Description

DETAILED DESCRIPTION OF THE INVENTION Purpose of the invention: (Industrial field of application) The present invention relates to a card on which a gradation image such as a facial photograph is printed with colorless fluorescent ink on the card surface.

(Prior art) Cards have become popular with the development of the information industry,
Bank cards such as cash cards use the PIN to verify the identity, and credit cards use the signature on the back of the card to verify the identity.
When collating with a personal identification number, the number of combinations of numbers and alphabets is limited, it is relatively easy to decipher the personal identification number, and there is a problem in terms of security. Also,
When checking the signature, the signature is pre-signed on the back of the card, and there is a risk of copying the signature by looking at it and it is difficult to confirm whether the signature was made by the same person. There is.

(Problems to be solved by the device) For this reason, in ID cards, etc., the face photograph of the person is printed in black and white or color and used for verification, but the card has a space for forming or printing the face photograph. Must be taken on the face. There is also a problem that the face photograph and other print information must be designed so as not to overlap with each other.

This invention was made under the circumstances as described above,
The purpose of this idea is that there are no restrictions on card design,
Moreover, it is to provide a card with extremely high security.

Configuration of Device: (Means for Solving the Problem) This device relates to a card such as an ID card or a bank card. The purpose of the device is to use a colorless fluorescent ink on the card surface for gradation of a facial photograph or the like. Dot) achieved by printing the image.

(Function) In the card of the present invention, a face photograph or the like is printed as a gradation (halftone dot) image with colorless fluorescent ink on the surface, so it does not mean that the face photograph or the like is normally printed on the card. It is not visible and there is no problem in terms of aesthetics. Then, when the card is irradiated with ultraviolet light such as black light, only the facial photograph of colorless fluorescent ink emits light, and you can check the image that is the identification element for identifying the card holder. Can be done.

(Embodiment) FIG. 1 shows an embodiment of the present invention, in which a magnetic stripe 11 for magnetic recording is formed on the surface of a rectangular card 10.
Is provided, and various printing information such as name, expiration date, etc. 12
Along with this, a photograph 13 of the person's face is printed in colorless fluorescent ink. Colorless Fluorescent inks have Z _n S (C _u system) or the like, formation of the fluorescent ink printed layer letterpress printing, other various printing methods such as offset printing, or in a manner by thermal transfer and the like.

FIG. 2 is a cross-sectional structure taken along the line XX of FIG. 1, in which a printing (design) layer 15 on which various printing information 12 is printed is provided on a card substrate 14 such as PET or PVC, and on top of that, Further, an oversheet 16 is layered. A magnetic stripe 11 is provided on the surface of the oversheet 16, and a facial photograph 13 is printed with colorless fluorescent ink, and a colorless and transparent protective layer 17 for protecting the facial photograph 13 is provided above the facial photograph 13. May be layered.

In such a structure, since the visible light is irradiated to the card 10 in a normal state, the face photograph 13 with the colorless fluorescent ink is used.
Is invisible to the eye. Therefore, various print information
Only 12 can be seen. However, as shown in Fig. 3, the black light 20 installed in the sales floor, etc.
When the card 10 is illuminated with 21, the face photograph 13 emits light and can be seen with the eyes, whereby the person can be collated. In this case, the various print information 12 cannot be read.

FIG. 4 shows another card example. In this example, a facial photograph 15 is printed on a printing (design) layer 15, and an oversheet 16 is layered on it. Is provided with a magnetic stripe 11.

In the above, the face photo is printed on the card surface,
It may be a whole body image or the like.

Advantageous effect of the invention As described above, according to the card of this invention, it becomes an identification element for identifying the cardholder by the colorless fluorescent ink at any position without changing the design of the card currently issued. Images such as facial photographs can be inserted, which also prevents counterfeit cards. In addition, regarding theft card, the current security has reported the theft, and CA
It is difficult to prevent crime until it can be judged by T (Credit Authoriziation Terminal), but this point makes the card of the present invention extremely effective.
