Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to an electronic cash register (hereinafter referred to as ECR).
In particular, it relates to an ECR that processes change using a change card as an intermediary.

[Summary of the Invention] In order to save time and effort in processing change, the present invention issues a change card, records the cumulative amount of change on this change card, and allows payment to be made using this change card.

[Prior Art] Some conventional ECRs have a function of calculating and displaying the amount of change, but there is no one that can automate change processing. Therefore, in the past, all change processing was done manually.

[Problems to be Solved by the Invention] As described above, in the past, all change processing was done manually, so the operator had to hand over the change to the customer one by one. However, since some products (particularly food items sold at supermarkets) are traded at prices down to 1 yen, change is inevitably small. As a result, it takes time for the operator to exchange change, slowing down the processing speed, and there is a problem in that a large amount of small change accumulates in the customer's wallet. Moreover, it was very troublesome to have to prepare a large number of small denomination coins such as 1 yen coins and 5 yen coins in each ECR for change.

Therefore, it is an object of the present invention to provide an ECR that can overcome the above-mentioned shortcomings.

Means for Solving Problem F] The present invention comprises: a card issuing means for issuing a change card on which the amount of change to be paid to a customer is recorded; a card payment selection means for selecting a payment using the change card; A balance reading means for reading the balance of change recorded on the change card; a balance rewriting means for rewriting the balance of change recorded on the change card; and a balance reading means for reading the balance of the change recorded on the change card; A first determining means for determining whether the amount is greater than the total transaction amount, and a second determining means for determining whether the amount of change to be paid to the customer is less than or equal to a predetermined amount.
When it is determined that the balance on the change card is smaller than the total amount of change at that time, and it is determined that the amount of change to be paid to the customer is less than a predetermined amount, When payment is not selected and it is determined that the amount of change to be paid to the customer is less than a predetermined amount, the change amount to be paid to the customer at that time is added to the balance of the change card. If payment using a change card is selected and the balance on the change card is determined to be larger than the total transaction amount at that time, the transaction will be discounted at a discount rate according to the balance on the change card. Calculate the total amount and get this calculated discount! The balance of the change card is rewritten so that the total amount of transactions No. 1 is deducted from the balance of the change card.

[Operation 1] In this invention, the card issuing means issues a change card instead of paying change to the customer. The balance rewriting means rewrites the balance of the change card when a predetermined condition is met, thereby enabling automation of change processing and payment using the change card.

[Embodiment] FIG. 2 is a schematic block diagram showing an embodiment of the present invention. In the figure, a CPU 1 includes a memory 2, a display 3.
A printer 4 and a keyboard 5 are connected. memory 2
stores an operating program for the CPU 1 as shown in FIG. 1, for example, and also stores various data necessary for data processing by the CPU 1. Data of particular interest to this example include areas 2a, 2b and 2c of memory 2.
Discount rates α, β, and γ are stored in . The display 3 is for displaying the input price of the product, the amount of change, etc. In addition, the CPU has a card reader/writer 6.
and a card issuing machine 7 are connected. The card reader/writer 6 is for reading the balance from the change card and rewriting the balance of the change recorded on the change card. The card issuing machine 7 is a device 6-1 for issuing change cards. Here, the change card is constituted by, for example, a magnetic card whose data can be rewritten, and records the amount of change to be paid to the customer.

FIG. 3 is a diagram showing an example of the key arrangement of the keyboard 5 shown in FIG. 2. In the figure, the keyboard 5 has FOR
A mode key 51 for switching the operation mode, a numeric keypad 52 for inputting numerical information, various function keys 53, and a department key 54 for inputting a department code are provided. The function keys 53 include lock keys such as a sell key 53a and a cash key 53b, as well as a card issuing key 53c and a card payment key 53d, which are of interest to the present invention. This card issue key 530 is a key for indicating issuance of a change card, and the card payment key 53d is a key for selecting payment using a change card.

