The ROM 202 is a read-only memory, and stores various information used by the CPU 201 including programs.

A RAM 203 is a read/write memory and stores various information. For example, the RAM 203 stores information acquired from the outside (for example, product master information acquired from the store controller 10) and information generated during processing (for example, registration information generated during registration processing, settlement information generated during settlement processing, etc.). memorize In the following description, one or both of registration information and settlement information may be referred to as transaction information.

The hard disk 204 stores various information. The hard disk 204 may store programs executed by the CPU 201 instead of the ROM 202, for example. Also, instead of the RAM 203, information obtained from the outside or information generated during processing may be stored.
A storage device such as an SSD (Solid State Drive) may be provided instead of the hard disk 204 .

The customer-side display unit 205 is a touch display for customers, which displays various information to the customer and receives various inputs from the customer.
A customer-side scanner unit 206 is a scanner unit for customers, and optically reads, for example, a bar code (such as a product code) attached to a product.

The customer-side scanner unit 206 is used when the customer registers the product, but the customer may register the product by another method. For example, when an item order button or the like is displayed on the customer-side display unit 205, the customer can operate (press) the order button to register the item.

The card reader 208 can read information from various cards (credit cards, transportation cards, etc.) and execute processing corresponding to settlement. Also, the card reader 208 can read information such as membership cards and point cards. The card reader 208 of this embodiment may include, for example, a card recognition unit (reading unit), a display unit, and an operation unit, and may include at least a card recognition unit.

The change dispenser 209 (cash settlement unit) is a settlement mechanism using cash, and has an insertion port for banknotes and coins and a discharge port for banknotes and coins. The amount of change, which is the difference, is calculated, and the change is discharged from the discharge port.

The key operation unit 211 is composed of various keys (buttons) and receives various inputs from the store clerk.
The clerk-side scanner unit 212 is a scanner unit for a clerk, and optically reads, for example, a bar code (product code, etc.) attached to a product or a clerk code attached to a clerk's name tag.

Note that the clerk-side scanner unit 212 is used when the clerk registers products, but the clerk may register the products by other methods. For example, if a key corresponding to a product (for example, a key corresponding to a sports newspaper) is arranged in the key operation unit 211, the store clerk can operate (press) the key to register the product. can. Also, when a preset key corresponding to a product is displayed on the clerk-side display unit 210, the clerk can operate the preset key to register the product.

The printing unit 213 is a printing unit that ejects media, and prints and issues various media such as receipts. The printing unit 213 is a single printing unit that can be rotatably changed from the clerk side to the customer side and from the customer side to the clerk side (the direction of the medium issuing port). The orientation of the printing unit 213 may be changed manually, or may be changed automatically (mechanically controlled, etc.) according to the transition of the operation mode, for example. Note that whether the orientation of the printing unit 213 is correct or incorrect may be detected by a sensor or the like.

The imaging unit 216 is provided so as to capture an image of a customer performing an operation related to checkout at the customer's standing position. A captured image obtained by capturing an image by the imaging unit 216 can be used as a monitoring image for monitoring a customer who pays the bill. In addition, the POS terminal 20 can store the image captured by the imaging unit 216 in a storage device such as the hard disk 204 or the like.

The sign pole 217 is a part that lights up in a predetermined pattern and color to give a predetermined notification to the store clerk.

[Outline of each operation mode]
Next, operation modes of the POS terminal 20 will be described. The POS terminal 20 has multiple operating modes. Specifically, the POS terminal 20 has four types of operation modes (normal mode, full self mode, double scan mode, semi self mode). The operation modes described below are the operation modes related to accounting during normal business (operation modes related to product registration processing and settlement processing). It does not include the maintenance mode for setting work or maintenance work by staff members, or the training mode for training newcomers.
In this embodiment, "accounting" is a concept that includes, for example, product registration in one transaction and settlement (settlement) of the registered product.
In the following description, the mode in which the POS terminal 20 executes product registration processing is referred to as a registration mode, and the mode in which payment processing is performed is referred to as a payment mode, as a different approach from the four operation modes described above. There is

[Normal mode]
The normal mode is an operation mode in which the store clerk executes the registration process and the customer executes the settlement process. That is, in the case of the normal mode, the store clerk side becomes the registration mode, and the customer side becomes the checkout mode. In other words, the POS terminal 20 operates in the registration/settlement mode when viewed from the registration process to the settlement process as a whole.

In the normal mode, the clerk registers the purchased product of the customer on the clerk side (clerk side scanner section 212, clerk side display section 210, key operation section 211). In other words, the POS terminal 20 executes registration processing of the purchased product by the operation of the store clerk (operation of the store clerk side scanner unit 212, store clerk side display unit 210, key operation unit 211, etc.).

When the store clerk completes the registration process, the customer confirms the total amount of purchased commodities on the store clerk side display unit 210 and inserts money into the change machine 209 or operates the card reader 208 to settle the bill. In other words, the POS terminal 20 executes settlement processing according to a customer's operation (insertion of money into the change machine 209, operation of the card reader 208).

The customer may wait until the store clerk completes the registration process (until the total amount is determined), but may insert money into the change machine 209 before the registration process is completed. In other words, the POS terminal 20 can accept payment during the registration process.

In addition, the clerk may wait until the customer completes the payment (until the customer obtains the change or the receipt), or may register the next customer's purchased product. In other words, the POS terminal 20 can register the next customer's purchased product during the checkout process. Also, the clerk may be absent while the customer is checking out. In other words, the reception of the customer may be finished during the payment of the customer.

In addition, when there is change, the POS terminal 20 controls the dispensation of change or bills by the change machine 209 in order to prevent forgetting to take the change, and a sensor or the like detects that the customer has removed the change or bills. , the printing unit 213 is controlled to issue a receipt. The same applies to other operation modes. As described above, in the normal mode (the same applies to the double scan mode), there may or may not be a store clerk in front of the customer who receives the change. (That is, the payment of change/change and the receipt may be issued at the same time, or the receipt may be issued first). Further, the timing of paying out change/tills and issuing receipts may be controlled according to the current operation mode and the presence/absence of a clerk (for example, the presence/absence of a clerk is recognized by a sensor).

[Full self mode]
The full-self mode is an operation mode in which the customer executes registration processing and the customer executes settlement processing. That is, in the case of the full self mode, the customer side becomes both the registration mode and the payment mode. In other words, the POS terminal 20 operates in the registration/settlement mode when viewed from the registration process to the settlement process as a whole.

In the case of the full self mode, the customer registers the purchased product on the customer side (customer side scanner section 206, customer side display section 205). In other words, the POS terminal 20 executes registration processing of the purchased product by the customer's operation (scanning by the customer-side scanner unit 206, touching the customer-side display unit 205).

