To provide a label printer that has a communication function of communicating with an IC tag attached to a label, which can easily prepare a label that can be utilized for management.SOLUTION: A label printer 1 reads out a unique ID previously memorized in an area where an RFID tag 50b cannot be written in, from the RFID tag 50b attached to an RFID label 50a being conveyed, through an RFID reader writer 16. Further the label printer 1 prints an image showing the read-out unique ID on a printing surface of the RFID label 50a using a printing engine 51.SELECTED DRAWING: Figure 6

To provide an RFID tag capable of suppressing the number work man-hours for discarding the RFID tag.SOLUTION: The RFID tag is attached to an object and includes a radio tag circuit element arranged on a body. The radio tag circuit element includes a loop antenna part for transmitting and receiving information to and from a reader writer. The body has at least one of a through hole for attaching the RFID tag to the object and penetrating a region surrounded by the loop antenna part in the body and an adhesive part provided in an adjacent part adjacent to the loop antenna part and attaching the RFID tag to the object.SELECTED DRAWING: Figure 3A

To provide an integrated reader / writer that can more reliably execute authentication of a two-dimensional code displayed on a smartphone.SOLUTION: A reader / writer obtained by integrating a non-contact IC reader / writer 40 and a two-dimensional code reader 30 is provided with an illuminance sensor 51 that detects illuminance of a display of the smartphone, and a proximity sensor (distance measuring sensor) 52 that detects approach of an authentication medium. When the proximity sensor detects the approach of the authentication medium and determines that the smartphone is held over the two-dimensional code reader, the integrated reader / writer temporarily stops the detection operation performed by the non-contact IC reader / writer.SELECTED DRAWING: Figure 3

To provide a system capable of stably specifying a position of an RFID tag moving across communication regions of a plurality of reader writers (antennas).SOLUTION: A higher control device (10) for controlling a plurality of reader writers (20) communicating with an RFID tag (30) includes: a communication intensity determination unit (12) for measuring communication intensity between the RFID tag and each of the reader writers; and a switching unit (13) for switching the reader writers communicating with the RFID tag according to the communication intensity during communication of data.SELECTED DRAWING: Figure 1

A communication device for communicating with wireless communication devices is provided that includes a shield device defining a plurality of shield spaces arranged along a transport path transporting a sheet on which a plurality of wireless communication devices are arrayed; and a plurality of reader / writer antennas arranged in each of the plurality of shield spaces. Moreover, the plurality of shield spaces are juxtaposed corresponding to an array pitch between the wireless communication devices on the sheet, a part of the shield device is arranged between the plurality of reader / writer antennas, and the plurality of reader / writer antennas are arranged at a side facing a transport surface of the transport path.

A printer according to an aspect of the present invention is for performing printing on a printing medium having an RFID inlay, and comprises: a platen roller that conveys the printing medium; a printing head that has a heating unit formed of a plurality of heat generators arranged in a linear manner and that performs printing on the printing medium while holding the printing medium between the heating unit and the platen roller; a wireless antenna disposed, at a location on the downstream side of a conveyance path for the printing medium with respect to the heating unit of the printing head, on the printing surface side of the conveyed printing medium; and a reader / writer that communicates with the RFID inlay of the printing medium through the wireless antenna.