FIG. 1 is a flowchart for explaining the operation of the CPU 1 shown in FIG. The operation of the above embodiment will be explained below with reference to FIG. First, steps 81-S
3, a registration process is performed, and the total amount is displayed by operating a close key (sell key 538, cash key 53b, etc.). These operations are similar to conventional ECR. next,
In step S4, it is determined whether the change card has been input (inserted) into the card reader 6 or not. If the change card has not been input to the card reader 6, the process proceeds to step S5, where the operator is made to input the deposited amount from the customer, and the change is calculated and displayed on the display 3 in step S6. Subsequently, the process advances to step S7, where it is determined whether the card issue key 53C has been pressed. If the card issue key 53C is not pressed, step S
Proceeding to step 8, the operator is made to accept and hand over the change as usual. On the other hand, if the card issue key 53C is pressed, the process proceeds to step $9, and it is determined whether the amount of change is less than a predetermined amount. Only when the amount of change is less than a predetermined amount, the process proceeds to step S10, and the card issuing machine 7 issues a change card recording the amount of change at that time. Incidentally, when the amount of change is more than a predetermined amount, the operator is made to receive and hand over the change in step S8 as in the conventional case. in this way,
The decision to determine whether or not to issue a change card based on the size of the change was made considering that in the case of an extremely large amount of change, the customer would prefer to receive the change in cash. It is something. In addition, as will be described later, in this example, the discount rate is changed depending on the balance on the change card, so if this kind of discrimination is not performed, the customer will not be able to get a large discount with as few transactions as possible. This is because even when purchasing products of small value for the purpose of purchasing goods, they tend to pay with high-value banknotes.

On the other hand, if a change card is input to the card reader/writer 6, the determination in step S4 is rYEsJ, and the process proceeds to step 811. In this step S11, the balance on the change card is read and it is determined whether or not it is equal to or greater than the total sales amount. If the balance on the change card is less than the total sales amount, the operator is made to receive cash from the customer and input the deposit amount in step S12. Then, in step 813, change is calculated and displayed on the display 3. Next, the process proceeds to step 814, where it is determined whether the amount of change is less than or equal to a predetermined amount. If the amount of change is more than the predetermined amount, as in the case of step $9 above,
At step $8, the operator is made to accept and hand over the change. On the other hand, if the amount of change is less than the predetermined amount, step 8
15, the balance of the change card is rewritten by the card reader/writer 6. That is, the card reader/writer 6 rewrites the balance so that the amount of change calculated at that time is added to the balance. The reason why it is determined whether or not to rewrite the balance on the change card according to the amount of change is based on the same determination as in step S9 described above.

On the other hand, if the balance on the change card is greater than or equal to the total sales amount,
The determination at step 811 described above is rYEsJ, and the process proceeds to step 16. In this step 816, it is determined whether the card payment key 536 has been pressed. If the card payment key 53d is not pressed ( ), the process advances to step 812 and the above-described operation is performed. On the other hand, if the card payment key 53d is pressed, step 8
17, it is determined whether the balance on the change card exceeds 10,000 yen. If the balance on the change card exceeds 10,000 yen, the process proceeds to step 818, where the discount rate α is read from area 2a of memory 2.

On the other hand, if the balance on your change card does not exceed 10,000 yen,
Proceeding to step 819, it is determined whether the balance on the change card exceeds 5,000 yen. If the balance on the change card exceeds 5,000 yen, that is, the balance is 5,000 yen or more.
If it is less than 10,000 yen, the process advances to step S20, and the discount rate β is read from the area 2h of the memory 2. On the other hand, if the balance on the change card does not exceed 5,000 yen, step 821
Then, the discount rate γ is read out from the rear 2c of the memory 2. After the discount rate is read in any one of steps 818, 820, and 821, the process proceeds to step S22, where payment is made using a change card.

That is, the total amount of sales is multiplied by the discount rate read in any of the above steps to calculate the total amount of sales after discount. Then, the card reader/writer 6 rewrites the balance of the change card so that the total sales amount after discount is subtracted from the balance of the change card. Note that the discount rate is, for example, α=0.8. β=0.9. γ=0
．． 95, and is configured such that the larger the balance on the change card, the larger the discount amount.

In addition, in the above-mentioned embodiment, the discount rate was changed by dividing the balance of the change card into 10,000 yen and 5,000 yen.
This is just one example, and the invention is not limited to such amounts. Further, in this embodiment, the discount rate is changed in three stages, but the discount rate may be changed more finely.

[Effect of the invention 1 As described above, according to the present invention, a change card is issued instead of handing change to the customer, and the amount of change is cumulatively recorded on the change card, so that the operator can There are fewer opportunities to hand over change, and the burden on the operator can be significantly reduced.

This not only speeds up operator processing, but also
It also saves the trouble of preparing a large number of coins for change in advance. In addition, when paying with a change card, the discount rate changes depending on the balance on the change card, so customers increasingly want to process change with a change card, which reduces the chances of giving and receiving change. I can do it.