When the registration process is completed, the customer confirms the total amount of purchased products on the customer-side display unit 205, inserts money into the change machine 209, or operates the card reader 208 in the case of credit card payment, and settles the account. do. In other words, the POS terminal 20 executes settlement processing according to a customer's operation (insertion of money into the change machine 209, operation of the card reader 208).

In the full-self mode, as described above, the customer side executes both the registration process and the settlement process, but this does not mean that the store clerk cannot do anything. That is, even when the POS terminal 20 is operating in the full self mode, the clerk-side scanner unit 212 can scan the clerk code. In addition, the POS terminal 20 can display various information on the clerk-side display section 210 even when operating in the full self mode.
For example, during operation in the full-self mode, a screen similar to that displayed on the customer-side display unit 205 can be displayed on the salesclerk-side display unit 210 in accordance with the registration processing and settlement processing performed on the customer side. may be displayed. In other words, the contents displayed on the customer-side display unit 205 may be mirrored on the salesclerk-side display unit 210 . This allows the clerk to grasp what kind of operation the customer is performing and what kind of processing status the POS terminal 20 is in in the full-self mode.

[Double scan mode]
The double scan mode is an operation mode in which registration processing is executed on both the store clerk side and the customer side, and settlement processing is executed on the customer side. That is, in the case of the double scan mode, both the clerk side and the customer side are in the registration mode, and the customer side is in the checkout mode. In other words, the POS terminal 20 operates in the registration/settlement mode when viewed from the registration process to the settlement process as a whole.

In the case of the double scan mode, the clerk registers the purchased product on the clerk side (clerk side scanner unit 212, clerk side display unit 210, key operation unit 211), and the customer registers the purchased product on the customer side (customer side scanner unit 211). 206, customer-side display unit 205). That is, the POS terminal 20 can be operated by a clerk (scanning by the clerk-side scanner unit 212, touching the clerk-side display unit 210, pressing the key operation unit 211, etc.) and by a customer (customer-side scanner unit 206). , and touch on the customer-side display unit 205), registration processing of the purchased product is executed.

When the registration process is completed, the customer confirms the total amount of purchased products on the customer-side display unit 205, inserts money into the change machine 209, or operates the card reader 208 in the case of credit card payment, and settles the account. do. In other words, the POS terminal 20 executes settlement processing according to a customer's operation (insertion of money into the change machine 209, operation of the card reader 208).

The store clerk may wait until the customer completes the payment (until the customer obtains change or a receipt), or may register the next customer's purchased product. In other words, the POS terminal 20 can register the next customer's purchased product during the checkout process. Also, the clerk may be absent while the customer is checking out. In other words, the reception of the customer may be finished during the payment of the customer.

[Semi-self mode]
The semi-self mode is an operation mode in which two or more POS terminals 20 are used, in which registration processing is executed by the clerk of at least one POS terminal 20, and payment is made by the customer of the other POS terminal 20. This is the operation mode for executing processing. That is, in the semi-self mode, one or more POS terminals 20 are in the registration-only mode, and one or more other POS terminals 20 are in the payment-only mode.

In the semi-self mode, the clerk registers the purchased product of the customer at the POS terminal 20 in the registration-only mode on the clerk side (clerk side scanner section 212, clerk side display section 210, key operation section 211). In other words, the POS terminal 20 executes registration processing of the purchased product by the operation of the store clerk (operation of the store clerk side scanner unit 212, store clerk side display unit 210, key operation unit 211, etc.).

When the registration process by the clerk is completed, the customer moves to the POS terminal 20 in the settlement-only mode, confirms the total amount of purchased commodities on the clerk-side display unit 210, inserts money into the change machine 209, or presses the card reader. 208 and settle the account. In other words, the POS terminal 20 executes settlement processing according to a customer's operation (insertion of money into the change machine 209, operation of the card reader 208).

When the registration process is completed at the POS terminal 20 in the registration-only mode, the customer moves from the POS terminal 20 in the registration-only mode to the POS terminal 20 in the settlement-only mode. Necessary information (such as registration information generated by the POS terminal 20 in registration-only mode) is supplied.

Note that the destination POS terminal 20 (of the POS terminals 20 in the settlement-only mode, the POS terminal 20 that executes the settlement process) may be specified in the POS terminal 20 in the registration-only mode. Alternatively, the POS terminal 20 in the registration-only mode issues a medium (a medium on which a bar code or the like for obtaining information necessary for settlement processing is printed), and the POS terminal 20 in the settlement-only mode that reads the medium is used. It may be the POS terminal 20 at the destination.

In the semi-self mode, after sending the registration information, the store clerk can register the next customer's purchased product. Also, the store clerk may be absent after sending the registration information.

[Continuous registration confirmation screen display]
In the case of the POS terminal 20 in which the full-self mode is set, the customer himself/herself performs operations according to the checkout from product registration to payment.
When the customer pays by the POS terminal 20 in the full self mode, the customer performs an operation to read the merchandise code for each merchandise he or she intends to purchase at the stage of merchandise registration.

When the customer had the product code read at the time of product registration as described above, the customer intended to have the product code of one product read by one operation, but the customer side of the POS terminal 20 The scanner unit 206 may read the same product code twice or more consecutively.

One of the operations of the POS terminal 20 when the result is that the same product code has been read a plurality of times in succession is to read the next product code without notifying the customer. It can also be made to accept reads. In this case, although the flow of product registration is not interrupted, the customer may not be aware of it. If the customer completes the payment without noticing, the customer will end up paying more than the price corresponding to the product that the customer intends to purchase.

As another operation of the POS terminal 20 when the result is that the same product code has been read continuously a plurality of times, for example, a dialog window is displayed to notify the customer that the same product code has been read continuously. is displayed, and depending on the operation performed on the dialog window, product registration corresponding to the product code read from the second time onward may be performed or not performed. However, in this case, a customer who is going to purchase multiple items of the same product may make a mistake in the operation, etc., even though product registration corresponding to the product code read from the second time onwards has not been performed. There is a possibility that you may proceed with the checkout by mistakenly thinking that the product has been registered.

Therefore, the POS terminal 20 of the present embodiment displays a continuous registration confirmation screen as described below in response to the result that the same product code has been read a plurality of times in succession. be. This prevents customers from completing the checkout without noticing it, and customers who misunderstand that an unregistered product has been registered and proceed to checkout. do.

FIG. 5 shows an example of a product registration screen displayed on the customer-side display section 205 of the POS terminal 20 in full self mode. In the product registration screen of FIG. 1, a registration guide area AR11, a registered product area AR12, and a checkout transition instruction button BT12 are arranged.

