Description

The embodiments of the present invention relate to a payment processing apparatus, its control program , and a payment processing method .

POS systems with prehandling systems are known.

For example, the flow of settlement processing using the pre-handling system is as follows.

(1) A salesclerk in charge of pre-handling causes a handy terminal to read the PLU (price look up) code of each product purchased by a customer waiting for payment.

(2) A pre-registration ticket containing a two-dimensional bar code representing all of the PLU codes read by the handy terminal is printed, and the pre-handling clerk hands the pre-registration ticket to the customer.

(3) When the customer whose turn to pay the bill hands the pre-registration ticket to the cashier, the cashier makes the POS terminal read the two-dimensional barcode printed on the pre-registration ticket.

(4) The POS terminal registers all commodities corresponding to all PLU codes indicated by the two-dimensional bar code as objects of payment.

Japanese Unexamined Patent Application Publication No. 2011-53842

If the same pre-registered ticket is read multiple times by the POS terminal, the same purchased product will be registered redundantly.

Under these circumstances, it has been desired to prevent unnecessary registration of purchased products while taking advantage of the advantages of the pre-handling system.

The payment processing apparatus of the embodiment includes retrieval means, calculation means, display means, and payment means. The retrieving means retrieves, from the two-dimensional code, two-dimensional code identification information including transaction identification information for identifying each transaction of purchased products input from a plurality of terminals. When the transaction identification information included in the two-dimensional code identification information extracted by the extraction means is not stored in the storage unit, the calculation means calculates the purchase price associated with the transaction identified by the two-dimensional code identification information extracted by the extraction means. The product information of the product is acquired, and based on the product information, the total amount of the purchased product related to the transaction identified by the two-dimensional code identification information extracted by the extraction means is calculated. The display means causes the display unit to display the total amount calculated by the calculation means. The payment means performs payment processing for the purchased product based on the total amount calculated by the calculation means. When the transaction identification information taken out by the taking-out means is stored in the storage part, the calculating means does not calculate the total amount of purchased commodities related to the transaction identified by the two-dimensional code identification information taken out by the taking-out means.

Next, the operation of the POS system 100 configured as above will be described.

FIG. 5 is a flow chart of the CPU 1a.

When the pre-handling clerk intends to issue a pre-registration ticket to a customer waiting in line at the register corner of the store, the input device 1e is operated to instruct the start of processing for that purpose. When a command related to this operation is output from the input device 1e, the CPU 1a starts the processing shown in FIG.

At step Sa1, the CPU 1a clears the commodity table in the RAM 1c.

In steps Sa2 to Sa4, the CPU 1a waits for any one of bar code scanning, quantity designation, and issuing instruction.

The salesclerk in charge of prehandling holds the bar code printed on the product purchased by the customer over the bar code scanner 1d. Then, the barcode scanner 1d reads the barcode and outputs the PLU code represented by the barcode. Therefore, if the barcode scanning is performed in this manner, the CPU 1a proceeds from step Sa2 to step Sa5.

At step Sa5, the CPU 1a updates the product table to include the PLU code output by the barcode scanner 1d. Specifically, for example, if the PLU code output by the barcode scanner 1d is not included in the product table, the PLU code is added to the product table, and the quantity information is set to "1" in association with the PLU code. ” is added. If the PLU code output by the barcode scanner 1d is already included in the product table, the quantity information associated with that PLU code is incremented by one. After that, the CPU 1a returns to the standby state of steps Sa2 to Sa4.

On the other hand, if the salesclerk in charge of prehandling wants to change the quantity of the product for which the bar code was scanned just before, he/she operates the input device 1e to specify the quantity. The CPU 1a advances from step Sa3 to step Sa6 in response to the operation of designating such a quantity.

At step Sa6, the CPU 1a increases the quantity associated with the PLU code most recently obtained by bar code scanning by one less than the specified quantity. After that, the CPU 1a returns to the standby state of steps Sa2 to Sa4.

