Hereinafter, a server apparatus and the like according to the present invention will be described using embodiments. In the following embodiments, constituent elements and steps with the same reference numerals are the same or correspond to each other, and repetitive description may be omitted. The server device according to the present embodiment provides users with detailed information on products posted on leaflets on paper media.

FIG. 1 is a schematic diagram showing the configuration of an information communication system according to this embodiment, and FIG. 2A is a block diagram showing the configuration of a server device 1 according to this embodiment. The information communication system includes a server device 1 , a plurality of user terminal devices 2 and a store terminal device 3 . Note that the information communication system may include a plurality of store terminal devices 3 . The server device 1, the user terminal device 2, and the store terminal device 3 are connected by a wired or wireless communication line 500. FIG. The communication line 500 may be, for example, the Internet, an intranet, a public telephone line network, or the like. The communication line for communication between the server device 1 and the user terminal device 2 and the communication line for communication between the server device 1 and the store terminal device 3 may be the same or different. may The user terminal device 2 is a terminal used by a user who sees a leaflet on a paper medium, and may be, for example, a smart phone, a tablet terminal, a personal computer, or the like. The user terminal device 2 is usually preferably a portable terminal, but this need not be the case. The user terminal device 2 may be a desktop personal computer or the like. The store terminal device 3 is a terminal used by an employee or the like of a store that sells products posted on leaflets. The store terminal device 3 may or may not be a portable terminal.

As shown in FIG. 2A, the server device 1 includes a storage unit 11, a reception unit 12, a specification unit 13, a transmission unit 14, an accumulation unit 15, an analysis unit 16, a creation unit 17, a purchase plan An acquisition unit 18 and an unpurchased product acquisition unit 19 are provided.

The storage unit 11 stores one or more item correspondence information. Product-related information consists of a code identifier that identifies the code displayed on a paper-based leaflet listing multiple products sold at a store, a product identifier that identifies the product listed on the leaflet, and a product identifier. This is information that associates a plurality of product information including detailed product information, which is detailed information.

Paper media flyers can be independent flyers, such as newspaper inserts, or attached to other media, such as advertisements displayed in paper media such as newspapers and magazines. It may be a leaflet. In the latter case, a part of a newspaper page, a part of a page or a part of a page of a magazine may serve as a leaflet. Strictly speaking, the fact that a product is posted on a leaflet may mean that information about the product, such as the name, photo, and price of the product, is posted on the leaflet.

The product may be, for example, food, daily necessities, home appliances, or other products. Merchandise is typically merchandise that is sold at a store. In this embodiment, a description will be given mainly of the case where the product is food. The product identifier may be, for example, the name of the product, a symbol or character string (for example, JAN code, EAN code, etc.) for identifying the product, or other information that can identify the product. may be Also, the product identifier may be appropriately replaced during the process, for example. Specifically, the product identifier included in the product correspondence information is a JAN code, and when the product identifier is transmitted to the user terminal device 2, the JAN code may be converted into a product name and transmitted. In this case, the storage unit 11 stores information that associates the product identifier, which is the JAN code, with the product identifier, which is the product name, and the product identifier may be appropriately replaced using this information.

The code displayed on the leaflet may be, for example, a one-dimensional code such as a barcode, a two-dimensional code such as a QR code (registered trademark), or any other code. In this embodiment, a case where the code is a QR code will be mainly described. The code identifier may be, for example, information indicated by the code, i.e. information obtained by reading the code, may be part of that information, or may be other information that can identify the code. may The information indicated by the code is a URL (Uniform Resource Locator), the domain portion of the URL indicates the address of the server device 1, and the portion related to the directory structure (path name portion) other than the domain portion indicates the code identifier. may In this embodiment, this case will be mainly described. In the user terminal device 2, the URL corresponding to the code displayed on the leaflet is acquired and the server device 1 is accessed, so that the processing in the user terminal device 2 can be executed by, for example, a web application. Become. Therefore, in the user terminal device 2, the process of accessing the server device 1 and obtaining detailed product information, for example, may be executed by a web application or by a native application. When the information indicated by the code is the code identifier, the user terminal device 2 normally accesses the server device 1 whose address and the like are set in advance by the native application.

The detailed product information is product information that is more detailed than the product information posted on the leaflet. Note that the detailed product information may include, for example, information posted on a leaflet. The detailed product information may be, for example, information on the calorific value, nutrients, and allergens of the product, which is food. Further, the detailed product information may be, for example, information indicating specifications of a product that is a home appliance.

Moreover, the product information may include information other than the above. For example, product image data may be included. Further, in the product correspondence information, the code identifier may be associated with the period of the leaflet in which the code identified by the code identifier is displayed. In this case, the product list and detailed product information using the product-related information may be transmitted only during that period.

The storage unit 11 stores one or more pieces of user shopping memo information. The user shopping memo information is information that associates a user identifier with a shopping memo of the user identified by the user identifier. The user identifier may be, for example, the name of the user, an address or telephone number that can identify the user, or a symbol or character string that identifies the user. A shopping memo is a list of product identifiers that identify products to be purchased. The shopping memo includes product identifiers of products that the user wishes to purchase. Note that the shopping memo does not contain the product identifier until the user adds the product identifier to the shopping memo. The shopping memo may also include, for example, the number of products identified by the product identifier. Further, for example, when a shopping memo is created from a plurality of leaflets, a code identifier may be associated with a product identifier in the shopping memo so that the shopping memo can be distinguished for each leaflet. In this embodiment, in order to simplify the explanation, the case where the shopping memo contains only the product identifier will be mainly explained.

