Hereinafter, an embodiment of a terminal management device that can effectively display a sales promotion effect in an information terminal to further improve the sales promotion effect in a product sales system in which registration of a purchased product is performed by a customer who personally operates the information terminal and payment for the purchased product is also performed by the customer who personally performs the payment will be described with reference to the drawings.

First embodiment

Fig. 1 is an overall configuration diagram of a product sales system according to the present embodiment. The merchandise sales system includes a first server 10, a second server 20, a POS terminal 30, a checkout machine 40, an information terminal 50, and a monitoring terminal 60. The first server 10, the second server 20, the POS terminal 30, and the checkout machine 40 are connected to a network 70 such as a LAN (local area network).

The information terminal 50 and the monitoring terminal 60 each have a wireless unit. An access point 80 is connected to the network 70. The information terminal 50 and the monitoring terminal 60 wirelessly communicate with the access point 80. The access point 80 relays communication between the devices connected to the network 70, that is, the first server 10, the second server 20, the POS terminal 30, and the checkout device 40, and the information terminal 50 and the monitoring terminal 60.

There may be a plurality of POS terminals 30, check-out devices 40, and information terminals 50 in a store. The monitoring terminal 60 and the access point 80 may have two or more depending on the size of the store. At least one of the first server 10 and the second server 20 communicates with the customer terminal through a public network. The customer terminal is, for example, a tablet terminal, a smart phone, a personal computer, or the like owned by the customer. A public network such as the internet. In the present embodiment, the first server 10 is connected to the public network as a central server. The second server 20 communicates with the POS terminal 30 as a shop server.

Fig. 2 is a schematic diagram showing an example of the layout of a store into which the merchandise sales system is introduced. A shopping cart used when a customer M1, which is a purchaser or a consumer, makes a shopping in a store includes the information terminal 50. In the following description, the shopping cart is referred to as cart C. The customer is a user of the information terminal 50. The information terminal 50 may be provided with a cart or a shopping basket. Customer M1 pushes cart C to stroll and loads the cart C with the merchandise to be purchased. The customer M1 operates the information terminal 50 to register the purchased product. When the registration of the purchased commodity is finished, the customer M1 goes to the face-to-face cash register G1 or the self-service cash register G2, and settles the commodity transaction by paying the payment for the purchased commodity. After settlement, the customer M1 bags on the checkout station SU as needed.

In the face-to-face cash register G1, a cashier M2, which is a clerk in charge of checkout, registers and settles the purchased commodities. The face-to-face cash register G1 has a POS terminal 30. The face-to-face cash register G1 has a scanner. The scanner may be either stationary or hand-held. The cashier M2 scans the barcode of the purchased article one by the scanner SC, and registers sales data of the purchased article with the POS terminal 30. The POS terminal 30 calculates the amount of settlement of the registered purchased products. The customer M1 pays the cash register M2 the payment of the amount corresponding to the settlement amount. The payment of the goods can be made through cash, credit card, electronic money, points, commodity voucher and other cash substitutes. The POS terminal 30 is an example of a commodity sales processing device that processes registration and payment of purchased commodities.

The self-service cash register G2 registers and settles the purchased merchandise by the customer M1. The self-service cash register G2 has a checkout machine 40. The second server 20 calculates the settlement amount of the purchased product registered by the customer M1 operating the information terminal 50. The second server 20 notifies the checkout machine 40 of the settlement amount thereof via the network 70. The customer M1 pays the payment amount corresponding to the settlement amount to the checkout machine 40 whose settlement amount has been notified. The payment for the goods may be made by cash, credit card, electronic money, points, etc.

The payment of the money for goods is not limited to the conventional payment method such as credit card and cash, and may be code scanning payment such as WeChat payment, Paibao payment, and Baidu wallet payment, or may be Apple Pay, NFC (near field communication) payment, scanning payment, payment circle, financial payment, inclusive payment, Unionpay, and new payment means appearing in the future, and the payment method for settlement is not particularly limited as long as the payment method is capable of paying the money for goods or the service fee.

The service desk AT is located near the self-service cash register G2. As described above, in the store of the present embodiment, the customer M1 operates the information terminal 50 and the checkout machine 40, and the registration of purchased commodities to the settlement can be performed consistently by the customer himself. On the other hand, however, it is inevitable that a situation is created in which a clerk must pass. For example, a customer M1 who purchases a medicine may have to be provided with information by a special salesperson. In some cases, the information of the discount label is forgotten to be input to the information terminal 50 and is registered at a normal price. Alternatively, the information terminal 50 may scan the barcode of the product and fail to register the barcode due to an error. There may also be a case where an error such as a coin jam, a bill break, or the like occurs in the checkout machine 40.

To be able to quickly cope with such an event, the attendant M3, which is a clerk responsible for reception, resides AT the helpdesk AT. AT the service station AT, there is a monitoring terminal 60. The attendant M3 monitors the states of the information terminals 50 and the checkout machines 40 by the monitoring terminal 60.

Next, the configurations of the first server 10, the second server 20, the information terminal 50, and the monitoring terminal 60 will be described. The POS terminal 30 may be the same POS terminal used in a store having an existing face-to-face cash register G1. The checkout device 40 may be the same as a checkout device used in a merchandise sales system of the semi-self-service system. The configuration of the POS terminal 30 and the checkout device 40 will not be described.

First, the configuration of the first server 10 will be described.

Fig. 3 is a block diagram showing a configuration of a main circuit of the first server 10. The first server 10 has a processor 11, a main memory 12, a secondary storage device 13, a communication interface 14, a gateway device 15, and a system transmission line 16. The system transmission line 16 includes an address bus, a data bus, a control signal line, and the like. The first server 10 connects the processor 11, the main memory 12, the auxiliary storage device 13, the communication interface 14, and the gateway device 15 to the system transmission line 16. The first server 10 constitutes a computer by means of a processor 11, a main memory 12 and an auxiliary storage device 13, and a system transmission line 16 connecting these devices.

The processor 11 corresponds to the central part of the above-described computer. The processor 11 controls each section to realize various functions as the first server 10 in accordance with an operating system and/or an application program. The processor 11 is, for example, a CPU (Central Processing Unit).

The main memory 12 corresponds to a main memory portion of the above-described computer. The main memory 12 includes a nonvolatile memory area and a volatile memory area. The main memory 12 stores an operating system and/or application programs in a non-volatile storage area. The main memory 12 sometimes stores data necessary for the processor to execute processing for controlling each section in a nonvolatile or volatile storage area. The main memory 12 uses a volatile area as a work area in which data can be appropriately rewritten by the processor. The nonvolatile Memory area is, for example, a ROM (Read Only Memory). The volatile Memory area is a RAM (random access Memory).

The auxiliary storage device 13 corresponds to an auxiliary storage section of the computer. For example, an EEPROM (electrically Erasable Programmable Read-Only Memory), an HDD (hard disk Drive) or an SSD (Solid State Drive) or the like is used as the auxiliary storage device 13. The auxiliary storage device 13 stores data used when the processor 11 performs various processes and/or data created by processes in the processor 11. The auxiliary storage device 13 sometimes stores the above-described application program.

The communication interface 14 transmits and receives data to and from each unit connected via the network 70 according to a communication protocol. The gateway device 15 is connected to a public network.

The first server 10 has a goods database 131, a member database 132, and a promotion database 133 in the secondary storage device 13. In fig. 3, the database is abbreviated as DB.

The product database 131 stores data on each product sold in the store. Fig. 4 is a schematic diagram showing a main data structure of the product data record 131R for each product stored in the product database 131. As shown in fig. 4, the product data record 131R includes items such as a product ID, a product name, a price, a classification name, a link promotion ID, and a restriction flag.

The product ID is a unique code set for each product to identify each product. The product name and price are the name of the product designated (specified) by the product ID and the selling price of each product.

The classification name is information that specifies a classification to which the product specified by the product ID belongs. For example, the product "apple" includes a plurality of varieties such as "fuji", "qianyin" and "ruby", and different product IDs are set for each variety. However, the classification name is unified as "apple" regardless of the variety.

The linked promotion ID is a code for identifying promotion information associated with the product specified by the product ID among promotion information stored in the promotion database 133. The sales promotion information associated with the product is, for example, information on a campaign that can be attended by purchasing the product, information on an item for which a discount is to be offered, information on a coupon that can be obtained, and the like. In addition, when the sales promotion information is not associated with the article, Null value is set as the link sales promotion ID. In the present embodiment, the sales promotion information associated with one product is regarded as one, but two or more sales promotion information may be associated.

The restriction flag is one-bit information for identifying whether or not the article designated by the article ID is an article with age restriction such as liquor, tobacco, or the like. In the present embodiment, the limit flag of a product with age restriction is regarded as "1", and the limit flag of a product without age restriction is regarded as "0".

The member database 132 stores data on so-called members of customers who have registered with members such as points. Fig. 5 is a schematic diagram showing a main data structure of the member data record 132R of each member held in the member database 132. As shown in fig. 5, the member data record 132R contains items such as member ID, purchase history data, and shopping data. The member ID is a unique code set for each member to identify each member. The member has a storage medium in which a member ID is recorded. The storage medium is, for example, a magnetic card, a contact (contact) IC (Integrated Circuit) card, a noncontact (noncontact) IC card, a smart phone, or the like. The purchase history data is data indicating a purchase history of what time the member specified by the member ID purchases.

The shopping data is data of goods that the member designated by the member ID has subscribed to purchase. The customer can access the first server 10 via the public network, such as by operating a customer terminal, and register purchase data in his or her member data record 132R. The shopping data contains the names of the commodities for which purchase has been scheduled. The name may be a product name set in the product data record 131R or a classification name. That is, as for the product "apple", regardless of the variety, a customer who intends to purchase registers the name "apple" as shopping data. On the other hand, a customer who intends to purchase a commodity "apple" such as "fuji apple" as a trade name only has to register the name "fuji apple" as shopping data.

The promotion database 133 stores promotion information related to the above-described promotional activities, special offers, coupons, and the like. Fig. 6 is a schematic diagram showing a main data structure of the promotion data record 133R for each piece of information held in the promotion database 133. As shown in FIG. 6, the promotion data record 133R includes a promotion ID and promotion data. The promotion ID is a unique code that is set for each piece of identification promotion information corresponding to each piece of promotion information. The promotion data is image data specifically representing promotion information. By regarding the promotion ID and the linked promotion ID of the article data record 131R as the same, the association between the article specified by the article ID and the promotion information can be realized. As described above, in the case where one item is associated with one piece of promotional information, when two or more pieces of promotional information are associated with one item, the linked promotional ID includes a plurality of promotional IDs.

Next, the configuration of the second server 20 will be described.

Fig. 7 is a block diagram showing a main circuit configuration of the second server 20. The second server 20 includes a processor 21, a main memory 22, a secondary storage device 23, a communication interface 24, and a system transmission line 25, as in the first server 10.

The checkout machine 40 has a printer for printing a bill. The checkout machine 40 becomes a printer error, such as when there is no ticket paper. When a printer error occurs, the first error flag EF1 changes from "0" to "1". Thereafter, when the error is eliminated, the first error flag EF1 returns from "1" to "0".

The area B4 is an area for describing the second error flag EF2 indicating whether or not an error has occurred in the change machine of the checkout machine 40 with one bit of information. The checkout machine 40 has a function of a change machine for collecting cash and paying change. The checkout machine 40 becomes a change machine error, such as when a coin jam occurs. When a change machine error occurs, the second error flag EF2 changes from "0" to "1". Thereafter, when the error is eliminated, the second error flag EF2 returns from "1" to "0".

Next, the configuration of the monitoring terminal 60 and the information terminal 50 will be described.

Fig. 16 is a flowchart showing the sequence of main information processing performed by the processor 51 of the information terminal 50. Fig. 17 to 27 are flowcharts showing the sequence of main information processing performed by the processor 21 of the second server 20. Fig. 28 to 32 and 37 are examples of images displayed on the touch panel 55 as a display device of the information terminal 50. Fig. 33 to 36 show an example of an image displayed on the touch panel 65 as a display device of the monitoring terminal 60. Hereinafter, the main operation of the product sales system according to the present embodiment will be described with reference to the drawings. The following description of the processing is an example. The order of processing and the content of processing are not particularly limited as long as the same result can be obtained.

First, an operation of the information terminal 50 will be described.

As Act1 of fig. 16, the processor 51 of the information terminal 50 displays an initial image on the touch panel 55. The initial image is arbitrary. The processor 51, for example, takes an image explaining the order of login as an initial image. The image data of the initial image is accepted from the second server 20. Processor 21 of second server 20 transmits the image data of the initial image to information terminal 50 whose terminal state ST1 is "on standby". The information terminal 50 in standby for login displays an initial image on the touch panel 55.

When the customer M1 who is a member comes to the store, the empty cart C is taken out from the cart placement place. The customer M1 confirms that the initial image is displayed on the touch panel 55 of the information terminal 50 to which the cart C is attached. After confirmation, the customer M1 logs in. That is, the customer M1 causes the reader 57 to read the data of the storage medium in which the member ID is recorded.

