Commodity sales support system

Abstract

[Problem] To provide a commodity sales support system that can be operated and utilized while allowing an advertising agency of commodities, a seller, and an introducer of chained customers to establish a rational relationship. [Solution] The present invention constructs a system capable of changing an attribute part of an introducer ID for each introducer ID registration of a specific commodity, uploading commodity demonstration sales information on an online shop of the incorporated commodity to the Internet communication network from the server device of a "seller" or an "advertising agency", generating a two-dimensional code including information on a link to the demonstration sales information of the commodity, reading the two-dimensional code into a subsequent introducer terminal device, repeating subsequent introducer ID registration, and growing the number of introducers of the specific commodity by successively chaining the terminal devices of the introducers of the commodity.

Description

Product sales support system

[0001] The present invention relates to a product introduction and sales method that reads a two-dimensional code attached to a product or placed near an image that specifically represents the product, and recommends, mediates, arranges, or introduces the product to support sales, and relates to a product sales support system that can multiply introducers linked to the product in a chain, and when a user from an introducer at the end of the chain purchases the product, can pay an introduction fee in installments to all introducers in the chain.

[0002] A known product sales method involves using a two-dimensional code (such as a barcode or QR code (trademark)) printed on a card or pamphlet introducing a product to direct users to an online shop (e-commerce site) for the product, supporting the sale of the product printed on the card or pamphlet, and receiving a referral fee. (See, for example, Prior Art Document 1, JP 2006-126948.) Another example of prior art, for example, Prior Art Document 2 (see, JP 2023-119732), describes a product sales method in which a two-dimensional code identifying the product and an introducer code are separately written, and information about the product and the introducer is detected and transmitted by a terminal device of a user who purchases the product. A server device provided for operating this system receives the information, and the introducer of the product receives a referral fee.

[0003] In the product sales method / system described in Prior Art Document 1, a "seller" who manages an online shop and sells the product collaborates with physical stores such as restaurants and EC site shops that sell other types of products, and sets these stores as introducers of the product. The store distributes pamphlets containing a two-dimensional code that combines the identification of the introduced product and introducer ID information to customers, or has the pamphlet included in deliveries of products sold on the EC site, thereby obtaining sales support. The method / system then pays an introduction fee to the restaurant or EC site using information from a server device that records the success history of the sales.

[0004] The product sales method / system described in Prior Art Document 2 is an improvement over Prior Art Document 1 in that, rather than combining the identification of the introduced product with introducer ID information in a two-dimensional code, these are set as separate two-dimensional codes to obtain performance-based reward payment data for the introducer. According to this, a new two-dimensional code is prepared that incorporates the two-dimensional code of the introducer ID and the URL information for the online shop content of the product in question, in order to obtain the introducer ID information for each product required by the system, and the introducer is a single entity, not a mechanism that allows for chains or proliferation.

[0005] JP 2006-126948 A JP 2023-119732 A

[0006] The invention in Prior Art Document 1 does not explicitly state how many customers each restaurant or e-commerce site that distributed the card or pamphlet referred, whether those customers then referred customers to subsequent customers, or whether there was a chain of referrals to subsequent introducers, or how the chain of referrals was expanded. It also fails to state how the method / system of the invention would determine which introducer in the chain of referrals was responsible for the referrals and product sales via those introducers. Naturally, it also fails to state how the referral fees would be distributed to introducers in the case of a chain of referrals. Furthermore, like Prior Art Document 1, the invention in Prior Art Document 2 also fails to discuss the content or effects of the above points.

[0007] According to one embodiment of the present invention, a terminal device such as a mobile phone (smartphone) or a personal computer that reads a two-dimensional code (representing a barcode or QR code (trademark), hereinafter referred to as a two-dimensional code) that incorporates information identifying the product (product ID), explanatory sales information for the product, and URL transfer link information linking to an online shop that contains information that allows the user to select whether to "purchase" or "introduce" the product to others, attached to the product or displayed near an image representing the product in a browser on an Internet communication network, or that reads an image or text data that incorporates the URL transfer link information and is displayed on the browser, can view the online shop content for the product managed and operated by the "seller (advertiser)" of the product via the Internet communication network, and can select whether to "purchase" the product or "introduce" the product to others, etc., and transmits that information over the Internet communication network so that it can be received by the server devices of the "seller" and "advertising agency." If the terminal device decides to "purchase the product," the "seller (advertiser)" will proceed to billing for the product purchase price, settlement, and shipping procedures, as per the usual routine of an online shop.

[0008] However, in the present invention, when the terminal device decides to "introduce" the product to another person, the server device of the "seller" publishing the online shop content requests the terminal device to confirm the setting of product ID information identifying the product, such as the product number, and introducer ID information identifying the introducer, and transmits this information to a server device of, for example, an "advertising agency" that undertakes advertising the product. Here, if the number of types and product numbers of the product, i.e., the number of product IDs identifying the product, is small, the present invention can be realized by integrating the functions of the "advertising agency" server device into the "seller" server device, and calling it the "seller's" server device. In fact, up to Figures 1 and 2 in the description of the "Embodiment for the Present Invention," the server device is described as a single entity. From there, the "seller" is described as server device A, and the "advertising agency" is described as server device B.

