Further, the card reader/writer 25 charges a monetary value to the card C that is in contact with or is held over the card placement section 25a (additionally stores a new monetary value in addition to the monetary value stored in the card). do.

The code reader 27 is, for example, a handy type code reader. The code reader 27 uses, for example, visible light to image and read a symbol attached to a product. Note that the code reader 27 may read the symbols using an optical scanner.

Next, the hardware configuration of the POS terminal 1 will be explained. FIG. 2 is a block diagram showing the hardware configuration of the POS terminal 1. As shown in FIG. As shown in FIG. 2, the POS terminal 1 includes a CPU (Central Processing Unit) 11, a ROM (Read Only Memory) 12, a RAM (Random Access Memory) 13, a memory section 14, and the like. The CPU 11 is the main control body. The ROM 12 stores various programs. The RAM 13 stores programs and various data. The memory unit 14 stores various programs. The CPU 11, ROM 12, RAM 13, and memory section 14 are connected to each other via a bus 15. The CPU 11, ROM 12, and RAM 13 constitute a control unit 100. That is, the control unit 100 executes control processing related to the POS terminal 1, which will be described later, by the CPU 11 operating according to a control program stored in the ROM 12 or the memory unit 14 and developed in the RAM 13.

The RAM 13 includes a product information section 131. The product information section 131 stores product information (product name, product price, etc.) of the product for which sales registration has been processed based on the product code obtained by analyzing the symbol read by the code reader 27 and the total price including tax (purchase amount). ).

The memory unit 14 is composed of a nonvolatile memory such as an HDD (Hard Disc Drive) or a flash memory that retains stored information even when the power is turned off. The memory unit 14 includes a control program unit 141 and a product master 142. The control program section 141 stores a control program for controlling the POS terminal 1. The product master 142 stores product information (product name, unit price, etc.) related to each product.

Further, the control section 100 is connected to an operation section 21, an operator display section 22, a customer display section 23, a printing section 24, a card reader/writer 25, and a code reader 27 via a bus 15 and a controller 16. The controller 16 receives instructions from the control section 100 and controls the operation section 21 , the operator display section 22 , the customer display section 23 , the printing section 24 , the card reader/writer 25 , and the code reader 27 . In the following description, for convenience of explanation, it will be assumed that the control unit 100 performs the control performed by the controller 16.

The operation unit 21 includes a payment key 211, a total amount key 212, a fraction key 213, a yes key 214, and a no key 215. The payment key 211 is operated when starting payment in a transaction with a customer. The full amount key 212 is operated when charging the full amount of change to the card C. The fractional key 213 is operated when charging the card C with a predetermined fractional amount of the amount of change. A predetermined fractional amount is an amount less than the amount of change, such as a coin amount (999 yen or less), an amount less than 100 yen (99 yen or less), an amount less than 10 yen (9 yen or less), etc. say. If coins are not used as change, a classification for charging the amount of coins is set in advance on the card C as a classification for the amount to be charged. In this case, the amount of change less than 999 yen is charged to card C, and only banknotes of 1000 yen or more are paid as change. If coins less than 100 yen are not handled as change, a classification for charging amounts of 99 yen or less is set in advance on card C. In this case, the amount of change that is 99 yen or less is charged to card C, and the banknotes and coins that are 100 yen or more are paid as change. If coins less than 10 yen are not handled as change, a classification for charging amounts of 9 yen or less is set in advance on card C. In this case, the amount of change that is less than 9 yen is charged to the storage medium, and the banknotes and coins that are more than 10 yen are paid as change. The fractional amount is stored in advance in the card C held by the customer, and is read by the card reader/writer 25 from the card C touched or held over. That is, the classification information indicating the fractional amount to be charged is stored in advance in the card C for each customer.

Incidentally, it is also possible to store the fractional amount to be charged in the POS terminal 1 in advance and charge the fractional amount of the same unit to all customers. For example, the POS terminal may be set in advance to charge all customers with the amount equivalent to coins in their change.

Yes key 214 is operated when charging change to card C. The No key 215 is operated when not charging change to card C (that is, when receiving the entire change in cash).

From here on, the functional configuration of the POS terminal 1 will be explained. FIG. 3 is a functional block diagram showing the functional configuration of the POS terminal 1. As shown in FIG. The control unit 100 controls sales registration means 101, size determination means 102, change calculation means 103, display means 104, selection means 105, charging means by following the control program stored in the control program section 141 of the ROM 12 and the memory section 14. 106.

Sales registration means 101 performs sales registration processing for products to be sold.

The size determining means 102 determines whether the payment amount is greater than the purchase amount. Specifically, the size determining means 102 compares the input payment amount with the purchase amount, which is the total amount (tax included) of the products for which sales registration has been processed, and determines whether the payment amount is greater than the purchase amount. .

