Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to a portable storage medium processing device that issues portable storage media such as IC cards.

(Prior art) Cards with magnetic stripes, so-called magnetic cards, which are generally used for identification cards or credit cards, have a small amount of stored data and are easy to read, so they have low security. There's a problem.

Therefore, portable storage media, so-called IC cards, which have high security against reading of stored contents and have a large storage capacity, are now being used. This type of IC card is usually handed over from the card manufacturer to the card issuer in an unissued state, and the card issuer writes predetermined data on it, issues it, and hands it to the user. .

By the way, in the conventional IC card issuance processing method, data written on a magnetic tape or floppy disk is directly input to a card reader/writer via a host computer, as in the case of conventional magnetic card issuance.
Unpublished 1. A method was used in which the card was issued by writing on the C card.

However, in such conventional processing methods, there is a very large possibility that the data written on the IC card will be easily leaked to the outside, and therefore there is a drawback that security for the processing device is poor.

(Problems to be Solved by the Invention) As mentioned above, in the conventional processing method, there is a very large possibility that the data written on the portable storage medium will be easily leaked to the outside, and therefore, the security is poor. There is.

SUMMARY OF THE INVENTION Therefore, the present invention aims to eliminate the above-mentioned drawbacks and provides a portable storage medium processing device with high security that is suitable for a portable storage medium with high security.

[Configuration of the Invention (Means for Solving Problems) The portable storage medium processing device of the present invention writes predetermined data to a portable storage medium, and a plurality of data holding devices holding data common to portable storage media to be written; a read/write control means for controlling reading and writing of data between these data holding devices and the portable storage medium; A host control means for controlling the reading/writing control means is provided, and each of the data holding devices has specific information that can be mutually confirmed between the data holding devices. After confirming whether or not there is a correct relationship, the read/write control means performs reading/writing.

(Function) Data can be read and written between the data holding device and the portable storage medium without going through the host means, so data does not easily leak outside and security is extremely high. It becomes expensive.

In addition, reading and writing are performed after confirming whether or not there is a correct relationship between each data holding device, so it is possible to prohibit the use of forged or incorrect data holding devices, thereby further improving security. can be increased.

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings.

FIG. 3 shows an example of a portable storage medium according to the present invention.
The appearance of an IC card with a magnetic stripe after being issued is shown. That is, 1 is a card body, which is made of, for example, a rectangular thin plastic plate. A magnetic stripe 2 is provided at the end of the front surface of the card body 1 in the form of a strip in the longitudinal direction. In addition, on the surface of the card body 1, embossed information 3 is written on an embossed print.
is formed. The embossed information 3 includes, for example, the name of the card holder, the account number, and the expiration date of the card.
It consists of identification information of the cardholder.

Furthermore, the surface of the card body 1 is electrically connected to an integrated circuit (IC) 4 embedded in the card body 1, and serves as an input/output terminal for electrical contact with a card reader/writer (not shown). A contact portion 5 is provided. The integrated circuit 4 includes a control section (for example, a microprocessor) 6 and a memory section (for example, an EEPROM) 7. In addition, emboss information 3 is required before issuance.
is not formed.

FIG. 2 shows an external perspective view of an IC card processing device that issues IC cards as an example of a portable storage medium processing device according to the present invention, and FIG. 1 shows a block configuration diagram thereof. That is, 11 is a host control unit, which includes a host processor 12 consisting of a control section (not shown) and a memory section containing a control program, and a hard disk drive 13 that stores a program for controlling the entire apparatus and the processing contents of the apparatus. and a floppy disk device [14] for inputting data that is part of the data to be written on the IC card and that differs from IC card to IC card, such as the name of the card holder and the account number in the case of a cash card. This is the host for the device that will be used. Similar to the floppy disk device 14, 15 is a magnetic tape unit for inputting different data for each IC card, and is connected to the host processor 12, and is used by an IC card issuer for its services, for example. It is also possible to use the magnetic tape created by the magnetic tape unit of the host computer from the list of new subscribers registered in the host computer of the system.

16 is a keyboard for performing various operations, and 17 is a CRT display device for displaying operating procedures, status, etc., and these are connected to the host processor 12.

18 is a card reader/writer, and the host processor 12
It is possible to insert an access key card AC to activate the device. Here, as the access key card AC, for example, an IC card similar to the IC card shown in FIG. 3 is used.

However, it is assumed that the magnetic stripe 2 and the embossed information 3 are not provided.