The sales clerk in charge of pre-handling repeats bar code scanning and quantity designation as appropriate, and sequentially registers the products that the customer purchases. After completing registration of all registrable commodities, the salesclerk in charge of pre-handling operates the input device 1e to issue a pre-registration ticket. When a command related to this operation is output from the input device 1e, the CPU 1a proceeds from step Sa4 to step Sa7.

At step Sa7, the CPU 1a determines the transaction serial number. The transaction serial number is, for example, a four-digit numerical value, and the CPU 1a determines a larger transaction serial number each time step Sa7 is executed. As a result, the transaction serial number becomes identification information that does not substantially overlap.

At step Sa8, the CPU 1a creates image information representing the pre-registration ticket.

FIG. 6 is a diagram showing an example of a pre-registration ticket.

The CPU 1a includes the two-dimensional code 61 in the pre-registration ticket. The two-dimensional code 61 is created by representing each of the terminal code of the handy terminal 1, the transaction serial number determined in step Sa7, the PLU code included in the product table, and the quantity information associated with the PLU code. do. Thus, the two-dimensional code is an example of pre-registration information. If there are a plurality of handy terminals 1, the same transaction serial number may be determined at the same time for these plurality of handy terminals 1. However, by combining the terminal code and the transaction serial number, it can be used as identification information for identifying the pre-registered ticket. The identification information that identifies the pre-registration ticket is also the identification information that identifies the two-dimensional code.

At step Sa9, the CPU 1a transmits the above image information to the portable printer 2 from the wireless communication section 1g.

When the image information transmitted from the handy terminal 1 as described above is transmitted to the portable printer 2, the wireless communication section 2g receives it. Then, the CPU 2a controls the printing device 2d to print the image represented by the image information. Under this control, the printing device 2d prints an image on paper, and a pre-registration ticket as shown in FIG. 6 is issued.

Thus, the CPU 1a has a function as recording control means.

The sales clerk in charge of pre-handling hands over the pre-registration ticket issued by the portable printer 2 to the customer.

FIG. 7 is a flow chart of the CPU 3a. By executing the processing shown in FIG. 7, the CPU 3a functions as processing means.

When the POS terminal 3 is activated or after the processing shown in FIG. 7 is finished, the CPU 3a starts the processing shown in FIG.

In step Sb1, the CPU 3a clears the product list area and turns off the batch flag. The batch flag can be implemented as 1-bit data stored in the RAM 3c , for example.

In steps Sb2 and Sb3, the CPU 3a waits for PLU input or scanning of the two-dimensional code.

Now, the cash register clerk can input the PLU code by holding the bar code printed over the product purchased by the customer, or by pressing the PLU key on the input device 3i. When the PLU code is input in this manner, the CPU 3a proceeds from step Sb2 to step Sb4.

At step Sb4, the CPU 3a acquires information associated with the input PLU code from the PLU file. Specifically, the CPU 3a acquires, for example, the department, item name and price from the PLU file. Then, the CPU 3a updates the product list area of the RAM 3c so as to include each information of PLU code, department, product name and price. Specifically, for example, if the acquired PLU code is not included in the product list area, the PLU code, department, product name, and price information are added to the product list area and associated with the PLU code. The quantity obtained is set to “1”. If the obtained PLU code was already included in the product listing area, then the quantity associated with that PLU code is incremented by one. After that, the CPU 3a proceeds to the waiting state of steps Sa5 to Sa8.

In the waiting state of steps Sa5 to Sa8, the CPU 3a waits for a new input of PLU, designation of quantity, scanning of a two-dimensional code, or payment instruction.

If PLU is input in the same manner as above, the CPU 3a performs the process of step Sab4 again, and then returns to the standby state of steps Sb5 to Sb8.

If the cash register clerk wants to change the quantity of the product for which the PLU code has been input just before, he/she operates the input device 3i to specify the quantity. The CPU 3a advances from step Sb6 to step Sb9 in response to the operation of designating such quantity.

In step Sb9, the CPU 3a increases the quantity associated with the most recently obtained PLU by one less than the specified quantity. After that, the CPU 3a returns to the waiting state of steps Sb5 to Sb8.

