Display control system, display control method, and program

Abstract

To improve user convenience. [Solution] The usage information acquisition unit (101) of the display control system (1) acquires usage information regarding the user's use of a predetermined service. The grant rate determination unit (102) determines, based on the usage information, a grant rate for benefits granted by using a predetermined payment method, which fluctuates depending on whether the user meets predetermined grant rate conditions and is finalized at a predetermined confirmation timing. The display control unit (103) causes the user's terminal (20) to display a grant rate screen showing the grant rate and a status indicating whether the grant rate has been finalized or not.

Description

【Technical Field】 【0001】 The present disclosure relates to a display control system, a display control method, and a program. 【Background Art】 【0002】 Conventionally, there is known a settlement service in which a grant rate regarding a privilege granted to a user varies according to whether the user satisfies a predetermined grant rate condition. For example, in Patent Document 1, a service providing device is described that determines a grant rate applied to a user after the expiration of a predetermined period based on the total amount of the amount paid by the user in a first payment method during a predetermined period and the amount paid by the user in a second payment method during a predetermined period (an example of a grant rate condition). 【Prior Art Documents】 【Patent Documents】 【0003】 【Patent Document 1】 Japanese Patent No. 7329160 【Summary of the Invention】 【Problems to be Solved by the Invention】 【0004】 However, in the technique of Patent Document 1, the grant rate is only determined after the expiration of a predetermined period, and the user cannot know the grant rate applied to himself / herself and the status regarding whether the grant rate is determined. Therefore, the technique of Patent Document 1 could not improve the convenience of the user. This is not limited to the settlement service in which the grant rate condition is determined as in Patent Document 1, but is the same for other settlement services. The conventional technique could not improve the convenience of the user. 【0005】 One object of the present disclosure is to improve the convenience of the user. 【Means for Solving the Problems】 【0006】 The display control system relating to this disclosure includes: a usage information acquisition unit that acquires usage information relating to a user's use of a predetermined service; a grant rate determination unit that determines a grant rate relating to benefits granted by the use of a predetermined payment method, which fluctuates depending on whether the user meets predetermined grant rate conditions and is determined at a predetermined determination timing, based on the usage information; and a display control unit that causes the user terminal of the user to display a grant rate screen showing the grant rate and a status indicating whether the grant rate has been determined or not. [Effects of the Invention] 【0007】 This disclosure can improve user convenience.

Hardware configuration of the display control system] An example of an embodiment of the display control system, display control method, and program related to this disclosure will be described. Figure 1 is a diagram showing an example of the hardware configuration of the display control system. For example, the display control system 1 includes a payment server 10 and a user terminal 20. Each of the payment server 10 and the user terminal 20 is connected to a network N such as the Internet or a LAN. At least one of the payment server 10 and the user terminal 20 may be present in multiple units. 【0010】 The payment server 10 is a server computer for payment services. The payment service is a service that provides electronic payments (cashless payments) to users. For example, the payment server 10 includes a control unit 11, a storage unit 12, and a communication unit 13. The control unit 11 includes at least one processor. The storage unit 12 includes at least one of volatile memory such as RAM and non-volatile memory such as flash memory. The communication unit 13 includes at least one of a communication interface for wired communication and a communication interface for wireless communication. 【0011】 The user terminal 20 is the user's computer. For example, the user terminal 20 is a smartphone, tablet, personal computer, or wearable device. The user terminal 20 includes a control unit 21, a storage unit 22, a communication unit 23, an operation unit 24, and a display unit 25. The hardware configuration of the control unit 21, the storage unit 22, and the communication unit 23 may be the same as that of the control unit 11, the storage unit 12, and the communication unit 13, respectively. The operation unit 24 is an input device such as a touch panel or a mouse. The display unit 25 is a display such as a liquid crystal or organic EL. 【0012】 Note that the programs stored in the storage units 12 and 22 may be supplied to the settlement server 10 or the user terminal 20 via the network N. Further, at least one of a reading unit (for example, a memory card slot) that reads a computer-readable information storage medium and an input / output unit (for example, a USB port) for inputting / outputting data to / from an external device may be included in the settlement server 10 or the user terminal 20. For example, a program stored in an information storage medium may be supplied to the settlement server 10 or the user terminal 20 via at least one of the reading unit and the input / output unit. 【0013】 Further, the display control system 1 may include at least one computer. The computer included in the display control system 1 is not limited to the example of FIG. 1. For example, the display control system 1 may include only the settlement server 10. In this case, the user terminal 20 exists outside the display control system 1. The display control system 1 may include the settlement server 10 and another computer not shown in FIG. 1 (for example, a point server described later). 【0014】 [2. Outline of Display Control System] In the present embodiment, a case where a user uses a settlement service from a settlement application stored in the user terminal 20 will be taken as an example. The settlement application is an application provided by the administrator of the settlement service. The user can use any settlement means in the settlement service. For example, the user may use electronic money, a balance not called electronic money, a credit card, a card other than a credit card, points, a bank account, an account other than a bank account, a cryptocurrency, a wallet, or other settlement means in the settlement service. Since the settlement means may be used for payment, it can also be called a payment means. 【0015】 For example, the user installs a payment app on the user terminal 20 and registers as a member of the payment service. After the user completes the membership registration of the payment service, the user can launch the payment app on the user terminal 20 to use the payment service. In addition, the user may use the payment service from an app other than the payment app stored in the user terminal 20 (for example, an app provided by a credit card company or other non-payment apps) or a browser. 【0016】 FIG. 2 is a diagram showing an example of a screen displayed on the user terminal 20. For example, when the user operates the user terminal 20 to launch the payment app, as shown on the left side of FIG. 2, the user terminal 20 causes the display unit 25 to display a top screen SC1 including a payment code C10 generated based on a payment code ID that can identify the user in the payment service. The payment code C10 is a code for payment. In the example on the left side of FIG. 2, the case where the payment code C10 includes a barcode and a two-dimensional code is described, but the payment code C10 may be either a barcode or a two-dimensional code. The process of generating the payment code C10 from the payment code ID may be executed either by the payment server 10 or the user terminal 20. 