Then, the application transmits the identification information of the user terminal 10 such as the telephone number, the service station selected by the user, and the credit card number to the main server 20. When the main server 20 acquires these information, it assigns a user ID (user identification information) that can be distinguished from other users to this user, associates it with the user ID, and uses the identification information of the user terminal 10 and the user. The service station and the credit card number are registered in the user database 31. Further, the main server 20 transmits these information to the user terminal 10.

図２は、燃料油の販売方法のフローチャートである。
図２に示すように、まずユーザは特定のサービスステーションへの来店時に、アプリを操作して該サービスステーションにて割引を受けるためのコード情報を表示させる。ユーザが該操作をするとアプリは、コード生成要求とともにユーザＩＤをメインサーバ２０に送信する（ステップＳ０１）。 FIG. 2 is a flowchart of a fuel oil sales method.
As shown in FIG. 2, when a user first visits a specific service station, he / she operates an application to display code information for receiving a discount at the service station. When the user performs the operation, the application sends the user ID to the main server 20 together with the code generation request (step S01).

メインサーバ２０のユーザ情報取得部２１は、コード生成要求とともにユーザＩＤを取得したら（ステップＳ０２）、値引きデータベース３２を参照して、該ユーザＩＤの値引き情報を特定する（ステップＳ０３）。 When the user information acquisition unit 21 of the main server 20 acquires the user ID together with the code generation request (step S02), the user information acquisition unit 21 refers to the discount database 32 and specifies the discount information of the user ID (step S03).

図３は、ユーザデータベース３１の一例である。図３に示したように、ユーザデータベース３１の値引き特定部２２は、ユーザＩＤに関連付けて、利用サービスステーション、クレジットカード番号、値引き額、最新来店日、年間あるいは月間などの累積購入額、ユーザ端末１０の識別情報を記録している。なお本例では、値引きデータベース３２とユーザデータベース３１とが統合されており、ユーザデータベース３１にユーザＩＤに関連付けてそのユーザの値引き額が記録されている。 FIG. 3 is an example of the user database 31. As shown in FIG. 3, the discount specifying unit 22 of the user database 31 associates with the user ID, the service station used, the credit card number, the discount amount, the latest visit date, the cumulative purchase amount such as annual or monthly, and the user terminal. 10 identification information is recorded. In this example, the discount database 32 and the user database 31 are integrated, and the discount amount of the user is recorded in the user database 31 in association with the user ID.

ここでは、メインサーバ２０はユーザＩＤ：ＡＡＡＡ０からコード生成要求を受けたものとする。メインサーバ２０は、ユーザデータベース３１の中からユーザＩＤ：ＡＡＡＡ０に一致するユーザＩＤを探し、その値引き額５円とクレジットカード番号：１２３４５６７８９を特定する。 Here, it is assumed that the main server 20 receives a code generation request from the user ID: AAAA0. The main server 20 searches the user database 31 for a user ID that matches the user ID: AAAA0, and specifies the discount amount of 5 yen and the credit card number: 123456789.

メインサーバ２０のコード生成部２３は次に、特定した値引き情報とユーザＩＤとクレジットカード情報を一体的に含んでコード化された画像情報としてＱＲコード（登録商標）やバーコードなどのコード情報を生成する（ステップＳ０４）。なお、コード生成部２３は自身でコード情報を生成してもよいし、他のサーバへコード情報の生成を指示し生成されたコード情報を受領するように構成されていてもよい。メインサーバ２０は生成したコード情報をユーザ端末１０へ送信する（ステップＳ０５）。ユーザ端末１０は生成されたコード情報を受信する（ステップＳ０６）と、これをユーザ端末１０内に保存しておく。 Next, the code generation unit 23 of the main server 20 inputs code information such as a QR code (registered trademark) and a barcode as image information encoded by integrally including the specified discount information, user ID and credit card information. Generate (step S04). The code generation unit 23 may generate the code information by itself, or may be configured to instruct another server to generate the code information and receive the generated code information. The main server 20 transmits the generated code information to the user terminal 10 (step S05). When the user terminal 10 receives the generated code information (step S06), it stores it in the user terminal 10.