The registration guidance area AR11 is an area where guidance for customers regarding product registration is provided. In the registration guidance area AR11, the customer is instructed to read the bar code attached to the product to be registered (for example, it may be another code such as a two-dimensional code) with the customer-side scanner unit 206. A message, image, or the like is displayed to guide the user to perform the product registration operation.

In addition, in the registration guide area AR11 in the same figure, when the product to be registered does not have a barcode attached, a screen (item designation registration screen) for specifying and registering the item of the product to be registered is displayed. An item designation registration instruction button BT11 for displaying is arranged.
An item designation registration screen is displayed in response to the operation of the item designation registration instruction button BT11, and the customer selects the item of the merchandise to be registered from among the items of the merchandise displayed on the displayed item designation registration screen. Product registration can be performed by performing the designated operation.

The registered product area AR12 is an area in which information on products that have been registered so far is presented. In the registered product area AR12 in the figure, list items for each registered product, the number of registered products (registration points (purchase points)), and the total price of the registered products are displayed.
In the registered product area AR12 in this case, it is shown that one "mineral water" is registered. That is, in the registered product area AR12, one list item corresponding to one "mineral water" is arranged, the registered score indicates "1 point", and the total amount is "98 Yen" corresponding to ".

In addition, a surveillance captured image IM is arranged at the lower left end of the product registration screen in FIG. The captured monitoring image IM displays a captured image captured by the imaging unit 216 corresponding to the current time. By displaying the surveillance captured image IM in this way, the customer becomes aware that he or she is being monitored by imaging while paying. In this way, fraud by customers can be prevented.

In the state where one "mineral water" is registered as shown in the figure, the customer registers another "mineral water" of the same item as the next product. In other words, the customer has performed an operation to have the customer-side scanner unit 206 read the product code of the same item "mineral water" twice in succession, the previous registration and the current registration.

In this case, the POS terminal 20 has read the same product code twice consecutively. As a result, the POS terminal 20 has sequentially registered two identical products corresponding to the two identical product codes read in sequence.

If the same product code is read twice in succession in this way, it will be one of the following two cases. One is the case where the customer intentionally causes the product codes of the same two products to be read in order, as in the example described here. The other is a case where the customer intends to read the product code of one product, but the customer-side scanner unit 206 reads the product code of the product twice consecutively. is.
When the same product code is read twice in succession in this manner, the POS terminal 20 displays a continuous registration confirmation screen.
Even when the POS terminal 20 reads the product code of one product consecutively twice, the POS terminal 20 sequentially registers the same two products according to the two product codes read in sequence.

The product registration can be performed not only by reading the product code with the customer-side scanner unit 206, but also by specifying the product on the product specification registration screen displayed by operating the product specification registration instruction button BT11. The continuous registration confirmation screen is displayed in response to the case where the customer side scanner unit 206 reads the same product code twice in succession and the same product is registered twice in succession. If the same product is registered twice in succession, including product registration by operating the item designation registration screen, the continuous registration confirmation screen may not be displayed.

FIG. 6 shows an example of a continuous registration confirmation screen WD30. The continuous registration confirmation screen WD30 in the figure is displayed as a dialog window superimposed on the product registration screen.
On the continuous registration confirmation screen WD30 in the same figure, there is a message MS that informs the customer that the same two products have been registered consecutively (that is, the same product code has been read twice consecutively). is displayed. A confirmation button BT30 is arranged on the continuous registration confirmation screen WD30.

Also, in this case, following the first registration of "mineral water", the second "mineral water" was registered in response to the reading of the product code of the product as "mineral water" for the second time. . Therefore, the product registration screen displayed in the background of the continuous registration confirmation screen WD30 in FIG. 6 has changed from the state in FIG. 5 to a state in which the second registration of "mineral water" is reflected.
Specifically, regarding the arrangement of the list items in the registered product area AR12 of the product registration screen, in FIG. The two list items corresponding to each are updated to be arranged. Also, the number of purchased items hidden by the continuous registration confirmation screen WD30 in the registered merchandise area AR12 has been updated from 1 point in FIG. 5 to 2 points. Also, the total amount in the registered product area AR12 is updated from 98 yen in FIG. 5 to 196 yen.

By displaying the continuous registration confirmation screen WD30, the customer can understand that the same product has been registered twice in succession.
In this case, as in this case, if the customer intends to purchase the same two products and performs the operation to have the product code of the same product read twice in a row, the customer It can be judged that there is no problem with the state in which the same product is registered twice in succession. The customer can also understand that the second product ("mineral water") has already been registered by looking at the registered product area AR12 of the product registration screen displayed together with the continuous registration confirmation screen WD30.
On the other hand, if the continuous registration confirmation screen WD30 is displayed even though the customer has not read the product codes of the same two products in succession, the customer will be asked to read the product codes of the current product. In addition, it can be determined that the POS terminal 20 has mistakenly read the product code twice. After that, by looking at the registered product area AR12 of the product registration screen displayed together with the continuous registration confirmation screen WD30, the customer reads the current product code because the product code has been read twice. According to the operation, it can be known that two products have also been registered.
Note that the list items corresponding to the second registration of "mineral water" may be displayed in a manner different from the list items corresponding to the first registration of "mineral water". This makes it easier for the customer to confirm that the same product has been registered twice consecutively.

In addition, the sorting order of the list items in the registered product area AR12 may be reversed from the example shown in FIG. In this case, the list item of the product registered last among the products registered so far is arranged in the top row of the registered product area AR12.

Registration of new products is prohibited while the continuous registration confirmation screen WD30 is displayed. Therefore, even if the customer performs an operation to cause the customer-side scanner unit 206 to read the product code while the continuous registration confirmation screen WD30 is being displayed, the product is not registered.
When the customer causes the customer-side scanner unit 206 to read the product code while the continuous registration confirmation screen WD30 is being displayed, the POS terminal 20 warns the customer that product registration is not possible. Notification (warning notification) may be performed. Such a warning notification that product registration is impossible may be performed by outputting a sound such as a warning sound or voice, for example. With such warning notification, the customer can understand that the product registration is not performed even if the product code is read. Note that the warning that product registration is not possible may be displayed on the customer-side display unit 205 in a predetermined manner.

In this case, the customer either causes the product codes of the same two products to be read in order or the product code of one product is read by the customer-side scanner unit 206 twice consecutively. Even if there is, the confirmation button BT30 is operated.
In response to the confirmation button BT30 being operated, the continuous registration confirmation screen WD30 is erased, and the product registration screen, which was the background in FIG. 6, is displayed in the foreground. As the continuous registration confirmation screen WD30 is erased, product registration, which has been prohibited up to now, is permitted, and new product registration can be performed by causing the customer-side scanner unit 206 to read the product code of the product. Become.
When the customer has read the product codes of the same two products in order, the customer can resume the product registration operation (the operation of causing the customer-side scanner unit 206 to read the product codes of the products).

