Description

Embodiments of the present invention relate to a transaction data processing device and a transaction data processing method .

Originally, a transaction data processing device such as a POS (point-of-sale) terminal issues a receipt (hereinafter referred to as a paper receipt) in which necessary items are printed on a receipt paper after the settlement is completed.

On the other hand, in recent years, introduction of an electronic receipt system that allows a user to view electronic receipt data (hereinafter, referred to as electronic receipt data) on an arbitrary information terminal has been advanced.
In the transaction data processing device belonging to this electronic receipt system, conventionally, print data for issuing a paper receipt is first generated. Then, the transaction data processing device analyzes the print data to extract the information to be included in the electronic receipt data, and indicates what the information is based on the position of the information on the paper receipt. Determine the distinguished name. Further, the transaction data processing device generates electronic receipt data as data representing the association between the extracted information and the identification name determined for the information.
By doing so, even with respect to the conventional transaction data processing device configured to issue a paper receipt, it is possible to add an electronic receipt system to the electronic receipt system only by adding the function of generating the electronic receipt data from the print data by the above processing. It becomes possible to respond. The function is realized by causing a processor that controls the transaction data processing device to execute an application program. The function is called, for example, an electronic receipt agent. The application program described above is called, for example, an agent program.

However, when the electronic receipt data is generated by the above processing, the relationship between the position where the information is indicated on the paper receipt and the identification name of the information needs to be clear in advance. That is, the processing by the electronic receipt agent differs depending on the format of the paper receipt represented by the print data to be processed. In order to cope with such differences in transaction data processing specifications, it was necessary to prepare separate agent programs.
Under such circumstances, it has been desired that a common agent program can be applied regardless of the difference in transaction data processing specifications.

The figure which shows an example of the data for exchanges. 3 is a flowchart showing a processing procedure of the processor in FIG. 1 in the electronic receipt API processing. 2 is a flowchart showing a processing procedure of a processor in FIG. 1 in electronic receipt agent processing.

Hereinafter, an example of an embodiment will be described with reference to the drawings. In the present embodiment, a POS terminal will be described as an example of a transaction data processing device that processes product sales. However, the transaction to be processed is not limited to the sale of goods, but may be the provision of services.
FIG. 1 is a block diagram showing a circuit configuration of essential parts of a POS terminal according to this embodiment.
FIG. 1 shows an electronic receipt system including POS terminals 101 and 102 and a receipt server 103. Data communication is possible between the POS terminals 101 and 102 and the receipt server 103 via the communication network 200.

It is assumed that the POS terminals 101 and 102 have different transaction data processing specifications, and are manufactured by different manufacturers (company A and company B) independently of each other in this embodiment. However, FIG. 1 shows only the basic configuration of the POS terminals 101 and 102, and most of the basic configurations are common regardless of the difference in transaction data processing specifications. Therefore, in FIG. 1, elements having the same function among the constituent elements of the POS terminals 101 and 102 are denoted by the same reference numerals. However, the elements denoted by the same reference numerals respectively included in the POS terminals 101 and 102 do not indicate that they are the same device, and in many cases, different devices are used.

The POS terminals 101 and 102 include a processor 1, a main memory 2, an auxiliary storage device 3, a clock unit 4, an input device 5, a display device 6, a bar code reader 7, a printer 8, a communication interface 9 and a transmission line 10. The processor 1, the main memory 2, the auxiliary storage device 3, the clock unit 4, the input device 5, the display device 6, the bar code reader 7, the printer 8 and the communication interface 9 include an address bus, a data bus, a control signal line, and the like. They are connected by a transmission line 10 including the same.

In the POS terminals 101 and 102, the processor 1, the main memory 2, and the auxiliary storage device 3 are connected by the transmission path 10 to form a computer that controls the POS terminals 101 and 102.

The processor 1 corresponds to the central part of the computer. The processor 1 controls each unit to realize various functions as the POS terminals 101 and 102 according to an operating system and an application program.

The main memory 2 corresponds to the main storage part of the computer. The main memory 2 includes a non-volatile memory area and a volatile memory area. The main memory 2 stores an operating system and application programs in a non-volatile memory area. The main memory 2 may also store data necessary for the processor 1 to execute processing for controlling each unit in a non-volatile or volatile memory area. The main memory 2 uses a volatile memory area as a work area in which data is appropriately rewritten by the processor 1. The volatile memory area includes a so-called registration processing area for storing a purchased product list.

