Description

The present invention relates to a plurality of electronic cash registers (hereinafter referred to as ECs).
POS that manages data used in these ECRs and generated data by connecting R) via signal lines etc.
(Point-of-Sales: Point-of-Sales Information Management) system or sales registration device such as an electronic scale for face-to-face sales, in particular, a card in which the usable amount of money that can be used for payment is written (hereinafter, The present invention relates to a sales registration device that can use a prepaid card) and can manage customers.

“Conventional technology” In POS systems, a customer management system that provides rebate services has been introduced. Currently, there are various variations in the method of implementing the rebate service, but by issuing a membership card to a customer who became a member and presenting the membership card when the customer purchases a product, It is a general method to accumulate customer sales record data and implement a rebate service according to the sales record.

As a result, the store side has the advantage of increasing the effect of attracting customers and securing fixed customers. On the other hand, there is a merit that the customer side can receive more services.

In addition, recently, due to the relaxation of legal restrictions, some stores have adopted a POS system that allows payment with a prepaid card, and it is expected to spread rapidly in the future.

As described above, as the number of types of cards increases, it is inconvenient for customers. Therefore, it is conceivable to use one card as one card, for example, to manage customers by using a prepaid card.

For details of the prepaid card system that can use the above-mentioned membership card and prepaid card, refer to the specification and drawings attached to the application of Japanese Patent Application No. 1-194581 previously proposed by the applicant. Please refer.

[Problems to be Solved by the Invention] In the above-described conventional system, the following problems arise in terms of implementing a more fair service.

That is, since the prepaid card is a prepaid system, it is generally more advantageous for the store side than the customer. Therefore, in order to have many customers use the prepaid card, a premium amount is usually added to the prepaid card. For example, 10,000 yen can be purchased for 10,200 yen.

On the other hand, in the case of the conventional customer management system, a rebate service (premium) is provided later according to the purchase result data.

Therefore, when the payment is made using the prepaid card, the customer has already received sufficient service, and if a rebate service is provided for this, the service with the customer who made the payment without using the prepaid card becomes unbalanced. , Not preferable.

The present invention has been made in view of the above-mentioned circumstances, and uses a prepaid card as a membership card, and registers sales when the payment is made using the prepaid card and when the payment is not performed fairly. The purpose is to provide a device.

“Means for Solving the Problem” The invention according to claim 1 registers the sale of the product to each customer, calculates the total purchase amount of all the products sold to the customer, and can be used for payment. Read out the usable amount from the card in which the usable amount is written,

A writing means for writing a member number corresponding to a customer, a storage means for storing a rebate service target amount which is a cumulative value of the total purchase amount for each of the member numbers, and a purchase amount when the customer's total purchase amount is paid Of the total amount, the removal means for removing the amount paid for the usable amount of the card, and the rebate service target amount corresponding to the customer's membership number from the storage means is read out, and the rebate service target amount, A collection for adding the amount obtained by removing the amount paid for the usable amount of the card from the total purchase amount and storing it in the storage means. It is characterized by comprising a means.

According to a second aspect of the invention, in the first aspect of the invention, the writing means reads the usable amount and the membership number from the card that the customer currently owns when issuing a new card, and It is characterized in that the usable amount of money is added to the usable amount of money of the new card, and the membership number is written in the new card.

[Operation] According to the invention described in claim 1, the writing means writes a new usable amount and a membership number corresponding to a customer who owns the card on the card. Also, the removal means is
When paying the total purchase amount of the customer, the amount paid by the usable amount of the card is removed from the total purchase amount.
Then, the totaling means reads out the rebate service target amount corresponding to the member number of the customer from the storage means, and removes the rebate service target amount from the total purchase amount, which is the amount paid by the usable amount of the card. Is added and stored in the storage means.

According to the invention described in claim 2, in the invention described in claim 1, when issuing the new card, the writing means reads the usable amount and the membership number from the card currently owned by the customer, The usable amount is added to the usable amount of the new card, and the membership number is written on the new card.

