Abstract

PURPOSE:To prevent time from being prolonged for check-out work by processing the fraction of change by using a service point based on the purchasing amount of a customer. CONSTITUTION:When customer data are inputted from a magnetic card reader/ writer 2, a customer identification number or the service point is sent to a printer 5 and printed on a receipt by a CPU 9. When an inputted bar code is a commodity number, the price of a the commodity is read out of an auxiliary storage device 8 and displayed on a display 4 by the CPU 9. Further, the printer 5 is driven and the price is printed on the receipt. This operation is repeated for each commodity. When a received amount is inputted, the amount is displayed on the display 4 and printed through the printer 5 to the receipt by the CPU 9. The fraction is subtracted from the service point and an amount, for which the above mentioned fraction is subtracted from the total purchasing amount, is subtracted from the received amount, defined as the change, displayed on the display 4 and printed through the printer 5 to the receipt.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a PoS system for managing product sales in retail stores and the like.

[Conventional technology]

The occurrence of change that includes fractions of less than 10 yen at the cash registers of retail stores, etc. makes the checkout process complicated and time-consuming for retailers due to the handling of 1 yen coins and 5 yen coins, and also makes it difficult for customers to On the other hand, there are inconveniences such as longer waiting times and increased wallet size due to the increase in the number of 1-yen and 5-yen coins.

Conventionally, as systems for solving these inconveniences, there have been systems using prepaid cards, systems using credit cards, systems using online cards, etc.

[Problem to be solved by the invention]

However, in systems that use prepaid cards, customers usually have to purchase a card worth between 1,000 to several tens of thousands of yen before purchasing a product, which is too much of a burden on the customer, and if the card is lost, the customer will have to pay for it. The problem was that the company suffered unilateral damage. In addition, systems that use credit cards require filling in and signing numerous items on a predetermined form, and are not expected to be very effective in simplifying or reducing work time. Since this is relatively large, there is a problem in that if the system is operated by another person, the damage to the customer or credit card company will be large. Furthermore, in a system using an online card, an online line to a bank account or the like is indispensable, which poses the problem of high costs when introducing the system.

In view of the above-mentioned problems, the present invention is capable of processing fractions of change without making checkout nest creation complicated or taking a long time, and yet burdens customers and retailers with upfront investment. The purpose of the present invention is to provide an inexpensive system that does not cause any damage and causes less damage in the event of an accident.

[Means to solve the problem]

Figure 1 shows an overview of the POS system of the present invention.
A customer identification means records customer data including data on service points calculated according to predetermined conditions based on past purchase totals for each of a large number of customers, and customer identification information for identifying a customer attempting to check out; customer data reading means C for reading the customer data from the customer identification means; and purchase amount input means d for inputting the purchase amount of the customer.
, a deposit amount input means e for inputting the deposit amount from the customer, a purchase total calculation means f for calculating the total purchase amount, and a service score calculation for calculating the service score according to predetermined conditions based on the purchase total amount. means g, and a change calculation means that calculates change by subtracting a fraction of the total purchase price that is less than or equal to a preset digit from the service points or the service points in the read customer data, and subtracting the remaining amount from the deposited amount. and a customer data updating means i for updating the contents of the customer identification means by using the sum of the service points after subtracting the fraction and the service points in the customer data as a new service point in the customer data, and the customer data, purchase amount, and purchase amount. It consists of a display output means j for visually displaying the total amount, deposited amount, change, etc. or converting it into a hard copy.

[For production]

The customer data of the customer who wishes to check out is read from the customer identification means, and the customer data corresponding to the identified customer is read out by the change calculation means and the display output means j. The purchase amount of the customer is inputted sequentially through the purchase amount input means d, and sent to the total purchase amount calculation means f and the display output means j. The total purchase amount calculation means f calculates the total purchase amount by accumulating the purchase amount, and calculates the total purchase amount by the service point calculation means g,
It is sent to the change calculation means and the display output means j. The service point calculating means g calculates a service point by performing calculations according to predetermined conditions based on the total purchase amount, and sends it to the change calculating means.

