Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to the sale of goods such as an electronic cash register and a POS (Point of Sale Information) system in which this electronic cash register is centrally managed by a host controller. The present invention relates to a data processing device, and more particularly to a device in which a fractional amount generated in payment of a purchase price is settled by a card.

[Prior Art] Conventionally, a method of adjusting a fractional amount generated in payment of a shopping price by a card capable of storing information is disclosed in, for example,
As can be seen in JP-A-63-249293, a method of accumulating and recording a fractional amount of change when a customer pays for the price, and a method of storing a card in which a customer has a predetermined limit. Two methods have been considered, in which a purchase is made at or near the limit, and when a fractional amount occurs at the time of payment, the fraction is subtracted from the limit of the card and the remaining amount is recorded.

However, in the former method, if the accumulated amount of the card reaches a certain amount, it must be operated in such a way that cash is refunded or exchanged for a certain product in exchange for the card. On the other hand, even in the latter method, when the card balance becomes 0 yen or less, the card cannot be used.

[Problems to be Solved by the Invention] As described above, according to the conventional technology, not only when the card is lost or damaged, but also when the accumulated amount of the card reaches a certain amount, or the remaining amount with respect to the limit is 0 yen or less. If the card becomes, the card cannot be used and another card must be issued. For this reason, a large number of cards were required to operate the system, and high costs were unavoidable.

If the card is lost or damaged, another card will be issued, but the balance of the old card is not guaranteed because it is recorded only on that card. For this reason, if the card is lost or damaged, the customer will be hurt and the service is poor.

Therefore, the present invention provides a product sales data that can increase the usage rate of a card without loss of the card, which can eliminate the need for delivery of a fractional amount generated in the payment of the shopping price, without loss of the customer. It is intended to provide a processing device.

[Means for Solving the Problems] A first invention of the present application is directed to a card reader / writer that reads and writes information on a card capable of storing information such as a card number and balance data, and a total amount calculated by the totaling means. Fraction amount extracting means for extracting a fractional amount of money, payment amount displaying means for displaying on a display a total amount excluding the fractional amount extracted by the extracting means, and extracting means from a card balance read by a card reader / writer. The card balance reduction means for reducing the fractional amount extracted by the above and writing the value as balance data to the card, a deposit key for inputting the amount data of the advance receipt, and when the amount data of the advance receipt is inputted by this deposit key, , Add the amount data of the balance advance receipt of the card read by the card reader / writer and write the value as balance data on the card. A card balance increasing means, a card management file for recording the increased / decreased card balance in association with the card number of the card each time the card balance is increased / decreased by the card balance increasing / decreasing means, When an update key instructing an update from a card to a new card and an update from an old card to a new card are issued by inputting the update key, the latest card balance corresponding to the card number of the old card is obtained from the card management file. And a card updating means for reading the new card and writing the new card into a new card mounted on the card reader / writer.

The second invention of the present application is a card reader / writer that reads and writes information from / to a card that can store information such as a card number and balance data, and a card reader / writer that reads the total amount calculated by the totaling means using the card reader / writer. Calculating means for adding the balance, fractional amount extracting means for extracting a fractional amount of the added amount calculated by the calculating means, and payment amount for displaying on the display the added amount excluding the fractional amount extracted by the extracting means Display means, card balance updating means for writing the fractional amount extracted by the extracting means on the card as a card balance read by a card reader / writer, a clock circuit for storing the present date, and the individual of each card owner Card management that records the card number, card balance, and last date of handling of the card owned by the card holder in accordance with the information Each time the card balance is updated by the file and the card balance updating means, the card balance of the card recorded in the card management file is changed to the updated balance, and the last handling date is changed to date data read from the clock circuit. And a final date setting means for setting the date.