Further, the magnetic card reader / writer 18 is provided with a printer, and as shown in FIG. 6, on the back of the prepaid card, the membership number (a in the figure) and the balance of the premium and old prepaid cards are shown in the purchase amount. In addition to printing the amount of money (b in the figure), the product purchase date and balance are printed in the prepaid printing area (c in the figure), and the service points are printed in the service point printing area (d). Here, the prepaid print area can print 16 rows and 2 lines, and the service point area can print 27 * 5 which is 10 service points. The prepaid card is used as a membership card even when the balance is 0 yen, and the service points are printed.

In addition, as shown in Fig. 4 as an option for each ECR2. A bar code scanner 19 or the like for reading the code data corresponding to the bar code from the bar code printed portion of the product and inputting it to the CPU 10 is provided.

In such a configuration, first, a schematic flow of issuing a prepaid card in ECR2 will be described with reference to FIG.

In this embodiment, the prepaid card issuance is
It is done in ECR2.

The prepaid card can be issued even during settlement (process x and y in FIG. 7).

The prepaid card issuance is a method in which the balance is not stored in advance in the prepaid card, but the customer's desired purchase amount is heard and written in the prepaid card at the time of issuance.

In this example, the condition to become a member is to purchase a prepaid card, but wish to join,
For customers who do not want 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 the prepaid card, the customer who wants to join the membership fills in the membership application form with predetermined items and submits it to the store (FIG. 7, process z). In this case, the number stored in the prepaid card as the identification number and printed on the back surface of the card becomes the membership number of the member.

The member who purchases the prepaid card for the second time submits the old prepaid card (issued in Figure 7). If you are a non-member, you do not need to submit your old prepaid card.

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

The balance and service points described above are printed on the back surface of the prepaid card (see FIG. 6).

Even in the case of non-members, the prepaid card stores the identification number (membership number) together with the balance, and the POS system of this embodiment manages the balance.

However, for non-members, a new identification number (membership number) is added each time a prepaid card is purchased.

In FIG. 7, “1. Issue” means that the customer passes the purchase amount to the store clerk at ECR2 and receives the prepaid card. Handing a prepaid card and receiving a new prepaid card.

Next, the CPU 10 of the ECR21 when a customer has a prepaid card issued by the clerk at the ECR21 of FIG.
Also, the processing of the clerk will be described based on the processing diagram of FIG.

First, when the customer stops at the ECR 21 and wants to purchase a prepaid card, the clerk proceeds to the process of step SA1, hears the desired purchase amount from the customer, and inputs it from the ten-key pad 12b of the operation unit 12. Usually, as shown in FIG. 9, a premium amount is added according to the desired purchase amount, so for example, if a customer wishes to purchase a 10,000 yen prepaid card,
When the clerk inputs 10,000 yen as the desired purchase amount using the ten-key pad 12b, the card balance at the time of issuing the prepaid card described later is 10,200 yen.

Further, instead of inputting the desired purchase amount with the ten keys 12b, the card type shown in FIG. 9, for example, 2 may be input.

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

Then, the process proceeds to step SA2.

In step SA2, the salesclerk inquires whether the customer is a member. Then, the determination result of step SA2 is "N
O ", that is, if the customer is not a member, proceed to step SA3.

In step SA3, the CUP10 is a magnetic card read / writer.
At 18, the balance data obtained by adding the premium amount to the desired purchase amount is magnetically stored in the prepaid card together with the new member number (used as card identification data) (hereinafter referred to as "write"). This process is performed because, in the present embodiment, the card number management is performed even when the customer is not a member, so it is necessary to store the member number. Then, the process proceeds to step SA7.

On the other hand, if the determination result of step SA2 is "YES", that is,
If the customer is a member, proceed to step SA4.

In step SA4, the store clerk receives the old prepaid card brought by the customer and inserts it into the card insertion slot 18a of the ECR 21. As a result, the CPU 10 causes the magnetic card read / writer 18 to read the stored contents of this old prepaid card (hereinafter referred to as read). The data to be read includes a membership number, a balance, and service points. Then, the process proceeds 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 (issue amount = desired purchase amount * premium amount) to obtain the new prepaid card balance, and then proceeds to step SA6. .