The auxiliary storage device 3 corresponds to the auxiliary storage part of the computer. The auxiliary storage device 3 is, for example, an EEPROM (electric erasable programmable read-only memory), an HDD (hard disc drive), an SSD (solid state drive), or the like. The auxiliary storage device 3 stores data used by the processor 1 in performing various processes and data generated by the process in the processor 1. The auxiliary storage device 3 stores an application program. The auxiliary storage device 3 stores program components accompanying the application program.

The programs stored in the auxiliary storage device 3 of the POS terminal 101 include a control program P1, an API program P2, and an agent program P3.
The control program P1 is an application program. The control program P1 describes control processing for various operations related to transaction data processing.
The API program P2 is a program component accompanying the control program P1. The API program P2 is realized as a program file in the OCX (OLE control extension) format, for example. The API program P2 is called by the control processing for transaction data processing based on the control program P1 and executed by the processor 1, thereby providing an application programming interface (API) to the control processing. .. The API provided by the API program P2 enables the later-described processing by the agent program P3 to be used by the above control processing.
The agent program P3 is an application program. The agent program P3 describes a process for generating electronic receipt data as data including a plurality of data sets given via the API from the transaction data process based on the control program P1 and transmitting it to the receipt server 103.

The programs stored in the auxiliary storage device 3 of the POS terminal 102 include a control program P4, an API program P2, and an agent program P3.
That is, in the POS terminal 102, the auxiliary storage device 3 stores the same API program P2 and agent program P3 as the POS terminal 101, but does not store the control program P1 and instead stores the control program P4.
The control program P4 is an application program. The control program P4 describes control processing for various operations related to transaction data processing.

The control program P1 is created by an arbitrary creator on the assumption that the POS terminal 101 manufactured by A company is used under the management of A company. The control program P4 is created by an arbitrary creator on the assumption that the POS terminal 102 manufactured by B company is used under the management of B company. The API program P2 and the agent program P3 are created by an arbitrary creator under the management of a service provider who provides an electronic receipt service by the receipt server 103, for example.

Transfer of the POS terminals 101 and 102 is generally performed with the control programs P1 and P4 stored in the auxiliary storage device 3. In this case, the control programs P1 and P4 may be stored in the main memory 2. However, the POS terminals 101, 102 may be transferred in a state where the control programs P1, P4 are not stored in the main memory 2 or the auxiliary storage device 3. In this case, the control programs P1 and P4 are transferred by being recorded on a removable recording medium such as a magnetic disk, a magneto-optical disk, an optical disk, a semiconductor memory. Alternatively, the control programs P1 and P4 are transferred via the network. Then, the control programs P1 and P4 may be written in the main memory 2 or the auxiliary storage device 3 of the separately transferred POS terminals 101 and 102.

The API program P2 and the agent program P3 are typically not stored in the auxiliary storage device 3 when the POS terminals 101 and 102 are transferred. The API program P2 and the agent program P3 are downloaded to the POS terminals 101 and 102 from the receipt server 103 or another server via the communication network 200, for example, and written in the auxiliary storage device 3. However, the API program P2 and the agent program P3 may be transferred by being recorded in a removable recording medium such as a magnetic disk, a magneto-optical disk, an optical disk, a semiconductor memory or the like. Alternatively, the transfer of the POS terminals 101 and 102 may be performed in a state where the API program P2 and the agent program P3 are stored in the auxiliary storage device 3. In this case, the API program P2 and the agent program P3 may be stored in the main memory 2.

The clock unit 4 constantly performs a timekeeping operation and outputs date and time information representing the current date and time.
The input device 5 receives an operation by the operator and outputs input information according to the operation. As the input device 5, for example, a keyboard, a mouse, a touch panel or the like can be used.
The display device 6 displays an image representing various information to be presented to the operator. As the display device 6, for example, an LCD (liquid crystal display) or a touch panel can be used.

