Description

Embodiments of the present invention relate to a transaction processing device and an information processing program.

Conventionally, in commercial facilities such as food supermarkets, a POS (Point of Sales) system is used that issues a receipt with a barcode at the time of payment when a product is traded, and when the product is returned, the barcode can be read to identify the product.

However, depending on the format of receipts that can be issued by the POS system and the width of the receipts, there are limitations on the number of digits that can be printed on the barcode, and barcodes with many digits may not be able to be printed. Methods to deal with such cases include printing the barcode in two lines or printing it as a QR code (registered trademark). Printing the barcode in two lines is time-consuming, as it requires the barcode to be read twice. Also, printing it as a QR code requires a scanner or other device capable of reading QR codes.

Japanese Patent Application Publication No. 4-347793

(Embodiment)
Hereinafter, the embodiments will be described with reference to the drawings. Note that the scale of each part in each drawing used in the following description of the embodiments may be changed as appropriate. Also, for the sake of explanation, each drawing used in the following description of the embodiments may omit configurations.

In the following, an example of a store that sells goods will be used for explanation. The store will be a brick-and-mortar store. Goods include not only tangible goods, but also non-tangible goods such as services or tickets. A service is a service provided to a customer. The store may be a store that primarily sells tangible goods, or a store that primarily sells the provision of services. For example, a store that primarily sells tangible goods includes, but is not limited to, a supermarket or a home improvement store. For example, a store that primarily sells the provision of services includes, but is not limited to, a restaurant or a sports gym.

A commodity transaction is the transfer of fees from a customer to a store in connection with the sale of the commodity by the store. From the store's perspective, the transaction involves the sale of a commodity. From the customer's perspective, the transaction involves the purchase of a commodity.

(Configuration example)
FIG. 1 is a block diagram illustrating a store system S.
The store system S is a system in a store X.

The store system S includes a POS terminal 1 and a store server 2. The POS terminal 1 and the store server 2 are connected to each other via a network NA so that they can communicate with each other freely. For example, the network NA is a LAN (Local Area Network). The network NA may include a wireless network or a wired network.

The store system S may include multiple POS terminals 1. The store system S may also refer to a system that includes at least two electronic devices.

Although FIG. 1 shows an example in which the store system S has two POS terminals 1, the number of POS terminals 1 is not limited to this. The configuration of the multiple POS terminals 1 may be the same as that of the POS terminal 1.

POS terminal 1 is a device that processes transactions at store X. For example, POS terminal 1 has a product registration function. POS terminal 1 uses the product registration function to process the registration of one or more products that are the subject of a transaction. Hereinafter, product registration is also referred to as product registration. Products that are the subject of a transaction are also referred to as trading products. Product registration is registering a product as a trading product. For example, product registration includes storing transaction data including data related to the trading product. The transaction data may include data related to the trading product for each trading product for one transaction. The data related to the trading product is data about the details of the trading product. The data related to the trading product may include a product code of the trading product. The product code of the trading product is identification information that can uniquely identify the trading product. The data related to the trading product may include a price of the trading product. The price of the trading product is the price per unit of the trading product. The data related to the trading product may include the number of trading products. The number of trading products is the number of trading products included in one transaction. The transaction data includes a transaction number. The transaction number is issued for each transaction. The transaction number is a code that can uniquely identify a transaction. The transaction data indicates data that links the transaction number with data related to the transaction product.

The transaction data is managed by a transaction code that can identify the transaction data. The transaction code is a code that can uniquely identify the transaction data. The transaction code is assigned to the transaction data. The transaction code is, for example, a transaction search code that can search the transaction data. The transaction code may be a combination of at least one piece of information that can identify one transaction. The information that can identify a transaction includes, for example, the transaction date and time, the store code, the terminal number, and the transaction number. Each piece of information that can identify a transaction may be a value indicated by a different number of digits. The transaction date and time is information about the transaction date and time. The transaction date and time may include information about the transaction year, month, and day when the transaction was performed. The store code is a code that can uniquely identify a store. The terminal number is a code that can uniquely identify the POS terminal 1. The transaction code is, for example, an 18-digit code consisting of "transaction year (2 digits), transaction month (2 digits), transaction date (2 digits), store code (4 digits), terminal number (4 digits), and transaction number (4 digits)". The information included in the transaction code is not limited to this. The number of digits of the transaction code is not limited to this. The transaction code is, for example, a code expressed in decimal.

