Description

This disclosure relates to data processing technology, and in particular to an information processing system and an information processing method.

A service has been proposed that allows a lease contract holder to receive a discount on fuel costs when refueling a vehicle leased to the lease contract holder by a car leasing company using the lease holder's own credit card (see, for example, Patent Document 1).

JP 2018-200711 A

Because it is a violation of the terms of the credit card for anyone other than the contract holder of a car lease contract to use the contract holder's credit card, in order to receive a discount on the fuel price, the contract holder must refuel the car themselves. The inventors felt that there was room for improvement to increase convenience for car lease users.

This disclosure has been made in light of these circumstances, and one of its objectives is to provide technology that improves convenience for car leasing users.

To solve the above problem, an information processing system according to one aspect of the present disclosure includes a memory unit that stores information about a personal card, which is a credit card of the user who has entered into a car lease contract, and information about a family card, which is an additional card that is issued in association with the personal card and used by a family member of the user; a reception unit that receives information indicating that a product at a service station has been purchased using the personal card or the family card; and a derivation unit that derives the amount to be charged to the user based on the total amount of product purchased at the service station using the personal card and the amount of product purchased at the service station using the family card, and based on predetermined discount rules.

Another aspect of the present disclosure is an information processing method. In this method, a computer having a memory unit that stores information about a personal card, which is a credit card of the user who has entered into a car lease contract, and information about a family card, which is an additional card that is issued in association with the personal card and used by a family member of the user, executes the steps of accepting information indicating that a product at a service station has been purchased using the personal card or the family card, and deriving the amount to be charged to the user according to the total amount of the product purchased at the service station by the personal card and the amount of the product purchased at the service station by the family card and a predetermined discount rule.

In addition, any combination of the above components, or any conversion of the expressions of this disclosure between devices, computer programs, recording media on which computer programs are recorded, etc., are also valid aspects of this disclosure.

This disclosure can improve convenience for car leasing users.

FIG. 4 is a diagram showing an example of fuel sales information stored in a fuel sales information storage unit;

The subject of the device or method of the present disclosure includes a computer. The computer executes a computer program to realize the functions of the subject of the device or method of the present disclosure. The computer includes, as its main hardware configuration, a processor that operates according to a computer program. The type of processor is not important as long as it can realize the functions by executing a computer program. The processor is composed of one or more electronic circuits including a semiconductor integrated circuit (IC, LSI, etc.). The computer program is recorded on a non-transitory recording medium such as a computer-readable ROM, optical disk, or hard disk drive. The computer program may be stored in advance on the recording medium, or may be supplied to the recording medium via a wide area communication network including the Internet.

The technology of the present disclosure will be described below with reference to the drawings based on preferred embodiments. The embodiments are illustrative and do not limit the invention, and all features and combinations thereof described in the embodiments are not necessarily essential to the invention. The same or equivalent components, members, and processes shown in each drawing are given the same reference numerals, and duplicated descriptions are omitted as appropriate. In addition, the scale and shape of each part shown in each drawing are set for convenience to facilitate explanation, and are not to be interpreted as being limiting unless otherwise specified. In addition, when terms such as "first" and "second" are used in this specification or claims, they do not represent any order or importance, but are intended to distinguish one configuration from another, unless otherwise specified.

First, an overview of the embodiment will be described. Conventionally, a service has been proposed that allows a discount on fuel costs to be received when a vehicle (hereinafter referred to as a "lease vehicle") rented from a car leasing company to a contract holder of a car leasing contract (hereinafter referred to as a "user") is refueled using the contract holder's own credit card. However, the fuel cost discount is limited to leased vehicles. In addition, since it is a violation of the credit card terms and conditions for someone other than the user who is the contract holder of a car leasing contract to refuel, the user himself/herself needs to refuel in order to receive the discount on the fuel cost.

In the fuel sales system of the embodiment, the scope of the fuel price discount is expanded, and the fuel price discount is applied to the entire household of the car lease contract holder (the user household, described below). Specifically, the fuel price discount is not limited to cases where fuel is filled up with the credit card of the user who is the car lease contract holder (hereinafter also referred to as the "personal card"), but is also applied when fuel is filled up with a family card attached to the personal card. A family card is an additional card issued in association with the personal card based on the user's application, and is an additional card used by the user's family members (for example, the user's spouse, children over 18 years old, or parents after retirement). Normally, the amount used on the family card is treated as being integrated with the personal card.

