    • An IC card transmits data received from a card reading and writing apparatus to a portable terminal via an external interface without changing the received data, or after the received data is converted according to an appropriate conversion scheme or is converted into other packet data. Conversely, the IC card transmits data received from the portable terminal via the external interface to the card reading and writing apparatus via a non-contact interface without changing the received data, or after the received data is converted according to an appropriate conversion scheme or is converted into other packet data. Therefore, non-contact data communication can be performed between the information processing terminal connected to the IC card and the card reading and writing apparatus.
    • IC卡经由外部接口将从卡读写装置接收的数据发送到便携式终端,而不改变接收到的数据,或者在根据适当的转换方案转换接收到的数据之后,或者将其转换为其他分组数据。 相反,IC卡经由外部接口将从便携式终端接收的数据经由非接触式接口发送到卡读写装置,而不改变接收到的数据,或者在根据适当的转换方案转换接收的数据之后,或者 转换为其他数据包数据。 因此,可以在连接到IC卡的信息处理终端和卡读写装置之间执行非接触数据通信。