[Operation] In the first invention of the present application, when a card presented by a customer is attached to a card reader / writer and sales registration of a product written by the customer is performed, the total amount of the customer is calculated, Further, a fractional amount of the total amount is extracted. Then, the fractional amount is reduced from the card balance of the customer, and the customer pays the amount obtained by subtracting the fractional amount from the total amount. On the other hand, if you operate the input key with the card mounted on the card reader / writer and enter the amount of the advance receipt,
The input amount is added to the card balance of the card. Therefore, when the card balance becomes low, the card balance can be increased by paying the advance payment. Also,
When the update key is operated with the card loaded in the card reader / writer to instruct the card to be updated from the old card to the new card, the latest card balance corresponding to the card number of the old card is read from the card management file, and the card is read. Written on the new card attached to the writer. Therefore, even if the card is lost or damaged, the balance of the lost or damaged card is transferred to a new card and used continuously, so that the balance of the card paid in advance by the customer is guaranteed, Customers do not hurt.

According to the second aspect of the present invention, when the card presented by the customer is attached to the card reader / writer and the sales registration of the product written by the customer is performed, the total amount of the customer is calculated, and the total amount of the customer is further calculated. The balance of the card is added.
Then, a fractional amount of the added amount is extracted, and the fractional amount is written on the card as a card balance. On the other hand, the customer pays an amount obtained by subtracting the fractional amount from the above added amount. Therefore, the fractional amount is carried over to the next shopping as the card balance and paid at the next shopping, so that only a fractional amount less than a certain unit is always recorded on the card.
For this reason, even if the customer loses or damages the card, the customer does not lose and the damage to the store is small. Further, since the latest card balance and the handling date are recorded in the card management file corresponding to the card number of each card, it is possible to easily find a card that has not been used for a long time from the contents of the card management file. .

Then, when the card flag F1 is set, it is determined whether or not numerical data is stored in the number buffer 74. Then, if numerical data other than 0 is stored, the numerical data is compared with the cashier number in the cashier number memory 73.
Here, if they match, the prepaid deposit inquiry message is edited based on the card data in the card buffer 75 and the prepaid amount data in the work memory 76, and sent to the store processor 2 via the inline line 3. Ask. When the ACK response is returned from the store processor 2 in response, the contents of the card buffer 75 are updated by using the balance data included in the response message as the card balance, and
The contents of 75 are transmitted to the card reader / writer 4 via the card reader / writer control circuit 36 and written into the card (card balance increasing means). Further, the print data for deposit receipt is edited from the card number, name and card balance in the card buffer 75, the advance receipt amount in the work memory 76, and the balance data in the balance memory 80, and output to the printer drive circuit 44. ,
The receipt R1 for deposit receipt shown in FIG. 12 is printed and issued.
Thereafter, the card flag F1 and the depositing flag F3 are reset, and the process ends.

On the other hand, if a NAK response is returned from the store processor 2 in response to the deposit receipt inquiry, there is an error in the card data or the deposit amount data in the inquiry message, an error is displayed on the display 41, and This processing ends.

If the card flag F1 is reset to “0” in response to the input of the sign key 58 or if no numerical data is stored, the key operation of the sign key 58 is regarded as an error. Also, when the numerical data does not match the casher number, the key operation of the sign key 58 is regarded as an error.

In addition, the CPU 31 of each POS terminal 1 has a mode switch
When the "registration" mode is selected by 37, the program is configured to execute the card update process shown in FIG. 9 by key input of the update key 60. That is, when the update key 60 is fetched with key data via the keyboard circuit 40, the process is started, and after confirming that the customer has not registered for sale the purchased item, the updating flag F4 is set to "1". In this state, wait for the next car input. When the key operation of the card key 61 is detected, the card flag F1 is set, and the card data read by the card reader / writer 4 via the card reader / writer control circuit 36 is written into the card buffer 75. Wait for key input.

Also, while the updating flag F4 is set,
When it detects that the key 51 has been operated, it waits for the input of 13-digit numerical data. Then, when 13-digit numerical data is input, the numerical data is transferred to the work memory 76 as the card number of the old card, and waits for the next key input.

