Description

  The present invention relates to a POS (Point Of Sales) system, a registration device, and a payment device that are used in retail stores and the like to register a product purchased by a customer and execute payment.

  In retail stores such as supermarkets, paying attention to the fact that the processing time at the cash register is longer than the merchandise registration as a means of eliminating the cash register queue at the time of customer congestion, the cash register is used as a registration device and a payment device. An accounting system that separates and arranges a larger number of registration apparatuses has been considered (see Patent Document 1).

  However, in such a system, it is necessary to provide a mechanism for reliably delivering the transaction data of the customer whose product registration has been completed to the checkout device. However, in Patent Document 1, the registration device prints the customer code on a temporary receipt as a barcode, and the customer The code and the transaction data are transferred to the settlement apparatus, and the settlement apparatus reads the customer code from the bar code on the temporary receipt, reads the transaction data of the customer, and performs payment settlement.

Japanese Patent Laid-Open No. 2-184959

  However, this method is based on the premise that there is no communication problem, but at present, communication problems often occur. In this case, the store is not only confused but also related to the credit of the store. was there.

  The present invention has been made in view of the above points. A registration device for confirming transaction data including details of a product purchased by a customer, and a receipt printed with details based on the determined transaction data. An object of the present invention is to provide a POS system that can execute price settlement even when a communication trouble occurs between the apparatuses in a POS system having a settlement apparatus that executes price settlement accompanied by issuance.

The present invention has been made to solve the above-described problem, and performs registration of a product by reading product data attached to the product, and a registration device for determining transaction data including the details of the product, and a confirmation A POS system having a settlement device that executes payment settlement with the issuance of a receipt on which the details are printed based on the transaction data, the registration device stores the transaction data associated with the transaction number When the communication determination unit determines that the state of the transmission unit to be transmitted to the external device, the communication determination unit for determining whether the state of the transmission unit is good, and the communication determination unit determines that the state is good, the transaction number is converted into a first code. When the communication determination unit determines that the slip is issued and the communication determination unit determines that the state is negative, the transaction data is converted into the second code, and the second code is printed. An issuance unit that issues a slip, and the settlement apparatus is capable of reading the first code and the second code printed on the slip, and the slip code represented by the first code A receiving unit that receives transaction data associated with the transaction number transmitted from the transmitting unit based on a transaction number, and a reading that determines whether the code read by the slip reading unit is the second code When the determination unit and the reading determination unit determine that it is not the second code, the price adjustment is executed based on the transaction data received by the receiving unit, and when the second code is the reading determination unit And a control unit that executes the payment settlement based on the second code when the determination is made.
As a result, the POS system reads the code representing the transaction data from the slip when a communication trouble occurs between the devices, so that even if a communication trouble occurs between the devices, the payment can be performed.
In addition, when a communication trouble occurs between the devices, the POS system quickly switches between the payment settlement using the first code and the payment settlement using the second code according to the communication state between the devices. For this reason, even if a communication trouble occurs between devices, the customer is not confused.
In addition, the operation performed by the customer does not change between the payment using the first code and the payment using the second code. For this reason, even if a communication trouble occurs between devices, the customer is not confused.

In the present invention, the first code is a bar code, and the second code is a two-dimensional code.
As a result, the price settlement using the two-dimensional code that takes a longer time to read than when reading the bar code is executed only when a communication trouble occurs between the apparatuses. For this reason, the POS system can promptly perform payment settlement as a whole.

  The present invention also provides a registration apparatus for registering merchandise by reading merchandise data attached to a merchandise and determining transaction data including the details of the merchandise, and transferring the transaction data associated with the transaction number to an external device. When the transmission determination unit determines that the state of the transmission unit is good and the communication determination unit determines that the state is good, the transaction number is converted into a first code, When a slip printed with the first code is issued and the communication determination unit determines that the state is negative, the transaction data is converted into a second code, and the slip printed with the second code is And a issuing unit that issues the registration unit.