The barcode reader 7 reads a barcode representing a member code for identifying a member of the smart receipt service. The barcode is typically displayed on a display unit mounted on the information terminal owned by the member. The bar code reader 7 may be shared with a device for reading a bar code which is displayed on a product and identifies a product and which represents a product code, or a device for that purpose is provided separately from the bar code reader 7. Good.
The printer 8 prints various character strings and images on the receipt paper. Then, the printer 8 issues the receipt by ejecting the printed receipt paper to the outside of the POS terminals 101 and 102. As the printer 8, for example, a thermal printer or a dot impact printer can be used.
The communication interface 9 performs data communication via the communication network 200. That is, the communication interface 9 is an example of a communication device.

Next, the operation of the POS terminal 101 configured as above will be described. Note that the contents of the processes described below are examples, and the order of the processes may be appropriately changed or other processes may be added as long as the same result can be obtained. ..
When the POS terminal 101 is activated in the operation mode in which transaction data processing should be performed, the processor 1 starts control processing according to the control program P1. The transaction data processing unit is realized by the processor 1 executing this control processing.

FIG. 2 is a flowchart of control processing by the processor 1 of the POS terminal 101.
In ACT1, the processor 1 confirms whether or not the registration operation by the operator is started. Then, if the corresponding operation is not performed, the processor 1 determines No, and proceeds to Act 2.
In ACT2, the processor 1 confirms whether or not the member code is scanned. Then, the processor 1 determines No if the member code is not scanned, and returns to Act 1.
Thus, processor 1 waits in Act1 and Act2 for registration to begin or the membership code to be scanned.

The operator holds the bar code representing the member code over the bar code reader 7 before performing the registration operation regarding the commercial transaction for which the electronic receipt service is desired to be applied. Then, the barcode reader 7 scans the barcode and extracts the member code from the barcode. In response to this, the processor 1 determines Yes in Act 2, and proceeds to Act 3.
In Act 3, the processor 1 causes the main memory 2 to store the membership code extracted by the barcode reader 7 in the auxiliary storage device 3. Then, after this, the processor 1 returns to the standby state of Act1 and Act2. When the processor 1 proceeds to Act 3 again in response to the membership code being scanned again, the processor 1 uses the membership code stored in the main memory 2 or the auxiliary storage device 3 as the newly extracted membership code. To overwrite.
As described above, in this embodiment, the member code is acquired before the start of product registration, and the member code is not acquired after the start of product registration. However, the processor 1 may obtain the membership code even during the product registration.

If the operator starts registration, the operator performs a registration operation regarding the purchased merchandise subject to the commercial transaction. Then, if the registration operation is performed in the standby state of Act1 and Act2, the processor 1 determines Yes in Act1, and proceeds to Act4.
In ACT4, the processor 1 performs registration processing and accounting processing. The registration process is a process of registering the product purchased by the shopper in the purchased product list. As the registration process, it is possible to use the same process as that performed by the ready-made POS terminal. Accounting processing includes account processing and settlement processing. The billing process is a process of calculating the price of a product registered in the purchased product list. The settlement process is a process of settling the price. As the accounting process, it is possible to use the same process as that performed by a ready-made POS terminal. Both the registration process and the accounting process are one of data processes related to transaction of goods. Thus, by the control processing based on the control program P1 being executed by the processor 1, the computer having the processor 1 as a central part functions as a processing means for performing data processing relating to transaction of goods.

In Act 5, the processor 1 generates transaction data. The transaction data includes data collected by a POS server (not shown). What kind of data is specifically included in the transaction data is arbitrary, and may be determined by, for example, the designer of the control program representing the control process shown in FIG. 2 or the administrator of the POS terminal 101. The processor 1 may immediately transmit the transaction data generated here to the POS server or the like, or may transmit the transaction data accumulated in the auxiliary storage device 3 to the POS server or the like at an arbitrary timing thereafter. ..

In ACT6, the processor 1 generates journal data. The journal data is data for confirming the history of commercial transactions processed by the POS terminal 101. What data is specifically included in the journal data is arbitrary, and may be determined by, for example, the designer of the control program representing the control process shown in FIG. 2 or the administrator of the POS terminal 101. The journal data may be printed and recorded on a journal sheet, or may be stored as electronic data as it is. The journal data as electronic data is typically stored in the auxiliary storage device 3. However, the journal data may be stored in the POS server or recorded in a portable storage medium.