On the other hand, if it is detected that the sign key 58 has been operated with the updating flag F4 set, the card flag
Check the state of F1. Then, when the card flag F1 is set, it is determined whether or not numerical data is stored in the number buffer 74. Then, if numerical data other than 0 is stored, the numerical data is compared with the cashier number in the cashier number memory 73. Here, if they match, the card update inquiry message is edited based on the card data in the card buffer 75 and the old card number data in the work memory 76, and the store processor 2 Contact If an ACK response is returned from the store processor 2 in response, the contents of the card buffer 75 are updated using the balance data contained in the response message as the card balance, and the contents of the card buffer 75 are used as a card reader / controller control circuit. The data is transmitted to the card reader / writer 4 via 36 and written on the card (card updating means). Further, the card update print data is edited from the card number (new card number), name and card balance (write amount) in the card buffer 75, and the old card number in the work memory 76, and sent to the printer drive circuit 44. It outputs and prints and issues a card update receipt R2 shown in FIG. After that, the card flag F1 and the updating flag F4
Is reset, and this process ends.

On the other hand, if a NAK response is returned from the store processor 2 in response to the card update inquiry, there is an error in the card data or the old card number data in the inquiry message, and an error is displayed on the display 41. Then, this process is terminated.

If the card flag F1 is reset to “0” in response to the input of the sign key 58 or if no numerical data is stored, the key operation of the sign key 58 is regarded as an error. Also, when the numerical data does not match the casher number, the key operation of the sign key 58 is regarded as an error.

The CPU 31 of each POS terminal 1 has a mode switch 37
In the state in which the “registration” mode is selected, the program is controlled to execute the sales processing shown in FIG. 10 by inputting a predetermined key. That is, when the key data of the card key 61 is fetched via the keyboard circuit 40, the card flag F1 is set, and the card data read by the card reader / writer 4 via the card reader / writer control circuit 36 is transferred to the card buffer 75. Write to. Further, the balance of the card in the card data is written into the balance memory 80, and the next key input is awaited.

On the other hand, when the key data of the section key 53 is fetched via the keyboard circuit 40, the registering flag F2 is set, and the sales data of the section registered product is stored in the section registration memory.
Cumulative processing is performed at 71. Further, the sales amount is added to the customer totalizer 72. Further, the section code and the sales amount are displayed on the display 41, and the printer 43 is driven to print the receipt on the receipt, and waits for the next key input.

When the key data of the subtotal key 54 is fetched via the keyboard circuit 40, it is confirmed that the registering flag F2 is set. Thereafter, the state of the card flag F1 is checked.
When the card flag F1 is reset, the customer does not perform the processing for the fractional amount of the purchase price by the card, so that the ordinary subtotal key processing and the normal key processing are executed.

When the card flag F1 is set, first, the total amount in the customer totalizer 72 is divided by the fractional unit in the fractional unit memory 79, and the remainder is set as the fractional amount in the fractional amount memory 78.
(Fraction amount extracting means). Next, the above-mentioned fractional amount is subtracted from the balance data in the balance memory 80, and the difference is stored again in the balance memory 80 (card balance reduction means). However, at this time, if the balance data in the balance memory 80 is negative, it is impossible to process the fractional amount of the purchase price by the card, so that the processing shifts to the normal subtotal key processing and the closing key processing.

If the balance data in the balance memory 80 is 0 or more, the fractional amount in the fractional amount memory 78 is subtracted from the total amount in the customer totalizer 72, and the difference is used as the payment amount.
To be stored. Then, the payment amount is displayed on the display 41. (Payment amount display means). Further, the printer 43 is driven to print the total amount, the fractional amount and the payment amount on the receipt.