The processor 51 waits to accept the login as Act 2. When the reader 57 reads the data of the storage medium in which the member ID is recorded, the processor 51 determines that login is performed, and advances to YES in Act 2. The processor 51 controls the wireless unit 54 as Act3 so as to transmit a login instruction to the second server 20. The wireless unit 54 wirelessly transmits the login instruction. The login command includes the member ID read by the reader 57 and the terminal ID of the information terminal 50. The access point 80 receives a login instruction. The access point 80 sends a login instruction to the second server 20 through the network 70.

The processor 21 of the second server 20 that has received the login instruction through the communication interface 24 starts a login interruption process shown in the flowchart of fig. 17. First, the processor 21 detects the terminal ID from the login command as Act 21. The processor 21 searches the information terminal table 221 as Act22, and searches for the terminal status ST1 associated with the terminal ID detected from the login command. In the following description, the terminal ID detected from the login command is referred to as a login terminal ID.

When the terminal state ST1 is "in standby", the processor 21 proceeds to YES in Act 22. The processor 21 detects the member ID from the login instruction as Act 23. The processor 21 controls the communication interface 24 as Act24 to make an authentication inquiry of the member ID to the first server 10. The communication interface 24 sends an authentication inquiry command. The authentication inquiry command contains a member ID. The first server 10 receives the authentication query instruction through the network 70.

The processor 11 of the first server 10 detects the member ID from the authentication query instruction. The processor 11 accesses the member database 132 and reads out the member data record 132R containing the member ID. When the member data record 132R of the member ID is not registered in the member database 132, the processor 11 controls the communication interface 14 so that a negative acknowledgement is transmitted to the second server 20. The communication interface 14 transmits a response signal denying the response to the second server 20.

The processor 11 controls the communication interface 14 so that an approval response is transmitted to the second server 20 when the conforming member data record 132R can be read out from the member database 132. The communication interface 14 sends a reply signal to the second server 20 approving the reply. The approval reply contains the shopping data of the member data record 132R.

The processor 21 of the second server 20 that has controlled the transmission of the authentication inquiry command waits for the acceptance of the response signal from the first server 10 as Act 25. If a response signal approving the response is received within a certain time, the processor 21 proceeds to YES in Act 25. The processor 21 confirms as Act26 whether or not shopping data is included in the approval reply.

When the registered customer M1 has previously registered the shopping data, the approval response includes the shopping data. When no shopping data is registered, no shopping data is included in the approval reply. When the shopping data is contained in the approval reply, the processor 21 proceeds to YES in Act 26. Processor 21 acts as Act27 to compile a shopping list L3 based on the shopping data. That is, the processor 21 adds a series of numbers to the names constituting the shopping data and creates the shopping list L3. The processor 21 holds a shopping list L3 in the area a11 associated with the login terminal ID of the information terminal table 221. The processor 21 changes all the fifth flags F5 corresponding to the respective numbers of the shopping list L3 to "0" as Act 28. When NO shopping data is contained in the approval reply, the processor 21 proceeds to NO in Act 26. The processor 21 does not perform the processing of Act27 and Act28 described above.

The processor 21 composes a registration image P1 shown in fig. 28 as Act 29. The processor 21 controls the communication interface 24 as Act30 so that an approval response is transmitted to the information terminal 50 of the login instruction transmission source. Further, the processor 21 controls the communication interface 24 as Act31 so that the image data of the login image P1 is transmitted to the information terminal 50. The communication interface 24 transmits a response signal approving the response and the image data of the registration image P1 through the network 70. The access point 80 wirelessly transmits the response signal and the image data. The information terminal 50 of the registration instruction transmission source receives the response signal and the image data wirelessly transmitted from the access point 80.

The processor 21 that has controlled the transmission of the response signal and the image data changes the terminal state ST1 associated with the registered terminal ID in the information terminal table 221 from "on standby" to "on registration" as Act 32. The processor 21 resets the value of the counter N associated with the registered terminal ID of the information terminal table 221 to "0" as Act 33. The processor 21 starts a timer operation of the first counter T1 associated with the registered terminal ID in the information terminal table 221 as Act 34.

In this way, the processor 21 ends the login interruption process.

When the terminal state ST1 is not "in standby", the processor 21 proceeds to NO in Act 22. When the answer from the first server 10 is a negative answer, the processor 21 proceeds to NO in Act 25. The processor 21 controls the communication interface 24 as Act35 so that a negative acknowledgement is transmitted to the information terminal 50 of the login instruction transmission source. The communication interface 24 transmits an acknowledgement signal denying the acknowledgement through the network 70. The access point 80 wirelessly transmits an acknowledgement signal denying the acknowledgement. The information terminal 50 of the registration instruction transmission source receives the response signal of the negative acknowledgement wirelessly transmitted from the access point 80.

The explanation returns to fig. 16.

The processor 51 of the information terminal 50 that has controlled the transmission of the login command in Act3 waits for the reception of the response signal from the second server 20 as Act 4. When receiving the response signal of the negative acknowledgement through the wireless unit 54, the processor 51 proceeds to NO in Act 4. The processor 51 treats the login as an error. When the login is an error, the processor 51 causes the touch panel 55 to display an error notification image including a confirmation button. The processor 51 returns the image of the touch panel 55 to the initial image if the confirmation button has been touched, and waits for acceptance of the next login.

When the processor 51 receives the answer signal authorizing the answer through the wireless unit 54, the processor 51 proceeds to YES in Act 4. As Act5, a login image P1 is displayed on the touch panel 55 based on the image data received simultaneously with the approval response.

Fig. 28 is a schematic diagram showing an example of the registration image P1. As shown in fig. 28, the registration image P1 includes a login list area PA1, a promotion list area PA2, a shopping record area PA3, a touch button BU1 for "no-barcode goods", and a touch button BU2 for "checkout".

The registration list area PA1 is located in the center of the registration image P1. The registration list area PA1 is an area for displaying the registration list L1 described in the area a9 associated with the registered terminal ID of the information terminal table 221. At a stage before the start of the product registration, the registration list area PA1 is blank.

The promotion list area PA2 is located on the upper part of the registration image P1. The promotion list area PA2 has a plurality of promotion areas along the upper end of the registration image P1. In fig. 28, four promotion areas PA21, PA22, PA23, PA24 are shown. The promotion areas PA21, PA22, PA23, and PA24 display the promotion information of the promotion list L2 described in the area a10 associated with the login terminal ID in the information terminal table 221. The promotion area PA21 facing the left end of the screen displays the promotion information newly registered in the promotion list L2. The promotion areas PA22, PA23, PA24 located on the right side of the promotion area PA21 with respect to the screen shift the promotion information registered up to this point in sequence. The promotion list area PA2 is also empty at a stage before the start of the registration of the merchandise. The sales promotion areas PA21, PA22, PA23, PA24 of the registration image P1 before the start of the commodity registration may also be made to display sales promotion information such as "tomorrow is special sale day" or the like that is not associated with the purchase of the commodity.

The purchase recording area PA3 is located at the left side portion of the screen facing the registration image P1. The purchase record area PA3 is an area for displaying the shopping list L3 described in the area a11 associated with the registered terminal ID of the information terminal table 221. When the registered customer M1 has registered shopping data in advance, the shopping record area PA3 displays information of the shopping list L3 based on the shopping data. When the registered customer M1 has not registered the shopping data in advance, the shopping record area PA3 is blank. Alternatively, the shopping record area PA3 itself may be omitted from the login image P1.

The touch button BU1 of "no-barcode merchandise" and the touch button BU2 of "checkout" are located at the lower part of the registration image P1. Specifically, the left side of the screen has a touch button BU1 for "no barcode product" and the right side has a touch button BU2 for "checkout". The arrangement of the touch button BU1 and the touch button BU2 may also be reversed left to right.

The touch button BU1 of "bar code free article" is used by the customer when registering an article without a bar code with the information terminal 50. A barcode corresponding to a product ID of a large number of products sold in a store is attached to the products. Therefore, the customer M1 who makes a self-service registration with the cart C operates the scanner 56 to read the barcode attached to the purchased article before loading the article into the basket BA in the store. By reading the barcode with the scanner 56, the article ID represented by the barcode thereof is input to the information terminal 50. That is, the product registration is performed. On the other hand, a barcode may not be attached to a part of a product such as a fresh food. When no barcode is attached to the purchased article, the customer M1 touches the touch button BU 1. By doing so, since a touch button corresponding to a product to which no barcode is attached, a so-called product button, is displayed on the touch panel 55, the customer M1 touches the product button corresponding to a shopping product. When the product button is touched, the product ID of the product corresponding to the product button is input to the information terminal 50. That is, the product registration is performed.

The touch button BU2 of "check out" is used by the customer when announcing the check out of the purchased merchandise. That is, the customer M1 who has performed self-service registration of purchasing commodities with the cart C touches the touch button BU2 at the time of transition to checkout.

The explanation returns to fig. 16.

The processor 51 that has displayed the registration image P1 on the touch panel 55 in Act5 confirms as Act6 whether or not the product registration has been performed. When NO commodity registration is made, the processor 51 proceeds to NO in Act 6. The processor 51 confirms as Act7 whether the touch button BU2 of "checkout" has been touched. When the touch button BU2 of "checkout" is not touched, the processor 51 advances to NO in Act 7. The processor 51 returns to Act 6. Here, the processor 51 waits for the touch button BU2 accepting commodity registration or "check out" to be touched in Act6 and Act 7.

In the wait-for-acceptance state of Act6 and Act7, when the commodity registration is confirmed, the processor 51 proceeds to YES in Act 6. The processor 51 controls the wireless unit 54 as Act8 so as to transmit the article registration instruction to the second server 20. The wireless unit 54 wirelessly transmits the article registration instruction. The product registration instruction includes the terminal ID of the information terminal 50 and the product ID of the registered product. That is, when the barcode of the registered article is read by the scanner 56, the article registration instruction contains the article ID obtained from the barcode. When a registered article is selected by a touch operation of the article button, the article registration instruction includes an article ID that has been assigned to the article button. The article registration instruction is received through the access point 80 and transmitted to the second server 20 through the network 70.

The processor 21 of the second server 20, which has received the commodity registration instruction through the communication interface 24, starts the commodity registration interrupt processing shown in the flowcharts of fig. 18 to 20. First, the processor 21 detects the product ID from the product registration instruction as Act 41. The processor 21 controls the communication interface 24 as Act42 to make an inquiry for the commodity data to the first server 10. The communication interface 24 transmits the commodity inquiry command. The article inquiry command contains an article ID. The article inquiry command is transmitted to the first server 10 through the network 70.

The processor 11 of the first server 10 that receives the article inquiry instruction through the communication interface 14 detects the article ID from the article inquiry instruction. The processor 11 accesses the product database 131 and reads out the product data record 131R including the product ID. When the article data record 131R of the article ID cannot be read out from the article database 131, the processor 11 controls the communication interface 14 so that an abnormal response is transmitted to the second server 20. The communication interface 14 transmits a response signal of the abnormal response to the second server 20.

When the matching article data record 131R can be read out from the article database 131, the processor 11 controls the communication interface 14 so that a normal response is sent to the second server 20. The communication interface 14 transmits a response signal of a normal response to the second server 20. The normal response contains the article data of the article ID, article name, price, classification name, link promotion ID, restriction flag, and the like of the article data record 131R.

The processor 21 of the second server 20 that has controlled the transmission of the commodity inquiry command waits for the reception of the response signal from the first server 10 as Act 43. If the answer signal of the normal answer is received within a certain time, the processor 21 proceeds to YES in Act 43. The processor 21 adds the commodity data included in the normal response to the registration list L1 of the information terminal table 221 as Act 44. That is, the processor 21 adds the product ID, the product name, the number of items, and the amount of money to the registration list L1 of the area a9 associated with the terminal ID included in the product registration instruction in the information terminal table 221. The product ID and the product name are included in the product data. The number of pieces is "1". The amount is the price of the merchandise data. In the following description, the terminal ID included in the product registration command is referred to as a registration terminal ID. The processor 21 changes the first to third flags F1 to F3 of the commodity data added thereto to "0" as Act 45.

The processor 21 determines as Act46 whether the registered article is a tag-attached article. In this embodiment, a discount label indicating discount information is attached to a product to be subjected to discount, and a discount mark is attached to a part of a barcode. The discount information is such as a discount amount or discount rate. When the image of the barcode picked up by the scanner 56 of the information terminal 50 contains a discount label, the processor 21 determines that the registered item is an item with a discount label. When the registered article is not a tag-attached article, the processor 21 proceeds to NO in Act 46. The processor 21 proceeds to the processing of Act 53.

When the registered article is an article with a discount label, the processor 21 proceeds to YES in Act 46. The processor 21 starts, as Act47, a counter counting operation of the second timer T2 associated with the registered terminal ID of the information terminal table 221. The processor 21 confirms as Act48 whether or not the discount information is received. When the discount information is not received, the processor 21 proceeds to NO in Act 48. The processor 21 confirms as Act49 whether the second timer T2 has timed out. For example, the second timer T2 times out when it finishes counting 15 seconds. When the second timer T2 has not timed out, processor 21 proceeds to NO in Act 49. Processor 21 returns to Act 48. The processor 21 waits for reception of the discount information or the second timer T2 becomes timeout in Act48 and Act 49.

