Description

DETAILED DESCRIPTION OF THE INVENTION "Field of Industrial Application" The present invention applies to a plurality of electronic cash registers (hereinafter referred to as EC
These ECH
Sales data processing devices such as POS (Point-Of-Sales) systems and electronic scales for face-to-face sales that manage data used and generated in The present invention relates to a sales data processing device that can use a card (hereinafter referred to as a prepaid card) that can be purchased with a monetary amount and can purchase products instead of cash, and can perform customer management.

"Prior Art" In POS systems, customer management systems that provide rebate services, etc. have been introduced and have been well received. Currently, there are various variations in the implementation method of the rebate service, but in order to inform the customer of the service points accrued from the current purchase and the cumulative number of service points accrued from previous purchases, the rebate service will be displayed on the receipt paper. There is a method that prints the total service score along with the service score of
(see publication).

In addition, a POS system has been developed that allows payments to be made using a card (hereinafter referred to as a "prepaid card") that can be purchased for a predetermined amount of money in place of cash, and is attracting attention.

Methods for displaying the balance on this prepaid card include a method of punching holes according to the balance, like a telephone card, and a method of printing the balance on the back of the prepaid card.

Customer management systems in POS systems are popular and have been adopted by many stores, and it is expected that POS systems that allow payment using prepaid cards will rapidly become popular. We have previously proposed a prepaid card system that can be used as both a membership card and a prepaid card (see the specification and drawings attached to Japanese Patent Application No. 1-194581).

"Problem to be solved by the invention" By the way, in the conventional customer management system mentioned above,
The method of printing the cumulative service points on the receipt is to tell the customer how many service points he or she currently has when shopping.
It is preferable to be able to check whether the customer has the service amount (service amount).

However, the above-mentioned method is limited to simply providing a service score notification service to the customer, and cannot directly convert the receipt into a service coupon (golden coupon) for the total service score. In other words, the cumulative service points are printed on the receipt each time the customer makes a purchase, but if this is used as a service ticket, and the customer brings the receipt and requests a service, the store will be able to print it on the receipt. This is because it is not possible to confirm whether or not the receipt is the latest one.

For example, in reality, only the latest receipt from today's shopping shown in Figure 16(a) should be valid.
When a customer brings in a receipt from yesterday's shopping shown in FIG. 16(b), the store cannot check it.

Therefore, even if the total service points are printed on the receipt, the service ticket itself must be issued separately and delivered to the customer by mail or the like. Therefore, the time and expense were a heavy burden on the store side.

As shown in Figures 17 (a) and (b), it is possible to print only the service points that occurred today on the receipt and use this as a service ticket, but in this case, customers can It is not practical as it is necessary to bring the receipts and add up the service points.

The present invention has been made in view of the above-mentioned circumstances, and in a sales data processing device that performs customer management using a prepaid card, the prepaid card can be effectively used, and there is no need to issue service coupons (golden coupons). The purpose is to provide a sales data processing device.

"Means for Solving the Problem" The invention according to claim 1 provides a sales data processing device that allows payment using a pre-purchased card instead of cash.
a writing means for writing a balance and a membership number corresponding to the customer on the card; a calculation means for calculating a rebate service score based on the customer's purchase history; and a calculation means for writing the balance and the customer's current rebate service score on the card. The card is characterized in that it is equipped with a printing means for printing a cumulative value, and the card is used as a membership card for customer management.

The invention as set forth in claim 2 is characterized in that in the invention as set forth in claim I, the printing means prints the service points on the card by a number of symbols corresponding to the points.

Furthermore, the invention according to claim 3 is characterized in that in the invention according to claim 2, the printing means erases the used service points by overwriting.

"Operation" According to the invention described in claim 1, the writing means writes the balance and the membership number corresponding to the customer on the card.

Further, the calculating means calculates the rebate service points based on the customer's purchase history, and the printing means prints the balance and the cumulative value of the customer's current rebate service points on the card.

This card is then used as a membership card for customer management.