【0017】 In addition, the payment in the payment service may be executed by a method other than the method of causing the store terminal to read the payment code C10. For example, the payment may be of a type where the user terminal 20 reads a code displayed on the store terminal, a type where the user terminal 20 reads a code posted in the store, a type that is completed only by operations on the user terminal 20, a type that uses the IC chip of the user terminal 20, online payment (for example, account payment using the user's account or ID payment using the user's ID), carrier payment that is the payment of the carrier used by the user terminal 20, or other types. For another example, a payment may be executed where the user reads the code on the bill with the user terminal 20 and pays the bill. 【0018】 For example, the top screen SC1 includes a tab T11 for the user to switch the content displayed on the top screen SC1. When the user selects "Point Card" on tab T11, the user terminal 20 displays a point code C12, generated based on a point code ID that can identify the user in the point service, on the top screen SC1, as shown on the right side of Figure 2. The point service is a service that manages the points held by the user. In this embodiment, the case in which the point service is linked with the payment service is given as an example, but the point service may be one of the services in the payment service. The operator of the point service and the operator of the payment service may be the same or different from each other. The point service may be a service in which an account is used to manage the point balance without the use of a point card in particular. 【0019】 The example on the right side of Figure 2 illustrates the case where the point code C12 is a barcode, but the point code C12 may also be a two-dimensional code, or it may include both a barcode and a two-dimensional code. The process of generating the point code C12 from the point code ID may be performed by either the payment server 10 or the user terminal 20. If there is a point server, which is a server computer for the point service, separate from the payment server 10, this process may be performed by the point server. The process of issuing the point code ID may also be performed by the point server. 【0020】 In this embodiment, we take the example of a case where the payment code ID and the points code ID are different from each other, but the payment code ID and the points code ID may be the same from each other. That is, the user may be identified by a common code ID in both the payment service and the points service. In other words, the payment code C10 and the points code C12 may not be different from each other, but the same from each other. A common code may be used in both the payment service and the points service. 【0021】 For example, if the user selects "Code Payment" on tab T11 in the state shown on the right side of Figure 2, the system returns to the state shown on the left side of Figure 2. When the payment code C10 is read by the merchant terminal, which is the terminal of the payment service's participating merchant, the payment is executed. The payment process after the payment code C10 is read may be the same as that of a known payment service. For example, if a user reads the points code C12 at the merchant terminal and then reads the payment code C10 at the merchant terminal to execute the payment, points corresponding to the payment amount will be awarded to the user. 【0022】 Furthermore, even if a user reads the point code C12 at a merchant terminal and makes a payment using a payment method other than the payment service (e.g., cash, a physical card, or another payment service), points corresponding to the payment amount may still be awarded to the user. Some stores may handle products or services that are not eligible for points. The process after the point code C12 is read at the merchant terminal may be the same as the process in known point services. The point code C12 may also be read after the payment has been made. 【0023】 In this embodiment, the points awarded to the user are calculated based on the payment amount eligible for points and the point award rate. The award rate is sometimes called the reward rate. The number of points awarded to the user may be determined by rounding down the value obtained by multiplying the payment amount eligible for points by the award rate. The number of points awarded to the user may be determined by other calculation formulas. For example, rounding up or rounding to the nearest integer may be used instead of rounding down. The number of points awarded to the user may be determined by multiplying the value obtained by rounding down the payment amount eligible for points by the award rate. Rounding up or rounding to the nearest integer may be used instead of rounding down. The method for calculating the number of points may be publicly known. Points may be awarded to the user immediately or after a certain period of time has elapsed. 【0024】 For example, a common reward rate may be applied regardless of the type of payment method used from the payment app. However, in this embodiment, we will take the example where a dedicated reward rate is set for the electronic money available from the payment app (in the example on the left in Figure 2, "AAA Cash"). Hereafter, this reward rate will be referred to as the reward rate for electronic money usage. As shown on the left side of Figure 2, when a user makes a payment with electronic money set as the payment source, the reward rate for electronic money usage is applied. If a user makes a payment with another payment method such as a credit card set as the payment source, the reward rate for electronic money usage is not applied. 【0025】 In this embodiment, we take an example where the reward rate for electronic money usage is fixed and applied for each recurring application period. For example, the reward rate applied for a certain application period is fixed and applied according to the usage of the point service measured in the measurement period prior to that application period. The application period and the measurement period correspond one-to-one. That is, there is a measurement period for each application period. In this embodiment, we take an example where the application period is a different period from the measurement period, but the application period may be the same as the measurement period. All or part of the application period may overlap with all or part of the measurement period. The length of the application period may be the same as or different from the length of the measurement period. The application period and the measurement period may correspond one-to-many, many-to-one, or many-to-many. 【0026】 Figure 3 shows an example of the application period and measurement period. In the example in Figure 3, the application period is a month. That is, the application period is the period from the 1st of each month to the end of that month. The measurement period is the period from the 16th of the month two months prior to the application period to the 15th of the month one month prior to the application period. For example, the measurement period corresponding to the application period in March is from the 16th of January to the 15th of February. The measurement period corresponding to the application period in April is from the 16th of February to the 15th of March. The measurement period corresponding to the application period in May is from the 16th of March to the 15th of April. Note that the year is omitted in Figure 3. 【0027】 In this embodiment, we take an example where the reward rate for electronic money usage during a certain application period varies depending on the number of times the point service is used during the measurement period corresponding to that application period (for example, the number of times the point code C12, which is an electronic point card, is presented). For example, if the number of times the point service is used is less than a threshold, the reward rate for electronic money usage will be 0.5%. If the number of times the point service is used is equal to or greater than the threshold, the reward rate for electronic money usage will increase to 1.0%. The threshold can be any value. In this embodiment, we take the case where the threshold is 2 as an example, but the threshold may be 1 or 3 or more. 