19 is a printer that creates a shipping note for shipping the issued IC card to its owner, and 20 is a printer that sends the card holder's temporary PIN (which can be changed by the card holder) to the IC card holder. is a printer that creates an issuance notice 21 for separate notification, and these printers are connected to the host processor 12. The issuance notice 21 created by the printer 20 is structured as shown in FIG. 5, for example. That is, an envelope-shaped issuance notice 121 is formed on two stacked sheets of paper 22 with a peripheral edge (hatched area 23) glued in advance, and can be cut at a perforation 24 provided on the peripheral edge. There is. Then, on this issuance notice 21, address/name 25 and temporary PIN number 2
6 etc. will be printed. In this case, the area where the address/name 25 is printed will also be colored on the first sheet on the front, and the area where the temporary PIN number 26 will be printed will be colored only on the front (inside) of the second sheet on the back, and the area where the temporary PIN number 26 will be printed will be colored only on the front (inside) of the second sheet. is designed not to develop color. As a result, the temporary PIN number is written so that only the cardholder can know it.

27 is an issuance processing unit that processes the IC card to be issued, and is connected to the host processor 12. The issue processing unit 27 is configured as follows. That is, 28 is a microprocessor, and host processor 1
11111 for writing magnetic data on the IC card issuing subsection, that is, the magnetic stripe 2 of the IC card, control for forming embossed information 3 on the IC card, and writing data in the memory section 7 of the IC card according to instructions from 2. Inclusion system
etc. A keyboard 29 and a display T 30 are connected to the microprocessor 28.

The keyboard 29 is used for inputting a password, testing the book issuing processing unit 27, resetting in case of trouble, and the like. The display 30 displays the status of the main issue processing unit 27, the results of test operations, and the like.

Unissued IC cards are stacked and stored in a hopper 31, and are taken out one by one in response to a signal from the microprocessor 28. The IC card taken out from the hopper 31 is sent to an encoder section 32 in which magnetic data is written.
sent to. After a detector (not shown) detects that the IC card has arrived at the encoder 32, the microprocessor 28 writes magnetic data on the magnetic stripe 2 using a read head (magnetic head) (not shown). After writing is completed, the microprocessor 28 reads the written data, checks whether the written data is correctly written, and then sends the IC card to the embossing unit 33.

If the written data is incorrect, the magnetic data is written again and then checked. If the writing still cannot be done correctly, the data passes through the embossing unit 33, further passes through the reader/writer unit 34, and is sent to the destruction unit 35, where, for example, as shown in FIG. open it. This results in
To make an IC card unusable and to visually determine that it is a defective IC card. Further, if the emboss information 3 has been formed, a hole 9 is also made in the emboss information 3 portion as shown in FIG. 4, for example. Regarding electrical recording, it is possible to write a void command in the memory section 7 so that the IC card cannot be used by the control section 6 of the IC card, so it is not necessarily necessary to destroy the IC card by drilling a hole or the like. This not only makes it impossible to use this IC card in a terminal that can use it, but also makes it possible to determine that this IC card cannot be used without using a device. The punching of the magnetic stripe 2 and the embossed information 3 and the writing of a void command into the memory section 7 are performed in the following manner.

The first is when the magnetic stripe 2 is defective, the writing to the magnetic stripe 2 is completed normally but there is an error in the middle of forming the embossed information 3, and the second is when the embossed information 3 is formed normally. and cases where the embossed information 3 is formed normally but not normally (for example, when the last digit of the account number is embossed with an incorrect number) and it is impossible to write to the memory unit 7. It is. Third, although the magnetic stripe 2 and emboss information 3 are normal, a part of the memory section 7 is defective, so it is not a normal IC card, but the terminal that can use this IC card is partially used. If possible.

In the first case, a hole 8 is made in the magnetic stripe 2 by the destruction unit 35, and a hole 8 is made in the magnetic stripe 2 by the reader/writer unit 34.
A void command is written in the memory section 7. Although the emboss information 3 is not formed at all, it is incomplete and can be determined by looking at it, so there is no need to make holes with the destruction unit 35.

In the second case, since the magnetic stripe 2 is written normally and the embossed information 3 is formed normally, each part of the magnetic stripe 2 and embossed information 3 is punched by the destruction unit 35. Let's do it. Since it is not possible to write into the memory section 7, there is no need to write a void instruction using the reader/writer unit 34 (in fact, it is impossible to write the void instruction itself).

In the third case, each part of the magnetic stripe 2 and embossed information 3 is punched by the destruction unit 35, and a void command is written in the memory section 7 by the reader/writer unit 34.

After the above-mentioned unusable processing is performed on the defective IC cards, they are sorted by the sorting section 36 and are stacked in the reject stacker 37.

