As shown in the figure, a list of coupon data held by the user is displayed on the screen, and the user selects one or more candidates to be used from the coupon data displayed on the screen, and selects “ "" Is displayed on the input unit 106 such as a mouse. The screen image shown in FIG. 8 is a screen for selecting coupon data to be used.

  FIG. 9 is a modification of the screen image shown in FIG. The screen image shown in FIG. 9 is a screen image that is displayed before the coupon data selection process is performed by the EC server 102, similarly to the screen image shown in FIG. 8. As shown in the figure, a list of coupon data held by the user is displayed on the screen, and the user selects coupon data on the EC server 102 side that does not use the coupon for the current product among the coupons displayed on the screen. Coupon data to be excluded from processing is selected, and the “re” displayed in the check box is canceled by the input unit 106 such as a mouse and is not displayed.

  In the screen image shown in FIG. 8, “Re” is not displayed in the check box by default, whereas in the screen image shown in FIG. 9, all “Re” is displayed in the check box by default. It is different.

  Next, the screen image shown in FIG. 10 is a modification of the order confirmation screen described in FIG. As shown in the drawing, when a user orders one or more products sold on the Web (when they are put in a shopping cart), an order confirmation screen is displayed as a temporary order. As shown in the figure, two types of products, “product B” and “product C”, can be provisionally ordered at one time. Accordingly, the EC server 102 can receive an order for the “product B” and “product C” in a lump.

  The screen image shown in FIG. 11 is, for example, a list of coupon data held by the user displayed on the screen when the “next” button is clicked with a mouse or the like on the order confirmation screen shown in FIG. As shown in the figure, “Re” is displayed in all check boxes on the default screen. That is, all coupon data is the target of coupon selection processing. When there is coupon data to be excluded from the coupon selection process, the user selects the coupon data, and, for example, “discount rate coupon 005” or the like, the check box “Le” displayed on the left side of the coupon name The input unit 106 cancels the display and hides it.

  The coupon data displayed in the coupon list shown in FIG. 8, FIG. 9, and FIG. 11 includes a discount rate coupon that can be purchased at a predetermined rate such as 20%, and a discount rate coupon of 3000 yen, etc. A discount coupon that can be purchased by subtracting a predetermined amount from the purchase price of the product, a shipping coupon that can deliver the product free of charge, and the like are included.

  In addition, the above coupon data includes product coupons that can be applied only to specific products, category coupons that can be applied to all products that belong to that category, such as personal computers with multiple models, or specific sales. Store coupons that can be applied to all products sold in the store (mall) are included.

  By combining the discount rate coupon or the product coupon, the store side can provide various benefits to the user. For example, by combining a discount rate coupon (discount rate 20%) and a category coupon (category “home appliance”), all home appliances sold on the Web are discounted by 20% from the price of the product, and the user purchases can do. The coupon data has a simultaneous use flag, and the simultaneous use flag is set to “ON”, so that the coupon data can be used simultaneously.

  Therefore, the store that provides the product determines the content of the privilege to be given to the user according to the sales status of the product, future sales strategy, etc., and distributes coupon data according to the content to the user. It is possible to expand sales at retail stores and promote sales of products.

  The screen images shown in FIGS. 6 to 11 have been described by way of example of cases where a screen image for selecting a payment method using a credit card or the like is not included, but the present invention is not limited to such an example. When a screen image for selecting is separately displayed, a coupon selection screen may further include a screen for selecting a settlement method.

  Next, the data structure of the database according to the present embodiment will be described with reference to FIGS.

  As shown in FIG. 12, the product coupon master database 420 and the product coupon detail database 414 have a 1-to-n relationship, and the product coupon master database 420 and the coupon association information database 418 also have a 1-to-n relationship. The database 414 and the product coupon usage detail database 423 also have a one-to-n relationship. Each of the databases is stored in the storage device 414 of the DB server 102c.