Thereafter, the key input of the deposit / current total key 55 is waited. And
When the deposit / current total key 55 is input and the transaction closing by cash settlement is instructed, the change amount is calculated by subtracting the payment amount from the deposit amount, and the change is displayed on the display 41. Note that the deposit amount is the numerical value data if numerical data was input by the numeric key 51 immediately before the key input of the deposit / current total key 55, and if not, it is the contents of the payment amount memory 77. Next, the printer 43 is driven to print the deposit amount, change, and balance data in the balance memory 80 on a receipt, and issues a customer receipt R3 shown in FIG. If the balance data is less than the unit price in the fractional unit memory 79, a predetermined message is printed as shown in FIG. 15, and then a receipt R4 is issued. At the same time drawer 45
Release. After updating the card balance of the card buffer 75 to the balance data in the balance memory 80 and updating the last handling date to the current date stored in the clock circuit 34, the contents of the card buffer 75 are updated. The data is transmitted to the card reader / writer 4 via the card reader / writer control circuit 36 and written into the card. Thereafter, the contents of the card buffer 75 are incorporated into the sales information message and transmitted to the store processor 2 via the inline line 3, and the process is terminated.

On the other hand, the CPU 11 of the store processor 2 is configured to execute a process shown in FIG. 11 when a message is input from each POS terminal 1 via the in-line line 3. That is, when receiving the deposit receipt inquiry message from each POS terminal 1, after confirming that the advance receipt amount data in the message is greater than 0 yen, the card management file is entered using the card number included in the card data in the message. The card number area B1 of No. 5 is searched. If a card number corresponding to the area B1 has been set, the advance amount in the message is added to and updated in the contents of the advance amount area B3 and the balance area B5 corresponding to the card number. Thereafter, the balance data in the balance area B5 is incorporated into the ACK response message, and the POS terminal 1 is inquired about, and the process is terminated.

If the advance payment amount in the message is 0 yen or less, or if the corresponding card number is not set in the card number area B1 of the card management file 5, a NAK response is sent to the inquired POS terminal 1. Reply and end this process.

When the card update inquiry message is received from each POS terminal 1, after confirming that the message includes the old and new card numbers, the card number area B1 of the card management file 5 is searched with these new and old card numbers. . And
If both card numbers corresponding to the above area B1 have been set, the advance payment area corresponding to the old card number
The contents of B3, the final date area of handling B4 and the balance area B5 are moved to the same area corresponding to the new card number, and one record of the old card number is deleted. Thereafter, the balance data in the balance area B5 corresponding to the new card number is incorporated into the ACK response message and returned to the inquired POS terminal 1, and the process is terminated.

If at least one of the new and old card numbers does not exist in the message, or if the card number corresponding to the card number area B1 of the card management file 5 is not set, a NAK is sent to the inquired POS terminal 1. A response is returned, and the process ends.

When the sales information message is received from each POS terminal 1,
It is determined whether or not card data exists in the message. If it exists, the card number included in the card data is used as the card number area B1 of the card management file 5.
And changes the contents of the balance area B5 corresponding to the card number to the balance data in the card data. Further, the content of the last handling date area B4 corresponding to the card number is changed to the current date stored in the clock circuit 34. Thereafter, various files in the disk memory 15 are updated based on the sales information in the message, and the process ends. If no card data is included in the message, the sales update process is immediately performed, and the process ends.

In the present embodiment configured as above, the store issues a card in which the card number and the like of the customer who wants to use the card are recorded in advance, and operates the keyboard 22 of the store processor 2 to perform card management. The card number, name and address corresponding to file 5 are set. The customer who receives the card gives the clerk the card and an appropriate deposit. The clerk first presses the deposit key 59 of the POS terminal 1. Next, the card is mounted on the card reader / writer 4 and the card key 61 is pressed. Then, the card buffer 75
Stores the card data of the card. At this time, the content of the balance memory 80 is “0”. Next, the clerk enters the amount of the advance receipt and presses the amount key 52. Then, the advance receipt amount is stored in the work memory 76. Next, the clerk enters his own cashier number and presses the sign key 58. Then, the deposit receipt inquiry message is transmitted to the store processor 2, and the deposit amount is stored in the deposit amount area B3 and the balance area B5 corresponding to the corresponding card number in the card management file 5. The card reader / writer 4 stores the advance payment amount in the balance area A2 of the card.
Thus, the customer can use the card to pay and process a fraction of the shopping price.