When a discount label is attached to a purchased article, the customer M1 in self-check-in needs to operate the scanner 56 to read the information of the discount label. When the registered article is an article with a discount label, the processor 21 may cause the touch panel 55 of the information terminal 50 to display guidance instructing reading of the discount label by the scanner 56.

When the discount information is read in the scanner 56 of the information terminal 50, the wireless unit 54 wirelessly transmits the discount information. The discount information is received by the access point 80 and sent to the second server 20 via the network 70.

When the processor 21 of the second server 20 detects that the discount information is received through the communication interface 24 before the second timer T2 times out, the processor 21 proceeds to YES in Act 48. The processor 21 performs the discount process as Act 50. For example, the processor 21 acquires a discount amount from the discount information, and subtracts the discount amount from the amount added to the commodity data in the registration list L1 in the process of Act 44. The processor 21 stops the second timer T2 as Act 51. After that, the processor 21 proceeds to the processing of Act 53.

When the second timer T2 has timed out, the processor 21 proceeds to YES in Act 49. The processor 21 changes the second flag F2 of the commodity data added to the registration list L1 in the process of Act44 from "0" to "1" as Act 52. After that, the processor 21 proceeds to the processing of Act 53. When the customer M1 causes the scanner 56 to read the information of the discount label before the second timer T2 times out, the registered commodity is written in the registration list L1 by the discount information of the discount label being discounted. However, when the second timer T2 has timed out, the registered merchandise is not discounted but described in the registration list L1. That is, the registered article becomes a discount tag read error. The second flag F2 becomes "1" with respect to the registered article in which the tag-reading error is discounted.

In Act53, the processor 21 looks up the limit flag for the merchandise data. When the restriction flag is "0", that is, the registered commodity is a commodity without age restriction, the processor 21 proceeds to NO in Act 53. The processor 21 proceeds to Act61 of fig. 19.

When the restriction flag is "1", that is, the registered article is an article with age restriction, the processor 21 proceeds to YES in Act 53. The processor 21 changes the third flag F3 added to the commodity data in the registration list L1 in the process of Act44 from "0" to "1" as Act 54. That is, the third flag F3 becomes "1" with respect to the age-restricted registered commodity.

The processor 21 controls the communication interface 24 as Act55 so that the image data of the age confirmation image is transmitted to the information terminal 50 of the product registration instruction transmission source. The processor 21 proceeds to Act61 of fig. 19. The communication interface 24 transmits the image data of the age confirmation image through the network 70. The access point 80 wirelessly transmits the image data. The information terminal 50 of the product registration instruction transmission source receives the image data wirelessly transmitted from the access point 80.

In the information terminal 50 that receives the image data of the age confirmation image, the age confirmation image is displayed on the touch panel 55. An age confirmation image such as that showing "do you be over 20 years? "the confirmation button is displayed simultaneously with the guidance, and therefore, the customer M1 who confirms the age confirmation image touches the confirmation button. By so doing, the age confirmation image is erased, and the screen of the touch panel 55 returns to the registration image P1.

When the processor 21 fails to receive the response signal of the normal response within a certain time period with respect to the transmission of the commodity inquiry command, it proceeds to NO in Act 43. The processor 21 executes a virtual article registration process. For example, there may be a case where the product data record 131R of the registered product is deleted from the product database 131. At this time, the processor 21 cannot receive the response signal of the normal response. The processor 21 adds only the product ID of the registered product to the registration list L1 as the virtual product registration processing. The product names, the number of pieces, and the amount of money are not added to the registration list L1. The processor 21 sets the first flag F1 of the product data to which only the product ID is added to "1" and sets both the second flag F2 and the third flag F3 to "0" as Act 58. The processor 21 proceeds to Act61 of fig. 19. The first flag F1 becomes "1" with respect to the merchandise item registered by the virtual merchandise item registration processing.

In Act61, the processor 51 creates a registration list image from the registration list L1 of the area a9 of the information terminal table 221 associated with the registered terminal ID. The registration list image is an image displayed in the registration list area PA1 of the registration image P1. That is, as shown in fig. 28, the registration list image is an image in which the product names, the number of products, and the amount of money of the product data registered in the registration list L1 are arranged in a list. The arrangement order is such that the newly registered product is higher, that is, the registration number of the registration list L1 is in descending order from larger to smaller. The registration number is represented as "No.", in fig. 9. The product data newly added to the registration list L1 can be recognized by, for example, making the character color different from other product data or making the background color different. The example of fig. 28 shows a case where the background color is made different. Each commodity data is displayed with a "cancel" touch button BU 3. When the purchase of the commodity corresponding to the commodity data is suspended in the middle of the purchase, the touch button BU3 of "cancel" is touched by the customer M1. When the touch button BU3 of "cancel" has been touch-operated, the number of pieces and the amount of money of the matching merchandise item of the registration list area PA1 become "0". The "cancel" touch button BU3 is deleted.

The processor 21 confirms as Act62 whether or not promotion information is set in association with the registered product. That is, the processor 21 looks up the link promotion ID contained in the merchandise data in the answer signal of the normal answer received in Act 43. When the link promotion ID is Null, the processor 21 determines that promotion information is not set. When a code as a link promotion ID is set, the processor 21 determines that promotion information is set. When NO promotion is set, the processor 21 proceeds to NO in Act 62. The processor 21 proceeds to the processing of Act 71.

When the promotion information is set, the processor 21 proceeds to YES in Act 62. The processor 21 retrieves the promotion list L2 of the area a10 associated with the registered terminal ID of the information terminal table 221 as Act 63. The processor 21 confirms whether the linked promotion ID included in the article data is registered in the promotion list L2.

When the linked promotion ID is not registered in the promotion list L2, the processor 21 proceeds to NO in Act 64. The processor 21 acts as Act65 to control the communication interface 24 to query the first server 10 for promotional data. The communication interface 24 sends a promotional query instruction. The promotion query instruction contains a linked promotion ID. The promotional query instruction is sent to the first server 10 via the network 70.

The processor 11 of the first server 10 receiving the promotion query instruction via the communication interface 14 detects the linked promotion ID from the promotion query instruction. The processor 11 accesses the promotion database 133 and reads out the promotion data record 133R containing the linked promotion ID. When the promotion data record 133R for the promotion ID is not registered in the promotion database 133, the processor 11 controls the communication interface 14 so that a normal response without promotion is sent to the second server 20. The communication interface 14 sends a normal response to the second server 20 without promotion.

The processor 11, when able to read the conforming promotion data record 133R from the promotion database 133, controls the communication interface 14 so that a normal response containing the promotion data is sent to the second server 20. The communication interface 14 sends a normal response containing the promotion data to the second server 20.

The processor 21 of the second server 20, which controls the transmission of the promotion inquiry instruction, confirms as Act66 whether a normal response containing the promotion data is received. When a normal response without promotion is received, the processor 21 proceeds to NO in Act 66. The processor 21 proceeds to the processing of Act 71.

When a normal response containing promotional data is received, the processor 21 proceeds to YES in Act 66. The processor 21 increments the count of the counter N of the area a8 associated with the registered terminal ID of the information terminal table 221 by "1" as Act 67. The processor 21 adds data as Act68 to the promotion list L2 of the area a10 associated with the registered terminal ID of the information terminal table 221. The data includes a product ID of a registered product, a link promotion ID associated with the product ID, and promotion data in which the link promotion ID is set. Data is added to the area having the same number as the counter N.

When the link promotion ID has been registered in the promotion list L2, the processor 21 proceeds to YES in Act 64. The processor 21, as Act69, moves (shifts) the link promotion ID, the promotion data registered in the promotion list L2 together with the link promotion ID, and the article ID to the same-numbered area as the counter N.

When the processing of Act68 or Act69 is finished, the processor 21 changes the fourth flag F4 of the same-numbered area as the counter N of the promotion list L2 to "1" as Act70, and changes the fourth flag F4 of the other-numbered area to "0". Thereafter, the processor 21 proceeds to Act 71. The fourth flag F4 becomes "1" for the promotion information associated with the newly registered merchandise.

In Act71, processor 21 confirms whether counter N counts a value greater than "0". When counter N is "0", processor 21 proceeds to NO in Act 71. The processor 21 proceeds to Act81 of fig. 20.

When the counter N is larger than "0", the processor 21 proceeds to YES in Act 71. The processor 21 creates a promotion image from the promotion list L2 of the area a10 associated with the registered terminal ID of the information terminal table 221 as Act 72. When the processor 21 finishes composing the promotion image, it proceeds to Act81 of fig. 20.

The promotion image is an image displayed in the promotion list area PA2 of the registration image P1. That is, as shown in fig. 28, the promotion image is an image in which promotion information generated from promotion data registered in the promotion list L2 is arranged in the area PA21, the area PA22, the area PA23, and the area PA24, respectively. Specifically, the promotion information is displayed to the area PA21, the area PA22, the area PA23, and the area PA24 in descending order of the number of the promotion list L2. The promotion information generated from the promotion data whose fourth flag F4 is "1", that is, the promotion information displayed by the area PA21, can be identified from the promotion information displayed by the other areas PA22, PA23, and PA 24. For example, the color of the frame and the background color are set to the same color as the character color and the background color of the registered product newly added to the registration list area PA1 only in the area PA21, so that the registered product can be identified from other sales promotion information. The example of fig. 28 shows a case where the background color is the same as the background color of the newly added registered product.

The processor 21 has a function as an image generating section (image generating step) by executing the processing of Act61 to Act72 in cooperation with the communication interface 24 as a communication section. The image generation unit generates a registration image P1 of a registration list area PA1 including an image indicating a purchased product in one screen area and a promotion list area PA2 in which images of promotion information related to the purchased product are arranged based on the registration order of the purchased product, based on the registration of a newly purchased product in the information terminal 50. The image generating unit deletes the image of the sales promotion information in the oldest registration order from the images included in the sales promotion list area PA2, and adds the image of the sales promotion information related to the newly purchased product to the sales promotion area PA21 which is the arrangement position of the image of the sales promotion information in the newest registration order in the sales promotion list area PA2, thereby generating a registration image P1 including the image of the sales promotion information. In the example of FIG. 28, the number of images of promotional information is four.

The processor 21 executes the process of performing Act68 by executing Act65 in cooperation with the communication interface 24 as a communication unit, and has a function of inquiring the first server 10 as a server storing sales promotion information associated with a product for registration of a new purchased product in the information terminal 50 about sales promotion information associated with the purchased product, acquiring the sales promotion information from the server 10, and adding a control unit described in the second table secured in the main memory 22 as a storage unit. The second table may be a promotion list L2 in which promotion information acquired and ensured by the information terminal table 221 ensured in the main memory 22 is described for each information terminal 50.

The processor 21 has a function as a control unit that associates the promotion information related to the purchased product with information indicating the storage order of the promotion information and describes the promotion information in the second table secured in the main memory 22 by executing the processing of Act67 and Act 69.

The processor 21 has a function as a control section that, when the promotion information associated with a newly purchased article has been stored in the second table of the main memory 22 at the time of registration of the purchased article in the information terminal 50, newly associates the conforming promotion information in the second table with the information indicating the latest storage order by executing the processing of Act64 and Act 69.

In Act81, the processor 21 determines whether or not the purchase list L3 is held in the area a11 associated with the registered terminal ID of the information terminal table 221. When shopping list L3 is not saved, processor 21 proceeds to NO in Act 81. The processor 21 proceeds to Act 86.

When shopping list L3 is saved, processor 21 proceeds to YES in Act 81. Processor 21 retrieves the shopping list L3 as Act 82. The processor 21 confirms as Act83 whether or not the registered commodity is contained in the shopping list L3. That is, the processor 21 confirms whether a name that coincides with the trade name or the classification name of the registered commodity exists in the shopping list L3. When there is NO consistent name, the processor 21 proceeds to NO in Act 83. The processor 21 proceeds to Act 85.

When there is a consistent name, the processor 21 proceeds to YES in Act 83. The processor 21 changes the fifth flag F5 corresponding to the name of the shopping list L3 that matches the name from "0" to "1" as Act 84. The processor 21 then proceeds to Act 85. The fifth flag F5 is "1" with respect to the name of the commodity registered with the commodity among the names described in the shopping list L3.

In Act85, processor 21 composes a shopping record image with information of shopping list L3. When finishing compiling the shopping record image, the processor 21 proceeds to Act 86.

The shopping record image is an image displayed in the shopping record area PA3 of the registration image P1. That is, as shown in fig. 28, the processor 21 forms a shopping record image by arranging the names registered in the shopping list L3 in order from the top to the bottom of the screen. The processor 21 erases the name of the fifth flag F5 as "1". For example, the processor 21 erases by drawing a deletion line on the name of "1" of the fifth flag F5. Alternatively, the processor 21 erases the name with the fifth flag F5 being "1" by making the character density lighter than the other names.

In Act86, the processor 21 compiles a registration image P1. That is, the processor 21 compiles the registration image P1 in such a manner that the registration list image compiled in Act61, the promotion image compiled in Act72, and the shopping record image compiled in Act85 are displayed in the areas PA1, PA2, and PA3, respectively.