ユーザは燃料油の供給を受けるためにサービスステーションに来店する。この際、ユーザはまずアプリを操作してユーザ端末１０の表示部１１に保存しておいたコード情報を表示させ、ＰＯＳ端末４０に読み取らせる（ステップＳ０７）。ＰＯＳ端末４０のコード取得部４１は、ユーザ端末１０からコード情報を読み取る（ステップＳ０８）。つまり、ＰＯＳ端末４０はコード情報を介して、ユーザ端末１０から、ユーザＩＤ、クレジットカード情報および値引き情報を取得する。 The user comes to the service station to receive the fuel oil supply. At this time, the user first operates the application to display the code information stored in the display unit 11 of the user terminal 10 and have the POS terminal 40 read it (step S07). The code acquisition unit 41 of the POS terminal 40 reads the code information from the user terminal 10 (step S08). That is, the POS terminal 40 acquires the user ID, the credit card information, and the discount information from the user terminal 10 via the code information.

ユーザはコード情報を提示した後に、計量器５０を操作して燃料油を車両へ供給する。燃料油の供給が終了した後、計量器５０はユーザへ提供した燃料油の油種と数量を特定する（ステップＳ０９）。さらにＰＯＳ端末４０の販売単価特定部４２は、特定した燃料油の油種に応じた標準単価と、コード情報から取得した値引き情報とに基づきユーザに対する販売単価を特定する（ステップＳ１０）。なお、標準単価はサービスステーションの販売員によってＰＯＳ端末４０にあらかじめ記録されている。さらにＰＯＳ端末４０の販売価格特定部４３は、特定した燃料油の油種、数量および販売単価に基づき燃料油の販売価格を算出する（ステップＳ１１）。 After presenting the code information, the user operates the measuring instrument 50 to supply fuel oil to the vehicle. After the supply of fuel oil is completed, the measuring instrument 50 specifies the oil type and quantity of the fuel oil provided to the user (step S09). Further, the sales unit price specifying unit 42 of the POS terminal 40 specifies the sales unit price to the user based on the standard unit price according to the oil type of the specified fuel oil and the discount information acquired from the code information (step S10). The standard unit price is recorded in advance on the POS terminal 40 by the salesperson of the service station. Further, the selling price specifying unit 43 of the POS terminal 40 calculates the selling price of the fuel oil based on the oil type, quantity and selling unit price of the specified fuel oil (step S11).

ＰＯＳ端末４０の決済実行部４４は、算出した販売価格とコード情報から取得したクレジットカード情報を用いて決済を行う（ステップＳ１２）。つまり、決済実行部４４は、クレジットカード情報と販売価格とを含む請求データを決済サーバへ送信する。クレジットカードの信販会社は、このような請求データを受け取ると、月に一度、その月の請求額を合計し、クレジットカードに登録されたユーザの口座から合計の請求額を差し引く。 The payment execution unit 44 of the POS terminal 40 makes a payment using the calculated selling price and the credit card information acquired from the code information (step S12). That is, the payment execution unit 44 transmits the billing data including the credit card information and the selling price to the payment server. When a credit card credit company receives such billing data, it sums up the billing amount for the month once a month and deducts the total billing amount from the user's account registered on the credit card.

さらにＰＯＳ端末４０は、販売価格と販売日時と、コード情報から取得したユーザＩＤをメインサーバ２０に送信する（ステップＳ１３）。メインサーバ２０のデータ蓄積部２４はＰＯＳ端末４０から取得した販売価格、販売日時をユーザＩＤに紐づけてユーザデータベース３１に記録する（ステップＳ１４）。なおＰＯＳ端末４０は販売価格や販売日時の他に、ユーザＩＤとともに油種や数量といったデータをメインサーバ２０に送信し、メインサーバ２０は油種や数量もユーザＩＤに紐づけてユーザデータベース３１に登録するように構成してもよい。 Further, the POS terminal 40 transmits the selling price, the selling date and time, and the user ID acquired from the code information to the main server 20 (step S13). The data storage unit 24 of the main server 20 records the selling price and the selling date and time acquired from the POS terminal 40 in the user database 31 in association with the user ID (step S14). The POS terminal 40 transmits data such as oil type and quantity together with the user ID in addition to the selling price and sales date and time to the main server 20, and the main server 20 links the oil type and quantity to the user ID to the user database 31. It may be configured to register.