The change calculation means 103 calculates the amount of change related to the transaction from the purchase price of the product and the payment amount in cash. Specifically, the change calculation means 103 calculates the difference between the payment amount and the purchase amount when the size determination means 102 determines that the payment amount is greater than the purchase amount. That is, the change calculation means 103 subtracts the purchase amount from the payment amount to calculate the difference. The change calculation means 103 does not calculate the difference between the payment amount and the purchase amount when the size determination means 102 determines that the payment amount is not greater than the purchase amount.

The display means 104 selectably displays a plurality of types of amounts to be stored in the card C, which are less than the calculated change amount, on the operator display section 22. Specifically, the display unit 104 displays an image of the full amount key and an image of the fractional key on the operator display section 22. The amount of change (money) calculated by the change calculation means 103 is displayed on the image of the full amount key. A predetermined fractional amount of the change amount calculated by the change calculating means 103 is displayed on the image of the fractional key.

The selection means 105 determines which of the plurality of displayed change amounts has been selected. Specifically, the selection means 105 determines which key, the full amount key 212 or the fractional number key 213, has been operated. A full amount key 212 is provided on the image of the full amount key. Further, a fraction key 213 is displayed on the image of the fraction key. That is, when the operator touches the full amount key 212 on the image of the full amount key, the full amount key 212 is selected and operated. Further, when the operator touches the fraction key 213 on the image of the fraction key, the fraction key 213 is selected and operated.

To simplify the explanation, hereinafter, the full amount key 212 indicates that the image of the full amount key is displayed on the operator display section 22, and the fraction key 213 indicates that the image of the fractional key is displayed. Explain that it will be displayed. Further, it will be explained that the amount of change is displayed on the full amount key 212 and the fractional amount is displayed on the fraction key 213.

Furthermore, when a fractional amount is selected, the display means 104 displays the remaining amount of change after subtracting the fractional amount from the amount of change as cash change. Specifically, when the fractional key 213 is selected, the display means 104 displays the remaining amount of change obtained by subtracting the fractional amount displayed on the fractional key 213 from the amount of change.

The charging means 106 charges the card C with a monetary value related to the amount of change determined to be selected. Specifically, when the selection means 105 determines that the full amount key 212 has been operated, the charging means 106 stores in the card C a monetary value corresponding to the amount of change calculated by the change calculation means 103. Further, when the selection means 105 determines that the fraction key 213 has been operated, the charging means 106 stores in the card C a monetary value corresponding to a predetermined fraction of the change amount calculated by the change calculation means 103. do. In the embodiment, the charging means 106 stores on the card C a monetary value corresponding to the amount of change for coins out of the amount of change.

From here on, control of the POS terminal 1 will be explained. FIG. 4 is a flowchart showing the flow of control processing of the POS terminal 1. As shown in FIG. 4, the control unit 100 of the POS terminal 1 determines whether the code reader 27 has read a symbol such as a barcode attached to the product (S11). If it is determined that the code reader 27 has read the symbol (Yes in S11), the control unit 100 obtains a product code that specifies the product based on the read symbol (S12). Then, the sales registration means 101 performs sales registration processing for the product based on the obtained product code (S13). Then, the control unit 100 displays product information of the product for which the sales registration process has been performed on the operator display unit 22 (S14). The same information is also displayed on the customer display section 23. The control unit 100 then returns to S11.

FIG. 5 shows an example of a screen displayed on the operator display section 22 by the control section 100 in S23. In FIG. 5, the screen M1 displays product information M11 that displays product information of products for which sales registration has been performed, and purchase amount M12 that displays the total amount including tax (purchase amount) of the products for which sales registration has been performed. In the example of FIG. 5, the product information M11 displays product information (product name, price) related to product A, product B, and product C that have undergone sales registration processing. In addition, the purchase amount M12 displays the total amount including tax (purchase amount) of product A, product B, and product C.

Returning to the explanation of FIG. 4. If it is determined that the symbol has not been read (No in S11), the control unit 100 determines whether the payment key 211 has been operated (S21). If it is determined that the payment key 211 has been operated (Yes in S21), the control unit 100 executes the payment processing in S22 to S41. That is, the control unit 100 determines whether the payment amount has been input (S22). The payment amount can be entered, for example, by inputting the amount of cash handed over by the customer or a gift certificate with change from the operation unit 21, or by inserting the cash handed over by the customer into a change machine and then inputting the amount from the change machine. There are methods for inputting information according to the input amount, etc.