  In addition, the present invention provides a payment apparatus that executes payment settlement with the issuance of a receipt printed with details based on transaction data determined by the registration apparatus. The first code and the second code printed on the slip are A slip reading unit that can be read, a receiving unit that receives transaction data associated with a transaction number from the registration device or an external device based on the first code, and a code read by the slip reading unit When the reading determination unit determines whether or not it is the second code, and when the reading determination unit determines that it is not the second code, the payment adjustment is executed based on the transaction data received by the receiving unit. When the reading determination unit determines that the code is the second code, the payment device includes a control unit that executes the payment adjustment based on the second code.

  According to the present invention, even if the registration device and the checkout device are separated, if a communication trouble occurs between the devices, the POS system automatically detects the transaction data and reads the transaction data from the slip. Therefore, even when a communication trouble occurs between the devices, it is possible to execute payment settlement. In addition, in either case, it is not necessary to change the operation method, so confusion can be reduced.

  An embodiment of the present invention will be described in detail with reference to the drawings. FIG. 1 is a perspective view showing that the POS system is operating. The POS system 100 is installed on the store floor. The POS system 100 includes a product registration device 10, a checkout device 20, and a store controller 30.

  The product registration device 10 is installed in the product registration counter 11. Further, the settlement apparatus 20 is installed in the settlement counter 21. Here, the number of installations of the merchandise registration apparatus 10 and the settlement apparatus 20 shown in FIG. 1 is an example. These numbers of installations may be determined according to the scale and cost of the store, for example. The store controller 30 (not shown in FIG. 1) is installed in the store's backyard.

  The operator S (clerk) operates the product registration device 10 to cause the product registration device 10 to issue a slip by causing the product registration device 10 to read the product data attached to the product purchased by the customer C.

  The customer C receives the issued slip, moves to the place where the checkout device 20 is installed, and causes the checkout device 20 to read the code printed on the slip, so that the checkout device 20 pays the bill. Let it run.

  FIG. 2 is a block diagram showing the configuration of the POS system. The store controller 30 and each product registration device 10a are connected to each other via a LAN (Local Area Network) 40 so that they can communicate with each other. Further, the store controller 30 and each checkout device 20a are communicably connected via the LAN 40.

  Since each product registration device 10a has the same configuration, the product registration device 10a will be referred to as a product registration device 10 below. In addition, since each settlement apparatus 20a has the same configuration, the settlement apparatus 20a is referred to as a settlement apparatus 20 below.

First, the store controller will be described.
The store controller 30 is a computer (server). The store controller 30 includes a store controller storage unit (not shown) and a store controller communication unit (not shown).

  The store controller storage unit stores the product data file. Here, the product data file is a data file including data on products handled by the store, and is, for example, a data file (data table) in which product names (product numbers) and sales prices are associated with each other.

  The store controller storage unit stores a large number of transaction data and transaction numbers associated with the transaction data as log files. Here, the transaction data is data including the details of the product (purchased product) purchased by the customer. The transaction data will be described later with reference to FIG.

  The store controller communication unit supplies the product data file updated according to the sales status and purchase status of the product to each product registration device 10 and each checkout device 20. Here, the store controller communication unit may supply the updated product data file with a frequency of once a day.

  The store controller communication unit receives transaction data from the product registration device 10 and stores the received transaction data in a log file of the store controller storage unit. Further, the store controller communication unit receives the transaction number from the settlement apparatus 20, acquires the transaction data associated with the received transaction number from the store controller storage unit, and transmits the acquired transaction data to the transaction number. It returns to the settlement apparatus 20.

Next, the product registration apparatus will be described.
The merchandise registration apparatus 10 is operated by the operator S (see FIG. 1) and reads the merchandise data attached to the merchandise purchased by the customer C (see FIG. 1), so that transaction data including the details of those merchandise is obtained. And register with the store controller 30.

