Abstract

(57) [Summary] [Purpose] The purpose is to enhance the anti-counterfeit effect by making it difficult to forge a card. [Structure] In membership card and credit card,
Each card body is provided with a forgery prevention mark composed of a hologram in which different identification information is recorded.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a membership card or a credit card in a membership-based amusement hall, and particularly to a card with an enhanced anti-counterfeiting effect.

[0002]

[Prior art]

 Traditionally, forgery has been made by swapping the photos of a membership card with a face photo in a game hall for illegal use, and forgery has been a problem for cards such as credit cards and prepaid cards. For this reason, various anti-counterfeiting measures such as holograms have been taken for the purpose of preventing the counterfeiting itself.

However, these anti-counterfeit patterns are created by mass production, and the same kind of printed matter and card generally have the same anti-counterfeit pattern. For this reason, if a pattern is once forged by some method, the damage may increase due to mass production.

[0004] Furthermore, a name or a number is entered by embossing or the like for individual judgment of a card, but these patterns can be easily forged.

[0005]

[Problems to be solved by the device]

 The conventional card and printed matter have a problem that they are easily forged.

The present invention has been made in order to solve the above problems, and its purpose is to make it difficult to forge a card and enhance the effect of preventing forgery. Is to provide the code.

[0007]

[Means for Solving the Problems]

 The membership card and the credit card of the present invention are provided with anti-counterfeit marks, which are holograms in which different identification information is recorded, for each card body.

The hologram is a multi-dot hologram formed by forming a plurality of dot-shaped element holograms on the surface of a substrate.

[0009]

[Action]

 The card of the present invention has a forgery prevention mark composed of a hologram in which different identification information is recorded for each card body, so that even if the forgery prevention mark of a particular card is forged, It cannot be used as an anti-counterfeit mark.

As a result, it is possible to make it difficult to forge a card and significantly improve the forgery prevention effect. In addition, by using a forgery prevention mark composed of a hologram, it is possible to stereoscopically display identification information.

[0011]

【Example】

 The present invention comprises a card with anti-counterfeit marks, which are holograms in which different identification information is recorded for each card. One embodiment of the present invention will be described with reference to the plan view of FIG. To do.

The membership card 1 shown in FIG. 1 is provided with a forgery prevention mark 2 composed of a hologram in which identification information is recorded, and this identification information includes, for example, a member number and a face photograph, as well as individual names, fingerprints, etc. This is identifiable information.

The forgery prevention mark 2 is recorded as a multi-dot hologram formed by forming a plurality of dot-shaped element holograms on the surface of the substrate. This multi-dot hologram is similar to the well-known method of recording parallax information of multiplex holograms, but this multiplex hologram records only parallax in the left-right direction, whereas Disparity information is also recorded for the direction. This makes the reproduced light wavelength selective, and reproduces the vertical parallax with white light illumination.

An image pattern forming a hologram is condensed on a hologram surface, and reference light is made incident on the condensing portion from the opposite direction, and an interference fringe pattern with the reference light is formed on the hologram surface as a dot-shaped element hologram. Record. Then, the hologram film is moved little by little in the vertical and horizontal directions for sequential exposure, and a dot-shaped element hologram is exposed over the entire hologram surface.

Further, in reproducing a hologram, light rays from respective points on the hologram surface can be reproduced correctly and a stereoscopic image can be observed. With the hologram as a window, the directions and intensities of all the light rays that pass through the window can be corrected. It records and reproduces, and can reproduce a stereoscopic image without any distortion.

The membership card 1 of the present embodiment is a multi-dot hologram in which different identification information is recorded for each card body, that is, a multi-dot hologram can directly record data from a computer, etc. Different information can be recorded for each 2 and even if the forgery prevention mark 2 of a particular membership card 1 is forged, it can be used as the forgery prevention mark 2 of the other membership card 1 I can't.

Further, by using the anti-counterfeit mark 2 composed of a multi-dot hologram, the identification information can be displayed three-dimensionally, and further, by recording the name and number as the hologram, the A higher anti-counterfeiting effect can be provided.

Further, it becomes possible to realize an automatic system of the forgery prevention mark 2 with one optical system, the laser light can be effectively used, and the exposure time is short, so that it is not affected by external vibration.

[0019]

[Effect of device]

 As described above, according to the present invention, each card body is provided with the anti-counterfeit mark composed of the hologram in which the different identification information is recorded, which makes it difficult to forge the card. This has the effect of enhancing the anti-counterfeiting effect.

Claims (2)

[Scope of utility model registration request] 1. A membership card or a credit card, characterized in that each card body is provided with an anti-counterfeit mark composed of a hologram in which different identification information is recorded. 2. The card according to claim 1, wherein the hologram is a multi-dot hologram in which a plurality of dot-shaped element holograms are formed on a surface of a substrate.