The process by which information is stored in the storage unit 11 does not matter. For example, information may be stored in the storage unit 11 via a recording medium, information transmitted through a communication line or the like may be stored in the storage unit 11, or Information input via an input device may be stored in the storage unit 11 . As will be described later, the product identifier of the shopping memo included in the user shopping memo information is accumulated by the creation unit 17 . Information other than the above may be stored in the storage unit 11 . The storage unit 11 is preferably implemented by a non-volatile recording medium, but may be implemented by a volatile recording medium. The recording medium may be, for example, a semiconductor memory, a magnetic disk, an optical disk, or the like.

The receiving unit 12 receives, from the user terminal device 2, a code identifier that identifies the code displayed on the leaflet. The code identifier may be obtained from an image of the code displayed on the leaflet that has been photographed. The receiving unit 12 also receives, from the user terminal device 2, a detailed product information transmission request, which is transmitted by the transmitting unit 14 and requests transmission of detailed product information corresponding to a product identifier included in a product list, which will be described later. The product detail information transmission request may include a product identifier that identifies the product for which transmission is requested. The product detail information transmission request may also include, for example, a code identifier. For example, if a product is uniquely identified by a code identifier and a product identifier, it is preferable that the product detail information transmission request also include the code identifier.

Also, the receiving unit 12 may receive a user identifier that identifies a user. The receiving unit 12 may also receive a product identifier to be added to the shopping memo. The receiving unit 12 may receive a request to add the product identifier to the shopping memo together with the product identifier. The receiving unit 12 may also receive a shopping memo transmission request requesting transmission of a shopping memo. Note that the product identifier and shopping memo transmission request can specify the shopping memo to which the product identifier is to be added and the shopping memo for which transmission is requested, so that the corresponding user identifier can be specified. Preferably received. Therefore, for example, the product identifier and shopping memo transmission request may be received at the same time as the user identifier, or may be received while the user is logged in.

The receiving unit 12 may receive, from the store terminal device 3, purchased product information including the user identifier and the product identifier of the product purchased by the user identified by the user identifier. This purchased product information is, for example, the user identifier presented by the user when the user purchases the product at the cash register of the store, and the product acquired using the barcode read from the product in the purchase procedure of the product. It may be information including an identifier. From this purchased product information, it is possible to know which product the user has purchased. The purchased product information received may be accumulated in the storage unit 11 .

Note that the receiving unit 12 may or may not include a wired or wireless receiving device (eg, modem, network card, etc.) for receiving. Further, the receiving unit 12 may be realized by hardware, or may be realized by software such as a driver for driving the receiving device.

When the code identifier is received by the receiving unit 12, the specifying unit 13 specifies a plurality of product identifiers associated with the received code identifier by the product correspondence information. The specifying unit 13 may, for example, search the product-related information using the received code identifier as a search key, and specify all product identifiers associated with hit code identifiers. The product identifier may be specified, for example, by storing the product identifier to be specified in a recording medium (not shown), or by adding information such as a flag to the product identifier to indicate that it has been specified. may be broken.

The transmitting unit 14 transmits the product list including the product identifier specified by the specifying unit 13 to the user terminal device 2 . The user terminal device 2 that is the transmission destination of the product list may be, for example, the user terminal device 2 that is the transmission source of the code identifier. The product list may be information including product identifiers, or product identifiers and information for displaying the product identifiers on the user terminal device 2 (for example, information written in a markup language such as HTML). and may be information including. The same may be true when other information is transmitted to the user terminal device 2 . Further, the product list may include, for example, image data of the product together with the product identifier.

When the code identifier is received by the receiving unit 12, the transmitting unit 14 may transmit to the user terminal device 2 viewing information indicating that the leaflet displaying the code identified by the code identifier has been viewed. good. It is preferable that when the viewing information is output from the user terminal device 2, it is possible to know which handbill has been viewed. Therefore, the browsing information may include, for example, information that can identify the leaflet on which the code identified by the received code identifier is displayed. The information that can identify the leaflet may be, for example, the code identifier of the code displayed on the leaflet, the name of the store corresponding to the leaflet, and the advertisement period of the leaflet, and the leaflet can be identified. Other information may be used. A code identifier included in the browsing information may be image data of a code indicating the code identifier. The browsing information may be, for example, coupons or discount coupons. This viewing information may be acquired by the transmitting unit 14, for example. The viewing information may be transmitted, for example, when the code identifier is received, or may be transmitted when the viewing information transmission request is received from the user terminal device 2 after the code identifier is received. In the latter case, the receiving unit 12 may also receive a transmission request for viewing information. The browsing information may be, for example, information displayed on the user terminal device 2, or may be information transmitted by wireless communication such as short-range wireless communication.

When the receiving unit 12 receives the detailed product information transmission request, the transmitting unit 14 transmits to the user terminal device 2 the detailed product information requested to be transmitted by the detailed product information transmission request. For example, when the product detail information transmission request includes the product identifier of the product for which transmission is requested, the transmission unit 14 uses the product correspondence information to identify the product detail information corresponding to the product identifier, The specified product detailed information may be transmitted to the user terminal device 2 . When a code identifier is also included in the detailed product information transmission request, the transmission unit 14 may specify the detailed product information using the code identifier and the product identifier. The user terminal device 2 that is the transmission destination of the detailed product information may be, for example, the user terminal device 2 that is the transmission source of the detailed product information transmission request.