Now, the customer who has been handed the pre-registration ticket by the pre-handling clerk hands the pre-registration ticket to the cash register clerk. After receiving the pre-registration ticket, the cash register clerk holds the two-dimensional code of the pre-registration ticket over the two-dimensional code scanner 3h. Then, the two-dimensional code scanner 3h reads the two-dimensional code and outputs various data represented by the two-dimensional code (hereinafter referred to as read data). Thus, the two-dimensional code scanner 3h functions as reading means. The read data is stored in the RAM 3c by the two-dimensional code scanner 3h or by the CPU 3a. If the two-dimensional code is thus scanned, the CPU 3a proceeds from step Sb3 or step Sb7 to step Sb10.

In step Sb10, the CPU 3a executes batch addition processing.

FIG. 8 is a flowchart of the CPU 3a in batch addition processing and a flowchart of CPU 4a in processing associated with the batch addition processing.

At step Sc1, the CPU 3a extracts the terminal code and transaction serial number from the read data stored in the RAM 3c, creates confirmation request information including the terminal code and transaction serial number, and transmits it to the server 4 through the communication interface 3m.

Once the confirmation request information has been transmitted to the server 4 via the communication network 6, this confirmation request information is received by the communication interface 4e. The confirmation request information is stored in the RAM 4c by the communication interface 4e or by the CPU 4a. Then, in response to this, the CPU 4a starts the processing shown on the right side of FIG.

At step Sd1, the CPU 4a extracts the terminal code and the transaction serial number from the confirmation request information stored in the RAM 3c, and confirms whether or not the transaction information file contains a data record containing both the terminal code and the transaction serial number in the index. By doing so, it is confirmed whether or not the pre-registration ticket used this time is unused. Thus, the CPU 4a functions as determination means.

If the transaction information file does not contain a data record that includes both the relevant terminal code and transaction serial number in the index, the CPU 4a determines that the transaction information file is unused, and proceeds from step Sd1 to step Sd2.

At step Sd2, the CPU 4a transmits response information including the usable information to the POS terminal 3 from the communication interface 4e.

If the transaction information file contains a data record that includes both the corresponding terminal code and transaction serial number in the index, the CPU 4a determines that the file has been used, and proceeds from step Sd1 to step Sd3.

At step Sd3, the CPU 4a transmits response information including the unusable information to the POS terminal 3 from the communication interface 4e.

Once the response information has been transmitted to the POS terminal 3 via the communication network 6, this response information is received by the communication interface 3m. The response information is stored in the RAM 3c by the communication interface 3m or by the CPU 3a.

In step Sc2, the CPU 3a confirms whether or not the pre-registration ticket used this time is unused by confirming which of the usable information and the unusable information is included in the response information.

When the response information includes the usable information, the CPU 3a determines that it is unused, and proceeds from step Sc2 to step Sc3.

In step Sc3, the CPU 3a acquires information associated with each PLU code included in the read data from the PLU file. Then, the CPU 3a updates the product list area of the RAM 3c so as to include all of the acquired PLU code, department, product name and price information. Specifically, for example, if the PLU code is not included in the product list area, the PLU code, department, product name, and price information are added to the product list area, and the quantity associated with the PLU code is added to the product list area. is the numerical value indicated by the quantity information included in the read data in association with the PLU code. If the obtained PLU code is already included in the product list area, the quantity associated with the PLU code is increased by the value indicated by the quantity information included in the read data in association with the PLU code. Thus, the CPU 3a functions as processing control means.

In step Sc4, the CPU 3a turns on the collective flag. After that, the CPU 3a terminates the collective addition process.

On the other hand, when the response information includes the unusable information, the CPU 3a determines that it has been used, and proceeds from step Sc2 to step Sc5.