  The product coupon detail database 414 stores coupon data. The stored coupon data is associated with user information in the user information database 416. That is, based on the user information of the user, the coupon data held by the user can be read and acquired from the product coupon detail database 414.

  Further, as shown in FIG. 12, the coupon data stored in the product coupon detail database 414 indicates, for example, a discount rate for discounting the purchase price of the product and a coupon that can be used in combination with other coupons. And at least a simultaneous use flag. Note that the present invention is not limited to this example, and for example, the coupon data may further include a discount amount that discounts a certain amount from the purchase price of the product.

  Next, items that can be the primary key of each database shown in FIG. 12 will be described with reference to FIG. FIG. 13 is an explanatory diagram showing an outline of data items in the database according to the present embodiment.

  As shown in FIG. 13, “coupon type” identifies the type of issued coupon. For example, when 1 is set in the coupon type item, the coupon is discounted by a certain amount. Indicates that it is a coupon. “Issuance year” identifies the year in which the coupon was issued, and “issuer number” is a number for managing the coupon. For example, the coupon number is set to a three-digit number for each coupon type. The coupon number is a number assigned to a coupon data unit stored in the product coupon detail DB 421 that can be used by the user.

  Next, merchandise purchase processing in the electronic commerce system 100 will be described with reference to FIGS. It should be noted that a coupon selection process, which is a characteristic process according to the present embodiment, is executed in the product purchase process.

  As shown in FIG. 14, first, a desired product is clicked with a mouse or the like from among products displayed on the screen of the user terminal 101, and one or more products are put into a so-called shopping basket (S1401). ). At this point, the EC server 102 has not yet officially received a product order, but is still in a provisional order stage.

  Next, when all the products are selected and the temporary order is completed, the user terminal 101 displays a login screen on the display unit 108 and accepts input of authentication information such as a user ID and a password from the user. If the input of authentication information is received, an authentication process will be performed based on the said authentication information by the application server 102, and login will be performed (S1403).

  After the login is completed (S1403), the order contents of all the products that have been provisionally ordered (S1401) are displayed on the screen of the user terminal 101 (S1405). As described above, when the user confirms the contents and clicks the “next” button displayed on the screen with the mouse or the like, the user terminal 101 displays the product order data of all the products for which orders are received from the user. It is generated in a lump and transmitted to the Web server 102a.

  The Web server 102a transfers the received product order data to the application server 102b. When the collective order receiving unit 318 of the application server 102b acquires the product order data, the collective order receiving unit 318 orders one or more products at a time. Note that the collective order receiving unit 318 is not limited to a case where a plurality of products are included in one product order data, for example, even when a plurality of product order data is transmitted for each product, Two or more products can be ordered. Data such as the product number of the ordered product and the order number is stored in the storage device 314 or the memory 304.

  Next, the coupon extraction unit 320 acquires the coupon data owned by the user who is the order source of the product ordered by the collective order receiving unit 318 from the product coupon detail DB 421 (S1407).

  Next, the Web server 102 a transmits Web page data describing the order contents to the user terminal 101 via the network 103 in order to prompt the user to confirm again. On the screen of the user terminal 101, a Web page (order confirmation screen) in which the details of the order are specified is displayed (S1409).

  Further, when the product is a tangible object or the like, when the user terminal 101 receives information such as a requester for delivering the product and a delivery destination via the input unit 106 (S1411), the information such as the delivery destination is obtained from the application server. 102b.

  Next, on the screen of the user terminal 101, a list of user coupon data stored in the product coupon detail DB 421 is displayed (S1413). As described above, the check box is displayed on the coupon data list screen. For example, if “re” is displayed in all of the check boxes by default, or all “re” is displayed. It is either not the case, but it is not limited to such an example.