When the receiving unit 12 receives the user identifier and the shopping memo transmission request, the transmitting unit 14 may transmit the shopping memo corresponding to the user identifier to the user terminal device 2 . A shopping memo corresponding to a user identifier may be a shopping memo associated with the user identifier by user shopping memo information. A sent shopping memo usually contains a product identifier. The user terminal device 2 that is the destination of the shopping memo may be, for example, the user terminal device 2 that is the source of the shopping memo transmission request. Note that the user identifier and the shopping memo transmission request may be received at the same time or at different timings, for example. Even in the latter case, it is preferable to know the correspondence between the two. For example, if a shopping memo transmission request is received while the user is logged in, it can be determined that the user identifier of the logged-in user corresponds to the shopping memo transmission request. In this case, the user identifier received from the user terminal device 2 when the user logs in may be the user identifier corresponding to the shopping memo transmission request. It is assumed that the same applies when the user identifier and other information are received by the receiving unit 12 .

The transmission unit 14 may transmit purchase plan information, which will be described later, to the store terminal device 3 . The store terminal device 3, which is the destination of the purchase plan information about the product posted on a leaflet, is the store terminal device 3 of the store that advertised the leaflet. For example, the storage unit 11 may store a code identifier in association with the address of the shop terminal device 3 of the shop that advertises with a leaflet displaying the code identified by the code identifier. Then, the transmission unit 14 may transmit, for example, purchase plan information regarding a product published in a leaflet to an address corresponding to the code identifier of the code displayed on the leaflet. The purchase plan information may be transmitted, for example, at regular or irregular time intervals, or may be transmitted in response to the receiving unit 12 receiving a transmission request for the purchase plan information transmitted from the store terminal device 3. may be

The transmission unit 14 may also transmit non-purchased product information, which will be described later. The destination of the non-purchased product information may be, for example, the store terminal device 3, the user terminal device 2, or both. The shop terminal device 3 that is the transmission destination of the non-purchased product information may be, for example, the shop terminal device 3 that is the transmission source of the purchased product information. Also, the user terminal device 2 to which the non-purchased product information is transmitted may be, for example, the user terminal device 2 of the user identified by the user identifier included in the purchased product information. In this case, for example, the storage unit 11 may store the user identifier and the address of the user terminal device 2 of the user identified by the user identifier in association with each other. Then, the transmission unit 14 may transmit the non-purchased product information acquired using the purchased product information to the address corresponding to the user identifier included in the purchased product information.

The transmission unit 14 may or may not include a transmission device (eg, modem, network card, etc.) for transmission. Also, the transmission unit 14 may be implemented by hardware, or may be implemented by software such as a driver for driving the transmission device.

The accumulation unit 15 accumulates in the storage unit 11 the code identifier and the reception history related to the product detail information transmission request. The reception history may be information including, for example, the date when the code identifier or the detailed product information transmission request was received, and the received code identifier or the product identifier included in the detailed product information transmission request. If the product detail information transmission request also contains a code identifier, the reception history may also contain the code identifier. In addition, the reception history may include the reception time as well as the date. The accumulation unit 15 may acquire the date and time from, for example, a calendar unit or a clock unit (not shown). The reception history may also include, for example, a code identifier and a user identifier of the user who sent the product detail information transmission request. Also, it is preferable that the reception history is usually such that the corresponding code identifier can be known. In other words, it is preferable to be able to specify the reception history corresponding to a certain handbill.

The analysis unit 16 analyzes the effect of the flyer based on the reception history accumulated in the storage unit 11 by the accumulation unit 15 . The analysis of the effect of leaflets may be, for example, an analysis of the number of views for each leaflet, an analysis of the number of views for each product detail information, or the like. This analysis may be performed, for example, using the number of paper leaflets distributed and the number of times the code identifier of the code displayed on the leaflet was received. Specifically, acquisition of the number of views of the leaflet, identification of products that have received particular attention in the leaflet, and the like may be performed. Normally, it is considered that there is a positive correlation between the number of views of a paper medium leaflet and the number of times the server device 1 receives the code identifier of the code displayed on the leaflet. Therefore, the analysis unit 16 may, for example, predict the number of times a paper leaflet has been viewed using the number of times the code identifier has been received, and divide the number of times the code identifier has been received by the number of paper leaflets distributed. may predict the number of leaflets that have been viewed among the distributed leaflets, and by comparing the value obtained by dividing the number of times the code identifier is received by the number of paper leaflets distributed for each leaflet, Flyers with a high percentage of views may be identified. In addition, for a certain leaflet, by dividing the number of times a request to send product detail information for each product identifier is received by the number of times a code identifier is received, the product detail information of which product is viewed more than other product detail information. It is also possible to identify whether The number of times the code identifier is received, the number of times the detailed product information transmission request is received, and the like can be obtained using the reception history accumulated by the accumulation unit 15 . Also, the number of receptions may be, for example, the total number of receptions or the number of unique receptions. In the latter case, for example, even if the user identifier is included in the reception history and the same user has received the message twice or more, the number of receptions may be obtained by counting it as one time. . Moreover, when the date and time are included in the reception history, the analysis unit 16 may perform analysis using the date and the like. Specifically, the analysis may be performed using only the reception history for the period corresponding to the leaflet, or the analysis may be performed for each predetermined period (for example, every day or every week). The analysis result by the analysis unit 16 may be output by an output unit (not shown). The output may be, for example, display, printing, transmission, or the like.