In step Sc5, the CPU 3a performs error processing. This error handling is done at least by confirming that the pre-registration ticket that was attempted to be used this time cannot be used because it has been used, that is, that the registration processing based on the information recorded on the pre-registration ticket has already been performed. Includes notification processing for notifying customers. This notification process is, for example, a process of displaying an image representing a message for the notification on at least one of the operation display 3j and the customer display 3k. Thus, at least one of the operation display 3j and the customer-side display 3k functions as notification means. The CPU 3a also functions as notification control means. The notification process may be a process of emitting an alarm sound from a ringing device (not shown) or outputting a voice message for the notification from an audio output device (not shown). Alternatively, the notification process may be a process of causing a light emitting device (not shown) to emit light. The error processing may include other processing such as updating error history information in addition to the notification processing. To update the error history information, for example, add a data record containing the terminal code and transaction serial number included in the current read data, the identification information of the POS terminal 3, the identification information of the cash register clerk, date and time information, and the like. .
As a result, based on the error history information, it is possible to analyze the situation in which the used pre-registration ticket is repeatedly scanned after the fact.

After completing the error processing, the CPU 3a terminates the collective addition processing.

After completing the collective addition process, the CPU 3a returns to the standby state of steps Sb5 to Sb8 shown in FIG.

As described above, when the two-dimensional code included in an unused pre-registration ticket is read by the two-dimensional code scanner 3h, the CPU 3a will eventually read all the products registered when the pre-registration ticket is issued. are collectively registered as purchased products. This eliminates the need for the cash register clerk to perform individual PLU entries for items whose barcodes have already been scanned by the pre-handling clerk.

After completing the registration of all the products purchased by one customer, the cash register clerk issues a settlement instruction by a predetermined operation such as pressing a subtotal key, which is one of function keys provided on the input device 3i. . If such a settlement instruction is issued, the CPU 3a proceeds from step Sb8 to step Sb11.

In step Sb11, the CPU 3a executes settlement processing.

FIG. 9 is a flow chart of the CPU 3a in the settlement process and a flow chart of the CPU 4a in the process associated with the settlement process.

At step Se1, the CPU 3a calculates the total price of the products registered in the product list area, and controls the operation display 3j and the customer display 3k to display the total price.

At step Se2, the CPU 3a waits for the completion of the receipt of money.

The cash register clerk receives money corresponding to the displayed total amount. This money collection may be performed by credit card payment or electronic money payment. When credit card settlement or electronic money settlement is performed, the CPU 3a may perform the processing therefor. After the payment is completed, the cash register clerk performs a predetermined operation such as pressing a predetermined key on the input device. In response to this operation, the CPU 3a determines that the receipt of money has been completed, and proceeds from step Se2 to step Se3.

At step Se3, the CPU 3a controls the receipt printer 3f to issue a receipt showing the list of products registered in the product list area and the total amount calculated at step Se1.

At step Se4, the CPU 3a confirms whether or not the collective flag is turned on. If the batch flag is ON, the CPU 3a proceeds from step Se4 to step Se5, and if it is OFF, proceeds from step Se4 to step Se6.

In step Se5 or step Se6, the CPU 3a prepares a transaction for notifying the server 4 of information regarding the current transaction. The CPU 3a includes the transaction serial number, transaction product information and total amount in the transaction. The transaction serial number is assigned by the CPU 3a or CPU 4a so that the current transaction can be identified. The traded product information includes the PLU code of the product purchased by the customer. The total amount is calculated in step Se1. The CPU 3a may include other information such as the identification information of the POS terminal 3, the identification information of the cash register clerk, or date and time information in the transaction. Further, the CPU 3a includes the terminal code and transaction serial number included in the read data in the transaction at step Se5, but does not include the terminal code and transaction serial number in the transaction at step Se6 because the read data is not obtained. The CPU 3a proceeds from step Se5 or step Se6 to step Se7.

At step Se7, the CPU 3a transmits the transaction created at step Se5 or step Se6 to the server 4 from the communication interface 3m.

Once the transaction has been transmitted to the server 4 via the communication network 6, it is received by the communication interface 4e. The transaction is then stored in RAM 4c by communication interface 4e or by CPU 4a. Then, in response to this, the CPU 4a starts the processing shown on the right side of FIG.

