Abstract

PURPOSE:To improve the memory efficiency by providing a flag on emergency notice data and discriminating the emergency notice data before and after generating an optical card, and erasing only overlapped emergency notice data after supplying the optical card. CONSTITUTION:Check data is divided into an accident card list 35 recorded in a storage medium and supplied periodically, and emergency notice data 41 of an accident card generated irregularly. Also, a flag is provided on the emergency notice data 41, and at the time of an emergency notice, if it is before a recording medium is generated, check data is informed to a card check system without setting a flag. On the other hand, if it is after the recording medium is generated, and before it is supplied to the card check system, the flag is set and the check data is informed to the card check system, the recording medium is replaced, and the check data in the which the flag is not set is erased from a memory. In such a way, the defect is avoided that the check data is overlapped partially and the memory efficiency is deteriorated after an optical recording medium, etc., are delivered.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides check data that is applied to a card check system that checks card-like recording media such as magnetic cards, optical cards, and IC cards used in credit cards. Regarding notification method.

[Prior Art] In recent years, credit cards and the like have been widely used when purchasing products. When a credit card or the like is used, the seller checks whether there are any problems with the credit card or the like.

In such cases, the checking method used was to turn over a checklist containing data related to the card involved in the accident, or to make an inquiry to the host computer at the center based on the credit card number 10.

However, all of the above-mentioned checking methods have a problem in that they are time-consuming and cannot be checked quickly. Furthermore, the method of flipping over the checklist has the disadvantage that the checklist must be rewritten every time an accident card is notified. For this reason, a card check system has been proposed in which check data is recorded in a large-capacity storage unit, such as an optical recording medium, and the card-shaped recording medium is checked.

Incidentally, the optical recording medium and the like on which the above-mentioned check data is recorded are produced by card companies that handle Fresi-2 cards, and are periodically supplied to stores equipped with card check systems. Furthermore, when an accident card occurs while creating an optical recording medium or the like, check data of the accident card is notified by means such as communication. At that time, the check data based on the emergency notification is stored in the memory within the card check system. Moreover, the emergency notification data is recorded on the optical recording medium supplied next time.

[Problems to be Solved by the Invention] As described above, when recording check data on an optical recording medium etc. and supplying it periodically and notifying the check data of accident cards that occur irregularly by communication etc., optical recording After the delivery of the medium, etc., some of the check data is duplicated, which has the disadvantage of poor memory efficiency.

On the other hand, if check data is deleted from the memory in the card check system after delivery of optical recording media, etc. in order to increase memory efficiency, emergency notifications of accident cards that occurred after the optical recording media, etc. were created will also be deleted. Therefore, there is a risk that damage may occur due to the accident card corresponding to the erased check data.

[Means for Solving the Problems] In order to solve the above-mentioned conventional problems, the present invention has the following steps:
In the card check system for checking the card-shaped recording medium, the check data is divided into an accident card list recorded on the recording medium and supplied periodically, and emergency notification data of accident cards that occur irregularly,
A flag is set in the emergency notification data, and when an emergency notification is made, the check data is notified to the card check system without setting the flag if the recording medium is not created, and the card check is performed after the recording medium is created. If the recording medium is not supplied to the system, the flag is set and the check data is notified to the card check system, and after the recording medium is supplied, the recording medium set in the card check system is replaced, and the card check system The check data for which the flag is not set is erased from the memory.

[Example] Hereinafter, an example of the present invention will be described in detail with reference to the drawings.

FIG. 5 is a block diagram of a card check system to which the check data notification method of the present invention is applied. First, an overview of this card check system will be described.

In the figure, the card check system includes a magnetic card reader 31 and an optical card reader 32 that read predetermined data recorded on a magnetic card and an optical card, which are card-like recording media used in credit cards, as a card reading unit, and an optical card reader 32 for checking. An optical card reader 40, an EEPROM 41, and a ROM 42 are used as a data storage section, a microcomputer (CPU) 50 and an internal memory 51 are used as a judgment section, an LCD (liquid crystal display) 60 and a printer 61 are used as an output section, and a numeric keyboard is used as an input section. 70 and
The communication device 80 is configured to include a communication device 80.

The above-mentioned optical card reader 40 has one of magnetic cards and optical cards.
An optical card 35 on which card information such as 0 No. and the details of the accident on the card is written is used as a check data recording medium, and a magnetic card reader 3 is used from this optical card 35.
1. Card information corresponding to the magnetic card or optical card read by the optical card reader 32 is read. EEPROM4 above
1 is for writing data when there is an emergency notification etc. related to a credit card accident card. The ROM 42 stores programs for judgment and control by the microcomputer 50.

The internal memory 51 stores card information read by the optical card reader 40.

In the microcomputer 50, the Si magnetic card reader 31 searches the internal memory 51 for the check data of the credit card read by the optical card reader 32, and determines whether the credit card is good or bad. Controls the card reader 40 and the like.