That is, the customer hands the card along with the purchased product to the clerk. First, the clerk inserts the card into the card reader / writer 4 and presses the card key 61, and then operates the section key 53 and the like to execute the registration processing of the product for sale. Then, when all the products have been registered, the subtotal key 54 is pressed. Then, the customer totalizer 72 is added to the fractional unit of the fractional unit memory 79.
Is calculated, and the fractional amount is subtracted from the card balance of the card. Here, assuming that the fraction unit is [10 yen] and the total amount of the customer is [10103 yen], the fraction amount [3 yen] is obtained. If the card balance before the update is [10000 yen], the card balance is [9997]
Yen]. Then, the customer's payment amount [10000 yen (10103-3)] is displayed on the display, and the total amount, fractional amount and payment amount are printed on the receipt. Thereafter, when the clerk receives the cash corresponding to the payment amount from the customer, the clerk presses the deposit / current total key 55 to close the transaction. As a result, a customer receipt R3 as shown in FIG. 14 is issued. In addition, the contents of the remaining area A2 of the card are updated to the balance after the fractional amount has been reduced, and the final handling date area
The current date is recorded in A3 and the card is returned to the customer.
In addition, the contents of the balance area B5 corresponding to the card number in the card management file 5 are similarly updated, and the last handling date is changed to the current date.

In this way, when the customer makes a purchase and a fraction of a fraction is generated for the price, the fractional amount is reduced from the card balance of the card. Therefore, coins less than a fractional unit are not used for giving and receiving money for payment.

Then, when the card balance becomes less than a fractional unit, a message prompting the addition of the advance receipt is printed on the customer receipt issued at that time as shown in FIG. The customer then hands the clerk an additional down payment with the card. On the other hand, the clerk operates the terminal 1 in the same manner as when issuing a card. Then, the advance amount added to the previous card balance of the card is added to increase the card balance. Accordingly, the card balance can be increased by adding an advance payment each time the card balance is reduced, so that one card can be used for a long time as long as the card is not lost or damaged.

Further, since the last date of handling of the card user by the card management file 5 is also managed, by checking the file 5, it becomes possible to grasp the usage situation of the card user accurately.

On the other hand, when a customer replaces a lost or damaged card with a new card, the clerk first operates the POS terminal 1.
Of the update key 60 is pressed. Next, the new card already issued to the customer is mounted on the card reader / writer 4 and the card key 61 is pressed. Then, the card number and the like of the new card are stored in the cart buffer 75. Next, the clerk operates the number key 51 to enter the card number (13 digits) of the customer's old card. Then, the work memory 76
Stores the card number of the old card. Next, the clerk enters his own cashier number and presses the sign key 58. Then, the card update inquiry message is transmitted to the store processor 2, and the old card number of the file 5 is stored in the advance receipt area B3, the last handling date area R4 and the balance area B5 corresponding to the new card number of the card management file 5. The contents of the corresponding area are moved. Further, the contents of the balance area B5 corresponding to the new card number are returned to the POS terminal 1, written on the new card as balance data of the new card, and used for the subsequent payment of the fractional purchase price. Therefore, the balance of the old card, which has become unusable due to loss or damage, is reliably guaranteed as the balance of the new card. It can measure.

