Description

  The present invention relates to an IC card issuance processing method, an IC card IC module, and an IC card. More specifically, the present invention relates to a method of performing IC card issuance processing, particularly electronic issuance processing, at the COT stage before mounting an IC module on a card, and mounting the IC module on an IC card substrate after the issuance processing.

  The IC card is classified into a contact IC card, a non-contact IC card, and a contact / non-contact IC card (2 way, or generally a combination card, dual card) in terms of functional form. Also, if classified according to their use, they are generally stored in personal wallets, such as credit cards and cash cards, and can be taken out and inserted into read / write devices only when necessary, mobile phones, satellite broadcasting There are various uses and usage methods, such as those that are used in the state of being installed in an ETC in-vehicle device or the like. Each environment is different.

  By the way, the IC card is, for example, a credit card. Ultimately, as personal information, membership number, personal name, gender, personal identification number, usage amount restriction information, types of applications that can be used, etc. Different information for each individual is written in the IC chip, part of the information is recorded as magnetic data or embossed data, and a face photo is printed on the card surface. It will be ready for use.

In general, it is the primary issue that loads common application programs, the storage of common data other than personal information, the creation of files, etc., common to a lot of cards, individual information that is different for each individual, Issuing processing for performing individual customization of an application is called secondary issuance.
Conventionally, in the state of a tape-like IC module (hereinafter referred to as “COT” (Chip On Tape)), there is a case where primary information such as pre-filling common information or loading a common application is performed. This is not done until the next issue, and the latter is basically done after the completion of the IC card.

In the case of the conventional IC card issuance processing, especially in the case of the contact IC card and the contact / non-contact IC card described above, the IC module is mounted on the IC card substrate, and the IC card is almost completed. It is usual to perform issuance processing by writing data necessary for use as a card.
Originally, this issue processing procedure is unlikely to cause a difference between the write data and the IC card body, and is considered reasonable.
However, with the increase in the amount of write data, there is a problem that it is difficult to adopt the conventional process.

Here, the conventional issuing process will be described with reference to the IC card manufacturing and issuing process flowchart (FIG. 4).
As shown in FIG. 4, the card base is first manufactured (S21). The manufacture of the card substrate is a well-known process in which printed core sheets and oversheets are laminated and press-laminated.
Next, a COT part recess for mounting the IC module is formed on the card base (S22). In parallel with these steps, COT acceptance inspection (S23) and adhesive tape pasting on the back surface of COT (S24) are performed. In the COT acceptance inspection (S23), a part of IC issuance (primary issuance) may be performed.

The IC card issuance process (S26) is performed after the COT mounting (S25) step. The COT mounting is a process in which the COT with the adhesive tape pasted is fitted into an IC module mounting recess excavated in the card base and lightly heated and fixed to fix the COT. Of course, this step is performed after individual IC modules are punched out of the COT. In the issuance process, in addition to the writing process (IC issuance) for the IC chip, character embossing, magnetic encoding, face photo printing, and the like are performed according to the card specifications.
The issuance process can be distinguished from an electronic issuance process that performs a writing process (IC issuance) on an IC chip and a physical issuance process that performs character embossing, magnetic encoding, facial photo printing, and the like.

In the COT stage, the reason why the IC is not issued until the secondary issue of the IC is that if the secondary issue process including the personal information is performed in the COT, each COT is punched out and mounted on the card. If it becomes difficult to specify what kind of individual issue is issued to the card, and if this cannot be specified, additional issue processing (for example, embossing, magnetic encoding, facial photo printing, etc.) is performed on the card surface. Can be difficult.
For this reason, normally, after a card is completed, a series of other physical issuance processes including IC issuance are performed. In particular, due to an increase in the amount of applications and stored data, recent IC cards have a very long time to issue an IC. In such a tendency, there is a problem that if IC issuance after completion of the card, the lead time for delivery from the order cannot be shortened.

The prior art which performs the IC card IC issue processing in the COT stage is not particularly detected. Patent Document 1 proposes to read information recorded in a memory of an IC card, search for corresponding information recorded in another medium using the information as a search key, and write the information to the IC card. This is performed after the completion of the IC card and has a different purpose from the present application.
Patent Document 2 relates to a technique for preventing unauthorized issuance, but also relates to issuance processing after the completion of an IC card.

Japanese Patent Laid-Open No. 9-44612 JP 2001-357358 A

As described above, recent IC cards tend to take a very long time to issue ICs due to an increase in the amount of applications and stored data. In other words, there is a problem that the lead time for delivery from the order cannot be shortened if the IC is issued after the card is completed.
Therefore, the present invention has been completed by studying to further shorten the lead time from order receipt to delivery.

