Description

An embodiment of the present invention relates to a sales data processing device and program.

Conventionally, a point system has been widely used in which points are given to customers according to the purchase amount, and the customers can use the acquired points in subsequent transactions for discounts and the like. In such a point system, for example, a server of a point management company (hereinafter referred to as a point management server) collectively manages accumulated points of customers according to a member number or a card number of a point card. There is an operating method. In such an operation method, a sales data processing device such as a POS (Point Of Sales) terminal in a store exchanges data with a point management server to perform processing related to points. Examples of point transactions include the use of points (also referred to as point redemption), the addition of points according to the purchase price, and the addition of points (refund) at the time of return.

By the way, there is a possibility that the processing at the POS terminal may be interrupted due to a power failure, freezing of the device, or the like during the point transaction processing. In such a case, the transaction being processed at the POS terminal will be forcibly terminated without being completed, and the transaction data will not be saved. On the other hand, when the point transaction is started and the point management server has already received the point transaction data instructing the point addition/subtraction, the point management server side may execute the point addition/subtraction processing. . In addition, since some point transaction data is recorded on the point management server side, discrepancies may occur between the record of the point transaction at the store and the record of the point transaction at the point management server.

In addition, when a transaction such as the use or addition of points is redone at the store along with the product transaction, there arises a problem that the point transaction is registered twice in the point management server. When such a problem occurs, it is necessary for the clerk to contact the point management server, and the point management server can receive this communication to eliminate double registration and eliminate discrepancies in transaction records. . However, in general, there is a background that customer service and cash registering must be prioritized at stores, and contacting the point management server is often postponed. A function that can be used was desired.

The problem to be solved by the present invention is to provide a sales data processing device and program that can prevent double registration of point transactions.

A sales data processing device of an embodiment includes transaction management means and notification means. The transaction management means changes the flag value of the point transaction flag indicating that the point transaction is being processed to the first value when the point transaction processing is started, and changes the flag value to the first value when the point transaction processing is completed. to a second value. The notification means performs notification based on the flag value of the point transaction flag at the switching timing of the screen displayed by the own device. Further, the notification means performs notification when the flag value of the point transaction flag is the first value.

Also, the program executed by the POS terminal 1 of this embodiment may be provided or distributed via a network such as the Internet.

The program executed by the POS terminal 1 of the present embodiment has a module configuration including an input reception section 51, a transaction management section 52, a display control section 53, and a print control section 54, as shown in FIG. As actual hardware, the CPU loads the programs of the present embodiment from the storage medium (ROM) and executes them, thereby loading the above units onto the main storage device. Then, the CPU generates an input reception section 51, a transaction management section 52, a display control section 53, and a print control section 54 on the main storage device.

The input reception unit 51 receives input to the touch panel provided in the keyboard 15, the scanner 16, the magnetic card RW 17, the non-contact RW 18, the store clerk display 19, and the customer display 21, and information received via the communication I/F 13. Accepts input such as

Further, the input reception unit 51 receives input of identification information of the point member. For example, the input reception unit 51 receives input of the point card number read from the point card by the magnetic card RW17. The input reception unit 51 may also receive an input of a point card number via the keyboard 15 or a touch panel on the store clerk display 19 . The input reception unit 51 may also receive an input of a point card number via the contactless RW 18 .

The input receiving unit 51 also receives the product code read by the scanner 16 or the product code input from the keyboard 15 .

Further, the input reception unit 51 receives key operations such as the cash total key 150 and the confirmation key 151 through operations on the touch panel on the store clerk display 19 or the keyboard 15 . The input reception unit 51 receives instructions regarding point transactions, that is, the above-described point classifications and the number of points in the classification (for example, the number of points to be used) via an operation on the touch panel on the clerk display 19 or the keyboard 15. Accept input.

The transaction management unit 52 manages registration processing for sales, returned goods, etc., and processing for points. For example, the transaction management unit 52 reads the product information corresponding to the product code received by the input reception unit 51 from the product master 201 , temporarily registers it as product information of the product to be sold, and outputs it to the display control unit 53 .

Further, when the input reception unit 51 receives the point card number, the transaction management unit 52 inquires of the point management server 6 about the point balance corresponding to the point card number, and reads it from the point master 681 . Further, when the cash total key 150 is operated, the transaction management unit 52 calculates the total amount of the transaction based on the temporarily registered product information, and calculates the number of points to be added according to the total amount.