In step SA6, the CPU10 is the magnetic card read / writer.
Step 18, along with the membership number and service points
After writing the balance obtained in the process of SA5 to the prepaid card, the process proceeds to step SA7.

In step SA7, the CPU10 is the magnetic card read / writer.
At 18, the memory contents are printed on the back surface of the prepaid card, as shown in FIG. 6, and then the process proceeds to step SA8.

At step SA8, the customer file (see FIG. 3) stored in the hard disk is updated. If the member 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, a series of work is completed.

Next, regarding the processing of the store controller 1, the CPU 10 of the ECR2, the clerk and the customer when the customer stores the desired product for purchase in the basket while going around the sales floor and then comes to a certain checkout area in ECR2, the processing of FIG. It will be described with reference to the drawings.

When the customer brings in a plurality of products and requests payment, the clerk receives the product at a position facing the customer, and inputs the product code using the preset key 12c, the numeric keypad 12b and the function key 12a of the operation unit 12. Alternatively, the optional bar code scanner 19 is made to read the bar code of the product. As a result, the product code is transferred to the CPU 10.

From this, the CPU 10 proceeds to step SB1 and performs product registration processing. That is, the CPU 10 receives, through the signal line 3 and the communication interface 14, the data such as the product name and the equivalence of the product from the product file of the store controller 1 based on the product code. Meanwhile, store controller 1
Registers the product in the performance file. ECR2 CPU10
Displays the product name and unit price of the product on the display unit 11 and drives the printing unit 13 to print on the receipt paper.

Also, the CPU 10 sets the unit price of the product for which the product code is input to R
After accumulating in AM16, proceed to step SB2.

At step SB2, the CPU 10 determines whether or not the [subtotal] key is pressed. If the result of this determination is "NO", the input of code data for the next product is awaited. Therefore, when the next code data is supplied, the process returns to step SB1 to repeat the above-described product registration process.

When all the product registrations are completed and the clerk presses the [subtotal] key in the function key 12a, the determination result in step SB2 becomes "YES", and the process proceeds to step SB3.

In step SB3, the CPU 10 displays the total amount on the display unit 11 and drives the printing unit 13 to print on the receipt paper. The total amount of money 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 proceeds to step SB4.

In step SB4, the store clerk inquires of the customer whether or not he is a member, and if there is a member, the process proceeds to step SB5.

In step SB5, the clerk receives the prepaid card from the customer and inquires whether or not he / she wants to make a payment with the prepaid card. If the customer does not wish to make a payment with the prepaid card, the process proceeds to step SB6.

In step SB6, the clerk uses the prepaid card received from the customer as a membership card. That is, the store clerk causes the magnetic card read / writer 18 to read the contents (member number, balance, service points) stored in the prepaid card. Then, the process proceeds to step SB7.

In step SB7, the clerk inquires whether or not the customer desires to implement the service, and if so, implements the service. Here, for the details of this processing,
A description will be given based on the processing diagram of the figure.

First, the store clerk proceeds to the process of step SC1, inquires of the customer whether or not to use the service score, and if desired, proceeds to step SC2.

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

In step SC3, the service score is set to "0", and then the process returns to the main routine, that is, step SB8.

On the other hand, if the determination result of step SC1 is "NO", that is,
If the customer does not wish to carry out the service, the process returns to the main routine, that is, step SB8.

In this embodiment, one service point is converted into a discount amount of 1 yen, and when the service point is larger than the total amount, the total amount is "0" in the processing of step SC2. And In other words, the service points are not returned to the customer in cash, and the excess is discarded.

At step SB8, when the store clerk receives the deposit amount from the customer, the deposit amount is set on the ten key 12b of the operation unit 12.
Input, and then press the [Saving / Total] key. As a result, the CPU 10 proceeds to the process of step SB9.

At step SB9, the CPU 10 performs change calculation, display and printing. That is, the calculation represented by the following formula is performed, and after displaying the amount of the change on the display 11a for the clerk and the display 11b for the customer, the printing unit 13 is driven and the deposit amount and the calculated change are displayed on the receipt paper. Print it. And step SB
Go to 10.

