data portion of the response indicating a processing result of the first command executed by the first command processing module and transmit the same to the external device.

A data processing method of an IC card that makes contactless data communication with an external device, comprising:

• performing a process corresponding to a first command received from the external device,
• determining whether a second command is contained in a data portion of the first command,
• performing a process corresponding to the second command when it is determined by the determining that the second command is contained in the data portion of the first command, and
• setting a processing result with respect to the second command in the data portion of a response indicating a processing result of the first command and transmitting the same to the external device.