The processor 21 controls the communication interface 24 as Act87 to cause the registration image P1 to be transmitted to the information terminal 50 of the commodity registration instruction transmission source. The communication interface 24 transmits the image data of the registration image P1 compiled in Act86 through the network 70. The access point 80 wirelessly transmits the image data. The information terminal 50 of the product registration instruction transmission source receives the image data wirelessly transmitted from the access point 80.

The processor 21 has a function as an output unit (output step) for outputting the registration image P1 to the information terminal 50 in cooperation with the communication interface 24 by the processing of Act 87.

The processor 21 that has controlled the transmission of the registration image P1 starts the counting operation of the third timer T3 associated with the registration terminal information ID of the information terminal table 221 as Act 88. When the third timer T3 has started, the processor 21 restarts the third timer T3. In this manner, the processor 21 ends the commodity registration interrupt processing.

The explanation returns to fig. 16.

The processor 51 of the information terminal 50 that has controlled the transmission of the commodity registration instruction in Act8 returns to Act 5. That is, the processor 51 updates the registration image P1 displayed on the touch panel 55 based on the image data newly received from the second server 20.

The product name, the number of products, and the amount of money of the product which the customer M1 registered by self are added to the registration list area PA 1. When the registered commodity exists in the shopping list L3, the name of the registered commodity is erased from the shopping record area PA 3. When promotion information is set in association with the registered product, a promotion image based on the promotion information is displayed in the promotion area PA21 of the promotion list area PA 2. When other promotion information has been displayed in the promotion areas PA 21-PA 23, the promotion areas PA 22-PA 24 on the right side in turn are shifted, and the promotion information displayed in the promotion area PA24 is not displayed. However, when the promotion information of the registered merchandise has been displayed in the promotion area PA21, the promotional image does not change. When the promotion information of the registered merchandise is displayed in the promotion area PA22, for example, the promotion information is moved into the promotion area PA21, and the promotion information displayed in the promotion area PA22 immediately before is shifted into the promotion area PA 22. The same is true when promotion information of registered merchandise has been displayed in the other promotion areas PA23, PA 24.

The processor 51 proceeds to YES in Act6 every time the commodity registration is performed. The processor 51 repeats the processing of Act8 and Act 5.

In addition, the first flag F1 becomes "1" with respect to the commodities registered by the virtual commodity registration processing. As shown in a display example PR1 of fig. 29, the name of the registered commodity having the first flag F1 of "1" is "commodity registration error". A guidance "confirmation by the worker at the time of checkout" is displayed instead of the number of pieces and the amount of money. An icon IC1 indicating a commodity registration error is displayed.

The second flag F2 becomes "1" with respect to the registered article in which the discount label reading error occurs. As shown in display example PR2 of fig. 29, the name of the registered product having the second flag F2 of "1" is "discount label error". A guidance "confirmation by the worker at the time of checkout" is displayed instead of the number of pieces and the amount of money. An icon IC2 indicating a discount label error is displayed.

With respect to the registered article with age restriction, the third flag F3 becomes "1". As shown in a display example PR3 of fig. 29, an icon IC3 indicating that the registered product whose third flag F3 is "1" is displayed.

The number of items and the amount of money may not be regarded as "0" in the registration list area PA1, with respect to the commodity whose cancellation is instructed by the touch operation of the "cancel" touch button BU 3. As shown in display example PR4 of fig. 29, a cancel line may be displayed for each product name, number of products, and price, and the "cancel" touch button BU3 may be erased. As shown in fig. 29, the order of arrangement of the error items such as "article registration error" and "discount label error" may be switched so as to be positioned at the upper level of the registration list area PA 1. The wrong items such as "article registration error" and "discount label error" may be stored in the order of arrangement in which the newly registered article is positioned higher, without changing the order of arrangement, as a reference for the customer M1 who searches for an article corresponding to the error from the shopping basket BA. The background color of the position of the scroll bar at the right end of fig. 29 corresponding to the row of the error item may be made different from the background color of the position not corresponding to the error item so that the position of the row of the error item such as "article registration error" or "discount label error" can be easily known.

The explanation returns to fig. 16.

When the touch button BU2 of "checkout" has been input in the standby accepted states of Act6 and Act7, the processor 21 proceeds to YES in Act 7. The processor 21 controls the wireless unit 54 as Act9 so that a checkout instruction is sent to the second server 20. The wireless unit 54 wirelessly transmits a checkout instruction. The checkout instruction includes the terminal ID of the information terminal 50.

The processor 21 of the second server 20 that has received the checkout instruction through the communication interface 24 starts a checkout interrupt process shown in the flowchart of fig. 21. First, the processor 21 searches the information terminal table 221 as the terminal ID included in the checkout instruction for Act 101. In the following description, the terminal ID included in the checkout command is referred to as a checkout terminal ID. The processor 21 confirms whether or not there is data in which the first flag F1 has been set to "1" in the registration list L1 in the area a9 associated with the checkout terminal ID.

When there is NO data for which the first flag F1 has been set to "1", the processor 21 proceeds to NO in Act 101. The processor 21 confirms as Act102 whether or not there is data in the registration list L1 for which the second flag F2 has been set to "1".

When there is also NO data for which the second flag F2 has been set to "1", the processor 21 proceeds to NO in Act 102. The processor 21 controls the communication interface 24 as Act103 so as to transmit the approval response to the information terminal 50 of the checkout instruction transmission source. The processor 21 controls the communication interface 24 as Act104 to transmit the image data of the shopping bag confirmation image P3 shown in fig. 31 to the information terminal 50. The communication interface 24 transmits a response signal approving the response and image data of the shopping bag confirmation image P3 through the network 70. The access point 80 wirelessly transmits the response signal and the image data. The information terminal 50 of the checkout instruction transmitter receives the response signal and the image data wirelessly transmitted from the access point 80.

When there is data in the registration list L1 in the Act101 for which the first flag F1 has been set to "1", the processor 21 proceeds to YES and proceeds to the processing of the Act 111. In Act102, when there is data for which the second flag F2 has been set to "1", the processor 21 proceeds to YES and proceeds to the processing of Act 111. The processor 21 controls the communication interface 24 as the Act111 so as to transmit the negative acknowledgement to the information terminal 50 of the checkout instruction transmission source. The processor 21 controls the communication interface 24 as Act112 so as to transmit the image data of the worker confirmation image P2 shown in fig. 30 to the information terminal 50. The communication interface 24 transmits the response signal of the negative response and the image data of the worker confirmation image P2 through the network 70. The access point 80 wirelessly transmits the response signal and the image data. The information terminal 50 of the registration instruction transmission source receives the response signal and the image data wirelessly transmitted from the access point 80.

The explanation returns to fig. 16.

The processor 51 of the information terminal 50 that controls the transmission of the settlement instruction in Act9 waits for the acceptance of the response signal from the second server 20 as Act 10. When receiving the response signal of the negative acknowledgement through the wireless unit 64, the processor 51 proceeds to NO in Act 10. The processor 51 causes the touch panel 55 to display the worker confirmation image P2 based on the image data received simultaneously with the response signal as Act 111.

Fig. 30 is a schematic diagram showing an example of display of the worker confirmation image P2. As shown in fig. 30, the staff confirmation image P2 includes guidance GA1 that notifies that the staff is required to confirm because of an error in the registration of a commodity by self-service, and further includes a touch button BU4 of "yes". The customer M1 who confirmed the staff confirmation image P2 goes to the service desk AT to report to the attendant M3.

The attendant M3, having received the report from the customer M1, performs an operation for deleting the data of the commodity whose first flag F1 was changed to "1" or whose second flag F2 was changed to "1" from the registration list L1. This operation may be performed from the monitoring terminal 60 or from the information terminal 50. Alternatively, the processing may be performed from the checkout machine 40, or may be performed after connecting another computer device to the network 70.

If the data of the merchandise item of which the first flag F1 becomes "1" or the second flag F2 becomes "1" has been deleted from the registration list L1, the customer M1 touches the touch button BU4 of "yes".

The processor 51, which controls the display of the worker confirmation image P2, waits for the acceptance confirmation operation to be performed as Act 12. The processor 51 proceeds to YES in Act12 if it detects that the touch button BU4 of YES as the confirmation operation has been touch-operated. The processor 51 returns to Act 5. That is, the processor 51 returns the screen of the touch panel 55 to the registration image P1.

The customer M1 who confirmed that the screen of the touch panel 55 returned to the registration image P1 touches the touch button BU2 of "checkout". By doing so, processor 21 of second server 20 becomes NO in Act101 and NO in Act102 in fig. 21, and therefore executes the processing of Act103 and Act 104. As a result, the information terminal 50 receives the response signal of the approval response and the image data of the shopping bag confirmation image P3.

When the answer signal that approves the answer is received by the wireless unit 54, the processor 51 proceeds to YES in Act 10. The processor 51 causes the touch panel 55 to display a shopping bag confirmation image P3 as Act13 based on the image data received simultaneously with the response signal.

Fig. 31 is a schematic diagram showing an example of display of a shopping bag confirmation image P3. As shown in fig. 31, the shopping bag confirmation image P3 includes a guide GA2 inquiring whether to purchase a shopping bag, and further includes a touch button BU5 of "purchase" and a touch button BU6 of "not purchase". When purchasing a shopping bag, a customer M1 who confirms a shopping bag confirmation image P3 touches and operates the touch button BU5 and goes to the service desk AT to receive the shopping bag. When the customer M1 does not purchase a shopping bag, the customer M1 touches the touch button BU6 and does not accept the shopping bag.

The processor 51 controls the wireless unit 54 as Act14 to cause the shopping bag information to be sent to the second server 20. The wireless unit 54 wirelessly transmits shopping bag information. The shopping bag information is information indicating shopping bags are purchased when the touch button BU5 of "purchase" is touch-operated in the shopping bag confirmation image P3, and information indicating non-shopping bags are not purchased when the touch button BU6 of "not purchase" has been touch-operated.

In Act104 of fig. 21, the processor 21 of the second server 20 that has controlled the transmission of the shopping bag confirmation image P3 waits for the reception of shopping bag information as Act 105. When shopping bag information indicating purchase of a shopping bag is received, the processor 21 proceeds to YES in Act 105. The processor 21 appends the sales data of the shopping bags as Act106 to the registration list L1. When shopping bag information indicating that a shopping bag is not purchased is received, the processor 21 proceeds to NO in Act 105. Processor 21 skips the processing of Act 106.

When the cost of the shopping bag is fixed, the sales data of the shopping bag can be preset. When the cost of the shopping bags differs depending on the size or the like, the barcode of the shopping bag is scanned by the scanner 56 when the shopping bag is received. When the barcode of the shopping bag is scanned, the sales data of the shopping bag is added to the registration list L1 in the same order as in the normal commodity registration.

The processor 21 issues a new checkout code as Act 107. The checkout code is, for example, a unique code that combines a date and a series of transaction numbers and is not duplicated with other checkout codes. The processor 21 stores the checkout code in the area a12 associated with the checkout terminal ID of the information terminal table 221.

The processor 21 acts as Act108 to convert the checkout code to a barcode and encodes the checkout barcode image P4 shown in fig. 32. The processor 21 controls the communication interface 24 so as to transmit the checkout barcode image P4 to the information terminal 50 of the checkout instruction transmission source. The communication interface 24 transmits the image data of the checkout barcode image P4 through the network 70. The access point 80 wirelessly transmits the image data. The information terminal 50 of the checkout instruction transmission source receives the image data wirelessly transmitted from the access point 80.

The processor 21 that controls the transmission of the image data of the checkout barcode image P4 changes the terminal state ST1 associated with the checkout terminal ID of the information terminal table 221 from "registration" to "checkout" as Act 110. When the process of Act110 or the process of Act112 described above is finished, the processor 21 stops the counting operation of the third timer T3 associated with the checkout terminal ID in the information terminal table 221 as Act 113. In this way, the processor 21 ends the checkout interrupt process.

The explanation returns to fig. 16.

In Act14, the processor 51 of the information terminal 50 that has transmitted the shopping bag information waits as Act15 for receipt of the checkout barcode image P4. When the image data of the checkout barcode image P4 is received through the wireless unit 54, the processor 51 proceeds to YES in Act 15. The processor 51 causes the touch panel 55 to display a checkout barcode image P4 based on the image data as Act 16. In this way, the processor 51 ends the post-login processing.

Fig. 32 is a diagram showing an example of display of the checkout barcode image P4. As shown in fig. 32, the checkout barcode image P4 contains a barcode BC representing a checkout code. The customer M1 who confirmed the checkout barcode image P4 proceeds to the checkout machine 40 in a vacant state at the self-service cash register G2, and reads the barcode BC of the checkout barcode image P4 by a scanner connected to the checkout machine 40.

When the scanner barcode BC has been read by the checkout machine 40, the checkout machine 40 transmits a checkout request instruction including a checkout code obtained from the barcode BC and a checkout machine ID unique to the checkout machine to the second server 20 through the network 70.

