Abstract

PURPOSE:To make the business of a shop highly efficient and to return a merit on a shop side to customers in the form of money by designating a change fraction and depositing it as information. CONSTITUTION:In customer information 41 provided on a file 4 in a POS terminal device 10, areas, which respectively designate the number of the digits of the change inputted to change deposit, the rate of interest to be inputted, and the amount of a note issued when the change deposit amount to a prescribed level, are provided in addition to a change deposit area. Further the fraction of the change generated at the time of registering payment is eliminated because the number of the digits designated by the change fraction digit number is subtracted, the subtracted fraction is multiplied by the designated rate of the interest, inputted to the change deposit, and when the cumulative amount exceeds the designated amount of the note, the amount of the note is subtracted from the change deposit, and simultaneously the note is issued. Thus the shop merit can be returned to the customers.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is directed to a POS (Point of 5ale)
) This relates to a terminal device that improves the payment method, converts fractions of change into electronic information and processes it, and can also be used for managing total sales.

(Prior Art) Regarding the improvement of the change payment method in a POS terminal device, as described in Japanese Patent Application Laid-Open No. 62-269291, it is proposed to “read the change data from the previous shopping from the customer's card,
The amount to be paid by the customer is calculated by subtracting the change data from the total purchase amount data, the amount to be paid by the customer is subtracted from the deposit amount from the customer to calculate the amount of change, and the amount is determined in advance from the amount of change. The remaining amount is calculated by subtracting the amount that can be paid out, and the remaining amount is written to the card as change data.

According to the bulletin, it eliminates the need for store owners to prepare change before opening and check change after store closing, and it frees customers from the hassle of carrying around change, but at the same time, the following problems are included and improvements are needed: There was a need for

(1) On the store side, it saves change preparation/inspection and handling of small change, which improves operational efficiency and provides financial benefits, but for customers, the above benefits are only eliminated by eliminating the hassle of carrying change There is no refund.

(2) Change is magnetically written into the magnetic card and printed on the card, so if the card is lost, there will be a financial loss for the customer and at the same time the amount lost will be unknown. cormorant.

(3) A writing machine is required to write change information on the card, which increases the cost of the device.

(4) Since change information is not managed cumulatively, the total sales and cash balance in the - period do not match.

Further, since the general POS terminal does not perform cumulative management of deposits, it is necessary to perform cumulative management of the above-mentioned similar amounts and change amounts to properly manage total sales.

(5) Shopping customers feel uneasy because there is no indication of the fixed amount to be paid to the customer.

[Problem to be solved by the invention]

The above conventional technology lacks consideration in terms of returning benefits to consumer customers, guarantees, and sales management, and there is no monetary return to customers of the store's benefits gained through improved business efficiency, and there is no loss of credit when the card is lost. There was a problem that the amount of loss was unknown due to the occurrence of a loss, and that the total sales and the amount of cash in stock did not match.

SUMMARY OF THE INVENTION An object of the present invention is to provide an inexpensive POS terminal device that solves the problems of the prior art described above and can return store benefits to customers.

Another object of the present invention is to provide a POS terminal that can prevent financial loss due to card loss, easily provide customers' financial information at all times, and clarify the amount to be guaranteed even if the POS terminal itself malfunctions. The goal is to provide equipment.

Still another object of the present invention is to provide a POS terminal device that can accurately manage and grasp total sales.

[Means to solve the problem]

In order to achieve the above object, the present invention provides customer information on a file within the POS terminal device, provides an area within the information to store the total number of change fractions at the time of payment registration, and uses this area for change deposit management. By accumulating a certain amount of interest and issuing cash vouchers that can be used as payment media when the amount of change deposited exceeds a certain amount, we eliminate the hassle of dealing with small change and small change. The benefits obtained are returned to customers in the form of interest on change.

Furthermore, even if the customer loses the card, the change deposit is left as information in the POS device, so it is irrelevant, and the change deposit amount and the above-mentioned voucher amount can be printed on the receipt by the printing unit originally equipped with the POS terminal device. By printing out the amount, the customer can easily know the amount, and even if the POS terminal device malfunctions and the information disappears, the receipt can be used to guarantee loss.

According to the above method, since the customer card only needs to read the customer number, only a reading device is required, and it can be realized at low cost for a device that requires both reading and writing.