When the receiving unit 12 receives the user identifier and the product identifier, the creating unit 17 adds the received product identifier to the shopping memo associated with the user identifier in the storage unit 11 . When the quantity is also received together with the product identifier, the creation unit 17 may add the quantity to the shopping memo in association with the product identifier. In this way, the shopping memo is created by the creation unit 17 adding the product identifier to the shopping memo. The product identifier contained in the shopping memo is usually preferably the product name.

The purchase schedule acquisition unit 18 acquires purchase schedule information that associates product identifiers with the number of product identifiers from a plurality of shopping memos. This purchase plan information can also be considered as a result of merging the contents of shopping memos of a plurality of users. For example, the purchase schedule acquisition unit 18 merges a plurality of shopping memos corresponding to a store stored in the storage unit 11, and counts the number of product identifiers included in the information after merging. Purchase plan information that associates product identifiers with the number of product identifiers may be acquired. Note that if the shopping memo includes both the item identifier and the number of items, the purchase schedule acquisition unit 18 counts the number of item identifiers included in the information after merging. may be taken into account and counted. That is, when counting a product identifier, the purchase schedule acquisition unit 18 may add the number corresponding to the product identifier instead of simply adding one. In this way, it is possible to know the total number of items added to the shopping memo for each product. By transmitting this purchase plan information to the store terminal device 3, the store employee can predict how much the product posted on the leaflet will sell. For example, in the purchase plan information, if the number of items corresponding to a product identifier exceeds the number of products identified by the product identifier in stock at the store, the employee of the store will immediately receive the product. By arranging so, it may be possible to avoid the situation where the product is sold out. If shopping memos are stored for each code identifier or each store, the purchase plan acquisition unit 18 may acquire purchase plan information for each code identifier or each store. Then, the purchase plan information may be transmitted to the store corresponding to the code identifier or the shop corresponding to the shopping memo used to obtain the purchase plan information.

Further, the purchase plan information may be obtained using all the shopping memos stored in the storage unit 11, or may be obtained using some of the shopping memos. As described above, since the purchase plan information is used to secure inventory at the store, the shopping memo should not be used to acquire the purchase plan information after the shopping is done according to the shopping memo. is preferred. Therefore, for example, a certain user's shopping memo corresponding to a certain code identifier is used to acquire purchase plan information after purchasing product information about the user is received from the store terminal device 3 of the store corresponding to the code identifier. May not be used. Further, for example, the shopping memo transmitted in response to the reception of the shopping memo transmission request may not be used for acquiring the purchase plan information after the transmission. This is because there is a high possibility that the product will be purchased using the shopping memo after the transmission.

When the receiving unit 12 receives the purchased product information, the unpurchased product acquisition unit 19 includes in the shopping memo associated with the user identifier included in the purchased product information, and is included in the purchased product information. Get unpurchased product information that includes product identifiers that are not included. The product identifiers included in this unpurchased product information are product identifiers that identify products that have not been purchased among the product identifiers added to the shopping memo by the user. Therefore, the product identified by the product identifier included in the unpurchased product information may be the product that the user forgot to buy. By being transmitted to the store terminal device 3 and output by those devices, it is possible to alert the user to forgetting to buy the product. When the unpurchased product information is transmitted to the user terminal device 2, for example, the user terminal device 2 of the user identified by the user identifier included in the purchased product information used to acquire the unpurchased product information may be sent to When the unpurchased product information is transmitted to the store terminal device 3, for example, it may be transmitted together with the user identifier included in the purchased product information used to acquire the unpurchased product information. . This is so that the corresponding relationship between the unpurchased product information and the user can be understood in the store terminal device 3 . If there is no shopping memo corresponding to the user identifier included in the purchased product information, for example, the unpurchased product acquisition unit 19 does not need to acquire the unpurchased product information. As a result, transmission of unpurchased product information may not be performed. Further, when all the product identifiers included in the shopping memo corresponding to the user identifier included in the purchased product information are included in the product identifiers included in the purchased product information, the unpurchased product acquisition unit 19, for example, , null unpurchased product information may be acquired, or no unpurchased product information may be acquired. Also, in the former case, null unpurchased product information may or may not be sent. Also, for example, the shopping memo used to acquire the non-purchased product information may be deleted from the storage unit 11 .

Next, the operation of the server device 1 will be described using the flowcharts of FIGS. 3A and 3B.

(Step S101) The receiving unit 12 determines whether or not a code identifier has been received. If the code identifier has been received, the process proceeds to step S102; otherwise, the process proceeds to step S105.

(Step S109) The creation unit 17 identifies the shopping memo associated with the received user identifier by the user shopping memo information, and adds the received product identifier to the shopping memo. Then, the process returns to step S101.

(Step S110) The receiving unit 12 determines whether or not the user identifier and the shopping memo transmission request have been received. If they have been received, the process proceeds to step S111; otherwise, the process proceeds to step S112.

(Step S<b>111 ) The transmission unit 14 reads the shopping memo associated with the received user identifier by the user shopping memo information from the storage unit 11 and transmits it to the user terminal device 2 . Then, the process returns to step S101.

