JPH11110512A - Noble metal authentic/false confirming card and noble metal authentic/false confirming method using the same - Google Patents

Abstract

PROBLEM TO BE SOLVED: To improve reliability and to provide a stable cash card by embedding a microcomputer, to which information for authentic/false confirmation is inputted separate from a noble metal into a plastic card. SOLUTION: Near one edge part of a plastic card 1 having the same size as a card to be used for ordinary credit, kinegram gold 2 of 10 g is embedded in three to four layers through plastics. Further, at the edge part on the opposite side of the kinegram gold 2, a microcomputer 3 is embedded at an ISO specified position similar to the kinegram gold 2, so that the microcomputer cannot be detached from the plastic card 1, as long as the plastic card 1 itself is not destroyed. Thus, reliability is improved, and a stable cash card can be provided.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plastic card to which a thin plate of a noble metal such as gold or platinum which can be exchanged for money is attached.

[0002]

2. Description of the Related Art As a sheet of gold whose cash is guaranteed by a specific institution, for example, Lanlis & Gyr Communicatio in Switzerland
Some are referred to as kinegrams by ns. The thin gold plate is a thin rectangular plate of pure gold of 99.99% or more, the surface area of which is adjusted according to the weight of gold. An embossed pattern is applied, and when it is illuminated with white light, it has a unique color pattern, and this color pattern has a different color tone and pattern depending on how it is illuminated. Makes forgery impossible.

In recent years, this precious metal plate has been incorporated into a normal card with a guarantee number for each price (weight).
This is a useful means as a protection means of the cash guarantee. This usefulness has been focused on the use of pachinko machines, bicycle races, and racetracks as simple cashing means, and a means for guaranteeing the value of precious metal platelets embedded in cards has been desired. Was.

SUMMARY OF THE INVENTION An object of the present invention is to find a means for easily and surely confirming the authenticity of a noble metal plate in such a plastic card in which a cashable noble metal plate is embedded. It is in.

[0005]

SUMMARY OF THE INVENTION The present invention provides a noble metal authentication card for checking the authenticity of an embedded noble metal,
A microcomputer in which information for verifying authenticity is input separately from the noble metal is embedded.

This card can verify the authenticity by extracting only the information of the embedded noble metal from the various information input to the microcomputer embedded in the plastics card. The quality assurance information contained in the board may be compared with the information input to the microcomputer, so that secondary and tertiary authenticity checking means can be used.

[0007] The plastics card is inserted into an authentication device, and the authentication device extracts a specific code or signal from the authentication device provided on the precious metal plate. By verifying the signal against the signal from the microcomputer attached to the plastics card, the authenticity of the noble metal plate embedded can be surely confirmed.

BEST MODE FOR CARRYING OUT THE INVENTION As an example of the present invention, an embodiment of the present invention will be described using a card in which the above-mentioned kinegram gold is embedded as a thin sheet made of pure gold whose cash is guaranteed.

FIG. 1 is a plan view of the card, and FIG.
2 shows a cross section taken along line AA of FIG. In the figure, reference numeral 1 denotes a plastic card having the same size as a card used for a normal credit card. Near one end of the card, 10 grams of kinegram gold 2 is embedded with three to four layers of plastics. Reference numeral 3 denotes a microcomputer, which is embedded at the end opposite to the kinegram gold 2 at the ISO defined position in the same manner as the kinegram gold 2, and is removed from the card unless the card itself is destroyed. I am not able to do it. And on the surface of the card 1,
Kinene gold quality and other guarantees are indicated.

[0010] A fine embossed line pattern is drawn on the surface of the kinegram gold 2 itself, and when light of a specific wavelength is irradiated at a specific angle, reflected light having a specific intensity and color tone is converted to a specific light. Appears at the angle of reflection, which assures the purity of the indicated gold itself.

Further, the microcomputer 3 has inputted quality assurance information of the kinegram gold 2 together with a lot of management information, and these information can be electrically read.

The authenticity of this card is determined by inserting it into a predetermined card reader, for example, in the following procedure.

The card 1 is inserted into an authenticity checking device having a built-in kinegram information detecting mechanism. Here, the reflected light of the kinegram gold 2 is analyzed and its code information is recognized as, for example, an identification code of K1234B6Z, and this is compared with previously input authenticity information to confirm that it is authentic. Confirm. Further, K1234B6Z is extracted as the identification information input to the microcomputer 3, the matching with the kinegram gold 2 is confirmed, and the confirmation of the card owner and other information is completed. In this way, the authenticity of the kinegram gold 2 and the history information of the card owner and other information are confirmed. In this way, the reliability of the card itself can be maintained, and the function as a cash guarantee card can be maintained.

Note that this confirmation procedure is performed by changing the program input to the microcomputer 3 according to the card usage.

[0015]

According to the present invention, the reliability of a plastic card in which a noble metal plate is embedded can be improved, and a stable cash card can be obtained.