  Moreover, although the case where the coupon data list screen is displayed has been described as an example in the purchase processing flowchart according to the present embodiment (S1413), the present invention is not limited to this example. For example, the coupon data list screen is displayed. May not be displayed. In the above case, for example, after execution of S1413, a list of coupon data automatically selected by the coupon selection unit 321 is displayed on the screen of the user terminal 101. If you do not want to use the coupon data, for example, you can hide the check box “re” displayed on the coupon data list screen and let the coupon selection unit 321 select another coupon data again. it can.

  Further, the case where a list of coupon data is displayed (S1413) has been described as an example, but the user terminal 101 displays a payment method selection screen for selecting a payment method such as a credit card or a debit card together with the list of coupon data. It may be displayed on the display screen.

  Next, the coupon extraction unit 320 of the application server 102b extracts information such as the product name and product identification number of the product ordered by the collective order receiving unit 318 (S1415).

  By receiving the product order data from the user terminal 101, the collective order receiving unit 318, for example, as shown in FIG. 15, “product A”, “product B”, “product C” belonging to category 1 or category 2 is displayed. , And “product D” can be received in a lump. Note that the category is an attribute of a product, and examples thereof include home appliances, sports equipment, or game software.

  Next, the coupon extraction unit 320 extracts coupon data owned by the user who ordered the product from the product coupon detail DB 421 based on the user information stored in the user information DB 416.

  Furthermore, the coupon extraction part 320 extracts the coupon data applicable to goods out of the coupon data which a user owns based on the coupon link information etc. which were stored in coupon link information DB418 (S1417). For each ordered product, coupon data suitable for the product is extracted.

  Next, the coupon selection unit 321 selects the coupon data with the highest discount rate from the coupon data extracted by the extraction process (S1417) of the coupon extraction unit 320 (S1419). This is because if the discount rate is the highest, the purchase price of the user can be suppressed at the lowest price, and the user is likely to use it.

  In addition, although the coupon selection part 321 concerning this Embodiment selected as an example the case where the thing with the highest discount rate is selected among extracted coupon data (S1419), it is not limited to this example, For example, the coupon selection unit 321 can be implemented even when selecting the one with the highest discount amount among a plurality of coupon data.

  Further, coupon data having a discount rate as a privilege can be used at the same discount rate for all products to which the coupon data can be applied among products ordered by a single order processing by the batch order receiving unit 318.

  For example, when there are two products “product A” and “product B” that can use coupon data, “product A” and “product B”, not “product A” and “product B”, The coupon data can be used for both “product B”.

  Next, as shown in FIG. 16, the coupon selection unit 321 determines whether or not the coupon data selected in S1419 is one type / one (S1421). Of the coupon data selected in S1419, the coupon selection unit 321 further selects only coupon data adapted to the category of the product (S1423).

  That is, when there are a plurality of coupon data with the same discount rate, the coupon data that is selected with priority next is coupon data adapted to the product category.

  In addition, although the coupon selection part 321 concerning this Embodiment gave and demonstrated as an example the case where only the coupon data applicable to a category was further selected (S1423), it is not limited to this example, For example, the coupon selection part 321 May be a case where only coupon data applicable to a store is selected based on the store number or the like.

  The coupon selection unit 321 again determines whether or not the coupon data selected in S1423 is one type / one (S1425). If there are still multiple types / multiple coupons, the coupon selection unit 321 determines the coupon data selected in S1423. Among them, the coupon selection unit 321 further selects only the coupon data with the closest expiration date (S1427).

  Similarly to the above, when there are a plurality of coupon data having the same discount rate and adapting to the product category, the coupon data with the latest expiration date is preferentially selected from the coupon data.

  As a result of selection by the coupon selection unit 321, if there are still a plurality of types or a plurality of candidate coupon data (S 1429), the coupon selection unit 321 has one oldest stored order in the product coupon specification DB 421. Select (S1431).

  The selection process (S1415 to S1431) of coupon data that is a candidate for using a coupon for a product is thus completed. The coupon data selection process (S1415 to S1431) is executed in the same manner as described above for each ordered product.