The processor 21 of the second server 20 that has received the checkout request instruction starts the checkout request terminal process of fig. 22. First, the processor 21 detects a checkout code included in the checkout request instruction as Act 121. The processor 21 searches the information terminal table 221 as Act122, and searches for the terminal status ST1 associated with the terminal ID that stores the same checkout code as area a 12. In the following description, the terminal ID storing the same checkout code as in the area a12 is referred to as a checkout request terminal ID. When the terminal state ST1 is not "check out", the processor 21 proceeds to NO in Act 122. The processor 21 ends the interrupt processing as an error.

When the terminal state ST1 is "check out", the processor 21 proceeds to YES in Act 122. The processor 21 stores, as Act123, the checkout machine ID included in the checkout request instruction in the area a4 associated with the checkout request terminal ID in the information terminal table 221. The processor 21 controls the Act124 so as to transmit the registration list L1 stored in the area a9 associated with the checkout request terminal ID in the information terminal table 221 to the checkout machine 40 of the checkout request instruction transmission source. Then, the processor 21 searches the checkout table 222 as Act125, and changes the checkout state ST2 corresponding to the checkout ID included in the checkout request command to "payment in progress". As described above, the processor 21 ends the checkout request interrupt process.

The communication interface 24 transmits the data of the registration list L1 to the checkout machine 40 through the network 70. The checkout machine 40 can perform a checkout process from the data of the registration list L1. The customer M1 pays the checkout machine 40 the payment of the settlement amount calculated from the data of the registration list L1. When the checkout process is completed, the checkout device 40 transmits a checkout completion instruction including the same checkout code and checkout device ID as the checkout request instruction to the second server 20 via the network 70.

The processor 21 of the second server 20 that has received the checkout end instruction starts the checkout end interrupt process of fig. 23. First, the processor 21 detects a checkout code included in a checkout end instruction as Act 131. The processor 21 searches the information terminal table 221 as Act132, and searches for the terminal state ST1 associated with the terminal ID in which the same checkout code as the area a12 is stored. In the following description, the terminal ID storing the same checkout code as in the area a12 is referred to as a checkout end terminal ID. When the terminal state ST1 is not "check out", the processor 21 proceeds to NO in Act 132. The processor 21 ends the interrupt processing as an error.

When the terminal state ST1 is "check out", the processor 21 proceeds to YES in Act 132. The processor 21 searches the checkout table 222 as Act133, and changes the checkout state ST2 corresponding to the checkout ID included in the checkout end command to "idle". The processor 21 searches as Act134 the shopping list L3 of the area a11 associated with the checkout end terminal ID of the information terminal table 221. The processor 21 determines as Act135 whether or not there is data in which the fifth flag F5 is set to "1". When there is data in the shopping list L3 in which the fifth flag F5 has been set to "1", the processor 21 proceeds to YES in Act 135. Processor 21 compiles a shopping list L3 as Act 136. That is, the processor 21 deletes data of which the fifth flag F5 has been set to "1" from the shopping list L3. When there is NO data in the shopping list L3 for which the fifth flag F5 has been set to "1", the processor 21 proceeds to NO in Act 135. Processor 21 does not perform the processing of Act 136.

After that, the processor 21 performs control in such a manner that the member data is transmitted to the second server 10 as Act 137. The member data includes the member ID of the area A3, the registration list L1 of the area a9, and the shopping list L3 of the area a11, which are associated with the checkout end terminal ID in the information terminal table 221.

The processor 11 of the first server 10 that has received the settlement data adds the data of the registration list L1 included in the settlement data to the purchase history data of the member database 132 specified by the member ID included in the settlement data. The processor 11 changes the shopping data in the member database 132 to the data of the shopping list L3 included in the checkout data.

The processor 21 of the second server 20 that controls the transmission of the settlement data initializes information associated with the settlement end terminal ID of the information terminal table 221 as Act 138. That is, processor 21 clears the membership ID of area A3, the check-out ID of area a4, the registration list L1 of area a9, the promotion list L2 of area a10, the shopping list L3 of area a11, and the check-out code of area a 12. The processor 21 resets the values of the first timer T1 of the region a5, the second timer T2 of the region a6, and the third timer T3 of the region a9 to "0". Also, the processor 21 resets the value of the counter N of the area A8 to "0".

After that, the processor 21 changes the state ST1 associated with the checkout end terminal ID in the information terminal table 221 from "checkout" to "standby" as a 139. As described above, the processor 21 ends the checkout end interrupt process.

In addition, the customer M1 who operated the information terminal 50 provided on the cart C to perform self-service registration can complete checkout even at the face-to-face cash register G1. When the checkout is performed at the face-to-face cash register G1, the cashier M2 inputs the terminal ID of the information terminal 50 to the POS terminal 30. For example, the information terminal 50 is attached with a barcode indicating a terminal ID. The cashier M2 scans the barcode with the scanner and inputs the terminal ID. Alternatively, the information terminal 50 is attached with an RFID tag that wirelessly transmits a terminal ID. The cashier M2 inputs the terminal ID by reading the data of the RFID tag with the RFID reader connected to the POS terminal 30.

When the terminal ID is input, a face-to-face checkout instruction is transmitted from the POS terminal 30 to the second server 20 through the network 70. The face-to-face checkout instruction contains the terminal ID that has been input in the POS terminal 30.

The processor 21 of the second server 20 that has received the face-to-face checkout instruction starts the face-to-face checkout interruption process of fig. 24. First, the processor 21 detects a terminal ID included in the face-to-face checkout instruction as Act 141. The processor 21 looks up the terminal status ST1 associated with the terminal ID included in the face-to-face checkout instruction of the information terminal table 221 as Act 142. In the following description, the terminal ID included in the face-to-face checkout command of the information terminal table 221 is referred to as a face-to-face terminal ID. When the terminal state ST1 is "on standby", the processor 21 proceeds to YES in Act 142. The processor 21 ends the face-to-face checkout interrupt process.

When the terminal state ST1 is not "in standby", the processor 21 proceeds to YES in Act 142. The processor 21 initializes the information related to the face-to-face terminal ID of the information terminal table 221 as Act143 as described above. After that, the processor 21 changes the terminal status ST1 associated with the face-to-face terminal ID in the information terminal table 221 to "standby" as Act 144. In this way, the processor 21 ends the face-to-face checkout interrupt process.

The terminal state ST1 being "on standby" means that the customer M1 is not registered with the information terminal 50. That is, the customer M1 completes the check-out in the face-to-face cash register G1 without self-check-in. At this time, even if the terminal ID of the information terminal 50 is input to the POS terminal 30, the processor 21 of the second server 20 does not execute the processing of Act143 and Act 144.

When the terminal state ST1 is such as "in registration", it means that the customer M1 who has logged in to the information terminal 50 has completed checkout in the face-to-face cash register G1. At this time, the member ID is described in the area a3 associated with the terminal ID of the information terminal 50 in the information terminal table 221. When the customer M1 registers shopping data, a shopping list L3 is stored in the area a 11. When the customer M1 makes a self-check-in, a registration list L1 and a promotion list L2 are stored in the area a9 and the area a10, respectively. If the terminal state ST1 is returned to "standby" without initializing these areas, the information terminal 50 cannot be used. The processor 21 can return the information terminal 50 used by the customer M1 who switched from self-service registration to the face-to-face cash register G1 to a usable state by executing the processing of Act143 and Act 144.

In addition, when the clerk M2 forgets to input the terminal ID of the information terminal 50 to the POS terminal 30 at the time of checkout at the face-to-face cash register G1, the terminal ID may be lost. When the terminal ID is forgotten to be input, data relating to the information terminal 50 is retained in the information terminal table 221 even when the checkout is completed. The terminal status ST associated with the terminal ID of the information terminal 50 is "registered". Therefore, since the next customer cannot log in to the information terminal 50, the cart C is placed.

The third timer T3 is restarted each time the processor 21 of the second server 20 executes the commodity registration interrupt process. When the processor 21 executes the checkout interrupt process, the third timer T3 is stopped. In other words, after the commodity registration interruption process is executed in accordance with the commodity registration instruction, if the state in which the next commodity registration instruction or checkout instruction is not received from the information terminal 50 of the commodity registration instruction transmission source continues, the processor 21 continues to count the time by the third timer T3 corresponding to the terminal ID of the information terminal 50.

Fig. 25 is a flowchart showing the procedure of timer monitoring processing executed by the processor 21 of the second server 20. The processor 21 starts the timer monitoring process, such as at one minute intervals. That is, the processor 21 confirms the counted time of the third timer T3 as Act 151. The processor 21 determines as Act152 whether or not there is a third timer T3 counting a preset first threshold time TM1, such as five minutes. When the counted time of the third timer T3 associated with all the terminal IDs is less than the first threshold time TM1, the processor 21 proceeds to NO in Act 152. The processor 21 ends the timer monitoring process.

When the counted time of the at least one third timer T3 is equal to or greater than the first threshold time TM1, the processor 21 proceeds to YES in Act 152. The processor 21 looks up as Act153 the terminal state ST1 corresponding to the third timer T3 which counts the first threshold time TM 1. When the terminal state ST1 is "in registration", the processor 21 proceeds to YES in Act 153. The processor 21 changes the terminal status ST1 from "during registration" to "put" as Act 154. When the terminal state ST1 is not "in registration", the processor 21 proceeds to NO in Act 153. The processor 21 does not perform the processing of Act 154. As described above, the processor 21 ends the timer monitoring process.

In this way, the information terminal 50 to which the cart C having been placed is set, the terminal state ST1 is managed as "placed" in the information terminal table 221. The member ID is described in the area A3 of the information terminal table 221 associated with the terminal ID whose terminal state ST1 is "set". When the customer registers shopping data, a shopping list L3 is stored in the area a 11. When the customer performs self-check-in, a registration list L1 and a promotion list L2 are stored in the area a9 and the area a10, respectively. If the terminal state ST1 is returned to "standby" without initializing these areas, the information terminal 50 cannot be used as described above.

Further, in the present embodiment, data of the information terminal table 221 relating to the information terminal 50 set to the cart C that has been placed can be initialized by remote operation from the monitoring terminal 60. Next, the operation of the monitoring terminal 60 will be described.

Fig. 33 shows an example of a monitor image P11 displayed on the touch panel 65 as the display device of the monitor terminal 60. In this example, the number of the checkout machines 40 is three.

In the monitor image P11, a total of 15 status display units (T1) to T15 are arranged in a matrix of five rows × three columns. Three state display units (T1) to (T3) from the first row to the third row in the first column are checkout machine state display units Ta that display the state of the checkout machine 40. The state display units (T4) and (T5) in the fourth row and the fifth row in the first column and the state display units (T4) to (T15) in the second column and the third column are terminal state display units Tb that display the state of the information terminal 50.

For example, the shape, size, background color, and the like of the state display units (T1) to (T15) are uniform. In this regard, for example, the checkout machine state display unit Ta and the terminal state display unit Tb may be differentiated by making at least a part of the shape, size, background color, and the like different from each other.

Further, the monitor image P11 includes a "active" touch button BU11, a "standby" touch button BU12, a "full station" touch button BU13, a monitor image layout button BU14, a detailed image layout button BU15, and the like. The arrangement and the number of the state display units of the monitor image P11 shown in fig. 33 are examples. Needless to say, the screen size of the touch panel 65 and the number of the checkout machines 40 and the information terminals 50 may be changed as appropriate.

Fig. 34 shows an example of the checkout device state display unit Ta. The checkout machine state display Ta includes a first region Ta1 facing the left side of the screen and a second region Ta2 facing the right side of the screen. The first area Ta1 displays the checkout ID of the checkout 40. The billing machine ID is "Q1" in fig. 34. In fig. 33, the account machine IDs are "Q1", "Q2", and "Q3". The second area Ta2 shows the state of the checkout machine 40. Specifically, the second area Ta2 shows a state in which the checkout device 40 is "idle" before the checkout process or "paying" for the checkout process. The display of such a state is based on the checkout state ST2 of the checkout table 222. Further, fig. 34 shows that the checkout machine 40 is "idle".

The second area Ta2 displays a flag MC1 that lights up when an error occurs in the printer in the checkout machine 40, and a flag MC2 that lights up when an error occurs in the change machine. When the first error flag EF1 of the checkout machine table 222 is "1", the flag MC1 is lit. When the second error flag EF2 of the checkout machine table 222 is "1", the flag MC2 is lit.

Fig. 35(a) to 35(E) show an example of the terminal state display unit Tb. The terminal state display part Tb includes a first area Tb1 facing the left side of the screen and a second area Tb2 facing the right side of the screen. The second area Tb2 shows the state of the information terminal 50. Specifically, the second area Tb2 shows the information terminal 50 in a state of "waiting", "registering", "settling", or "set". The display of such a state is based on the terminal state ST1 of the information terminal table 221. In addition, the terminal state display unit Tb shown in fig. 35(a) shows that the information terminal 50 is "on standby". The terminal state display unit Tb shown in fig. 35(B) and 35(C) indicates that the information terminal 50 is "registered". Terminal state display unit Tb shown in fig. 35(D) shows that information terminal 50 is "in payment". The terminal state display Tb shown in fig. 35(E) shows that the information terminal 50 is "set".