The IC card on which magnetic data has been normally written and sent to the embossing unit 33 has embossed information 3 formed thereon. Here, we generally use character types (
Although raised characters are formed on the upper side by pressing (convex and concave), raised characters may also be formed by pasting characters. When forming emboss information 3 by pressing a character mold, the position of the press mold for each character is checked, and the microprocessor 28 checks whether or not the emboss is done correctly. Immediately after this happens, embossing is stopped and the above-mentioned unusable process is performed. Of course, the data to be embossed is controlled by the microprocessor 28.

When the embossed information 3 is normally formed, the IC card is sent to the reader/writer unit 34, and the contact portion 5 of the IC card is placed at the contact position of the reader/writer unit 34.
came and was stopped. After that, the reader/writer unit 34
The microprocessor 28 controls the contact portion (not shown) of the IC card so that it comes into contact with the contact portion 5 of the IC card.

When the microprocessor 28 inputs a signal to the read/write control section 39 indicating that the contact of the contact section 5 has been completed, the read/write control section 39 supplies power to the control section 6 and the memory section 7 via the contact section 5. and sends a start signal (command).

After receiving a reply signal (response) from the IC card control unit 6, the read/write control unit 39 reads the key card KC and the card reader/writer inserted into the card reader/writer 40 connected to the read/write control unit 39. Writer 41
The data from the fixed data card FC inserted into the IC card is written into the memory section 7 of the IC card and checked. Here, when the read/write control unit 39 confirms that the data has been written normally, the read/write is completed! l
Upon receiving the signal from the control unit 39, the microprocessor 2
8 controls the reader/writer unit 34 to separate the contact section (not shown) from the contact section 5 of the IC card. Thereafter, under the control of the microprocessor 28, the ICs that have passed through the destruction unit 35 and are placed in the sorting section 36 are placed in the stacker 38 for which all writing has been completed normally.
Cards are collected. Here, as the key card KC and the fixed data card FC, for example, an IC card similar to the IC card shown in FIG. 3 is used.

However, it is assumed that the magnetic stripe 2 and the embossed information 3 are not provided.

The three components of magnetic data, embossed information, and electronic recording are finally brought to the electronic recording unit, i.e., the reader/writer unit 34.

This is so that since the embossed information is written using a press, the integrated circuit 4, contact portion 5, etc. can be recorded on an undamaged IC card during this operation, that is, the product can be checked.

In addition, in FIG. 2, 42 is the I in the stacker 37°38.
This is an exit door for taking out the C card.

FIG. 6 shows the contents of the memory section 50 of the access key card AC. 51 is a control program area, 52 is a terminal access code area, 53 is a card access code area, 54 is a pin number area, 55 is a user name (code) area, 56 is a void area, 57 is an error count area, and 58 is an issue area. This is the recording area.

FIG. 9 shows the contents of the memory section 7 of the IC card after it is issued. 91 is a basic control program area, 92 is a manufacturer record area, 93 is a publisher record area, 94 is an issue record area, 95 is an application program area,
96 is a carrying person recording area, and 97 is an empty area.

Next, the operation of the above configuration will be explained with reference to the flowchart shown in FIG.

First, when you turn on the power to this device, the host processor 1
Step 2 performs initial settings, and if there are no problems, displays a message "Insert the access key card" on the display device 17 (Sl). Here, the operator inserts the access key card AC into the card reader/writer 18 (S2). Then, the access key card AC is supplied with power and activated, and a check is made between the access key card AC and the host processor 12 to see if the inserted access key card AC is compatible with this device. be done (33.34). This compatibility verification is performed, for example, in the following manner.

That is, a terminal access code is stored in the terminal access code area 52 of the memory section 50 of the access key card AC, and by requesting this terminal access code from the host processor 12 and returning it to the host processor 12, the host It is compared with a code registered in the processor 12. Next, the host processor 12 sends the card access code to the access key card AC, and the access key card A is checked against the card access code in the card access code area 53 of the memory section 50.
Do this in C. By any method, it is verified that the host processor 12 and the access key card AC can access each other. If the host processor 12 and the access key card AC cannot be matched here, the access key card AC is connected to the card reader.
It is ejected from the writer 18 (85), and the entire process ends.

Note that since the access key card AC was different, if another access key card AC is used, the process will start from the first step.

