Description

  The present invention relates to an information display device and an information display system that perform transmission and reception of information between computers by information communication via a network, and a program, and in particular, by displaying common information between displays of computers that perform information communication, The present invention relates to an information display device, an information display system, and a program that make it possible to quickly and reliably make decisions in electronic commerce and electronic conferences without causing errors.

  In recent years, with the spread of communication systems and communication environments typified by the Internet, cases in which various commercial transactions, communications, information exchange, etc. are performed by transmitting and receiving information on the network are increasing.

  For example, electronic commerce (e-commerce) has the advantage that it can save time and effort to meet directly with a business partner, and can easily and quickly conduct business with a remote partner. Yes. In such electronic commerce, mutual intention confirmation necessary for buying and selling various products is performed by information communication via a computer network, and since the parties to the transaction do not meet and negotiate directly, mutual trust and In addition to problems such as the certainty of transactions, problems such as slow responses in mutual intention confirmation also arise.

  That is, when a trading party meets directly and conducts a commercial transaction, the negotiation target can be shortened because the transaction object and the transaction price can be specified in the discussion. On the other hand, in negotiations in normal electronic commerce, the seller side specifies the product and its sales price, advertises with a Web browser, etc., accepts the conditions, and the purchaser who wishes to purchase the Web browser or electronic When an offer for purchase is made by e-mail, and the seller confirms the offer for purchase, an e-mail for confirmation is sent, but the time between obtaining this confirmation e-mail varies. is there. Therefore, the purchaser is caught in anxiety about whether or not the purchase is possible during such an uncertain time. Furthermore, even if the purchaser wishes to negotiate the transaction details and conditions, after making a proposal for negotiation, it is necessary to wait for contact from the seller, resulting in a so-called time lag.

  Therefore, conventionally, in order to eliminate such a time lag in electronic commerce, it has also been proposed to negotiate using chat in electronic commerce. For example, in Patent Document 1 (Japanese Patent Application Laid-Open No. 2002-117254), on the Web screen in the virtual store on the Internet, the product configuration and display layout at each sales floor are substantially matched with the actual store, thereby substantially A virtual store on the Web having the same structure as the structure is constructed, and the customer can enjoy commercial transactions on the Web such as browsing or purchasing products or providing various business services with the virtual store in the same manner as an actual store. A virtual store sales system on the Web has been proposed, and it is proposed to use means such as chat via the Internet, Internet telephone, Internet TV telephone, etc. as means for contacting customers and operators.

  Patent Document 2 (Japanese Patent Laid-Open No. 2008-77527) discloses a net auction system for bidding by chat, an exhibitor message transmitted from an exhibitor terminal, and a purchase request transmitted from a purchase requester terminal. A commercial transaction system has been proposed that negotiates the price of an exhibit while trying to communicate among the three parties by receiving and displaying the participant message and the browsing participant message transmitted from the browsing participant terminal as a chat message.

  Further, in order to perform e-commerce while maintaining the authenticity of the quote, in Patent Document 3 (Japanese Patent Laid-Open No. 2002-63413), in electronic commerce, a buyer inputs a quote request to a viewed web page. A transaction method, transaction system, and terminal that accepts a request for quotation, presents a quotation on a web page that only the buyer can view, places the buyer to view it and places an order on the web page, and the seller accepts the order. And recording media have been proposed.

  Furthermore, a web conference system using real-time streaming has been proposed as a system for distributing information to a plurality of users in two-way communication. For example, Patent Document 4 (Japanese Patent Application Laid-Open No. 2004-165946) is a WEB conference system connected to a plurality of terminals via a network, and delivers speech information, chat information, and display material information to each terminal. At the same time, it is proposed that speech information and chat information are associated with materials and stored as time series information as minutes. In this document, it is also proposed to display the materials used for the conference on the whiteboard on the screen of all participants.

JP 2002-117254 A JP 2008-77527 A JP 2002-63413 A JP 2004-165946 A

  As described above, as shown in Patent Documents 1 and 2 in the past, when performing electronic commerce, it is not possible to communicate between the seller and the purchaser using chat or email. It was proposed. Among these, in the method of performing the chat, all the negotiations must be entered in the chat, which is not a little bothersome for both transactions. Also, in the method of using e-mail, there is no guarantee that the other party of the commercial transaction will reply the e-mail immediately, so even if it is a little negotiation, you have to bother sending the e-mail and waiting for the reply There was annoyance.

  Therefore, the present invention displays only the information that is important in commerce and is desirable to be confirmed visually, on both sides (transaction parties) in real time, and changes the contents at any time according to negotiations between the parties. The first task is to provide an information display device, an information display system, and a program capable of proceeding with a commercial transaction while visually confirming the above.

  In the WEB conference system proposed in Patent Document 4, minutes are created by associating speech information and chat information with materials, and materials used for the conference are displayed on the screens of all participants. However, what is displayed in real time is a document that has been created in advance, and the minutes are simply stored associating speech information and chat information with the document.

  Therefore, in the present invention, matters that occur during the progress of the conference can be presented to all participants at any time in real time, and necessary changes and additional information are displayed for the presented items, and the contents after the change are displayed. A second problem is to provide an information display device, an information display system, and a program that can be displayed in real time and visually confirmed by all participants.

  Furthermore, in order to ensure the certainty of transactions in commercial transactions, important agreement items in commercial transactions and important agreement items in conferences may need to be confirmed later, so it is desirable to record them.

  Accordingly, the present invention provides an information display device, an information display system, and a program capable of storing various important matters such as important matters in such commercial transactions and agreement items accumulated at meetings. Let's assume three issues.

  In order to solve at least one of the above-mentioned problems, the present invention enables visual confirmation of matters that need to be confirmed among parties performing information communication, particularly important matters. Provided are an information display device, an information display system, and a program capable of changing matters and displaying the contents after the change in real time to confirm mutual intentions.

  That is, in the present invention, in order to solve at least one of the above-mentioned problems, an information display apparatus connected to an electronic terminal equipped with a display apparatus via a network, at least connected via the network A communication means for performing information communication with the electronic terminal; and an input means for inputting first information to be transmitted to the electronic terminal connected via the network; and another electronic device connected via the network. Display block generating means for generating a display block for displaying the first information in the display device of the terminal, and the first information displayed in the display block partitioned in the display device in the other electronic terminal are changed. Provided is an information display device characterized by comprising display content changing means.