【0028】 In this embodiment, the reward rate for electronic money usage during a given application period is determined at the confirmation timing corresponding to that application period. The confirmation timing is the timing at which the reward rate is determined. The confirmation timing may be after the end of the measurement period, at the same time as the end of the measurement period, or before the end of the measurement period. There is a confirmation timing for each of the multiple application periods. The confirmation timing may be a predetermined timing or a dynamically determined timing. For example, the confirmation timing may be when the number of point card usages exceeds a threshold. 【0029】 In this embodiment, we take the example that the confirmation timing is after the measurement period has ended. The length from the end of the measurement period to the confirmation timing may be any length. In this embodiment, we take the example that the confirmation timing is the 27th of each month, but the confirmation timing may be any day from the 1st to the 26th of each month, or it may be after the 28th of each month. The confirmation timing may also be the timing at which the batch file that confirms the assignment rate is executed. The time of the confirmation timing may be any time. 【0030】 Furthermore, a reward rate may be set for when a user makes a payment using a payment app. Hereafter, this reward rate will be referred to as the reward rate for payment app usage. The reward rate for payment app usage is the reward rate for points awarded regardless of the payment method used by the user. The reward rate for electronic money usage is the reward rate added to the reward rate for payment app usage. The reward rate for electronic money usage can also be said to be the reward rate for bonus points that a user can earn by using electronic money. In this embodiment, we take the example where the reward rate for payment app usage is the same in all applicable periods, but the reward rate for payment app usage may vary depending on the applicable period. 【0031】 For example, suppose the reward rate for using a payment app is 0.5%. During a period when the reward rate for using electronic money is 0.5%, if a user makes a payment using electronic money through the payment app, the total reward rate will be 1.0%. During a period when the reward rate for using electronic money is 1.0%, if a user makes a payment using electronic money through the payment app, the total reward rate will be 1.5%. If a user makes a payment using a payment method other than electronic money through the payment app, the reward rate for using electronic money will not apply. Other payment methods do not necessarily have a defined reward rate, or they may have a separate reward rate specifically for them. In this embodiment, users can easily check information such as the reward rate for each applicable period. 【0032】 Figure 4 shows an example of a screen displayed on the user terminal 20 when the grant rate does not increase. In Figure 4, the color of the text is schematically represented by the presence or absence of an underline. Underlined text is a predetermined color (for example, red). Ununderlined text is a color other than the predetermined color (for example, black or gray). In the example in Figure 4, the current time is assumed to be one of the days from March 1st to 15th, which is part of the measurement period corresponding to the April application period. The current time is within the measurement period corresponding to the April application period. The measurement period corresponding to the May application period has not yet arrived. The grant rate for the March application period has been determined. The grant rates for the April application period and the May application period have not yet been determined. 【0033】 For example, in the state of the top screen SC1 in the upper left of Figure 4, if the user selects icon I13 to check the grant rate, the user terminal 20 will display the grant rate screen SC2 on the display unit 25, as shown in the upper right of Figure 4. This screen shows the application rate for each of the multiple application periods and the status of whether or not the application rate has been finalized. The grant rate screen SC2 includes tab T20A showing the application period for March, which is the current month; tab T20B showing the application period for April, which is the next month; and tab T20C showing the application period for May, which is two months later. In the examples in the upper right, lower left, and lower right of Figure 4, it is assumed that no increase in the grant rate occurs in any month. 【0034】 In the example in the upper right of Figure 4, tab T20B, which represents April, the applicable period corresponding to the current measurement period, is selected by default from tabs T20A to T20C. That is, when the reward rate screen SC2 is first displayed, tab T20B is selected from tabs T20A to T20C. Tab T20B, which is selected by default, is the tab that is selected by default when the reward rate screen SC2 is displayed. Tab T20B, which is selected by default, is the tab that is selected by default when icon I13 of the top screen SC1 is selected and the reward rate screen SC2 is displayed, or when transitioning to the reward rate screen SC2 from the link on the payment completion screen SC3 described later (for example, "How to set the reward rate to 1.5% >" in Figure 13). 【0035】 Hereafter, when tabs T20A to T20C are not distinguished, they will simply be referred to as tab T20. For example, the heading of tab T20 (the part that accepts operations for switching tab T20) includes the month indicating the applicable period corresponding to that tab T20, the grant rate during the applicable period, and an icon that is an example of the status of whether or not the grant rate during the applicable period has been determined (for example, an icon for "determined" or "not determined"). 【0036】 In the upper right example of Figure 4, the number of point card usages during the measurement period corresponding to the March application period is below the threshold. The reward rate during the March application period is 1.0%. The reward rate during the March application period is finalized. The heading of tab T20A includes text indicating that it is March, text indicating in red (underlined in the diagram) that the reward rate for March is 1.0%, and a "Finalized" icon indicating that the reward rate for March is finalized. 【0037】 In the upper right example of Figure 4, the number of point card usages during the measurement period corresponding to the April application period is below the threshold. The reward rate during the April application period is 1.0%. The reward rate during the April application period has not yet been determined. The heading of tab T20B includes text indicating that it is April, text indicating in gray (not underlined in the diagram) that the reward rate for April is 1.0%, and an "Undetermined" icon indicating that the reward rate for April has not yet been determined. 【0038】 In the upper right example of Figure 4, the number of point card usages during the measurement period corresponding to the May application period is below the threshold. The reward rate during the May application period is 1.0%. The reward rate during the May application period has not yet been determined. The heading of tab T20C includes text indicating that it is May, text indicating in gray (not underlined in the diagram) that the reward rate for May is 1.0%, and an "Undetermined" icon indicating that the reward rate for May has not yet been determined. 【0039】 In the example in the upper right of Figure 4, even if the assignment rate is 1.0%, the assignment rate for the confirmed March tab T20A heading is shown in red (underlined in the diagram). On the other hand, the assignment rates for the unconfirmed April tab T20B heading and the unconfirmed May tab T20C heading are shown in gray (not underlined in the diagram). Therefore, not only the icon in the tab T20 heading, but also the color of the assignment rate in the tab T20 heading is one of the elements that indicates whether or not the assignment rate has been confirmed. 