In step S4, if the host processor 12 and access key card AC are matched, the host processor 12 displays the message "Enter your PIN" on the display device 17.
A message is displayed (S6). Here, the operator inputs the secret IElt code using the keyboard 16 (S7). This entered PIN number is sent to the access key card AC by the host processor 12, and is sent to the access key card AC within the access key card AC.
The control unit (not shown) of C and the ilJ WJ program in the control program area 51 of the memory unit 50 compare the password with the password in the password area 54 (38). If the password does not match here, If so, the error count area 57 of the memory section 50 is checked (S9). For example, if the number of discrepancies reaches 3, it means that the access key card AC cannot be used.
I l[I If controlled by the control program in the program area 51, check whether the number of mismatches (number of errors) is three. Here, if the number of mismatches has not reached three, the value in the error count area 57 is counted up by one (S10),
Although the message "Password code not verified, please enter the code again" is displayed on the display device 17, the operation returns to step S6. Then you will have to enter your PIN again. On the other hand, if the number of mismatches has reached three, a void command is written in the void area 56 of the memory section 50 (S11), and the access key card AC cannot be used thereafter. This method is carried out, for example, by issuing an unusable code instead of the terminal access code when verifying the host processor 12 and the access key card AC. In this manner, when the access key card AC is voided, the contents of the user name area 55 of the memory section 50 are read out, and the user name, unverified comments, date, etc. are printed by the printer 19 (S12 ), the entire process ends after this printing is completed. In addition, after the user's name is read before the above printing, the access key card AC is read out by the card reader/writer 18.
is discharged from.

If the passwords match in step S8, the host processor 12 causes the display device 17 to display a message "insert key card" (813). Here, the key card KO is inserted into the card reader/writer 40 (S14), and the key card KC and read/write υI! The three II units verify that the host processor 12 and access key card AC can access each other in the same manner as described above (815, 816). If the key card KC and the self-reading control section 39 cannot be matched here, the key card KC is ejected from the card reader/writer 40 (S17). If you have a new keycard KC, i.e. if you have inserted a different keycard KC by mistake, you can insert another correct keycard KC.
(818). If there is no other key card KC, press the end key on the keyboard 16 (819). Then, after the contents of the user name area 55 of the memory section 50 of the access key card AC are read out, the access key card AC is ejected from the card reader/writer 18 (820).

At the same time, the printer 19 prints the user's name read from the user's name area 55 together with the date (521), and after this printing is completed, the entire process ends.

In step S16, when the key card KC and the read/write III til1 section 39 are matched, the host processor 12 receives a signal to that effect from the read/write control section 39 via the microprocessor 28. The message ``Enter your password'' is displayed on the screen (S22). Here, the password is input using the keyboard 29 <823). If the administrator, rather than the operator using the access key card AC, enters this PIN number, the IC card
This will improve the security of card issuing operations. In addition, since the password is entered using the keyboard 29 provided in the issuing processing unit 27 instead of using the keyboard 16, security is improved as there is no wiring to the outside to prevent eavesdropping during the process. being admired.

The password entered on the keyboard 29 is sent to the key card KC by the microprocessor 28 via the reading/writing control section 39, and is sent to the key card KC's control section (not shown) and the memory section 6o within the key card KC. The control program in the control program area 61 is compared with the password in the password area 65 (S24). The verification result is sent from the key card KC to the read/write control unit 39 and further sent to the host processor 12 via the microprocessor 28. Therefore, the display of the verification result (match, mismatch) can be confirmed on the display \i location 17, but the verification result is also displayed on the display 30 of the issuance processing unit 27, and the issuance processing unit 27 displays the password of the key card KC. It is easy to operate for people who are inputting information.

If the passwords do not match in step S24, the error count area 70 of the memory unit 60 is checked (825). For example, if the number of discrepancies reaches 3, if the key card KC is not usable and is controlled by the control program in the control program area 61, the number of discrepancies (errors) will be 3. Check whether or not. Here, if the number of mismatches has not reached three, the value in the error count area 70 is counted up by one (826), and the display W117
The message [PIN code not verified, please enter the pin number again] is displayed, but the operation returns to step 822. Then you will have to enter your PIN again. On the other hand, if the number of mismatches has reached three, the memory unit 60
A void command is written in the void area 69 of (827)
, the key card KC cannot be used thereafter.

This method is carried out, for example, by issuing an unusable code instead of the terminal access code when checking the read/write control section 39 and the key card KC. In this way, when the key card KC is voided, the contents of the user name area 55 of the memory 155o of the access key card AC and the contents of the user name area 66 of the memory section 60 of the key card KC are read out. After
The access key card AC is ejected from the card reader/writer 18, and the key card KC is ejected from the card reader/writer 40. At the same time, the printer 19 prints the user name read from the user name area 55, the user name read from the user name area 66, unverified comments, and the date (828).
. After such processing, the book! The 5-position operation is finished and if you want to restart it, you need to start from the beginning.