In order to further achieve other objects, the present invention provides PO
By providing sales information on the S device file and managing and storing the total sales (total sales), total cash deposits, total cash change, total cash vouchers, and total change deposits within the same information, Ensured that there were no inconsistencies in total sales and inventory management.

[Effect]

Customer information provided on the file in the POS terminal device includes:
In addition to the change deposit area, the number of digits of change to be put into the change deposit,
It has an area for specifying the interest rate to be transferred and the amount of cash vouchers to be issued when the change deposit exceeds a certain amount, and the fraction of change generated at the time of payment registration is the number of digits specified in the number of digits of change fraction. When the change is deducted, there are no more fractions of change, and the deducted fraction is multiplied by the specified interest rate and transferred to the change deposit, and when the cumulative amount exceeds the specified cash voucher type, a cash voucher is issued with the same amount as the deduction from the change deposit. It works like this.

The amount of change in the deposit and the coupons are printed out on the receipt along with the sales and payment information.

The sales information provided on the file within the POS terminal device includes an area for managing various totals for a certain period of time, including the total sales amount, cash deposit amount, and cash deposit amount.

Each time the amount of cash change and the amount of issued coupons is generated, the cumulative total is added to the corresponding area in the management area, and the total sales for a certain period can be calculated correctly by calculating the total amount of each of the above. You will be able to understand it.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS. 1 to 16.

Figure 4 shows a P with a change function, which is the first object of the present invention.

), and each component is connected to the CPU 1 via a CPU bus BUS.

FIG. 5 shows the configuration of each area in the customer information 31.41 stored and managed in the file 4 and memory 3, including an ID section that stores the customer number, and the cumulative total of the customer's past purchases over a certain period of time. ΣP, ΣN section 1 that stores the cumulative number of purchased points
The most characteristic information of the present invention is a change deposit 88 section that stores the cumulative fractional amount of change over a certain period of time, an r section that stores the interest rate of the change deposit, and a fixed amount of change deposit balance including interest. Section and W section to store the amount of coupon issued or cash coupon issued when exceeding the amount, change deposit 8
The customer information 31 and 41 are comprised of the Q section and other information areas that store the fractional digits of change to be transferred to the 8th section.

FIG. 1 is an example of an operation flowchart for realizing the change deposit function of the present invention using the device configuration shown in FIG. 4 and the customer information shown in FIG. It is controlled as described in the following embodiment by the operator's operations and the program stored in the memory 2.

#n (
n = number) indicates the order of the flowchart, and the P attached to the right side
, ID, and other symbols indicate information handled by the box.

#1 to #5 in the flowchart are operations or operations in the sales registration stator, which register the amount of products purchased by the customer and calculate the total sales.

#6 to #21 are operations or operations in the payment registration status, in which the customer pays the amount equivalent to the total sales with cash or a coupon that is a feature of this patent, change is processed, and a fraction of the change is is deposited, a coupon is issued, and finally cash change and a receipt with the amount of change deposited and the amount of the coupon printed are given to the customer, completing a series of sales/payment registrations.

When the sales registration is started (#1), the operator registers the products purchased by the customer (inputs the price, etc.) using the keyboard 6 (#2).

The input data such as the amount is temporarily stored in the input/output information area 33 of the memory 31 and displayed/printed on the display 5 and printer. (Unless otherwise specified, the display means the display on the display 5, and the printing means the printing on the printer.) If there are multiple registered products (Registration completion judgment (
#3) = NO) If the sales registration (#2) is continued and the final product is registered (registration completion judgment (#3) = YE
S) calculates the sales total P from the amount of each product stored in the input/output information area 33 by pressing the subtotal key (function key on the keyboard 6, not shown) by the operator #4) and displays/ Print (#5).

The above is the sales registration operation (#1 to #5), and the following is the payment registration operation (#6 to #21).

At the beginning of payment registration, the customer confirms the sales total P, and then hands over the card 8A on which the customer number is stored to the operator in order to use the change deposit system.

When the operator reads the customer number ID with the card reader 8 (#6), the customer number ID is displayed in the input/output information area 33.
Information that matches the same ID (customer number ID) is temporarily stored in
, total purchases ΣP, total number of purchases ΣN, change deposit ΣS, interest rate r, coupon issue amount, cash ticket issue amount M, number of fractional change digits Q, etc.) from the customer information 41 of file 4 to the customer information area of memory 3 31 (#7),
Among these pieces of information, the amount of change deposit ΣS is displayed on the display 5 together with the sales total P (#7).