On the other hand, if the customer-side scanner unit 206 has read the product code of one product twice in succession, one of the products registered twice in succession is deleted from the registration. registration details. In this case, the customer calls a store clerk and asks the store clerk who comes to the POS terminal 20 in response to the call to change the product registration contents. In this case, the clerk may operate the POS terminal 20 to correct the registration of the product from the product registration information showing the product registration results thus far, or the clerk may Alternatively, an operation may be performed to cancel the product registration information indicating the product registration results so far, and the product may be registered from the beginning (or the customer may register the product).

By displaying the continuous registration confirmation screen WD30 in this manner, the customer can notice when the customer-side scanner unit 206 reads the product code of one product twice in succession. . As a result, it is possible to prevent the customer from proceeding with the checkout without noticing that a certain product has been excessively registered and paying an unnecessary price.
Also, in this case, when the same product code is read twice in succession, the POS terminal 20 executes product registration without suspending product registration according to the product code read the second time. After that, the continuous registration confirmation screen WD30 is displayed. Therefore, when the customer has the product codes of the same two products read in order, the same two products read are already registered when the consecutive registration confirmation screen WD30 is displayed. . This prevents the customer from forgetting to register the second product and proceeding with the checkout.

[Example of processing procedure]
An example of a processing procedure executed by the POS terminal 20 in connection with product registration will be described with reference to the flowchart of FIG. The process of FIG. 10 starts from a state in which the POS terminal 20 displays a product registration screen on the customer-side display unit 205 and waits for product registration to be performed. In addition, in explaining the processing in the same figure, the operation of specifying the item of the product to be registered among the items of the product displayed on the item designation registration screen is not performed as the operation of registering the product. A case where an operation is performed to cause the 206 to read a product code will be taken as an example.

Step S100: The POS terminal 20 waits for product registration with the product registration screen displayed.
Step S102: When the customer-side scanner unit 206 reads the product code in response to the customer's operation to cause the customer-side scanner unit 206 to read the product code, the POS terminal 20 starts product registration processing. Execute. That is, the POS terminal 20 acquires the product information associated with the product code read by the customer-side scanner unit 206 from the product master stored in the store controller 10 . The POS terminal 20 includes the acquired product information in the product registration information for the current transaction.
Step S104: The POS terminal 20 updates the contents of the product registration screen so as to reflect the result of the product registration processing in step S102. By the processing of step S104, addition of list items of newly registered products, change of points purchased, change of total price, etc. are performed in the registered product area AR12 of the product registration screen.

Step S106: The POS terminal 20 refers to the product registration result of the current step S102 and the product registration result of the previous step S102, and confirms that the same product is registered twice in succession by the current product registration. It is determined whether or not. This determination also corresponds to determining whether or not the same product code has been read twice in succession.

Step S108: When it is determined in step S106 that the same product has been registered twice in succession, the POS terminal 20 causes the customer-side display unit 205 to superimpose it on the product registration screen. to start displaying the continuous registration confirmation screen WD30.

Step S110: The POS terminal 20 determines whether or not the product code has been read by the customer-side scanner unit 206 while the continuous registration confirmation screen WD30 is being displayed.
Step S112: If it is determined in step S110 that the product code has been read by the customer-side scanner unit 206, the POS terminal 20 does not execute product registration processing according to the read product code, and issues a warning notification. conduct. The warning information may be output by sound as described above, or may be by display.
As described above, the process of steps S110 and S112 prohibits the product registration process according to the reading of the product code while the continuous registration confirmation screen WD30 is being displayed.

Step S114: After the process of step S112, or when it is determined in step S110 that the product code has not been read, the POS terminal 20 determines whether or not the customer's confirmation operation has been performed. The confirmation operation in this case is performed assuming that the customer has confirmed that the same product has been registered twice in succession, as notified to the customer by the continuous registration confirmation screen WD30. Specifically, the confirmation operation is an operation on the confirmation button BT30 arranged on the continuous registration confirmation screen WD30.
If it is determined in step S114 that the confirmation operation has not been performed, the process returns to step S110.

Step S116: If it is determined in step S114 that the confirmation operation has been performed, the POS terminal 20 clears the continuous registration confirmation screen WD30 that has been displayed so far. Since the continuous registration confirmation screen WD30 is deleted, the product registration screen displayed in the background of the continuous registration confirmation screen WD30 is displayed in the foreground on the customer side display unit 205.例文帳に追加

Step S118: As described above, if the customer has read the product codes of the same two products in order, the continuous registration confirmation screen WD30 is deleted in step S116 and the product registration screen is displayed. Subsequent product registration operations can be resumed. Alternatively, when the continuous registration confirmation screen WD30 is erased and the product registration screen is displayed, if the product registration for all the products to be registered has been completed, the customer can proceed with subsequent payments. operation can be carried out.
On the other hand, if the customer intends to read the product code of one product, but the customer-side scanner unit 206 reads the product code twice in succession, the clerk will respond. to change the product registration details. The store clerk operates the POS terminal 20 to set the registration change mode in order to change the product registration content.
Therefore, the POS terminal 20 determines whether or not the registration change mode has been set after the continuous registration confirmation screen WD30 is cleared in step S116.

Step S120: When the registration change mode is set, the POS terminal 20 executes the registration change process according to the operation of the store clerk under the set registration change mode. The registration change process may be a process of correcting the product registration information so as to delete the registration of the corresponding product from the product registration information indicating the product registration result in one transaction so far. Alternatively, the registration change process may be a process of canceling product registration information in which product registration results are indicated in one previous transaction.
When the registration change processing in step S120 is completed, the registration change mode is terminated, and the mode returns to the checkout mode corresponding to product registration and payment.

Step S122: After the process of step S120, or when it is determined in step S118 that the registration change mode has not been set, the POS terminal 20 determines whether or not an instruction to shift to settlement has been performed. The settlement shift instruction operation is an operation performed on the settlement shift instruction button BT12 on the product registration screen.
If it is determined that the settlement transfer instruction operation is not performed, the process is returned to step S100.

Step S124: When it is determined in step S122 that the instruction operation to shift to settlement has been performed, the POS terminal 20 shifts to settlement processing.

Note that the consecutive registration confirmation screen WD30 may be erased when a certain period of time has elapsed since the display was started. In this case as well, the state in which product registration is prohibited may be switched to the state in which product registration is permitted in response to the fact that the continuous registration confirmation screen WD30 has been erased over time.