【0040】 In the upper right example of Figure 4, tab T20B, which corresponds to the application period in April, includes a display area A200B showing the basic reward rate and a display area A201B showing the reward rate (undetermined reward rate) based on the number of times the point card was used during the measurement period (current measurement period) corresponding to the application period in April. The basic reward rate is the basic reward rate that applies to all users. For example, the basic reward rate is the sum of the reward rate for the payment app and the minimum reward rate for electronic money. In this embodiment, the minimum reward rate is the reward rate when the number of times the point card is used does not exceed a threshold. 【0041】 In the upper right example of Figure 4, the base reward rate of 1.0% is shown in red (underlined in the diagram). For example, if a user uses their point card two more times during the current measurement period, the reward rate for April will increase by 0.5%, then, as shown in the upper right of Figure 4, the "2 more times to achieve" bubble will point to the 0.5% increase in the reward rate. In the upper right example of Figure 4, the 0.5% is shown in gray (not underlined in the diagram). 【0042】 For example, below display area A201B, the message "Earn 1 point for every 200 yen spent with both AAA Pay and AAA Cash" is displayed. In the example in the upper right of Figure 4, the point accrual rate for payments made using the payment app is 0.5%, so 1 point is awarded for every 200 yen spent using the payment app. The point accrual rate for payments made using electronic money is also 0.5%, so 1 point is awarded for every 200 yen spent using electronic money when the payment source in the payment app is electronic money. 【0043】 For example, when a user selects tab T20A, the user terminal 20 displays information for the March application period within tab T20A, as shown in the lower left of Figure 4. Tab T20A includes a display area A200A showing the basic accrual rate and a display area A201B showing the accrual rate (confirmed accrual rate) based on the number of times the point card was used during the measurement period corresponding to the March application period. In the example in the lower left of Figure 4, the basic accrual rate of 1.0% is shown in red (underlined in the diagram). Since the number of times the point card was presented during the measurement period corresponding to the March application period is below the threshold, the string representing the 0.5% increase in the accrual rate is shown in gray (not underlined in the diagram), as shown in the lower left of Figure 4. Since the measurement period corresponding to the March application period has already passed, the bubble showing the remaining number of uses is not displayed. Below display area A201A, the message "Earn 1 point for every 200 yen spent with both AAA Pay and AAA Cash" is displayed, similar to the message below display area A201B. 【0044】 For example, when a user selects tab T20C, the user terminal 20 displays information for the May application period within tab T20C, as shown in the lower right of Figure 4. Tab T20C includes a display area A200C showing the basic accrual rate and a display area A201C showing the accrual rate (undetermined accrual rate) based on the number of times the point card is used during the measurement period corresponding to the May application period. In the example in the lower right of Figure 4, the 1.0% basic accrual rate is shown in red (underlined in the diagram). Since the measurement period corresponding to the May application period has not yet started, the string representing the 0.5% increase in the accrual rate is shown in gray (not underlined in the diagram), as shown in the lower right of Figure 4. The callout indicating the remaining number of uses is not displayed. Below display area A201C, the message "Earn 1 point for every 200 yen spent with both AAA Pay and AAA Cash" is displayed, similar to the messages below display areas A201A and A201B. 【0045】 Hereafter, when display areas A200A, A200B, and A200C are not distinguished, they will simply be referred to as display area A200. Similarly, when display areas A201A, A201B, and A201C are not distinguished, they will simply be referred to as display area A201. Display areas A200 and A201 may be openable and closable. Advertisements (such as banner ads like "AAA Mobile is a great deal!" in the upper right, lower left, and lower right examples of Figure 4) may be displayed below display area A201. The advertisements may be determined according to the reward rate. 【0046】 Figure 5 shows an example of a screen displayed on the user terminal 20 when the reward rate increases. In Figure 5, as in Figure 4, an example is given where the reward rate screen SC2 is displayed from March 1st to 15th. For example, if the number of times the point card has been used during the measurement period corresponding to the application period in April (the current measurement period) is above the threshold, then, as shown in the upper left of Figure 5, the heading of tab T20B corresponding to the application period in April will display a string indicating 1.5%, which is the increased reward rate, in gray (not underlined in the diagram). A callout such as "Achieved! Presented 2 times" indicating that the number of times the point card has been used is above the threshold will be displayed pointing to the string 0.5% in display area A201B. In the example in the upper left of Figure 5, the string 0.5% in display area A201B is shown in red (underlined in the diagram). 【0047】 For example, below display area A201B, the message "AAA Pay awards 1 point for every 100 yen spent" is displayed. In the example in the upper left of Figure 5, the point accrual rate for using the payment app is 0.5%, so 1 point is awarded for every 200 yen spent using the payment app. For this reason, a message such as "AAA Pay awards 1 point for every 200 yen spent" would also be acceptable, but in the example in the upper left of Figure 5, the message "AAA Pay awards 1 point for every 100 yen spent" is displayed based on a 1.0% accrual rate, which is the sum of the base accrual rate for using electronic money (the minimum accrual rate for using electronic money) and the 0.5% accrual rate for using the payment app. 【0048】 For example, below display area A201B, the message "AAA Cash: Earn 1 point for every 200 yen spent" is also displayed. In the upper left example of Figure 5, the point accrual rate for payments made using the payment app has increased by 0.5%, so for every 200 yen spent using electronic money when the payment source of the payment app is electronic money, the points earned from using electronic money increase by 1 point. In the upper left example of Figure 5, the message for this increase is displayed. Note that if a message such as "AAA Pay: Earn 1 point for every 200 yen spent" is displayed as the point accrual rate for payments made using the payment app, a message such as "AAA Pay: Earn 1 point for every 100 yen spent" may also be displayed as the point accrual rate for using electronic money. 【0049】 For example, in the state shown in the upper left of Figure 5, when the user selects display area A200B or A201B, the user terminal 20 opens display area A200B or A201B, as shown in the upper right of Figure 5. When display area A200B is opened, the breakdown of the basic reward rate is displayed. For example, when display area A200B is opened, the reward rate for payment app usage and the minimum reward rate for electronic money usage are displayed in gray (not underlined in the diagram). When display area A201B is opened, the reward rate conditions, which indicate that the reward rate increases when the number of point card usages exceeds a threshold, and information about the point service participating stores are displayed. 【0050】 For example, if the number of times the point card has been used during the measurement period corresponding to the March application period (the current application period) exceeds the threshold, the heading of tab T20A corresponding to the March application period will display a string in red (underlined in the diagram) indicating 1.5%, which is the increased rate added. When the user selects tab T20A, the display switches to tab T20A, as shown in the lower left of Figure 5. In the example in the lower left of Figure 5, the string 0.5% in display area A201A is shown in red (underlined in the diagram). In the example in the lower left of Figure 5, the callout indicating that the number of times the point card has been used exceeds the threshold is not displayed. 