  Further, the merchandise registration apparatus 10 can select either a barcode (for example, a JAN (Japan Article Number) code) or a two-dimensional code (for example, a QR code (registered trademark)) depending on whether the communication state of the store controller 30 is good or bad. This is printed on a paper medium, and a slip is issued by discharging the paper medium. The customer C receives the issued slip and causes the settlement apparatus 20 to read the barcode or two-dimensional code printed on the slip, thereby causing the settlement apparatus 20 to execute the payment settlement.

  FIG. 3 is a block diagram showing the configuration of the product registration apparatus. The merchandise registration apparatus 10 includes a CPU (Central Processing Unit) 101, a ROM (Read Only Memory) 102, a RAM (Random Access Memory) 103, a scanner unit 104, a store clerk display unit 105, and a customer display unit 106. A hard disk 107, a store clerk operation unit 108, a communication unit 109, a buzzer 110, a printing unit 111, and a bus 112. These are connected to each other via a bus 112.

  The ROM 102 stores a product registration program for causing the CPU 101 to execute a product registration process. The ROM 102 stores a device number for identifying the device itself.

  The scanner unit 104 optically reads the product data attached to the product by the operation of the operator S, and stores the read product data in the RAM 103. Further, the scanner unit 104 optically reads a person-in-charge name (person-in-charge number) for identifying the operator S from a name tag or the like, and stores the read person-in-charge name in the RAM 103.

A product registration program read from the ROM 102 is expanded in the RAM 103.
In addition, the RAM 103 temporarily stores various variables and data (for example, product data read by the scanner unit 104 and a person in charge name) generated by executing the product registration program.

  The RAM 103 temporarily stores transaction data (described later with reference to FIG. 4) in the processing area. Further, the RAM 103 additionally stores transaction data determined by product registration in a log file. The RAM 103 may continue to store the confirmed transaction data, for example, on the transaction day. Further, the RAM 103 may store a product data file supplied from the store controller 30 connected via the communication unit 109.

  The CPU 101 reads the product registration program stored in the ROM 102, expands it in the RAM 103, and executes the steps of the expanded product registration program, thereby controlling the product registration apparatus 10 as a whole.

  The CPU 101 (writing unit) determines a transaction number before causing the printing unit 111 to print a slip. Here, the transaction number is a number composed of the device number of the own device and a unique number (for example, a serial number) determined for each transaction in which the customer C purchases a product. For example, the transaction number is a number “01123” composed of a device number “01” followed by a unique number “123”. The CPU 101 associates the transaction data including the details of the product purchased by the customer with the transaction number, and transmits it to the store controller 30 via the communication unit 109. Thereby, the confirmed transaction data and transaction number are stored in the store controller 30.

  FIG. 4 shows an example of transaction data for one transaction. The item of transaction data includes a device number, a person in charge name, a transaction date and time, a transaction number associated with the transaction data, a total amount, a product name (product number), and the number of purchases.

  Here, the device number is an identification number indicating the product registration device 10 that has registered the product, that is, the product registration device 10 that has executed the transaction. The person-in-charge name is the name of the operator S (see FIG. 1) who operates the product registration apparatus 10 indicated by the apparatus number. The transaction date and time represents the date and time when the product was registered, that is, the date and time when the transaction was made. First, these items are first written in the transaction data for one transaction. In this case, since the other items are not yet registered, the transaction data is not finalized.

  The transaction number is a number composed of a device number and a number unique to each transaction. The product name (product number) is the name (number) of the product purchased by the customer C. The number of purchases is the number of each product purchased by the customer C. The CPU 101 calculates a subtotal amount (an amount obtained by multiplying the sales price and the number of purchases) and a total amount based on the product name (product number) and the number of purchases and the product data file stored in the RAM 103. When the registration of all purchased products is completed, the CPU 101 finalizes the transaction data by writing the transaction number and the total amount in the transaction data.

  Returning to FIG. 3, the description of the merchandise registration apparatus will be continued. The CPU 101 (communication determination unit) determines the presence / absence of a state in which the settlement apparatus can obtain transaction data through communication. For example, when the communication state between the own device and the store controller 30 is good, the CPU 101 determines that the operation of the common LAN 40 is normal and the payment device can obtain transaction data by communication.

