- An antenna 66 is shared as an antenna for the IC card chip 44 and the display control chip 61. Manufacturing costs can be reduced by sharing the antenna.
- the manufacturing error of the resonance frequency of the existing non-contact type IC card is allowed up to about 5%, so the fluctuation of the resonance frequency when the display module is mounted should be within this range. If this is possible, it is not necessary to modify the IC card chip antenna in addition to the IC card chip.
- the resonance frequency fluctuation when the display module is mounted is determined by the ratio of the load current of the antenna for the display module to the load current of the antenna for the IC card chip according to electromagnetic analysis. Assuming that the resonance frequency of the existing contactless IC card is 13.56 MHz and that the variation is within 5% when the display module is installed, the load current for the display module is the load of the IC card chip antenna. It can be seen that it should be 5.4% or less of the current and 10.8% or less when converted to electric power.

In this case, it is desirable to display an area 79 in which the display module can be pasted on the non-contact type IC card 70 as shown in FIG.
- the overall resonance frequency force when the display module 80 is in close contact with the non-contact type IC card 70 must be 95% or more of the resonance frequency of the non-contact type IC card 70 alone. Is desirable.
- the reader / writer and the non-contact type IC card can execute signal exchange as follows. First, the reader / writer identifies and detects the main R FID chip by polling through the anti-collision procedure, and communicates normally. Next, the reader / writer is polled. The display control chip is detected and data to be displayed is transmitted. The display control chip receives the data to be displayed and displays it on the memory display panel.
- FIG. 9 is a diagram showing a relationship in which the RFID reader / writer corresponding to each procedure and the non-contact type IC card with a display function can communicate with each other.

- the non-contact IC card 220 with display function that supports both procedures has three RFID reader / writers 100, 110 and 120. Can communicate with.
- FIG. 10 is a diagram showing a processing sequence according to each procedure.
- the RFID chip and the display control chip each return a response.
- the RFID reader / writer applies an anti-collision procedure to these multiple responses, selects one partner, in this case, the RFID chip, and authenticates the RFID chip.
- the display control chip is authenticated according to the response of the display control chip. If authentication is successful, display data is written to the display control chip using the device ID of the display control chip obtained at the time of authentication. Display control chip displays display data on display element
- the RFID chip responds to the polling of the RFID reader / writer, and normal communication is performed with the RFID chip after the authentication procedure.
- the R FID reader / writer requests the device ID of the display control chip from the RFID chip.
- the RFID chip holds the device ID of the display control chip and sends it to the RFID reader / writer.
- the RFID reader / writer adds the device ID to the write data and sends it to the display control chip.
- the device ID of the display control chip has a specific relationship between the device ID of the display control chip and the device ID of the corresponding RFID chip. It can also be calculated.
- the display control chip responds to polling, so the processing sequence of the anti-collision procedures is the same. There is no response from the display control chip for a card with an unauthenticated write procedure! Therefore, it is recognized that the card is an unauthenticated write procedure card, and the display data is written according to the unauthenticated write procedure. .
- the non-contact type IC card with display function is compatible with both the RFID reader / writer of the anti-collision procedure and the non-contact type IC card with display function of the non-authentication write procedure. If the RFID reader / writer is compatible with an anti-collision procedure card or both an anti-collision procedure card and an unauthenticated write procedure card, the display control chip responds to the polling. This is the same as the processing sequence of the same anti-collision procedure. If the RFID reader / writer is compatible with a card with an unauthenticated write procedure, the display control chip is not polled, and the process proceeds according to the unauthenticated write procedure.
- the present invention has been described by taking the non-contact type IC card as an example of the information medium, but it is clear that the shape of the information medium of the present invention is not limited to the card. Further, as apparent from the above description, according to the features of the present invention, the IC card chip A display function can be added without modifying the core part of existing information media such as a desktop. Further, according to another feature of the present invention, modification of an antenna of an existing information medium can be unnecessary. Furthermore, according to another feature of the present invention, a display function can be added without modifying the existing information medium itself.
- the display data to be transmitted to the reader / writer power display module is not limited to balance data as a result of processing by the reader / writer, for example, but the data processed on the information medium side is displayed as display data to the display module via the reader / writer. It can also be sent and displayed.
