2. Description of the Related Art In order to eliminate the complexity of change transfer between a purchaser and a seller, the change amount is recorded in a memory card, and when the accumulated amount of change amount reaches a predetermined amount, it is the same as a prepaid card. Japanese Patent Laid-Open No. 4-3296 discloses a fee recording system configured so that the card has a fee payment function.

In this system, an addition status code is recorded in advance in a card in the initial state, and a subtraction status code is recorded when the accumulated change amount reaches a predetermined amount. The status code is used to determine whether the item is in the change accumulation state or the prepaid card state.

[0004]

That is, in the above-mentioned conventional system, the status of the card is determined by the status code corresponding to each status. Accordingly, the recording area for the status code has to be additionally set, which makes it less flexible.

On the other hand, the present inventor has paid attention to the issue date data recorded on this type of card in order to grasp the expiration date and the target amount achievement period.

In view of the inconvenience of such a conventional fee recording system and the knowledge of the present inventor, the main object of the present invention is to:
It is an object of the present invention to provide a fee recording method configured so that the state of a card (change accumulation / prepaid) can be discriminated without requiring setting of a special data area.

[0007]

According to the present invention, such a purpose is to use a storage card having at least a storage area for remaining amount data and issue date data, and perform an addition process until a predetermined amount is reached. Is a fee recording method in which the accumulated amount data of is recorded, and after reaching the predetermined amount, the purchase amount is subtracted as a prepaid card and the remaining amount data is recorded. Adding or subtracting a predetermined value to the issue date data,
A fee recording method, characterized in that whether to add change or subtract purchase amount to the balance data of the card is determined by whether or not the issue date data is processed. To be achieved.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The structure of the present invention will be described in detail below with reference to specific embodiments shown in the accompanying drawings. FIG. 1 is a system configuration diagram of a change recording apparatus to which the present invention is applied. This system comprises a POS register 1, a card reader / writer 3 for reading and writing a storage card 2 such as a magnetic card or an IC card, counting computers 4a and 4b, and a host computer 5.

The basic hardware configuration of the POS register 1 and the card reader / writer 3 is a storage / calculation device 6/7 containing a microcomputer, and keyboards 8/9 for inputting amount data and data necessary for processing. The display 10 and 11 display the amount of money and the processing status.

The POS register 1 and the card reader / writer 3 each have an individual computer 4 for counting.
a. 4b are connected, and the accumulated data can be collectively processed with the host computer 5 connected to the counting computers 4a, 4b via the communication circuit 12. ing.

POS register 1 and card reader / writer 3
Are connected to each other via a dedicated communication cable 13, and exchange of data necessary for exchanging charges such as purchase amount, deposit amount, and change between the POS register 1 and the card reader / writer 3. It is like this.

The POS register 1 and the card reader
It is not always necessary to connect to the writer 3 with the dedicated communication cable 13, and the object of the present invention can be achieved even if the card reader / writer 3 is independent, for example. In this case,
It is necessary to individually input the required amount of money between the POS register 1 and the card reader / writer 3. Further, the addition / subtraction tabulation process relating to each amount data can be verified by, for example, equipping each device with a printer or the like.

The card reader / writer 3 reads each data recorded in the magnetic recording area of the storage card 2 inserted from the insertion slot 14, sends the read data to the POS register 1, and sends it from the POS register 1. Various data including the balance data to be written is written.

Next, the processing procedure of the present invention will be described with reference to FIG.

When it is detected that the storage card 2 is inserted into the card reader / writer 3 (step 1), each data in the magnetic recording area is read (step 2), and it is first determined whether the issue date is within the expiration date. Determine (step 3). Note that the date data is, for example, 1 January 1993, 9
It is represented by a 6-digit (16-bit) number such as 30101 or by a 5-digit cumulative number of days starting from January 1, 1900, for example. To do.

As a result, if it is outside the expiration date, the card is discharged as invalid (step 4), and if it is within the expiration date, it is judged whether or not the last two digits of the issue date data are 31 or less (step 5). ). Here, since one month has a maximum of 31 days, if the last two digits of the issue date data are in the range of 1 to 31, it can be determined that the date data is not processed. Therefore, if the last two digits of the issue date data are 31 or less, it is determined that the change is being accumulated and the following addition processing is performed.

In the addition process, first, the added amount C corresponding to the change amount input at that time from the POS register is added to the accumulated change amount Ct, and the updated value of the accumulated change amount Ct is temporarily stored. (Step 6). Next, this accumulated change amount Ct is compared with a preset target amount M (step 7). If the accumulated change amount Ct is less than the target amount M, the accumulated change amount Ct of the memory card 2 is updated (step 8) Then, the storage card 2 is ejected (step 4).

As a result of adding the change amount this time, the accumulated change amount Ct
If the target amount M exceeds the target amount M, this is set as the prepaid initial amount Ct (step 9), and the lower 2 of the date data is set.
After adding a predetermined value (for example, 31) to the digit (step 10), the card is ejected (step 4).

On the other hand, when the last two digits of the issue date data confirmed in step 5 is 32 or more, it is determined that the storage card 2 is already in the prepaid card state, and the following subtraction processing is performed.

In the subtraction processing, first, the purchase amount A at that time input from the POS register is subtracted from the remaining amount Ct of the prepaid card generated in the preprocessing to obtain the remaining amount Ct.
Is updated (step 11). Next, the balance Ct is determined (step 12), and when the balance Ct this time is determined to be zero, the valid years are subtracted from the first two digits of the date data and the card is invalidated (step 13). The card is ejected (step 4), and if there is a balance Ct, this balance is recorded in the storage card 2 (step 8) and the card is ejected (step 4).

Since the processed date is always 32 or more, it is possible to easily confirm the original issue date by subtracting the above predetermined value (31) from the last two digits of the date data. . In addition, when expressing the date with the cumulative number of days, it is sufficient to subtract or add an appropriate number set to a value that is not possible in practical use to the original number, in short, to process the original number. It is sufficient to select a value that can be reliably determined and that can be easily restored to the original value.

[0023]

As described above, according to the present invention, it is possible to set a special code or recording area by adding or subtracting a predetermined numerical value set in advance corresponding to the state of a card to date data. Since the state of the card can be determined without using the magnetic data area, it is possible to effectively use the magnetic data area and to provide expandability.
