Data communication system, device for executing IC card function, control method for the device, and information processing terminal |
摘要 |
An information processing terminal defines a data transfer state for permitting a contactless data communication through an IC card and a data not transfer state for not permitting the contactless data communication so that the IC card manages the communication state of the information processing terminal. The IC card can transfer data to the terminal side depending on whether it is in any of the data transfer state and the data not transfer state without depending on the notification from the information processing terminal, synchronization can be easily established, a transfer speed can be increased, and a large amount of data can be transmitted. |