In Act 7, the processor 1 confirms whether the shopper is a member of the electronic receipt service. Then, the processor 1 determines No when the member code is not stored in Act 3 in the main memory 2 or the auxiliary storage device 3, and proceeds to Act 8.
In ACT8, the processor 1 generates print data for printing the character string representing the transaction content on the receipt paper based on the list of purchased products and the result of the settlement process.
In ACT 9, the processor 1 sends the above print data to the printer 8 and causes the printer 8 to print according to the print data, thereby issuing a paper receipt. Then, the processor 1 thereafter ends the control processing shown in FIG.

On the other hand, if the membership code is stored in Act 3 in the main memory 2 or the auxiliary storage device 3, the processor 1 determines Yes in Act 7, and proceeds to Act 10.
In ACT10, the processor 1 generates exchange data. The exchange data is data including a data set in a predetermined format in which information to be displayed on an electronic receipt regarding this commercial transaction is associated with an identification name indicating what kind of information the information is. .. The exchange data is data for passing a data set to the electronic receipt agent process based on the agent program P3 via the API provided by the API program P2. Therefore, the processor 1 sets the data format of the exchange data to the data format defined by the API. The data format may be arbitrarily determined by a service provider of the electronic receipt service, but it is assumed that the data format is, for example, JSON (JavaScript object notation) format (“JavaScript” is a registered trademark). The processor 1 also uses the identification name included in the exchange data from those defined by the API. The identification name is, for example, a member ID, a company ID, a store ID, a date/time, a cashier No., a header, a product name, a price, a classification, a receipt No., or the like. Information related to a member code, a company code, a store code, a transaction date and time, a cashier number, a header, a product name, a unit price, a classification code, and a transaction receipt number is associated with these identification names. The processor 1 saves the generated replacement data in the auxiliary storage device 3 with the file name defined by the API. It should be noted that various definitions in the API are determined by a service provider of the electronic receipt service, and are disclosed to manufacturers such as the POS terminals 101 and 102.

FIG. 3 is a diagram showing an example of exchange data.
In the exchange data shown in FIG. 3, a character string located between two double quotes indicates an identification name. Then, a character string representing the information associated with the identification name is shown after the colon. Accordingly, the exchange data shown in FIG. 3 represents a data set indicating that the information related to the identification name “member ID” is “1”, for example.

In Act 11, the processor 1 calls the API program P2 to instruct the transmission of a plurality of data sets included in the exchange data, and executes the electronic receipt API processing according to the API program P2. The command for calling the API program P2 is published as the definition of the API. Thus, the processor having the processor 1 as a central part functions as the first instructing means by the processor 1 executing the control processing based on the control program P1.

FIG. 4 is a flowchart showing a processing procedure of the processor 1 in the electronic receipt API processing. The API is realized by the processor 1 executing this processing.
In ACT21, the processor 1 activates the electronic receipt agent. The command to activate the electronic receipt agent is not published. When the electronic receipt agent is activated by the electronic receipt API processing, the processor 1 executes the electronic receipt agent processing based on the agent program P3 in a thread different from the control processing shown in FIG. 2 and the electronic receipt API processing shown in FIG. To do.

FIG. 5 is a flowchart showing the processing procedure of the processor 1 in the electronic receipt agent processing. The electronic receipt agent is realized by the processor 1 executing this control process.
In ACT31, the processor 1 generates electronic receipt data. Specifically, the processor 1 reads out the replacement data stored in the auxiliary storage device 3 in Act 10 of FIG. Then, the processor 1 generates electronic receipt data as data of a predetermined format including each data set included in the exchange data and data to be transmitted to the receipt server 103 via the communication network 200. .. Thus, the processor having the processor 1 as a central part functions as a generating means by the processor 1 executing the control processing based on the agent program P3.
At this time, the processor 1 may perform processing such as rearranging the order of the data sets into a predetermined order or checking whether or not the essential data sets are correctly included.