(Step S112) The purchase plan acquisition unit 18 determines whether or not to acquire purchase plan information. If the purchase plan information is to be acquired, the process proceeds to step S113; otherwise, the process proceeds to step S115. The purchase schedule acquisition unit 18 may determine to acquire the purchase schedule information, for example, when a transmission request for the purchase schedule information is received from the store terminal device 3, or may periodically determine to acquire the purchase schedule. You may

(Step S<b>113 ) The purchase plan acquisition unit 18 acquires purchase plan information using a plurality of shopping memos stored in the storage unit 11 .

(Step S<b>114 ) The transmission unit 14 transmits the acquired purchase plan information to the store terminal device 3 . Then, the process returns to step S101.

(Step S115) The receiving unit 12 determines whether or not purchased product information has been received. Then, when the purchase product information is received, the process proceeds to step S116, otherwise, the process proceeds to step S118.

(Step S116) The unpurchased product acquisition unit 19 acquires unpurchased product information using the received purchased product information and the shopping memo corresponding to the user identifier included in the purchased product information.

(Step S117) The transmission unit 14 transmits the acquired unpurchased product information. Then, the process returns to step S101. For example, if the unpurchased product information is not acquired or null unpurchased product information is acquired, the unpurchased product information need not be transmitted.

(Step S118) The analysis unit 16 determines whether or not to analyze the effect of leaflets. If it is to be analyzed, the process proceeds to step S119; otherwise, the process returns to step S101. Note that the analysis unit 16 may, for example, periodically determine that the analysis should be performed, or may determine that the analysis should be performed when an instruction to perform the analysis is received.

(Step S119) The analysis unit 16 uses the reception history accumulated by the accumulation unit 15 to analyze the effect of the flyer. This analysis result may be accumulated in the storage unit 11, for example, or may be output. Then, the process returns to step S101.

The order of processing in the flowcharts of FIGS. 3A and 3B is an example, and the order of steps may be changed as long as similar results can be obtained. In addition, in the flowcharts of FIGS. 3A and 3B, the processing ends when the power is turned off or when the processing ends.

Next, the operation of the information communication system according to this embodiment will be described using a specific example. In this specific example, the user identified by the user identifier "U001" (hereinafter also referred to as "user U001") uses the code 5a displayed on the leaflet 5 shown in FIG. It is assumed that the URL corresponding to the code 5a is obtained by photographing with the user terminal device 2, and the code identifier "C001" of the code 5a is transmitted to the server device 1 by accessing the URL. The code identifier transmitted in this manner is received by the receiving unit 12 and passed to the identifying unit 13, the transmitting unit 14, and the storing unit 15 (step S101).

In this specific example, it is assumed that the storage unit 11 stores product correspondence information shown in FIG. The product correspondence information in FIG. 5 includes code identifiers and product information corresponding to the code identifiers. The product information includes a product identifier, a product image that is image data of the product identified by the product identifier, and detailed product information that is detailed information on the product identified by the product identifier. The product identifier is the name of the product, and the detailed product information includes the product price, calorific value, and allergen. The allergen is information indicating which of the seven specific raw materials are included in the product. For example, the code identifier "C001" is associated with product information such as the product identifiers "ABC banana" and "BBB corn" of the product posted on the leaflet 5 displaying the code 5a identified by the code identifier. It is In addition, the product image may be included in the detailed product information.

Upon receiving the received code identifier "C001", the specifying unit 13 searches the product correspondence information using the code identifier as a search key, specifies and transmits all product identifiers associated with the hit code identifier. It is passed to the unit 14 (step S102). Further, upon receiving the received code identifier, the transmission unit 14 acquires browsing information indicating that the leaflet 5 displaying the code 5a identified by the code identifier "C001" has been browsed. It is assumed that the browsing information includes the code identifier "C001" and the code image data obtained by converting the code identifier into a two-dimensional code. Further, when receiving a plurality of product identifiers from the identification unit 13, the transmission unit 14 uses the address of the source of the code identifier as a transmission destination, and corresponds to the product list including the received multiple product identifiers and the code identifier "C001". The viewing information to be viewed is transmitted (step S103). The transmitted product list and browsing information are received by the user terminal device 2 of the user U001, and each product identifier included in the product list is displayed as shown in FIG. 2 is stored. In FIG. 6A, a "details" button for requesting transmission of detailed product information and a "register" button for registering the product in the shopping cart are displayed in association with each product identifier.

Further, upon receiving the received code identifier "C001", the storage unit 15 acquires the date and time at that time, and stores the reception history including the date and time and the code identifier in the storage unit 11. (step S104).

Next, when the user U001 taps the "details" button corresponding to the product identifier "ABC banana" on the display of the user terminal device 2 shown in FIG. 6A, the product identifier "ABC banana" and the code identifier of code 5a are displayed. A product detailed information transmission request including “C001” is transmitted to the server device 1 . The detailed product information transmission request is received by the receiving unit 12, and the code identifier and product identifier included in the detailed product information are passed to the transmitting unit 14 and the storage unit 15 (step S105).