[0009] In this explanation, the server devices of the "seller" and the "advertising agency" will be described separately so that the present invention can be applied even when the type and number of product numbers of the relevant product are diverse and numerous and there are multiple "sellers." The server device of the "advertising agency" records and accumulates the introducer ID as the introducer of the relevant product linked to the relevant product ID, repeatedly every time a new introducer is generated. However, the server device records and accumulates the introducer IDs registered chronologically for each relevant product ID, by chain order and by chain order number within that chain order, and is configured to sequentially record, accumulate, and store the chain trajectory of the introducer's chain order and chain order number, and whether the next user introduced to the relevant product by that introducer chose to "purchase" the product, "introduce" it to another person, or both. Here, in the explanation of this product sales support system (hereinafter, this product sales support system may be referred to as the system of the present invention), "purchase" may also be referred to as "order" or "placement order" in some cases, but in the explanation of the system of the present invention below, it will always be referred to as "purchase." Similarly, "introduction" may also be referred to as "recommendation," "mediation," "intermediation," or "recommendation" in some cases, but in the explanation of the system of the present invention below, it will always be referred to as "introduction."

[0010] Furthermore, as shown in FIG. 1 , the present invention can also be configured as follows: The server device of the "seller" or "advertising agency" associates the terminal device that has registered an introducer ID associated with the product ID as the first in the chain order of the introducer ID. A new two-dimensional code incorporating the introducer ID containing the chain order information and link URL transfer information to the online shop content of the product is generated and transmitted to the terminal device. This newly generated two-dimensional code is displayed on terminal device 1 (1 of 1) that is ranked first in the chain order and has the introducer ID registered. Terminal device 2 (2 of 1) of the next user then displays and views the online shop content containing the attributes of terminal device 1 (1 of 1) via a link transfer based on the information in the two-dimensional code. The terminal device of the user who registered the introducer ID to "introduce" the product to another person is recognized by the server device of the "seller" or "advertising agency" as ranked second in the chain order. This process is repeated for new users, and the chain order of the registered introducer ID is set and recognized as 3rd, 4th, Nth, etc. Also, for example, if a user has the same chain order of 2nd but is the second person to register as an introducer for the product in chronological order, that introducer ID will be recorded in the server device of the "seller" or "advertising agency" as 2-2, which is positioned as the chain order number 2 for the chain order of 2nd.

[0011] In this way, the server device of the "seller" or "advertising agency" generates a unique two-dimensional code for each introducer ID, incorporating information on the chain order and chain sequence number linked to the product ID, and distributes and transmits the code via Internet communications to the terminal device that registered the introducer ID. The registrant of the introducer ID displays the unique two-dimensional code for each introducer ID on their terminal device and has it scanned by the terminal device of the next user they want to link, or displays the code on an SNS or other communication content service on their own Internet communication network, or displays it on printed materials and distributes it, thereby dramatically increasing the number of introducers for the product. Furthermore, a considerable number of these introducers will decide to "purchase" the product, which can greatly support sales of the product. In this case, the unique two-dimensional code generated for each introducer ID can also be linked from text characters or graphics such as a banner displayed on the terminal device, leading to the display of content on an online shop managed and operated by the "seller" that describes and sells the product in question, which can also be realized in the same way as the present invention.

[0012] According to the method / system of the present invention, the structure of the online shop content for an introducer of a product of any chain order or chain sequence number to obtain the next introducer can be configured by changing only a few areas, as described below, while the product description and sales price display for the product remain the same for most areas. The display area for selecting "purchase" or "introduce" the product to others displays online shop content for each introducer ID that guides the user to view the content. This introducer ID attribute information is configured using a transmission function such as CGI so that it can be recognized by the server device of the "seller" or "advertising agency." The server device of the "seller" or "advertising agency" then uploads the online shop content for each introducer ID to the Internet, making it available for the purchaser of the product and the next chain introducer from anywhere on the network. Because the content is configured as described above, even if online shop content is created for multiple introducer IDs, most of the content is identical, resulting in a system that does not require much effort to create.

[0013] So far, as an example of one aspect of the present invention, a method has been described in which the terminal device ranked first in the chain reads a two-dimensional code attached to a product that includes information identifying the product (product ID), explanatory sales information for the product, and URL transfer link information that links to online shop content that allows users to select "purchase" or "introduce" the product, thereby creating the referral chain. In this case, it is necessary to separately generate a new two-dimensional code that combines the product ID information and the URL transfer link information for each product number, and have the terminal device ranked first in the chain read and detect the code, which is time-consuming.

[0014] In contrast, as another example of the present invention, the terminal device ranked first in the chain, which serves as the starting point of the referral chain in the product sales support system of the present invention, declares or registers in advance as an introducer in the product sales support system of the present invention, and is configured to install a product sales support system app that can identify products that are eligible for the system of the present invention and that have been uploaded to the Internet in advance (determine whether the products can participate in the system of the present invention and be involved in the referral chain).As a result, the app is launched first, and the terminal device reads a two-dimensional code, such as a JAN code or EAN code, that identifies products that are commonly sold as accessories to general products for electronic cash register settlement in ordinary stores, and identifies the product.Whether the product is a product that the seller has previously agreed to participate in the product sales support system of the present invention can be confirmed by exchanging information and data between the terminal device that read the two-dimensional code and the seller's server device or the advertising agency's server device, thereby enabling the referral chain that is a feature of the system of the present invention to be carried out. This makes it possible to obtain an efficient product sales system that can continue the chain of product introductions while eliminating the need to attach a two-dimensional code to the target product to identify it in addition to the JAN code in order to allow the product to participate in the system of the present invention.

[0015] Next, a solution to the problem of payment of the product introduction fee for this product will be explained. For example, when a customer (user) selects and decides to "purchase" the product from the content of an online shop directed from a two-dimensional code issued and transmitted to the terminal device of the introducer ID with the first chain ranking, which is linked to the product ID, and the payment for the product is made, the information is received by the server device of the "advertising agency," and a payment notice of 100% of the introduction fee is sent to the "seller" of the product and to the registrant of the introducer ID with the first chain ranking, and the "seller" or the "advertising agency" that has been contracted by the "seller" to perform the work may pay the introduction fee. Furthermore, for example, if a customer appears on the content guided by a two-dimensional code issued and transmitted to an introducer ID with a chain order of second place linked to the product ID, a chain number of, for example, 3 (even if the chain order is the same for 4 or 5), and selects and decides to "purchase" the product in question, the referral fee is divided by the number of steps in the chain order and paid in installments to the higher chain order. If this is established as a rule, the "seller" or "advertising agency" server device will calculate, record, and store the information, and send notifications to each introducer terminal device, so that the introducers with chain order 1 and 2 will each receive half of the total referral fee.