In Act 32, the processor 1 instructs the communication interface 9 to transmit the electronic receipt data generated as described above. In response to this instruction, the communication interface 9 sends the corresponding electronic receipt data to the communication network 200. Thus, the processor having the processor 1 as a central part functions as the transmission control means by the processor 1 executing the control processing based on the agent program P3. Activating the electronic receipt agent is equivalent to instructing such transmission. From this, when the processor 1 executes the control process based on the API program P2, the computer having the processor 1 as a central part functions as the second instruction means.
Then, the electronic receipt data is transmitted to the receipt server 103 via the communication network 200. The receipt server 103 manages the electronic receipt database by storing the receipt server 103 in a built-in or externally attached storage device. The electronic receipt database stores the information contained in a large number of electronic receipt data in association with the same identification name as defined by the API. When the receipt server 103 receives the electronic receipt data, the receipt server 103 registers the information associated with the identification name in the data set in the electronic receipt database as the information associated with the identification name. When the receipt server 103 is accessed from any information terminal (not shown) and is instructed to provide the electronic receipt screen, the receipt server 103 generates data representing the electronic receipt screen based on the electronic receipt database, and uses the data to generate the data. Send to. The process in the receipt server 103 at this time may be, for example, a well-known process performed in another existing receipt server.

When the processor 1 completes the transmission of the electronic receipt data in Act 32, the process proceeds to Act 33.
In Act 33, the processor 1 notifies the electronic receipt API process of the completion of transmission. Then, the processor 1 ends the electronic receipt agent process shown in FIG.

In the electronic receipt API processing shown in FIG. 4, the processor 1 activates the electronic receipt agent in Act 21, and then proceeds to Act 22.
In ACT22, the processor 1 waits for the completion of the transmission of the electronic receipt data. Then, the processor 1 determines Yes when the transmission completion is notified from the electronic receipt agent processing as described above, and ends the electronic receipt API processing shown in FIG. Then, the processor 1 also ends the control process shown in FIG.

On the other hand, the processor 1 of the POS terminal 102 performs control processing based on the control program P4. Since the control program P4 is different from the control program P1, the control process based on the control program P4 is not the same as the control process shown in FIG. 2 based on the control program P1. However, typically, the control process based on the control program P4 is generally similar to the control process shown in FIG. However, the contents and formats of the transaction data and journal data generated by the control processing are different in both control processing. Further, the content and format of the paper receipt when issuing the paper receipt are different in both control processes.

Since the API program P2 and the agent program P3 are the same in both the POS terminals 101 and 102, the processor 1 of the POS terminal 102 also executes Act10 and Act11 in FIG. 2 in the same manner as described above. Accordingly, the processor 1 of the POS terminal 102 executes the electronic receipt API processing and the electronic receipt agent processing based on the API program P2 and the agent program P3 in the same manner as described above. However, the exchange data need only comply with the definition in the API, and the exchange data generated by the POS terminals 101 and 102 need not have the completely same format.

As described above, the POS terminals 101 and 102 use the common electronic receipt API to exchange data according to the definition in the electronic receipt API from the control processing that controls the main functions related to the transaction data processing. To the electronic receipt agent. Then, the generation of electronic receipt data from the exchange data and the transmission of the electronic receipt data to the receipt server 103 are processed by a common electronic receipt agent. Therefore, an agent program adapted to the transaction data processing specifications is unnecessary.

The control programs P1 and P4 need to be configured to generate exchange data and pass the exchange data to the electronic receipt agent. However, for the exchange data, arbitrary information may be associated with the identification name defined by the electronic receipt API, and the electronic receipt API may be used for passing the exchange data. Therefore, the description in the control programs P1 and P4 relating to the generation and delivery of the exchange data may be simple, and the increase in the labor required to create the control programs P1 and P4 is small.

This embodiment can be variously modified as follows.
The transaction data processing device such as a cash register other than the POS terminal can be implemented in the same manner as the above embodiment.
Further, it can be realized as a device that performs at least one of an accounting process and a settlement process for a product that is registered for purchase by another registration device. As an example, the transaction data processing device can be realized as a web server. Specifically, the purchase registration is performed by an information terminal that a web server can communicate with via a communication network, and at least one of account processing and settlement processing, exchange data generation, electronic receipt API processing, and electronic receipt agent processing. And a web server.