なおメインサーバ２０は、ユーザＩＤに紐づいた販売価格と販売日時といったユーザの購入履歴を、ＰＯＳ端末４０から直接取得してもよい。あるいは、ＰＯＳ端末４０がＳＳ端末に購入履歴を送信し、ＳＳ端末がまとめたデータがメインサーバ２０に送信されてもよい。あるいは、ＰＯＳ端末４０が購入履歴をクレジットカードの信販会社のサーバに送信し、クレジットカードの信販会社のサーバがまとめたデータがメインサーバ２０に送信されてもよい。このようにメインサーバ２０のデータ蓄積部２４は、ＰＯＳ端末４０から直接的または間接的にユーザＩＤと販売価格と販売日時とを取得し、ユーザＩＤに販売価格と販売日時とを紐づけてユーザデータベース３１に記録させてもよい。 The main server 20 may directly acquire the user's purchase history such as the selling price and the selling date and time associated with the user ID from the POS terminal 40. Alternatively, the POS terminal 40 may transmit the purchase history to the SS terminal, and the data collected by the SS terminal may be transmitted to the main server 20. Alternatively, the POS terminal 40 may transmit the purchase history to the server of the credit card credit card company, and the data collected by the server of the credit card credit card company may be transmitted to the main server 20. In this way, the data storage unit 24 of the main server 20 directly or indirectly acquires the user ID, the selling price, and the sales date and time from the POS terminal 40, and associates the user ID with the selling price and the sales date and time. It may be recorded in the database 31.

このように本実施形態に係る燃料油の販売方法によれば、コード情報をユーザ端末１０に取得させ、これをＰＯＳ端末４０に読み込ませるだけで、ユーザに応じた値引き額にてクレジットカードによる決済を行うことができ、ユーザの利便性が高められている。また、ユーザはＰＯＳ端末４０に会員カードを読み込ませ、値引きカードを読み込ませ、さらにクレジットカードを読み込ませるといった必要がない。また、ユーザが会員カードやクレジットカードあるいは値引きカードのいずれか一つを忘れて来店したとしても、値引きを受けることができる。つまり、燃料油の値引きを受けるにあたってのユーザの負担が大幅に軽減されている。また、燃料油販売会社にとっても、このようにユーザの負担を軽減しながらユーザの購入情報を取得でき、有益である。
また、ＰＯＳ端末４０がユーザ端末１０から値引き情報を取得するので、ＰＯＳ端末４０がネットワーク上の値引きデータベース３２・ユーザデータベース３１に記録されている値引き情報を参照する必要がなく、決済時の処理速度が高い。 As described above, according to the fuel oil sales method according to the present embodiment, only by having the user terminal 10 acquire the code information and reading the code information into the POS terminal 40, payment by a credit card is made at a discount amount according to the user. Is possible, and the convenience of the user is enhanced. Further, the user does not need to have the POS terminal 40 read the membership card, read the discount card, and further read the credit card. In addition, even if the user forgets one of the membership card, the credit card, and the discount card and comes to the store, the discount can be received. In other words, the burden on the user when receiving a discount on fuel oil is greatly reduced. Further, it is also beneficial for the fuel oil sales company to be able to acquire the purchase information of the user while reducing the burden on the user in this way.
Further, since the POS terminal 40 acquires the discount information from the user terminal 10, it is not necessary for the POS terminal 40 to refer to the discount information recorded in the discount database 32 / user database 31 on the network, and the processing speed at the time of payment is settled. Is high.

なお、このようにして蓄積したユーザの購入履歴に基づき、メインサーバ２０は定期的にユーザの値引き情報を更新するように構成されていてもよい。次にこのような値引き額の決定方法を説明する。
図１に示したように、メインサーバ２０は、学習モデル記録部３４を有している。この学習モデル記録部３４には、購入履歴を入力すると、ユーザに適した値引き額を出力する学習モデルが記録されている。学習モデルとは、機械学習により得られたプログラムである。また、記録部３０には、購入履歴データベース３５が記録されている。この購入履歴データベース３５には、少なくとも所定期間に亘る燃料油の累積購入量と、所定期間における一つ以上の来店日時と、をユーザＩＤに紐づけて記録されている。なお、購入履歴データベース３５はユーザデータベース３１の一部である。 The main server 20 may be configured to periodically update the user's discount information based on the user's purchase history accumulated in this way. Next, a method of determining such a discount amount will be described.
As shown in FIG. 1, the main server 20 has a learning model recording unit 34. The learning model recording unit 34 records a learning model that outputs a discount amount suitable for the user when the purchase history is input. A learning model is a program obtained by machine learning. Further, the purchase history database 35 is recorded in the recording unit 30. In the purchase history database 35, the cumulative purchase amount of fuel oil over at least a predetermined period and the date and time of one or more visits to the store in the predetermined period are recorded in association with the user ID. The purchase history database 35 is a part of the user database 31.

