BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is, for example, for cash cards, credit cards, prepaid cards, and other various cards, whether the card itself is true or false, or the authenticity of the card data recorded on the above various cards. In order to make a false decision, the ID (indentificatio
n, authentication) The present invention relates to an ID information recording medium to which information is added and an ID information recording / reading method thereof.

[0002]

2. Description of the Related Art Conventionally, as an ID information means for discriminating the authenticity of a card, a method of specially processing the card such as a means of burying a phenol resin in the card at the time of manufacturing the card, or a magnetic ink on the card There has been a method of manufacturing a card by printing ID information with a special ink.

In the case of manufacturing a card by adding ID information by the means as described above, there is a problem that the card price becomes very high if the number of manufactured cards having the same ID information is small. Since there are a limited number of types of cards, there is a problem in manufacturing many types of cards.

[0004]

DISCLOSURE OF THE INVENTION The present invention is such that the ID information added at the time of manufacturing a recording medium such as a card can be changed after the recording medium is manufactured.
It is an object of the present invention to provide an ID information recording medium that can issue a recording medium provided with various types of inexpensive ID information and a method for recording and reading the ID information.

[0005]

According to the present invention, there is provided a thermosensitive printing layer formed on a surface of a base material, and a fluorescent material is printed on the thermosensitive printing layer to form an ID information recording portion. The ID information is recorded in the information recording section by thermal printing, and the ID is recorded.
At the time of reading information, the light amount necessary for the fluorescent material of the ID information recording section to emit light is applied to the ID information recording section, and the light from the ID information recording section is detected to detect the presence / absence of the fluorescent material and the fluorescent information. The ID information is read by determining the information regarding the presence or absence of thermal printing in the material portion.

[0006]

The fluorescent material in the ID information recording portion of the ID information recording medium is printed at the time of manufacturing the recording medium, and this printing is also performed by various kinds of printing such as flat printing from the fluorescent material itself. it can. On the other hand, in the thermal printing of the ID information recording unit, for example, when this recording medium is used as a card, it is printed when the card is issued. Therefore, as the ID information, a large number of types can be created by combining the presence / absence of printing with a fluorescent material and the presence / absence of thermal printing. Furthermore, the printing of the fluorescent material is a bar code, and the fluorescent information is printed during the thermal printing. If the barcode of the material is crushed, the ID information can be changed when the card in the above-mentioned example is issued, and the types of recording media having the ID information can be increased.

[0007]

As a result of the above, according to the present invention, since the ID information is obtained by organically combining the two means of printing the fluorescent material and the thermal printing, the recording medium having more ID information than before. Therefore, various types of recording media can be issued.

Further, since the ID information can be added and changed when the recording medium is issued, even if one kind of ID information is printed by the fluorescent material when the recording medium is manufactured, it is changed to another ID information by thermal printing when the recording medium is issued. As a result, a large number of types of recording media can be issued, and as a result, the manufacturing cost of the recording medium can be reduced by manufacturing one type or a small number of types in large quantities.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail below with reference to the drawings. The drawings show an ID information recording medium and its recording / reading method. In FIGS. 1, 2 and 3, a card 10 shown as an example of the ID information recording medium is provided with a well-known heat-sensitive agent on the entire one side surface of a base material 11. The white thermosensitive printing layer 12 is formed by coating, and the white fluorescent material 14 is printed on the set ID information recording portion 13 to manufacture the card 10. When both the thermal printing layer 12 and the fluorescent material 14 are formed in the same white color, the printing of the fluorescent material 14 can be hidden and the ID function can be improved.

The card 10 manufactured as described above is