Further, the deposited amount from the customer is inputted by the deposited amount input means e, and the change calculation means and display output means j
However, when the deposited amount is input, the change calculation means subtracts the fraction of the total purchase amount that is less than or equal to a preset digit from the service points or the service points in the read customer data, and then calculates the remaining amount. The amount is subtracted from the deposited amount to calculate change, and the change is sent to display output means j. Further, the service points after subtracting the fractions and the total of the service points in the customer data are sent to the customer data updating means i, and the customer data updating means i uses this as a new service point in the customer data and identifying means. Update the contents of the file. Further, the above-mentioned customer data, purchase amount, total purchase amount, deposit amount, change, etc. are displayed visually or converted into a hard copy by the display output means j each time.

FIG. 4 shows the flow of a program in this system, and the operation of this system will be explained below in accordance with this flow.

A customer who wants to check out products in a shopping cart at a supermarket, etc., first presents the customer card 1 to the clerk. ) and have its magnetic stripe 11 read.

When customer data is input from the magnetic card reading/writing device 2 (step 31), the CPU 9 temporarily stores the customer data in the RAM 7 (step S2), and sends the customer identification number and service points in the customer data to the printer 5. It is printed on a receipt (not shown) (step S3).

Note that the service score in the customer data is rQJ at the beginning, that is, at the time when there are no past purchases.

Next, the store clerk sends the products in the shopping cart one by one to the scanning section of the barcode scanner 10 and registers the products by having the barcode read or by inputting the price from the keyboard 3 ( Step S4).

If the input barcode is the product number, the CPU9
Read the price of the corresponding product from the auxiliary storage device 8 (Step S5), temporarily store it in the RAM 7 and display it on the display 4, then drive the printer 5 to print it on the receipt, and print it for each product. Repeat (step S6
), and the price of the product input via the keyboard 3 is handled in the same way.

When the input of prices for all products is completed, the clerk operates the subtotal key on the keyboard 3 to instruct calculation of the total purchase price.

The CPU 9 receives and accepts the command (step S7), and then R
The total price of all the products stored in AM7 is calculated and stored, and this is displayed on the display 4 and printed on the receipt via the printer 5 (step S8).
The PU 9 calculates and stores service points according to preset service conditions based on the total purchase amount, and prints them on the receipt via the printer 5 (step S9
).

Furthermore, when the customer pays for the total purchase amount displayed on the display 4, the clerk records the deposited amount on the keyboard 3.
Enter more information.

The CPU 9 receives the deposited amount (step 51).
0), this is stored at - time and displayed on the display 4, and is also printed on the receipt via the printer 5 in step 311.
), and also performs the following change processing,! II. Fraction below a preset digit of the total purchase amount, here 1
The amount less than 0 yen is deducted from the calculated service points or the service points in the customer data, the remaining amount is deducted from the deposited amount, and this is displayed on the display 4 and printed on the receipt via the printer 5. (Step 12).

Furthermore, the CPU 9 totals the service points after subtracting the fraction and the service points in the customer data, and uses this as the new service point in the customer data to update the data in the magnetic stripe of the customer card by the magnetic card reading/writing device 2. At the same time, it is printed on the receipt via the printer 5 (step 313).

The clerk refunds to the customer the change displayed on the display 4 that is less than 10 yen, and returns the customer card 1.

In addition, if the total of the calculated service points and the service points in the customer data is less than a fraction of the total purchase amount, in principle, the change including the fraction will be refunded, but by carrying the fraction into the service points. You can also choose not to handle fractions even when it is necessary.

In the above embodiment, the customer identification number and the service score are recorded on the magnetic card, but a well-known IC card or the like may also be used.Although it varies depending on the type of purchase and service conditions, the service score can be recorded on the magnetic card. If it is used only to process rounded numbers, the number of boat fishing will increase, so check the service points regularly, and if it exceeds a certain amount, part of it will be given to the customer as a service ticket (discount ticket). You may also issue it.

〔Effect of the invention〕

As explained above, according to the present invention, fractions of change are processed based on the customer's purchase type (service points), so it is possible to prevent checkout work from becoming complicated and time-consuming. Moreover, there is no need to burden customers or retailers with up-front investment costs (and even if an accident occurs, the damage is limited to a small amount of service points, and there is no need for special hardware or lines). Since it is not an essential element, it has the advantage that the system can be provided at a low cost.

Additionally, since customer data is recorded on magnetic cards,
Another advantage is that the same customer card can be used at other stores.