  The display block generation means is connected to the information display device through a network, and other information such as estimate information and minutes at the conference is displayed on the display device (display, etc.) of the other electronic terminal. A display block for generating the display block is generated, and a drawing command for the display block is transmitted from the information display device to another electronic terminal. A display block to be drawn on another electronic terminal can be newly generated or displayed as a separate frame in a display block already displayed. For example, when a graphical user interface that displays information in a window format is drawn on a display device (such as a display) of the other electronic terminal, the display block is displayed as a separate window or in the displayed window. Can be displayed as a separate frame.

  The display block generation means is configured to transmit data in a format that can be drawn and displayed by a program in the other electronic terminal in order to draw the display block on the display of the other electronic terminal. For example, when various browsers (programs) are operating in the other electronic terminal, various types of data such as data described in an HTML format that can be displayed by the browser are transmitted.

  The display content changing means, when changing, adding, or deleting the first information displayed on the display block, displays the first information after the change, addition, or deletion in the display device in another electronic terminal. It is for displaying quickly in the display block divided into two. For example, when the display information changing unit is changed, added, or deleted from the first information by the information input from the input unit in the information display device, the first information after the change is changed to the other information. Command to reload the first information or display block display (that is, a request to reload the information displayed in the display block) to the other information terminal for display on the electronic terminal Command information (hereinafter also referred to as “drawing command”). Such a drawing command can also be configured to be issued when a change, addition, or deletion to the first information is performed in the information display device.

  According to the information display device configured as described above, the information (first information) necessary for mutual mutual confirmation of the information communication between parties involved in information communication, such as an estimate in a commercial transaction and minutes of a meeting. ) Can be generated and displayed in the display device of the other party, thereby enabling communication by various means while visually confirming. Furthermore, when the first information needs to be changed in the communication, the change can be immediately reflected, so that negotiations can proceed as if the niece is directly meeting.

  The information display device further includes recording means for recording one or more format information defining the layout of the display block, and the format specified by the input means when generating the display block in the display block generating means. It is also possible to read the information and generate a display block for displaying the first information in the display device of another electronic terminal connected via the network based on the format information.

  The format information is a record of the size, layout, display items, etc. of the display blocks to be displayed on the display device of another electronic terminal that is transmitting information with the information display device. Two or more are prepared. For example, it is possible to hold form information for displaying the minutes (that is, the first information) in the electronic conference and form information for displaying the estimate contents in the electronic commerce. Furthermore, even if it is form information for displaying the minutes, even if it is a display block that displays the contents of the estimate in electronic commerce, or the display form of the display block displayed according to the type and content of the meeting The display style can be changed depending on the contents of the product or service. Of these various types of format information, which format information is to be used is designated from the input means provided in the information display device, and in addition to the calculation or extraction in the information display device depending on the content to be transmitted. It can also be configured to be selected by processing. For example, content items to be transmitted and received can be displayed in a menu, and the style information associated with the menu can be read depending on which menu is selected.

  According to the information display device configured as described above, it is possible to select the optimal form layout according to the scene in which the information display device is used, thereby enabling quick communication between the parties. it can.

  According to the present invention, in order to solve at least one of the above-described problems, information communication is performed with each other via a network, each of which is composed of two or more electronic terminals each having a display device. Any one of the information display devices according to the present invention is used as at least one of the electronic terminals that performs the above-described processing, and the display block generating means included in the electronic terminal using the information display device is the electronic terminal. Provided is an information display system for displaying input first information with the same contents in a display block generated on a display device in another electronic terminal performing information communication with each other.

  In other words, the information display system includes the information display device according to the present invention and two or more electronic terminals connected to the information display device via a network. These information display devices and electronic terminals are often configured using computers, and any communication method can be used for the connection between the computers as long as information can be transmitted from one computer to another. Preferably, a communication method capable of bidirectional communication is used. Such information transmission / reception can be performed via a server installed on the network, but it is desirable to adopt a peer-to-peer (Peer to Peer) network configuration in which an unspecified number of computers are connected to each other. This is to reduce the load on the server and promptly display the transmitted information (first information, etc.).

  In the information display system, any electronic terminal performing information communication generates a second information display field for displaying second information transmitted and received in both directions, separately from the block for displaying the first information. It is desirable to provide two information display field generation means.

  That is, in addition to the display block for displaying the first information, the second information display field is generated in order to generate a second information display field for discussion such as negotiation and discussion between the parties performing information communication. Column generating means is provided. The first information is information necessary for determining the contents of the commercial transaction, such as information shown in a quotation, a purchase order, an invoice, an invoice, etc. in a commercial transaction, or information that needs to be stored, On the other hand, the second information widely includes information other than the first information. The first information is information transmitted from the information display device to another electronic terminal, and the second information can be positioned as information transmitted / received bidirectionally. For example, in electronic commerce, the negotiation information such as the price, quantity (or time), delivery date, etc. of the goods and services to be traded is the second information, and an estimate, purchase order, delivery note, The information shown on the invoice becomes the first information.

  Further, when the information display device is used for an electronic conference, the second information is information such as opinions exchanged at the conference and various materials used at the conference, and the first information is the conference. This information is fixed information, especially information that is stored as minutes and briefly shows the contents of the meeting.

  The first information is displayed at least in a display device of another electronic terminal that is in information communication with the information display device, preferably on a display device of the information display device in a predetermined form format layout. The second information is displayed in a format in which information can be exchanged from both sides, such as chat, which is a communication means on a computer network.

  In the information display system, at least one of the electronic terminals that perform the information communication includes the first information displayed in the block generated by the display block generating unit and the first information changed by the display content changing unit. It is desirable to provide display information recording means for recording at least one of the change histories.

  The display information recording means records the first information finally identified or the first information including the change history so that the contents of information communication can be confirmed later, usually a computer Can be recorded in a table format, database format, file format, or the like. In addition, the display information recording means is preferably provided with an appropriate index such as time, information communication partner, information communication content, etc. in order to facilitate later retrieval. In addition, the storage location of the information in the display information recording unit is the storage unit included in the information display device, the storage unit of another electronic terminal that performs information communication with the information display device, or the information display device and the other electronic device. The information can be stored in the storage means of the terminal, and the information can be stored in the storage means provided in the external server device installed on the network.

  By providing such display information recording means, the first information can be reliably held in the case of a commercial transaction, and the minutes can be securely held when used in a meeting.

  And in this invention, in order to solve at least one of the said subject, the display which partitions and produces | generates the block which displays 1st information on the display apparatus of the other electronic terminal connected to the computer via the network A program for executing a block generation step and a display content change step for changing first information displayed in a block partitioned in a display device in the other electronic terminal is provided.