The transaction data is stored, for example, in a transaction management server that manages each transaction. The transaction management server may be the store server 2 or a server on a different cloud.

For example, the POS terminal 1 has a payment function. The POS terminal 1 uses the payment function to process payment for a transaction based on data related to the transaction. Payment is payment for the transaction. Payment includes the meaning of accounting. Completion of payment by the POS terminal 1 includes the meaning of the completion of the transaction.

Payment methods for settling a transaction include offline payment and online payment. Offline payment is a payment that does not require the POS terminal 1 to link with other devices via a network. For example, offline payment is payment with cash, gift certificates, etc. Online payment is a payment that is carried out by the POS terminal 1 in cooperation with other devices via a network. For example, online payment is credit card payment, electronic money payment, debit card payment, code payment, etc.

The POS terminal 1 can be operated by a user of the POS terminal 1. The user of the POS terminal 1 is a store clerk or a customer. The store clerk or customer may be interpreted as a user or a person. The POS terminal 1 is an example of a transaction processing device. An example of the configuration of the POS terminal 1 will be described later.

The store server 2 is a device capable of communicating with the POS terminal 1 via the network NA. If the store system S has multiple POS terminals, the store server 2 is a device capable of communicating with multiple POS terminals, including the POS terminal 1, via the network NA. The store server 2 may be a server used in a cloud service.

The store server 2 is a device that stores information necessary for transactions in store X. The store server 2 stores product master data. The product master data includes various information about each product, such as product code, price, and product name. The store server 2 stores transaction data collected from at least one POS terminal 1. The store server 2 may store transaction data for store X and other stores. The store server 2 stores a code conversion program used to convert transaction codes.

The code conversion program is a program that converts the base of a transaction code. The code conversion program includes, for example, a method of converting base. The method of converting base includes, for example, the base of the source, the base of the destination, and the unit of the value to be converted. The method of converting base includes converting from a decimal number to an N-ary number (N is a number greater than 10). The N-ary number is, for example, a hexadecimal number or a 32-ary number. The method of converting base includes converting some or all of the digits of the transaction code to a base. Some of the digits of the transaction code are values that indicate part of the information that can identify the transaction data contained in the transaction code. For example, if the transaction code is an 18-digit value, the method of converting base includes converting the entire 18-digit value. The method of converting base includes converting only the 4-digit value that indicates the store code out of the 18-digit value. The method of converting base includes converting the 18-digit value as one unit if the transaction code is an 18-digit value. The base conversion method includes converting each value of the identifiable information into transaction data as one unit when the transaction year is a two-digit value, the transaction month is a two-digit value, the transaction date is a two-digit value, the store code is a four-digit value, the terminal number is a four-digit value, and the transaction number is a four-digit value. The base conversion method may convert all or part of each value of the identifiable information. For example, when all values of the identifiable information are converted, the converted transaction codes are all N-ary values. When only part of the values of the identifiable information are converted, the converted transaction codes are a mixture of decimal values and N-ary values.

The code conversion program includes a method of base conversion that converts (returns) the base-converted transaction code to the original base. In the following description, base conversion that converts to the original base is also referred to as inverse conversion. Inverse conversion includes conversion from an N-ary number to a decimal number. The inverse conversion method may be different depending on the method of base conversion.

An example of the configuration of the POS terminal 1 will be described.

The transaction code expressed in decimal is, for example, a numerical value expressed in decimal. The transaction code expressed in decimal is an example of a first transaction code. The transaction code expressed in N-ary is, for example, a numerical value expressed in a base greater than 10. The transaction code expressed in N-ary is an example of a second transaction code. The N-ary is, for example, hexadecimal or 32-ary. The number of digits of the transaction code expressed in N-ary is less than the number of digits of the transaction code expressed in decimal. For example, if the first transaction code expressed in decimal is 18 digits, the second transaction code expressed in 32-ary is 12 digits.