  When the CPU 101 (control unit) determines that the payment apparatus is in a state where transaction data can be obtained through communication, the transaction number is converted into a barcode, and a slip printed with a barcode representing the transaction number is printed. Issued to part 111. On the other hand, the CPU 101 converts the determined transaction data stored in the RAM 103 into a two-dimensional code when it is determined that the settlement apparatus cannot obtain transaction data by communication, that is, the state is not good. . The CPU 101 controls the printing unit 111 and issues a slip by printing this two-dimensional code on a paper medium.

  FIG. 5 shows an example of a slip. FIG. 5A shows an example of a slip printed with a barcode. On this slip, transaction date and time, transaction number, number of pieces, and barcode are printed. FIG. 5B shows an example of a slip on which a two-dimensional code is printed. On this slip, transaction date and time, transaction number, number of pieces, and two-dimensional code are printed. The customer C (see FIG. 1) receives the issued slip of FIG. 5A or 5B, and causes the checkout apparatus 20 to read the barcode or two-dimensional code printed on the slip. Note that a plurality of two-dimensional codes may be printed on one slip shown in FIG. 5B according to the amount of transaction data.

Returning to FIG. 3, the description of the merchandise registration apparatus will be continued. When the scanner unit 104 scans the barcode printed on the slip by the operation of the operator S, the CPU 101 converts the transaction data associated with the transaction number represented by the barcode into a two-dimensional code.
The CPU 101 issues a slip on which the two-dimensional code is printed from the printing unit 111 based on the confirmed transaction data. Further, when a transaction number is key-input by the operation by the operator S from the clerk operation unit 108 (issue request), the CPU 101 converts the transaction data associated with the transaction number into a two-dimensional code. The CPU 101 issues a slip on which the two-dimensional code is printed from the printing unit 111 based on the confirmed transaction data. Thereby, even when a communication trouble occurs after printing the barcode on the slip, the CPU 101 can issue a slip on which the two-dimensional code is printed.

  Further, the CPU 101 displays the product name, subtotal price, etc. of the purchased product in the store clerk display unit 105 based on the product data read by the scanner unit 104 and the product data file (data table) stored in the hard disk 107. Display.

  The salesclerk display unit 105 is, for example, a liquid crystal display device, and displays information to the operator S. Here, the information displayed by the clerk display unit 105 is, for example, the product name of the purchased product, the number of purchases, the selling price, the deposit amount (custody amount), and the like.

  The customer display unit 106 is, for example, a liquid crystal display device, and presents information to the customer C. For example, the customer display unit 106 displays the same information as the information displayed by the store clerk display unit 105.

  The hard disk 107 stores the product data file supplied from the store controller 30 connected via the communication unit 109. The hard disk 107 is, for example, a magnetic recording device. The hard disk 107 may store a product registration program.

  The salesclerk operation unit 108 includes a numeric key for designating and inputting an amount of money, a current total key for designating and inputting that registration of all products purchased by the customer has been completed, and a request for issuing a slip (issue request) ) To the CPU 101.

  Further, the store clerk operation unit 108 may include a product designation key set in advance for inputting product data of a specific product. As a result, for a specific product, instead of the operation of reading the product data attached to the product, the product data of the specific product is added to the transaction data by pressing the product designation key corresponding to the product. Register.

  The communication unit 109 is a communication interface for communicating with an external device via the LAN 40 (see FIG. 2). The communication unit 109 transmits a transaction number and transaction data to the store controller 30.

  The buzzer 110 is a sound generator for generating a confirmation sound and a warning sound. The buzzer 110 generates a sound, for example, when the scanner unit 104 normally reads a barcode, when each key of the store clerk operation unit 108 is pressed, or when an incorrect operation is performed. .

  The printing unit 111 prints the barcode or two-dimensional code generated by the CPU 101 on a paper medium and discharges it.

Next, the settlement apparatus will be described.
The checkout device 20 reads a bar code or a two-dimensional code printed on the slip, and executes price checkout.

