1. An information processing terminal, comprising:
- a data transmission unit;
a data storage unit configured to store data; and
an integrated circuit chip connected to the data transmission unit via a wired interface, wherein the integrated circuit chip is configured to be wirelessly communicable with a device in a noncontact manner, the integrated circuit chip comprising;
an integrated circuit wireless control block configured to;
start wireless communication with the device according to a signal carrier outputted from the device, andupon reception of a data transfer request signal, switch a communication mode of the integrated circuit chip to a continuous communication mode in which data can be continuously transmitted or received, thereby allowing data to be transmitted from the storage unit to the device without waiting for a predetermined command from the device.