The second region Tb2 displays a sign MC3 that lights up when a commodity of "commodity registration error" is registered in the registration list L1, a sign MC4 that lights up when a commodity of "discount label error" is registered, and a sign MC5 that lights up when an age-restricted commodity is registered. When data of which the first flag F1 is "1" is present in the registration list L1, the flag MC3 is lit. When data of which the second flag F2 is "1" is present in the registration list L1, the flag MC4 is lighted. When data of which the third flag F3 is "1" is present in the registration list L1, the flag MC5 is lighted.

The first area Tb1 is an area where the state of the information terminal 50 can be recognized by color or the like. When a normal state in which an error or the like has not occurred in "standby", "in registration", or "in checkout", the first area Tb1 changes the background color to, for example, blue. The background color of the first region Tb1 of the terminal state display section Tb shown in fig. 35(a) and 35(D) is changed to blue. In the case of "checkout", the first field Tb1 displays the checkout ID of the checkout device 40 that has performed the checkout process. The checkout ID is displayed in the first area Tb1 of the terminal state display unit Tb shown in fig. 35 (D). When the attention of the staff is required due to registration of an age-restricted commodity in "registration", the first region Tb1 changes the background color to a color that encourages attention, such as yellow. The background color of the first region Tb1 of the terminal state display section Tb shown in fig. 35(B) is yellow. When the intervention of a worker is required in the checkout due to "commodity registration error", "discount label error", or the like in "registration", the first region Tb1 changes the background color to a color such as red to notify a warning. The background color of the first region Tb1 of the terminal state display section Tb shown in fig. 35(C) is changed to red. When "put", the first region Tb1 changes the background color to a color such as black that notifies another warning. The second area Tb2 displays the flag MC6 indicating the set state. The background color of the first region Tb1 of the terminal state display section Tb shown in fig. 35(E) is changed to black, and the indicator MC6 is displayed in the second region Tb 2.

Fig. 26 is a flowchart showing the procedure of the monitoring image preparation process executed by the processor 21 of the second server 20. The processor 21 starts the monitoring image preparation process, for example, at intervals of 10 seconds. First, the processor 21 selects the information terminal 50 whose terminal state ST1 is "check-out" from the information terminal table 221 as Act 161. The processor 21 sets the bit count from one bit to a bit in descending order of the count time value of the first timer T1 for the selected information terminal 50 as Act162, and stores the bit count in the area a13 of the information terminal table 221. The "a" digit is the number of digits corresponding to the number of information terminals 50 in "check out". When there is no information terminal 50 whose terminal state ST1 is "check out", the processor 21 does not perform the process of Act 162.

The processor 21 selects the information terminal 50 whose terminal state ST1 is "under registration" from the information terminal table 221 as Act 163. Processor 21 calculates the remaining number of pieces of shopping list L3 for each of the selected information terminals 50 as Act 164. The remaining number of pieces is the number of names with the fifth flag F5 being "1" subtracted from the number of names registered in the shopping list L3. When the shopping list L3 is not saved, the remaining number of pieces becomes a prescribed value such as "100". The processor 21 sets the bit numbers from a bit +1 to a bit + b in the order of the number of remaining bits from small to large as Act165 for the selected information terminal 50, and stores the bit numbers in the area a13 of the information terminal table 221. The b-bit is the number of bits corresponding to the number of information terminals 50 "under registration". The processor 21 determines as Act166 whether or not there are information terminals 50 having the same number of remaining items. When at least two or more customers who have not registered shopping data are registered, there are a plurality of information terminals 50 for the remaining number "100". When there are information terminals 50 having the same number of remaining pieces, the processor 21 proceeds to YES in Act 166. The processor 21 sets the bit count as Act167 in descending order of the count value of the first timer T1. When there is no information terminal 50 in the terminal state ST1 "login", the processor 21 does not perform the processing of Act164 to Act 167.

The processor 21 selects the information terminal 50 of the terminal state ST1 "put" from the information terminal table 221 as Act 168. The processor 21 sets the order of bits from a + b +1 bit to a bit + b bit + c bit in the order of the terminal ID set in the information terminal table 221 for the selected information terminal 50 as Act165, and stores the order in the area a13 of the information terminal table 221. The c bit is the number of bits corresponding to the number of information terminals 50 "placed". When there is no information terminal 50 in the terminal state ST1 "put", the processor 21 does not perform the processing of Act 169.

The processor 21 selects the information terminal 50 in the terminal state ST1 "on standby" from the information terminal table 221 as the Act 170. The processor 21 sets, as Act171, the order of bits from a + b + c +1 bit to a bit + b bit + c bit + d bit in the order of the terminal ID set in the information terminal table 221 for the selected information terminal 50, and stores the order in the area a13 of the information terminal table 221. The d bits are the number of bits corresponding to the number of information terminals 50 that are "on standby". When there is no information terminal 50 in the terminal state ST1 "on standby", the processor 21 does not perform the processing of Act 171.

The processor 21 generates a monitoring image P11 from the data of the information terminal table 221 and the checkout table 222 as Act 172. That is, the processor 21 creates the checkout machine state display unit Ta for the checkout machine 40 based on the checkout machine ID, the checkout machine state ST2, the first error flag EF1, and the second error flag EF2 in the checkout machine table 222. The processor 21 arranges the checkout machine state display unit Ta of each checkout machine 40 in the state display unit (T1), the state display unit (T2), and the state display unit (T3) of the monitor image P11.

The processor 21 creates a terminal state display section Tb for the information terminal 50 based on the terminal ID of the information terminal table 221, the terminal state ST1, and the first to third flags F1 to F3 of the registration list L1. The processor 21 selects the terminal state display portion Tb of each information terminal 50 from 1 bit to 12 bits in order of order, and arranges the selected terminal state display portion Tb to the state display portions (T4) to (T15) in the order from one bit.

When the processor 21 creates the monitor image P11, it controls the communication interface 24 as the communication unit to transmit the monitor image P11 to the monitor terminal 60 as Act 173. The communication interface 24 transmits the image data of the monitor image P11 through the network 70. The access point 80 wirelessly transmits the image data. The monitoring terminal 60 receives image data wirelessly transmitted from the access point 80. The touch panel 65 of the monitor terminal 60 displays a monitor image P11 shown in fig. 33.

When the touch button BU11 of "on duty" of the monitor image P11 has been touch-operated, the processor 21 executes monitor image preparation processing in which the processing of Act161 and Act162 and the processing of Act170 and Act171 of fig. 26 are omitted. The monitoring image P11 is limited to the terminal state display section Tb that shows the state of the information terminal 50 "at checkout", "under registration", or "in place". When the touch button BU12 of "standby" has been touch-operated, the processor 21 executes monitoring-image composing processing in which the processing of Act161 to Act169 of fig. 26 is omitted. The monitoring image P11 is limited to only the terminal state display unit Tb indicating the state of the information terminal 50 "on standby".

In addition, as shown in fig. 33, the monitor image P11 includes a touch button BU16 for turning pages. The checkout machine state display unit Ta and the terminal state display unit Tb become touch buttons.

As shown in fig. 26, the processor 21 of the second server 20, after controlling the transmission of the monitoring image, confirms as Act174 whether or not the touch button BU16 of the page turn has been touched. When the touch button BU16 is not touched, the processor 21 proceeds to NO in Act 174. The processor 21 checks as Act175 whether or not the checkout machine state display unit Ta or the terminal state display unit Tb has been touch-operated. When the checkout machine state display section Ta or the terminal state display section Tb is not touched and operated, the processor 21 proceeds to NO in Act 174. The processor 21 confirms as Act176 whether or not the timer interrupt signal is detected. When the timer interrupt signal is not detected, the processor 21 returns to Act 174. That is, the processor 21 waits for the touch button BU16 that has received the page turn to be touched, the checkout machine state display unit Ta or the terminal state display unit Tb to be touched, or the timer interrupt signal to be detected.

When the timer interrupt signal is detected, the processor 21 proceeds to YES in Act 176. The processor 21 again performs the processing from Act 161.

When the touch button BU16 of the page turn has been touch-operated, the processor 21 proceeds to YES in Act 174. Processor 21 returns to Act 172. That is, the processor 21 recomposes the monitor image P11. For example, the processor 21 creates the monitor image P11 of the terminal state display section Tb in which the status display sections (T1) to (T15) are arranged from 13 bits to 27 bits. When the attendant M3 touches and operates the touch button BU16 for turning pages, the terminal state display portion Tb2 of 13 to 27 digits in order is displayed in each of the state display portions (T1) to (T15).

The pattern of the monitor image P11 programmed by the processor 21 when the page-turning touch button BU16 has been operated is not limited to the above-described pattern. For example, the state display units (T1) to (T3) in which the checkout machine state display unit Ta is arranged may be constructed as fixed, and the monitor image P11 of the terminal state display unit Tb2 whose order is from 13 to 24 bits may be arranged for the remaining state display units (T4) to (T15).

When the checkout machine state display section Ta or the terminal state display section Tb has been touch-operated, the processor 21 proceeds to YES in Act 175. The processor 21 acquires the registration list L1 as Act 177. For example, when the state display unit Ta of the checkout device 40 in the state "payment" is touched and operated, the processor 21 searches the information terminal table 221, and acquires the registration list L1 in which the checkout device ID of the checkout device 40 is associated with the terminal ID described in the area a 4. When the terminal state display portion Tb of the information terminal 50 in the state "registration" has been touch-operated, the processor 21 detects the information terminal table 221, and acquires the registration list L1 associated with the terminal ID of the information terminal 50.

If the registration list L1 is acquired, the processor 21 returns to Act172 and creates the monitor image P11 again. Specifically, the processor 21 creates a monitoring image P11 including the touched checkout machine state display unit Ta or terminal state display unit Tb, and a detailed image showing the contents of the registration list L1 acquired in the process of Act177, such as the product name, the number of items, and the amount of money. The processor 21 controls the communication interface 24 as Act173 so as to transmit the monitor image P11 to the monitor terminal 60.

The attendant M3 can confirm the information on the purchased commodity of the customer M1 who is performing checkout in the checkout machine 40 whose state is displayed in the checkout machine state display Ta by touching, for example, the checkout machine state display Ta. The attendant M3 can confirm the information of the purchased article of the customer M1 who purchased the article with age restriction by touching the terminal state display section Tb such as the flag MC5 which is lighted and the first area Tb1 which is yellow. The attendant M3 can confirm the information of the purchased product of the customer M1 in which the "product registration error" or the "tag discount error" has occurred by touching the terminal state display section Tb such as the flag MC3 or the flag MC4 which is lit and the first area Tb1 is red.

When the transmission of the monitor image P11 including the detailed image is controlled in Act173, the processor 21 disregards the timer interrupt in Act 176. For example, in response to detecting that the layout button BU14 for monitoring images has been touched, the processor 21 returns to the process of Act 161.

Fig. 36 is an example of a monitoring image P11 when the terminal state display section Tb indicating the "set" state has been touch-operated. As shown in fig. 36, monitor image P11 includes a touch-operated state display unit Tb, and a touch button BU17 for displaying detailed images P111 of the product names, the number of items, the amount of money, and the like of the commodities registered in information terminal 50 of the state in state on state display unit Tb. When the terminal state display unit Tb indicating the "registration in progress" state has been touch-operated, the detailed screen P111 is displayed, but the touch button BU17 of "all around cancel" is not displayed.

As described above, the information terminal 50 whose terminal state ST1 is managed as "put" cannot be used unless the information of the information terminal table 221 is initialized. The server M3 touches and operates the terminal state display section Tb shown in fig. 35(E) if the terminal state display section Tb is found. When the terminal state display section Tb is touch-operated, the monitoring image P11 of fig. 36 is displayed. The attendant M3 touches and operates the "all around cancel" touch button BU 17.

The processor 61 of the monitoring terminal 60, when detecting that the touch button BU17 of "summary cancellation" has been touched, controls the wireless unit 64 so as to send a summary cancellation instruction to the second server 20. The wireless unit 64 wirelessly transmits the aggregate cancellation instruction. The collective cancellation instruction includes the terminal ID of the information terminal 50 assigned to the touch-operated terminal state display section Tb. The summary cancellation instruction is received by the access point 80 and sent to the second server 20 via the network 70.

The processor 21 of the second server 20 that has received the all-inclusive cancellation instruction through the communication interface 24 starts the all-inclusive cancellation interrupt processing shown in the flowchart of fig. 27. First, the processor 21 detects a terminal ID from the total cancellation instruction as Act 181. The processor 21 searches the information terminal table 221 as Act182, and searches for the terminal status ST1 associated with the terminal ID detected from the all-round cancel instruction. In the following description, the terminal ID detected from the collective cancellation command is referred to as a cancellation terminal ID. When the terminal state ST1 is not "put", the processor 21 proceeds to NO in Act 182. The processor 21 ends the all-together cancel interrupt processing.

When the terminal state ST1 is "put", the processor 21 proceeds to YES in Act 182. The processor 21 confirms as Act183 whether or not the third timer T3 associated with the cancel terminal ID of the information terminal table 221 has elapsed the second threshold time TM2, which is long compared to the first threshold time TM1, such as 15 minutes. When the third timer T3 passes the second threshold time TM2, the processor 21 proceeds to YES in Act 183. The processor 21 proceeds to the processing of Act 186.