この学習モデルは、例えば、油種、数量、累積購入額、来店頻度、前回来店時からの経過日数、来店時間、エンジンオイルや洗車などの他のサービスや商品の購入頻度・購入数量などと、過去に実施した値引き額とその値引きした結果の来店状況などを教師データとして入力することにより、得ることができる。 This learning model includes, for example, oil type, quantity, cumulative purchase amount, store visit frequency, number of days elapsed since the last visit, store visit time, purchase frequency / purchase quantity of other services and products such as engine oil and car wash, etc. It can be obtained by inputting the discount amount implemented in the past and the store visit status as a result of the discount as teacher data.

例えば、ステップＳ１４にてあるユーザＩＤについて新たな購入履歴が追加されて購入履歴が更新される都度、メインサーバ２０がこのユーザＩＤについて更新された購入履歴を学習モデルに入力し、学習モデルから出力される値引き額を値引き情報としてこのユーザＩＤのユーザデータベース３１または値引きデータベース３２に登録するように構成してもよい。あるいは、月に一度、または数カ月に一度、あるいは一年に一度、ユーザデータベース３１に蓄積された購入履歴に基づき値引き額を特定し、ユーザデータベース３１または値引きデータベース３２に登録するように構成してもよい。 For example, each time a new purchase history is added to the user ID in step S14 and the purchase history is updated, the main server 20 inputs the updated purchase history for this user ID into the learning model and outputs it from the learning model. The discount amount to be given may be configured to be registered in the user database 31 or the discount database 32 of this user ID as discount information. Alternatively, once a month, once every few months, or once a year, the discount amount may be specified based on the purchase history accumulated in the user database 31 and registered in the user database 31 or the discount database 32. good.

なお、サービスステーションは燃料元売り会社に燃料販売業務を委託された業者が運営することがある。この場合、次に説明するように、燃料元売り会社が設定する値引き情報について、サービスステーションの運営業者の承認を得るような構成としてもよい。 The service station may be operated by a company outsourced to a fuel sales company. In this case, as described below, the discount information set by the fuel source sales company may be configured to obtain the approval of the service station operator.

図４は、値引き額決定方法のフローチャートである。図４に示すように、まずメインサーバ２０の仮値引き特定部２５（図１参照）は、ユーザデータベース３１の購入履歴に基づきユーザに応じた仮値引き情報を特定する（ステップＳ２１）。さらに仮値引き特定部２５は、仮値引き情報をユーザＩＤに紐づけて記録した仮値引きデータベース３３に記録する（ステップＳ２２）。 FIG. 4 is a flowchart of the discount amount determination method. As shown in FIG. 4, first, the provisional discount specifying unit 25 (see FIG. 1) of the main server 20 specifies provisional discount information according to the user based on the purchase history of the user database 31 (step S21). Further, the provisional discount specifying unit 25 records the provisional discount information in the provisional discount database 33 recorded in association with the user ID (step S22).

さらにメインサーバ２０の最大値引き特定部２６（図１参照）は、サービスステーションのＳＳ端末５１（図１参照）から、サービスステーションが許容する値引き額である最大値引き情報を取得する（ステップＳ２３）。
さらにメインサーバ２０は、あるサービスステーションに関するユーザＩＤに紐づけられた仮値引き情報を、そのサービスステーションのＳＳ端末５１から取得した最大値引き情報と比較する（ステップＳ２４）。
仮値引き情報が最大値引き情報を上回る値引き額の場合は、メインサーバ２０は最大値引き情報をユーザＩＤに紐づけて値引きデータベース３２（本例ではユーザデータベース３１）に記録する（ステップＳ２５）。仮値引き情報が最大値引き情報を下回る値引き額の場合は、メインサーバ２０は仮値引き情報をユーザＩＤに紐づけて値引きデータベース３２に記録する（ステップＳ２６）。 Further, the maximum discount specifying unit 26 (see FIG. 1) of the main server 20 acquires the maximum discount information, which is the discount amount allowed by the service station, from the SS terminal 51 (see FIG. 1) of the service station (step S23).
Further, the main server 20 compares the provisional discount information associated with the user ID related to a certain service station with the maximum discount information acquired from the SS terminal 51 of the service station (step S24).
When the provisional discount information exceeds the maximum discount information, the main server 20 associates the maximum discount information with the user ID and records it in the discount database 32 (user database 31 in this example) (step S25). When the provisional discount information is less than the maximum discount information, the main server 20 associates the provisional discount information with the user ID and records it in the discount database 32 (step S26).