  By introducing such a program into a computer connected to a network, the introduced computer can function as an information display device. In providing this program, the program can be distributed not only on a recording disk or a portable memory but also in a download format using a network.

  The information display device, the information display system, and the program described above are used for information communication, particularly when it is desirable to visually check important information, but particularly for electronic commerce. desirable. This is because in electronic commerce, the contents of products and services that are subject to transaction vary, and the consideration for offering varies, as well as the delivery dates (delivery dates), which are different for the parties involved. This is because negotiation is indispensable to determine the optimal transaction content, and it is desirable to conduct the negotiation while visually confirming the transaction content. In the information display device according to the present invention, when changing the transaction content such as the estimate content by negotiation, the display content changing means promptly changes the change content in a so-called real time without causing a time lag. Because it can be presented to the other party, you can negotiate as if you are actually doing business transactions.

  Thus, in the case of an information display device specializing in commercial transactions, it is an information display device connected via an electronic terminal equipped with a display device via a network, and at least a demand connected via the network. Communication means for performing information communication with the customer side electronic terminal, and input means for inputting estimate information to be transmitted to the customer side electronic terminal connected via the network, and further via the network Display block generating means for generating a display block for displaying the estimated information as the first information in the display device of the connected consumer-side electronic terminal, and a partition in the display device of the consumer-side electronic terminal It is possible to provide an information display device characterized by comprising display content changing means for changing the estimated information displayed in the displayed block.

  Further, when the information display device is used for electronic commerce, the information display is performed so that negotiation between the provider and the consumer can be performed directly by second information such as chat or by telephone. The device may have a function of reserving a negotiation start time. For example, the information display device can hold the transaction negotiation schedule information, and can write the reservation information transmitted from the consumer side electronic terminal into the transaction negotiation schedule information. Such reservation information transmitted from the electronic terminal on the consumer side can be transmitted to a WEB site on the Internet in addition to an electronic mail format. Further, in order to clarify such negotiable time in the information display device and inform the consumer, the information display device provides the negotiable time information to other electronic terminals connected via the network. In addition, an operation schedule providing means can be provided. The operation schedule providing means can be configured to display a time zone in which a commercial transaction can be negotiated on a web page on the Internet described in an HTML format or the like in a time table format and manage the time zone. . For example, when the operating time in the electronic terminal (that is, the information display device) on the provider side is clearly specified, and the negotiation is already in progress with the electronic terminal on the other consumer side within the operating time, A message or the like requesting contact after the negotiation is completed can be held as access information or the like. Such holding of access information can also be acquired as an access log in the WEB page.

  When the information display device is used for commercial transactions, the information display device is visually displayed on the provider-side electronic terminal (that is, the information display device) and the consumer-side electronic terminal display device as described above. In addition to the estimated information confirmed by each electronic terminal, it is possible to secure the objectivity of the estimated contents by holding it in the commercial transaction management device as an external server connected to the Internet. it can.

  In other words, regarding the commercial transaction exchanged between the provider and the consumer, the safety of the commercial transaction is ensured by the fact that the third party manages the fact that it is committed to actually provide the transaction object.

  Such a commercial transaction management apparatus is a commercial transaction management apparatus in which a provider-side terminal and a consumer-side terminal to be traded are connected via a network, and in response to a request from the provider-side terminal, a consumer-side terminal A transaction number giving means for giving a transaction number attached to transaction information including the transaction target and its transaction volume and transmitting the transaction number to the provider side terminal, and a transaction target transmitted from the provider side terminal Transaction information comparison means for comparing the transaction information including the transaction volume with the transaction information transmitted from the consumer side terminal and the transaction information including the transaction volume, and the comparison result in the transaction information comparison means Thus, when a comparison result indicating that both are the same is obtained, a transaction information storage unit that stores both transaction information can be provided.

  The transaction number assigning means is a code (including a symbol and a number) that is uniquely assigned for each of a plurality of business transactions that are traded between a plurality of provider-side terminals and a plurality of consumer-side terminals. This is to identify the transaction.

  The transaction number is given for each transaction information, and the transaction information is positioned as information including at least information for specifying a transaction target and the transaction volume. The target of the commercial transaction managed by this business transaction management device (transaction target) is not only the transaction form for transferring the product (whether it is paid or free), but also the lending of the product (whether paid or free), Includes transaction forms that provide services.

  Further, the transaction volume for these transaction targets can be defined for each mode of commercial transaction. For example, in the transaction mode for transferring a product, the transaction volume is information indicating the transfer quantity of the transaction target. Yes, in the transaction form for lending goods, the transaction amount is information indicating the loan amount of the loaned object, and in the transaction form for providing services, the transaction amount is the provider. It is possible to use information indicating the amount of time for providing the service or the quantity of goods for providing the service. In particular, if an example of a business form that provides services is provided, the available time of a provider (doctor or beautician) in the medical industry or beauty is used as the transaction volume, or the number of chair seats in the beauty salon is handled as the transaction volume. Can do.

  In particular, when the transaction information is quote information of a commercial transaction, the transaction number assigning means assigns an estimate number attached to the estimate information transmitted from the provider side terminal to the consumer side terminal, and The number is transmitted to the provider side terminal, and the transaction information comparing means compares the sameness between the estimated information transmitted from the provider side terminal and the estimated information transmitted from the consumer side terminal. The information storage means stores both pieces of estimated information when both are the same. Such estimate information can include, for example, information for specifying the transaction target, as well as information for specifying the transaction volume, price, delivery date, and the like.

  According to the commercial transaction management device configured as described above, the commercial transaction management device positioned as a third party holds transaction information (for example, estimate information) determined between the parties, so that the commercial transaction based on the transaction information can be performed. When any problem occurs at the time of execution, it is possible to quickly know whether there is a problem in either the provider or the consumer. Furthermore, the transaction parties exchange transaction information such as quotations with the in mind that the contents of the transaction are stored in a third-party transaction management device. Can be realized.

  In addition, the information display device includes a transaction amount allocating unit that allocates the inventory amount owned by the information to the estimated content when finalizing the estimated content in the negotiation of the commercial transaction, and by securing the actual transaction amount in advance, It is also possible to ensure the safety of transactions.

  This means for allocating the amount of transaction is to secure the amount of the transaction when the transaction content is confirmed earlier in electronic commerce and prevent it from being diverted to the subsequent transaction. Can be secured for the transaction volume. For example, the transaction volume allocation means subtracts the transaction volume determined by the transaction from all the remaining volume for the transaction object held by the provider, and, among all the remaining volume for the transaction object held by the provider, It is conceivable to attach a code such as a flag to the remaining amount for which the transaction is confirmed and associate it with the confirmed commercial transaction.