  When the simultaneous use flag is set in the selected coupon data, a coupon data selection process (S1415 to S1431) is executed in order to select another coupon data.

  Therefore, when the simultaneous use flag is set in the coupon data, the coupon selection unit 321 can automatically select at least two pieces of coupon data from the user's coupon data.

  Here, the coupon data selection process will be specifically described with reference to FIGS. 15 and 17.

  As shown in FIG. 15, when the EC server 102 receives an order for the products “product A” to “product D” and the user of the orderer has coupon data as shown in FIG. The coupon extraction unit 321 first extracts coupon data applicable to “product A” (S1417). The extracted coupon data is a product A discount coupon 1, a product A discount coupon 2, a category 1 discount coupon, a discount coupon a, and a discount coupon b.

  The product A discount coupon is coupon data applicable only to “product A”, the category 1 discount coupon is coupon data applicable only to products belonging to “category 1”, and the discount coupon is Although it is coupon data applicable to all goods, it is not limited to this example.

  Next, the coupon selection unit 321 selects coupon data having the highest discount rate from the coupon data extracted in S1417 (S1419). As shown in FIG. 17, the coupon data to be selected is a product A discount coupon 1.

  Further, since the product A discount coupon 1 has the simultaneous use flag set to “ON”, the coupon selection unit 321 selects one more coupon data. First, coupon data with the highest discount rate is selected from the coupon data extracted in S1417 excluding the product A discount coupon 1 (S1419). The selected coupon data is a category 1 discount coupon and a discount coupon b.

  Since there are a plurality of the selected coupon data, the coupon selection unit 321 preferentially selects coupon data suitable for the product category (S1423). Since the selected coupon data is only the category 1 discount coupon, the selection processing of another coupon data is also terminated here. This completes the process of selecting coupon data related to “product A”.

  If the simultaneous use flag is set in the coupon data, the coupon selection unit 321 has the highest discount rate among the coupon data applicable to the product, as in the coupon data selection process related to the “product A”. A combination of high coupon data can be selected.

  Note that the coupon selection unit 321 according to the present embodiment can select a combination of two coupon data when the simultaneous use flag is set in the coupon data, but is not limited to this example. The coupon selection unit 321 can be implemented even when a combination of three or more coupon data is selected.

  Similarly, the coupon data selection process is executed for “product B”, and the category 1 discount coupon is preferentially selected. Since the coupon data can be applied to all products in one order, the category 1 discount coupon can be applied to both “product A” and “product B”. The discount rate does not change even if you purchase multiple items of the same product, but it is not limited to this example.

  Coupon data selection processing is also executed for “product C” and “product D”, and discount coupon b is preferentially selected.

  Processing for selecting and selecting whether or not the coupon data is appropriate for the product in order to automatically select coupon data that can be used for the product on the EC server 102 side by the coupon data selection processing. The convenience of using coupon data by the user can be improved. Furthermore, since coupon data that is not to be used can be designated in advance, the selection process for selecting coupon data can be made quicker and more efficient, and the convenience of using the coupon data can be further improved.

  On the other hand, the store side can reduce the complexity of managing coupon data by the coupon data selection process, so that various coupon data can be distributed according to the results of marketing research, for example. Furthermore, the utilization rate of the coupon data is improved, which can greatly contribute to the sales promotion of products.

  Conventionally, since the coupon type is one type of discount coupon, the form of using coupon data is simple and not attractive to the user. In addition, since the types of coupons exist only for specific products for dealers, coupon data that can be applied to all products is distributed for the purpose of intensive sales enhancement for all products belonging to the same category. , I could not adopt a flexible sales strategy.

  Returning to FIG. 16 again, after selecting the coupon data, if the simultaneous use flag is set in the selected coupon data, the discount rate of the coupon data and the discount rate of the other selected coupon data are also selected. Are added together (S1433).

  Next, based on the discount rate of the selected coupon data, a discount amount is calculated from the purchase price of the product (S1435).

