摘要： An information processing device includes a transmission portion that transmits repeatedly, at a specified time interval, one combination packet that is created such that it includes, within a packet that is compatible with one format, a packet that is compatible with another format. It is therefore possible for the information processing device to perform non-contact communication in a plurality of formats without repeatedly transmitting in succession a plurality of copies of the same packet, each copy being compatible with a different format.

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.

摘要： The present invention provides a portable information terminal having installed therein an IC chip. The portable information terminal includes an internal memory disposed within the IC chip driven by using power supplied via a reader/writer, which is impossible to be accessed from outside the IC chip, an external memory driven by using power from an external power source installed outside the IC chip and a data management unit that controls data write processing or data read processing executed to write data into or read data from the internal memory or the external memory in correspondence to the power supply state pertaining to the external memory. The data management unit selects data with a high access frequency or a high priority among a plurality of sets of data recorded in the external memory and records the selected data into the internal memory.

摘要： A client (such as a PC, portable telephone, PDA, electrical appliances), to which a device such as a IC card is connected, starts a handshake protocol to request a server to start communication. When communication is established via the handshake protocol, the initiative of communication is transferred to the server, and the state changes into a neutral state. In this neutral state, a control packet including a particular number of messages and a finished message is transmitted from the server to the client. If the client receives the control packet, the client performs a process according to the messages included in the control packet. This makes it possible to remotely control a device via a network in a highly reliable and efficient manner.
