Abstract

PURPOSE:To ensure that individual data can be recorded into an IC card which is produced to have a common function and that the IC card can be laminated, by imparting minute ruggedness on one side of an IC card to facilitate recording of the individual data. CONSTITUTION:An IC module 2 is fitted in position, and an overlay 4 and core sheets 5, 6, 7 are laminated with each other. To impart minute ruggedness to an individual data recording side of a card to be produced, a polyester film having a minutely rugged surface is superposed on the outer surface 7a of the core sheet 7, and the entire assembly comprising the four layers is clamped and pressed between mirror plates to achieve integral lamination. Thereafter, the polyester film is released from the surface 7a to obtain an IC card having the minutely rugged surface 7a. The individual data is recorded on the rugged surface 7a, and a transparent overlay 8 is placed thereon, followed by lamination.

was manufacturing.

[Problem that the invention seeks to solve]

The structure and manufacturing method of conventional IC cards are as described above, so they are suitable for mass production of single designs or cards with the same design. In the case of IC cards (A77-Cards) that are made using printing and printing power, apart from the common design, different individual information must be recorded on each IC card.

There was a problem with poor productivity.

In addition, since the production of 10 cards and the recording of individual information N on the IC card are done at the same time, 1 of the cards is 0! ! There have been problems in that troubles may occur with a particular card during the production process, or that the issuer of the card cannot easily record individual information on the card.

The present invention has been designed to solve the above-mentioned problems, and after creating an IC card with common functions,
A highly reliable and difficult-to-counterfeit IC that allows individual information to be easily recorded on this E-Card by the issuer of the C-card.
The purpose of this paper is to provide a card and to present a manufacturing method thereof.

[Means for solving problems]

The IC card according to the present invention has an IC module mounted inside, and at least one surface of the card is finished with fine irregularities, and the irregular surface is covered with a transparent sheet and integrated. be.

The method for producing a 10 card according to the present invention includes superimposing a film with a finely uneven surface on at least one side of an IC card, and integrally molding the 10 card by heating and pressing while holding both sides of the 10 card between mirror plates. Thereafter, the film was peeled off to reveal the finely uneven surface, individual information was recorded on the uneven surface, and then it was malized using a transparent sheet.

[Effect]

In the process 0 card and its manufacturing method in this invention, I
Individual information is recorded on the finely uneven surface of the C card.
After card manufacturers created a common card that functions as an IC card, M-
It becomes possible for a card issuer to record individual information on the common card having the finely uneven surface, protect it with an overlay, and integrate it.

[First Example] An example of the present invention will be described below with reference to FIGS. 1(2) to 8. FIG. 1 shows a factory card according to an embodiment of the present invention, and FIG. 1a is a front view thereof, and b is a II card.
! In the figure, 1 is an IC card, and the sheet material is made of 84 sheets.
For example, it has a seed layer structure of opaque core sheets 5, 6 and 7 made of hard vinyl chloride resin, and the IC module 2 is embedded in the through hole 4 inside thereof. The outer surface 7a of the core sheet 7 is finished with fine irregularities, and a common design and individual information specific to the card, such as a personal name and date of birth, are recorded on that surface. Note that a common design is also printed on the surface of the core sheet 5. The outer surface of the core sheet 5.7 is each covered with a transparent overlay 4.
．． 8, forming the surface layer of the IC card 1 (13). Also, a magnetic stripe 3 is added to the back side of the IC card 1 at the same level as the front side of the card.

The work 0 card with the above configuration is created as shown in F below, for example. First, prepare a sheet 5.6.7 made of hard vinyl chloride resin constituting the IC card 1 and of a size that allows a large number of 0 cards to be arranged. Then, a common through hole 21 is provided in the overlay 4 and the core seam 84 of 5.6 so that the IC module 2 can be fitted therein, and the module 2 is installed in this through hole.
The core sheet 7 is aligned and stacked on the eight layers (overlay 4 and core sheet 5.6). In addition, at this time T
A common design is printed on the outer surface of the core sheet 5, and the outer surface of the core sheet 7 (the side that becomes the front surface of the card after card molding) is also printed with, for example, the issue note name, certification card name, background pattern, etc. A common design as a card is printed on it.

Then, as described above, the IO module 2 is attached to the inner IMs, and the overlay 4 and core sheet 5, 6, and 7 are laminated and integrally molded as shown in F. T
That is, after a polyester film (not shown) having a finely uneven surface is overlaid on the outer surface 7a of the core sheet 7 to form fine unevenness for recording individual information (personal information) of the card. , sandwiching the entire four layers (overlay 4, core sheet 5, 6, 7) between mirror plates (not shown),
Apply force and pressure to form a single piece of wood.

After molding, the polyester film is peeled off from the surface 7a of the core sheet 7 and punched into a predetermined card size. In this way, an IC card with fine irregularities ff1lI7& on which individual information can be recorded as shown in FIG. 2 is obtained.

Next, in order to issue an IC card as a 77-card, please refer to the second □□□.
aI! ! Personal information such as name 1 issue date, date of birth, etc. is recorded on the I convex surface 7a, and by overlaying and laminating the transparent overlay 8 prepared as shown in FIG. An IC card (card) 1 with personal information recorded thereon is obtained.

It is also possible to add a personal photo record lO under the overlay 8.

In the above process, it is of course possible to record individual information by peeling off the polyester film after punching out the card into a predetermined size.

In the above example, a polyester film was overlaid and molded on the surface where individual information of the IC card is recorded, and then peeled off after molding. However, if the recording surface is plain, etc., the polyester film is not overlaid, and 10 cards are held in a T6 mirror. Even if the face plate is made of a metal plate having fine irregularities and is heated and pressure-molded, an IC card having a finely irregular surface on which one piece of individual information is recorded can be obtained.

Also, to make it easier to record individual information.

It is also possible to thermally transfer a porous sign panel to the area where the recording T is to be recorded.

In summary, for IC cards (such as Yori cards) that record different information on individual cards, we first manufacture IC cards with a common design printed on them, and then form microscopic uneven surfaces on the surface of the cards. This makes it easier to record information, and allows even card issuers to record information in duplicate. Also, when laminating the overlay 8 to the core sheet 7,
Since the surface 7a of the core sheet 7 is uneven, it is easy for air to escape during subsequent operations, and an IC card with a clean finished surface can be obtained.

〔Effect of the invention〕

As described above, according to the IC card according to the present invention, at least one side of the card is formed with fine irregularities, making it easier to record individual information required when creating cards, etc. After creating an IC card with 8a functionality, a card issuer can record individual information on the IC card, and then cover it with simple lamination to issue a highly reliable IC card. It has the effect of

Furthermore, according to the method of using the IC card according to the present invention, (1
, 9 A T6 EO card with a fine gate and convex surface that records different information can be created using a simple process of preparing a film with a concave and convex surface compared to the conventional process, and is an IC with a clean finished surface. It has an effect that allows you to obtain cards.