If the customer does not use the coupon described below as a payment medium, the operator should check the sales total P and input the cash amount M paid by the customer as cash from the keyboard 6 #1
1) Change C+c based on the cash deposit amount M inputted and temporarily stored in the input/output information area 33 and the sales total P
=Cash M-Sales total P is calculated and displayed on the display 5 together with cash M (#11).

If a customer uses a coupon, which will be described later, as a payment medium, the process will be as follows.

The operator receives the coupon from the customer and inputs the amount K from the keyboard 6 (#8).

Before entering the coupon amount, normally use keyboard 6.
The upper coupon key (function key, not shown) is pressed.

The input coupon amount is temporarily stored in the input/output information area 33, and the remaining payment amount (PK) is calculated by subtracting the coupon amount from the sales total P (#9), and the coupon amount is displayed/printed. The payment balance is only displayed (#
10).

Therefore, the calculation of change C+C' after inputting cash type M (#11) is performed by C+c =M-(PK), and as can be seen from the same size displayed on display 5 (#11), If you do not use a coupon, then = O, so C+
c'=MP, which is the same as the change calculation formula described above.

Here, C' indicates a fraction of the change, which is separated from the amount of the change calculation M-P or M-(PK) by the number of digits specified by the number of digits Q of the change fraction, and the same fraction of change. Let C' be deposited into change deposit ΣS.

Next, the change fraction C' is multiplied by the rate specified by the interest rate r, and the change deposit ΣS is added and updated (011)
.

That is, read the change deposit ΣS, add c'Xr to it, and write it to the change deposit ΣS again (ΣS=ΣS+c'Xr).
.

Change deposit ΣS to ensure that interest calculation is not disadvantageous to customers
The interest transfer calculation value c'Xr is managed to one or two decimal places, and when displayed or printed, one decimal place is rounded off and displayed in yen.

After updating the change deposit as described above, the interest-bearing change fraction c
'Xr and the cash change C after subtracting the fraction are displayed separately (#13) L, the customer has cash change C and change deposit ΣS
Make sure that you know how much the deposit amount c'Xr is.

Next, it is determined whether to issue a coupon ticket or a cash ticket based on the updated amount of change deposit ΣS, and if the conditions are met, either one will be issued.

First, the coupon issuance amount and the cash coupon issuance amount W in the customer information 31 are read out and checked, and the issuance operation for whichever amount is specified is performed.

That is, if the cash ticket issue amount W is specified as O yen, a coupon is issued, and if the coupon issue amount = 0 yen, a cash ticket is issued.

FIG. 1 shows an example of coupon issuance.

Compare the updated amount of change deposit ΣS with the specified coupon issue amount K. #14) If ΣS≧, then (
#14: YES), debit the coupon issued amount K from the change deposit ΣS, calculate the total change deposit balance, and change the change deposit 2.
Update part 8 (#15.ΣS=Σ5-K).

After completing all of the above calculations, change deposit information (initial change deposit amount ΣS, interest-bearing change fraction C'Xr',
Print/display the change balance ΣS) after the coupon has been withdrawn (#15), and finally display it on the coupon and print and issue the coupon on the receipt using a printer (#17).

Judgment that the amount of change deposit ΣS≧coupon issued amount (#
If 14) is No, display/print the change deposit information (initial change deposit balance ΣS, interest-bearing change fraction c′Xr, change deposit balance after transfer ΣS) on the display 5 and printer 7. However, coupons will not be issued.

Information such as the cumulative purchase total K and the cumulative purchase points ΣN in the customer information 31 is updated as appropriate after the customer number ID is read (#6) until the same information is saved in the corresponding area of the file 4 again.

Customer information (cumulative purchase total ΣP) updated as above.

Cumulative number of purchased points ΣN, change deposit ΣS, interest rate r, coupon issue amount K, cash coupon issue amount M, and number of fractional change digits Ω
etc.) from the customer information area 31 of the memory 3, the customer number I

Save (#19) At the end of the payment registration status,
The operator of the POS terminal device 1o hands the customer a receipt with change information and a printed coupon, and cash change (#20), and ends the payment registration status (#21).