If the passwords match in step S24, the host processor 12 causes the display device 17 to display a message "Insert fixed data card" (829). Here, Fixed Data Card FC
is inserted into the card reader/writer 41 (830). Then, the fixed data card FC and the reading/writing control section 39 are connected to the above-mentioned reading/writing control section 39 and the key.
Verification is performed in the same manner as when the card KC and the card KC are verified to be mutually accessible (831, 832)
. If it is not possible to match the fixed data card FC with the read/write υJl11 part 39,
The fixed data card FC is ejected from the card reader/writer 41 (833). If there is a new fixed data card FC, i.e. if you have inserted a different fixed data card FC by mistake, you can insert another correct fixed data card FC (834), another fixed data card. F.C.
If not, press the end key on the keyboard 16 (8
35). Then, the memory section 5 of the access key card AC
0 user name area 55 and key card K
When the contents of the user name area 66 of the memory section 6o of the computer are read out, the access key card AC is ejected from the card reader/writer 18 and the key card KO is ejected from the card reader/writer 40 (S36). At the same time, the user name and user name area 6 are read out from the user name area 55 by the printer 19.
The user's name, comment, date, etc. that continue from 6 are printed (S37). After such processing, the operation of the apparatus ends, and if it is to be operated again, it must be restarted from the beginning.

In step 832, the fixed data card F
If C is compared with the three read/write control units, then the fixed data card FC is compared with the key card KC (838°539). This verification is performed, for example, by reading the issuing code in the issuing code area 82 of the memory section 80 of the fixed data card FC by the reading/writing control section 39 and sending it to the key card KC. This is done by comparing the issue code in the issue code area 62. Key card KC and fixed data card F
Both of C are used as a pair, so it is necessary to perform the above verification. Fixed data card FC has different issuers but is used in the same way (for example, if ○○ bank and XX bank are affiliated and can be used with each other, it will be the same application)
, it is effective to separate the key card KC and fixed data card FC. In this case, the issuance code area 82 of the memory section 80 of the fixed data card FC
By creating multiple issuance codes within the key card KC, it becomes possible to deal with key cards KC from different issuers. Of course, key card KC
Fixed data card FC data (issued I
By storing all the data to be written in the C card, it is also possible to start the device using only the key card KC. In this case, initial settings can be made using the keyboard 29 of the issue processing unit 27.

In step 839, if the key card KC and the fixed data card FC cannot be matched, the process proceeds to step 333 in which the fixed data card FC is ejected, and the above-mentioned fixed data card FC and three reading/writing control units are connected to each other. The same processing as when no match is made is performed.

In step 839, if the key card KC and fixed data card FC are matched, a signal to that effect is read and written to the microprocessor 2 by the write control unit 39.
8, the host processor 12 causes the display W117 to display a message "Enter your password" (840). Here, the user inputs the password using the keyboard 29 in the same way as inputting the password of the key card KC (841). This is also a key card
Access key card AC in the same way as entering KC's PIN number
If the administrator rather than the operator using the IC card issues the IC card, the security of the IC card issuing operation will be improved.

The password entered on the keyboard 29 is sent to the fixed data card FC by the microprocessor 28 via the reading/writing control unit 39, and is sent to the fixed data card FC within the fixed data card FC.
The control unit (not shown) of C and the control program in the control program area 81 of the memory unit 80 perform verification against the password in the password area 85 (S42
). This verification result is sent from the fixed data card FC to the read/write control section 39 and further sent to the host processor 12 via the microprocessor 28. Therefore, the display of the verification result (match, mismatch) can be confirmed on the display device 117, but the verification result is also displayed on the display 30 of the issuance processing unit 27, and the issuance processing unit 27 confirms the password of the fixed data card FC. It is easy to operate for people who are inputting information.

If the PIN numbers do not match in step 842, the error count area 88 of the memory unit 80 is checked (S43). For example, if the number of mismatches reaches 3, it is determined that the fixed data card FC cannot be used. If it is controlled by the control program in the program area 81, it is checked whether the number of mismatches (the number of errors) is three. Here, if the number of mismatches has not reached 3, the error count area 8
The value in 8 is incremented by one (544), and the message "Password number mismatch, please enter the password again" is displayed on the display device 17, but the operation returns to step 840. Then you will have to enter your PIN again. On the other hand, if the number of mismatches has reached three, a void instruction is written in the void area 87 of the memory section 80 (
S45), the fixed data card FC cannot be used thereafter. This method is performed by, for example, outputting an unusable code instead of the terminal access code when comparing the read/write control unit 39 with the fixed data card FC. In this way, if the fixed data card FC is voided,
The contents of the user name area 55 of the memory section 50 of the access key card AC and the fixed data card FC
After the contents of the user name area 86 of the memory section 80 are read out, the access key card AC is ejected from the card reader/writer 18 and the fixed data card FC is ejected from the card reader/writer 41. At the same time, the printer 19 prints the user name read from the user name area 55, the user name read from the user name area 86, unverified comments, date, etc. (846). After such processing,
The operation of this device has ended, and if it is to be operated again, it must be started from the beginning.