図５および図６を用いて値引き額の決定方法の具体例を説明する。図５は仮値引きデータベース３３の一例であり、図６は最大値引き情報の一例である。図５に示したように、仮値引き特定部２５には、ユーザＩＤ：ＡＡＡＡ０について利用ＳＳ（利用サービスステーション）は品川であり、仮値引き額は５円であると仮値引き額が特定されている。一方で図６に示したように、品川サービスステーションでは最大値引き額が４円に設定されている。そこでメインサーバ２０は、ユーザＩＤ：ＡＡＡＡ０の仮値引き額と最大値引き額を比較し、値引き額を最大値引き額の４円と特定し、ユーザＩＤ：ＡＡＡＡ０の値引き額は４円とユーザデータベース３１に記録する。
一方で図５に示したように、ユーザＩＤ：ＡＡＡＡ１の利用ＳＳは新橋であり、その仮値引き額は４円であると仮値引き額が特定されている。図６に示したように、新橋サービスステーションでは最大値引き額が５円に設定されている。そこでメインサーバ２０は、ユーザＩＤ：ＡＡＡＡ１の値引き額は４円とユーザデータベース３１に記録する。 A specific example of the method of determining the discount amount will be described with reference to FIGS. 5 and 6. FIG. 5 is an example of the provisional discount database 33, and FIG. 6 is an example of the maximum discount information. As shown in FIG. 5, in the provisional discount specifying unit 25, the provisional discount amount is specified as the user ID: AAAA0, the user SS (service station used) is Shinagawa, and the provisional discount amount is 5 yen. .. On the other hand, as shown in FIG. 6, the maximum discount amount is set to 4 yen at the Shinagawa service station. Therefore, the main server 20 compares the provisional discount amount of the user ID: AAAA0 with the maximum discount amount, specifies the discount amount as the maximum discount amount of 4 yen, and the discount amount of the user ID: AAAA0 is 4 yen in the user database 31. Record.
On the other hand, as shown in FIG. 5, the SS used by the user ID: AAAA1 is Shimbashi, and the provisional discount amount is specified to be 4 yen. As shown in FIG. 6, the maximum discount amount is set to 5 yen at the Shinbashi service station. Therefore, the main server 20 records the discount amount of the user ID: AAAA1 as 4 yen in the user database 31.

このように、本実施形態によれば、サービスステーションの事情も考慮した上でユーザに対する割引額を設定することができる。つまり、ユーザ、燃料元売り会社、サービスステーションの三社にとって都合のよい割引額を設定することができる。 As described above, according to the present embodiment, the discount amount for the user can be set in consideration of the circumstances of the service station. That is, it is possible to set a discount amount that is convenient for the user, the fuel source sales company, and the service station.

なお上述した説明では、値引き情報がユーザデータベース３１に記録され、コード情報の生成時にメインサーバ２０がユーザデータベース３１から値引き情報を読み出すように構成された例を説明したが、本発明はこれに限られない。ユーザデータベース３１には購入履歴のみが記録されており、メインサーバ２０が必要時に都度ユーザデータベース３１から購入履歴を読み出し、該購入履歴に基づき値引き情報を算出するように構成してもよい。値引き情報は、図４から図６を用いた方法にて算出することができる。 In the above description, the discount information is recorded in the user database 31, and the main server 20 is configured to read the discount information from the user database 31 when the code information is generated. However, the present invention is limited to this. I can't. Only the purchase history is recorded in the user database 31, and the main server 20 may be configured to read the purchase history from the user database 31 each time necessary and calculate the discount information based on the purchase history. The discount information can be calculated by the method using FIGS. 4 to 6.

以上、本発明の実施形態について説明をしたが、本発明の技術的範囲が本実施形態の説明によって限定的に解釈されるべきではないのは言うまでもない。本実施形態は単なる一例であって、特許請求の範囲に記載された発明の範囲内において、様々な実施形態の変更が可能であることが当業者によって理解されるところである。本発明の技術的範囲は特許請求の範囲に記載された発明の範囲及びその均等の範囲に基づいて定められるべきである。 Although the embodiments of the present invention have been described above, it goes without saying that the technical scope of the present invention should not be construed as being limited by the description of the present embodiments. It is understood by those skilled in the art that the present embodiment is merely an example, and various embodiments can be modified within the scope of the invention described in the claims.