Upon receiving the code identifier and the product identifier, the transmission unit 14 searches the product correspondence information using the received code identifier as a search key, and searches the product information corresponding to the hit code identifier using the received product identifier as the search key. Then, the product image and detailed product information associated with the hit product identifier are acquired and transmitted to the user terminal device 2 that is the source of the detailed product information transmission request (step S106). The transmitted product image and detailed product information are received by the user terminal device 2 and displayed as shown in FIG. 6B. This display allows the user U001 to know detailed information about the product.

Further, when receiving the received code identifier and product identifier, the storage unit 15 acquires the date and time at that time, and stores the reception history including the date and time, the code identifier and the product identifier. It is stored in the storage unit 11 (step S107). As a result, the reception history shown in FIG. 7 is stored in the storage unit 11 . In FIG. 7, the reception history includes the date, etc., when the code identifier, etc., was received, and information included in the received code identifier, and the product detail information transmission request.

After that, when the user U001 taps the "shopping memo registration" button on the display shown in FIG. It is transmitted to the server device 1 . The product identifier and the like are received by the receiving unit 12 and transferred to the creating unit 17 (step S108). Then, the creation unit 17 searches the user shopping memo information stored in the storage unit 11 using the received user identifier “U001” as a search key, and stores the received product identifier in the shopping memo corresponding to the hit user identifier. "ABC Banana" is added (step S109). It is assumed that the user U001 similarly registers product identifiers such as "BCD bread" and "CCC milk" in the shopping memo. Then, the user shopping memo information stored in the storage unit 11 becomes as shown in FIG. In FIG. 8, the user shopping memo information includes a user identifier and the shopping memo of the user identified by the user identifier. In addition, the shopping memo contains product identifiers registered by the user. In FIG. 8, the shopping memo includes only product identifiers, but in the shopping memo, the product identifiers may be associated with code identifiers. By doing so, shopping memos can be managed for each leaflet.

Next, when it is determined that it is time to acquire the purchase plan information, the purchase plan acquisition unit 18 acquires the purchase plan information and passes it to the transmission unit 14 (steps S112 and S113). The purchase plan acquisition unit 18 may determine to acquire the purchase plan information periodically, such as every hour. Further, the purchase plan acquisition unit 18 may acquire product identifiers included in all shopping memos stored in the storage unit 11 and count the number of product identifiers to acquire purchase plan information. . It is assumed that the purchase plan information acquired in this manner is as shown in FIG. The purchase plan information in FIG. 9 includes product identifiers and the number of products whose product identifiers are included in the shopping memo. For example, the product identifier "ABC Banana" was registered in shopping memos by 72 users. Upon receiving the purchase plan information, the transmitting unit 14 transmits the received purchase plan information to the address of the store terminal device 3 set in advance (step S114). The transmitted purchase plan information is received by the store terminal device 3 and output. Then, according to the output purchase schedule information, the store employee can predict the sales of the product. By arranging, it is possible to prevent stockout from occurring.

Next, it is assumed that the user U001 goes to a store selling the product on the leaflet 5 and performs an operation to display browsed information on the user terminal device 2 . Then, as shown in FIG. 6C, the browsing information stored in advance is displayed. The user U001 browses the leaflet 5 on which the code identified by the code identifier "C001" is displayed by viewing this display or by reading the displayed two-dimensional code. As a result, the user U001 will be able to receive services and the like accordingly.

Assume that the user U001 performs an operation to transmit a shopping memo transmission request to the server device 1 at the store. Then, the user terminal device 2 transmits the user identifier and the shopping memo transmission request to the server device 1 . Those pieces of information are received by the receiving unit 12 and transferred to the transmitting unit 14 (step S110). Upon receiving the user identifier and the shopping memo transmission request, the transmission unit 14 searches the user shopping memo information using the user identifier as a search key, and searches for the shopping memo corresponding to the hit user identifier, i. is read out and transmitted to the user terminal device 2 that is the source of the shopping memo transmission request (step S111). The transmitted shopping memo is received by the user terminal device 2 and displayed as shown in FIG. 6D. This display reminds the user of the product to be purchased and prevents the user from forgetting to purchase the product.

After that, assume that the user U001 purchases an item at the cash register by presenting the membership card at the store. The store terminal device 3 can acquire the user identifier “U001” of the user by presenting the membership card, and can acquire the product identifier of each product to be purchased by purchasing the product at the cash register. In this way, the shop terminal device 3 can acquire purchased product information including the user identifier and the product identifier of the product purchased by the user identified by the user identifier. 1. The transmitted purchased product information is received by the receiving unit 12 and passed to the unpurchased product acquisition unit 19 (step S115). Upon receiving the purchased product information, the unpurchased product acquisition unit 19 searches the user shopping memo information using the user identifier included in the purchased product information as a search key, and retrieves each product included in the shopping memo corresponding to the hit user identifier. Get an identifier. Among the product identifiers acquired from the shopping memo, product identifiers not included in the purchased product information are identified, and the unpurchased product information including the identified product identifiers and the user identifiers included in the purchased product information are identified. is passed to the transmission unit 14 (step S116). In this specific example, it is assumed that the product identifier "BCD bread" is included in the unpurchased product information. The transmitting unit 14 transmits the received unpurchased product information to the user terminal device 2 corresponding to the user identifier "U001" (step S117). The transmitted unpurchased product information is received by the user terminal device 2 of the user U001. Then, on the user terminal device 2, as shown in FIG. 6E, an alert for forgetting to buy is displayed. With this display, the user U001 can be alerted to forgetting to buy BCD bread, and can prevent forgetting to buy.