In the continuous registration confirmation screen WD30 in FIG. 6, one confirmation button BT30 is arranged as a button operated by the customer. Two buttons may be arranged.
Also in this case, the POS terminal 20 may register the same two products whose product codes are read in succession. After that, the POS terminal 20 may maintain the registration of the same two products in response to the operation of the "Yes" button. On the other hand, if the "No" button is operated, the POS terminal 20 may cancel the registration of one of the same two commodities registered in succession. At this time, the POS terminal 20 may cancel the registration of the later registered product among the same two products registered in succession.
Also, in this case, on the continuous registration confirmation screen WD30, to maintain the registration of the same two products, press the "Yes" button, and to cancel the registration of one of the same two products, It is preferable to display a message that guides the user to operate the "No" button.

According to the process of FIG. 10, when the continuous registration confirmation screen WD30 is displayed, the POS terminal 20 prohibits product registration processing in response to reading of a new product code.
As a modification of the present embodiment, the POS terminal 20 may be configured to be able to perform product registration processing in response to reading of a new product code even when the continuous registration confirmation screen WD30 is displayed.
For example, if the customer is accustomed to paying at the POS terminal 20 in full self-service, it is better to allow the customer to continue registering products even when the continuous registration confirmation screen WD30 is displayed. , you can proceed with product registration efficiently. In this case, the continuous registration confirmation screen WD30 may be cleared by operating the confirmation button BT30 at an arbitrary timing until the customer issues an instruction to shift to settlement.

<Second embodiment>
Next, a second embodiment will be described.
As shown in FIG. 6, the continuous registration confirmation screen WD30 of the first embodiment is arranged on the product registration screen at a position substantially centered in the vertical direction of the product registration screen due to its screen size smaller than that of the product registration screen. displayed as By displaying the continuous registration confirmation screen WD30 in such a manner, a certain or more area is secured in which the registered product area AR12 in the product registration screen is displayed without being hidden together with the continuous registration confirmation screen WD30. is made visible. This makes it easy for the customer to accurately grasp which of the products registered up to the current stage has been registered twice consecutively corresponding to the current consecutive registration confirmation screen WD30.

When displaying the continuous registration confirmation screen WD30, the POS terminal 20 of the present embodiment does not place it in the center of the product registration screen, but places it at a predetermined position to the left of the position shown in FIG. 6, for example. Set the position like Thus, after arranging the continuous registration confirmation screen WD30 on the product registration screen, the registered product area AR12 on the product registration screen is made more visible.
In this case, the POS terminal 20 sets both the position and the size of the continuous registration confirmation screen WD30 to be small so that the area where the registered product area AR12 is not hidden is increased, or the area where the registered product area AR12 is hidden is increased. should not occur.

Further, the POS terminal 20 may set a predetermined degree of transparency for the consecutive registration confirmation screen WD30 so that the area of the product registration screen in the layer below the consecutive registration confirmation screen WD30 can be seen through.
In this case, the POS terminal 20 may, for example, set the transparency of the continuous registration confirmation screen WD30 instead of setting the position and size of the continuous registration confirmation screen WD30, or set the position and size of the continuous registration confirmation screen WD30. In addition to the setting of , the transparency of the continuous registration confirmation screen WD30 may be set.

<Third Embodiment>
Next, a third embodiment will be described.
According to the description of the first embodiment, in order for a customer to purchase three or more identical products, the customer-side scanner unit 206 sequentially transmits product codes for each of these three or more identical products. When an operation to read is attempted, a continuous registration confirmation screen WD30 is displayed as follows.
In other words, the customer performs an operation to cause the POS terminal 20 to read the product code of the first same product to execute product registration, and then performs an operation to read the product code of the second same product. The POS terminal 20 is caused to execute product registration. At this stage, the POS terminal 20 determines that the same product has been registered twice in a row, so first, the first consecutive registration confirmation screen WD30 is displayed corresponding to the same product.
The customer operates the confirmation button BT30 on the displayed first consecutive registration confirmation screen WD30 to erase the first consecutive registration confirmation screen WD30.
Next, the POS terminal 20 executes product registration by performing an operation to read the product code of the third same product. As a result, the POS terminal 20 again determines that the same product has been registered twice in succession, and displays the second consecutive registration confirmation screen WD30 corresponding to the same product.
For example, if the customer intends to purchase the fourth and subsequent same products, the customer operates the confirmation button BT30 on the second consecutive registration confirmation screen WD30 to erase the second consecutive registration confirmation screen WD30, and 4 A similar procedure is performed for each registration of the same product, such as reading the product code of the first same product and registering the product.
In this manner, in the process in which the customer sequentially registers three or more identical products, the continuous registration confirmation screen WD30 is displayed each time the second and subsequent identical products are registered.

In the third embodiment, in the continuous registration confirmation screen WD30 displayed each time the second and subsequent same products are registered, the number of consecutive registrations (continuous registration number) to be displayed.

FIG. 8 shows a transition example of the display mode of the continuous registration confirmation screen WD30 (WD30-1 to WD30-3) in this embodiment.
When the customer performs product registration in accordance with the reading of the first same product code and subsequently performs product registration in accordance with the reading of the same first product code, the POS terminal 20 The registration confirmation screen WD30-1 is displayed.
A continuous registration number area AR30 is arranged on the continuous registration confirmation screen WD30-1. The number of consecutive registrations area AR30 shows the number of consecutive registrations for the same product. The number of consecutive registrations indicates the number of corresponding identical products registered consecutively. Also, the number of consecutive registrations can be regarded as indicating the number of times the same product has been registered in succession.
The continuous registration confirmation screen WD30-1 is displayed in response to the second registration of the same product. Therefore, the number of consecutive registrations is indicated as "2" in the consecutive registration number area AR30 of the consecutive registration confirmation screen WD30-1.

The customer operates the confirmation button BT30 on the continuous registration confirmation screen WD30-1 to erase the continuous registration confirmation screen WD30-1, and then performs the third operation to read the product code of the same product. The POS terminal 20 registers the third same product in response to reading the product code of the third same product.
The POS terminal 20, by registering the third same product in this manner, determines that the same product has been registered twice consecutively since the second registration of the same product. . Therefore, the POS terminal 20 displays the second consecutive registration confirmation screen WD30-2.
Up to this point, the same target product has been registered three times in succession. Therefore, the consecutive registration number area AR30 of the consecutive registration confirmation screen WD30-2 shows that the number of consecutive registrations is "3".