The conversion unit 103 converts a transaction code in which some or all of the digits are expressed in base N numbers into a transaction code expressed in base 10 numbers based on a code conversion program. For example, the conversion unit 103 converts a second transaction code expressed in base 32 numbers into a first transaction code expressed in base 10 numbers.

(Example of a barcode symbol)
The barcode symbol printed by the POS terminal 1 will now be described.
FIG. 3 is a diagram illustrating an example of a barcode symbol according to the embodiment.

3 shows an example of a receipt on which a barcode symbol is printed. Receipt Ra includes a barcode symbol display area Ara and a transaction code display area Arb.
The barcode symbol display area Ara is an area for displaying a barcode symbol, which indicates a transaction code converted into an N-ary number.
The transaction code display area Arb is an area for displaying a transaction code, which is expressed as a decimal number.

According to this example, the barcode symbol display area Ara displays an N-ary transaction code with fewer digits than a decimal transaction code, so that even if the size of the barcode symbol display area Ara is limited, a barcode symbol indicating a transaction code with many digits can be displayed. In addition, the transaction code display area Arb displays the decimal transaction code as numbers, so that the transaction code can be easily recognized when visually checking the transaction code. Therefore, when the user needs to manually input the transaction code, for example, when the barcode symbol cannot be read by a scanner, the transaction code can be input based on the decimal transaction code. The decimal transaction code corresponds to the transaction code before it is converted to an N-ary number.

(Example of operation)
The processing of the store system S will be described.
In the following description mainly focusing on the POS terminal 1, the POS terminal 1 may be read as the processing circuit 10. Similarly, in the following description mainly focusing on the store server 2, the store server 2 may be read as the processing circuit of the store server 2.

In the following process, it is assumed that a user of the POS terminal 1 registers a product. The transaction code is assumed to be a code of more than 16 digits. In the following process, it is assumed that the POS terminal 1 is unable to print a barcode symbol indicating a code of more than 16 digits on a receipt. For example, it is assumed that the width of the barcode symbol is larger than the width of the printable area on the receipt, and the barcode symbol cannot be printed along the width of the receipt.

The processing circuit 10 performs a product registration process (ACT1). ACT1 may be a process by the registration unit 101. In ACT1, for example, the processing circuit 10 registers a product based on a product registration operation by a user of the POS terminal 1. The product registration operation may include, for example, an operation of reading a code symbol attached to the product via the scanner 15. The product registration operation may include an operation of selecting a product registration button on a product registration image by touch input or the like. The processing circuit 10 acquires a product code recorded in the code symbol. The processing circuit 10 refers to the product master stored in the auxiliary storage device 12 and acquires data related to the product corresponding to the product code. The product corresponding to the product code is also called a transaction product. The data related to the transaction product includes data such as a product code, a product name, a product price, and a number of items. The processing circuit 10 generates transaction data including data related to the transaction product for each transaction. The processing circuit 10 may also refer to the product master stored in the store server 2 and acquire data related to the transaction product of the product corresponding to the product code.

The processing circuit 10 generates a transaction code based on the transaction data (ACT 2). ACT 2 may be processing by the registration unit 101. In ACT 2, for example, the processing circuit 10 generates a transaction code expressed in decimal based on information that can identify the transaction. In this example, the processing circuit 10 generates an 18-digit transaction code consisting of "transaction year (2 digits), transaction month (2 digits), transaction date (2 digits), store code (4 digits), terminal number (4 digits), and transaction number (4 digits)." The processing circuit 10 may link the transaction data and the transaction code and store them in the auxiliary storage device 12.

The processing circuit 10 performs payment processing (ACT 3). ACT 3 may be processing by the payment processing unit 102. In ACT 3, for example, the processing circuit 10 processes the payment of the transaction based on the transaction data using a payment function. The processing circuit 10 performs the payment processing of the transaction based on the payment method selected by the user.

