[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method in which a precious metal piece such as gold, silver or platinum is sealed in a card, the precious metal piece can be visually checked, and the value information of the precious metal piece and information unique to the card can be obtained from the card. The present invention relates to a readable card containing a noble metal and a method for manufacturing the card.

[0002]

2. Description of the Related Art Conventionally, as disclosed in Japanese Unexamined Utility Model Publication No. 4-81772 "Card" and Japanese Unexamined Utility Model Application Publication No. 4-5930 "Noble Metal Enclosed Card", noble metal pieces such as gold, silver, platinum, etc. There is a card enclosing jewelry, which is used for trading small amounts of precious metals and as an equivalent exchange with prizes and merchandise as a substitute having a specific value. A plurality of types of cards are used depending on the type, shape, and weight of the precious metal piece according to the amount of money. Also,
Solid printing to prevent fraud such as removing and replacing precious metal pieces etc. in these cards and facilitating the detection of fraud, decorative printing of pictures, patterns, ground pattern, etc. It has been disclosed. Furthermore, the card enclosing the noble metal piece and the like is provided with an information recording section composed of a mechanically readable magnetic stripe or barcode, and the information in this information recording section is read out to perform mechanical processing when exchanging or verifying the card. A possible configuration is disclosed.

[0003] As a method for manufacturing these cards, for example, in Japanese Patent Application Laid-Open No. 4-94994, "a method for manufacturing a noble metal-enclosed card", a precious metal is embedded in a center core portion of a base material and a transparent or translucent sheet is coated on both sides. Then, a manufacturing method is disclosed, in which the components are integrated by a heating press and then punched into a card size. In addition, actual opening Hei 04-35
No. 563, "Package Card", in order to obtain a card having the same outer dimensions without being affected by the difference in the thickness of the noble metal to be enclosed, a noble metal enclosure having a multilayered center core is provided and integrated by hot pressing. After that, a manufacturing method of punching out to a card size has been proposed.

[Problems to be solved by the invention]

[0004] By the way, a card in which these precious metal pieces are enclosed may use a plurality of cards according to the transaction amount or the exchange amount. Further, since a plurality of types of cards are combined, the management of the total transaction amount is performed. To calculate the number of cards, sort them by card type and count the number of cards, or check the card type and the number of cards from the side of the card with the cards overlapped There is a problem that there are many. Therefore, if the number of cards is large or the number of types is large, there is a risk that the counting of the number of members may be incorrect, and the counting of the number of cards may be distracted and the user may not have enough time to check whether the cards are fraudulent. Such,
In handling such a card, it has been desired that counting confirmation be performed reliably and promptly.

If the card enclosing the noble metal piece is too thin, there is a risk that counting errors may occur in the inspection of the number of cards. However, there is a concern that the physical strength, such as bending and twisting of the card, may be reduced.Thus, thinning the card to make it easier to handle is not very desirable. It is. For this reason, the thickness of these cards is desired to be about 1.5 mm to 5 mm. However, if the card is pulled out to a thickness exceeding 1.5 mm, cracks and distortion of the card base material near the edge will occur. Etc. occur,
There is a problem that a high quality card cannot be obtained.