Figures 7 and 81ii! 1 indicates an example of information displayed/printed according to the flowchart shown in FIG.

#n (n = number) added to the left of each display and printing example is the first
This corresponds to the order of the flow chart in the figure.

First, the sales total display/print (#5) in FIG. 1 is displayed/printed as shown below.

Display Showkei 2,345 Prints Total ¥2,345 This example shows that the customer's shopping total, that is, the total sales P, is ¥2,345.

The numbers in each area in Figure 5 are the numbers that can be read from the customer number ID (
An example of each piece of information loaded into the customer information area 31 of the memory 3 by #6) is shown.

It is as follows.

Customer number ID 88081912 Cumulative purchase ΣP
31210 cumulative purchase points ΣN
156 Change deposit ΣS 98
．． 16 Interest rate r5 Coupon issue amount K 100 Cash coupon issue amount WO Number of digits of change fraction Q1 The above is the information of the customer with customer number ID = 88081912, and the same customer has been in the past for a certain period of time.

Cumulative amount: 31; I have made purchases of 210 yen and a cumulative total of 156 items, and the amount of change deposited from my purchases so far is 98 r.
'J l 6 sen, the customer deposits a 1-digit change fraction into the change deposit, and when the balance exceeds 100 yen, he wishes to issue a coupon, and the store will add interest to the customer as a return of benefits. indicates that the interest rate is 5%.

Since the above is an example of customer information, change deposit balance display (
The display in #7) is as follows.

ID=? ? Tsurisenyokin 98ID=? ? indicates that the customer number ID has been correctly read by the card reader 8. In addition, the displayed amount of Tsurisenyokin is as per 8 above.
Since the value of 8 copies is 98 yen and 16 sen, the value is rounded to the nearest yen and displayed as 98 yen.

When coupon amount K is input and displayed/printed.

(# l O) is displayed/printed as follows: Tsurisen Coupon 100 Zankin
2,245 Print Change Coupon 100 indicates that a 100 yen coupon K has been deposited and the payment balance P- is 2,345 - 100 = 2,245 yen. The payment balance is not printed.

However, if the coupon is not used, the above display/printing will not be done.

If you deposit cash M of 2,500 yen in the above situation (
all) display and printing.

Display Genkin 2,500 otsuri
255 Print Deposit 2,500, which means that 2,500 yen of cash M was deposited and change C+c' was 2,500 - 2,245 = 255 yen.

Display and print of cash change C and interest transfer fraction c'Xr (#13) Genkin 2,500 Otsuri
5+250 Printed Change 5+250 indicates that the cash change C is 250 yen and the interest-bearing change deposit amount c'Xr is 5 yen.

This is because the change fraction digit number Ω specified in the customer information is 1 digit, so the last 1 digit of 5 yen is separated and the cash change C is 255 yen.
Since −5=250 yen and the specified interest rate r is 5%, c′ X r = 5 X l , 05=5.2
5. In other words, since the amount is 5 yen and 25 yen, it is rounded to the nearest 1 yen and the interest-bearing change fraction c'Xr is expressed as 5 yen.

In order to display/print this in an easy-to-understand manner, it is displayed as 5+250.

Furthermore, the display and printing in the display/printing of change deposit information (#18) are shown. Add the current change fraction (with interest) c'Xr = 5.25 yen to the place where was, and get 9.
8.10+5°25=103.35 yen change deposit amount ΣS
However, since a coupon K of 100 yen is issued, the balance is 3 yen and 35 sen, that is, rounded to the nearest yen and displayed as 3 yen.

In the unlikely event that the coupon issue amount does not exceed 100 yen, the display will be printed as 5+65...→70.

In this case, it is assumed that the change deposit amount ΣS is 65 yen.

Display and printing in coupon issue/display (#17) are shown.
It shows that it was issued on August 8, 1988.

When printing the change deposit information (618) and printing the coupon, it is also possible to make the information easier to see by printing dotted lines as shown in FIG.

Figures 9 and 10 show cash change 25 in #13.
Another display/printing method for 0 yen and interest-bearing change fraction 5 yen is shown.

FIG. 9 shows an example of the display. By displaying Otsuri 255 and blinking the last digit of 5 yen, the separate display like 5+250 is unnecessary.

FIG. 10 shows an example of printing, and by printing an underground line on the last digit of change 255, separate printing such as the above-mentioned 5+250 is unnecessary.