[0016] As described above, if the chain order becomes multi-tiered, for example, the referral fee for an introducer's purchase of a product from the content of an online shop owned by an introducer ID registrant ranked Nth will be shared among the introducers ranked 1 to Nth in the chain order, with each referral fee being 1 / Nth of the total. As the introduction of the product spreads and the chain order expands to multiple tiers, the referral fee per introducer per product may become small. In such cases, the referral fee may be awarded in the form of points, which can be used only at specific companies or stores and are treated like currency. Furthermore, if an introducer ID registrant ranked low in the chain order, for example, ranked 4th or 5th, purchases the product, the server devices of the "seller" and "advertising agency" can detect this and establish appropriate operational rules, such as gradually raising the introducer ID or elevating it to 1st in the chain order. This can be used to increase the introducer's motivation to participate in the method / system of the present invention and produce beneficial results.

[0017] Furthermore, at this time, if the terminal device on which an introducer ID is about to be registered displays in advance what chain ranking linked to the product ID will be if the registration is performed now, and if the user is dissatisfied with this, the user can first "purchase" the product and then register the introducer ID based on the rules, thereby making it possible to register the chain ranking, for example, to first or significantly higher, which will similarly lead to sales support and sales expansion for the product. Also, it is possible to upload content displaying a group of multiple products participating in the system of the present invention from the server device of an "advertising agency" to the Internet communication network, and a person who wishes to register an introducer ID who views this can select multiple products they want to introduce from there, allowing the introducer to easily create an online shop where they can solicit the next introducer or a purchaser of the product.

[0018] Furthermore, the "advertising agency's" server device may be connected to a distributed memory ledger (blockchain) cloud database to record and store the total referral fee for each product sales support referral, the chain ranking, the number of chained people below the introducer ID, and the introducer's own referral fee, etc., according to the present invention, and to communicate and store the stored data for each introducer ID, or to allow the chained introducer to view it himself, thereby creating a system that enhances the integrity and fairness of the stored data.This allows the introducer to know the spread of the referral for each product and to learn in detail about the popularity of the product, which is expected to have the effect of motivating the introducer to chain the introducer to the next introducer.

[0019] The present invention described above has the following significant advantages: (1) For a specific product, the number of users introducing that product can be increased in a chain, like parent, child, and grandchild, and the chain order and sequence can be set and recorded for each introducer ID. This allows the seller, advertising agency, and the registrant of each introducer ID to know the spread of the product introduction chain, leading to effective advertising and sales expansion. (2) Furthermore, when using a terminal device with an application that reads the JAN code attached to the product to identify the product and registers the introducer ID linked to the specific product, the two-dimensional code attached to the product for the system of the present invention can be the JAN code (JIS standard) or EAN code, which are commonly used in the market, which has the effect of building a very easy-to-operate and efficient product sales support system. (3) The server device keeps track of the chain ranking of the registered introducer ID, and when a product purchaser appears at the end of the chain, it can process and notify all introducers in the chain who are higher in the chain so that they can distribute the referral reward divided by the number of levels in the introducer chain. This is expected to have the effect of increasing the introducer's motivation to make introductions and support sales in the referral chain. (4) If the introducer ID is registered with a low chain ranking (4th, 5th, etc.), if the introducer becomes a purchaser and then requests registration of the introducer ID, the chain ranking can be significantly raised or even raised to 1st, which can lead to fostering the introducer's motivation to participate in the system of the present invention. (5) A user's terminal device can easily select products from a group of products participating in the system of the present invention uploaded by the "advertising agency's" server device, and an online shop can be easily built where multiple new products can be introduced for sale to the user, thereby greatly increasing the number of introducer users.(6) The records of the chain spread of introducer IDs by chain rank linked to each product, the accumulated data of the referral reward fee, and the accumulated data of changes in the chain rank of introducer IDs can be stored in a cloud database of a distributed memory ledger (blockchain), which can improve the integrity and fairness of the accumulated data.

[0021] Below, we will explain an embodiment of the system of the present invention. However, because product introducer ID registration is performed in a chained manner, similarly named components of the system of the present invention are described, which can lead to confusion. To avoid this, for ease of understanding, we will clearly state that the following components, even when expressed differently, are the same elements. The first terminal device is the same as terminal device 1, the second terminal device is the same as terminal device 2, and the third terminal device is the same as terminal device 3. The first introducer ID is the same as introducer ID 1-1, which is ranked first in the chain; the second introducer ID is the same as introducer ID 2-1, which is ranked second in the chain; and the third introducer ID is the same as introducer ID 3-1, which is ranked third in the chain. The first two-dimensional code is the same as two-dimensional code 1-1, the second two-dimensional code is the same as two-dimensional code 2-1, and the third two-dimensional code is the same as two-dimensional code 3-1. It should be noted here that the first online shop is identical to online shop 1C1 or 2C1, the second online shop is identical to online shop 1C2 or 2C2, and the third online shop is identical to online shop 1C3.