  FIG. 6 is a block diagram showing the configuration of the settlement apparatus. The settlement apparatus 20 includes a CPU 201, a ROM 202, a RAM 203, a scanner unit 204, a display unit 205, a customer operation unit 206, a communication unit 207, a buzzer 208, a printing unit 209, a change machine 210, And a bus 211. These are connected to each other via a bus 211.

  The ROM 202 stores an accounting program to be executed by the CPU 101. The ROM 202 stores a device number for identifying the device itself.

  The scanner unit 204 (slip reading unit) optically reads the barcode printed on the slip by the operation of the customer C, and outputs the transaction number represented by the read barcode to the CPU 201. The scanner unit 204 optically reads the two-dimensional code printed on the slip by the operation of the customer C, outputs the transaction data represented by the read two-dimensional code to the CPU 201, and the CPU 201 temporarily stores it in the RAM 203.

  The RAM 203 stores the product data file supplied from the store controller 30 via the communication unit 207. In addition, the transaction program read from the ROM 202 is expanded in the RAM 203. The RAM 203 temporarily stores various variables and data (for example, change amount) generated by executing the accounting program. The RAM 203 stores transaction data received by the communication unit 207. The RAM 203 stores transaction data represented by the two-dimensional code read by the scanner unit 204.

  The CPU 201 reads the accounting program stored in the ROM 202, expands it in the RAM 203, and executes the expanded accounting program steps to control the entire settlement apparatus 20.

  The CPU 201 (reading determination unit) determines whether the code read by the scanner unit 204 is a two-dimensional code. Here, whether or not the code is a two-dimensional code is determined based on, for example, whether or not the recording method (form) of the code is two-dimensional.

  When the code read by the scanner unit 204 is not a two-dimensional code, that is, when the code read by the scanner unit 204 is a bar code, the CPU 201 (control unit) executes price settlement based on the bar code. Specifically, the CPU 201 inversely converts the barcode into a transaction number, and outputs the transaction number acquired by the inverse conversion to the communication unit 207. Thereby, the transaction number acquired by the reverse conversion is transmitted to the store controller 30 via the communication unit 207. In addition, the CPU 201 acquires transaction data received by the communication unit 207 from the store controller 30.

  On the other hand, when the code read by the scanner unit 204 is a two-dimensional code, the CPU 201 executes payment adjustment based on the two-dimensional code. Specifically, the CPU 201 obtains transaction data directly from the two-dimensional code by inversely converting the two-dimensional code into transaction data, and executes payment settlement based on the directly obtained transaction data.

  The CPU 201 causes the display unit 205 to display information (hereinafter referred to as “accounting menu”) including a character string and the like for prompting the customer C to proceed with the payment. Further, the CPU 201 causes the display unit 205 to display the product name, the number of purchases, the sales price, and the total price of the purchased product based on the acquired transaction data. Further, the CPU 201 acquires the amount of cash (hereinafter referred to as “deposit amount”) that has been inserted into the change machine 210 from the change machine 210, and causes the display unit 205 to display the amount of payment. In addition, the CPU 201 causes the display unit 205 to display the change amount.

  If the deposit amount is equal to or greater than the total amount (see FIG. 4), the CPU 201 ends the payment settlement. Here, when the deposit amount is larger than the total amount, the CPU 201 discharges the cash equivalent to the change amount from the change machine 210. Further, the CPU 201 determines that the payment has been completed, and issues the receipt by discharging the receipt from the printing unit 209.

  The display unit 205 is a liquid crystal display device, for example, and displays information to the customer C. Here, the information displayed by the display unit 205 includes, for example, the product name of the purchased product, the number of purchases, the sales price, the deposit amount, the total amount, the change amount, and the accounting menu.

  The customer operation unit 206 is a touch panel type input device. The customer operation unit 206 outputs an operation signal to the CPU 201 in response to an operation on a GUI (Graphical User Interface) operation button displayed on the display unit 205. Here, as the GUI operation buttons, for example, an accounting key for causing the CPU 201 to start payment adjustment and a settlement key for causing the change machine 210 to start change processing are displayed on the display unit 205.