Next, the customer operates the confirmation button BT30 on the continuous registration confirmation screen WD30-2 to clear the continuous registration confirmation screen WD30-2. Next, the customer performs an operation to read the product code of the fourth same product following the second same product. The POS terminal 20 registers the fourth same product in response to reading the product code of the fourth same product.
The POS terminal 20 thus registers the same product for the fourth time, and thus determines that the same product has been registered twice consecutively from the previous registration of the same product for the third time. . Therefore, the POS terminal 20 displays the third consecutive registration confirmation screen WD30-3.
Up to this point, the same target product has been registered four times in succession. Therefore, the consecutive registration number area AR30 of the consecutive registration confirmation screen WD30-3 indicates that the number of consecutive registrations is "4".

In this way, in the process in which the customer sequentially reads the product code of the same product and continuously registers the same product, the continuous registration confirmation screen WD30 is displayed each time the second and subsequent same products are registered. Is displayed.
In addition, in the present embodiment, a continuous registration number area AR30 is provided in the continuous registration confirmation screen WD30 displayed in this manner, and the continuous registration number for the same product thus far is shown in the continuous registration number area AR30. make it
Since the number of consecutive registrations is displayed on the consecutive registration confirmation screen WD30 in this way, the customer can immediately grasp how many identical products have been consecutively registered so far by looking at the consecutive registration confirmation screen WD30. can.

It should be noted that the manner in which the number of consecutive registrations is indicated as the number of consecutive registrations area AR30 is not particularly limited. For example, the number of consecutive registrations may be indicated by the number of images of marks arranged in a predetermined manner.

<Fourth Embodiment>
Next, a fourth embodiment will be described. The product sales data processing system of this embodiment includes a mobile terminal owned by a customer, a settlement device installed in a store, and a transaction management server installed on the cloud. The mobile terminal and the settlement device are each communicably connected to the transaction management server. The mobile terminal may be owned by the customer, or may be prepared in advance at the store and lent to the customer who does the shopping.
In the merchandise sales data processing system of this embodiment, the customer himself/herself uses a mobile terminal to register merchandise at the store, and the customer himself/herself uses the settlement device installed in the store to settle the account according to the merchandise registration result. Corresponds to the self-style, which was made to do.

The mobile terminal used by the customer for product registration may be, for example, a smart phone. In this case, a shopping application corresponding to the self-service product sales data processing system of the present embodiment may be installed in a portable terminal as a smartphone owned by the customer.

With reference to FIG. 9, an example of a procedure for a customer to checkout in the merchandise sales data processing system of this embodiment will be described.
A customer activates a shopping application on a mobile terminal when starting shopping at a store. The mobile terminal on which the shopping application is activated connects with the transaction management server on the cloud. Also, the mobile terminal on which the shopping application is activated transmits, for example, its own location information to the transaction management server. Thereby, the transaction management server identifies the store where the mobile terminal is used. The mobile terminal and the transaction management server can execute accounting-related processing corresponding to the specified store (that is, the store where the customer shopped).

FIG. 9A shows an example of a shopping application startup screen displayed on the display unit of the mobile terminal. The name of the store (store name) specified as described above is displayed on the startup screen in FIG.
When the customer starts product registration for shopping, the customer operates a transaction start instruction button BT10 arranged on the startup screen.
In response to the operation of the transaction start instruction button BT10, the mobile terminal transmits a transaction start request including the customer identification information to the transaction management device. The customer identification information is generated and stored in the mobile terminal when a user account is registered with the shopping application.

The transaction management device that receives the transaction initiation request from the mobile terminal generates cart information corresponding to the requested transaction. The cart information is information indicating the product registration result. Cart identification information is added to the cart information. The transaction management server transmits a transaction start response including the cart identification information attached to the cart information to the mobile terminal.

The mobile terminal that has received the transaction start response displays a product registration screen. FIG. 9B shows an example of the product registration screen initially displayed in response to the reception of the transaction start response.
On the product registration screen, a captured image area AR1 and a product registration result area AR2 are arranged. The captured image area AR1 is an area in which a captured image obtained by capturing an image with a camera included in the mobile terminal is displayed. The product code imaged so as to fit within a predetermined range in the imaged image displayed in the imaged image area AR1 is to be read.
The product registration result area AR2 shows the number of registered products (registration points) and the total price corresponding to the products registered so far, and lists items corresponding to each registered product. area.

The customer picks up a product to be purchased at the store, for example, from the product shelf while holding the mobile terminal with the product registration screen displayed as described above or attaching it to the holder of the shopping cart. The customer causes the mobile terminal to scan (read) the product code by causing the camera of the mobile terminal to image the product code attached to the product taken out.

The portable terminal executes product registration processing in response to scanning the product code. There are two modes of cart information processing in accordance with product registration processing.
In one aspect, the mobile terminal transmits the scanned product code to the transaction management server each time one product code is scanned (read), thereby showing the product registration result synchronized between the mobile terminal and the transaction management server. This is an aspect in which cart information is shared.
In another aspect, first, the mobile terminal updates the product registration information each time the product code is scanned by the mobile terminal. Then, when the customer completes the registration of all the products and performs a checkout shift instruction operation (an operation on the checkout shift button BT2), the mobile terminal reflects the product registration results corresponding to all the product code scans so far. Send product registration information to the transaction management server. In other words, the mobile terminal collectively transmits the product registration information to the transaction management server upon completion of product registration. The transaction management server generates cart information for the corresponding transaction based on the received product registration information.
In the following explanation, as cart information processing according to product registration processing, the transaction management server generates cart information based on the product registration information collectively transmitted by the mobile terminal upon completion of product registration as in the latter case. Take for example the case where

In response to scanning the product code, the portable terminal executes product registration processing so as to include the product information of the scanned product code in the product registration information. Also, the mobile terminal reflects the registration result of the product corresponding to the scanned product code on the product registration screen.
That is, the portable terminal displays the list items Itm of the products that have been registered so far in the product registration result area AR2, as shown in FIG. 9C. In response to the new registration of one product by scanning one product code, a list item Itm indicating the product corresponding to the product code scanned this time is added to the product registration result area AR2.
Information such as the product name and price (unit price) indicated in the list item Itm is obtained, for example, based on the product master transmitted by the transaction management server as a response to the transaction start request. Alternatively, the information such as the product name and price (unit price) indicated in the list item Itm may be acquired based on information related to the product included in the product code.

After completing the registration of all the products to be purchased, the customer operates the checkout transfer button BT2 on the product registration screen. In response to the operation of the settlement transfer button BT2, the portable terminal transmits product registration information indicating the results of product registration thus far to the transaction management server. The transaction management server uses the received product registration information to generate corresponding transaction cart information.

In response to the operation of the checkout transfer button BT2, the portable terminal displays a checkout transfer screen instead of the product registration screen that has been displayed so far.
FIG. 9D shows an example of the settlement transfer screen. A cart identification code CD indicating the cart identification information of the cart information corresponding to the current transaction is displayed on the checkout transition screen. The cart identification code CD in this case is a two-dimensional code, but it may be a bar code (one-dimensional code), for example.