Next, an embodiment in which the second invention of the present application is applied to the POS system shown in FIG. 1 will be described with reference to the drawings.
The memory format of the card used in this embodiment is the same as that of the first embodiment of the present invention.
The description is omitted with reference to the drawings. Also, since the schematic configurations of each POS terminal 1 and store processor 2 are the same as those of the first embodiment of the present invention, FIGS.
The description is omitted with reference to the drawings. However, in the second invention of the present application, since it is not necessary to input the amount of the advance payment in advance,
Deposit key 59 of keyboard 39 in each POS terminal 1
The deposit flag F3 of the RAM 33 can be omitted. A card management file 5 provided in the store processor 2
As shown in FIG. 16, the advance receipt area of the card management file (FIG. 3) in the embodiment of the first invention of the present application is shown in FIG.
B3 is omitted.

Then, when the update key 60 is operated by key input operation in the state where the "registration" mode is selected by the mode switch 37, the CPU 31 of each POS terminal 1 performs the ninth operation in the same manner as in the first embodiment of the present invention. The program is configured to execute the card update processing shown in the figure.

That is, when the key data of the card key 61 is fetched via the keyboard circuit 40, the card flag F1 is set, and the card data read by the card reader / writer 4 via the card reader / writer control circuit 36 is stored in the card buffer 75. Write. The card balance in the card data is stored in the memory 80.
And wait for the next key input.

On the other hand, when the key data of the section key 53 is fetched via the keyboard circuit 40, the registering flag F2 is set, and the sales data of the section registered product is stored in the section registration memory.
Cumulative processing is performed at 71. Further, the sales amount is added to the customer totalizer 72. Further, the section code and the sales amount are displayed on the display 41, and the printer 43 is driven to print the receipt on the receipt, and waits for the next key input.

When the key data of the subtotal key 54 is fetched via the keyboard circuit 40, it is confirmed that the registering flag F2 is set. Thereafter, the state of the card flag F1 is checked.
When the card flag F1 is reset, the customer does not perform the processing for the fractional amount of the purchase price by the card, so that the ordinary subtotal key processing and the normal key processing are executed.

When the card flag F1 is set, first, the card balance in the balance memory 80 is added to the total amount in the customer totalizer 72, and the added amount is stored in the work memory 76 (operation means). Next, the additional amount in the work memory 76 is divided by the fractional unit in the fractional unit memory 79, and the remainder is stored in the fractional amount memory 78 as a fractional amount (fraction amount extracting means). Next, the fraction amount in the fraction amount memory 78 is subtracted from the added amount in the work memory 76, and the difference is stored in the payment amount memory 77 as the payment amount. Then, the payment amount is displayed on the display 41 (payment amount display means). Further, the printer 43 is driven to calculate the total amount,
Have the card balance and payment amount printed on the receipt.

Thereafter, the key input of the deposit / current total key 55 is waited. And
When the deposit / current total key 55 is input and the transaction closing by cash settlement is instructed, a change operation is performed and the change is displayed on the display 41. Next, the printer 43 is driven to print the deposit amount and the change on the receipt. Further, a fractional amount in the fractional amount memory 78 is printed on the receipt together with a predetermined message as a card writing amount, and a customer receipt R5 shown in FIG. 19 is issued. Also, card buffer 75
After updating the card balance to the fractional amount in the fractional amount memory 78 and updating the final handling date to the current date stored in the clock circuit 34, the contents of the card buffer 75 are controlled by the card reader / writer. The data is transmitted to the card reader / writer 4 via the circuit 36 and written on the card. Thereafter, the contents of the card buffer 75 are incorporated into the sales information message and transmitted to the store processor 2 via the in-line circuit 3,
This processing ends.

On the other hand, when the sales information message is input from each POS terminal 1 via the in-line line 3, the CPU 11 of the store processor 2 is configured to execute the processing shown in FIG. That is, it is determined whether or not card data exists in the sales information message received first.
If it exists, the card number included in the card data is used as the card number area of the card management file 5.
B1 is searched, and the contents of the balance area B5 corresponding to the card number are changed to the balance data in the card data. Further, the contents of the handling last date area B4 corresponding to the card number are changed to the current date stored in the clock circuit 34 (last date setting means). Thereafter, various files in the disk memory 15 are updated based on the sales information in the message, and the process ends. If no card data is included in the message, the sales update process is immediately performed, and the process ends.