At step Sf1, the CPU 4a checks whether the transaction includes a terminal code. If the terminal code is included in the transaction, the CPU 4a proceeds from step Sf1 to step Sf2, otherwise proceeds from step Sf1 to step Sf3.

In step Sf2 or step Sf3, the CPU 4a adds the data record created based on the transaction to the transaction information file. Specifically, the CPU 4a creates a data record that includes the transaction serial number included in the transaction in the index and includes the transaction product information and the total amount as transaction information. In step Sf2, the CPU 4a includes the terminal code and transaction serial number included in the transaction in the index, but in step Sf3, both the terminal code and transaction serial number in the index are null values.

Thus, with the above processing, the transaction information file contains data records relating to each of the transactions carried out at the POS terminal 3, but the data records relating to the transactions collectively registered using the pre-registered ticket are It further includes the terminal code of the handy terminal 1 used to issue the pre-registration ticket and the transaction serial number related to the issuance of the pre-registration ticket. In other words, the transaction information file describes the terminal code and transaction serial number relating to the pre-registered ticket that has already been used. Therefore, in step Sd1, it can be confirmed whether or not the pre-registration ticket has been used.

As described above, according to the POS system 100, each pre-registered ticket can be identified by the terminal code and the transaction serial number, and by storing the terminal code and transaction serial number related to the used pre-registered ticket, each It is possible to determine whether or not the pre-registration ticket has been used. When the two-dimensional code of the used pre-registration ticket is scanned, the fact that the purchased product is already used is notified without registering the purchased product based on the PLU code represented by the two-dimensional code.

When the same pre-registration ticket is read a plurality of times, duplicate registration of the same purchased product is prevented. If such duplicate registration occurs, the cash register clerk must perform an operation to individually cancel the registration of the duplicately registered products, which is very time-consuming. According to this embodiment, such problems can be reliably avoided. Also, it is possible to prevent some kind of bad behavior caused by repeatedly using one pre-registered ticket.

This embodiment can be modified in various ways as follows.

The handy terminal 1 may be provided with a printing device 2d, and the pre-registration ticket may be printed using this printing device 2d. In this case, the portable printer 2 becomes unnecessary.

A pre-registration ticket may be realized using a recording medium other than paper, such as a rewrite card, magnetic card, or memory card. When using a rewritable card, it is conceivable to visibly record the two-dimensional code as in the above embodiment. When using a magnetic card or memory card, the information to be registered in the pre-registration ticket is magnetically recorded or electronically recorded. When a magnetic card or memory card is used, a device compatible with the recording method, such as a magnetic card reader or memory card reader, is used as the reading means.

A part or all of the processing of the product sales data may be performed by the CPU 4 a in the server 4 .

A device that performs the notification operation may be provided outside the POS terminal 3 .

A device for reading the information recorded on the pre-registered ticket may be provided outside the POS terminal 3 .

The CPU 3a of the POS terminal 3 may determine whether or not the pre-registration ticket has been used. In this case, data for managing whether or not each pre-registration ticket has been used may be stored in the server 4 as in the above-described embodiment, or may be stored in the POS terminal 3. .

Each pre-registration ticket can be used by adding the identification information of the pre-registration ticket to the database when the pre-registration ticket is issued, and deleting the identification information of the pre-registration ticket from the database when using the pre-registration ticket. You may manage whether it is done or not. Alternatively, when the pre-registration ticket is issued, the identification information of the pre-registration ticket and the status information indicating whether the identification information has been used are linked and added to the database, and when the pre-registration ticket is used, the pre-registration ticket Whether or not each pre-registration ticket has been used may be managed by updating status information associated with the identification information of the registration ticket.

The CPU 4a in the server 4 may perform the control of registering the purchased product based on the unused pre-registered ticket and not registering the purchased product based on the used pre-registered ticket.

The control for notifying that the pre-registration ticket has been used may be performed by the CPU 4 a of the server 4 .