  According to such a commercial transaction management apparatus, since a transaction target is reliably ensured for a commercial transaction that has been once confirmed, it is possible to eliminate anxiety regarding commercial transactions among consumers.

  However, in such a commercial transaction management device, even after the transaction amount is allocated to the transaction information determined by the transaction amount allocation means, the determined transaction information (for example, the estimate content) is discarded if both parties agree. It can be configured to be possible. At that time, in order to prevent the transaction information determined by impersonation from being discarded, the consent of the customer to “discard” also requires the customer to be given an encryption key or an electronic signature. It is desirable to do.

  And in the said commercial transaction management apparatus, with respect to a provider side terminal, the transaction number provision means which provides the management number of the transaction information transmitted to a consumer side terminal, the transaction information transmitted from the said provider side terminal, It is desirable to provide a transaction information comparing means for judging the identity of transaction contents in transaction information transmitted from the consumer side terminal.

  That is, in the commercial transaction management device, a transaction number for the transaction party and the commercial transaction management device to manage the transaction information is assigned, and the transaction information exchanged by the transaction party is managed using this transaction number as an index, and the transaction content This is to check whether there is no mistake. By managing the transaction contents even in a commercial transaction management apparatus positioned as a third party, the transaction parties can conduct commercial transactions with peace of mind.

  Further, the present invention provides an electronic commerce system capable of performing electronic commerce safely and securely with the same contents as those actually met and negotiated using the information display device and the commerce management device described above.

  That is, it is an electronic commerce system that conducts commercial transactions by electronic commerce, and a consumer side terminal that transmits and receives information for purchasing a transaction target by electronic commerce and a provider side terminal that transmits and receives information for providing the transaction target by electronic commerce A terminal device, and a commercial transaction management device that manages transaction information transmitted and received between the provider side terminal and the consumer side terminal, and the information display device according to the present invention is used as the provider side terminal, This is an electronic commerce system in which the commerce management device is used as a commerce management device.

  In the commercial transaction management system, the provider side terminal includes transaction information presenting means for presenting transaction information with a first encryption key to the consumer side terminal, and the consumer side terminal is a consumer It is desirable to provide transaction information confirmation means for receiving and decrypting the transaction information transmitted from the terminal on the side and transmitting it to the commercial transaction management apparatus with at least one of the second encryption key and the electronic signature.

  Transaction information in this embodiment includes transaction information exchanged prior to execution of a commercial transaction, such as information described in a general estimate (information such as transaction target, transaction quantity, transaction price, transaction deadline, etc. After confirming the estimated information transmitted from the provider side terminal with the consumer side terminal and approving or confirming the written information, the second encryption key and the electronic signature are added to this. Any one is attached and transmitted to the commercial transaction management apparatus. As a result, the transaction management apparatus can know the transaction details approved or confirmed on the consumer side, and can thereby know the transaction details determined between the parties.

  When the information display device is used as a provider side terminal in electronic commerce, the information display device can also provide a virtual store that opens on the network. Such a virtual store can be provided as a “two-dimensional Web store” expressed by two-dimensional image data or the like, or a “three-dimensional Web store” expressed by three-dimensional data such as a polygon. On the consumer side, 2D Web stores can be viewed with a widespread ordinary Web browser, and 3D Web stores can browse the metaverse (electronic 3D space) represented by polygons. A browser (hereinafter referred to as “3D browser”) is used. This 3D browser can provide a communication function in addition to realizing a walk-through display by reading 3D world data expressed by polygons from a network.

  In this case, the information display device can perform maintenance of a two-dimensional Web store or a three-dimensional Web store. In this maintenance, the maintenance related to the two-dimensional Web store only includes design customization of the two-dimensional Web store, page customization, addition of words, etc., which can be performed from a Web browser (2D browser). Maintenance related to only the 3D Web store includes customization of the terrain in the metaverse, layout of buildings / furniture / furniture, product display, etc., which can be performed from a browser capable of displaying 3D data. And maintenance related to both 2D Web stores and 3D Web stores include, for example, store information setting (store name, description, store category, etc.), store clerk registration, etc. Can be done from a web browser.

In addition, the information display device in the above case operates as a product management business in the operation of a virtual store, product registration processing and image registration processing as sales and order management business, order history management, results aggregation / output Processing as customer management business, customer registration processing, search processing, editing processing, customer response business, real-time estimate presentation processing, history management processing, inquiry response processing as reservation management business, reservation search processing, registration It can be configured to provide processing and editing processing.

  Further, when the information display device is used as a provider-side terminal in electronic commerce, a product image held by the information display device may be read and displayed in an estimate displayed on the consumer-side terminal. it can. That is, in many cases, the image data for use in the product description Web page is stored in the information display device, and can be copied and stored in the data area for the estimate.

  The commercial transaction management apparatus in the electronic commercial transaction system can be implemented by introducing the following program into a computer, for example.

  That is, on the computer to which the provider side terminal and the consumer side terminal are connected via the network, in response to a request from the provider side terminal, the transaction information including the transaction target and the transaction volume is sent to the consumer side terminal. A transaction number giving step for giving a transaction number attached when transmitting to the provider side terminal and transmitting the transaction number to the provider side terminal, transaction information including the transaction target and the transaction volume transmitted from the provider side terminal, A comparison between the transaction information comparison step for comparing the identity of the transaction object transmitted from the consumer side terminal and the transaction information including the transaction volume, and the comparison result in the transaction information comparison means that they are the same. When a result is obtained, it is a program for executing a transaction information storage step for storing both transaction information.

  According to the present invention, when performing information communication between computers, a display block can be displayed on the display device of the other electronic terminal by an operation from one of the electronic terminals such as a computer, As a result, smooth communication and negotiation can be performed based on the information displayed in the block.

  In particular, if the information displayed in the display block is information used in electronic commerce, such as quotation information, negotiations can proceed while checking the information, and changes in quotation information in the negotiations are reflected immediately. Since it can be displayed on the consumer side terminal, etc., it is possible to conduct business transactions in the same manner as when actually visiting a store or the like and negotiating directly.

Further, in FIG. 1, as a matter of course, in the actual system, there are a plurality of customer side terminals 30 and provider side terminals A (40A) and B, and this is shown in a simplified manner in this figure. There are only.

  These components are all configured using a computer, and can be configured as a hardware configuration as shown in FIG. 2, for example.