【0051】 For example, in the state shown in the lower left of Figure 5, if the user selects display area A200A or A201A, the user terminal 20 opens display area A200A or A201A, as shown in the lower right of Figure 5. When display area A200A is opened, the breakdown of the basic reward rate is displayed, similar to display area A200B. When display area A201A is opened, the conditions for increasing the reward rate and information about participating merchants for the point service are displayed, similar to display area A201B. At the bottom of display area A201A, the messages "AAA Pay awards 1 point for every 100 yen spent" and "AAA Cash awards 1 point for every 200 yen spent" are displayed, similar to the bottom of display area A201B. 【0052】 In the example in Figure 5, since it is before the start of the measurement period corresponding to the application period in May, the heading of tab T20C will be the same as in Figure 4. When tab T20C is selected, it will be displayed the same as the lower right of Figure 4. When the user selects display areas A200C and A201C of tab T20C, display areas A200C and A201C will open. The opened display area A200C may be generally the same as the opened display areas A200A and A200B. The opened display area A201C differs from the opened display area A200A in that the string "0.5%" is shown in gray and the measurement period is different, but in other respects it may be the same as the opened display area A200A. 【0053】 As described above, the display control system 1 of this embodiment displays an award rate screen SC2 on the user terminal 20, which can display the award rate for each of the multiple application periods and the status regarding whether or not the award rate for that application period has been determined. This makes it easier for the user to check the award rate for each application period and whether or not that award rate has been determined, so the display control system 1 can improve user convenience. The details of the display control system 1 will be described below. 【0054】 [3. Functions implemented by the display control system] Figure 6 shows an example of the functions implemented by the display control system 1. The various components implemented in the display control system 1 of this embodiment can be configured by combining them into a single device or by further distributing them among multiple devices. 【0055】 [3-1. Functions implemented by the payment server] For example, the payment server 10 includes a data storage unit 100, a usage information acquisition unit 101, a grant rate determination unit 102, and a display control unit 103. The data storage unit 100 is implemented by a storage unit 12. The usage information acquisition unit 101, the grant rate determination unit 102, and the display control unit 103 are each implemented by a control unit 11. 【0056】 [Data Storage Unit] The data storage unit 100 stores various data related to at least one of the payment service and the point service. For example, the data storage unit 100 stores the payment database DB1, the point database DB2, and the point accrual rate data DT. 【0057】 Figure 7 shows an example of a payment database DB1. The payment database DB1 is a database that stores various information related to the payment service. For example, the payment database DB1 stores user ID, login account, password, payment code ID, expiration date, payment method information, payment source information, charge source information, and usage information for the payment service. The information stored in the payment database DB1 is not limited to the example in Figure 7. Other information may be stored in the payment database DB1. For example, the payment database DB1 may store at least one of the award rate determined by the award rate determination unit 102 and the award rate confirmed by the award rate determination unit 102. 【0058】 A user ID is an example of user identification information that can identify a user. A login account is also an example of user identification information. A login account is user identification information that a user enters to log in to a payment service. The login account may be freely changed by the user. A user ID is user identification information that is managed separately from the login account. In this embodiment, we take the example of a case where there is a login account separate from the user ID (where there are at least two pieces of user identification information), but there may be only one piece of user identification information. That is, the user ID and login account do not have to be separate. A password is authentication information that is verified during login. The login account and password may also be the user's biometric information. 【0059】 A payment code ID is also an ID that can identify a user, and is therefore an example of user identification information. In this embodiment, we will take the case where the payment server 10 issues a payment code ID as an example. For example, when the payment server 10 issues a payment code ID for a user, it issues a new payment code ID so as not to overlap with other payment code IDs. The payment server 10 stores the new payment code ID and its expiration date in the payment database DB1, associating it with the user's user ID or login account. The expiration date may be determined by any method. For example, the expiration date may be a predetermined time after the issuance of the payment code ID. The payment server 10 may share the payment code ID and expiration date with the user terminal 20. 【0060】 The payment code ID may be issued at any time. For example, the payment server 10 may issue the payment code ID when the payment application is launched, when the expiration date has passed, when the user instructs it to issue the payment code ID, or at any other time. The payment code ID may be issued by another computer (for example, a server computer that performs authentication during payment) rather than by the payment server 10, or it may be issued by the user terminal 20. The payment code ID does not have to have an expiration date. For example, the payment code ID may be an ID that is valid semi-permanently without a specific expiration date. 【0061】 Payment method information is information that identifies a payment method. For example, payment method information may include credit card numbers, electronic money numbers, bank account information, or point card numbers. Payment source information is information that identifies the payment method selected as the payment source. The payment source is the payment method used to pay for goods or services handled by the store. Charge source information is information that identifies the payment method selected as the charge source. The charge source is the payment method that serves as the source of funds for the charge. Charging can be done to any payment method, such as electronic money. For example, a user can instruct a charge from a payment app. 【0062】 Payment method usage information is information that shows the usage status or usage history of a payment method. For example, payment method usage information may show the date and time of payment, the payment amount, the payment location, the number of points awarded by the payment (or the number of points that are scheduled to be awarded by the payment), the balance of electronic money etc. after payment, information on the payment method set as the payer, or a combination of these. Since payment methods are used not only for payments but also for charging, payment method usage information may show the charge amount, the date and time of charging, information on the payment method set as the charge source, or a combination of these. The payment server 10 may update the payment method usage information each time a payment method is used. 【0063】 Figure 8 shows an example of the points database DB2. The points database DB2 is a database that stores various information related to the points service. For example, the points database DB2 stores the user ID, point code ID, expiration date, the number of points held by the user, usage information in the points service, and the accrual rate for electronic money usage. The information stored in the points database DB2 is not limited to the example in Figure 8. Other information may be stored in the points database DB2. For example, the points database DB2 may store the login account and password for the user to log in to the points service, the accrual rate for payment app usage, the accrual rate according to other payment methods, or other information. 