Also, when it comes time to analyze the effect of the flyer 5, the analysis unit 16 performs the analysis (steps S118 and S119). Specifically, the analysis unit 16 may refer to the code identifier and the reception history of the detailed product information transmission request, and may identify the degree of viewing of the leaflet 5 and the frequently accessed product. Then, the analysis result may be output to the administrator of the server device 1, an analyst who analyzes the effect of the leaflet, or the like.

As described above, according to the server device 1 according to the present embodiment, the product identifier and the detailed product information of the product posted on the leaflet are associated with the code identifier for identifying the code displayed on the leaflet. By being managed, it is possible to transmit to the user terminal device 2 the product identifier of the product posted on the leaflet and the detailed product information. Therefore, the user can easily acquire detailed information about the products listed on the leaflet by operating the user terminal device 2 and photographing the code displayed on the leaflet, for example. . In addition, by accumulating the history of access from the user terminal device 2, it becomes possible to analyze the effect of paper leaflets, which has been difficult in the past. Conventionally, in order to prove that you have seen the leaflet, it was necessary to bring the leaflet itself or a cut coupon displayed on the leaflet to the store. By outputting the information on the user terminal device 2, it is possible to prove that the leaflet has been seen, and it is possible to receive a corresponding service or discount.

In addition, the user can add the product identifier of the product posted on the leaflet to the shopping memo, and view the shopping memo on the user terminal device 2, thereby preventing forgetting to buy. In addition, since the shopping memo is managed by the server device 1 rather than by each terminal, for example, the product identifier is registered in the shopping memo using a tablet terminal at home, and the shopping memo is registered using a smartphone at the store. can also be confirmed, and the user's convenience is improved. In addition, since the store can receive the purchase plan information acquired using the shopping memo, it is possible to predict the sales of the products posted on the flyer, and to respond in advance according to the prediction. be able to do it. Further, by transmitting purchased product information from the shop terminal device 3 to the server device 1 and acquiring and transmitting unpurchased product information using the purchased product information and the shopping memo, the user's forgetting to purchase can be more reliably prevented. can be prevented.

Next, a modification of the server device 1 according to this embodiment will be described.
[Acquisition of purchase plan information according to the result of comparison between purchase product information and shopping memo]
As described above, the store can use the purchase plan information transmitted from the server device 1 to secure the inventory of the product. On the other hand, not all product identifiers registered in the shopping memo by the user are purchased. For example, it is conceivable that a user who has registered a product identifier in a shopping memo may not go to the store. Also, it is conceivable that the product with the product identifier registered in the shopping memo will not be purchased. Therefore, purchase plan information may be acquired in consideration of such matters. Therefore, the server device 1 may further include a comparison unit 21 as shown in FIG. 2B. When the purchased product information is received by the receiving unit 12, the comparing unit 21 compares the purchased product information with the shopping memo corresponding to the user identifier included in the purchased product information, and outputs the comparison result to the It may be stored in the storage unit 11 in association with the user identifier. The comparison may be a comparison between the product identifier included in the purchased product information and the product identifier included in the shopping memo. The comparison result may be, for example, information indicating the ratio of products whose purchase is indicated by the purchased product information among the product identifiers included in the shopping memo. That is, the comparison result is, for example, a value obtained by dividing the number of product identifiers included in the shopping memo and also included in the purchased product information by the total number of product identifiers included in the shopping memo (this value is hereinafter referred to as may also be called a “purchase ratio”). If the number of items is included in the shopping memo or purchased item information in association with the item identifier, the comparison result may be acquired in consideration of the number of items. A comparison result may be obtained using all shopping memos stored in the storage unit 11 for a certain user. If all product identifiers included in the shopping memo have been purchased, the purchase ratio, which is the comparison result, is "1". On the other hand, if only half of the items have been purchased, the purchase ratio is "0.5".

Further, the purchase plan acquisition unit 18 may correct the number of product identifiers using the comparison result of the comparison unit 21 when acquiring the purchase plan information. For example, when counting the number of product identifiers included in a user's shopping memo, a value obtained by multiplying the purchase ratio, which is the comparison result associated with the user identifier of the user, may be counted. For example, if a certain user's purchase ratio is "0.5" and the user's shopping memo contains only product identifiers, "0.5 ' may be added to the total count, and if the user's shopping memo contains a product identifier and a quantity, then '0.5 ' may be added to the total number of counts. That is, when adding the number of product identifiers included in the shopping memo for each user, the purchase schedule acquisition unit 18 performs weighted addition using the purchase ratio of each user as a weight, thereby obtaining the number corresponding to the product identifier. may be obtained.

Since purchased product information is not transmitted unless the product is purchased at the store, even if the user registers the product identifier in the shopping memo, if the user does not go to the store, the purchased product information does not exist. . In this case, the comparison unit 21 may compare the purchased product information, which is null, with the shopping memo.

By acquiring the purchase plan information using the comparison result in this way, it is possible to improve the accuracy of the purchase plan information. can be avoided.