  For example, as shown in FIG. 15 and FIG. 17, the discount amount of “product A” is 50% when the coupon data (product A discount coupon 1, category 1 discount coupon) selected for “product A” is 50%. (30% + 20%) and the purchase price of “product A” is 10498 yen, so the discount amount is 5249 yen. In the calculation of the discount amount, rounding up is performed, but the present invention is not limited to this example.

  It should be noted that the processing from the product extraction process (S1415) to the discount amount calculation process (S1435) is repeatedly executed until completion for each ordered product (S1437). When the discount amount calculation processing (S1435) is completed for all products (S1437), the discount amounts for each product are added together (S1439), and the total discount amount is subtracted from the total purchase price of all products. , The payment amount is calculated (S1441).

  Here, with reference to FIG. 17 and FIG. 18, the processing from the discount amount summation processing (S 1439) to the payment amount calculation processing (S 1441) will be described in detail. Based on the discount rate from “product A” to “product D” and the purchase price (product unit price) of each product, the discount amount of each product is 5249 yen for “product A”, 8400 yen for “product B”, “product” “C” is 6300 yen, and “Product D” is 1050 yen.

  Therefore, the total discount amount obtained by adding the discount amounts of the above-mentioned products is 20999 yen (5249 yen + 8400 yen + 6300 yen + 1050 yen). Furthermore, the total payment amount obtained by subtracting the total discount amount from the total sum of the purchase price of each product is 69249 yen. The amount paid by the user at the time of settlement is the total amount paid.

  Next, Web page data describing details such as the total payment amount is transmitted from the Web server 102a to the user terminal 101, and a confirmation screen for confirming the order is displayed on the screen of the user terminal 101 (S1443). ).

  Further, when the user operates the input unit 106 and the “confirm” button displayed on the screen is pressed, the user terminal 101 transmits order confirmation data to the EC server 102, and the order confirmation processing is performed. It is executed (S1445). In the order confirmation process, for example, the confirmation unit 325 sets a used flag in the used coupon data stored in the product coupon detail DB 421, and further stores the coupon data in the product coupon use detail DB 423.

  When the order confirmation process (S1445) is finished, finally, a message indicating that the product purchase process is completed is displayed on the screen of the user terminal 101 (S1447), and the series of product purchase processes is finished.

  In the series of purchase processing according to the present embodiment, the case of only the discount rate coupon has been described as an example. However, the present invention is not limited to this example. For example, the discount rate coupon and the discount coupon discounted by a certain amount are available. It can be implemented even when such coupons are mixed.

  Next, the series of merchandise purchase processing described above can be executed by dedicated hardware or can be executed by software. When a series of product purchase processing is performed by software, a program constituting the software needs to be installed in the user terminal 101 and the EC server 102 in advance.

  The program is recorded in advance in a storage device or memory corresponding to a hard disk or the like as a recording medium built in the computer of the user terminal 101 or the EC server 102.

  The program is installed on the user terminal 101 or the EC server 102 as described above, and is also transferred wirelessly from the download site to the user terminal 101 or the EC server 102 via a digital satellite broadcasting artificial satellite. Or via a network such as a LAN (Local Area Network) or the Internet, the user terminal 101 or the EC server 102 can store the built-in storage device or the like on the basis of the transferred program. Can be installed.

  Here, in this specification, the processing steps for describing a program for causing the user terminal 101 or the EC server 102 to perform various processes are not necessarily in the order described in the flowcharts shown in FIGS. Thus, it is not necessary to perform processing in time series, and includes processing executed in parallel or individually (for example, parallel processing or object processing).

  As mentioned above, although preferred embodiment of this invention was described referring an accompanying drawing, this invention is not limited to this example. It is obvious for a person skilled in the art that various changes or modifications can be envisaged within the scope of the technical idea described in the claims, and these are naturally within the technical scope of the present invention.