The processing circuit 10 converts the transaction code expressed in decimal numbers into a transaction code in which some or all of the digits are expressed in N-ary numbers (ACT 4). ACT 4 may be processing by the conversion unit 103. In ACT 4, for example, the processing circuit 10 acquires a code conversion program from the code conversion program storage area 121. The processing circuit 10 converts the transaction code expressed in decimal numbers into a transaction code expressed in N-ary numbers based on the code conversion program. The processing circuit 10 may convert some of the digits of the transaction code into N-ary numbers. The processing circuit 10 may convert all of the digits of the transaction code into N-ary numbers. The processing circuit 10 may convert the transaction code into N-ary numbers, with all of the digits of the transaction code as one unit. The processing circuit 10 may convert the transaction code into N-ary numbers, with some of the digits of the transaction code as one unit. The number of digits of the transaction code converted into N-ary numbers by the processing circuit 10 is less than the number of digits of the transaction code expressed in decimal numbers. The processing circuit 10 may change the conversion method depending on the settings of the user of the POS terminal 1 or the store manager, etc.

The processing circuit 10 performs a process of printing a barcode symbol indicating the transaction code converted into an N-ary number on a medium (ACT 5). ACT 5 may be a process by the print processing unit 104. In ACT 5, for example, the processing circuit 10 generates a barcode symbol indicating the transaction code converted into an N-ary number. The processing circuit 10 outputs the generated barcode symbol to the printing device 18. Here, the barcode symbol includes the meaning of image data of the barcode symbol. The barcode symbol may be read as image data of the barcode symbol. The processing circuit 10 controls the printing device 18 to print the barcode symbol on a receipt. The printing device 18 prints the barcode symbol on the receipt. The processing circuit 10 may perform a process of printing the decimal transaction code as decimal numbers on a medium. The processing circuit 10 generates image data representing the decimal transaction code as decimal numbers. The processing circuit 10 outputs image data of the transaction code expressed in decimal numbers to the printing device 18. The processing circuit 10 controls the printing device 18 to print the image data of the transaction code expressed in decimal numbers on the receipt. The printing device 18 prints the transaction code in decimal numbers on the receipt.

The output unit 105 outputs the transaction data to the store server 2. The output unit 105 outputs the decimal transaction code to the store server 2. The store server 2 acquires the transaction data. The store server 2 acquires the transaction code.

The store server 2 links the transaction data with the transaction code and stores them (ACT 6).

The POS terminal 1 may also perform a process of converting a transaction code expressed in decimal to a transaction code in which some or all of the digits are expressed in N-ary based on a user operation. In this case, the POS terminal 1 may obtain a conversion instruction input by the user via the input device 16. The POS terminal 1 may perform the process of ACT 4 based on the conversion instruction.

In addition to or instead of printing a barcode symbol indicating a transaction code on a receipt, the POS terminal 1 may output image data of the barcode symbol to another device. The other device may be, for example, a user terminal such as a smartphone used by a customer.

According to this example, the POS terminal 1 can convert a decimal transaction code into an N-ary transaction code. The POS terminal 1 can print a barcode symbol representing the N-ary transaction code on a receipt. Therefore, the POS terminal 1 can reduce the number of digits of the transaction code by converting the decimal transaction code into an N-ary number that is greater than 10. The POS terminal 1 can print a barcode symbol representing the transaction code with the reduced number of digits on a receipt. For example, the POS terminal 1 can convert a transaction code represented by 18 decimal digits into a 32-ary number and convert it into a transaction code with fewer digits than 18 digits, so that even if the number of digits of the barcode that can be printed is limited by the width of the receipt, it can print a barcode symbol that fits within the limited number of digits. The POS terminal 1 can easily issue a barcode symbol representing a code with a large number of digits by printing a barcode symbol representing a base-converted transaction code on a receipt. In this way, the POS terminal 1 can easily process a barcode symbol representing a code with a large number of digits.

FIG. 5 is a sequence diagram illustrating an example of the procedure of information processing related to a transaction information search by the store system S according to the embodiment.
In the following process, it is assumed that a user of the POS terminal 1 searches for transaction data for a return process or the like. For example, the user of the POS terminal 1 receives from a customer a receipt that includes a barcode symbol indicating the transaction code of the transaction to be returned. The user of the POS terminal 1 reads the barcode symbol indicating the transaction code printed on the receipt with the scanner 15. It is assumed that the barcode symbol is a barcode symbol indicating the transaction code expressed in an N-ary number.