For example, if a family member of a user, rather than the user who signed the car lease contract, fills up a leased vehicle at a service station, and purchases fuel using a family card, the user can receive a discount on the fuel price even when the user is not present. This increases convenience for car lease users.

A service station (hereinafter also referred to as "SS") is a store that sells energy sources as products. An energy source is a resource used to drive a power source, and is provided, for example, to drive a moving body such as an automobile. Energy sources include vehicle fuel (gasoline, diesel, hydrogen, etc.), as well as kerosene and electricity. Examples of service stations include gas stations, hydrogen stations, charging stations, etc. A product is any tangible or intangible thing that is traded for or without payment, and is a concept that includes the provision of services. In the embodiment, an example of purchasing fuel for a vehicle at a service station is shown, but the technical concept of the present disclosure is broadly applicable to the purchase of products sold at service stations (for example, the various energy sources mentioned above).

In addition, in the fuel sales system of the embodiment, the vehicles eligible for the fuel price discount are not limited to leased vehicles. For example, when the user who has signed a car lease contract uses his/her personal card, and when the user's family member uses a family card, the fuel price discount is not limited to refueling leased vehicles, but also applies to refueling vehicles other than leased vehicles (for example, vehicles owned by the user's household, hereinafter also referred to as "non-leased vehicles"). This further increases convenience for car lease users. Also, since non-leased vehicles, in addition to leased vehicles, visit SSs more frequently, opportunities for fuel and non-oil sales at SSs can be expanded.

The details of the embodiment will be described. FIG. 1 shows the configuration of a fuel sales system 10 of the embodiment. The fuel sales system 10 includes a store system 20, a fuel sales management system 22, a car lease management system 24, and a billing management system 26. These devices are connected via a communication network including a LAN, a WAN, the Internet, etc.

A leased vehicle 12 and a non-leased vehicle 14 are used in the household of a user who has entered into a car leasing contract with a car leasing company. The user holds a personal card 16, and the user's family members, the spouse and children, hold family cards 18a and 18b (collectively referred to as "family cards 18"). The user, spouse and children use their own credit cards (personal card 16, family card 18a, family card 18b) to purchase fuel for the leased vehicle 12 and non-leased vehicle 14 at a gas station.

A store system 20 is installed in the SS. The store system 20 is an information processing system that manages sales and other matters at the SS. The store system 20 transmits refueling data relating to fuel purchased by a user using the personal card 16, or refueling data relating to fuel purchased by the user's family using the family card 18, to a fuel sales management system 22. Note that while FIG. 1 shows one SS (store system 20), an actual fuel sales system 10 will have multiple SSs (store systems 20).

The car lease center is provided with a car lease management system 24. The car lease management system 24 is an information processing system that processes data related to car lease contracts and fuel benefit applications. The car lease management system 24 transmits fuel benefit information related to fuel benefit recipients who have applied for a fuel benefit (in other words, a fuel price discount benefit) to the fuel sales management system 22.

The credit card company is provided with a billing management system 26. The billing management system 26 is an information processing system that manages billing to credit card contract holders.

The fuel sales management system 22 is an information processing system that manages information related to the sale of fuel at a gas station, in other words, manages information related to purchasers who purchase fuel at a gas station, and also manages the billing of fuel fees to purchasers. The fuel sales management system 22 transmits fuel billing data to the billing management system 26 to bill the user collectively for the cost of fuel purchased by the user and his/her family.

There are no limitations on the physical configuration of the store system 20, fuel sales management system 22, car lease management system 24, and billing management system 26 in FIG. 1. For example, each system may be realized by a single information processing device, or may be realized by multiple information processing devices working together.