[0022] Hereinafter, a first embodiment of the product sales support system 1S of the present invention will be described. FIG. 1 is a system configuration diagram showing an overview of the product sales support system 1S of the present invention. A server device 1B of a "seller" who wishes to sell, for example, a product 1A, connected to an Internet communication network 1N uploads online shop content 1C to the Internet communication network 1N, displaying the content so that customers can indicate their intention by pressing a "Purchase" button 1Ca or an "Introduce" button 1Cb for the product. Meanwhile, a two-dimensional code (QR Code (trademark)) 1Q is displayed on paper tags attached to the product 1A in general storefronts or already in the hands of consumers, or on pamphlets promoting the product.

[0023] This two-dimensional code 1Q may be displayed on another content for advertising the product on the Internet communication network 1N, or may be displayed as an image or text character with embedded information linking to a URL on the Internet to which the QR code 1Q transfers the link. The two-dimensional code 1Q incorporates a product ID that identifies the product 1A and URL information for linking to and viewing the online shop content 1C.

[0024] Next, when a user holding, for example, a mobile terminal device (e.g., a smartphone or mobile tablet) 1-1 reads the QR code 1Q, links from the information data to view the online shop content 1C, and selects the "Refer" button 1Cb, the server device 1B generates a new QR code 1-1 for each corresponding product ID, for example, with the chain ranking set to 1st and the chain sequence set to 1st, that includes the introducer information data 1D1 of the introducer ID 1-1 that has been recorded, and also includes the attribute data of the introducer ID 1-1, and that includes the link URL information for the online shop content 1C1 where new "Purchase" and "Refer" options can be selected, and sends this to the terminal device 1-1. Meanwhile, at the same time, the server device 1B generates new online shop content 1C1 in the online shop content 1C in synchronization with the generated data of the QR code 1-1, with the same product description content but with the "Purchase" button 1Ca and the "Referral" button 1Cb modified to incorporate attribute information of the introducer ID 1-1, uploads this content, and is configured to provide feedback to the server device 1B when a new user (customer) presses the "Purchase" button or the "Referral" button in this content, and then uploads this new online shop content 1C1 onto the Internet 1N.

[0025] Next, terminal device 2-1 of user (customer) 2, who has received an introduction and recommendation of product 1A from user 1 of terminal device 1, reads two-dimensional code 1-1 displayed on the screen of terminal device 1-1 and uses the link information from there to view the online shop content 1C1 described above. Here, as before, when the "Introduce" button is pressed on content 1C1, server device 1B stores this introducer's introducer ID as 2-1, with a chain order of 2 and a chain sequence of 1, as introducer information data 1D2 in the introducer information database ID, generates two-dimensional code 2-1 with the same functions as above, sends it to terminal device 2-1, and simultaneously uploads new online shop content 1C2 as before. This process is repeated, and then a newly generated two-dimensional code 3-1 is sent to terminal device 3-1, and similarly, the new online shop content 1C3 is uploaded, and the registration of introducer IDs spreads to even more N of N terminal devices 4 and 5, creating a product sales support system in which the introduction and recommendation of product 1A spreads widely in a chain reaction.

[0026] However, if a user (customer) of terminal device 3-2 reads the two-dimensional code of introducer ID 2-1, browses online content 1C2, and selects "Purchase" 1C2a instead of "Recommend" for the product, the introducer information database 1D records the information as 1D3, and confirmation 1D4, indicated by the arrow, confirms that the parent introduction ID of the introducer to the user of terminal device 3-2 is 2-1. Furthermore, confirmation 1D5, indicated by the arrow, reveals that the parent introduction ID of that introducer ID 2-1 is introducer ID 1-1, as can be seen from table 1D2 of introducer information database 1D. Therefore, as will be explained in detail later, the server device 1B is configured to record a transaction in which the introduction fee for the user of terminal device 3-2 purchasing the product is paid to terminal device 2-1 and the user of terminal device 1-1. This is because in the product sales support system of the present invention, the chain of introductions extends to multiple levels, and it is obvious that even from a lower-level terminal device, by tracing the records in the introducer information database 1D as described above, the introducer ID and terminal device to which installment payments are to be made can be determined.

[0027] Next, the configuration and functions of the present invention will be explained in more detail. Figure 2 is a diagram showing the roles and functions of the components that make up the product sales support system according to the present invention. Here, the explanation will also cover the case where a new product 2A is added to the list of products to be introduced in the system of the present invention. The terminal device 11 held by the user (customer) has a "two-dimensional code reader" and performs the product information display upload process in the "product ID and product information setting unit" 1BA1 of the online shop content 1C or 2C for product 1A or 2A, as explained above, from a server device 1B managed and operated by the seller of the product via an Internet communication network 1N. Furthermore, thereafter, when the product introduction button 1Cb in the content 1C is pressed from terminal device 11, for example, server device 1B sets an introducer ID 1-1 for terminal device 11 in introducer information record database 1D for each product ID, such as product 1A (product ID is IA) or product 2A (product ID is 2A), as the first in the chain order, with no parent introducer ID, and stores this record as record 1D1 in introducer information database 1D shown in Fig. 1. This processing is performed by the "introducer ID registration processing unit" 1BB1 of server device 1B in Fig. 2.

[0028] Furthermore, server device 1B is provided with an "introducer ID-specific content generation processing unit" 1BB3 that uploads the introducer information data 1D1 for each product ID and introducer ID, and satellite shop contents 1C1, 1C2, etc. (content 2C1, 2C2, etc. for product 2A) set for each product ID and introducer ID, to the Internet 1N. Furthermore, server device 1B is provided with a "two-dimensional code generation and transmission processing unit" 1BB2 that generates a new two-dimensional code (QR code (trademark)) incorporating the information of the introducer information data 1D1 for terminal device 1-1 to which the introducer ID has been assigned and registered. The generated two-dimensional code is displayed as secondary code 1-1 in FIG. 1 on terminal device 1-1 via the Internet communication network 1N, and has the role and function of serving as activation information for recommending or soliciting the purchase or introduction of the product to the next product introducer (product sales supporter), for example, the owner of terminal device 2-1 or 2-2.