The processing circuit 10 acquires a transaction code (ACT 11). ACT 11 may be processing by the acquisition unit 106. In ACT 11, for example, the processing circuit 10 reads, via the scanner 15, a barcode symbol printed on a receipt, in which some or all of the digits indicate a transaction code expressed in an N-ary number. The processing circuit 10 acquires the transaction code recorded in the barcode symbol.

The processing circuit 10 converts a transaction code in which some or all of the digits are expressed in an N-ary number into a transaction code expressed in a decimal number (ACT 12). ACT 12 may be a process by the conversion unit 103. In ACT 12, for example, the processing circuit 10 converts the transaction code expressed in an N-ary number into a transaction code expressed in a decimal number based on a code conversion program. The processing circuit 10 may convert the transaction code expressed in an N-ary number into a transaction code expressed in a decimal number based on a reverse conversion method included in the code conversion program. The processing circuit 10 may perform a process of returning the transaction code expressed in an N-ary number to a transaction code expressed in a decimal number based on a base conversion method from a decimal number to an N-ary number.

The processing circuit 10 outputs the transaction code expressed in decimal to the store server 2. This processing may be performed by the search processing unit 107. The processing circuit 10 may output a search instruction to the store server 2. The store server 2 acquires the transaction code. The store server 2 may acquire the search instruction.

The store server 2 performs a search process to search for transaction data based on the acquired transaction code (ACT 13). In ACT 13, for example, the store server 2 refers to the transaction data stored in the store server 2 and acquires the transaction data corresponding to the transaction code as a search result. The store server 2 outputs the transaction data that is the search result to the POS terminal 1.

The processing circuit 10 acquires transaction data from the store server 2 (ACT 14). ACT 14 may be processing by the search processing unit 107.

The processing circuit 10 displays the transaction data on the display device 17 (ACT 15). ACT 15 may be processing by the display processing unit 108. In ACT 15, for example, the processing circuit 10 displays image data based on the transaction data on the display device 17.

According to this example, the POS terminal 1 can convert an N-ary transaction code into a decimal transaction code. The POS terminal 1 can search for transaction data corresponding to the transaction code based on the decimal transaction code. Therefore, even if the POS terminal 1 reads a code symbol indicating a transaction code expressed in N-ary, it can search for transaction data managed by a decimal transaction code. In this way, the POS terminal 1 can easily process barcode symbols indicating codes with a large number of digits.

According to the embodiment, the POS terminal 1 can convert a decimal transaction code into an N-ary transaction code (where N is a number greater than 10) and print a barcode symbol representing the N-ary transaction code on a receipt. This allows the POS terminal 1 to reduce the number of digits in the transaction code and the barcode symbol to be printed on a receipt. This allows the POS terminal 1 to easily issue a barcode symbol representing a code with a large number of digits.
The POS terminal 1 also outputs the decimal transaction code and the corresponding transaction data to the store server 2. The store server 2 can associate the decimal transaction code with the corresponding transaction data and store them. Therefore, the store server 2 does not need to manage the N-ary transaction code.
Furthermore, the POS terminal 1 converts the N-ary transaction code into a decimal transaction code and outputs the decimal transaction code to the store server 2. The POS terminal 1 can search for corresponding transaction data based on the decimal transaction code. Therefore, even if the POS terminal 1 reads a code symbol indicating a transaction code expressed in N-ary, it can search for transaction data managed by the decimal transaction code. In this way, the POS terminal 1 can easily process barcode symbols indicating codes with many digits.

Other Embodiments
The transaction processing device may be realized by a single device as explained by taking POS terminal 1 as an example, or may be realized by multiple devices with distributed functions.

In the above explanation, the POS terminal 1 that allows the user to complete the process from product registration to payment has been taken as an example, but is not limited to this. The POS terminal 1 may be a shopping cart system with a product registration function. The POS terminal 1 may be a smartphone POS terminal that allows the customer to register products using a mobile terminal that the customer owns. In these cases, the payment device that performs the payment process may realize functions other than the product registration function among the functions provided by the processing circuit 10 of the POS terminal 1.

When the functions of the POS terminal 1 are provided in a cloud server, the functions of the POS terminal 1 may be realized by a system including a tablet terminal communicably connected to the cloud server. The store server 2 communicates with the cloud server and obtains transaction codes and transaction data from the cloud server instead of the POS terminal 1.