When the registration shift button BT20 on the settlement shift screen is operated, the mobile terminal returns the display to the product registration screen immediately before the settlement shift screen is displayed, for example, so that the product can be registered again.

The customer goes to the checkout device installed in the store to checkout after product registration. If multiple checkout devices are installed in the store, the customer may go to any checkout device at his/her own discretion.
The customer performs an operation to cause the code scanner of the checkout device to read the cart identification code CD in the checkout transition screen displayed on the portable terminal.
The settlement device transmits a cart information request including the cart identification information indicated by the read cart identification code CD to the transaction management server. The transaction management server transmits cart information identified by the same cart identification information included in the received cart information request to the checkout device.
The checkout device uses the received cart information to execute checkout processing according to the customer's operation. Completion of the settlement process means that the accounting corresponding to one transaction has been completed. After this, the customer can leave the store with the purchased product.

With reference to FIG. 10, an example of the operation of the mobile terminal when the same product is registered twice in succession in the product registration process under the accounting performed as described above will be described.
First, the customer registers one "potato chips" product by scanning the product code of one "potato chips" product with a mobile terminal. Next, in order to register another product as "bottle coffee", the customer performs an operation to scan the product code attached to the "bottle coffee" product with the portable terminal.

FIG. 10A shows a product registration screen displayed on the portable terminal according to the result of product registration as described above. In the product registration result area AR2 of the product registration screen of FIG. The list item for the product "bottle coffee" is arranged on the second line. The product registration result area AR2 shows that the number of registered points is 2 and the total amount is 230 yen.

In this embodiment, when the same product code is read twice consecutively, the portable terminal displays a continuous registration confirmation screen for allowing the customer to confirm that the same product code has been read twice consecutively. indicate.

One of the cases in which the same product code is read twice consecutively is that the customer intends to purchase a plurality of the same products, and causes the product codes of the same products to be read.

Another problem is that the same product code may be read twice consecutively by reading the product code of the product placed in the shopping cart after registration as follows.
In this embodiment, the portable terminal is attached to a holder of the shopping cart. When attached to the holder of the shopping cart, the portable terminal is in a state of capturing an image of the inside of the shopping cart.
Under this condition, the customer puts one bottle of "bottle coffee", which has been registered by reading the product code, into the shopping cart. At this time, when the camera of the mobile terminal captures the image of "bottle coffee" in the shopping cart, the product code of "bottle coffee" is determined to be read and is read. There is
When the product code of "bottle coffee" in the shopping cart is scanned, the same product code is scanned twice consecutively.

In this embodiment, when the same product code is read twice consecutively, the registration of the same product for the second time is suspended. After that, the continuous registration confirmation screen is displayed.

FIG. 10B shows an example of the continuous registration confirmation screen WD40. The continuous registration confirmation screen WD40 in the figure shows an example in the form of a dialog window arranged on the product registration screen.
In this embodiment as well, the continuous registration confirmation screen WD40 is positioned at the top of the product registration screen, so that the continuous registration confirmation screen WD40 and the product registration result area AR2 are visible. As a result, the customer can check the product registration results up to now by looking at the product registration result area AR2 while the continuous registration confirmation screen WD40 is being displayed. Also in the present embodiment, the position and size at which the continuous registration confirmation screen WD40 is displayed may be determined so that the product registration result area AR2 is not hidden.
At this time, the registration of the same product for the second time is suspended as described above. Therefore, the contents of the product registration result shown in the product registration result area AR2 of the product registration screen displayed as the background of the continuous registration confirmation screen WD40 are not changed from FIG. 10A.

In the continuous registration confirmation screen WD40, a product name area AR41, a message area AR42, a quantity setting area AR43, a registration instruction button BT41, and a non-registration instruction button BT42 are arranged.

The product name area AR41 is an area in which the product name of the product corresponding to the product code scanned twice in succession is indicated.

The message area AR42 displays a message informing the customer that the registration of the product corresponding to the first scan of the product code has already been completed because the same product code has been scanned twice in succession. It is an area where
The figure shows an example of notifying that registration of the product corresponding to the first scan of the product code has already been completed, and that one corresponding product is already in the shopping cart. It is

The registration instruction button BT41 is a button for instructing registration of a product whose registration has been suspended in response to the second product code scan.
The non-registration instruction button BT42 is a button for performing an operation to instruct not to register a product whose registration has been suspended in response to the second product code scan.

The quantity setting area AR43 is an area in which an operation for designating the quantity to be registered can be performed in response to the registration of products whose registration is pending. The customer can change the registered quantity by operating the plus button BT31 and the minus button BT342 in the quantity setting area AR43.
A registered quantity area AR431 in the quantity setting area AR43 is an area in which the currently set registered quantity is indicated.
A price area AR432 in the quantity setting area AR43 is an area where the price of the product corresponding to the currently set registration quantity is indicated.

If the continuous registration confirmation screen WD40 is displayed because the product code of the product that has been registered and put into the shopping cart has been inadvertently scanned, the same product whose product code is scanned for the second time will be displayed. Registration is not required. In this case, the customer operates the non-registration instruction button BT42.
In response to the operation of the non-registration instruction button BT42, the continuous registration confirmation screen WD40 is erased, and the same product registration screen that has been displayed so far is displayed in the foreground. In this case, as shown in FIG. 10(C), the product registration result shown in the product registration result area AR2 is unchanged from that shown in FIG. 10(B).

On the other hand, when the continuous registration confirmation screen WD40 is displayed because the customer intended to purchase the same product multiple times and had the product codes of the same products read, the product code was scanned for the second time. The same product should be registered. In this case, the customer operates the registration instruction button BT41 after setting the registration quantity by operating the quantity setting area AR43 of the continuous registration confirmation screen WD40 as necessary.
Also when the registration instruction button BT41 is operated, the continuous registration confirmation screen WD40 is erased and the product registration screen is displayed in the foreground.
However, in this case, the mobile terminal executed the process of registering the same product whose product code was scanned for the second time in response to the operation of the registration instruction button BT41. For this reason, in the product registration result area AR2 of the displayed product registration screen, as shown in FIG. is shown. Specifically, in FIG. 10B, in addition to the list item corresponding to one "potato chips" product on the first line and the list item corresponding to one "bottle coffee" product on the second line, Then, in the third line, a list item corresponding to one "bottle coffee" product is newly arranged.