When the third timer T3 does not reach the second threshold time TM2, the processor 21 proceeds to NO in Act 183. The processor 21 controls the communication interface 24 to cause the image data of the cancellation confirmation image P12 shown in fig. 37 to be transmitted to the monitoring terminal 60. The communication interface 24 transmits the image data of the cancellation confirmation image P12 through the network 70. The access point 80 wirelessly transmits the image data. The monitoring terminal 60 receives image data wirelessly transmitted from the access point 80. The monitor terminal 60 displays a cancellation confirmation image P12 on the touch panel 65.

Fig. 37 is a diagram showing an example of display of the cancellation confirmation image P12. As shown in fig. 37, the cancellation confirmation image P12 includes a guide GA3 asking whether to perform the total cancellation, and further includes a "go" touch button BU21 and a "not go" touch button BU 22. The serviceman M3 who confirmed the cancellation confirmation image P12 confirms again whether or not the total cancellation is permitted. When the total-sum cancellation is permitted, the attendant M3 touches the operation touch button BU 21. When the total bracket cancellation is suspended, the attendant M3 touches the operation touch button BU 22.

The processor 21 which has controlled the image data transmission of the cancellation confirmation image P12 waits for the acceptance of the instruction input of whether or not the all-round cancellation can be made as Act 185. When detecting that the touch button BU22 of "not done" of the cancellation confirmation image P12 has been touch-operated, the processor 21 proceeds to NO in Act 185. The processor 21 ends the all-together cancel interrupt processing.

When detecting that the touch button BU22 of "go" of the cancellation confirmation image P12 has been touch-operated, the processor 21 proceeds to YES in Act 185. The processor 21 proceeds to the processing of Act 186.

In Act186, the processor 21 initializes the information associated with the cancel terminal ID of the information terminal table 221. That is, the processor 21 clears the member ID of the area A3, the check-out ID of the area a4, the registration list L1 of the area a9, the promotion list L2 of the area a10, the shopping list L3 of the area a11, and the check-out code of the area a 12. The processor 21 resets the values of the first timer T1 of the region a5, the second timer T2 of the region a6, and the third timer T3 of the region a9 to "0". Also, the processor 21 resets the value of the counter N of the area A8 to "0".

After that, the processor 21 changes the state ST1 associated with the cancel terminal ID of the information terminal table 221 from "put" to "standby" as Act 187. In the above, the processor 21 ends the collective cancellation interrupt processing.

When the all-round cancel interrupt process is executed, the data of the information terminal table 221 relating to the information terminal 50 whose terminal state ST1 is "put" is initialized. The information terminal 50 in which the data of the information terminal table 221 has been initialized can be used as a terminal for self-service registration.

As described above in detail, according to the present embodiment, the second server 20 describes the information of the purchased product registered in the information terminal 50 in the information terminal table 221 as the registration list L1 in the main memory 22 for each information terminal. The second server 20 describes the promotion information associated with each purchased product in the information terminal table 221 as a promotion list L2 in the main memory 22 for each information terminal. The second server 20 arranges the latest plural images such as four images among the images of the promotion information on the purchased articles registered by the information terminal 50 in the promotion list area PA2 of the registration image P1. The information terminal 50 receives the registration image P1 from the second server 20 and displays it in the touch panel 55. The touch panel 55 of the information terminal 50 displays the registration image P1, thereby presenting the customer M1 with a plurality of pieces of sales promotion information including the latest sales promotion information. Such display of the registration image P1 is effective for further improving the sales promotion effect for the customer M1.

According to the present embodiment, the second server 20 arranges the latest promotion information in the promotion list area PA2 in the registration image P1. Here, the second server 20 arranges the latest promotion information in the promotion area PA21 at the left end among the promotion list areas PA2 in the registration image P1. The second server 20 changes the latest sales promotion information to an image visually different from other sales promotion information so that the latest sales promotion information can be recognized as information related to the latest purchased product. The information terminal 50 receives the registration image P1 from the second server 20 and displays it on the touch panel 55. The customer M1 views the registration image P1 displayed on the touch panel 55 of the information terminal 50. The customer M1 can easily recognize which of the plurality of pieces of promotional information is the promotional information related to the purchased product that has just been registered by viewing the registration image P1. That is, the customer M1 who has just registered an interest in purchasing the item facilitates identification of the associated promotional information.

According to the present embodiment, the second server 20 also generates, in the registration image P1, an image in which the purchased article just registered is arranged uppermost with respect to the registration list area PA1 displaying a list of purchased articles. The second server 20 makes it into an image that can recognize the purchased article just registered. The information terminal 50 receives the registration image P1 from the second server 20 and displays it in the touch panel 55. According to the display of the registration image P1 of the touch panel 55 of the information terminal 50, the customer M1 can easily recognize the relationship between the purchased article and the sales promotion information.

According to the present embodiment, the second server 20 shifts the coincidence promotion information to the newest description order in the promotion list L2 when the promotion information has been described in the promotion list L2. The promotion list area PA2 in the registration image P1 does not repeat images containing the same promotion information. The limited promotion list area PA2 can be effectively utilized.

According to the present embodiment, the second server 20 does not perform the inquiry of the promotion information to the first server 10 when the link information of the purchased article has been registered in the promotion list L2. This configuration does not waste limited communication resources, and therefore, power consumption of the communication interface 24 can be suppressed.

Second embodiment

The first embodiment described above displays the promotion information using the registration of the article as a trigger. In the present embodiment, the display of the promotion information is changed by another trigger.

The configuration of the product sales system according to the second embodiment may be the same as the configuration of the product sales system according to the first embodiment.

The operation is as follows.

Fig. 38 is a flowchart showing a part of the procedure of extracting main information processing executed by the processor 51 of the information terminal 50 in the product sales system according to the present embodiment. In the present embodiment, the processor 51 proceeds to NO when NO commodity registration is performed in Act6 described above. The processor 51 checks whether any one of the commodities is touched from the list of purchased commodities displayed in the registration list area PA1 of the registration image P1, that is, whether a selection operation of the commodity is performed. When the selection operation of the article is not performed, the processor 51 proceeds to NO in Act 191. The processor 51 confirms as Act192 whether or not the touch button BU3 of "cancel" has been touched, that is, whether or not a cancel operation of the merchandise item has been performed. When the cancellation operation of the article is not performed, the processor 51 proceeds to NO in Act 192. The processor 51 confirms as the above Act7 whether or not the touch button BU2 of "checkout" has been touched. The processor 51 touches a touch button BU2 of Act6, Act191, Act192, and Act7, which waits for acceptance of the fact that the commodity registration is performed, the commodity selection operation is performed, the commodity cancellation operation is performed, or "checkout".

When it is confirmed that the article selection operation has been performed in the wait-for-acceptance state of Act6, Act191, Act192, and Act7, the processor 51 proceeds to YES in Act 191. The processor 51 controls the wireless unit 54 as Act193 so as to transmit the goods selection instruction to the second server 20. The wireless unit 51 wirelessly transmits the article selection instruction. The product selection command includes the terminal ID of the information terminal 50 and the product ID of the selected product. The access point 80 receives the article selection instruction and transmits it to the second server 20 through the network 70.

The processor 21 of the second server 20, which has received the commodity selection instruction through the communication interface 24, starts the commodity selection interrupt process shown in the flowchart of fig. 39.

The processor 21 detects the product ID from the product selection instruction as Act 201. The processor 21 retrieves, as the Act202, the promotion list L2 of the area a10 associated with the registered terminal ID of the information terminal table 221. The processor 21 proceeds to NO as Act203 when NO promotion data associated with a conforming item ID is registered in the promotion list L2. The processor 21 ends the commodity selection interrupt process.

When the promotion data associated with the conforming item ID is registered in the promotion list L2, the processor 21 proceeds to YES in Act 203. The processor 21, as Act204, shifts the conforming item ID, promotion ID and promotion data to the same numbered region as counter N. The processor 21 changes the value of the fourth flag F4 of the area of the promotion list L2 numbered identically to the counter N to "1" and the value of the fourth flag F4 of the other numbered area to "0" as the Act 205.

The processor 21 creates a promotion image as the Act206 from the promotion list L2 of the area a10 associated with the registered terminal ID of the information terminal table 221. In Act207, the processor 21 compiles a promotion list area PA2 in the registration image P1.

The processor 21 controls the communication interface 24 as Act208 to transmit the registration image P1 to the information terminal 50 of the commodity registration instruction transmission source. The communication interface 24 transmits the image data of the registration image P1 compiled in Act207 through the network 70. The access point 80 wirelessly transmits the image data. The information terminal 50 of the product registration instruction transmission source receives the image data wirelessly transmitted from the access point 80.

The explanation returns to fig. 38.

The processor 51 of the information terminal 50 that has controlled the transmission of the commodity selection instruction at Act193 returns to Act5 described above. That is, the processor 51 updates the registration image P1 displayed on the touch panel 55 based on the image data newly received from the second server 50.

By updating the registration image P1, the display on the touch panel 51 of the information terminal 50 transitions as follows. When promotion information is set in association with an article that the customer M1 has selected from the registration list area PA1, the information terminal 50 displays a promotion image based on the promotion information in the promotion area PA21 of the promotion list area PA 2. At this time, when other pieces of promotion information have been displayed in the promotion areas PA21 to PA23, these pieces of other pieces of promotion information are shifted in order toward the promotion areas PA22 to PA24 on the right side. The promotion information originally displayed in the promotion area PA24 becomes undisplayed. When the promotion information of the selected merchandise has been displayed in the promotion area PA21, the promotion image of the promotion list area PA2 is not changed. When promotional information for a selected item is displayed, such as in promotional area PA22, the promotional information is moved to promotional area PA21, and the promotional information that was previously displayed in sales area PA22 is shifted to promotional area PA 22. The same is true when promotion information of the selected merchandise is displayed in the other promotion areas PA23, PA 24.

The processor 51 proceeds to YES in Act191 every time a product selection is made. The processor 51 repeats the processing of Act193 and Act 5.

When it is confirmed that the product canceling operation has been performed in the wait-to-accept state of Act6, Act191, Act192, and Act7 described above, the processor 51 proceeds to YES in Act 192. The processor 51 controls the wireless unit 54 as Act194 so as to transmit the article cancellation instruction to the second server 20. The wireless unit 54 wirelessly transmits the article cancellation instruction. The article cancellation instruction contains the terminal ID of the information terminal 50, and the article ID of the article that the touch button BU3 of "cancel" has been touched. The access point 80 receives the article canceling instruction and transmits it to the second server 20 via the network 70.

The processor 21 of the second server 20 that has received the commodity cancel instruction through the communication interface 24 starts the commodity cancel interrupt processing shown in the flowchart of fig. 40.

The processor 21 detects the article ID from the article cancel instruction as Act 211. The processor 21 changes the number of matching article IDs and the amount of money in the registration list L1 of the area a9 associated with the registered terminal ID of the information terminal table 221 to "0" as Act 212.

The processor 21 retrieves the promotion list L2 of the area a10 associated with the registered terminal ID of the information terminal table 221 as Act 213. The processor 21 proceeds to NO as Act214 when NO promotion data associated with a conforming item ID is registered in the promotion list L2. The processor 21 ends the commodity cancel interrupt processing.

When the promotion data associated with the conforming item ID is registered in the promotion list L2, the processor 21 proceeds to YES in Act 214. Processor 21 deletes the conforming item ID, the promotion ID, and the promotion data as Act 215. The processor 21 decrements the value of the counter N of the area A8 associated with the registered terminal ID of the information terminal table 221 by "1" as Act 216.

In Act217, processor 21 confirms whether the value of counter N counts a value larger than "0". When the value of the counter N is "0", the processor 21 proceeds to NO in Act 217. Processor 21 proceeds to Act 220.

When the value of the counter N is large as compared with "0", the processor 21 proceeds to YES in Act 217. The processor 21 changes the value of the fourth flag F4 of the area of the promotion list L2 numbered identically to the counter N to "1" and the value of the fourth flag F4 of the other numbered area to "0" as Act 218.

The processor 21 creates a promotion image from the promotion list L2 of the area a10 associated with the registered terminal ID of the information terminal table 221 as Act 219. In Act220, the processor 21 compiles a promotion list area PA2 in the registration image P1.

The processor 21 controls the communication interface 24 as Act221 to cause the registration image P1 to be transmitted to the information terminal 50 of the commodity cancellation instruction transmission source. The communication interface 24 transmits the image data of the registration image P1 compiled in Act220 through the network 70. The access point 80 wirelessly transmits the image data, and the information terminal 50 of the product cancellation instruction transmission source receives the image data.

The explanation returns to fig. 38.

The processor 51 of the information terminal 50 that has controlled the transmission of the commodity cancellation instruction in Act194 returns to Act5 described above. That is, the processor 51 updates the registration image P1 displayed on the touch panel 55 based on the image data newly received from the second server 20.

By updating the registration image P1, the display on the touch panel 51 of the information terminal 50 transitions as follows. When the customer M1 touches the "cancel" touch button BU3 of the registration list area PA1, the sales promotion area PA21 of the sales promotion list area PA2 does not display a sales promotion image based on the sales promotion information when the sales promotion information is set in association with the product when the product is cancelled. At this time, when the promotion information has been displayed in any one of the promotion areas PA21 to PA24, the display is canceled, and the promotion information displayed in the promotion area on the right side thereof is shifted to the left side in order. The promotion area PA24 displays promotion information associated with the first five (the first fifth) registered commodities displayed shifted to the right from the promotion list area PA2 and deleted. When the promotion information of the cancelled commodity is not displayed in the promotion list area PA2, the image of the promotion list area PA2 is not changed.