In the present embodiment configured as described above, the store issues a card in which a card number or the like is recorded in advance to a customer who wants to use the card, and operates the keyboard 22 of the store processor 2 by key operation. The card number, name and address corresponding to the management file 5 are set. At this time, the card balance of the card is “0 yen”. Then
The customer can use the card to pay and process the fraction of the purchase price.

That is, the customer hands the card along with the purchased product to the clerk. First, the clerk inserts the card into the card reader / writer 4 and presses the card key 61, and then operates the section key 53 and the like to execute the registration processing of the product for sale. Then, when all the products have been registered, the subtotal key 54 is pressed. Then, the card balance of the card is added to the total amount of the customer. Then, for the fraction unit of the fraction unit memory 79, a fraction amount of the above added amount is obtained, and this fraction amount is recorded as a card balance of the card. The amount obtained by subtracting the fractional amount from the added amount is displayed on the display 41 as the amount to be paid.

Now, the fractional unit is [10 yen] and the total amount of customers is [1010
3 yen] and the card balance of the card held by the customer is [8
In this case, a fractional amount [1 yen] is obtained.
Then, the card balance of the card is updated to [1 yen].
In addition, the amount of payment [10010 yen (10103 + 8−
3)] is displayed, and the total amount, the fractional amount, and the payment amount are printed on the receipt. Thereafter, when the clerk receives the cash corresponding to the payment amount from the customer, the clerk presses the deposit / current total key 55 to close the transaction. As a result, a customer receipt R5 as shown in FIG. 19 is issued. In addition, the contents of the balance area B5 corresponding to the card number in the card management file 5 are updated in the same manner as the card, and the last handling date is changed to the current date.

In this manner, the fractional amount of money when the customer makes a purchase and a fraction of a fraction is generated in the price is carried over to the next shopping as the card balance of the card. From the next time, the card balance in the card is added to the shopping price, and payment processing is performed for the added amount. However, if a fractional amount has also occurred in this additional amount, the fractional amount is updated as the card balance of the same card and carried over to the next shopping. Therefore, coins less than a fractional unit are not used for giving and receiving money for payment. Moreover, since the balance of the card always changes only in fractional amounts, even if the card is lost or damaged, the customer does not lose and the store damage is small.

Further, since the last date of handling of the card user is also managed by the card management file 5, by inspecting the file 5, the usage status of the card user can be grasped. Therefore, since the amount of money that has not been paid for the store is stored in the card, it is possible to take appropriate measures such as collecting a customer who does not use the card for a long time.

On the other hand, when the customer replaces the card with a new card due to loss or damage, the balance of the old card is surely guaranteed as the balance of the new card as in the first invention of the present application. However, even if the card is lost, there is no loss and the serviceability can be improved.

[Effects of the Invention] According to the present invention configured as described above, it is possible to provide a merchandise sales data processing device having the following effects. That is, according to the first aspect of the present invention, the fraction of money generated in the payment of the shopping price can be reduced from the card balance, and the balance of the card that can be processed for payment can be increased at any time by a simple key operation. Unless the card can be used for a long time. In addition, even if a card is lost or damaged, the balance of the lost or damaged card can be transferred to a new card and the card can be used continuously, so that the balance of the card paid in advance by the customer can be guaranteed, and the customer can lose money. Never do. Therefore, the usage rate of the card can be increased.

According to the invention of claim 2, the fractional amount generated in the payment of the shopping price is carried over to the next shopping as the balance of the card, the carried amount of the next shopping price is added and paid, and the fraction is added to the next payment. When the amount is generated, the fractional amount is further carried over as the balance of the card, so that the amount carried over as the balance of the card is small and the customer does not lose even if the card is lost or damaged. In addition, the damage to the store is small. It is also possible to easily find a card that has not been used for a long time from the contents of the card management file, and to collect the balance of the card from the card owner.