According to the second aspect of the invention, in the first aspect of the invention, the printing means prints the service points on the card using the number of symbols corresponding to the points.

Furthermore, according to the invention set forth in claim 3, in the invention set forth in claim 2, the printing means erases the used service points by overwriting.

A hard disk device 5 drives a hard disk serving as an external storage device in which application programs and various data are stored.

Here, FIG. 3 shows an example of the structure of a customer file stored on the hard disk. This customer file is a file that stores member data (name, address, telephone number, total issuance number, card balance, cumulative purchases, cumulative amount of service, service points, etc.) in association with the member number.

Note that the above-mentioned membership number is given to the customer when he or she first purchases a prepaid card. Thereafter, when the customer brings the old prepaid card to purchase a new prepaid card, the membership number of the prepaid card is written on the new prepaid card.

Further, the above-mentioned total issuance number is a total number that indicates how many prepaid cards have been issued to the member number up to now. For details on the total issue number, please refer to
Please refer to the specification and drawings attached to the above-mentioned Japanese Patent Application No. 1-194581.

The customer file mentioned above is ECR2°~2. ．．

Furthermore, 17 is a cash drawer in which cash is stored, and IS is a magnetic card reader/writer that reads various data such as membership numbers stored in prepaid cards and writes balances, and is located in the prepaid card insertion slot shown in Fig. By inserting a prepaid card through the prepaid card slot 18a, various data such as a membership number are read from the prepaid card and written therein, and then the prepaid card is ejected from the prepaid card insertion slot 18a.

The magnetic card reader/writer 18 is also equipped with a printer, which prints the membership number (a) on the back of the prepaid card, the purchase amount, the premium, and the balance of the old prepaid card, as shown in FIG. In addition to printing the amount including (b) in the same figure, the prepaid printing area (
The product purchase date and balance are printed in C) of the same figure, and the service points are printed in the service score printing area (D of the same figure).

Here, the prepaid printing area is capable of printing in 16 rows and 2 rows, and the service score area is capable of printing 27 *, which is a service score of 10 points, in 5 rows.

Furthermore, a prepaid card can be used as a membership card even when the balance is 0 yen, and service points are printed on it.

As shown in FIG. 4, each ECR 2 is also optionally provided with a barcode scanner 19, etc., which reads code data corresponding to the barcode from the barcode printed portion of the product and inputs it to the CPU10.

In such a configuration, first, a general flow of issuing a prepaid card in the ECR 2 will be described with reference to FIG.

■In this example, the issuance of prepaid cards is as follows:
This is done in ECR2.

- A prepaid card can be issued even during the payment process (processes 2 and y in Figure 7).

■Prepaid cards are issued by asking customers for their desired purchase amount and writing it into the prepaid card at the time of issuance, rather than having the balance stored in the prepaid card in advance.

■In this example, the condition for becoming a member is to purchase a prepaid card, but if you wish to become a member,
For customers who do not wish to purchase a prepaid card, it is possible to issue a prepaid card with a balance of "0", that is, a membership card.

- After purchasing a prepaid card, a customer who wishes to become a member fills in the specified items on a membership application form and submits it to the store (Process 2 in Figure 7). In this case, the number stored in the prepaid card as an identification number and printed on the back of the card becomes the member's membership number.

■Members purchasing a prepaid card for the second time submit their old prepaid card (Figure 7 Country = IN). If you are a non-member, you do not need to submit your old prepaid card.

■For members, the membership number, balance, and service points are stored in the prepaid card. When purchasing a new prepaid card, the membership number and service points of the old prepaid card are written on the new prepaid card. Also, the balance of the old prepaid card is added to the balance of the new prepaid card and stored.

■The above-mentioned balance and service points are printed on the back of the Vliveid card (see Figure 6).

(2) An identification number (membership number) is stored in the prepaid card along with the balance even in the case of a non-member, and the balance is managed in the POS system of this embodiment.

[Shi] However, if you are a non-member, a new identification number (membership number) will be added each time you purchase a prepaid card.