  Specifically, the computer 800 constituting the central server 10, the credit server 20, the consumer side terminal 30, the provider side terminal A (40A), and the provider side terminal B (40B) is as shown in FIG. , CPU 801, memory 802, audio output device 803, network interface 804, display controller 805, display device 806, input device interface 807, keyboard 808, mouse 809, external storage device 810, recording medium drive device 811, recording medium interface 812, And a bus 813 that connects these components to each other.

  The CPU 801 executes each program under the control of an operating system (hereinafter referred to as “OS”) and controls the operation of each component of the computer 800, and the central server 10, the credit server 20, and the customer side terminal 30 described later. Each function of the provider side terminal A (40A) and the provider side terminal B (40B) is exhibited.

  The memory 802 is generally composed of a ROM (Read Only Memory) that is a nonvolatile memory and a RAM (Random Access Memory) that is a volatile memory. The ROM stores a program that is executed when each function described later in the commercial transaction management system according to the present embodiment is performed. The RAM stores a function or process in each computer that is executed by the CPU 801. In addition, a program for realizing it and data used during the execution of those programs are stored.

  The external storage device 810 is, for example, a storage device such as a hard disk drive (HDD), in which a program and data for executing processing to be described later are recorded. Loaded into the RAM. Storage means for storing programs for performing various processes, various data, and the like corresponds to the external storage device 810.

  The recording medium driving device 811 accesses a recording surface of a portable disk type recording medium 830 such as a CD (Compact Disc), an MO (Magneto-Optical Disc), or a DVD (Digital Versatile Disc), and records on the recording surface. It is a device that reads the recorded data. The recording medium 830 can also record various programs and data to be described later.

  The audio output device 803 is a device that outputs audio, such as a speaker, and the network interface 804 is an interface for connecting to various networks 820 such as the Internet and Ethernet (registered trademark).

  The display controller 805 is a dedicated controller for actually processing a drawing command issued by the CPU 801. The drawing data processed by the display controller 805 is once written in the graphic memory, and then displayed on an LCD or CRT as a display device. Output to the configured display 806.

  The input device interface 807 receives a signal input from the keyboard 808 or the mouse 809 and transmits a predetermined command corresponding to the signal pattern to the CPU 801. The keyboard 808 and the mouse 809 are connected to the CPU. Necessary for giving a predetermined command.

  A program for realizing (or constructing) the commercial transaction management system according to the present invention is transferred from a predetermined server on the network to the external storage device 810 via the network 820 and the network interface 804 as another distribution form. It can be stored or executed directly. The program stored in such a route is loaded into the RAM of the memory 802 and executed at the time of execution, as described above.

  The recording medium interface 812 is connected to a portable memory type recording medium 840 including a semiconductor memory (for example, a flash memory) such as a USB memory, an SD memory, or a memory stick through a connection terminal or the like, and data recorded therein is transferred. It is a reading device. As with the disk-type recording medium 830, the recording medium 840 can store a program for realizing the commercial transaction management system according to the present invention.

  In the computer having the above-described configuration, particularly with respect to the consumer side terminal 30, the provider side terminal A (40A), and the provider side terminal B (40B), for example, a connection with a computer device generally marketed as a personal computer It can be configured using possible peripheral devices.

  Next, each function and holding of the central server 10, the credit server 20, the consumer side terminal 30, the provider side terminal A (40A), and the provider side terminal B (40B) having the hardware configuration as described above. The data to be performed will be described with reference to FIG.

  In particular, in the present embodiment, an example of an electronic commerce system that supports a commercial transaction in a mode of transfer of a product is shown in which a transaction target is a product. And the example at the time of implementing the transfer at the time of implementing transfer of goods as transaction information in such a commercial transaction and performing an ordering process based on this estimate is shown.

  In the configuration shown in FIG. 1, the central server 10 functions as a commercial transaction management device, that is, the provider side terminal A (40A) or the provider side terminal B (40B) as an information display device, and the information display device. It functions as a device for confirming or approving the contents of electronic commerce exchanged with the customer side terminal 30 as another electronic terminal that performs information communication, particularly the contents of estimated information. In addition, the central server 10 has a function for managing whether or not a user can use this system when performing electronic commerce using this network system, and commerce between users (that is, between a provider and a consumer). And a function for issuing a transaction ID when confirming transaction information such as a quotation and a function for storing the confirmed transaction information.

  The central server 10 having such a function holds user information (synonymous with “user data”) in order to manage whether or not the user is a user. In order to manage the user information, as shown in FIG. 7B, at least the user code is a primary key, and further accompanying information such as a company code, a user name, an email address, an account ID, and a password Are stored in a storage means (such as an external storage device 810). Such user information can be held differently depending on whether it participates as a provider or a purchaser.

  In addition, the central server 10 receives transaction information (synonymous with “transaction data”) such as an estimate exchanged between the provider side terminal 40 and the receiver side terminal until ordering / ordering processing and settlement are performed. Data holding means for holding is provided. Such data holding means can be provided with, for example, a table, file, or database in which information about items as shown in FIG. 7A is recorded in the storage means of the computer constituting the central server. In particular, in the example shown in FIG. 7A, with the slip code as the primary key, the store code and customer code as the transaction parties, and the product name, product code, unit price, and quantity information for specifying the transaction content are retained. Further, it is possible to record a delivery destination code that can be used in actual ordering / ordering processing, etc., and to record a company code. Here, the store code and the customer code can correspond to the user code in the user data, and the slip code can be a code corresponding to an estimate number in the processing described later. Further, when creating the transaction data, information indicating transaction details (for example, information such as product name, product code, unit price, quantity, etc.) can be separately formed as transaction details data.

  Then, the central server 10 holds a table, file or database for storing the confirmed transaction information in the storage means which is a component thereof. Specifically, for example, as shown in the purchase history data in FIG. 7E, the purchase history code is used as a main key, and transaction information associated therewith, such as a company code, purchase date, slip code, store code, user, etc. Code, total amount, billing amount, etc. can be recorded. In particular, the transaction content can be easily confirmed by referring to the transaction data based on the slip code.

  Then, in response to a request from the provider side terminal 40, the central server 10 is given a transaction number (such as an estimate number) for attaching to transaction information (for example, estimate information) sent to the consumer side terminal 30. And the comparison is made with the transaction information transmitted from both the provider side terminal 40 and the consumer side terminal 30. A program for executing a process for storing the transaction information is introduced.

  Further, the credit server 20 determines a credit in response to a request for credit judgment for the consumer transmitted from at least one of the provider side terminal 40 and the customer side terminal 30, and the judgment result of the credit is The data is transmitted to the provider side terminal 40 via the consumer side terminal 30 or directly. As the credit server 20, a credit judgment device operated in a credit company, a credit guarantee company, a bank, or the like can be used.