Figure 2 is a block diagram showing the functional blocks of the fuel sales management system 22 in Figure 1. The fuel sales management system 22 includes a control unit 30, a memory unit 32, and a communication unit 34. The control unit 30 executes various data processing. The memory unit 32 stores data referenced or updated by the control unit 30. The communication unit 34 communicates with external devices according to a predetermined communication protocol. The control unit 30 transmits and receives data to and from the store system 20, the car lease management system 24, and the billing management system 26 via the communication unit 34.

The storage unit 32 includes a fuel sales information storage unit 36 and a discount rule storage unit 38. The fuel sales information storage unit 36 stores fuel sales information. The fuel sales information includes information about the personal card, which is the credit card of the user who entered into the car lease contract, and information about the family card linked to the personal card. Figure 3 shows an example of fuel sales information stored in the fuel sales information storage unit 36. The fuel sales information is information that associates a customer number, a parent number, a credit card number, a date of birth, a fuel purchase quantity, and a fuel purchase price.

The customer number can also be called a customer identification number, and is a number specific to each individual (for example, each of the user and his/her family). The customer number can also be called a number that is unique to each individual. The customer number of a car lease contract holder (personal card holder) and the customer number of his/her family (family card holder) have different values in the last digit, but the values of the other digits are the same. The parent number is information for linking the personal card and the family card, and is specifically the customer number of the personal card holder corresponding to the family card holder. Records 50 and 56 in FIG. 3 are records related to the car lease contract holder (personal card holder). Meanwhile, records 52, 54, and 58 in FIG. 3 are records related to the family members (family card holders) of the car lease contract holder.

The credit card number is the card number of the personal card and the family card. The date of birth is the birth date of each individual. The fuel purchase quantity is the quantity of fuel (in liters) purchased by each individual using either the personal card or the family card. The fuel purchase amount is the purchase amount (in yen) of fuel purchased by each individual using either the personal card or the family card. The fuel purchase quantity and fuel purchase amount may be cumulative values of the unbilled fuel cost, and may be cleared when the fuel cost is billed.

Returning to FIG. 2, the discount rule storage unit 38 stores a first discount rule regarding fuel costs for the household of the user who has signed a car lease contract (in other words, the user and his/her family). The first discount rule stipulates that the discount applies to the total amount of fuel purchased using the user's personal card and the amount of fuel purchased using the family card, up to a predetermined upper limit of the purchase quantity. The upper limit is, for example, 100L.

The control unit 30 includes a card information reception unit 40, a refueling data reception unit 42, a fuel bonus information reception unit 44, a billing amount derivation unit 46, and a billing unit 48. The functions of these multiple functional blocks may be implemented in a computer program. This computer program may be stored on a recording medium, or may be installed in the storage of the fuel sales management system 22 via the recording medium. Alternatively, the computer program may be installed in the storage of the fuel sales management system 22 via a network. The CPU of the computer of the fuel sales management system 22 may perform the functions of the multiple functional blocks of the control unit 30 by reading the computer program into main memory and executing it.

The card information acceptance unit 40 accepts card information related to credit cards issued by credit card companies, sent from the credit card company's device. The card information includes customer number, parent number, credit card number, and date of birth as information related to the principal's card and family card. The card information acceptance unit 40 stores the accepted card information in the fuel sales information storage unit 36.

The refueling data reception unit 42 receives refueling data transmitted from the SS store system 20, including information indicating that fuel for a vehicle has been purchased using a personal card or a family card. The refueling data includes various data read from the customer's credit card by the SS's information terminal, including at least the customer number, the fuel purchase quantity (also referred to as the fuel sales quantity), and the fuel purchase price (also referred to as the fuel sales price). The refueling data reception unit 42 refers to the fuel sales information storage unit 36 to identify a record of fuel sales information including the customer number indicated by the refueling data, and increases the values of the fuel purchase quantity and fuel purchase price of the identified record by the fuel purchase quantity and fuel purchase price indicated by the refueling data.

The fuel bonus information reception unit 44 receives fuel bonus information sent from the car lease management system 24 of the car lease center. The fuel bonus information includes information about each car lease contract holder who is to receive a discount on the fuel price, and in the embodiment, includes a customer number, date of birth, and a set of second discount rules. The second discount rules may include a discount rate or discount amount. For example, the second discount rules may stipulate a discount of 5 to 10 yen per liter of fuel. The second discount rules may also include a different discount rate or discount amount for each car lease contract holder (in other words, for each customer number).

