BACKGROUND OF THE INVENTION
The present invention relates to security improvement means for an auxiliary memory such as a mobile phone or a PC card, or a SIM card used as an ID.
[0002]
[Prior art]
In recent years, with the progress of telecommunications technology and the miniaturization of IC chips, for example, mobile communication terminals such as mobile phones and in-vehicle terminals have rapidly spread.
In a mobile phone, an IC card connector is installed inside the phone, a small IC card storing a registered phone number is attached, and the call charge of the mobile phone is the same as the call charge of the registered phone described above. As a payment system is used.
The aforementioned small IC card is called a SIM (Subscriber Identity Module) card and is widely used in Europe and the like.
Further, when used in a notebook personal computer, it is mounted in a PCMCIA card to enhance security, or is mounted on an IC card reader / writer and used as an authentication card.
[0003]
However, a small IC card represented by the SIM card (hereinafter referred to as a SIM card) occupies most of the area of the front surface with the external terminals of the IC module, and there are few flat portions on the back surface. Therefore, at present, only limited information of card-specific information is printed.
Therefore, if the SIM card carrying the important information of the holder is stolen or is small, it is easy to drop it, and if it is used by a third party, it is proved to be its own at least by appearance There are many cases where impersonation must be tolerated because it is difficult to do.
[0004]
As a measure to prevent the above-mentioned misuse, the unique information of the legitimate holder is printed on the SIM card to give a psychological resistance to the third party to be exploited. As a second step, it is possible to confirm the unique information recorded on the IC card.
[0005]

DETAILED DESCRIPTION OF THE INVENTION
The IC card of the present invention will be described below with reference to the drawings.
[0016]
1 is a diagram in which the cardholder's unique information is printed on the back side of the SIM card, FIG. 2 is a diagram in which the cardholder's unique information is printed on the front side of the SIM card, and FIG. when provided to holder held by the frame card information printed on the SIM card is a diagram for explaining a state in which is also printed on the frame card, FIG. 4, the cross section of the S IM card FIGS. 5 and 6 are diagrams for explaining a state in which image information of a valid cardholder recorded on the SIM card is displayed on the display unit of the mobile phone when the SIM card is inserted into the mobile phone. These are figures for demonstrating the manufacturing method of the card | curd by a lamination | stacking system.
[0017]
In the embodiment of FIG. 1, the back side 5 on which the IC module of the IC card (SIM card) 1 is mounted has a gap between the recess formed on the card base and the mounted IC module, as will be described later. When the recess is formed, heat is generated and the plastic expands, so that some deformation remains.
For this reason, uniform printing cannot be performed in a printing mode in which information is displayed by bringing a thermal head such as a thermal transfer system or a sublimation transfer system into contact with a printing surface. Therefore, as described in the previous section “Prior art”, the back 5 portion of the module mounting portion is determined as a non-printing portion. However, since there is no other space except for this part, information has been barely displayed by methods such as reducing the characters.
In FIG. 1, the character information 4 is printed on the back surface 5 of the module mounting portion. However, according to the present invention, since the sublimation retransfer method is used, the thermal head does not directly contact the printing portion and is printed once on the heat resistant film. Since the reverse image is re-transferred to the card surface (transferred with a rough surface-compatible material such as heat-resistant rubber at the time of re-transfer), an image is clearly formed on the card surface.
[0018]
The embodiment of FIG. 2 departs from the purpose of absorbing and printing the irregularities of the present invention in a state where the card holder's unique information is printed on the external device connection terminal surface (hereinafter referred to as the external terminal surface) of the SIM card. However, since the external terminal part has some irregularities compared to other parts, if image formation is repeated on this part with a thermal head, scratches occur at positions corresponding to the external terminal positions of the IC module of the head. Or when the image is printed on the other surface due to wear of the head, a phenomenon occurs in which the portion is unclearly printed.
However, if printing is performed by the sublimation type retransfer method, it can be performed without any problem even on the external terminal surface, which is also effective for the external terminal surface of the SIM card.