In Figure 7, "Koro■" means that the customer is using EC.
At R2, the customer hands over the purchase amount to the clerk and receives the prepaid card.
At CR2, the customer hands over the purchase amount and the old prepaid card, and receives a new prepaid card.

Next, ECR2 when a certain customer has a prepaid card issued by a clerk at ECR2 in Figure 1.
The processing of the + CPU10 and the store clerk will be explained based on the processing diagram of FIG.

First, when a customer stops by the ECR 2 and wishes to purchase a prepaid card, the clerk proceeds to step SAI, asks the customer for the desired purchase amount, and inputs it from the numeric keypad 12b of the operation unit 12. Normally, as shown in Figure 9, a premium amount is added depending on the desired purchase amount, so for example, if a customer wishes to purchase a prepaid card worth 10,000 yen, the clerk will set the desired purchase amount as 10,000 yen.
If you enter 00 yen using the numeric keypad 12b, the card balance at the time of issuance of the prepaid card (described later) will be 10.200 yen.
It becomes a yen.

Furthermore, instead of inputting the desired purchase amount using the numeric keypad 12b, the card type shown in FIG. 9, for example, the card type, may be input.

Furthermore, the premium amount may be different for members and non-members.

Then, the process advances to step SA2.

In step SA2, the store clerk inquires whether the customer is a member. If the determination result in step SA2 is rNOJ, that is, the customer is not a member, the process advances to step SA3.

In step SA3, the CPU 10 causes the magnetic card reader/writer 18 to magnetically record the balance data, in which the premium amount is added to the desired purchase amount, on the prepaid card along with the new membership number (used as card identification data) (hereinafter, write ). This process is performed because, in this embodiment, the card balance is managed even when the customer is not a member, so it is necessary to remember the membership number. Then, the process advances to step SA7.

On the other hand, if the determination result in step SA2 is rYEsJ,
That is, if the customer is a member, the process advances to step SA4.

In step SA4, the clerk takes the old prepaid card brought by the customer and inserts the card into ECR2□.
Insert into 8a. As a result, the CPU 10 uses the magnetic card reader/writer 18 to read the stored contents of this old prepaid card (hereinafter referred to as "read"). Leading data includes membership number, balance, and service points.

Then, the process advances to step SA5.

In step SA5, the CPU 10 adds the balance of the read old prepaid card to the balance of the new prepaid card (issued amount = desired purchase amount + premium amount) to obtain the balance of the new prepaid card, and then proceeds to step SA6.

In step SAG, the CPU 10 uses the magnetic card reader/writer 18 to write the membership number, service points, and balance obtained in the process of step SA5 to the prepaid card, and then proceeds to step SA7.

In step SA7, the CPU 10 uses the magnetic card reader/writer 18 to print the stored contents on the back side of the prepaid card, as shown in FIG. 6, and then proceeds to step SA8.

In step SA8, the customer file (see FIG. 3) stored on the hard disk is updated.

If the user is not a member, the card balance corresponding to the member number stored in the prepaid card in the process of step SA3 is stored. Then, the series of tasks is completed.

Next, the store controller 1. stores the products the customer wants to purchase in the cart while walking around the sales floor, and then comes to the checkout area, which is a branch of ECR2. ECR2 CP
tJ 10, the processing of the clerk and the customer will be explained based on the processing diagram of FIG.

When a customer brings a plurality of products and asks for payment, the store clerk picks up the products at a position facing the customer and inputs the product code using the preset key 12c, numeric keypad 12b, and function key 12a of the operation section 12. Alternatively, the optional barcode scanner 19 is made to read the barcode of the product. As a result, the product code is C
Transferred to PU10.

From this point, the CPUfO proceeds to step SBI and performs product registration processing. That is, the CPU 10 receives data such as the product name and unit price of the product from the product file of the store controller 1 via the signal line 3 and the communication interface 14 based on the product code. On the other hand, the store controller 1 registers the product in the performance file.

The CPU 10 of the ECR 2 displays the product name and unit price on the display section 11, and also drives the printing section 13 to print on the receipt paper.