[0029] In this way, for example, the 2D code displayed on terminal device 2-1 can be read by terminal device 3-1 repeatedly, and a similar chain of product sales introductions can be established up to terminal device N in the chain order, greatly expanding the circle of sales support, thereby achieving an innovative configuration of the system of the present invention. In the explanation of Figure 2, terminal devices 2-1, 3-1, and N-N each have different registered introducer IDs, but otherwise have almost the same functions, thereby realizing the configuration and functions of the system of the present invention. However, here, as an example, if terminal device 3-2, which is connected to the Internet communication network 1N in the same manner as above, selects "purchase" rather than "introduce" the product, an introduction fee will be paid to terminal device 2-1, which is higher in the chain order (parent introducer ID), and terminal device 1-1, which has its parent ID. This will be described in detail later as a new embodiment of the invention.

[0030] Next, an example of the hardware configuration of an embodiment of the product sales support system of the present invention will be described. FIG. 3 is a diagram showing an example of the hardware components of the overall product sales support system of the present invention. In the product sales support system 1S of the present invention, a two-dimensional code 1Q is attached to a product 1A. Furthermore, there are a group of multiple terminal devices 1 (1 to N) such as mobile phones (smartphones) that have similar functions and are configured in hardware to process data with a "terminal communication processing unit" that has a built-in camera 301, a "two-dimensional code reading unit," a "product image display unit," a "button input processing unit," and a "new two-dimensional code display processing unit" connected to an Internet communication network 1N and enables mutual information exchange communication.

[0031] Similarly, there is a server device 1BA operated and managed by the "seller" of the product connected to the Internet communication network 1N. From here on, we will explain an example in which the system of the present invention is operated separately between the "seller's" server device 1BA and the "advertising agency's" server device 1BB, which is entrusted by the "seller" to register and manage introducer IDs and calculate introducer reward fees for the system of the present invention. In the product sales support system of the present invention, since the products concerned may be multiple and diverse, it is also assumed that there will be multiple sellers of the products handled by the system. In this case, it is better to operate the system by separating the functional roles of the server device into the server device 1BA managed and managed by the "seller" and the "advertising agency" that undertakes sales support for multiple products from each of the multiple sellers, and managing and managing the server device 1BB, so that the system can adapt to an increase in the number of target products and enable efficient operation.

[0032] The seller's server device 1BA has a "Product ID and Product Information Setting Unit" 1BA1 for posting product sales information on the online shop using the product ID of the product's product number or the JAN code (JIS standard) assigned to each product, which is a code number assigned to each product by country of origin, manufacturer, major product category, product number, etc., and also has a "Product Payment and Shipping Processing" 1BA2 function. The seller also has an "Introducer ID Registration Permission Unit" 1BA3 function, which allows the seller to restrict registration of a user (customer) as an introducer, such as by refusing registration without a prior purchase history for the product. Furthermore, the seller also has a "Introducer Reward Payment Processing Unit" 1BA4, which allows the seller to determine and change the introduction fee per product, taking into account the product's manufacturing and purchasing costs. This information is configured to be exchanged via the server device A's communication unit with terminal devices 11 through 1N and the advertising agency's server device 1BB via the Internet communication network 1N.

[0033] Furthermore, in the "advertising agency" server 1BB, a "server device B communication unit" is connected to the network communication unit 1N. The seller's server 1BA has an "introducer ID registration processing unit" 1BB1 that records the introducer's chain ranking, chain order, and parent ID and assigns an introducer ID to each introducer who has been granted permission to register an introducer ID, similar to 1D1 and 1D2 in the introducer information database 1D described above in FIG. 1. It also has a "two-dimensional code generation processing unit" 1BB2 that generates a two-dimensional code (QR Code (trademark)) by incorporating the product ID, the introducer ID, and link destination information data for the online shop content assigned to each of them. Finally, there is an "introducer ID-specific content generation processing unit" 1BB3 that uploads online shop content containing unique information for each introducer ID to the Internet. However, since this "introducer ID-specific content generation processing unit" 1BB3 mostly processes changes and settings of product information in the online shop content managed by the seller, it may be structured to be provided in the seller's server device 1BA. Next, there are the "introducer data storage processing unit" 1BB4 and the "introduction reward fee calculation processing recording unit" 1BB5, but these will be explained as other embodiments of the present invention and will be described later.

[0034] Here, we explain how the referral chain works among the terminal devices 11 through 1N in the system of the present invention. The product description screen 311 for online shop content displays the same product description information on all terminal devices in the system of the present invention. However, the "Purchase" and "Referral" selection screen 312 incorporates attribute information for the previously registered introducer ID. Therefore, when another user (customer) viewing the content (311 and 312 in Figure 3) makes the selection on their terminal device, the attributes of the terminal device that uploaded the content to the Internet communication network 1N from server device 1BA or 1BB, i.e., the introducer ID information for the terminal device described above, are transmitted to server device 1BA or 1BB via a so-called CGI command. Here, for example, when a user of terminal device 11 selects "Referral" on screen 312, a two-dimensional code generated by the "two-dimensional code generation processing unit" of server device 1BB is displayed on display screen 313. This is for inviting the next introducer in a chain reaction, and is configured to be displayed so that it can be read into the terminal device 21 of the next introducer candidate, for example.