[0019]
In the embodiment of FIG. 3, when the SIM card 1 is held on the frame card 10 and provided to the card holder, the provided card holder uses the SIM card 1 by removing it from the frame card 10.
Here, the reason for providing the SIM card by holding it in the frame card will be described.
The SIM card is a small IC card of approximately 25 × 15 × 0.76 mm.
In contrast to the SIM card, the frame card has a standard card size of 85.6 × 53.98 × 0.76 mm, which is the same as the credit card defined in ISO 7810, which boasts an overwhelming number.
Many card peripheral devices are manufactured in accordance with the frame card size, and the above-described sublimation type retransfer printing machine (printer) is the same.
Peripheral devices manufactured in other frame card sizes include card embossers, IC / magnetic encoders, signature panel stampers, IC module mounting machines, card inserters, thermal type, sublimation transfer type, laser type facial photo printers (printers) ), Other magnetic card peripheral devices for general users, IC card peripheral devices, and the like.
[0020]
As shown in FIG. 3, by holding the SIM card on the frame card and providing it to the card holder, it is easy to handle the process before shipment of the SIM card, and the frame card has precautions regarding the handling of the SIM card. By printing it, the usability of the SIM card can be improved. By printing the owner's unique information, it can also be used as a proof means when the SIM card is accidentally lost.
[0021]
With reference to the cross section of the SIM card in FIG. 4, the necessity of printing by the sublimation retransfer method or the ink jet method when displaying images or characters directly behind the IC module, which is a feature of the present invention, will be described.
[0022]
The card base is printed on a thermoplastic plastic sheet and laminated by heat and pressure (described in detail in FIG. 6). As shown in FIG. 4, a transparent sheet 101, a milky white sheet (core sheet) 105, a transparent sheet A laminate of sheets 101 is formed.
A two-stage recess is formed on the above-described laminated sheet using a router, and the shallow recess (the hatched portion indicated by 23) is formed so that the circuit board 23 of the IC module is fitted into the deep recess 21. Is formed so as to accommodate the sealing resin portion 22 of the IC chip.
As can be seen from FIG. 4, the deep recess 21 is set to have a large depth and width so as to allow an error in the size of the sealing resin portion and the mounting position of the IC module. End up.
Further, as described above, since the card base is a thermoplastic resin, after forming the deep concave portion, the transparent sheet portion on the back side of the concave portion is distorted as shown in FIG. As a result, even if sublimation transfer printing or thermal transfer printing is directly performed on a portion wavy due to such distortion with a thermal head, ink is not uniformly transferred.
Therefore, conventionally, at least an area corresponding to the back of the IC module is set to avoid printing.
[0023]
However, according to the sublimation type retransfer system, the image or character to be transferred is once printed with a sublimation transfer ink on a material that absorbs irregularities, such as heat-resistant rubber, and the rubber is used as a card substrate. It is possible to form a clear image or character even on an uneven portion by pressing and retransferring.
In addition to the retransfer method, for example, a heat-resistant thin film 304 such as polyimide is coated with a protective layer / release agent 303 in advance, and then a reverse image is formed with sublimation transfer ink 302. Printing is performed on a card base on which the image receiving layer 301 is formed, and pressed with a soft material such as rubber that has been molded to a required size.
The transferred image or character is printed on the card substrate as a correctly oriented image or character.
[0024]
The re-transfer method is preferable when forming an image with a thermal head as described above on an uneven surface. However, even if ink is directly sprayed on the uneven surface by an ink jet method, the image is accurate with high quality. Can be formed.
[0025]
FIG. 5 shows a state in which the SIM card 1 is inserted into the card storage unit entrance 71 of the mobile phone 7 and the face image of the holder recorded on the SIM card is displayed on the display unit 72 of the mobile phone.
In addition to personal information such as the face image of the owner, the SIM card records the number of the home phone, so that the mobile phone usage fee can be withdrawn from the home phone bill automatic payment account, You can give instructions to home appliances and check the state of your home room. A SIM card can be used as the personal authentication means at that time.