When the input accepting unit 51 accepts an instruction to pay using points, the transaction managing unit 52 subtracts the number of points used from the total amount to calculate the billed amount after using the points. In addition, the transaction management unit 52 calculates the total amount of returned goods when registering the return of goods, and calculates the number of points to be refunded according to the refunded amount.

When the confirmation key 151 is operated, the transaction management unit 52 confirms the temporarily registered product information, the total amount of money, the data of the point transaction, the amount information of the payment, and the like, and performs the process of closing one transaction. That is, the transaction management unit 52 records the transaction data for one transaction in the transaction data 202, and also outputs the data to the store server 4 for storage. When the customer presents the point card, the stored transaction data includes the above-described point transaction data.

Further, when the confirmation key 151 is operated, the transaction management unit 52 transmits point transaction data indicating the number of points to be added or the number of points to be subtracted for the transaction to the point management server 6, and Complete the point transaction process.

Also, the transaction management unit 52 manages the flag value of the point transaction flag 203 . That is, when the point transaction processing is started, the transaction management unit 52 changes the flag value of the point transaction flag 203 to 1 (first value). Further, the transaction management unit 52 changes the flag value of the point transaction flag 203 to 0 (second value) after completing the processing of the point transaction.

An example of the timing of changing the flag value to 1 is the timing when the input receiving unit 51 receives the input of the point card number from the point card. Further, as an example of the timing of changing the flag value to 0, the timing at which the enter key 151 is selected and operated may be used.

The display control unit 53 controls display processing in the store clerk display 19 or the customer display 21 . For example, the display control unit 53 displays a registration screen 60 (see FIG. 6) for registering a product for sale on the sales clerk display 19 . The display control unit 53 displays the product information read from the product master 201 by the transaction management unit 52 on the registration screen 60 .

Further, if the flag value of the point transaction flag 203 is 1, the display control unit 53 displays on the salesclerk display 19 a message notifying that an incomplete point transaction has occurred. The timing for referring to the point transaction flag 203 may be when the POS terminal 1 is started up (for example, after restarting after forced termination). As a result, when the POS terminal 1 is restarted, it can be confirmed at an early stage that the clerk needs to contact the point management company.

Another timing can be a standby timing at which a new transaction can be started, that is, a timing after one transaction is confirmed. As a result, the clerk can confirm the necessity of contacting the point management company when the registration work is completed.

In addition, the display control unit 53 refers to the flag value of the point transaction flag 203 at the timing of switching between the returned goods registration screen, the sales data display screen, and other various screens, and displays an alert display 70 (see FIG. 6). may be output.

Hereinafter, with reference to FIG. 6, an example will be described in which an alert screen is displayed as a pop-up at the standby timing when the previous transaction is finished and the next new transaction can be started.

FIG. 6 is a diagram showing an example of an alert display 70 displayed by the POS terminal 1. As shown in FIG. For example, the display control unit 53 pops up an alert display 70 on the registration screen 60 . Note that the display method of the alert display 70 is not limited to pop-up display, and may be displayed by incorporating it into the registration screen 60, for example. As shown in FIG. 6, the alert display 70 includes a message notifying the store clerk that the point transaction has been interrupted in the own device. Also, the alert display 70 includes a message prompting the store clerk to contact a call center such as a point management company.

The alert display 70 can be terminated by operating the clear key of the keyboard 15, for example. As a result, the clerk can immediately end the alert display 70 and start the registration work when the customer is lined up at the register. However, this operation hides the alert display 70 on the spot. As long as the flag value of the point transaction flag 203 is 1, the display control unit 53 displays the alert display 70 again at the start of the next transaction (that is, at the time when the registration process of the previous transaction is completed with the confirmation key 151). pop up. By repeatedly outputting the alert display 70 while the flag value is 1, it is possible to prevent the point management company from being left uncontacted.

The print control unit 54 outputs print data to the printer 22 and controls printing and issuing of receipts and journals. That is, the print control unit 54 generates receipt print data and journal print data using the product transaction data and point transaction data for one transaction, and outputs them to the printer 22 . The printer 22 prints receipts and journals based on the input print data.