Further, the CPU 10 accumulates the unit prices of the products whose product codes have been input in the RAM 16, and then proceeds to step SB2.

In step SB2, the CPU 10 determines whether the [Subtotal] key has been pressed. If the result of this judgment is "NO", the system waits for the code data of the next product to be input. Therefore,
When the next code data is supplied, the process returns to step SB1 and the above-described product registration process is repeated.

Then, when all product registration is completed and the clerk presses the U subtotal key in the function key 12a, step SB
The determination result of step 2 is rYEsJ, and the process advances to step SB3.

In step SB3, the CPU 10 displays the total amount on the display section 11 and drives the printing section 13 to print on the receipt paper. The total amount is the total price of the products purchased by the customer, and is the amount that the customer should pay to the store. Then, the process advances to step SB4.

In step SB4, the clerk asks the customer whether or not he or she is a member, and if the customer is a member, step SB5
Proceed to.

In step SB5, the store clerk receives the prepaid card from the customer and inquires as to whether or not the customer wishes to settle the bill using the prepaid card. Then, if you do not wish to settle the payment using a prepaid card, step SB6
Proceed to.

In step SB6, the clerk uses the prepaid card received from the customer as a membership card.

In other words, the clerk is a magnetic card reader/writer! At step 8, the contents stored in the prepaid card (membership number, balance, service points) are read.

Then, the process advances to step SB7.

In step SB7, the clerk inquires whether the customer wishes to perform the service, and if so, performs the service. Here, details of this process will be explained based on the process diagram of FIG. 11.

First, the clerk proceeds to step SCI, inquires of the customer whether or not to use service points, and if so, proceeds to step SC2.

In step SC2, the clerk subtracts the service points from the total amount, and then proceeds to step SC3.

In step SC3, after setting the service score to "0",
Return to the main routine, ie, step SB8.

On the other hand, if the determination result in step SCI is rNOJ, that is, if the customer does not wish to perform the service, the process returns to the main routine, that is, step SB8.

In this embodiment, one service point is converted to a discount amount of 1 yen, and if the service point is greater than the total amount, the total amount is set to rOJ in the process of step SC2. . In other words, the service points are not returned to the customer in cash, but the surplus is thrown away.

In step SB8, the clerk receives the deposit amount from the customer, inputs the deposit amount using the numeric keypad 12b of the operation section 12, and then presses the [Deposit/Cash Total] key. Thereby, CPU10 proceeds to the process of step SB9.

In step SB9, CPU10 calculates, displays, and prints change. That is, the calculation shown in the following equation is performed, and the amount of change is displayed on the clerk's display 11a and the customer's display 11.
After displaying the amount on the receipt paper, the printing unit 13 is driven to print the deposited amount and the calculated change on the receipt paper. Then, proceed to step 5 BIO.

Deposit amount - purchase amount = change In step 5 BIO, CPtJlo accumulates the amount of money to be serviced. However, if the service is performed in the process of step SB7, the target amount for that service is cleared. Then, the process advances to step 5B11.

In step SBI+, the CPU 10 calculates the service score based on the cumulative value accumulated in the process of step 5BIO described above, and then proceeds to step 5B12.

In step 5B12, the CPU 10 causes the magnetic card reader/writer 18 to write the card balance and service points to the prepaid card, and then in step 5BI3
Proceed to.

In step 5B13, the CPU 10 uses the magnetic card reader/writer 18 to write the contents written to the prepaid card in the process of step 5BI2 described above.
As shown in FIG. 6, after printing on the back of the prepaid card, the card is ejected from the card insertion slot 18a, and then the process proceeds to step 5B14.

In step 5BI4, the store controller 1 stores the EC
Data is received and received from R2 via the signal line 3 and the communication control unit 9, and the customer file in the hard disk drive 5 is updated. That is, new balances, service points, etc. are stored in the customer file. Then, the process advances to step 5B15.

