Abstract

An IC card has a communication unit, a storage unit, and a controller. The communication unit communicates with an external apparatus. A communication buffer for communication between the communication unit and the external apparatus is set in the storage unit. If the size of a buffer used in communication is designated by the external apparatus, the controller sets a receive buffer that stores reception data and a transmit buffer that stores transmission data in the communication buffer, and notifies the external apparatus of the size of the set receive buffer and the size of the set transmit buffer.