【0064】 In this embodiment, we take the case where the user ID for the payment service and the user ID for the points service are the same (where a common user ID is used for both the payment service and the points service), but the user ID for the payment service and the user ID for the points service may be different. If the user ID for the payment service and the user ID for the points service are different, a database showing their correspondence is stored in the data storage unit 100. This database may be stored in a computer or information storage medium other than the payment server 10. 【0065】 The points code ID is an ID that can identify a user, and is therefore an example of user identification information. In this embodiment, we will take the case where the payment server 10 issues the points code ID as an example. For example, when the payment server 10 issues a points code ID for a user, it issues a new points code ID so as not to overlap with other points code IDs. The payment server 10 stores the new points code ID and its expiration date in the payment database DB1, associating it with the user's user ID or login account. The expiration date may be determined by any method. For example, the expiration date may be a predetermined time after the issuance of the points code ID. 【0066】 The point code ID may be issued at any time. For example, the payment server 10 may issue the point code ID when the payment app is launched, when the expiration date has passed, when the user instructs it to issue the point code ID, or at any other time. The point code ID may be issued by another computer (for example, the computer for the points service) instead of the payment server 10. The point code ID does not have to have an expiration date. For example, the point code ID may be an ID that is valid semi-permanently without a specific expiration date. 【0067】 The number of points can also be considered the balance of points held by the user. When points are awarded to a user, the number of points increases. When a user makes a payment using points, the number of points decreases. The process by which a user uses points may be the same as that of publicly known point services. If physical point cards are used in addition to the payment app, a point card number that can identify the physical point card may be associated with the number of points and stored in the point database DB2. 【0068】 Usage information refers to information about a user's use of the points service. It can also be described as a user's usage status or history of the points service. In the example in Figure 2, an electronic points card is used, so the usage information can also be described as information about the user's use of the electronic points card. If a physical points card is used, the usage information can also be described as information about the user's use of the physical points card. 【0069】 For example, the usage information may include the date and time the point card was read, information about the store where the point card was read, the date and time points were awarded, the number of points awarded, the date and time the payment for point awarding was executed, the amount of the payment, the location of the payment, the date and time points were used, the number of points used, the store where points were used, the date and time of login to the point service, or other information. When a user uses the point service, the payment server 10 updates the user's usage information to show the specific details of the user's usage. 【0070】 For example, when a user has a merchant terminal read their point card, the payment server 10 updates the user's usage information to show the current date and time as the date and time the point card was read. When points are awarded to a user, the payment server 10 updates the user's usage information to show the current date and time as the date and time the points were awarded. When a user spends points, the payment server 10 updates the user's usage information to show the current date and time as the date and time the points were spent. If a user uses the point service in another form, the payment server 10 updates the user's usage information to show how the user used the point service. 【0071】 Furthermore, usage information may be updated by a computer other than the payment server 10 (for example, a computer for the points service). Usage information may also be managed by another computer. In this case, the payment server 10 only needs to obtain the usage information from the other computer. The same applies to other information contained in the points database DB2; other information may also be managed by another computer. The payment server 10 may obtain other information related to the points service from the other computer. In addition, the usage information may show the number of times the points card has been used for each measurement period. Information showing the number of times the points card has been used for each measurement period may be stored in the payment database DB1. 【0072】 The award rate stored in the points database DB2 is the award rate determined by the award rate determination unit 102. In this embodiment, the award rate for electronic money usage is stored in the points database DB2. For example, the points database DB2 may store the award rate determined by the award rate determination unit 102 for each measurement period. The points database DB2 may also store the award rate finalized by the award rate determination unit 102 for each application period. The award rate determination unit 102 may store in the payment database DB1 the award rate for each of the multiple application periods and a status indicating whether or not the award rate has been finalized, in association with each of these. 【0073】 Figure 9 shows an example of grant rate data DT. Grant rate data DT is data that defines the method for determining the grant rate. Grant rate data DT may be in any format. For example, grant rate data DT may be in table format, formula format, text format, all or part of a program, a configuration file referenced by a program, a machine learning model, or other format. Grant rate data DT shows the relationship between the grant rate conditions and the grant rate for electronic money usage. Details of the grant rate conditions will be described later. The content of grant rate data DT shall be specified by the administrator of the payment service or point service. 【0074】 The data stored in the data storage unit 100 is not limited to the examples above. The data storage unit 100 only needs to store various data for at least one of the payment service and the point service. For example, the data storage unit 100 may store data necessary for displaying the top screen SC1, the reward rate screen SC2, or other screens. The data storage unit 100 may also store calculation formulas used in the calculation of benefits described later. 【0075】 [Usage information acquisition department] The usage information acquisition unit 101 acquires usage information regarding a user's use of a predetermined service. The predetermined service is a service in which usage information is referenced for determining or confirming the award rate. In this embodiment, the case where a points service corresponds to the predetermined service is given as an example. Therefore, the parts describing the points service can be read as referring to the predetermined service. The predetermined service is not limited to a points service; the predetermined service may be any other service besides a points service. The usage information acquisition unit 101 may acquire usage information for each of a plurality of predetermined services. 【0076】 Usage information may indicate whether or not a specified service was used, or it may indicate the specific usage status of the specified service. The content of the usage information depends on what the specified service is. For example, the specified service may be a payment service. If the specified service is a payment service, the usage information will indicate the user's use of the payment service. The usage information may indicate whether or not the payment service was used, the date and time of use of the payment service, the amount used, the destination, the amount charged, the amount sent, the payment method of the payer, the balance of the payment method, the payment method of the charger, the number of times the payment service was used, the period of use of the payment service, or other information. 