  The display 5 of the electronic device 100 with a display function can be installed at any position on the front surface 1c, the upper surface 1b, and the side surface 1a of the outer shell 1 of the bag article provided with the wireless tag, or the display 5 is provided at the handle of the bag article. Can also be installed.

  When the display 5 is installed on the handle, the display 5 is separated from the electronic device 100 with a display function, and the power supply wiring and signal wiring of the display 5 are connected to the electrical terminals of the electronic device 100 with a display function. It is desirable.

  The display 5 is preferably composed of a non-volatile display device, or it is desirable to use a display 5 such as electronic paper that consumes less power during a period of holding an image. Accordingly, the display content can be held even when the supply of power is stopped.

  For example, the display 5 is configured by an electronic paper such as an electrophoretic method, a ferroelectric liquid crystal, a cholesteric liquid crystal, or an electrochromic liquid crystal. On the other hand, the display 5 may be displayed only while power is supplied from the baggage detection system 300, and a liquid crystal other than electronic paper, an organic EL, or the like can be used for the display 5.

  The image to be displayed on the display 5 is displayed so that it can be read using conventional infrastructure products and devices such as a hand scanner, bar code scanner, or automatic baggage scanner in the same manner as a paper bag tag. That is, a bar code or a QR code (registered trademark) is displayed, and a plain text, a reference number, or the like is displayed.

  As a result, even in an airport where there is no facility for wirelessly reading data of the electronic device 100 with a display function, it can be handled in the same manner as a bag article attached with a paper bag tag using conventional equipment. The attached electronic device 100 can be widely used in the same manner as a paper bag tag.

  In addition, since the power necessary for switching the display of the display 5 made of electronic paper or the like can be supplied from an external device when the display needs to be switched, only a small amount of power is stored in the built-in power supply 8. Thus, there is an effect that an effective display on the display 5 can be maintained for a long time.

(Control element)
A control element 7 composed of a control microcomputer or the like controls the operation of the entire electronic device 100 with a display function. The control element 7 exchanges data with the electronic circuit 10 having a wireless communication function via the wired interface circuit 12.

  The control element 7 controls the display driver means 6 using the data stored in the storage unit 14 of the electronic circuit 10 having a wireless communication function, and displays it on the display 5. That is, the display 5 displays various information such as identification information of the electronic device 100 with a display function, and information on the itinerary, trip, and airport premises information stored in the electronic device 100 with a display function.

  The control element 7 designates or confirms the tag ID (TID or UID) stored in the storage unit 14 of the electronic circuit 10 having the wireless communication function, and then exchanges data with the electronic circuit 10 having the wireless communication function. Or, other operations can be performed.

  The electronic device 100 with a display function may be configured by incorporating the display driver means 6 in the control element 7. Furthermore, the functions from the control element 7 to the electronic circuit 10 having a wireless communication function may be configured by integrating functions into one integrated circuit chip.

  Moreover, it is also possible to incorporate a sensor element into the electronic device 100 with a display function so as to have a sensing function of a specific physical quantity.