If the passwords match in step S42, the host processor 12 causes the display device 1117 to display a message "Enter data" (S47).

Here, the floppy disk (or magnetic tape), which is a file of different data for each IC card to be written to the IC card to be issued, is transferred to the floppy disk device 1.
4 (or magnetic tape unit 15) (
S48). Next, an unissued IC card is set in the hopper 31 of the issuing processing unit 27 (S49). next,
By pressing the start key on the keyboard 16 (S50), the startup of this device is completed.

The read/write control section 39 reads the contents of the issued number area 71 (the number of issued sheets written in advance by the administrator and is to be issued this time) and the issued count area 72 of the memory section 60 of the key card KC, and stores both contents. Compare,
When the contents of the issue number area 71 are larger than the contents of the issue count area 72, a signal indicating that there is an issue number is sent to the host processor 12 via the microprocessor 28.

As a result, the host processor 12 reads the IC card issue data from the floppy disk device 14 and sends it to the microprocessor 28.

Then, the microprocessor 28 outputs the data from the hopper 31 (
Take out one C card (851). When the removed IC card comes to the encoder 32, the microprocessor 2
8 writes the data sent from the host processor 12 onto the magnetic stripe 2 of the IC card (852). After the writing is completed, the microprocessor 28 reads the corrupted data and compares it with the data stored in the microprocessor 28 and sent from the host processor 12.
It is checked whether the written data is correctly written (853). If this check indicates that the writing is incomplete, the microprocessor 28 writes the data again (854). Then, check again (S5
5) If the writing is still incomplete, the IC card is considered defective and sent to the destruction unit 35, a hole 8 is punched in the magnetic stripe 2 (S56), and the IC card is sent to the destruction unit 35.
are accumulated in the reject stacker 37 (857
). Then, the record is recorded on the hard disk device 13 by the host processor 12. When the defective IC cards are accumulated in the reject stacker 37, the microprocessor 28 returns to step S51, and the hopper 3
The next IC card will be taken out from 1.

If the writing is normal in the check at step 853 or 855, the IC card on which the magnetic data has been written is sent to the embossing unit 33, and embossed information 3 is formed by the microprocessor 28 (358).

Since the embossing is performed by pressing one character at a time, the microprocessor 28 performs the embossing while checking the pressed character position one character at a time (859).

Therefore, when one character is erroneously embossed during embossing, the embossing is stopped and the IC card is sent to the destruction unit 35 as defective (S60). The embossed information is usually at least the number (account number in banks) and name of the person carrying the IC card, so if it forms one line of either of these, or both, it is impossible to use it fraudulently. Destroy the embossed information 3 part.

Here, in order to emboss the wearer's number first, a hole 9 is made in the part corresponding to the number using the destruction unit 35.

In this case, the progress of embossing formation is determined (the microprocessor 28 checks the point at which embossing is interrupted).
(S61), the microprocessor 28 either punches only the magnetic stripe 2 (862) or
Holes are punched (863) for both the embossed information 3 and the embossed information 3, and the process then proceeds to step S57 where they are stacked on the reject stacker 37.

When the embossed information 3 is accurately formed, the IC card is sent to the reader/writer unit 34, and the contact part 5 comes to the contact position of the reader/writer unit 34 and is stopped. Then, the microprocessor 28 controls the contact section (not shown) of the reader/writer unit 34 to come into contact with the contact section 5 of the IC card, and then sends a signal indicating that the contact section has been brought into contact to the read/write control section 39. . Read/write control section 3 that receives this signal
9 supplies power to the control section 6 and memory section 7 of the IC card, and performs initial signal exchange. (Therefore, it is possible to send and receive initial signals). When the initial signal exchange is completed, the key card KC is compared with the issued IC card via the read/write control section 39 (864, 8).
65).

This verification method is performed, for example, by verifying the issuer's temporary PIN number. It is considered that when an unissued IC card is handed over from a manufacturer to an issuer, a password is set for the exchange between the manufacturer and the issuer to prevent unauthorized use by a third party. Furthermore, since this PIN is required only when the IC card is delivered, the issuer's temporary PIN is used as a separate PIN after the IC card is issued. Verification using the issuer's temporary PIN is performed in the following manner. First, the read/write control unit 39 reads out the issuer temporary PIN number in the issuer temporary PIN area 67 of the memory unit 60 of the key card KC, and sends it to the control unit 6 of the IC card to be issued. The control unit 6 reads the temporary issuer PIN written by the manufacturer in the issuer recording area 93 (area where data such as issuer name and issuer code are written) of the memory unit 7, and reads the issuer temporary PIN number from the read/write control unit 39. Check it against the issuer's temporary PIN number sent from. If the issuer's temporary PIN does not match after this verification, the IC card is sent to the destruction unit 35 (866
), the magnetic stripe 2 and the embossed information 3 are widened (S67), and then the process proceeds to step 857 where they are stacked on the reject stacker 37.