Deposit amount-Purchase amount = Change In step SB10, the CPU 10 accumulates the service target amount. However, when the service is implemented in the process of step SB7, the target amount of money is cleared. Then, the process proceeds to step SB11.

In step SB11, the CPU 10 calculates the service score based on the cumulative value accumulated in the process of step SB10 described above, and then proceeds to step SB12.

In step SB12, the CPU 10 causes the magnetic card read / writer 18 to write the card balance and service points on the prepaid card, and then proceeds to step SB13.

In step SB13, the CPU 10 causes the magnetic card read / writer 18 to print the content written on the prepaid card in the process of step SB12 described above on the back surface of the prepaid card, as shown in FIG. After ejecting from the insertion opening 8a, the process proceeds to step SB14.

In step SB14, the store controller 1 receives the data from the ECR 2 via the signal line 3 and the communication control unit 9 and updates the customer file of the hard disk device 5.
That is, a new balance, service points, etc. are stored in the customer file. Then, the process proceeds to step SB15.

In step SB15, 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 store clerk ends the series of operations after giving the receipt and change to the customer.

On the other hand, if the determination result of step SB5 is "YES", that is,
If the customer wishes to make a payment with a prepaid card, he / she presses a command key to that effect, for example, a prepaid card key, and then proceeds to step SB16.

At step SB16, the store clerk reads the magnetic card reader / writer.
At 18, the contents (member number, balance, service points) stored in the prepaid card are read. Then, the process proceeds to step SB17.

In step SB17, the clerk inquires whether the customer wants to implement the service, and if so, implements the service (the same process as step SB7). Then, the process proceeds to step SB18.

At step SB18, the CPU 10 calculates a new balance. That is, after performing the calculation shown in the following equation, the process proceeds to step SB19.

New balance = balance−total amount In step SB19, it is determined whether or not the new balance is negative, that is, the balance of the prepaid card is smaller than the total amount. If this determination result is "YES", the process proceeds to step SB20.

In step SB20, the clerk inquires of the customer whether to purchase a new prepaid card or to settle the shortfall by cash, and if the customer wants to settle the shortfall of the prepaid card by cash, , Go to step SB21.

In step SB21, 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 SB20 is "YES", that is, if the customer desires to purchase a prepaid card, the process proceeds to step SB22.

In step SB22, the store clerk listens to the desired purchase amount from the customer and inputs it from the numeric keypad 12b of the operation unit 12, and then in step S22.
Go to B23.

At step SB23, the CPU 10 calculates a new balance. That is, after performing the calculation shown in the following equation, the process proceeds to step SB12.

New balance = purchase amount + premium amount + new balance calculated in the process of step SB18 (this is a negative value itself) On the other hand, if the determination result of step SB4 is "NO", that is, if the customer is not a member, step SB24 Go to.

In step SB24, the clerk inquires of the customer whether he / she wishes to make a payment with a prepaid card. And
If the customer wishes to make a payment with a prepaid card, proceed to step SB25.

In step SB25, the CPU 10 causes the magnetic card read / writer 18 to read the contents (member number, balance) stored in the prepaid card. And step
Continue to SB26.

At step SB26, the CPU 10 calculates a new balance. That is, after performing the calculation shown in the following equation, the process proceeds to step SB27.

New balance = balance−total amount In step SB27, it is determined whether the new balance is negative, that is, the balance of the prepaid card is smaller than the total amount. If this determination result is "YES", then step SB28
Go to.

In step SB28, the clerk inquires of the customer whether to purchase a new prepaid card or to settle the shortage with cash, and if the customer desires to purchase the prepaid card, the process proceeds to step SB29.

In step SB29, the clerk asks the customer for the desired purchase amount and inputs it through the ten-key pad 12b of the operation unit 12, and then in step S29.
Go to B30.

At step SB30, the CPU 10 calculates a new balance. That is, after performing the calculation shown in the following equation, the process proceeds to step SB12.