【0077】 For example, if the specified service is a communication service, the usage information may include whether or not an application for the communication service has been made, the plan the user is currently using, the amount of data the user has used, the number of times the communication service has been used, the duration of the communication service use, or other information. If the specified service is a financial service, the usage information may include whether or not an application for the financial service has been made, the date and time of use, the amount used, the financial product the user is currently using, the number of times the financial service has been used, the duration of the financial service use, whether or not a loan exists, or other information. If the specified service is a credit card service, the usage information may include whether or not a credit card application has been made, the date and time of use, the amount used, the place of use, the payment method (e.g., installment payment, revolving payment, or bonus payment), the number of times the credit card service has been used, the duration of the credit card service use, or other information. 【0078】 The specified service may be other services such as e-commerce services, travel booking services, other payment services, e-book services, online flea market services, or administrative services. The usage information acquisition unit 101 only needs to acquire user usage information from these other services. For example, the usage information acquisition unit 101 may acquire user usage information from the systems of other services and record it in the data storage unit 100. The usage information acquisition unit 101 can acquire the usage information of other services stored in the data storage unit 100 at any time. 【0079】 In this embodiment, since point service usage information is stored in the point database DB2, the usage information acquisition unit 101 acquires point service usage information of users who are subject to the determination or confirmation of the award rate from the point database DB2. If point service usage information is stored in a database other than the point database DB2, a computer other than the settlement server 10, or an information storage medium, the usage information acquisition unit 101 can acquire point service usage information of users who are subject to the determination of the award rate from the other database, other computer, or information storage medium. 【0080】 In this embodiment, since a measurement period is set for each application period, the usage information acquisition unit 101 acquires usage information for each measurement period corresponding to each of the multiple application periods. Period data showing the relationship between the application period and the measurement period may be stored in the data storage unit 100. For example, the usage information acquisition unit 101 identifies the measurement period corresponding to the application period that is subject to determination or confirmation of the assignment rate based on the period data. The usage information acquisition unit 101 acquires usage information for the identified measurement period. 【0081】 In the example shown in Figure 3, the usage information acquisition unit 101 acquires usage information indicating usage during the measurement period, which is from January 16th to February 15th, when the grant rate for the March application period is determined or finalized. The usage information acquisition unit 101 acquires usage information indicating usage during the measurement period, which is from February 16th to March 15th, when the grant rate for the April application period is determined or finalized. The usage information acquisition unit 101 acquires usage information indicating usage during the measurement period, which is from March 16th to April 15th, when the grant rate for the May application period is determined or finalized. 【0082】 Furthermore, it is not necessary to set an application period. In this case, instead of determining or confirming the application rate each time the application period arrives, a semi-permanent application rate may be determined or confirmed. If no application period is set, no measurement period is required either. The usage information acquisition unit 101 may acquire usage information regardless of the application period and measurement period. The usage information acquisition unit 101 may acquire usage information for the entire past period, or it may acquire usage information for the most recent predetermined period (for example, the most recent year). 【0083】 [Granting Rate Determination Unit] The reward rate determination unit 102 determines, based on usage information, a reward rate for benefits granted by using a predetermined payment method, which varies depending on whether the user meets predetermined reward rate conditions and is determined at a predetermined confirmation timing. The reward rate is a rate substituted into a calculation formula for calculating the amount of benefits. For example, the reward rate may be a rate multiplied by the amount used by the predetermined payment method, a rate multiplied by the amount by which the amount used by the predetermined payment method increases by a predetermined amount, or a rate multiplied by the amount by which the amount used by the predetermined payment method decreases by a predetermined amount. 【0084】 A designated payment method is a payment method that grants benefits to the user when used. In this embodiment, the case where electronic money corresponds to the designated payment method is given as an example. Therefore, the parts describing electronic money can be read as referring to the designated payment method. The designated payment method is not limited to electronic money. The designated payment method may be any payment method other than electronic money. For example, the designated payment method may be a balance not called electronic money, a credit card, another card other than a credit card, points, a bank account, another account other than a bank account, cryptocurrency, a wallet, or another payment method. There may be multiple designated payment methods. 【0085】 A reward is an advantage or compensation given to a user for using a predetermined payment method. In this embodiment, points are given as an example of a reward. Therefore, any section describing points can be read as a reward. Rewards are not limited to points. Rewards may be other rewards besides points. For example, rewards may be cashback, electronic money top-ups, coupons, stamps, product vouchers, service vouchers, or other rewards. The award rate may be the rate substituted into the formula for calculating the cashback amount, the rate substituted into the formula for calculating the top-up amount, the rate substituted into the formula for calculating the coupon discount rate, the rate substituted into the formula for calculating the voucher amount, the rate substituted into the formula for calculating the voucher amount, the rate substituted into the formula for calculating the number of stamps, or other rates. 【0086】 The grant rate condition is a criterion for determining whether the grant rate changes or not. For example, the grant rate condition may be a condition that increases the grant rate, or a condition that decreases the grant rate. The grant rate condition may be any condition that can be determined based on usage information. The grant rate condition may also be whether the usage (usage status or usage history) indicated by the usage information is a predetermined usage (a predetermined usage status or usage history). In this embodiment, since the usage information indicates the number of uses, the grant rate condition is a condition related to the number of uses. For example, the grant rate condition is whether the number of uses is above a threshold. The grant rate condition may be any condition that corresponds to the usage information and is not limited to the example of this embodiment. For example, if the usage information indicates the amount used, the grant rate condition is whether the amount used is above a threshold. If the usage information indicates the location of use, the grant rate condition is whether the location of use is a predetermined location (a predetermined store). 