The billing amount derivation unit 46 derives the billing amount for fuel to each car lease contract holder. The billing amount derivation unit 46 derives the sum of the fuel purchase quantity by the personal card and the fuel purchase quantity by the family card stored in the fuel sales information storage unit 36 for each user's household (a set of the personal card and the family card) (hereinafter also referred to as the "household fuel purchase quantity"). The billing amount derivation unit 46 also derives the sum of the fuel purchase amount by the personal card and the fuel purchase amount by the family card stored in the fuel sales information storage unit 36 for each user's household (a set of the personal card and the family card) (hereinafter also referred to as the "household fuel purchase amount").

The billing amount derivation unit 46 derives the billing amount for the user for each user household based on the household fuel purchase quantity, the household fuel purchase amount, the first discount rule stored in the discount rule storage unit 38, and the second discount rule indicated by the fuel benefit information.

The billing unit 48 executes a process of billing the user for the fuel cost billed to the user derived by the billing amount derivation unit 46. Specifically, the billing unit 48 transmits fuel cost billing data including the credit card number of the user's personal card and the fuel cost billed to the user derived by the billing amount derivation unit 46 to the billing management system 26.

The operation of the fuel sales system 10 having the above configuration will now be described with reference to FIG.
A user applies to a credit card company for issuance of a credit card (personal card and family card), and the credit card company issues a personal card 16 for the user, a family card 18a for the user's spouse, and a family card 18b for the user's child. The user enters into a car lease contract with a car lease company, and at that time also applies for a fuel benefit (fuel price discount benefit). A leased vehicle 12 is provided to the user household based on the car lease contract. In addition to the leased vehicle 12, the user household also owns a non-leased vehicle 14.

The credit card company's device transmits card information relating to the issued principal card 16, family card 18a, and family card 18b to the fuel sales management system 22. The card information reception unit 40 of the fuel sales management system 22 receives the card information and stores the contents of the card information (e.g., customer number, parent number, credit card number, date of birth) in the fuel sales information storage unit 36.

The user uses the personal card 16 at an SS to purchase fuel and refuel the leased vehicle 12. The user also uses the personal card 16 at an SS to purchase fuel and refuel the non-leased vehicle 14. Similarly, the user's spouse (or child) uses the family card 18a (or family card 18b) at an SS to purchase fuel and refuel the leased vehicle 12. The user's spouse (or child) also uses the family card 18a (or family card 18b) at an SS to purchase fuel and refuel the non-leased vehicle 14.

Each time fuel is purchased at a gas station, the gas station store system 20 transmits refueling data including the fuel purchase quantity, fuel purchase price, and card information (customer number, etc.) used to purchase the fuel to the fuel sales management system 22. The refueling data reception unit 42 of the fuel sales management system 22 receives the refueling data and identifies a record in the fuel sales information storage unit 36 specified by the card information indicated by the refueling data. The refueling data reception unit 42 adds the values indicated by the refueling data to the values of the fuel purchase quantity and fuel purchase price of the identified record.

Record 50 in FIG. 3 is a record related to the user in FIG. 1 (personal card 16). Record 50 indicates that 50 L of fuel was purchased using personal card 16 for a purchase amount of 7,000 yen. Record 52 in FIG. 3 is a record related to the spouse (family card 18a) of the user in FIG. 1. Record 52 indicates that 30 L of fuel was purchased using family card 18a for a purchase amount of 4,200 yen. Record 54 in FIG. 3 is a record related to the child (family card 18b) of the user in FIG. 1. Record 54 indicates that 40 L of fuel was purchased using family card 18b for a purchase amount of 5,600 yen.

The car lease management system 24 of the car lease center periodically transmits fuel bonus information related to the recipient of the fuel price discount (in this embodiment, the car lease contract holder) to the fuel sales management system 22 at a predetermined timing. The fuel bonus information reception unit 44 of the fuel sales management system 22 receives the fuel bonus information. The fuel bonus information here includes the customer number of the user in FIG. 1, and also sets a discount of 10 yen per liter as the second discount rule.