(1) In the IC card issuance processing method according to the present invention (claims 1 to 4), at the COT stage, during the process of electrical characteristic inspection as the acceptance inspection that is normally performed, the necessary IC issuance 2 It is possible to perform the next issue processing. In a normal card-issuing machine, the number of cards that can be processed at one time is limited to a range of several to about 10 cards due to restrictions on the size of the card. Since the IC module can be accessed at one time, it is possible to perform issuance processing for 16, 32, 64 or more numbers at once in a batch processing unit, and the processing time can be greatly reduced. .

(2) Since IC issuance processing is possible immediately after COT is received, regardless of the card manufacturing process, processing time after IC card conversion is shortened, and lead time for manufacturing and shipping is greatly reduced. It becomes possible.
This is a medium that does not stick to card size, such as use in UIM (User Identity Module), which is expected to increase in use in mobile phones in the future, and new small UIM (mini-size UIM) that is further miniaturized. In response to an increase in the use of the card, it is possible to meet the increasing need to complete the issuance before COT mounting in accordance with the shipment of various shapes of media other than the card state.

(3) The IC module for IC card of the present invention (Claim 6 and Claim 7) is provided in the rewritable memory area of the IC chip, inspecting / issuing the module, issuance data file name, and issuance data file. Since the issuance identification data associated with the order is written, there is no error in post-processing such as embossing.

(4) The IC module for IC card of the present invention (Claims 6 and 7) is an issue in which the inspection / issue result of the module, the issue data file name, and the rank in the issue data file are associated with each other. Since the identification data is written in a rewritable memory area that does not affect the actual use of the IC chip (for example, a memory area that can be freely used by the user, a manufacturing history information area, etc.), No mistakes are made in the post-processing step. The write data can be erased. As a result, the memory area occupied by the issue identification data after it is no longer necessary can be used as a user area during actual use.

In addition, the history can be easily identified even when collected as a defective product.

The IC card issuance processing method, IC card IC module, and IC card of the present invention will be described below.
The IC card issuance processing method of the present invention is characterized in that issuance processing, particularly electronic data writing processing, is carried out at the COT stage when manufacturing contact IC cards and contact / non-contact IC cards. In this issuance process, a method for generating a module specific number and writing it to the IC chip (Claims 1 and 2) and a method for using a unique number originally recorded on the IC chip (Claims) 3 and claim 4).
In either case, there is no significant difference in the manufacturing process itself.

FIG. 1 is a chart showing an IC card manufacturing and issuing process flow according to the present invention.
As shown in FIG. 1, first, a card base is manufactured (S11). The card substrate is manufactured by laminating two front and back layers of a printed core layer with multiple faces and, if necessary, a transparent oversheet layer having a magnetic tape transferred to the outermost surface of the front and back, and applying heat pressure to the base. Fusion and integration of materials.
Thereafter, punching to individual card sizes is performed, and a sign panel, a hologram label, and the like are transferred as necessary. Next, a counterbore process for forming a COT part recess for mounting the IC module is performed (S12).

  In another process parallel to the processes of S11 and S12, COT acceptance inspection and IC issuance processing are performed (S13). Acceptance inspections are mainly performed automatically, such as manual inspections such as dimensions and appearance, and electrical characteristic tests performed using a dedicated tester. Initial defective products are identified, and COTs other than these are inspected and issued. A defective mark (drilling) is attached at a predetermined position to those determined to be defective by the COT inspection.

  The IC card issuance processing method according to the present invention (claims 1 to 4) is characterized in that the IC issuance is performed simultaneously with the COT acceptance inspection. IC issuance is all data writing, file setting, and application loading necessary for actual use as an IC card are performed for each IC chip at the COT stage. Issue identification data associated with an array of individual issue processing information is generated.

The issue identification data includes a case where a module specific number for specifying a COT array is generated and used, and a case where a unique number previously assigned to the IC chip is used. When writing this module specific number or unique number and attached data to a rewritable memory area that does not affect the actual use of the IC chip (for example, a memory area that can be freely used by the user, a manufacturing history information area, etc.) There are a case where only the module specific number is written (claim 1). This writing may be temporarily performed and erased after the card is completed.
The file setting means creation of a file, securing a memory area usable by the file in the IC chip, and the like. Generation of the module specific number means that serial numbers from the beginning to the end of the issuance processing information are mechanically assigned to the COT array. However, an irregular number (random number or the like) may be assigned from the viewpoint of security.

A feature of the IC card issuance processing method of the present invention (Claim 3) is that a unique number previously written in the IC chip is used, and this unique number is associated with the issuance identification data of the generated COT. . Therefore, the writing process to the memory area of the IC chip is not necessary.
Note that unique numbers that do not overlap each other are usually written on the IC chip.