If the issued board PINs match in step S65, fixed data in the issuer record area 93 and application program area 95 of the memory section 7 and variable data (carrier (name, account number, etc.) (86
8). This writing is performed as follows. First, fixed data is read from the data area 89 of the memory section 80 of the fixed data card FC and written into the memory section 7. The contents of the fixed data include the application program written in the application program area 95,
These include area divisions of the issue record area 94 and the bearer record area 96. When writing of this fixed data is completed, the contents of the issuer record area 68 of the memory section 60 of the key card KC are read out and the contents of the issuer record area 68 of the memory section 7 are read out.
Write in 3. Reading of data from the fixed data card FC and key card KC and writing of data to the memory section 7 are all performed by the read/write control section 39. When the writing of these data is completed, the read/write control unit 39 writes the variable data for the wearer sent from the host processor 12 via the microprocessor 28 into the wearer recording area 96 of the memory unit 7.

In this way, when data writing to the memory section 7 is completed,
The read/write υj@ unit 39 reads the written data and checks the layered data in the memory unit 7 by comparing it with the data from the fixed data card FC, key card KC, and host processor 12 (8
69). As a result of this check, if the writing is defective, 1 is written into the memory section 7 again (S70). However, if there is a write failure again (871) and the application is possible to some extent (S72), void data is written to the issue recording area 94 of the memory unit 7 so that it cannot be used (S72).
74). Those that cannot write void data are
The IC card is directly sent to the destruction unit 35 as a defective IC card, and holes are punched in the magnetic stripe 2 and embossed information 3 portions (873, 875), and then step 857
Then, they are accumulated in a reject stacker 37. Of course,
When a defective IC card is accumulated in the reject stacker 37, it is checked and sent to the read/write control section 39 via the microprocessor 28, so that it is stored in the defect count area 73 of the memory section 60 of the key card KC.
One content will be uploaded and recorded. This information is also recorded when a defective IC card is stacked in the reject stacker 37 in the same way when the encoder 32 and the embossing unit 33 become defective. Of course, the data is also recorded on the hard disk drive 13 of the host processor 12.

If the writing is normal in the check in step S69 or 871, read/write! The jlll1 unit 39 calculates the temporary carrier PIN number using random numbers (876), and writes the calculated temporary carrier PIN number in the carrier recording area 96 of the memory unit 7 (877).

Next, the three rust removal write control units read the cumulative issuance value from the cumulative issuance area 74 of the memory unit 60 of the key card KC, add 1 to the cumulative issuance value, and issue the resulting value to the issuance record area 94 of the memory unit 7. Enter J as the number (878). At the same time, the user's name (or code) is read from the access key card AC, key card KC, and fixed data card FC and written into the issuance recording area 94 of the memory section 7. When this is completed, the read/write control section 39 starts the basic control program area 9 of the memory section 7.
Write non-rewritable hold data in 1 (879)
It is not possible to rewrite anything other than the pin number that is the bearer's nap card number or the part that the bearer writes in when receiving service. Then, this IC card becomes issued and is sent to the stacker 38 to be accumulated (882). Further, the read/write control section 39 controls the memory section 60 of the key card KC.
Each of the contents of the issuance count area 72 and the issuance cumulative area 74 is incremented by 1 (S80). Step 8
After writing the hold data in step 79, the host processor 12 sends the IC card to the printer 19. All this data is stored on a floppy disk! An issuance notice with the mobile phone PIN code calculated above printed by the printer 20! 21 (881).

When the bearer's nap card number is printed by the printer 20, the memory in the read/write control section 39 is erased, thereby making the nap card number extremely secure.

When the read/write control section 39 counts up the issuance count area 72 of the memory section 60 of the key card KO, it compares the number with the content of the issued number area 71 to determine whether the number of issued cards has reached the planned number. It is checked whether or not (S83). As a result of this check, if the planned number of cards has not been reached, a signal to that effect is sent to the host processor 12, so after receiving the data from the host processor 12, the microprocessor 28 takes out one IC card from the hopper 31 ( 851).