Next, a procedure example of alert display processing executed by the POS terminal 1 will be described. In addition, below, the example of the procedure which outputs an alert display at the time of a registration process is demonstrated.

FIG. 7 is a flow chart showing a procedure example of registration processing executed by the POS terminal 1. As shown in FIG. First, when the POS terminal 1 is activated, the display control unit 53 reads the flag value of the point transaction flag 203 and determines whether or not the flag value is 1 (step S1). If the flag value is 1 (step S1: Yes), the display control unit 53 outputs an alert display 70 to the store clerk display 19 (step S2). When the operation of the clear key is received on the keyboard 15 or the store clerk display 19 (step S3: Yes), the display control unit 53 terminates the alert display 70 and proceeds to step S4. While the operation of the clear key is not accepted (step S3: No), the display control unit 53 continues to display the alert display 70. FIG.

If step S1: No or step S3: Yes, the transaction management unit 52 performs product registration processing (step S4). That is, when the input reception unit 51 receives the input of the product code, the transaction management unit 52 reads the product information corresponding to the product code from the product master 201 and temporarily registers it. Also, when the input receiving unit 51 receives the operation of the cash total key 150, the transaction management unit 52 calculates the total amount of the transaction.

When the magnetic card RW 17 reads the point card number from the magnetic information of the point card, the input receiving unit 51 receives the point card number (step S5: Yes). Note that the process of step S5 may be interruptible during the product registration process of step S4.

Next, the transaction management unit 52 changes the flag value of the point transaction flag 203 from the initial value of 0 to 1 (step S6). The transaction management unit 52 also transmits the point card number read in step S5 to the point management server 6, and inquires about the point information associated with the point card number (step S7). Upon receiving point information such as the point balance and membership rank from the point management server 6, the display control unit 53 displays the information such as the point balance on the registration screen 60 (step S8). The store clerk asks the customer whether or not to use the points.If the points are to be used (step S9: Yes), the clerk operates the point use key, inputs the number of points to be used from the keyboard 15, and presses the confirmation key 151. Operate (step S10: Yes).

When the confirmation key 151 is operated (step S10: Yes), the transaction management unit 52 transmits the point card number and the number of used points to the point management server 6. FIG. When the number of used points exceeds the current balance of points and is incorrectly input, the point management server 6 transmits a response of unusable to the POS terminal 1. - 特許庁On the other hand, if the number of used points is within the current point balance, the point management server 6 transmits and responds to the POS terminal 1 with a planned point balance obtained by subtracting the number of used points from the current point balance. Input is waited until the number of points to be used is input and the confirmation key 151 is operated (step S10: No).

The transaction management unit 52 subtracts the number of used points accepted in step S10 from the total amount calculated in step S4 to update the billed amount (step S11). The transaction management unit 52 performs payment processing for the remaining amount after subtracting the number of points used (step S12). That is, the transaction management unit 52 inputs the amount deposited by the customer and performs processing according to the payment method, such as cash payment, electronic money payment, or credit card payment.

When the confirmation key 151 is operated (step S13: Yes), the transaction management unit 52 collects the product information provisionally registered in step S4, the number of points to be used input in step S10, the amount related to the payment processing in step S12, and the amount related to accounting. Information and the like are recorded in the transaction data 202 and transmitted to the store server 4 . The transaction management unit 52 also transmits the point transaction data to the point management server 6 and records it in the point transaction data 682 (step S14). Step S13: If No, wait for the operation of the enter key 151 (step S13).

If points are added according to the payment balance even when points are used, the transaction management unit 52 may calculate the number of points and include it in the transaction data and point transaction data in step S14. After that, the transaction management unit 52 returns the flag value of the point transaction flag 203 from 1 to 0 (step S15), and proceeds to the next transaction (step S1).

If points are not used (step S9: No), the transaction management unit 52 performs payment processing for the total amount calculated in step S4 (step S16). When the confirmation key 151 is operated (step S17: Yes), the transaction management unit 52 stores the product information provisionally registered in step S4, the number of points to be added calculated from the total amount, and information on the payment process in step S16 as transaction data. 202 and transmitted to the store server 4 . Further, the transaction management unit 52 transmits point transaction data including the number of added points to the point management server 6, and records it in the point transaction data 682 (step S18). Thereafter, the transaction management unit 52 returns the flag value of the point transaction flag 203 from 1 to 0 (step S19), and proceeds to the next transaction (step S1). Step S17: If No, wait for the operation of the enter key 151 (step S17).