The processor 51 proceeds to YES in Act192 every time article cancellation is performed. The processor 51 repeats the processing of Act194 and Act 5.

As described in detail above, according to the present embodiment, when the customer M1 selects a purchase item from the registration list area PA1 through the touch panel 55 of the information terminal 50, the second server 20 arranges an image of the promotion information related to the agreement with the purchase item in the promotion area PA21 for the latest promotion information of the promotion list area PA 2. The information terminal 50 that received the registration image P1 from the second server 20 displays the registration image P1 on the touch panel 55, in which the image of the sales promotion information related to the purchased products is included in the sales promotion area PA 21. In this way, by switching and displaying the sales promotion information related to the past registered merchandise, the customer M1 can view the sales promotion information that is overlooked during shopping or that is desired to be confirmed again. Since the sales promotion information intended by the customer M1 can be presented again, a sales effect can be expected.

Further, according to the present embodiment, when cancellation of purchase of an article is made, the second server 20 deletes the image of the promotion information associated with the article it cancels from the promotion list area PA2 or is not included in the promotion list area PA 2. By doing so, since the promotion information on the article which the customer M1 does not have an interest in is not presented, the limited promotion list area PA2 is not wasted.

Third embodiment

As the sales promotion information, there are coupons and the like that can be used next time the store comes. The product sales system according to the third embodiment displays the sales promotion information to be displayed next time when the customer M1 who is a member registers next time in the sales promotion list area PA2, not at the time of product registration.

The configuration of the product sales system according to the third embodiment may be basically the same as the configuration of the product sales system according to the first embodiment except for the following description.

Fig. 41 is a diagram showing a main data structure of the promotion data record 133R held in the promotion database 133 of the first server 10 in the merchandise sales system according to the present embodiment. In the present embodiment, the promotion data record 133R includes not only the promotion ID and the promotion data but also the display timing data. The display timing data shows that the sales promotion information is displayed at any time of the registration of the article and the next registration. For example, the display timing data is set to "0" as one-bit (bit) data when the sales promotion information is displayed at the time of registration of the product, and is set to "1" when the sales promotion information is displayed at the time of the next registration.

Fig. 42 is a schematic diagram showing the configuration of the information terminal table 221 provided in the main memory 22 of the second server 20. The information terminal table 221 in the present embodiment has an area a14 for describing information of the purchase history list, in addition to the configuration of the information terminal table 221 in the first embodiment.

Fig. 43 is a schematic diagram showing an example of the purchase history list L4 described in the area a 14. The purchase history list L4 describes at least the product ID in a series of numbers.

Next, the operation of the present embodiment will be described.

Fig. 44 is a flowchart showing a part of the procedure of extracting the login interruption process executed by the processor 21 of the second server 20.

After changing all the fifth flags F2 corresponding to the respective numbers of the shopping list L3 to "0" as the above Act28, the processor 21 determines as Act231 whether or not there is purchase history data in the approval response from the first server 10 in the present embodiment.

In the present embodiment, the processor 11 of the first server 10, in response to the authentication inquiry of the member ID, includes the purchase history data in the approval response when the purchase history data is stored in the member data record 132R of the member database 132 specified by the member ID. The purchase history data contains at least an article ID. The purchase history data included in the approval reply may be all of the purchase history data stored in the member data record 132R. From the viewpoint of the amount of communication, the storage capacity in the second server 20, it is desirable that the purchase history data included in the approval response sets some limit. For example, the purchase history data contained in the approval reply can be considered to be data from the new purchase history data to several days ago. For example, the purchase history data included in the approval response can be regarded as data corresponding to the second server 20 that has made the authentication query. For example, the purchase history data included in the approval response can be regarded as data from the new purchase history data to several days ago among the data corresponding to the second server 20 that has performed the authentication query.

When the registered customer M1 purchased a product in advance, the approval response includes purchase history data. When no goods are purchased, the approval reply does not contain purchase history data. When the approval reply does not contain purchase history data, the processor 21 proceeds to NO in Act 231. The processor 21 proceeds to the processing of Act 28.

When the approval response contains the shopping data, processor 21 proceeds to YES in Act 231. The processor 21 composes a purchase history list L4 from the purchase history data as Act 232. That is, the processor 21 adds a series of numbers to the product ID constituting the purchase history data, and creates the purchase history list L4. The processor 21 holds a purchase history list L4 in the area a14 associated with the login terminal ID of the information terminal table 221.

The processor 21 controls the communication interface 24 as Act233 to make the inquiry of the promotion data to the first server 10. The communication interface 24 sends a promotional data query. The promotion data query instruction contains the article ID contained in the purchase history list L4 stored in the Act232 described above. The promotional data query instruction is sent to the first server 10 via the network 70.

The processor 11 of the first server 10 which receives the promotion data query instruction through the communication interface 14 detects the article ID from the promotion data query instruction. The processor 11 accesses the product database 131, and reads out the product data record 131R including the product ID. The processor 11 accesses the promotion database 133 by the linked promotion ID included in the product data record 131R, and reads out the promotion data record 133R including the promotion ID corresponding to the linked promotion ID. When the promotion data record 133R conforming to the promotion ID is not registered in the promotion database 133, the processor 11 controls the communication interface 14 so that a normal response without promotion is transmitted to the second server 20. The communication interface 14 sends a normal response to the second server 20 without promotion.

The processor 11, when the conforming promotion data record 133R can be read out from the promotion database 133, confirms the display timing data of the conforming promotion data record 133R. When the value of the display period data is "0", the same is true when the promotion data record 133R conforming to the promotion ID is not registered in the promotion database 133. The processor 11 controls the communication interface 14 so that a normal response without promotion is sent to the second server 20. The communication interface 14 sends a normal response to the second server 20 without promotion.

When the value of the display period data in conformity with the promotion data record 133R is "1", the processor 11 controls the communication interface 14 so that a normal response containing the promotion data is transmitted to the second server 20. The communication interface 14 sends a normal response containing the promotion data to the second server 20.

The processor 21 of the second server 20 that controls the transmission of the promotion inquiry instruction confirms as Act234 whether a normal response containing the promotion data is received. When a normal response without promotion is received, the processor 21 proceeds to NO in Act 234. The processor 21 proceeds to the processing of Act 29.

When a normal answer containing promotional data is received, the processor 21 proceeds to YES in Act 234. The processor 21 adds "1" to the value of the counter N of the area A8 associated with the registered terminal ID of the information terminal table 221 as Act 235. The processor 21 adds data as Act236 to the promotion list L2 of the area a10 associated with the registered terminal ID in the information terminal table 221. The data includes the article ID of the purchased article, the link promotion ID associated with the article ID, and promotion data in which the link promotion ID is set. The processor 21 appends the data to the same numbered zone as the value of the counter N.

The processor 21, as Act237, changes the value of the fourth flag F4 of the area numbered identically to the value of the counter N of the promotion list L2 to "1", and changes the value of the fourth flag F4 of the other numbered area to "0". The processor 21 composes a promotion image from the promotion list L2 of the area A10 associated with the registered terminal ID of the information terminal table 221 as Act 238. The processor 21 proceeds to Act29 when it is finished composing the promotional image. Thereafter, as described in the above-described first embodiment, the processor 21 generates a registration image, and transmits the registration image to the information terminal 50 of the registration instruction transmission source.

When a plurality of product IDs are included in the purchase history list L4 stored in the Act232, the processor 21 sequentially repeats the processing from the Act233 for each product ID.

Through such processing, the information terminal 50 of the registration instruction transmission source can present the sales promotion information set so as to be displayed at the time of registration to the customer M1.

When there is a promotion inquiry command from the second server 20 at the time of product registration, the processor 11 of the first server 10 reads out the promotion data record 133R from the promotion database 133 by the linked promotion ID contained in the promotion inquiry command. When the promotion data record 133R of the promotion ID is not registered in the promotion database 133 and when the value of the registration display period data is made "1", the processor 11 controls the communication interface 14 so that a normal response without promotion is transmitted to the second server 20. The communication interface 14 sends a normal response to the second server 20 without promotion.

The processor 11 controls the communication interface 14 so that a normal response containing the promotion data is transmitted to the second server 20 when the matching promotion data record 133R can be read out from the promotion database 133 and the value of the display period data is "0". The communication interface 14 sends a normal response containing the promotion data to the second server 20.

In this way, the information terminal 50 can present the customer M1 with the sales promotion information set so as to be displayed at the time of registration of the product.

As described above in detail, according to the present embodiment, since the second server 20 confirms the purchase history of the customer M1 at the time of login of the customer M1 and arranges the image of the promotion information in the promotion list area PA2 based on the purchase history, the promotion information to be displayed next time the customer M1 comes to the store can be presented, which is advantageous for promotion.

The number of digits of the display timing data of the promotion data record 133R stored in the promotion database 133 of the first server 10 may be further increased, and the promotion information may be displayed not only at the time of registration of the product and at the time of the next registration, but also at both the time of registration of the product and at the time of the next registration. For example, the value of the display timing data is "01" when the sales promotion information is displayed at the time of commodity registration, "10" when displayed at the time of next registration, and "11" when displayed at both the time of commodity registration and the time of next registration. Such as "at login", "at commodity registration", "at checkout completion", "at next login", "at next commodity registration", "at next checkout completion", etc., it is possible to design the display timing data so that the values thereof are appropriately assigned. Not only the individual products but also the specific department/team, the total amount, and the like may be attributes of the sales promotion information to be presented.

The display time data may include a relative validity period such as a time of several days from the purchase date. The display time data need not include an absolute validity period of which month and which day, etc. This is because, when the absolute expiration date has passed, the promotion data record 133R is deleted or the display timing data of the promotion data record 133R is rewritten.

Although the above description has been given of the embodiment of the terminal management device that can perform effective display for further improving the sales promotion effect in the information terminal, the embodiment is not limited to this.

For example, the registration screen displayed on the touch panel 55 of the information terminal 50 in the product sales system may be a registration image P5 as shown in fig. 45. The registration image P5 includes a registration list area PA1 in which a registered product area PA5 replaces the registration image P1. The registered commodity region PA5 displays information on the latest registered commodity. The registration image P5 further includes a touch button BU23 of "barcode scanner" and a touch button BU24 of "shopping basket" with respect to the registration image P1. The touch button BU23 of the "barcode scanner" is a button that is touched when commodity registration is performed using the scanner 56. The touch button BU24 of "shopping basket" includes an image indicating that it is a shopping basket, and also includes an image indicating the total amount and an image indicating the number of registered commodities. When the touch button BU24 of this "shopping basket" is touched, a list of registered commodities is displayed. By touching the touch button BU24 of the "shopping basket", the registration image P5 can be switched to the registration image P1 as shown in fig. 28.

In the above-described embodiment, the commodity data newly added to the registration list L1 is recognizable such as making the color of characters different from that of other commodity data or making the color of the background different. The commodity data may also be displayed for identification with an action, such as a blinking display or a display that causes a frame to emit light. By doing so, the discrimination of the product data can be further improved. In this manner, the customer M1 is further prompted to touch the promotional information being associated.

The second server 20 may display the updated detailed promotion information to the information terminal 50 in response to the customer M1 touching the promotion information. Such an operation is usually performed, and a detailed description thereof is omitted here.

The second server 20 may slide the touch panel 55 by the customer M1 to display past sales promotion information not displayed in the sales promotion list area PA2 on the information terminal 50.

In the above embodiments. The case where the information terminal 50 is provided on the cart C is exemplified. In this regard, the information terminal 50 is not necessarily provided on the cart C. A customer may also shop by physically carrying the information terminal 50 and properly operating the information terminal 50 to register a purchased article.

The transfer of the second server 20 is generally performed in a state where the program is stored in the ROM. However, the program is not limited to this, and may be transferred in a state where the program is not stored in the ROM. In this case, a program or the like assigned separately from the second server 20 may be written in a writable storage device included in the second server 20 in accordance with an operation by a user or the like. The transfer of the program and the like can be recorded in a removable storage medium or performed by communication through the network 70. The form of the storage medium is not limited as long as the storage medium can store a program and the device can read it, such as a CD-ROM, a memory card, or the like.

Furthermore, while several embodiments of the invention have been described, these embodiments have been presented by way of example and are not intended to limit the scope of the invention. These novel embodiments may be embodied in other various forms, and various omissions, substitutions, and changes may be made without departing from the spirit of the invention. These embodiments and modifications are included in the scope and gist of the invention, and are included in the invention described in the scope of claims and the equivalent scope thereof.

In the present invention, there is provided an electronic device including: at least one processor; and a memory communicatively coupled to the at least one processor, wherein the memory stores instructions executable by the at least one processor to enable the at least one processor to perform the control method described above.

Further, in the present invention, there is provided a non-transitory computer-readable storage medium storing computer instructions for causing a computer to execute the above-described control method.