  After the above steps, the adhesive tape sticking (S14) is performed in the same manner as the conventional method. This step is a step in which an adhesive tape or a liquid adhesive is laminated or coated on the back surface of the COT, or an adhesive is applied to the concave side of the card substrate. After that, only the non-defective IC module without the defect mark is punched and a piece of COT is mounted (S15).

The IC card issuance process (S16) is performed after the COT mounting process, but the IC issuance performed in the conventional issuance process is not performed in this issuance process.
The issuance process performed in this process is a physical issuance process, that is, a process such as character embossing, magnetic encoding, and facial photo printing, and is inherently limited to the process performed on the IC card substrate. Note that the steps after the COT mounting and the steps before that may be performed on different lines.

The IC card issuance processing method of the present invention has been outlined above, but will be further described with reference to the drawings and tables to make it easier to draw a more specific image.
FIG. 2 is a diagram showing COT at the time of acceptance, and FIG. 3 is a diagram showing COT after acceptance inspection.

  As shown in FIG. 2, in the COT 1, the IC modules 3 are arranged on the surface of the substrate 2 such as a tape-like glass epoxy. Each IC module 3 has a contact terminal plate 3t and a back circuit formed on the surface of the substrate 2, an IC chip is mounted on the back of the contact terminal plate, and each terminal of the IC chip and the back circuit are connected by wire. Yes. The IC chip and the wire connecting portion are resin-molded so as not to be damaged.

The size of one contact terminal board is often about 13.0 mm × 12.0 mm. Since the thickness of the tape base material 2 is about 100 μm and the height of the resin mold part is about 420 to 450 μm from the base material surface, it is a flat material as a whole.
Usually, the IC modules 3 are formed in a tape shape arranged in two rows. In the case of two rows, the width is about 35 mm. The shape of the contact terminal plate 3t is as shown in the enlarged view of FIG. In the case of FIG. 2, the younger numbers 1 and 2 are on the front side, and are punched first and mounted on the IC card. The opposite side is the side wound around the supply reel shaft.

  The two rows of IC modules are assigned module specific numbers for each COT 1, 2, 3, 4,. In the drawing, an odd number is assigned to the upper IC module, and an even number is assigned to the lower IC module. However, the present invention is not limited to this. The method of assigning the module specific number is arbitrary, but each manufacturing lot and type, COT number, date of manufacture, etc. can be identified.

In the case of FIG. 2, the COTs with module identification numbers 10 and 17 are hatched IC modules detected as defective products by the COT manufacturer, and are usually perforated and cannot be used. It has been clarified. Such an IC module is called an initial defective product.
It should be noted that the module specific number assigned to the IC module is not necessarily displayed so as to be actually visible. This is because the module number is recorded on the IC chip, and the numbering order is only required to be regularized so that the IC module corresponding to the module number can be identified.
As in the third and fourth aspects of the invention, when a unique number is used, it is associated with the unique number, so there is no need to attach a module specific number.

  FIG. 3 shows COT after acceptance inspection. In this figure, COTs with module identification numbers 3 and 22 are surrounded by a double frame. This indicates that a new COT defect has been detected in the acceptance inspection. The incoming inspection is performed on the COT excluding the initial defective product. However, since the inspection is performed based on a standard different from that of the manufacturer, a new defective product may be found. This is a defective product. In addition to inspection failures, issue failures due to write failures also occur, and these are combined to make inspection / issue defective products. A defective mark (drilling) is also attached to a predetermined position for inspected / issued defective products.

After the COT acceptance inspection, issue identification data that associates the module specific number with the inspection / issue result, the issue data file name, and the rank in each issue data file is created.
Table 1 is a table showing an example of creation of issue identification data.

In the case of Table 1 above, the first 10 to 10 of the issued data file A are issued, then the first 1 to 6 of the issued data file B are issued, and then the first of the issued data file C is issued. The case where 1 to 4 sheets are issued is shown.
In the issuance identification data, the first to sixth digits indicate the module specific number, the seventh digit indicates the inspection / issue result (including initial failure) identifier (0; OK, 1; NG), 8-10. The digit indicates the issue data file identifier (001; file A, 002; file B, 003; file C).

However, the issue identification data does not necessarily have the format of the above example. At least, the data for specifying the IC module is uniquely associated with the data for specifying the issue file name and the data order in the issue file. Just do it.
At this time, in order to associate each IC module with the issue identification data, the issued IC module specific number is written in the specific memory area of the IC chip.
If each IC module already has a unique number (not necessarily a serial number), it is not necessary to write the IC module specific number.