  The provider side terminal A (40A) and the provider side terminal B (40B) (these are also simply referred to as “provider side terminals 40”) and the consumer side terminal 30 can be connected to a network such as the Internet. The configuration includes a configuration in which the provider side terminal 40 and the consumer side terminal 30 can exchange information for a commercial transaction with each other via a network.

  The provider side terminal 40 is independently operated and managed on the provider side, and at least a display for generating a display block for displaying the first information as estimated information in the display device of the consumer side electronic terminal. Block generating means and display content changing means for changing estimate information (that is, first information) displayed in the display block partitioned in the display device in the consumer-side electronic terminal. Such display block generating means and display content changing means function in the first stage of electronic commerce, and are used specifically in the stage of negotiating the contents of the commercial transaction.

  The display block generation means newly displays the estimate on the display device of the consumer side terminal 30 that has a business talk with the provider terminal when the provider side terminal 40 starts creating the estimate. A window (ie "display block") is displayed. Information (first information) for specifying the contents of the commercial transaction in the estimate is displayed in a form in a window displayed on the display device of the consumer side terminal 30, such as telephone, fax, chat or e-mail. Negotiations are performed between the provider and the consumer through various communication means, and the input result or the change result is instantly (by inputting or changing the result in the provider side terminal 40 ( In real time), it is displayed in a manner reflected in the estimated contents in the window displayed on the display device of the consumer side terminal 30.

  Therefore, the provider side terminal 40 (that is, the “information display device”) includes a means for inputting estimated information, and when the estimated information is input, this is sent to the consumer side terminal 30. It is described to issue a drawing command for displaying in a separate window and to issue a command to reload (reload) the estimate information to the consumer side terminal 30 when the estimate information is changed. The program will be executed.

  As a result, the customer can proceed with the negotiation while confirming the contents of the estimate, and if any changes are made, the changes can be confirmed immediately. Business negotiations can proceed as if negotiating.

  Further, the provider side terminal 40 is preferably configured to hold a transaction object that can be provided by itself and a holding amount (that is, a remaining amount) for each transaction object. The provider-side terminal 40 stores inventory data having items as shown in FIG. 7C and product data having items as shown in FIG. 7D in a table, file, or database format. This can be realized by holding the means. As the inventory data, the product code can be used as a main key, and the remaining amount of the product code (the product with the mark) can be held, and the company code information can be held as necessary. In addition, as the product data, the product code is the primary key, and in addition to the product name, price, product detailed information, etc., information suitable for use in negotiations in actual business transactions, such as minimum price and consumption tax amount, etc. In addition, accompanying information such as a company code can be described.

  The provider side terminal 40 is provided with a transaction number that is attached to transaction information such as an estimate for managing a transaction object and its transaction volume that are currently transactable and confirming a transaction with a consumer. , A program for requesting the central server 10 to receive it, assigning a transaction object for the transaction volume, and transmitting the transaction information with the transaction number to the provider terminal 40 and the commercial transaction management device Is introduced.

  The provider-side terminal B (40B) includes a configuration or a device for managing the remaining amount (inventory amount) on the provider-side terminal 40 side. In the provider-side terminal A, such a remaining amount is provided. It is possible to rely on the central server 10 for managing the remaining amount (stock amount) without providing a configuration or device for managing (stock amount). As described above, when the central server 10 manages the remaining amount (inventory amount) in any of the provider side terminals 40, it is necessary to provide at least the inventory data in the storage unit of the central server 10. In this case, it is desirable that product data describing a product code referred to by the inventory data is also provided in the central server 10. The provider terminal 40 can also hold past purchase histories and the like. In this case, the computer 800 constituting the consumer side terminal 30 can also store the purchase history data as shown in FIG. However, in consideration of risks such as information leakage, it is desirable that the purchase history data be managed by the central server 10 as described above.

  The customer side terminal 30 must be connected to at least a network such as the Internet, and needs to have a program (for example, a program such as a Web browser) that can acquire or view information. Can also be held. In this case, the computer constituting the consumer side terminal 30 can also store the purchase history data as shown in FIG. 7E in the storage means. However, even in this case, it is desirable that the purchase history data is managed by the central server 10 as described above in view of risks such as information leakage.

  The central server 10, the credit server 20, the customer side terminal 30, and the provider side terminal 40 configured as described above cooperate with each other in issuing a quote when transferring a product, checking the quote, and storing the quote. I do. The flow of this process will be described with reference to FIGS.

  FIG. 4 shows a flow of this series of processing. First, the provider side terminal 40 which is a product provider and the consumer side terminal 30 which is a consumer are user IDs and passwords in the central server 10. By verification, authentication that the user is using the system is acquired (not shown). By acquiring this authentication, the consumer can use the customer side terminal 30 to access the provider side terminal 40 operated by each of the plurality of existing providers via the network. Negotiations can be made with 40 for commercial transactions (in this case, transfer of goods). This negotiation may be performed via each terminal such as chat and e-mail, or may be performed without using the terminal such as a telephone or a facsimile. However, even when conducting a business transaction by telephone or voice chat, at least the customer side terminal 30 displays estimate information as transaction information so that the contents can be confirmed visually as well as by voice. It is desirable to keep it. In this way, by displaying on the consumer side terminal 30 images that can be visually confirmed as well as voice, it is possible to eliminate misunderstandings such as mistakes in commercial transactions.

  In the actual negotiation using the commercial transaction management system according to the present embodiment, the consumer and the provider can negotiate the necessary product, the necessary amount of the product, the delivery date, the price, and the like. In this negotiation, the provider can present the delivery date and the quantity that can be delivered by referring to the inventory data held by the provider side terminal 40, and also the information on the lowest price held in the product data for the sales price. It can be identified by reference. Furthermore, the merchandise provider and the consumer can refer to the historical data held by the central server 10 and determine the validity of the current transfer consideration and quantity from the past sales record and purchase record. is there.

  In such negotiations, as described above, the provider side terminal 40 displays the estimated information (first information) on the display device of the consumer side terminal 30 and the estimated information (that is, the first information). By providing a display content change means that immediately displays in the display block reflecting changes in information), etc., it is possible to present an estimate to the consumer side, so that the parties to the transaction can visually specify the details of the negotiation It becomes possible to grasp it. Therefore, the provider side terminal 40 starts processing for creating an estimate as such transaction information in this electronic commerce. At the start of the estimate creation process, the provider side terminal 40 first requests the central server 10 to issue an estimate number and receives it. Such an estimate number can be used as a common index when confirming the transaction contents in the provider side terminal 40, the consumer side terminal 30, and the central server 10. Requests and receipts for issuing an estimate number can be sent and received in the form of an e-mail, or can be made via a Web browser.