  The communication unit 207 is a communication interface for communicating with an external device via the LAN 40 (see FIG. 2). The communication unit 207 causes the RAM 203 to store the product data file supplied from the store controller 30 (see FIG. 2).

  In addition, when the CPU 201 determines that the code read by the scanner unit 204 is not a two-dimensional code, that is, the code read by the scanner unit 204 is a barcode, the communication unit 207 stores the transaction number represented by the barcode. It transmits to the controller 30 (refer FIG. 2). Further, the communication unit 207 receives the transaction data transmitted from the store controller 30 as the reply, outputs the received transaction data to the CPU 201, and the CPU 201 temporarily stores it in the RAM 203.

  The buzzer 208 is a sound generator for generating a confirmation sound and a warning sound. The buzzer 208 generates a sound, for example, when the scanner unit 204 normally reads a barcode, when each key of the customer operation unit 206 is pressed, or when an incorrect operation is performed. .

  When notified from the CPU 201 that the payment has been completed, the printing unit 209 prints the receipt on a paper medium and discharges it based on the transaction data stored in the RAM 203.

  FIG. 7 shows an example of a receipt. The receipt is printed with the name of the person in charge, the transaction date and time, the transaction number, the product name, the number of purchases of the product, the amount, the total amount, the deposit amount, and the store name. The product name and price for each product are detailed data.

  Returning to FIG. 6, the description of the settlement apparatus will be continued. The change machine 210 is provided with a cash inlet and outlet. The change machine 210 counts the cash (at least one of coins and bills) inserted into the insertion slot by the customer C, and notifies the CPU 201 of the amount of money. Moreover, the change machine 210 discharges | emits the amount of cash equivalent to the change amount from a discharge port based on the change amount notified from CPU201.

Next, the operation procedure of the POS system will be described.
FIG. 8 is a flowchart showing the operation procedure of the product registration apparatus. The CPU 101 (see FIG. 3) determines whether or not an operation required to issue a slip on which a two-dimensional code is printed is performed (step S1).

  When it is not required to issue a slip (step S1-NO), the CPU 101 executes product registration by inputting a product code. That is, the CPU 101 writes the contents in the item of transaction data stored in the processing area of the RAM 103 (step S2).

  The CPU 101 determines whether or not the product registration has been completed for all products purchased by the customer C. For example, when the current key is pressed, the CPU 101 determines that the product registration has been completed for all products purchased by the customer C (step S3). When the product registration has not ended (step S3-NO), the CPU 101 returns the process to step S2.

  On the other hand, when product registration is completed for all products (step S3-YES), the CPU 101 additionally stores the confirmed transaction data (see FIG. 4) in the log file of the RAM 103 (step S4). Then, the CPU 101 associates the confirmed transaction data with the transaction number, and transmits the transaction data to the log file of the store controller 30 by transmitting it to the store controller 30 via the communication unit 109 (step S5). ).

  Further, the CPU 101 determines whether or not the communication state is good depending on whether or not the transmission is normally performed in step S5 (step S6). If the CPU 101 determines that the communication state is good (step S6-YES), it converts the transaction number into a barcode and causes the printing unit 111 to issue a slip printed with the barcode representing the transaction number (step S7). . Then, the CPU 101 returns the process to step S1.

  On the other hand, if the CPU 101 determines that the communication state is negative, that is, the communication state is not good (step S6-NO), the confirmed transaction data stored in the RAM 103 is converted into a two-dimensional code, and the transaction is performed. A slip on which a two-dimensional code representing data is printed is issued from the printing unit 111 (step S8). Then, the CPU 101 returns the process to step S1.

  Further, when the scanner unit 104 scans the barcode printed on the slip in step S1, or when the transaction number is key-input from the store clerk operation unit 108 (step S1-YES), the CPU 101 corresponds. A slip printed with the two-dimensional code obtained by converting the transaction data is issued (step S9). Then, the CPU 101 returns the process to step S1.

