FIELD: radio engineering, communication.
SUBSTANCE: invention relates to wireless communication. The wireless data transmission device includes a transition unit for terminal data transmission, a terminal data transmission unit which transitions to a state in which communication with a data transmission terminal is possible in response to a transition instruction sent by the transition unit for terminal data transmission, a signal generating unit for generating a transition instruction signal, a transmission unit for wirelessly transmitting the transition instruction signal generated by the signal generating unit to an information processing device, a reception unit for wirelessly receiving a response from the information processing device to the transition instruction signal transmitted from the transmission unit, and a terminal data transmission control unit for starting to control information transmission/reception between the data transmission terminal and the information processing device according to the response received by the reception unit.
EFFECT: reducing power consumption by launching a read/write unit function in response to a user instruction.