In step 5B15, the CPU 10 drives the printing unit 13 to feed a predetermined amount of the receipt, and then cuts and issues the receipt.

As a result, the clerk hands over the receipt and change to the customer, and then completes the series of operations.

On the other hand, if the determination result in step SB5 is rYESJ,
That is, if a customer wishes to pay with a prepaid card, a command key to that effect, for example, Ig'
After pressing the +' key, proceed to step 5BI6.

In step 5B16, the clerk causes the magnetic card reader/writer 18 to read the contents (membership number, balance, service points) stored in the prepaid card.

Then, the process advances to step 5B17.

In step 5B17, the clerk inquires whether the customer wishes to perform the service, and if so, performs the service (same process as step SB7). Then, the process advances to step 5B18.

In step 5B18, CPU10 calculates the new balance. That is, after performing the calculation shown in the following equation, step 5B
Proceed to step 19.

New Balance = Balance - Total Amount In step 5B19, it is determined whether the new balance is negative, that is, the balance of the prepaid card is smaller than the total amount. If the result of this determination is rYEsJ, the process advances to step 5R20.

In step 5B20, the clerk asks the customer whether to purchase a new prepaid card or settle the missing amount with cash, and if the customer wishes to settle the missing amount with cash, , proceed to step SB2'l.

In step 5B21, the clerk sets the balance of the prepaid card to "0" and then proceeds to step SB8.

On the other hand, if the determination result in step 5B20 is rYESJ, that is, if the customer wishes to purchase a prepaid card, the process proceeds to step 5B22.

In step 5B22, the store clerk asks the customer for the desired purchase amount, inputs it from the numeric keypad 12b of the operation unit 12, and then
Proceed to step 5B23.

In step 5B23, CPU10 calculates the new balance. That is, after performing the calculation shown in the following equation, step 5B
Proceed to I2.

New balance = Purchase amount + Premium amount + Step 5B1B
On the other hand, if the determination result in step SB4 is "NO", that is, the customer is not a member, the process proceeds to step 5B24.

In step 5B24, the clerk asks the customer whether or not he or she wishes to pay with a prepaid card. If the customer wishes to pay with a prepaid card, the process proceeds to step 5B25.

In step 5BZ5, the CPU 10 causes the magnetic card reader/writer 18 to read the contents (membership number, balance) stored in the prepaid card. and,
Proceed to step 5R26.

In step 5826, cputo calculates the new balance. That is, after performing the calculation shown in the following equation, step 5B
Proceed to 27.

New Balance = Balance - Total Amount In step 5B27, it is determined whether the new balance is negative, that is, the balance of the prepaid card is smaller than the total amount. If the result of this determination is rYEsJ, the process advances to step 5B2B.

In step 582B, the clerk inquires of the customer whether to purchase a new prepaid card or settle the missing amount in cash. If the customer wishes to purchase a prepaid card, the process proceeds to step 5B29.

In step 5B29, the store clerk asks the customer for the desired purchase amount, inputs it from the numeric keypad 12b of the operation unit 12, and then
Proceed to step SB30.

In step 5B30, CPU10 calculates the new balance. That is, after performing the calculation shown in the following equation, step 5B
Proceed to I2.

New balance = purchase amount + premium amount + step 582B
The new balance calculated in the process (this itself is a negative value) On the other hand, if the judgment result in step 582B is "NO",
That is, if the customer wishes to settle the missing amount in cash, the process proceeds to step 5B31.

In step SB31, the clerk sets the balance of the prepaid card to "0" and then proceeds to step 5B32.

In step SB32, the CPU 10 causes the magnetic card reader/writer 18 to write the card balance "0" to the prepaid card, and then proceeds to step 5B33.

In step 5B33, the CPU 10 causes the magnetic card reader/writer 18 to print the contents written to the prepaid card in the process of step 5B32 described above on the back side of the prepaid card as shown in FIG. (Since they are not members, no service points will be generated, so the service points will not be printed.)

After the prepaid card is ejected from the card insertion 018a, the process advances to step 5B34.