Normally, when the mobile phone is carried, the power is turned on, and the display unit displays the date, time, and the like.
When a new function is called, first, a face image stored in the SIM card is displayed, and a setting is made so that the user is informed visually.
Although it can be programmed to input a password and confirm the identity each time the power is turned on, it is cumbersome, and normally the password is input only when the SIM card is mounted on the mobile phone.
In this way, even if an unauthorized user misappropriates the owner's personal identification number and impersonates the owner, the face projected on the display unit of the mobile phone is displayed by another person. There is a risk that can be seen in the above, and this creates a great pressure, and an effect of restraining unauthorized use occurs.
[0026]
Hereinafter, a method for producing a laminated card will be described with reference to FIG.
As shown in the milk white sheet 102 for normal printing, printing is performed with multiple impositions, and the frame cards 10 are regularly arranged in rows and columns.
The front and back designs are printed on each of the front and back milky sheets 102 which are front and back printed sheets.
Different printing methods are used depending on the design, but as described above, fine lines and photographs are often printed by the offset printing method.
The printing ink used is UV (ultraviolet) curable ink, rarely oxidation polymerization type ink, UV ink is irradiated with ultraviolet rays and dried instantaneously. Oxidation polymerization type ink is exposed to air in the air for a certain period of time. Leave to dry.
Also, heavy and deep designs are printed by screen printing.
Since the ink for screen printing usually dissolves the pigment and the resin with a solvent, the solvent is volatilized and dried.
[0027]
When the printing ink is dried, the milky white sheet 103 as a core is sandwiched between the front and back milky sheets 102, and the transparent sheet 101 is stacked on the front and back printing ink surfaces.
When a magnetic recording part is required, a magnetic stripe is previously transferred onto the surface of the transparent sheet.
Lamination is usually performed by heat and pressure. When using adhesive, heat-reactive type adhesive should be applied to both sides of the printed sheet, or both sides of the milky white (core) sheet and the transparent sheet. Keep it coated.
The conditions for lamination are when the material is vinyl chloride, the temperature is 110 to 160 degrees Celsius, the pressure is 2 to 3 MPa, and the heating and cooling time is 40 to 60 minutes.
The multi-sided laminated sheet that has finished the laminating process is subjected to a die-cutting process to form one card.
[0028]
In order to make an IC card, first, a recess for mounting an IC module is formed on a credit card-sized frame card completed through the steps described above.
As described with reference to FIG. 4, the recess includes a shallow recess for fixing the IC module and a deep recess for storing the sealing resin portion of the IC chip. First, a large shallow recess is formed. A small and deep recess is formed.
[0029]
When the recess is formed, in order to manufacture the SIM card 1, the router forms grooves 12 penetrating the front and back of the frame card in accordance with the outer shape of the SIM card as shown in FIG. At that time, the bridge 11 is left on the upper and lower sides or the left and right sides of the SIM card.
Next, the IC module is bonded and fixed by applying an adhesive to the shallow concave portion.
The order of the groove formation and the IC module bonding process may be interchanged.
[0030]
The resulting was framed SIM card, together with the data required for the IC chip is recorded visual data is printed are stacked on the sublimation type retransfer device. Visual data may be printed first, and optical reading information such as a barcode printed together may be read, and related data may be written to the IC chip using this as a search key.
[0031]
The completed SIM card with a frame is enclosed and sealed in an envelope together with promotional materials and other print data forms by a card inserter (a device for fixing the card to a sending board on which related information is printed) and mailed.
[0032]
【Effect of the invention】
(1) In the case of a SIM card, a limited and small space can be fully used as the visual information display unit.
(2) The owner can be visually confirmed without reading the IC recording part of the SIM card.
(3) By storing face image information in the IC chip and displaying it as necessary, it is possible to give an effect of suppressing unauthorized use to unauthorized users.
(4) By printing the same face image on the frame card as on the SIM card, it is easy to identify the person when handing it over to the person in case of loss.
