    • An information-processing apparatus shown in FIG. 4 is a wireless communication apparatus for communicating prescribed data in wireless with a back-scattering communication scheme, in which a tag (10) for receiving a carrier wave signal Sf having a frequency of 2.45 GHz and transmitting response signal Sf (D) obtained by modulating the carrier wave signal Sf based on the data and a tag reader (20) for transmitting a carrier wave signal to the tag (10) and receiving and signal-processing a response composite signal that is returned from the tag (10) are provided. This tag reader (20) has a carrier-wave-compensating circuit (30) that compares a phase of the carrier wave signal in transmitting the carrier wave signal and a phase of the carrier wave signal in receiving the carrier wave signal and eliminates a carrier wave composite signal that is not synchronized with the carrier wave signal in transmitting the carrier wave signal based on a comparison result thereof.

    • A reading apparatus includes a control unit and an interface through which the control unit transmits an output request to an electronic tag and receives tag information output from the electronic tag in response to the output request. The control unit is configured to read the tag information received by the reception unit and extract an identifying code from the tag information, store the identifying code in association with a number corresponding to a total number of times tag information including the identifying code has been read by the controller in response to the output request, and output a stored identifying code or information associated with the stored identifying code if the number associated with the stored identifying code meets or exceeds a threshold value.
    • 读取设备包括控制单元和接口,通过该接口,控制单元将输出请求发送到电子标签,并且响应于输出请求接收从电子标签输出的标签信息。 控制单元被配置为读取由接收单元接收到的标签信息并且从标签信息中提取标识码,将标识码与对应于包括标识码的标签信息的总次数已经被读取的次数相关联地存储 由控制器响应于输出请求,并且如果与所存储的识别码相关联的数量达到或超过阈值,则输出存储的识别码或与所存储的识别码相关联的信息。