As a result of the check in step 883, if the scheduled number of copies has been reached (if the content of the issue count area 72 after counting up is the same as the content of the issue number area 71), the issue ends. Of course, even if there is data to be issued to the host processor 12 side, the issuance ends.

Note that before writing the hold data in step S79, the serial number written in the manufacturer record area 92 of the memory section 7 (a serial number is attached to each IC card manufactured by the manufacturer and By reading out the stored number) and writing it in the issuance record area 75 of the memory section 60 of the key card KC as the serial number of the issued IC card, it is possible to check the IC card including the manufacturing number, which is effective for management.

When the issuance is completed in this way, the read/write control section 39 writes the contents of the issuance count area 72 and defective count area 73 of the memory section 60 of the key card KC together with the date in the issuance record area 75 (884), and then 72 and the contents of defective count area 73 are cleared respectively. Since the content of the cumulative issue area 74 is the total number of issues issued so far, it remains unchanged and becomes the final issue number. When this writing is completed, the host processor 12 causes the display device 17 to display a message "Press the end key" (885). Here, press the end key on the keyboard 16 (S
86). Thereby, the host processor 12 prints out the issuance record stored in the hard disk device F13 using the printer 19 (887). This publication record is
For example, as shown in FIG. 11, the serial number read from the IC cards issued in the order of issue number, the name and address of the bearer input by the floppy disk device 14 (or magnetic tape unit 15), etc. are printed. . In addition, by opening the outlet door 42 of the issue processing unit 27, the reject stacker 37 and the stacker 3 can be removed.
The defective IC card and the issued IC card are taken out from 8 (888). In addition, defective IC cards have holes punched in at least the magnetic stripe 2 or both the magnetic stripe 2 and embossed information 3, so it is easy to distinguish them from issued IC cards. It has become.

Thereafter, when the end key is pressed again on the keyboard 16 (889), the host processor 12 writes the issuance date and issuance record area 58 of the access key card AC in the same way as the issuance record was written to the key card KC. The number of sheets, number of defective sheets, key card code, fixed data card code, etc. are written (S90), thereby recording what kind of sheet was issued, when and how many sheets were issued.

Then, the access key card AC, key card KC, and fixed data card FC are ejected (
S91), all operations of this device end. .

The IC card processing device described above is a key card KC and a fixed data card FC that hold fixed data common to IC cards to be written to unissued IC cards.
Using these cards KC.

By reading and writing data between the FC and the unissued IC card, the above fixed data is written to the unissued IC card. Reading and writing of data between the two is performed by the microprocessor 28 and the read/write controller 39. As a result, the above card KC.

Since data can be read and written between the FC and the unissued IC card without going through the host processor 12, the data written to the unissued IC card will not easily leak outside. Security becomes extremely high.

In addition, the key card KC and the fixed data card FC store specific information that can be confirmed between each other, such as an issue code, and by comparing these issue codes within the key card KC, the key card KC and fixed data card FC can be exchanged. Whether there is a correct relationship with the fixed data card FC (for example, whether the issuing codes match or not)
After confirming the information, the three reading/writing control units perform reading/writing, so that, for example, a forged card KC can be detected.
, FC or the wrong card KC, FC can be prohibited, and security can be further improved.

Note that the present invention is not limited to the above-mentioned embodiments, and various modifications can be made. For example, instead of the key card KC and its card reader/writer 40, a data holding device including a control unit and a memory unit that can store information that identifies the user and perform internal verification may be used, and the read/write control unit 39 may be used. It is conceivable to connect them with detachable contacts.

Similarly, the fixed data card FC and its card reader/writer 41 are also data storage devices equipped with a control unit and a memory unit that can store and internally check information that identifies the user, and control reading and writing. What is part 39?
It is conceivable to connect them with removable contacts. In addition, although a PIN number was used to identify the user of the key card KC and fixed data card FC, it is also possible to memorize the user's physical characteristics such as fingerprints or signature, and use that information for verification. be. In that case, the keyboard 29 of the issuing processing unit 27 needs to be provided with means for inputting fingerprints, signatures, etc.

Further, in the embodiment, an IC card is issued by writing predetermined data to an unissued IC card.
Although the case has been described in which the present invention is applied to a C card processing VT system, the present invention is not limited to this.
The present invention can be similarly applied to an IC card processing device that damages initialization data and the like on an IC card during the card manufacturing stage.

Further, in the above embodiments, the case where the portable storage medium is a TC card with a magnetic stripe has been described, but it can be similarly applied to the case of an IC card without a magnetic stripe or an optical memory card called a laser memory card. .

[Effects of the Invention] As described in detail above, according to the present invention, it is possible to provide a portable storage medium processing device with high security suitable for a portable storage medium with high security.