[0035] In modern society, most people own mobile phone terminals. Mobile phones (smartphones) that connect to the Internet communication network 1N can be used as the terminal devices described above in the present system, potentially dramatically increasing the number of chain introducers for supporting the sales of a wide variety of products. Furthermore, since the product IDs are two-dimensional codes (JAN codes) that are assigned unique numbers and are attached to products widely sold in the general market, there is no need to attach new two-dimensional codes to identify products. It is expected that the number of products covered by the present system will rapidly increase without incurring additional costs. Therefore, it is anticipated that the product information data of an online shop incorporating information for each product ID and each registered introducer ID shown in Figure 1 will require a huge amount of storage capacity. Therefore, this information data can be stored in a new "cloud database" 3CD (Figure 3), connected to the Internet communication network, and the present system can be constructed to accommodate this.

[0036] Here, the operational sequence of the first embodiment of the system of the present invention will be described. Figure 4 shows an example of the sequence of the linking of introducer IDs in the system of the present invention and the generation and transmission of two-dimensional codes on the server devices of the "seller" and "advertising agency." Up to this point, the configuration and functions of the first embodiment of the system of the present invention have been explained, so the operational flow and key points of the sequence will be explained to deepen understanding. The terminal device 1 (1 of 1) reads the two-dimensional code 1Q attached to the product 1A and obtains an information link destination for the product content of the online shop, and the server device A, 1BA transmits product information 401 of the online shop content to the terminal device 1 (1 of 1).

[0037] Next, while the terminal device 1 (1-1) is displaying product information 402 (represented by 1C in FIG. 2) for the content, it selects "Introduction" 1Cb and makes an introducer ID registration request 403 for that product. The "seller's" server device A (1BA) then transmits a registration permission 404 for the introducer ID, linked to the product ID, to, for example, the "advertising agency's" server device B (1BB). The reason why the "seller's" permission is required after the introducer ID registration request 403 from terminal device 1 (1-1) via the "seller's" server device A (1BA) is that the user of terminal device 1 (1-1) is the starting point of a chain of introductions for the product, and the "seller" can determine whether the user is trustworthy enough to request a chain of subsequent introductions.

[0038] Next, for example, server device B (1BB) of an "advertising agency" generates and transmits QR code 1-1 (two-dimensional code) for terminal device 1 (1 of 1) (405), which is received by terminal device 1 (1 of 1). An example of the data structure of the QR code generated at this time is shown in FIG. 7(b), which will be described below. FIG. 7(b) is a diagram showing an example of the data structure of a QR code generated for each product ID and containing information for each introducer ID, in the product sales support system of the present invention. Data structure example 7b of the QR code generated for each introducer ID is generated with a data structure consisting of, from left to right, a URL 7b1 linking to the basic component information site of the system of the present invention, a product ID 7b2, an introducer ID 7b3, and a parent introducer ID 7b4 of the person who previously introduced the introducer.

[0039] Here, if the chain ranking number of the introducer ID is low, for example, 7-1, then based on the table of the introducer information database 1D in Figure 1, the parent introducer ID is traced back as described above, and the parent introducer ID 7b4 becomes introducer ID 6-1, and then its parent introducer ID 5-1, and then its parent introducer ID 4-1, and so on, and the QR code 7b is generated in this manner.Furthermore, if there is an introducer before that, the parent's parent introducer ID and the parent introducer ID before that are traced back to the introducer ID 1-1, which is the starting point of the introducer ID, and even if it continues, code information can be generated as long as it is within the information data configuration capacity of the QR code. The data configuration example 7b of the QR code explained above is also configured so that code information 7b1 is the site URL of the online shop content page collection of the system of the present invention, the next code information, product ID, 7b2 is its subpage URL, and the next code information, introducer ID, 7b3, can incorporate attribute information of the introducer ID corresponding to screens 312 and 313 in Figure 3.

[0040] Next, a second embodiment of the product sales support system 1S of the present invention will be described. FIG. 5 shows an example of a sequence diagram for operating the product sales support system of the present invention by installing an application for participating in the product sales support system in advance on a terminal device 1 (1 of 1). First, the terminal device 1 (1 of 1), which is the starting point of the introduction chain of the present invention system described so far, downloads and installs a "product sales support system application" 51 previously uploaded by the "seller" terminal device A, 1BA or the "advertising agency" terminal device B, 1BB to the Internet communication network 1N. The sequence diagram of FIG. 5 shows a state 501. This application 51 uses the "two-dimensional code reader" (see FIG. 3) connected to the terminal device's camera 301 to read JAN codes (JIS standard, also known internationally as EAN codes), which are product identification information widely used in the market and assigned unique code numbers for each product by country of origin. FIG. 5 shows a state 502 of product two-dimensional code reading.

[0041] Therefore, since the terminal device 1 (1-1) can identify and specify the specific designated product (the product for which a product ID is set), it inquires of the "seller's" server device A, 1BA (or the "advertising agency's" server device B (1BB)) whether the product is a specific product participating in the system of the present invention, makes a product information request 503, and obtains product information, for example, online shop content 1C or 2C with a detailed product description. In this case, there is no problem if the content 1C or 2C is transmitted from the "advertising agency's" server device B (1BB) that has been commissioned by the "seller".

[0042] Then, for example, if a user browses content 1C on terminal device 1 (1-1) and selects "Introduction" 1Cb from "Purchase" 1Ca or "Introduction" 1Cb, the user uses the CGI form function built into content 1C to input necessary information such as product ID information and the introducer's name and other personal information, and issues an introducer ID registration request 505. Next, server device A (1BA) of the "seller" receives this and determines whether or not to permit the registration. If the introducer ID for each product ID is permitted 506, it notifies terminal device B (1BB) of the "advertising agency." Then, in the next step, server device B (1BB) uses the CGI form function to generate and transmit 507 a QR code for terminal device 1 incorporating the attribute information of the introducer ID to terminal device 1 (1-1). Terminal device 1 (1 of 1) receives this QR code information data (data in which the code information of 7b described in FIG. 7 has been generated into a QR code pixel graphic), and becomes the starting point for a chain of introductions. Terminal device 2 (2 of 1) reads this data, and the next user terminal device 2 (2 of 1) then views content 1C1 incorporating the attributes of introducer ID 1-1, which was uploaded by server device A or B to the Internet communication network 1N at the same time as the registration of introducer ID 1-1. This is the sequence shown by product information display 508. Thereafter, the system of the present invention can carry out a chain of introductions in the same manner as described in the first embodiment of the invention.