As a modification of the present embodiment, when the same product code is read twice in succession, the mobile terminal completes the registration without suspending the registration of the same product for the second time, and then continuously reads the same product code. A registration confirmation screen WD40 may be displayed.
In this case, confirmation buttons similar to those shown in FIG. 6 may be arranged on the continuous registration confirmation screen WD40 in place of the registration instruction button BT41 and the non-registration instruction button BT42. When the confirmation button is arranged on the consecutive registration confirmation screen WD40 in this way, the area in which the operation for designating the registration quantity can be performed, such as the quantity setting area AR43, may be omitted.
In this case, if the customer does not intend to purchase the same product for which the product code is scanned for the second time, the customer is instructed to perform an operation to call a clerk when making the payment at the payment device. good. The store clerk responding to the call operates the settlement device to cancel the registration of any one of the two registered identical commodities and have the customer perform subsequent settlement.

<Modification>
Modifications of the above embodiment will be described below.

[First modification]
In each of the above-described embodiments, the POS terminal 20 or mobile terminal may emit a predetermined electronic sound (or a buzzer sound) each time the product code is read by the customer-side scanner unit 206 or camera. The customer can recognize that the product code has been successfully read by hearing the electronic sound generated in response to the product registration operation. In this case, if the POS terminal 20 or the mobile terminal determines that the same product code as that of the previous scan is read as a result of reading the product code this time, the POS terminal 20 or the mobile terminal emits a different electronic sound from the predetermined electronic sound. It may be made to emit an electronic sound. By changing the electronic sound in this way, it becomes easier for the customer to notice that the same product code has been read consecutively. In addition, even if the customer does not notice it, the store clerk in the surroundings can hear the electronic sound and notice that the same product code has been read in succession.

[Second modification]
In each of the above-described embodiments, the POS terminal 20 and the portable terminal detect that the product code was not successfully read when the customer-side scanner unit 206 or camera fails to read the product code. , may be announced to the customer as a voice message. For example, in notification by electronic sound, there is a possibility that the user may not perceive that the electronic sound is notifying that the product code was not read normally.

[Problems to be solved by the invention]
In a transaction using an information processing device compatible with full self-service, a product code is attached to the product as a bar code or the like. The customer registers the product by causing the information processing device to read the product code attached to the product.
In this case, although the customer intended to have the product code read once, the information processing device may read the product code twice in succession. As an information processing device, it is preferable to appropriately conduct transactions in response to multiple readings of such product codes.
SUMMARY OF THE INVENTION The present invention has been made in view of such circumstances, and it is an object of the present invention to appropriately conduct transactions in response to a case where an information processing device continuously reads product codes according to customer's operations. With the goal.

[Means to solve the problem]
(1) One aspect of the present embodiment is a reading unit (for example, the customer-side scanner unit 206, a camera of a mobile terminal) that reads a product code according to the customer's own operation, and the product code read by the reading unit. registering means for registering the corresponding product; and display means for displaying information about the product registered by the registering means, wherein the display means displays the same product code when the same product code is continuously read by the reading means. an information processing device (for example, POS terminal 20, mobile terminal, product sales data processing device, product data processing device, sales data processing device, product registration device, registration device, etc.).

According to the above configuration, when the information processing device continuously reads the same product code, the product corresponding to the first read product code among the product codes read in succession has already been registered by the registration means. A continuous registration confirmation screen is displayed to indicate that registration has been completed.
As a result, if the customer intends to have the product code of two identical products read in succession, the customer will know that the product registration has been or should be performed according to the second product code reading. You can proceed with the subsequent accounting after acknowledging it.
On the other hand, if the product code of one product is unintentionally read twice in succession despite the fact that the product code of one product has been read, the customer sees the continuous registration confirmation screen and confirms the fact. Therefore, it is possible to carry out the checkout after properly processing assuming that the product was not registered in response to the second reading of the product code.
In this manner, according to the present embodiment, transactions can be appropriately performed in response to the case where the information processing device continuously reads the same commodity code according to the customer's operation.

(2) An aspect of the present embodiment is the information processing apparatus according to (1), wherein the display means visually recognizes at least part of an area presenting a list of products registered by the registration means. The confirmation screen is displayed according to a possible mode.

According to the above configuration, the continuous registration confirmation screen and the product registration result on the product registration screen are displayed so as to be visible on the same screen. Thereby, the customer can also check the registration status of the products up to now while the continuous registration confirmation screen is being displayed.

(3) An aspect of the present embodiment is the information processing apparatus according to (1) or (2), wherein the display means displays the confirmation screen including an operator (eg, registration instruction button BT41). Then, the registration means registers, based on the operation of the manipulator, a product corresponding to a product code read later among the same product codes read in succession.

According to the above configuration, it is possible to register the product corresponding to the second reading of the product code by operating the registration instruction button BT41 on the continuous registration confirmation screen WD40. In this case, the customer can instruct whether or not to perform the registration corresponding to the second reading of the product code by operating the continuous registration confirmation screen WD40.

(4) An aspect of the present embodiment is the information processing apparatus according to (1) or (2), wherein the display means displays the confirmation screen including an operator (eg confirmation button BT30). The registration means registers a product corresponding to a product code read later among the product codes read in succession, regardless of confirmation operation on the operator.

According to the above configuration, when the consecutive registration confirmation screen WD30 is displayed, it is possible to make it so that the product corresponding to the second reading of the product code has already been registered.
As a result, when the customer-side scanner unit 206 reads the product code of one product twice in succession, the continuous registration confirmation screen WD30 is displayed to indicate that the product has been redundantly registered. can notice. In addition, if the customer has read the product codes of the same two products in order, the same two products that have been read have already been registered when the continuous registration confirmation screen WD30 is displayed. It is also possible to prevent the customer from proceeding with the checkout while forgetting to register the second product.

(5) An aspect of the present embodiment is the information processing apparatus according to any one of (1) to (4), wherein the display means continuously displays the same product code by the reading means. In response to the reading, the number of times the same product code has been read (for example, the number of consecutive registrations) is displayed on the confirmation screen (for example, the number of consecutive registrations area AR30).

According to the above configuration, the continuous registration number is sequentially incremented in the continuous registration number area AR30 of the continuous registration confirmation screen WD30 that is displayed each time the customer-side scanner unit 206 sequentially scans the product codes of the same multiple products. It can be displayed like this: As a result, the customer can immediately grasp how many of the same product are currently registered by viewing the continuous registration confirmation screen WD30.

(6) One aspect of the present embodiment is an information processing device comprising reading means for reading a product code in response to an operation by a customer, registration means for registering a product corresponding to the product code read by the reading means, A program for functioning as display means for displaying information about a product registered by a registration means, wherein the display means displays the same product code when the same product code is continuously read by the reading means. A program for displaying a confirmation screen indicating that a product corresponding to a product code has already been registered by the registration means.