  FIG. 9 is a flowchart showing the operation procedure of the settlement apparatus. The CPU 201 (see FIG. 6) determines whether or not the code read by the scanner unit 204 is a two-dimensional code (step Sa1). In step Sa1, if the code read by the scanner unit 204 is a two-dimensional code (step Sa1-YES), the CPU 201 shifts the processing to step Sa4. On the other hand, if the code read by the scanner unit 204 is not a two-dimensional code (step Sa1-NO), the CPU 201 reversely converts the barcode read by the scanner unit 204 into a transaction number, and the transaction number obtained by the reverse conversion is The data is transmitted to the store controller 30 via the communication unit 207 (step Sa2).

  Further, the CPU 201 determines whether or not the communication unit 207 has received transaction data from the store controller 30 within a predetermined time (step Sa3). When the transaction data is received within the predetermined time, the CPU 201 displays the total amount on the display unit 205 (step Sa4).

  In addition, the CPU 201 executes price processing. Here, the CPU 201 causes the display unit 205 to display an accounting menu. Further, the CPU 201 causes the display unit 205 to display the product name, the number of purchases, the sales price, and the total price of the purchased product based on the acquired transaction data. In addition, the CPU 201 acquires the deposit amount from the change machine 210 and causes the display unit 205 to display the deposit amount. In addition, the CPU 201 causes the display unit 205 to display the change amount. If the deposit amount is equal to or greater than the total amount (see FIG. 4), the CPU 201 ends the payment settlement. When the deposit amount is larger than the total amount, the CPU 201 discharges the cash equivalent to the change amount from the change machine 210 (step Sa5).

  Further, the CPU 201 issues a receipt by discharging the paper medium on which the receipt is printed from the printing unit 209 when the payment is completed (step Sa6). Then, the process returns to step S1.

If the transaction data is not received within the predetermined time in step Sa3 (step Sa3-NO), the CPU 101 determines that a message (for example, “transaction data cannot be obtained from this slip printed with a barcode by communication. “Please let the same registration device scan the barcode printed on this voucher and issue the voucher printed with QR code (registered trademark)” on the display unit 205 (Step Sa7).
Then, the process returns to step Sa1.

  FIG. 10 is a flowchart showing the operation procedure of the store controller. A store controller communication unit (not shown) of the store controller 30 determines whether or not transaction data has been received (step Sb1). When the transaction data is received (step Sb1-YES), the store controller communication unit stores the received transaction data in a log file of a store controller storage unit (not shown) of the store controller 30 (step Sb2). Then, the store controller communication unit returns the process to step Sb1.

  In step Sb1, when transaction data is not received (step Sb1-NO), the store controller communication unit determines whether a transaction number has been received (step Sb3). When the transaction number is received (step Sb1-YES), the store controller communication unit searches the transaction data associated with the received transaction number from the log file stored in the store controller storage unit (step Sb4). . Based on the search result, the store controller communication unit returns the transaction data associated with the received transaction number to the settlement apparatus 20 that transmitted the transaction number (step Sb5). Then, the store controller communication unit returns the process to step Sb1.

  In step Sb3, when the transaction number is not received (step Sb1-NO), the store controller communication unit executes other processing (for example, management and maintenance of the product data file). Then, the store controller communication unit returns the process to step Sb1 (step Sb6).