In the explanation of the embodiment according to the flowchart shown in FIG. 1, the loading of customer information from the file 4 to the memory 3 and the reverse saving are performed only for information corresponding to the same number when the customer number is read. As mentioned above, at the start/end of work on -day, specific keys or key operations on the keyboard are assigned to load/save customer information, all customer information is expanded in memory, and then stored in memory. The customer information may be updated.

Further, it may be possible to automatically load/save the data after power is turned on or before power is turned off.

FIG. 2 is a flowchart showing an example of cash ticket issuance in place of the coupon ticket issuance in the flowchart of FIG.

Cash coupons are refundable cash of the same amount as the same amount separately from cash change at the time of payment registration, and when issuing cash coupons, it is not possible to use coupons as payment media, so please refer to Figure 1. Enter the coupon amount (#8
・), calculation on payment balance P- (#9), display/printing on coupon amount, and display on payment balance P- (#10) are eliminated, and change deposit ΣS ≧ coupon issue amount is determined (
#14) The subsequent operations are replaced with those shown in FIG.

In other words, after confirming =O to the coupon issued amount, add the interest-bearing change fraction c'Xr and compare the updated change deposit ΣS with the cash coupon issued amount W in the customer information #1
4) If ΣS≧W, the cash vouchers W are withdrawn from the change deposit ΣS, the balance is calculated, and the change deposit ΣS is calculated.
(#15).

The subsequent printing/display of the change deposit information (#16) is the same as in the case of issuing the coupon described above.

Finally, display the cash ticket amount W and print the cash ticket on the receipt using the printer and issue it (#17
).

The change deposit amount ΣS is compared with the issued cash ticket amount W (#14), and when ΣS is less than W, the change information is displayed/printed in the same manner as in the case of issuing a coupon as described above.

The updated customer information is saved from the customer information area 31 of the memory 3 to the corresponding area 41 of the file 4 (#19), as in the case of coupon issuance described above, and the operator hands over cash change and a receipt to the customer.

If a cash ticket has been issued on the receipt, the corresponding amount of cash is refunded to the customer and the series of sales/payment registration operations is completed (#21).

FIGS. 11 and 12 are examples of display and printing in the case of cash ticket sales, and correspond to FIGS. 7 and 8 in the case of coupon ticket issuance.

The difference between Figures 11 and 12 from Figures 7 and 8 is that #10 is no longer displayed/printed because there are no more coupons to hold, and the display and printing when cash coupons are issued are as follows. That's a thing.

Display Cash back 100 printed Cash back ¥100 SA store 88-8-8 In other words, both the display and print indicate that 100 yen will be refunded in cash from the change deposit (cash back), and the print also shows the store name and date of issue. is also printed.

FIG. 6 shows the contents of sales information managed within the POS terminal device in order to realize the sales management function which is the second object of the present invention.

The POS terminal device has the same configuration as that shown in FIG. 4, and has nine areas 42 and 32 on the file 4 and memory 3 for storing, managing, and updating sales information.

The sales information is normally loaded from file 4 to memory 3 when the power is turned on or when opening the store to start sales operations, and is saved from memory 3 to file 4 when opening operations or the power is turned off when sales operations are completed. Keep it.

The sales information 32.42 consists of the following management areas, and these areas are arranged in the order of lower g in Figures 1 and 2 (
#n) is updated.

Area Management details Update period ΣP Total sales #4 ΣM Total cash deposits #11 ΣK Total coupon deposits #8 ΣC1! Total change #11 ΣC' Total change deposits #11 ΣW Total cash #17 Total sales ΣP is an area that manages the cumulative total of sales in a certain period, and the total sales P calculation in Figure 1 (#4)
This area will be updated from time to time.

The cash deposit total ΣM is an area for managing the cumulative total of cash deposited by customers, and this area is added and updated when the cash amount M is input (#11) in FIG.

The coupon total amount Σ is an area for managing the cumulative total of coupons deposited by customers as payment media, and is added and updated when the coupon amount in FIG. 1 is input (#8).

The total cash change ΣC and the total change deposit ΣC' are.

This is an area that manages the cumulative total of change paid to customers in cash and the cumulative total of fractional change transferred to the change deposit (without interest), and is added and updated when calculating change C + c'(#11) in Figure 1. .

