Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a magnetic card issuance system, and in particular, when issuing a magnetic card, management information such as the person who issued the card, the device that issued the card by operation, and the date and time of issuance is written on the magnetic stripe of the magnetic card. The present invention relates to a method for managing a magnetic card, which can write information together with other information and reliably manage the magnetic card after it has been issued.

Traditionally, credit cards are magnetic cards, which are thin plastic cards with magnetic stripes pasted on them.

It was widely used for ID cards, hospital consultation tickets, library and hotel tickets, etc. When issuing a conventional magnetic card, a card issuing machine writes unique information such as the holder's name, address, and credit rating on the magnetic stripe.
When needed, the magnetic cards entrusted to them by their holders were used for tasks such as reading, checking, and tabulating them with registers and terminal devices. However, with conventional magnetic cards, information about the holder is written and recorded on the magnetic stripe.
No information regarding the issuance of the magnetic card is written, and if a follow-up investigation is required due to an accident, forgery, verification, etc., the information regarding the issuance is recorded online from the terminal device to the host computer and recalled. If so, h
This requires a lot of work, and if the host computer is down, it may not be possible to track the magnetic card.

In view of the above-mentioned drawbacks of VC, the present invention provides a magnetic card management method in which management information regarding the issuance of a magnetic card is also written on the magnetic stripe when the magnetic card is issued, and the magnetic card itself can also be managed. .

Next, the operation of this embodiment will be explained.

(8) First, by turning on the power of the processing device 3, the processing unit 3 starts operating, and the data recorder 8 reproduces the contents (defective card number) stored on the tape, and stores the defective card in the RAM 28. Memorize the contents of the card and prepare for checking the credit card to be used. Even after this operation is completed, the processing device 3 cannot be operated. Unless this processing device 3 is allowed to be used only by certain designated persons, it is impossible to prevent unauthorized use of credit cards and crimes. For this reason, the master card 40 (
(the same shape as the magnetic card 1) is prepared to prevent unauthorized use of the processing device 3 by a third party. Pass the MasterCard 4o through the card reader 4, read the contents recorded on the MasterCard 4O, type in the operator's password using the 16 keyboard 11, and the password stored in the MasterCard 4o matches the password entered. Then this master card 4
If the master card 40 can be used by the holder of the master card 40, the master card code of the master card 40, the holder code, and the date and time are recorded in the data recorder 8 at the same time. Thereafter, the operator can select the function keyboard 7 and perform various processes. Note that if the passwords do not match after passing the master card 40 through the card reader 4, the buzzer 14 will sound to indicate an error.

The flow of the above-mentioned operation is the same as the flowchart shown in FIG.

Next, the procedure for each function will be explained in order.

``Issuance'' This processing device 3 has a function that allows the magnetic card 1 to be issued as a credit card. A MasterCard 40 must be used. By passing the master card 40 containing this privilege setting code through the card reader 4Vc, the privilege setting code is stored in the RAM 28. Then, when you enter the above-mentioned "Function mode", B pole if 6 (
1]) By pressing the button 21, the Master Card 40 will be
RAM2
8 and the letter contents stored in ROM1? It compares the programs in the program, and if you have privileges, you can use the "issue" routine. If you do not have MasterCard 40Vc privileges, a buzzer will sound, indicating that you are not eligible to use the card, and the transaction will be terminated.
The mode of publication becomes unavailable. When the privilege check is passed and the "issuance" mode becomes available with the privilege of the master card 40, the full keyboard 9'! il-operate to enter information regarding the issued credit card (magnetic card 1). First, when you enter your credit card PIN number, it is converted into a 4-digit, 2-byte hexadecimal number, and 1
1. It is temporarily stored in the AM2g, and at the same time, the message "Waiting for data input" appears on the cathode ray tube 6, and the full keyboard 9
It is now possible to enter personal data. Personal data includes name, address2 date of issue, expiry date, etc.
It is written to the DATA area with a length of bytes. DAT
A is (12) written as Japanese information mixed with kanji, hiragaga, katakana, English characters, etc. through kana-kanji conversion, etc., and both the password and DATA are first displayed on the cathode ray tube 6. The data is temporarily stored in the RAM 28. An example of a display by this cathode ray tube 6 is shown in FIG. In addition, the Japanese display on the cathode ray tube 6 is displayed on the instruction keyboard I.
It is possible to correct, delete, and move the cursor by pressing OK.