The size determining means 102 waits until the payment amount is input (No in S22), and if it is determined that the payment amount has been input (Yes in S22), the size determination means 102 selects the input payment amount and the product that has undergone sales registration processing. The payment amount is compared with the purchase amount stored in the information section 131, and it is determined whether the payment amount is greater than the purchase amount (S23). If it is determined that the payment amount is greater than the purchase amount (S23: Yes), the change calculation means 103 calculates the change amount for the transaction from the purchase amount of the product and the cash payment amount (S24). . That is, the change calculation means 103 subtracts the purchase amount from the payment amount to calculate the difference. Next, the control unit 100 displays a confirmation screen on the operator display unit 22 asking whether to charge change to the card C (S25).

FIG. 6 shows an example of a screen displayed on the operator display section 22 by the control section 100 in S25. In FIG. 6, the screen M2 includes a purchase amount M21 that displays the total amount including tax (purchase amount), a payment amount M22 that displays the payment amount, and a change amount M23 that displays the change amount calculated by the change calculation means 103 in S24. , a message M24 asking whether to charge change to the card is displayed. In the example of FIG. 6, the purchase amount M21 displays a total amount including tax of 6,800 yen. A payment amount of 10,000 yen is displayed in the payment amount M22. The change amount M23 displays a change amount of 3200 yen. The message M24 displays characters for confirming to the customer about charging the change, such as "Do you want to charge the change to electronic money?".

Further, an image of a yes key and an image of a no key are displayed on the screen M2. A yes key 214 is provided on the yes key image. A No key 215 is provided on the No key image. The operator confirms the customer's intention to charge the change, and when the customer indicates the intention to charge the change to the card C, the operator operates the yes key 214. Further, if the customer does not charge the change to the card C and indicates an intention to receive the entire amount in cash, the operator operates the No key 215.

In order to simplify the explanation, from now on, it will be explained that the image of the Yes key is displayed on the operator display section 22, that the image of the Yes key 214 is displayed, and that the image of the No key is displayed is expressed as the No key 215. will be displayed.

Returning to the explanation of FIG. 4. Next, the control unit 100 determines whether the yes key 214 has been operated (S26). If it is determined that the yes key 214 has been operated (Yes in S26), the display means 104 displays the full amount key 212 and the fraction key 213 on the operator display section 22 (S27).

FIG. 7 shows an example of a screen displayed on the operator display section 22 by the control section 100 in S27. In FIG. 7, the screen M3 displays a change amount M31 that displays the change amount calculated by the change calculation means 103 in S24, and a message M32 for selecting the amount to be charged. In the example of FIG. 7, 3200 yen is displayed as the change amount M31. The message M32 also displays characters prompting the customer to select the amount to be charged, such as "Please select the amount to be charged."

Further, a full amount key 212 and a fractional number key 213 are displayed on the screen M3. The amount to be charged is displayed on the displayed full amount key 212 and fractional amount key 213, respectively. In the example of FIG. 7, the full amount key 212 displays the full amount of change, 3200 yen. Further, on the full amount key 212, characters of a message (full amount) indicating that 3,200 yen is the full amount of change are displayed in association with the amount. The operator can see the display of the full amount key 212 and recognize the amount to be charged by operating the full amount key 212 and that the amount is the full amount of change.

Further, the fraction key 213 displays the amount of change to be charged, 200 yen. Further, on the fraction key 213, characters of a message (coin portion only) indicating that 200 yen is part of the change and the change of coins are displayed in association with the amount. The operator looks at the display on the fraction key 213 and determines the amount to be charged by operating the fraction key 213, and that the amount is part of the change, and in the example of FIG. 7 is the full amount of coins. can be recognized. Note that if the message (coins only) is changed to a message (99 yen or less), it can be recognized that the amount to be charged is 99 yen or less. Furthermore, if the message (coins only) is changed to a message (less than 9 yen), it can be recognized that the amount to be charged is less than 9 yen. Note that a screen with the same content as the screen displayed on the operator display section 22 in S27 may also be displayed on the customer display section 23. In this case, the customer can also confirm and understand the same information (change amount and fractional amount) in the same way as the operator.

Returning to the explanation of FIG. 4. Next, the selection means 105 determines which key, the full amount key 212 or the fractional number key 213, has been operated. First, the selection means 105 determines whether the full amount key 212 has been operated (S28). If it is determined that the full amount key 212 has been operated (Yes in S28), the control unit 100 causes the card reader/writer 25 to be stored in the card C by touching or holding the card C over the card reader/writer 25. It is determined whether information (including information on monetary value) has been received (S29). The charging means 106 waits until the information stored in the card C is received (No in S29), and when it is determined that the information stored in the card C has been received (Yes in S29), the charging means 106 calculates the change. The monetary value corresponding to the total amount of change calculated by the means 103 is stored in the card C (S30). Then, the control unit 100 displays the amount charged in S30, etc. on the operator display unit 22 (S31).