If the point card is not read (step S5: No), there is no point transaction, so the transaction management unit 52 performs payment processing for the total amount, inputs the amount deposited by the customer, and calculates the change amount. Processing is performed (step S20). When the confirmation key 151 is operated (step S21: Yes), the transaction management unit 52 stores the product information provisionally registered in step S4, the amount related to the payment processing in step S20, information related to accounting, etc., in the transaction data 202 of the HDD 20. It is recorded and transmitted to the shop server 4 (step S22). The print control unit 54 generates print data based on the transaction data, prints receipts and journals, and completes the processing of one transaction. After that, the process moves to step S1. Step S21: If No, the operation of the enter key 151 is waited.

Next, an example of the recording status of transaction data and the status of the point transaction flag 203 when the POS terminal 1 is forcibly terminated during registration processing involving point transactions will be described with reference to FIGS. 8 and 9. FIG.

FIG. 8 is a diagram showing an example of point transaction data 682 saved in the point management server 6 before forced termination of the POS terminal 1. As shown in FIG. FIG. 9 is a diagram showing an example of transaction data 202 when part of the data is not saved due to forced termination of the POS terminal 1. As shown in FIG.

For example, with respect to the point card number 01239999, in step S10 of FIG. 7, it was entered that 1000 points would be used. Assume that the POS terminal 1 could not save the data related to the transaction.

Then, for example, in the point transaction data 682 of the point management server 6, as shown in FIG. is recorded as point transaction information indicating that the On the other hand, since the POS terminal 1 has not been able to save the transaction data for this transaction, the transaction data 202 of the POS terminal 1 contains the point transaction data corresponding to the above transaction with the point card number 01239999, as shown in FIG. Not recorded.

However, according to the POS terminal 1 of this embodiment, the point transaction flag 203 is changed to 1 in step S6 before transmitting the number of used points to the point management server 6 in step S10 of FIG. Therefore, even if the POS terminal 1 is forcibly terminated before the transaction is confirmed in step S13, the point transaction flag 203 maintains the flag value of 1. As a result, when the POS terminal 1 is restarted or when the next transaction is started, the point transaction flag 203 is read in step S1 and an alert is displayed in step S2. In this way, the POS terminal 1 can notify the clerk of the interrupted point transaction.

While several embodiments of the invention have been described, these embodiments have been presented by way of example and are not intended to limit the scope of the invention. These novel embodiments can be implemented in various other forms, and various omissions, replacements, and modifications can be made without departing from the scope of the invention. These embodiments and modifications thereof are included in the scope and gist of the invention, and are included in the scope of the invention described in the claims and equivalents thereof.

For example, in the above description, it is reported that the point transaction has been interrupted by outputting the alert display 70, but the reporting method is not limited to this. The notification may be made by voice output or alert sound, or the content of the alert may be notified to another information processing device such as the shop server 4 or the like.

Further, in the above description, when starting product registration for a new transaction, the flag value of the point transaction flag 203 is read, and if the flag value is 1, the alert display 70 is displayed on the registration screen 60. The timing of reading the value is not limited to this. As another timing, the POS terminal 1 may read the flag value of the point transaction flag 203 when the device is started, and display the alert display 70 if the flag value is 1.

Also, the print control unit 54 may generate journal print data including the flag value of the point transaction flag 203 in each transaction. This will print out the flag value for each transaction in the journal. When the alert display 70 appears, the store clerk can use the journal to confirm when the transaction interruption occurred.

As described above, the POS terminal 1 of this embodiment changes the point transaction flag to the first value (for example, 1) when the point transaction process is started, and changes the flag value to the second value when the point transaction process is completed. value (eg, 0). Then, if the point transaction flag is the first value, the POS terminal 1 notifies that an incomplete point transaction has occurred. As a result, the store clerk can determine that an incomplete point transaction has occurred at the POS terminal 1, so that the point management company or the like can be contacted to confirm any discrepancies in the transaction data. Therefore, according to this embodiment, it is possible to provide a sales data processing device and program that can prevent double registration of point transactions.