In step 5B34, the store controller 1 stores the EC
Data is received and received from R2 via the signal line 3 and the communication control unit 9, and the customer file in the hard disk drive 5 is updated. i.e. new balance in customer file i.e. "0"
to remember. Then, the process advances to step 5B35.

In step 5B35, the clerk receives the deposit amount from the customer, inputs the deposit amount using the numeric keypad 12b of the operation section 12, and then presses the [Deposit/Cash Total] key. Thereby, CPU10 proceeds to the process of step 5R3B.

In step 5B36, the CPU 10 calculates, displays, and prints the change. That is, the calculation shown in the following formula is performed, and the amount of change is displayed on the clerk's display 11a and the customer's display t.
tb, the printing unit 13 is driven to print the deposited amount and the calculated change on the receipt paper. Then, proceed to step 5BI5.

Deposit amount - Purchase amount = Change On the other hand, if the judgment result in step 5B24 is rNOJ,
That is, if the customer does not wish to pay with a prepaid card, the process proceeds to step 5B35.

By the way, in the above-mentioned process, the following three cases are possible where the customer settles the payment with cash instead of using a prepaid card even though the customer has a prepaid card.

(a) If the prepaid card balance is "0".

(b) When the balance on the prepaid card is less than the total amount and the customer settles the shortfall in cash.

(C) The balance on the prepaid card is not ``0'', but if you want to destroy a large amount of banknotes or the total amount is large, the balance on the prepaid card will be ``0'', so you can use cash only this time. If you wish to settle the payment by

In the embodiment described above, an example of a system is shown in which prepaid cards are issued by each ECR 2 placed in a sales floor, but a system as shown below may also be used.

- A type that issues only the ECR2 located at the service counter, for example, the ECR2 shown in FIG.

In this case, ECR2+ is located at the service counter and is dedicated to issuing prepaid cards, and other ECR2+
CR2 does not issue prepaid cards.

■As shown in FIG. 12, a type issued by an automatic card issuing machine 20.

The customer issues the card himself using the automatic card issuing machine 20. For details of the automatic card issuing machine, please refer to the specification and drawings attached to the above-mentioned Japanese Patent Application No. 1-194581.

Further, in the above embodiment, a store controller type POS system has been described, but the present invention may be applied to a mask/slave type POS system or an ECR alone.

Furthermore, the present invention may be applied to an electronic scale for face-to-face sales that is equipped with ECR and POS functions.

In addition, in the embodiment described above, as shown in FIG. point), etc.

In addition, in the embodiment described above, an example was shown in which the service points were printed separately from the date, but as shown in FIG. It is also possible.

Further, in the embodiment described above, an example was shown in which the customer cannot use only the desired service points, but it is also possible to use only the desired service points.

Here, in the case where the customer cannot use only the desired service points, examples of printing in which the used service points are erased by overwriting the horizontal lines are shown in Figures 14 (,) and (b).
).

Further, in a case where the customer can use only the desired service points, examples of printing when the service points are left are shown in FIGS. 15(a) and 15(b). Figure 15 (
a) is the case where 30 out of 50 points are used;
Figure 5(b) shows the case where 50 out of 75 points were used on May 20th.

In addition, in the embodiment described above, an example was shown in which the amount of money paid by a prepaid card is not eligible for rebate. This is intended to provide fairer service, but is not limited to this configuration. In short, it suffices if the membership card and prepaid card can be used together. In addition, in the above-mentioned embodiment, the prepaid card is used up and its balance becomes "
0" is still referred to as a prepaid card.

In addition, in the embodiment described above, an example was shown in which the service points are stored in the prepaid card, but the service points themselves are stored in the customer file by the POS system, so they cannot be stored in the prepaid card itself. There is no need to leave it there. The same can be said for the card balance, but it seems that the card balance data itself is generally stored in the prepaid card. In the embodiment described above, the card balance itself is also managed in the POS system.

Further, in the embodiment described above, an example of a service that provides discounts based on service points is shown, but it may also be a service that presents prizes according to service points.