The cash total ΣW is an area for managing the cumulative amount of cash paid back to the customer in cash at the time of cash ticket issuance, and is added and updated at the time of cash ticket issuance (#17) in FIG. 2.

As mentioned above, since the cumulative total of each deposit and withdrawal amount in sales/payment registration is managed, it is possible to accurately understand the total sales for a certain period by performing the following calculations. can.

Total sales (total sales) Σp = (Total cash deposits ΣP + Total coupon deposits ΣK) - (Total cash change ΣC Total ten change deposits Σ
C'+cash total ΣW)...First equation FIG. 13 shows an embodiment in which the change deposit function described above is applied to a system including a POS terminal device, a higher-level control device, a store processor, or a host computer.

The POS terminal device 10 is the same as that shown in FIG. 4, but in this example, a case will be explained in which the file 4 is not included.

The controller 20 connects the POS terminal device 1 to the POS terminal device 1 via a communication line.
0, and has a file 24 in which an area 24 of information corresponding to customer information 31 and sales information 32 on the memory 3 in the POS terminal device 10 is stored.
1 and 242 for the maximum number of PO3?1iIj9111 units.

The store processor or host processor 30 is a processor installed in a store to manage information in the store or a processor installed in a central calculation center to manage information in all stores. The file 34 has management areas for customer information 341 and sales information 342 for the maximum number of POS control units in all stores, and the controller 2
is connected to.

In this system, in order to realize the change deposit function described above, instead of loading the customer information 41 from the file 4 (#6) in FIGS. accesses the store processor/host processor 30 and files 24 or 34.
Customer information 241 or 341 in POS terminal v! 1
Load it into memory 3 of 10.

Also, instead of saving the updated customer information 31 to file 4 (#19) in FIGS.
The host processor 30 is accessed and the updated customer information on the memory 3 of the POS terminal device 10 is saved in the customer information 241 or 341 in the file 24 or 34.

Figure 3 shows the steps added to the flowchart in Figure 1 or Figure 2 to load/save customer information in the above system. After (#6), the same customer number ID is sent (#6-1) and customer information (ID, ΣP, ΣN, ΣS,
r, ni, w.

The reception (#6-2) operation of Q) is performed using the communication adapter 9 in Fig. 4.
The customer information load (#
7).

Also, updated customer information (ID, ΣP, ΣN).

ΣS, r, W, R) are transmitted via the communication adapter 9 during the customer information save (#19) operation in FIG.
Saving is realized by transmitting to the customer information area 241, 341 on the file 24 or 34 of the controller 20 or store processor/host processor 30 (#19).

In addition, in order to realize the sales management function described above, the sales information area 32 of the POS terminal device 10 and the sales information areas 242, 342 of the controller 20 or store processor/host processor 3o must be connected at the start and end of the business. All you have to do is load and save at the appropriate timing.

If save/load is implemented as described above, other functions can be implemented as explained in FIGS. 1 to 12.

Although the POS terminal device 10 in FIG. 13 has been described as having no files, it may of course have files.
The first step is to transmit and receive customer information and sales information between files in the controller 20 or store processor/host processor 30 and files in the POS terminal device 10, and to load/save information into the memory 3 of the POS terminal device 10.
This may be done from the refile 4 explained in FIGS.

If the host processor 30 in FIG. 13 is a processor of a bank calculation center, the file 34 is a file for managing accounts, and the customer information 341 is the customer's account information, the second
In the figure, when the receipt change is given after the cash ticket issuance (#17) (#20), the cash equivalent to the cash ticket is not refunded, but when the customer information is sent (#19) in Figure 3.
), add the cash ticket issuance information and send it.
If the bank host processor 30 side transfers the amount equivalent to the cash voucher to the account in the customer information 341, the bank P can not only withdraw the purchase amount from the account but also deposit change.
OS can be realized.

However, in the cash ticket issuing example shown in FIG. 12, it is necessary to display that the money has been transferred to the bank as shown below.

Cashback (BANK Furikomi) ¥100 SA Shokai 88-8-8 Figure 14 shows customer information required for the change deposit function.

An example of an operation flowchart for realizing a method of setting and modifying preset information, Figures 15 and 16 show the corresponding display 45.
This is an example of display and printing by the printer 7.

After starting the setting operation (# l O1), the operator presses the control switch (not shown) on the keyboard 6 to
Set the OS terminal device 10 to “setting” mode (#10
3).