  The process for creating, confirming, confirming and saving the estimate will be described with reference to FIGS.

  First, as shown in the data flow diagram of FIG. 3, first, the provider side terminal 40 requests the central server 10 to issue an estimate number prior to the creation of the estimate. In response to this request, the central server 10 issues an estimate number to the provider side terminal 40. The estimate number issued here is a unique value, and this value can be issued by the program processing in the central server 10 without any operator processing. The provider-side terminal 40 creates an estimate (an estimate in electronic data format) with this estimate number in the procedure described later, and further, the estimate signed with the first private key held by the provider-side terminal 40 The document is transmitted to the customer side terminal 30. The customer side terminal 30 decrypts the quotation encrypted with the first secret key with the first public key, and confirms the contents of the quotation. In addition, in the estimate information transmitted to the consumer side terminal 30, the estimate number given by the central server 10 is described as a matter of course. In the consumer side terminal 30, after confirming the contents of the estimate, if it can be approved, the information on the acceptance side is transmitted to the provider side terminal 40. Confirmation of acceptance of the estimate content is not limited to information communication between electronic terminals, but can be performed by telephone or facsimile. If the contents of the quotation cannot be approved, the provider is notified of this, and a request to create and issue a quotation is issued again. For the reissued estimate, the estimate number previously given from the central server 10 may be used, or a new estimate number may be requested separately.

  In the provider side terminal 40, after the consumer's consent is obtained, the central server 10 signs the estimate with the same content as the estimate information previously provided to the provider side terminal 40 with the same first secret key. Send to. On the other hand, in the customer side terminal 30, the quotation sent from the provider side terminal 40 is first decrypted with the first public key, and after confirming the contents, the customer side terminal 30 holds it. The second private key is signed again and transmitted to the central server 10.

  The central server 10 decrypts the estimate in electronic data format transmitted from the provider side terminal 40 with the first public key, and decrypts the estimate sent from the consumer side terminal 30 with the second public key. Then, check the identity of the contents of both quotations. If the identity is confirmed, the central server 10 notifies the provider side terminal 40 that preparation for finalizing the estimate is complete. In this notification, an e-mail or the like holding information indicating that the estimate number and estimate confirmation preparation is completed is transmitted, or a file or index of the estimate sent from the provider side terminal 40 to the central server 10 ( Or the title), an identifier indicating that the preparation for finalizing the estimated content is completed can be displayed.

  The provider side terminal 40 receives information from the central server 10 that preparation for the confirmation of the estimate has been completed, and notifies the customer side terminal 30 accordingly. For this notification, as a matter of course, a method using communication between terminals such as e-mail or chat may be used, or a telephone or facsimile may be used. The consumer side terminal 30 stores the estimate sent from the provider side terminal 40 at the stage of receiving the information on the confirmation of the estimate from the provider.

  In the above processing, the secret key and the public key are encryptions of information transmitted by the first secret key and the first public key, and the second secret key and the second public key, which are uniquely matched to each other. Information that is encrypted and decrypted, the key used for encryption and the key used for decryption are separated, and the key used for encryption cannot be decrypted, and it is easy to determine the other from one This information is configured so that it cannot be performed. It is also possible to use a public key that has been published for encryption and use a secret key for decryption. In this case, the owner of the key can manage only the key used for decryption so that others do not know it, and can disclose the key used for encryption.

  Through the above processing, the estimate issued by the provider side terminal 40 has the signature of the first private key in the provider, so it can be confirmed that the provider has issued it without fail, and the customer can estimate The contents of the certificate can be confirmed, and it can be confirmed by the signature of the second secret key at the consumer that the agreement has been made. And since the estimate document (ie, the estimate content) established between the provider and the consumer is stored not only by the provider and the consumer but also by the central server 10, the credibility of the confirmed transaction content is guaranteed. In addition, it is possible to refer from anywhere by specifying the estimate number.

  Next, referring to the flowcharts of FIGS. 8 and 9 for the flow of processing in the provider side terminal 40 in the process of creating an estimate as described above and finalizing the contents, in particular, the procedure for creating an estimate is shown in FIG. This process will be described with reference to the flowchart of FIG.

  First, prior to initiating negotiations for transfer in a commercial transaction, as described above, user information is collated in the central server 10 via, for example, the Internet, and with a customer who has accessed the provider terminal 40 after login. Negotiate commercial transactions while referring to quotations displayed and changed in real time. The communication between the provider side terminal 40 and the customer side terminal 30 after the login can be performed by a peer-to-peer method, and thus, more reliable real-time exchange can be performed without using the HTTP protocol. It can be carried out. Then, the creation of the estimate in this negotiation can be performed, for example, according to the procedure shown in the flowcharts of FIGS.

  That is, first, in order to conduct a commercial transaction on the consumer side, the provider side terminal 40 published on the Internet is accessed and negotiation of the commercial transaction is started. Specifically, when the provider-side terminal 40 is specified from the customer-side terminal 30 and the start of chat is requested to the provider-side terminal 40, a window for chat communication opens on the provider-side terminal 40. . In this chat, while sending and replying, the chat connection is maintained and the business negotiations are mutually proceeded. When the content of the business negotiations becomes concrete, the consumer side terminal 30 sends to the provider side terminal 40 Request an estimate. The provider-side terminal 40 receives information instructing the request for creating the estimate and starts creating an estimate. When creating this estimate, a unique estimate number is obtained from the central server 10 as described above, and an estimate with this estimate number is created.

  In creating the estimate, the provider terminal 40 selects a form that matches the estimate to be created from the form database provided in the external storage device 810 constituting the estimate, and reads it into the memory 802. Then, estimate information such as a product to be estimated, service, price, delivery date, etc. is input, and the estimate preparation work is completed. The created estimate is stored as an estimate file in the external storage device 810 of the provider terminal 40, and at the same time, by executing an estimate sending command for instructing estimate sending by an operation from the input means, the consumer Another window is generated and displayed in the display device of the side terminal 30. However, when saving the created estimate, as shown in FIG. 8, in addition to saving it in the provider side terminal 40, the created estimate information is transmitted to the central server 10, and the central server 10 is trusted. It can also be used as a storage place for quotations. The estimate stored in the central server 10 can also be referred to as an estimate history from a page such as “My Page” on the portal site provided by the provider or consumer from the central server 10 side.