  As described above, a product registration device that performs product registration by reading the product data attached to the product purchased by the customer and finalizes transaction data including the details of the product, and details based on the confirmed transaction data In a POS system having a settlement apparatus that executes payment settlement accompanied by issuance of a receipt printed with POS, the POS system 100 stores a transaction number associated with the transaction data and the transaction data. A store controller communication unit that receives the transaction number, acquires transaction data associated with the received transaction number from the store controller storage unit, and returns the acquired transaction data. The CPU 101 stores the transaction data and the transaction number in the storage unit of the product registration device 10 in association with each other, CPU 101 for determining whether the state of the roller communication unit is good, and when CPU 101 determines that the state is good, the transaction number is converted into a barcode, a slip printed with the barcode is issued, and the communication state The CPU 101 determines that the transaction data is converted to a two-dimensional code and issues a slip printed with the two-dimensional code, and the checkout device 20 is printed on the slip When the scanner unit 204 that can read a barcode and a two-dimensional code, the CPU 201 that determines whether or not the code read by the scanner unit 204 is a two-dimensional code, and the CPU 101 that is not a two-dimensional code The transaction number represented by the barcode is transmitted to the store controller communication unit, and the transaction data associated with the transmitted transaction number is stored. When the CPU 201 determines that the communication unit 207 receives the two-dimensional code from the communication unit 207 received from the controller communication unit, the communication unit 207 executes the payment adjustment based on the two-dimensional code and determines that the barcode is read. CPU201 which performs price settlement based on the transaction data which received.

As a result, the POS system reads the two-dimensional code representing the transaction data from the slip when a communication trouble occurs between the apparatuses, so that even when a communication trouble occurs between the apparatuses, the payment can be performed.
Further, when a communication trouble occurs between the devices, the POS system quickly switches between price settlement using the barcode and price settlement using the two-dimensional code according to the communication state between the devices. For this reason, even if a communication trouble occurs between devices, the customer is not confused.
In addition, the operation performed by the customer does not change between the price settlement using the barcode and the price settlement using the two-dimensional code. For this reason, even if a communication trouble occurs between devices, the customer is not confused.

In addition, the code printed on the slip when no communication trouble occurs between the devices is a bar code, while the code printed on the slip when a communication trouble occurs between the devices is a two-dimensional code. .
As a result, the price settlement using the two-dimensional code that takes a longer time to read than when reading the bar code is executed only when a communication trouble occurs between the apparatuses. For this reason, the POS system can promptly perform payment settlement as a whole.

The POS system 100 also allows the merchandise registration apparatus 10 to store the corresponding transaction data even after issuing a slip printed with a barcode, and to issue a slip printed with a two-dimensional code.
Thereby, the POS system can issue a slip printed with the second code even in a transaction in which a communication trouble occurs after printing the first code on the slip.

  The embodiment of the present invention has been described in detail with reference to the drawings. However, the specific configuration is not limited to this embodiment, and includes designs and the like that do not depart from the gist of the present invention.

  For example, for each transaction data in the log file, a flag transmitted to the settlement apparatus and a flag for which the settlement apparatus has finished accounting are provided, and each time the settlement apparatus processes, the process is transmitted to the store controller and the product registration apparatus. You may do it.

For example, the code representing the transaction number may not be limited to a barcode. The code representing the transaction number is a code system (standard) whose maximum data amount is limited to a small size, that is, having a small capacity and capable of high-speed reading, and is machined by an optical reader (OCR: Optical Character Reader) or the like. Any barcode that can be read is not limited to a barcode.
Further, the code representing transaction data need not be a two-dimensional code. A code representing transaction data is limited to a two-dimensional code as long as the maximum data amount is not limited to a small size, that is, a code system having a large capacity and can be machine-readable by an optical reader or the like. I can't.
Further, the difference for identifying the code representing the transaction number and the code representing the transaction data is not limited to whether or not the recording method (form) of the code is two-dimensional. For example, the code representing the transaction number and the code representing the transaction data may be identified according to a difference in the code system whether or not the maximum data amount is limited by the system (standard). .

Further, for example, the means for storing transaction data and the means for transmitting are not limited to being provided in the store controller 30, but these means are provided in the merchandise registration apparatus, and the settlement apparatus corresponds to the merchandise registration apparatus corresponding to the transaction number of the slip. A request may be made and received.
Further, for example, the settlement apparatus may be operated by a store clerk rather than operated by a customer (not self-service).

Further, for example, the payment apparatus may include a credit card terminal, an electronic money terminal, and the like.
Thereby, the payment apparatus can perform payment adjustment other than cash.