New balance = purchase amount + premium amount + new balance calculated in the process of step SB26 (it is a negative value itself) On the other hand, when the judgment result of step SB28 is "NO", that is,
If the customer wants to settle the shortage with cash, proceed to step SB31.

In step SB31, the clerk sets the balance of the prepaid card to "0", and then proceeds to step SB32.

In step SB32, the CPU 10 causes the magnetic card read / writer 18 to write the card balance “0” to the prepaid card, and then proceeds to step SB33.

In step SB33, the CPU 10 causes the magnetic card read / writer 18 to print the content written on the prepaid card in the process of step SB32 described above on the back surface of the prepaid card as shown in FIG. , Is not a member, so the service score does not occur, so the service score is not printed.) Then, after ejecting the prepaid card from the card insertion slot 18a, the process proceeds to step SB34.

In step SB34, the store controller 1 receives the data from the ECR 2 via the signal line 3 and the communication controller 9 and updates the customer file of the hard disk device 5.
That is, a new balance, that is, "0" is stored in the customer file. Then, the process proceeds to step SB35.

At step SB35, when the store clerk receives the deposit amount from the customer, the store clerk uses the deposit amount on the ten key 12b of the operation unit 12.
Input by, and then press the [Deposit / Account] key. As a result, the CPU 10 proceeds to the process of step SB36.

At step SB36, the CPU 10 performs change calculation, display and printing. That is, the calculation shown in the following formula is performed, and after displaying the amount of the change on the display 11a for the clerk and the display 11b for the customer, the printing unit 13 is driven and the deposit amount and the calculated change are displayed on the receipt paper. Print it. And step SB
Proceed to 15.

Deposit amount-Purchase amount = Change On the other hand, when the result of the determination in step SB24 is "NO", that is,
If the customer does not wish to make a payment with the prepaid card, proceed to step SB35.

By the way, in the above-described processing, there are three possible examples of the case where the customer has a prepaid card, but pays with cash instead of the prepaid card.

(A) When the balance of the prepaid card is “0”.

(B) When the balance of the prepaid card is less than the total amount, and the customer pays for the shortage with cash.

(C) The balance of the prepaid card is not "0", but if you want to destroy a large amount of bills or the total amount is high, the balance of the prepaid card will be "0", so this time only special cash If you wish to be paid by.

In the above-described embodiment, an example of a system for issuing a prepaid card by each ECR 2 arranged in the sales floor is shown, but a system as shown below may be used.

A type issued only from ECR2 arranged in the service counter, for example, ECR21 in FIG.

In this case, the ECR 21 is arranged in the service counter and is an ECR 2 dedicated to issuing a prepaid card, and the other ECR 2 does not issue the prepaid card.

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

The card is issued by the customer by the card issuing machine 20. still,
For details of the automatic card issuing machine, see Japanese Patent Application No. 1 mentioned above.
See the specification and drawings accompanying the 194581 application.

Further, although the store controller type POS system has been described in the above-described embodiment, the present invention may be applied to a master / clave type POS system or a single ECR.

Further, the present invention may be applied to an electronic balance for face-to-face sales having ECR and POS functions.

In addition, in the above-described embodiment, an example in which only the desired service points cannot be used has been shown, but only the desired service points may be used.

Further, in the above-described embodiment, an example of the service in which the price is discounted according to the service score is shown, but the service may be a gift presenting gift according to the service score.

Further, in the above-described embodiment, the example of the prepaid card using the magnetic storage is shown, but the prepaid card using the storage means such as the IC memory may be used.

[Advantages of the Invention] As described above, according to the present invention, customer management can be performed using a prepaid card. That is, the prepaid card and the membership card can be used together.

Therefore, the customer does not have the inconvenience of carrying two cards and shopping.

On the other hand, for the store side, it is possible to save the trouble of issuing two types of cards, which results in cost reduction.

In this case, the amount settled in cash will be removed from the total as the amount to be rebated, so if the settlement is made using a prepaid card, a double service will be provided, and the disadvantage that the service will be unbalanced is solved. It