Note that although the above explanation has been about checking credit cards, it goes without saying that the invention can be applied to other cards as well. Further, the card-shaped recording medium is not limited to a magnetic or optical card, but may also be an IC card or the like. Although the optical card reader 40 is used as the storage unit, a CD-ROM, DAT league, floppy disk, etc. may also be used.

Here, a check data notification method applied to the above-described card check system will be explained.

In the check data notification system of this embodiment, as shown in FIG. You will be notified of the accident card list containing the check data. It should be noted that the emergency notification data 3 is sent by communication or the like at any time, and the accident card list is written to the optical card 35 periodically (for example, every month) and notified.

FIG. 2 shows the structure of the emergency notification data 3.

As shown in the figure, the emergency notification data 3 consists of a flag 4, and check data 5 including the ID number of the accident card, the details of the accident, and the like. The flag 4 indicates whether the notification timing of the emergency notification data 3 is before or after the creation of the optical card 35, and in this embodiment, the flag 4 is set for the emergency notification data 3 after the creation of the optical card.

Next, the functions of the card check system 2 according to this embodiment will be explained with reference to FIG.

The microcomputer 50 included in the card check system 2 includes a comparison unit 52 that compares the credit card data read by the 8i card reader 31 or the optical card reader 32 with the check data of the optical card reader 40 or the EEPROM 41, and the optical card reader 40. an optical card replacement determining unit 53 that recognizes that the optical card 35 installed in the optical card 35 has been replaced; a flag determining unit 54 that determines whether the flag 4 of the emergency notification data 3 stored in the EEPROM 41 is set; EEF according to the judgment of the discriminator 54
It has an erasing section 55 that erases only the emergency notification data 3 for which the flag 4 is not set from the ROM 4.1. As a result, the new optical card 35 is delivered and the old optical card 35 is delivered.
When the optical card 3 is replaced with the optical card 3, the optical card replacement determination unit 53
Recognize the update of 5. In addition, record the O version number or production date on the optical card 35.
When replacing the optical card 35, it is possible to determine whether the optical card 35 is new or old by reading the version number and the like in the optical card replacement determining section 53.

When the update of the optical card 35 is recognized, the flag determining section 54 checks the flag 4 of the emergency notification data 3, and the erasing section 55 erases the emergency notification data 3 for which the flag 4 is not set.

Next, the operation of this embodiment will be explained according to the time chart of FIG. 4.

In this embodiment, when making an emergency notification before creating the optical card 35, the notification is made without setting the flag 4 of the emergency notification data 3. This is referred to as emergency notification data 3a. When issuing an emergency notification after creating the optical card 35 and before replacing it with the old optical card 35 in the card checking system 2,
Flag 4 of emergency notification data 3 is set to notify. This is referred to as emergency notification data 3b. When making an emergency notification after updating the optical card 35, the notification is made without setting the flag 4 again. This is referred to as emergency notification data 3C.

The emergency notification data 3a is sent as an emergency notification, and is also written to the optical card 35 as additional data to the accident card list and supplied to the card check system 2. On the other hand, the emergency notification data 3b is not written to the optical card 35.

As a result of the above emergency notification, when the optical card 35 is supplied, the EEFROM 41 of the card check system 2 has the following information:
Emergency notification data 3a and emergency notification data 3b are stored. Further, the accident card list of the supplied optical card 35 includes emergency notification data 3a.

After the optical card 35 is supplied, the optical card 35 of the card check system 2 is replaced with the supplied new optical card 35. As a result, the optical card replacement determining section 53 recognizes the update of the optical card 35, and the flag determining section 54 recognizes that the optical card 35 has been updated.
It is determined whether each piece of data stored in 41 is emergency notification data 3a or emergency notification data 3b. Then, the erasing unit 55 erases the emergency notification data 3a that overlaps with the accident card list of Koryoku-135 from the EEPROM 41. Therefore, the accident card list and the emergency notification data 3b constitute check data for all accident cards.

After the optical card 35 is supplied, emergency notification data 3C is notified.
It will be added to the check data of all accident cards mentioned above. In addition, the emergency notification data 3C is stored on the optical card 35 that will be created next.
written to.

In addition, in the above procedure, the emergency notification data 3b will be accumulated in the EEFROM 41, but the emergency notification data 3b will be stored in the EEFROM 41.
b may be written on the optical card 35 to be created next and erased after the optical card 35 is delivered. In this case, it is possible to distinguish between the old emergency notification data 3b and the new emergency notification data 3b by providing another flag or the like in the emergency notification data 3b after the creation of the optical card 35.

[Effects of the Invention] As explained above, the check data notification method of the present invention sets a flag in the emergency notification data to distinguish between the emergency notification data before and after the creation of the optical card, and only the emergency notification data that overlaps after the optical card is supplied is removed. Since the data is erased, memory efficiency is greatly improved.

Further, since the emergency notification data after the optical card is created remains without being deleted, there is an effect that the credit card can be checked using the check data of all accident cards including the latest accident card.