The billing amount derivation unit 46 of the fuel sales management system 22 derives the household fuel purchase quantity, which is the sum of the fuel purchase quantity by the personal card and the fuel purchase quantity by the family card stored in the fuel sales information storage unit 36, for each user's household (a pair of corresponding personal card and family card). The billing amount derivation unit 46 also derives the household fuel purchase amount, which is the sum of the fuel purchase amount by the personal card and the fuel purchase amount by the family card stored in the fuel sales information storage unit 36, for each user's household (a pair of corresponding personal card and family card).

The billing amount derivation unit 46 identifies the user household in FIG. 1 as eligible for the discount based on the customer number of the user in FIG. 1 indicated in the fuel benefit information. The billing amount derivation unit 46 derives 120L, which is the sum of the fuel purchase quantities in records 50, 52, and 54 in FIG. 3, as the household fuel purchase quantity for the user household in FIG. 1. The billing amount derivation unit 46 also derives 16,800 yen, which is the sum of the fuel purchase amounts in records 50, 52, and 54 in FIG. 3, as the household fuel purchase amount for the user household in FIG. 1.

Here, the first discount rule stored in the discount rule storage unit 38 of the fuel sales management system 22 specifies that the discount applies up to an upper limit of 100 L of fuel. The billing amount derivation unit 46 specifies that 100 L of fuel is subject to the discount out of the household fuel purchase quantity of 120 L of the user household in FIG. 1. Also, as described above, the discount unit price determined by the fuel benefit information is 10 yen/L. The billing amount derivation unit 46 derives 15,800 yen, which is the amount obtained by discounting 1,000 yen (i.e., the discount unit price of 10 yen/L x 100 L) from the household fuel purchase amount, as the billing amount for the user in FIG. 1.

Note that record 56 in FIG. 3 corresponds to the personal card of the car lease contract holder not shown in FIG. 1, and record 58 in FIG. 3 corresponds to the family card of the family of the car lease contract holder. In this case, the billing amount derivation unit 46 derives 70L as the household fuel purchase quantity of the car lease contract holder, and derives 9,800 yen as the household fuel purchase amount. The billing amount derivation unit 46 subjects the entire household fuel purchase quantity (70L) to the discount. The billing amount derivation unit 46 derives 9,100 yen, which is the amount obtained by deducting 700 yen (i.e., discount unit price 10 yen/L x 70L) from the household fuel purchase amount, as the billing amount to be paid to the car lease contract holder.

The billing unit 48 of the fuel sales management system 22 transmits fuel billing data, including the credit card number of the user's personal card 16 and the billing amount to the user derived by the billing amount derivation unit 46, to the billing management system 26 of the credit card company. The billing management system 26 executes a process of billing the user for the total amount of the billing amount indicated by the fuel billing data and other billing amounts according to the use of the personal card 16 and the family card 18.

According to the fuel sales system 10 of the embodiment, the discount on the fuel price is applied when the family of the car lease contract holder uses a family card to purchase fuel, and also when refueling a non-leased vehicle. This further enhances the convenience of the car lease user. It also reduces the risk of a person other than the car lease contract holder using the car lease contract holder's credit card, resulting in a violation of the credit card terms and conditions. In other words, it reduces the risk of the car lease contract holder's credit card being reused or used fraudulently. In addition to leased vehicles, non-leased vehicles will visit the SS more frequently, which will increase the opportunities for fuel sales and non-oil sales at the SS. In addition, by setting an upper limit on the fuel purchase quantity to which the discount is applied, it is possible to prevent the discount from being applied indefinitely and ensure the feasibility of the fuel price discount.

Next, the process will be described when the user in FIG. 1 enters into multiple car lease contracts (here, a first car lease contract and a second car lease contract). In the fuel sales system 10, a first principal card and a first family card corresponding to the first car lease contract are issued, and a second principal card (a principal card different from the first principal card) and a second family card (a family card different from the first family card) corresponding to the second car lease contract are also issued. The fuel sales information storage unit 36 of the fuel sales management system 22 stores information on the first principal card and the first family card, and information on the second principal card and the second family card. For example, the fuel sales information storage unit 36 stores two sets of records corresponding to records 50, 52, and 54 in FIG. 3.