[Identification of Product Identifier According to User Attribute Information]
The identifying unit 13 may identify the product identifier associated with the code identifier according to attribute information indicating user attributes. In this case, the storage unit 11 may store a plurality of pieces of user attribute information that associate a user identifier with attribute information indicating attributes of a user identified by the user identifier. The attribute information may be, for example, information indicating the user's preferences, information indicating the user's intake restrictions, demographic attributes such as the user's age and gender, and other information about the user. may be information indicating the attributes of

The information indicating the user's preference may be information indicating the type of product that the user likes (for example, "confectionery", "fruit", etc.). Also, the information indicating the user's intake restriction may be information indicating an allergen such as "soba" or "shrimp". Also, demographic attributes may be, for example, "male", "female", "minor", "adult", and the like.

In this case, it is preferable that the receiving unit 12 receives the user identifier and the code identifier. As described above, both may be received together, or may be received separately if the correspondence is known. Then, when the receiving unit 12 receives the user identifier and the code identifier, the specifying unit 13 selects the product associated with the code identifier according to the attribute information associated with the user identifier. An identifier may be specified. More specifically, the identifying unit 13 first tentatively identifies the product identifier associated with the received code identifier, and then identifies the attribute information associated with the received user identifier. Accordingly, a final product identifier may be specified from the provisionally specified product identifier. Specifying the product identifier according to the attribute information may be, for example, specifying only a part of product identifiers among the product identifiers associated with the code identifiers according to the attribute information. The order of product identifiers in the product list may be determined according to the information. In the latter case, it is preferable that the product list is displayed on the user terminal device 2 in the order of the product identifiers determined by the identifying unit 13 . In specifying the product identifier according to the attribute information, product detailed information associated with the product identifier or other information may be used in the product information. In this case, the product information may include information used to specify the product identifier corresponding to the attribute information (for example, information indicating product type, allergen information, etc.).

Specifically, when the attribute information is information indicating the user's preference, the product identifier may be specified such that the product identifier of the user's favorite product is displayed at the top of the product list. In this case, specifying product identifiers according to attribute information may be considered as specifying product identifiers in the order according to attribute information. In this case, the product information may include information indicating the type of product identified by the product identifier. For example, product information including a product identifier “ABC banana” may include information indicating product types such as “banana” and “fruit”. Then, when the attribute information indicating the user's preference includes "banana" or "fruit", the specifying unit 13 uses the product correspondence information to specify the product identifier corresponding to the code identifier "C001". When doing so, the product identifier "ABC banana" included in the product information including "banana" and "fruit" may be specified so as to be ranked higher.

Further, when the attribute information is information indicating intake restriction, the specifying unit 13 does not have to specify the product identifier of the product subject to the intake restriction. For example, when the attribute information indicating the user's intake restriction includes the allergen "shrimp", the identification unit 13 uses the product correspondence information shown in FIG. When specifying , it is not necessary to specify the product identifier "DDD shrimp" whose detailed product information includes "allergen: shrimp".

Further, when the attribute information is a demographic attribute, the specifying unit 13 may specify only the product identifier of the product that matches the demographic attribute, so that the product that matches the demographic attribute is ranked higher. may specify the product identifier. In this case, the product information may include demographic attributes of the users to whom the product is sold. For example, product information for cosmetics and perfumes may include the demographic attribute "female". Then, when the attribute information of the user includes "female", the specifying unit 13 may specify only the product identifier included in the product information including "female". Product identifiers may be specified so as to be higher.

Also, if the product is a home appliance, the attribute information may be, for example, the manufacturer name of the product purchased by the user in the past, the price of the product, the color of the product, the time of purchase of the product, and the like. Such information may be associated with information indicating the type of home appliance (for example, refrigerator, washing machine, air conditioner, etc.). In this case, it is preferable that the product information also includes information indicating the type of home electric appliance. Then, the specifying unit 13 may specify the product identifier so that the product of the manufacturer included in the attribute information is displayed at the top, and the product whose price is close to the price included in the attribute information is displayed at the top. Alternatively, the product identifier may be specified so that the product with the color included in the attribute information is displayed at the top. Products that have been purchased by the user in the past are considered to be products that the user likes. By specifying product identifiers in this way, products that match the user's preferences are displayed at the top. A product identifier can be specified. Identification of such product identifiers may be performed, for example, for each type of home appliance. In addition, if the period from the latest purchase included in the attribute information for a certain type of home appliance exceeds the average number of years of use for that type of home appliance, the product of that home appliance type is You may specify a product identifier so that it may be displayed on a higher rank. By performing such identification, the product identifier of the home appliance at the time of replacement is displayed at a higher rank in the product list.

When product identifiers are specified according to attribute information, the number of product identifiers to be specified may be less than in other cases, but the order of product identifiers is changed using attribute information. In this case, the same number of product identifiers as when attribute information is not used are specified.

In addition, when a shopping memo is created in the server device 1, the user's preferences can be acquired using the shopping memo. Then, the user's preference may be registered in the user's attribute information. Therefore, the server device 1 may further include an updating unit 22 as shown in FIG. 2C. The updating unit 22 may update the attribute information corresponding to the user identifier associated with the shopping memo stored in the storage unit 11 according to the product identifier included in the shopping memo. For example, if past shopping memos are also stored in the server device 1, it is possible to identify product identifiers and product types that are frequently included in shopping memos. A product identifier with a high percentage of inclusion in shopping memos may be, for example, a product identifier whose percentage of inclusion in shopping memos exceeds a predetermined threshold (for example, 80%), and the percentage of inclusion in shopping memos is high. It may be a product identifier that is within a predetermined number from the first (for example, a product identifier that is included in the shopping memo in the top three or the top five). The same applies to product types.