[0043] As described above, the second embodiment of the present invention can identify products to be introduced by the system of the present invention by reading the JAN code (JIS standard, or EAN code overseas) that is generally attached to a wide variety of products in department stores, supermarkets, etc. This has the effect of significantly reducing the effort required to set and attach a new two-dimensional code to the product. Furthermore, because of this, the system of the present invention is expected to be able to create a chain of introductions and handle even a huge variety of target products for which sales support can be provided.

[0044] For example, a mail-order catalog containing sales descriptions of approximately 1,000 products is widely distributed in the market. At the beginning of the catalog, a two-dimensional code (QR code) 52 (or 7a2 in FIG. 7(a)) is printed, introducing the purpose of the sales support system and directing the user to install the product sales support system application 51 on a terminal device 1 (1-1). A seller or advertising agency selects, for example, approximately 100 products from the 1,000 products participating in the system of the present invention. Near the product descriptions, the seller or advertising agency prints a mark 7a1 (see FIG. 7(a)) indicating that the product is participating in the system of the present invention, along with, for example, the JAN code 7a3 or a unique product number. This information can be scanned or entered by the user's terminal device, enabling a chain of product-by-product introductions using the system of the present invention. It is obvious that the same effect can be achieved by replacing the mail-order catalog with an online shopping mall offering thousands of products, uploaded to the Internet 1N. To realize these, a database with a fairly large storage capacity is required, but this can be realized by providing the "cloud database" 3CD in FIG. 3 on a cloud-based server device connected to the Internet communication network 1N.

[0045] Next, we will explain the third embodiment of the product sales support system 1S of the present invention. Figure 4 above shows the operational sequence of the first embodiment of the product sales support system 1S, explaining up to the generation and transmission of a QR code for terminal device 1 (405). Similarly, Figure 5 above shows the operational sequence of the second embodiment of the system of the present invention, explaining up to the generation and transmission of a QR code for terminal device 1 (1 of 1) (507). Figure 6 is a diagram showing an example of an information transmission sequence for paying a referral reward to a chained introducer, as a third embodiment of the product sales support system 1S of the present invention. In the figure, the operational sequence of the third embodiment of the system of the present invention is the same from the generation and transmission of a QR code for terminal device 1 (1 of 1) (405 or 507).

[0046] The generated QR code for terminal device 1 (1-1) is displayed (601) on terminal device 1 (1-1). Next, the QR code information is read by the two-dimensional code reader via camera 301 on terminal device 2 (2-1) of the user making the chain solicitation. Terminal device 2 (2-1) then displays, for example, 1C1 or 2C1 of the linked online shop content that server device A (1BA) or B (1BB) previously uploaded to the Internet communication network 1N. This is the operational sequence known as product information display (602). For example, if the user of terminal device 2 (201) selects "introduce" in the product content 1C1, an introducer ID registration request (603) is made, which is received by server devices A (1BA) and B (1BB) and recorded as introducer information data 1D2 for introducer ID 2-1 in introducer database 1D of FIG. 1 . At this time, the introducer information data 1D2 records the product ID as 1A, the terminal device as 2-1, the introducer ID as 2-1, the chain order as 2, the chain sequence number as 1, and the parent ID as terminal device 1 (1-1). Next, server device A (1BA) or server device B (1BB) registers the introducer ID 604, and server device B (1BB) generates and transmits a QR code for terminal device 2 (2-1) 605, which incorporates URL link information to the online shop content of the product ID and is linked to terminal device 1 (1-1).

[0047] Here, as in the above, terminal device 3 (3-2) reads the QR code 2-1 displayed on the screen of terminal device 2 (2-1), and by requesting product information 606 and displaying product information 607, online content 1C2 is viewed, and when the product purchase decision 608 is made and the "Purchase" button 1C2a is pressed, product payment and product delivery notification 609 are immediately made between server device A (1BA) and terminal device 3 (3-2). In response to this, the seller's server device A (1BA) and the advertising agency's server device B exchange 610 information on payment of the product price and information on calculation of the referral fee, and as a result, in this example, server device B issues an instruction 611 to A to pay half of the total referral fee per product to the user of terminal device 2 (2-1) as the referral fee from the seller, and also pay half of the referral fee to the user of terminal device 1 (1-1) as the parent introducer, in installments. Based on this instruction, the "seller's" server device A (1BA) simultaneously sends a payment notification 612 to terminal device 1 (1-1) and terminal device 2 (2-1), and executes the payment.

[0048] Similarly, in the system of the present invention, when the introduction chain becomes multi-stage, for example, when a product is purchased from terminal device N, the introduction fee divided into introduction fee 1 / (N-1) is paid from terminal device 1 to N-1 613. As explained so far, the product sales support system of the present invention is a product sales support system that supports product sales by soliciting or introducing purchases by creating an introduction chain among many introducers related to a wide variety of products from a large number of sellers, so that with proper operation as described below, sellers, advertising agencies, and introducers all involved in the system of the present invention have the potential to make great profits.

[0049] For example, Figure 7(a) is an example of the contents of a paper tag 7a indicating the identification of a product, attached to each product, such as product 1A or product 2A shown in Figure 5. A symbol mark 7a1 of the system of the present invention indicating that the product is participating in the product sales support system of the present invention is written on the tag, and next to that is a QR code 7a2 that links to the product sales support system application 51 described in Figure 5 above, and next to that is a two-dimensional code (JAN code) 7a3 that uniquely identifies the product, and above that is a sales price display 7a4 of the product.

