DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application 1] The present invention relates to an information storage and display card that records 4N information and displays the recorded information. Mainly, it is r'a for IS% band cards.

[Previous technology] Traditionally, cards that have information recorded on them include so-called magnetic recording cards, in which information is magnetically recorded in stripes, as well as information displayed as barcodes consisting of a combination of bars and spaces. A so-called barcode display card is known.

Magnetic recording cards are devices in which various types of information are recorded in the form of magnetic stripes using a magnetic head, and because the information can be read out sequentially by the magnetic head, they are used in many fields such as credit cards. . In addition, barcode display cards convert information into barcodes and print this barcode on the card itself (often on a piece of paper), and the barcode is optically read by a barcode reader or the like. llF continuation processing.

[Problems to be solved by the invention] The former magnetic recording card has the advantage of being able to change the recorded information to nodes, but on the other hand, there is a risk that the recorded information will be destroyed if it is brought close to a magnetic object. There is a characteristic, ■=+n
Even if the information is destroyed, it is not possible to visually confirm whether the information has actually been destroyed. The drawback was that there were limits.

The latter barcode display car 1ζ has fewer of the drawbacks of magnetic recording cards, but the information recorded is unique to each car 1? If the information is different for each item, for example, a door number, etc., the printed contents will be different in one sheet, so it will be more expensive.''0, Since the information is printed, it is not easy to respond to changes in information. was there.

U (So, it was not suitable for handling variable information.

In this way, since all BR (σ) cards have their advantages and disadvantages, there is a desire for a card that eliminates the disadvantages of both cards.

Here, one object of the present invention is to meet such demands,
The objective is to provide an information record/person display card that eliminates all the drawbacks of conventional cards. In other words, if the recorded information is not destroyed by magnetic interference,
[An object of the present invention is to provide an information storage/display card that can be confirmed to a certain extent by Ll even if one report is destroyed, does not have a short life due to wear and the like, and can also change information in the cylinder.

[Means for resolving the problems in one go] Therefore, in the present invention, a display section is provided on the surface of the card body, and the card body also includes a memory, data from the outside is written to the memory, and data stored in the memory is provided. Features 1 and ν include a control section for displaying a bar code on the display section, and a power source for driving the display section, memory, and control section.

[Operation 1 Data from the outside is stored in the memory, and the data is displayed as a barcode on the display. Therefore, in use, the barcode data displayed on the display section is optically read, and there is no deviation in the decoding process.

Therefore, the data is not destroyed by magnetic interference, and since the data is displayed in a barcode, it is possible to visually confirm whether or not the data has been destroyed. Furthermore, the detection head does not come in direct contact with the data. There is no reduction in service life due to wear, and since data from the outside can be written to the memory, even if the data differs from one sheet to another, it can be easily handled by simply changing the data from the outside. Variable data can also be handled.

C Embodiment 1 Hereinafter, an embodiment of the present invention will be explained based on the drawings.6 FIG. 1 shows a Florafre 1 showing an embodiment of the information storage display card of the present invention, and FIG. 2 is a perspective view thereof.

As shown in these figures, a liquid crystal display 12 as a display section is provided on the front of a thin card body 11. Further, inside the card body 11, data from a memory 13 and an external setting device 21 connected via a connector 14 are stored in the memory 13, and data from the memory 13 is stored via a display driver 15. The liquid crystal display 1