  In the case of creating an estimate in the provider side terminal 40, for example, an estimate creation screen 41 as shown in FIG. 10 is displayed on the display device 806 of the provider side terminal 40, and the transaction target is indicated by a product code or a product name. The estimate 50 is created by searching for and specifying the product to be obtained and inputting the transfer quantity and unit price. The created estimate 50 is displayed in a separate window as the estimate 50 in the display device 806 of the consumer side terminal 30 as shown in FIG. 11, for example. In this estimate 50, of course, in addition to the name, price, quantity, etc. of the product to be traded, the name of the provider, the status of the estimate being created, the date of issue, the expiration date, etc. Is displayed. In FIGS. 10 and 11, a chat column 51 is provided separately from the estimate creation screen 41 and the estimate 50 for communication between the transaction parties.

  Then, using this estimate, that is, the estimate 50 displayed on the customer side terminal 30 as a starting point, the customer negotiates a transaction using a communication means such as chat, e-mail, telephone, fax, etc. When a request for a quote correction request is received, a quote correction is started.

  A processing flow for correcting the estimate will be described with reference to FIG. First, upon receiving a request for an estimate correction from the consumer side, the consumer side terminal 30 corrects the estimate content from an estimate creation screen 41 as shown in FIG. Then, the contents (that is, the estimate 50) are displayed on the display device 806 of the consumer side terminal 30, and when the consumer's consent is obtained with respect to the estimate contents, the estimate creation work is completed, and the result is calculated by the above-described estimate. Save to file. When saving to the estimate file, in addition to saving the completed estimate information, the history or history of the change can also be saved. As described above, the history of this change can be stored in the storage means of the central server 10, or can be stored in each node (NODE) of the provider side terminal 40 and the consumer terminal. At this time, in order to increase the reliability of the change history, as described above, it is possible to perform the proof by encrypting with the other party's private key.

  And after producing an estimate as mentioned above, operation which transmits the produced estimate to the consumer side terminal 30 is performed, and this is displayed on the display apparatus of the consumer side terminal 30. FIG. In this estimate transmission operation, for example, an estimate transmission command is executed by selecting a button such as “Send current estimate to customer” provided in the estimate creation screen as shown in FIG. Can be configured.

  On the consumer side, in the case of accepting the estimate content displayed on the display device of the electronic terminal, a notification of confirmation of the estimate is transmitted to the provider side terminal 40. In response to this, the provider side terminal 40 performs the above-described processing to finalize the estimate, saves the confirmed estimate, and transmits it to the central server 10. When the central server 10 receives the confirmed estimate, it saves it in the confirmed estimate file, and displays the confirmed estimate with the same contents on the display devices of the provider side terminal 40 and the consumer side terminal 30.

  Furthermore, in this estimate preparation process, the provider side terminal 40 manages the transaction amount (transfer quantity) of the product to be traded in the provider side terminal 40 in order to confirm whether or not it is held as inventory. It is also possible to access the inventory information and determine whether or not the inventory of the product to be traded is sufficient. If the stock quantity is insufficient, the process returns to the quotation creation start stage or the negotiation stage with the customer again. On the other hand, when the inventory quantity is sufficient, an allocation process for allocating the inventory for the transaction quantity in the negotiation to the transaction is performed. If the allocation process is not performed for some reason, the process returns to the estimate creation start stage or the negotiation stage with the customer again in the same manner as in the case of the shortage of inventory. Then, when the inventory allocation process is successful, an estimate is prepared and transmitted to the consumer side terminal 30 by the above procedure. And when a consumer agrees with this estimate content, the estimate content is decided by the process which intervened the said central server 10, and a quote is preserve | saved in the transaction side terminal and the consumer side terminal 30. FIG. On the other hand, if the customer side does not agree to the contents of the estimate, the prepared estimate is discarded and the previously allocated inventory quantity is released.

  By carrying out the processing as described above, since the inventory corresponding to the transaction quantity is allocated prior to the creation of the estimate, it is ensured that the consumer can reliably secure the product to be traded. In addition, the inventory management on the provider side can also allocate the inventory in consideration of not only the currently available inventory quantity that can be provided, but also the arrival quantity of the transaction target products that will arrive in the near future. In this case, details such as the delivery date can be described in an estimate in electronic data format, and can also be confirmed by negotiation between the parties via chat or telephone.

  FIG. 6 shows the flow of the actual ordering process after the estimate is created by such processing, the contents are confirmed and held by the provider side terminal 40, the customer side terminal 30 and the central server 10, respectively. This will be described with reference to a flowchart.

  First, when starting the ordering process, user authentication is first performed via the central server 10. After the user authentication is completed and logged in, the user confirms the contents by browsing the previously established quotation. The estimate number assigned in the central server 10 can be used for calling the estimate. Then, the estimate is browsed, the expiration date of the estimate is confirmed, and if the expiration date has passed, the expiration date is displayed, the estimate is discarded, and the inventory allocated in the provider side terminal 40 is released. To do. It should be noted that the release of the inventory at the provider side terminal 40 can be released without understanding the processing of the operator by the inventory management program at the provider side terminal 40 when the expiration date of the estimate expires.

  In the confirmation of the estimate, when the estimate is within the expiration date and the ordering process is performed, the purchase button provided in the estimate displayed on the display is pressed in the process at the consumer side terminal 30 To do. However, the start of the ordering process is not limited to such a user interface, and information indicating the intention of placing an order may be transmitted to the provider side terminal 40 directly or via the central server 10. Can be implemented without problems.

  By the purchase intention display in the consumer, the provider side terminal 40 or the central server 10 requests the customer side terminal 30 to input the information on the destination of the commodity to be traded and the information for settlement. To do. The provider side terminal 40 or the central server 10 checks the appropriateness of the input information, and if it is incomplete, requests input again. On the other hand, if the input destination information and settlement information are appropriate, credit processing for settlement is performed next. In this credit process, all or any of the payment information transmitted from the customer side terminal 30 is actually transmitted to the external credit server 20 that provides the credit check service, and the judgment result is received. Can be done. If the credit judgment result transmitted from the external credit server 20 indicates that no credit is granted, the settlement impossible information indicating that payment cannot be made is displayed in text and the payment is made to the customer side terminal 30. Request re-input of information. On the other hand, when credit is given in the determination result transmitted from the external credit server 20, the ordering process is completed, and inventory management is performed by reducing the stock allocated at the stage of creating the estimate.

  Then, at the stage where the ordering process and the settlement process are completed by the above process, the provider side terminal 40 outputs information instructing the shipment of the product, performs the sales process for the settled consideration, and completes a series of commercial transactions. .