[0050] If a product with such a paper tag is found among the many products on display in a department store or various storefronts, the user (customer) can have the terminal device (cell phone, smartphone) they own read the two-dimensional code, perform the operation sequences 501, 502, and 503 of Figure 5, and easily register the introducer ID for that product. This allows other users (customers) to continue the chain of introductions described above, and subsequently increase the number of introducer ID registrants with lower chain ranks and chain numbers than themselves, motivating participants to earn larger introduction fees, thereby operating the system of the present invention.

[0051] In this case, the seller or advertising agency can use the JAN code (JIS standard, sometimes called the EAN code overseas) for the two-dimensional code 7a3, which is generally assigned uniquely to most products on the market. Furthermore, by making efforts to widely publicize the mark 7a1, the number of products and users (customers) participating in the system of the present invention can be dramatically expanded. Furthermore, if the introduction chain of the system of the present invention is carried out over the Internet, the mark 7a1 display or text can be linked from within the content of an online shop to launch the product sales support system app. The target product can also be linked from the image or text data of the product name within the app, allowing viewing of the content 1C1, 1C2, or 2C1 and 2C2.

[0052] (2) In the system of the present invention, if the chain ranking when an introducer ID is registered by a terminal device is high (here referred to as low ranking), such as 5th or 6th, and if the introducer ID is registered and then a product is purchased on the content page, publishing an operational rule such as raising the chain ranking of the introducer registration ID or making it the starting point 1 can be useful in motivating the introducer of the product to become a purchaser. In addition, to prevent an introduction chain that results in a very low chain ranking, for example, if a terminal device makes a registration request 614 for an introducer ID that is ranked 7th in the chain ranking, server device A or B can deny registration of the introducer ID 615 and send reply information 616 such as "Please select another product" or "Select to purchase this product, then select introduction and register the introducer ID. Your chain ranking will rise to 1st," thereby eliminating introducers who have little desire to introduce the product.

[0053] Next, other embodiments of the product sales support system 1S of the present invention will be described. FIG. 8 illustrates how a participant in the sales support system of the present invention creates a new online shop. The "seller" server device 1BA or the "advertising agency" server device 1BB uploads an online shop 81 for multiple products participating in the system of the present invention to the Internet communication network 1N. The online shop 81 displays product sales content 811 to 813 participating in the system of the present invention, and includes a marker 7a1 indicating participation in the system of the present invention, a two-dimensional code 1-1 incorporating the introducer ID attribute, and a means for selecting "Purchase" or "Introduce" 81b. Additionally, product content 814 not participating in the system of the present invention is also displayed.

[0054] Here, a user newly participating in the system of the present invention can browse the online shop 81 on their terminal device, select product content 811, 812, or 813, read the two-dimensional code 1-1 for each product content, or select "Introduction" 81b, and register the respective introducer IDs to create a new online shop 82 displaying the product description content. At this time, the product content 822 in the newly created online shop 82 displays a two-dimensional code 2-1 incorporating attribute information of the introducer ID and a "Introduction" means (button) 82b to invite the next introducer. However, if the product content 821 and 822 could be configured to selectively display only the means (button) 81a for deciding to "purchase" without requiring a next introduction chain, an even more flexible new online shop 82 could be created.

[0055] With this configuration, a user wishing to register a new introducer ID to participate in the system of the present invention can browse an online shop 81, which has been created by a "seller" or "advertising agency" and previously uploaded to the Internet communication network 1N, displaying multiple products. The user can then easily and time-savingly create a new online shop 82 on the Internet communication network 1N by scanning the two-dimensional code 1-1 of a desired product with the user's terminal device or selecting "Introduction" 81b from the browser. In other words, for example, using a mobile terminal device (smartphone) owned by most modern working adults, an online shop can be easily and effortlessly created, where users can sell and introduce various products and earn referral fees or points for specific purchases. When a product is "purchased" in the online shop, the seller handles all of the following: displaying the product in the online shop, expanding the product lineup, performing maintenance, settling the product price with the purchaser, and shipping the product. Only the referral fee for the product is transferred to the user of the mobile terminal device. This creates a new distribution model, which is expected to have significant industrial benefits.

[0056] Sellers or advertising agencies of various products using the system of the present invention may have multiple and diverse market reputations and business situations. For example, as described above, there may be cases where a chain of introductions is widespread, and introducer information data 1D1 and 1D2 by product ID, in which introducer IDs are registered by chain order and number, must be deleted due to the seller's or product's circumstances. Furthermore, a sudden accident, such as a breakdown of server device A (1BA) managed and operated by the seller or server device B (1BB) of the advertising agency, resulting in the loss of introducer information data 1D1 and 1D2, may occur.

[0057] Therefore, the introducer information database 1D for each product ID, as explained in Figure 1 above, is made into a cloud database 3CD using a distributed memory ledger (blockchain) that can be accessed from multiple related terminal devices related to the system of the present invention and can retain memory.For example, many sellers for each product ID can successively register new introducer IDs, add to and change the parent ID records, but cannot tamper with the data.Furthermore, even in the event of a sudden loss of some of the data in the introducer information database 1D for a specific product ID, since it is shared by many "sellers" and others, there is a means to easily restore it, making it easy to respond to repairs.

[0058] Furthermore, by making the contents of the cloud database 3CD available to many users who have introducer IDs linked to each product ID, and allowing each user to check their own referral chain ranking and referral reward fee, the system of the present invention can be constructed to enhance the competitive spirit of each user while maintaining fairness, and the product sales support system of the present invention is expected to have a significant industrial impact.