FIG. 8 shows an example of the screen displayed by the control unit 100 in S31. In FIG. 8, the screen M4 includes a charging amount M41 displaying the full amount of change that the charging means 106 charged to the card C in S30, a message M42 indicating that the card C has been charged, and a message M42 indicating that the charging means 106 has charged the card C. Displays the amount M43 of monetary value. In the example of FIG. 8, the charge amount M41 is displayed as 3200 yen as the total amount of change charged. The message M42 displays, for example, the words "Electronic money has been charged to the specified amount." The amount M43 is the sum of the amount read from the card C in S29 and the amount charged in S30.

Returning to the explanation of FIG. 4. Next, the control unit 100 uses the printing unit 24 to print product information (product name, price, etc. of the product whose sales have been registered) and payment information (total amount, payment amount, change amount, charge amount, etc.) related to the transaction. A receipt is issued (S41). After viewing the receipt, the customer can confirm the amount of change that has been charged. The control unit 100 then returns to S11.

On the other hand, if it is determined in S28 that the full amount key 212 has not been operated (No in S28), it is determined whether the fraction key 213 has been operated (S32). If it is determined that the fraction key 213 has been operated (Yes in S32), the control unit 100 causes the card C to be brought into contact with or held over the card reader/writer 25, so that the card reader/writer 25 is stored in the card C. (S33). The charging means 106 waits until the information stored in the card C is received (No in S33), and if it is determined that the information stored in the card C has been received (Yes in S33), the charging means 106 waits until the information stored in the card C is received (No in S33). A monetary value corresponding to a portion of the amount of change calculated by the change calculating means 103 according to the classification information is stored in the card C (S34). In the embodiment, since the customer's card C is set in advance to be charged with coins, the card C stores a monetary value equivalent to the amount of change for coins. Then, the control unit 100 displays on the operator display unit 22 the amount charged in S34, the amount of change to be received in cash, etc., which is obtained by subtracting the charged amount from the amount of change (S35).

FIG. 9 shows an example of the screen displayed by the control unit 100 in S35. In FIG. 9, the screen M5 displays an amount M51 charged to the card C, a message M52 indicating that the card C has been charged, and an amount M53 of the monetary value stored in the card C due to the charging. In the example of FIG. 9, the amount M51 is displayed as 200 yen, which is the amount equivalent to the coins of the charged change. The message M52 displays, for example, the words "Electronic money has been charged to the specified amount." The amount M53 is the sum of the amount read from the card C in S33 and the amount charged in S34. Further, the screen M5 displays an amount M54 of the change to be paid in cash. In the embodiment, the coin portion of the change is charged, so in the example of FIG. 9, the change amount (3000 yen) of the change paid in banknotes, which is obtained by subtracting the charged amount from the change amount, is displayed in the amount M54.

Next, the control unit 100 performs a payout process for paying change (S36). For example, when making a change machine pay change, information for the amount to be paid (in the embodiment, information for dispensing 3000 yen) is transmitted to the change machine. Furthermore, when paying bills stored in the money storage box 5 as change, the control unit 100 outputs a signal to open the money storage box 5. Then, the money storage box 5 is opened, and it becomes possible to pay bills as change to the customer. The control unit 100 then executes the process of S41.

Note that if it is determined in S26 that the Yes key 214 was not operated (that is, the No key 215 was operated) (No in S26), the control unit 100 executes the process of S41. Further, in S32, if it is determined that the operation is not the fraction key 213 (No in S32), the control unit 100 returns to S28.

Further, if it is determined in S23 that the payment amount is not greater than the purchase amount (that is, the payment amount and the purchase amount are the same amount) (No in S23), the control unit 100 executes the process in S41. Although not shown, in S23, if the payment amount is less than the purchase amount, since the payment amount is insufficient, error processing such as displaying a message prompting the user to replenish the payment amount is performed. Further, in S21, if it is determined that the payment key 211 is not operated (No in S21), the control unit 100 returns to S11.

The POS terminal 1 of this embodiment includes a change calculating means 103 that calculates change from the purchase amount of the product and the amount paid in cash, and a plurality of change calculation means 103 that calculates the change amount from the purchase amount of the product and the payment amount in cash, and a plurality of amounts that are within the calculated change amount and are stored in the card C. A display means 104 for displaying change amounts of different types in a selectable manner; a selection means 105 for determining which of the plurality of displayed change amounts has been selected; charging means 106 for charging C. Such a POS terminal 1 can charge multiple types of change amounts to the card C. Therefore, you can receive the amount of change depending on the situation at that time. For example, if you don't need small change but want a lot of cash, you can charge the coins that are part of the change and receive the remaining amount in cash.