Next, the flow of inputting the Japanese information and displaying it on the cathode ray tube 6 will be explained with reference to FIG. When a Japanese word is entered on a full keyboard 9 arranged in a 50-syllable arrangement, the code is transmitted from the full keyboard 9 to an input conversion circuit 33 via an input control circuit 32. The input conversion circuit 33 operates in the same mode until a conversion mode instruction is received from the full keyboard 9, waits for a kanji conversion mode instruction, and transmits the input character code to the conversion dictionary file 34 to perform kana-kanji conversion. The converted kanji code is transmitted to the character generation circuit 35 via the input conversion circuit 33.

The character generation circuit 35 accesses the character pattern corresponding to the stored kanji code from the character pattern file 36 and outputs the character pattern to the arithmetic control circuit 15. If you enter a character code such as Gaga, Katakana, or English characters,
The arithmetic and control circuit 15 often displays this Japanese language, which is a mixture of kanji, hiragana, katakana, English letters, etc., on the screen of the cathode ray tube 6.

Further, the Japanese character code recorded on the magnetic stripe 2 of the magnetic card 1 is similarly read by the card reader 4 and sent to the input/output control circuit 3Q.

Kana-kanji conversion is performed in a conversion dictionary file 34 via an input/output conversion circuit 31, character patterns are selected in a character generation circuit 35, and can be displayed as they are on the cathode ray tube 6 via an arithmetic control circuit 15. In addition, full keyboard 9
The character information typed in is displayed on the cathode ray tube 6 as described above, but at the same time, the input/output conversion circuit 31. The information can be transmitted to the card reader 4 via the input/output control circuit 30, and the card reader 4 can write on the blank magnetic stripe 2.

When you have finished entering personal data using Full Keyboard 9, click
To complete data input, press the RETURN key to instruct the processing device 3 to perform the next operation. By pressing this ITU published N key, the processing device 3 arranges the data using an internal program, and the full keyboard 9 [in addition to the personal data from the IC, data from the master card 40, that is, the master card code (-operator ID) A unique number (machine ID) set in the processing device 3 is on standby for writing. Next, when the magnetic card 1 with a blank background (not written yet) is inserted into the card reader 4, the above-mentioned 8th
The personal information of the personal data shown in the figure and the management information such as Oberame ID, machine ID, issue date and time are on the magnetic stripe 2V.
C number is placed. However, even if it is written once, it is not possible to determine whether the contents have been correctly written into the VC@, so the magnetic card 1 is inserted into the card reader 4Vc again, and the contents stored in the processing device 3 and the magnetic card 1 are read. Compare and check the contents (verify). If the writing is correct in this check, the card issuing mode ends, and if the writing is incorrect, a buzzer sounds to indicate an error and instruct the user to write again. Further, the same personal data information and management information as written on the magnetic card 1 are stored in the data recorder 8 at the same time. The procedure for this operation is shown in the flowchart in FIG.

``Read'' You can record the sales date, time, amount, etc. of a product using the issued credit card. First, as described above, when the operator's password matches through the master card 40, the user presses the function mode Kfz, read 1' button 322 to move to the reading mode. In this case, the credit card is passed through the insertion groove 5 of the card reader 4 to read the information, and if the password operated by the card holder matches the password code in the card information, the sale is allowed. At this time,
The card information shown in FIG. 8 is displayed in Japanese on the screen of the cathode ray tube 6, making it easier to recognize whether or not the cardholder is the owner of the card. Start. This credit card can be used for cash register work at a members-only restaurant, for example, and the operating procedure in this case is as follows.