A control switch is normally provided in a POS terminal device, and in addition to the "setting" mode, it can also be used in the "registration" mode, which performs the sales/payment registration mentioned above, and the "inspection j mode," which checks the sales status over a certain period of time. Switching settings can be made using a key.

The operation in the "r setting" mode is normally performed by an administrator, but for the sake of simplicity, it will be described here as an operator as described above.

Next, the operator causes the card reader 8 to read the card 8A with the special number registered (#103), and the program on the memory 2 identifies this.

At the same time as temporarily storing it in the input/output information area 33, all the customer information 41 on the file 4 is loaded into the area 31 on the memory 3 in the format shown in FIG. 5 (#104), and the preset information of the customer with the youngest customer number ID is is displayed as shown in FIG. 15 (#105).

ID = 12345678 r = 5 = 100 M = OΩ = 1 This display allows the customer with customer number ID = 1234567 to put the last 1 digit of the change fraction (JR = 1) into the change deposit,
I would like to issue a 100 yen coupon (K=lOO, W=0
), and the store's interest rate for the same customer is 5% (
r=5).

Now, the operator is informed of which part of the preset information should be corrected by a blinking display, and in this state, by pressing the numeric keys (numeric keys such as 0 to 9.00) on the keyboard 6, , the key value is entered at the character position that was blinking.

Blinking advances to the next character position.

For example, in FIG. 15, when "1" of M=100 is blinking, [If you press number key 2, M=2
00 and Blink moves to the next character position after 2.

The blink position can be moved to the desired character position using a specific key on the keyboard (for example, the numeric key "00'"), and the operator can modify the required preset information from the keyboard 6 as necessary (#106). ).

l When you finish modifying the customer's preset information, press keyboard 6.
By pressing the other key above, the primary customer information is called up on the display 5 and the same correction as above is made (#108
No. → #105 → #106) The modification of preset information for all customers that requires modification has been completed (# l Y of O8
ES) Then, the operator presses a specific key on the keyboard 6 to print all the corrected preset information on the receipt on the printer.

The program on the memory 2 recognizes the specific key and prints out the corrected preset information of the customer information 31 on the memory 3 as shown in FIG.

According to FIG. 16, the customer with ID=12345678 is
A 200 yen coupon is issued when the change fraction is specified as one digit (Q = 1) (K = 200.W = O), the interest rate is preset specified as 5% (r = 5), and the customer with ID = 22345678 specifies the change fraction. is 2 digits (1=2), a 500 yen cash ticket is issued (K=0, W=500), and the interest rate is preset at 6%.

Finally, by pressing a specific key on the keyboard 6.

The program on memory 2 stores all customer information 31 on memory 3.
Save in the relevant area on file 4 (#109)
The setting operation ends (#111).

In the example shown in FIG. 14, the customer information is stored in the file 4 in the POS terminal device 10, but if the method described in FIG. Even if there is customer information in the file, it is easy to infer that the information can be set and modified.

According to the above description, the file device 4 in the POS device 10 stores and manages customer information and sales information.

In addition to fixed disk devices and flexible disk devices, we also offer memory cards with battery backup to ensure non-volatility of information, and rewritable E"FROM.

It is easily inferred that a memory system such as bubble memory can also be substituted.

〔Effect of the invention〕

Since the present invention is configured and operated as described above, it produces the effects described below.

1. By specifying the fractional amount of change and depositing it as information, stores no longer have to prepare and handle change (1 yen, 5 yen), which is the most troublesome part of shopping, which improves business efficiency for stores. This saves the customer the trouble of carrying coins around, and at the same time, by allowing interest to be earned on change deposits, the store can return the benefits to the customer in the form of money.

2. Since the change deposit is stored and stored in a file within the POS terminal device or system, even if the customer loses the card, there is no financial loss and it is very safe.

3. Easily send change and coupons using the printer that the POS terminal is equipped with.

Cash vouchers can be issued, customers can easily check them, and there is no need to worry about the amount of money being left unknown due to card loss or equipment failure.

4. This function can be realized at low cost since only a card reader is required to read the customer card and no card writer is required.

5.To manage total sales, in addition to managing the cumulative total of cash deposits and cash change, the cumulative total of coupon deposits, change deposits, and cash payments is also managed, so sales information can be managed accurately.