The billing amount derivation unit 46 of the fuel sales management system 22 derives a first billing amount to the user based on the total amount of fuel purchased by the first principal card and the first family card, and in accordance with the first discount rule and the second discount rule. The billing amount derivation unit 46 also derives a second billing amount to the user based on the total amount of fuel purchased by the second principal card and the second family card, and in accordance with the first discount rule and the second discount rule. That is, the billing amount derivation unit 46 applies a discount up to a predetermined upper limit (e.g., 100 L) to the fuel purchases by the principal card and the family card corresponding to each contract for each car lease contract.

The billing unit 48 of the fuel sales management system 22 transmits first fuel billing data including the credit card number of the first principal card and the first billing amount to the billing management system 26. The billing unit 48 also transmits second fuel billing data including the credit card number of the second principal card and the second billing amount to the billing management system 26. This causes the user to be billed for the discounted billing amount for the fuel purchase using the first principal card and the first family card, and the discounted billing amount for the fuel purchase using the second principal card and the second family card.

According to this embodiment, the more car lease contracts a car lease user enters into, the greater the fuel price discount he or she can enjoy. For example, if the fuel price discount is 100L when one car lease contract is entered into, the fuel price discount increases to 200L when two car lease contracts are entered into. This provides users with an incentive to enter into many car lease contracts, and promotes the use of car leases.

The present disclosure has been described above based on examples. These examples are merely illustrative, and it will be understood by those skilled in the art that various modifications are possible in the combination of each component or each processing process, and that such modifications are also within the scope of the present disclosure.

A modified example will be described. In the above embodiment, when a user enters into multiple car lease contracts, a discount up to a predetermined upper limit is applied to fuel purchases made with the personal card and family card corresponding to each contract for each car lease contract. As a modified example, even when a user enters into multiple car lease contracts, there may be only one set of a personal card held by the user and a family card held by the user's family. In this case, the first discount rule stored in the discount rule storage unit 38 may stipulate that the upper limit of the fuel purchase quantity subject to discount is increased according to the number of car lease contracts entered into by the user.

In this variant, the fuel bonus information sent from the car lease management system 24 of the car lease center to the fuel sales management system 22 may include the number of car lease contracts concluded by the user. The billing amount derivation unit 46 of the fuel sales management system 22 may increase the upper limit of the fuel purchase quantity subject to discount the greater the number of car lease contracts concluded by the user indicated by the fuel bonus information. For example, the upper limit may be 100L when there is one car lease contract, 200L when there are two car lease contracts, and 300L when there are three car lease contracts.

For example, if a certain user has two car lease contracts and the user's household fuel purchase quantity is 200L, the billing amount derivation unit 46 may discount all of the household fuel purchase quantity (200L). The billing amount derivation unit 46 may deduct 2,000 yen (i.e., discount unit price 10 yen/L x 200L) from the user's household fuel purchase amount. Even in this modified fuel sales system 10, the more car lease users enter into car lease contracts, the greater the fuel price discount they can enjoy. This provides users with an incentive to enter into many car lease contracts, and promotes the use of car leases.

Another modified example will be described. In the above embodiment, the first discount rule is stored in the discount rule storage unit 38 of the fuel sales management system 22, and the second discount rule is set in the fuel bonus information sent from the car lease management system 24 to the fuel sales management system 22, but the location (device, area) where the first discount rule and the second discount rule are stored or set is not limited to this. The first discount rule and the second discount rule may be stored or set in a location (device, area) that can be referenced when the billing amount derivation unit 46 of the fuel sales management system 22 derives the billing amount. For example, both the first discount rule and the second discount rule may be stored in the discount rule storage unit 38 of the fuel sales management system 22.

Any combination of the above-mentioned examples and modifications is also useful as an embodiment of the present disclosure. A new embodiment resulting from the combination will have the combined effects of each of the examples and modifications. It will also be understood by those skilled in the art that the functions to be performed by each of the constituent elements recited in the claims can be realized by each of the components shown in the examples and modifications alone or in combination with each other.