After this COT acceptance inspection, an IC is issued for writing the electronic data to the IC chip. Since the IC issuance process is not performed for the initial defective product and the inspection defective product, as shown in Table 1, they are not entered in the order column from the top of the issued data file.
Further, when a number (unique number) unique to the IC module is used, it can be considered that the module specific number in Table 1 is replaced with a unique number. There are various notation methods for unique numbers, and they are not unified, but it is said that duplicate numbers do not occur between IC chips.
Table 2 shows an example in which the first 10 of the issue data file A is issued when the IC module unique number (unique number) is used.

In the issue identification data in Table 2, the module number is displayed from the first to the fifth digit, the issue data file name is displayed from the sixth to eighth digits, and the order in the issue data file is displayed from the ninth to fourteenth digits. Yes.
Below, <issue data file> in which the issue identification data and the inspection and issue processing results for each IC module unit of COT are associated is displayed (Table 3, Table 4, and Table 5).
<Issued data file> is obtained by editing the data provided by the requester in advance and converting it into a format that can be issued by the issuing device.

The above Tables 3 to 5 are displayed in an easy-to-understand manner as an example, and the actual data is an ASCII code or other code, and other numbers and gender information are also appropriate codes (hexadecimal numbers, etc.). It is converted and displayed.
If <Issue Identification Data> is written on the IC chip, it is not necessary to record it on another recording medium such as a hard disk, floppy disk, or MO, but these are part of the issuance history information. You may make it record on a recording medium.
When writing only the module number into the IC chip, it is essential to record <issuance identification data>, which is the association information between the module number and the issuance data, on a recording medium such as a hard disk, floppy disk, or MO.

Next, the COT mounting issuing machine or the issuing process machine (character embossing, magnetic encoding, facial photo printing, etc.) in the subsequent process performs the above <issuing identification data file> and <issuing data file A> The contents of data file C> are read from a hard disk, floppy disk, MO, or the like. However, each issuance data file is usually in the same format as that used in the issuing machine, and is not specific to the present invention.
An IC chip memory data reader is installed in the COT mounting issuing machine or the issuing process machine in the subsequent process, and reads the module specific number written in the previous process or the unique number originally written in the IC chip. .

  An IC module corresponding to the module identification number (or unique number) of <issue identification data> is specified, and issue processing data corresponding to this is searched from <issue data file> to specify necessary data. Next, necessary issue processing (physical issue processing) is performed.

In the <issue data file>, main contents of electronic data to be recorded on the IC chip are recorded based on the arrangement information of Table 1 or Table 2. In the case of Table 3, Table 4, and Table 5, only the membership number, user name, and gender are displayed.
When actually performing the issuance process (physical issuance process) that is actually required, a more detailed issuance master file is required, which is managed as confidential information.
In the detailed issue master file, for example, the member name, address, expiration date, issue date, handling store code, account number, face photo data, and the like may be recorded.
Therefore, the <issue data file> is linked to the master file and is simply used for searching and calling the master file.

  By doing so, for example, with the COT inspection machine, it is possible to complete the final issuance (secondary issuance) required in the COT state, and to specify individual issuance processing information, and this is uniquely defined. The module specific number to be linked is temporarily written in a rewritable memory area in the IC chip, the data of both is correlated and recorded on a recording medium, and then added to character embossing, facial photo printing, and magnetic encoding , Etc. occur, use the recording medium, read the module identification number written in the IC chip, identify the issue information to be linked, and search for the issue information to be added, including the post process Thus, reliable individual information issuing processing (physical issuing processing) can be executed without error.

  The issuance identification data or data written in the IC module only contains the data for specifying the issuance processing sequence, and does not include the personal attribute data itself. There is an advantage that it is not necessary to consider special handling from the viewpoint of information protection, and handling becomes easy.

  As described above, the present invention has been described mainly with respect to the IC card issuance processing method. However, the IC card IC module of the present invention relates to the module specific number or the unique number, and the module inspection / issuance result and issuance data. It is clear that the issue identification data associated with the file name and the rank in the issue data file is the IC module in which the issue identification data is written. The IC card of the present invention means an IC card in which those IC modules are mounted.

  The IC card issued by the issuing processing method of the present invention is not limited to a wallet-sized IC card, but includes a UIM and a SIM (Subscriber Identity Module) used for a mobile phone as described above.

It is a chart which shows the manufacture issue processing flow of an IC card. It is a figure which shows COT at the time of acceptance. It is a figure which shows COT after an acceptance test. It is a chart which shows the manufacture issue processing flow of the conventional IC card.