【0087】 In this embodiment, since the grant rate conditions are defined in the grant rate data DT, the grant rate determination unit 102 identifies the grant rate conditions based on the grant rate data DT. The grant rate determination unit 102 determines whether the identified user satisfies the grant rate conditions based on the usage information acquired by the usage information acquisition unit 101. In the example of this embodiment, the grant rate determination unit 102 determines whether the user satisfies the grant rate conditions by determining whether the number of uses indicated by the usage information is equal to or greater than a threshold (for example, 2 times). If multiple grant rate conditions are defined in the grant rate data DT, the grant rate determination unit 102 can identify the multiple grant rate conditions based on the grant rate data DT and determine whether each of the multiple grant rate conditions is satisfied based on the usage information acquired by the usage information acquisition unit 101. 【0088】 In this embodiment, the award rate determination unit 102 determines the award rate for electronic money usage based on usage information, and determines the final award rate by adding the determined award rate for electronic money usage and the award rate for payment app usage. The award rate determination unit 102 may store the final award rate in the point database DB2. The award rate determination unit 102 may also determine only the award rate for electronic money usage without specifically calculating the final award rate. For example, the display control unit 103, described later, may display the award rate for electronic money usage and the award rate for payment app usage separately on the award rate screen SC2. 【0089】 For example, if an award rate is defined in the award rate data DT, the award rate determination unit 102 determines the award rate based on the award rate data DT, according to the result of determining whether the user meets the award rate conditions. The award rate determination unit 102 determines the award rate when the user meets the award rate conditions, based on the award rate data DT. The award rate determination unit 102 determines the award rate when the award rate conditions are not met, based on the award rate data DT. The award rate determination unit 102 updates the user's award rate in the point database DB2 to the award rate according to the determination result of the award rate determination unit 102. The award rate determination unit 102 may store the award rate in the point database DB2 along with information that can identify the period to which the award rate applies. 【0090】 In this embodiment, the award rate determination unit 102 determines at a predetermined timing whether the user meets the award rate conditions. If the award rate determination unit 102 determines that the user does not meet the award rate conditions, it determines a first award rate. If the award rate determination unit 102 determines that the user meets the award rate conditions, it determines a second award rate that is higher than the first award rate. The first and second award rates are defined in the award rate data DT. The first and second award rates may be arbitrary values. For example, the first award rate may be 0%. The difference between the first and second award rates may also be arbitrary. 【0091】 The determination timing is the timing at which the grant rate determination unit 102 determines whether or not the user meets the grant rate conditions. In this embodiment, an example is given where the determination timing is different from the confirmation timing. For example, the determination timing may be the timing at which the grant rate screen SC2 is displayed, the timing at which the latest usage information is acquired (the timing at which user usage is reflected as usage information), the timing at which the payment application is launched, the timing at which the user performs a predetermined operation in the payment application, or any other timing. The determination timing may also be the same as the confirmation timing. In this embodiment, an example is given where the determination timing is earlier than the confirmation timing. 【0092】 For example, if the timing at which the reward rate screen SC2 is displayed corresponds to the determination timing, the reward rate determination unit 102 determines whether the user meets the reward rate conditions based on the usage information acquired when the determination timing arrives. The reward rate determination unit 102 determines whether the user meets the reward rate conditions by determining whether the number of times the point card has been used, as acquired from the usage information, is equal to or greater than a threshold. 【0093】 In this embodiment, since the application period occurs repeatedly, the grant rate determination unit 102 determines the grant rate to be determined at the confirmation timing corresponding to each of the multiple application periods. The grant rate determination unit 102 determines the grant rate to be determined at the confirmation timing corresponding to each application period. If the determination timing is before the confirmation timing, the grant rate determination unit 102 determines whether the user meets the grant rate conditions based on the usage information at the determination timing before the confirmation timing for a certain application period occurs. The grant rate determination unit 102 determines the application rate for that application period based on the determination result for that application period. 【0094】 In this embodiment, since there is a measurement period for each application period, the award rate determination unit 102 determines the award rate for each application period based on the usage information in the measurement period corresponding to each of the multiple application periods. The award rate determination unit 102 determines the award rate for each application period based on the usage information in the measurement period corresponding to that application period. For each application period, the award rate determination unit 102 determines whether the user meets the award rate conditions by determining whether the number of times the point card is used, obtained from the usage information in the measurement period corresponding to that application period, is equal to or greater than a threshold, and determines the award rate for that application period based on the determination result. 【0095】 For example, the grant rate determination unit 102 may determine the grant rate for the current application period by determining whether the user meets the grant rate conditions based on usage information in the measurement period corresponding to the current application period. The grant rate determination unit 102 may determine the grant rate for future application periods by determining whether the user meets the grant rate conditions based on usage information in the measurement period corresponding to future application periods. The grant rate determination unit 102 may determine the grant rate for past application periods by determining whether the user meets the grant rate conditions based on usage information in the measurement period corresponding to past application periods. The multiple application periods that the grant rate determination unit 102 is responsible for determining may include any of the current application period, future application periods, and past application periods. 【0096】 The point accrual rate determination unit 102 may unconditionally count the usage as one when the point code C12 or a physical point card is read, or it may determine whether or not to count the usage under predetermined conditions. For example, the point accrual rate determination unit 102 may count the usage on the condition that the usage amount is above a predetermined amount, on the condition that the usage is at a predetermined store, or on the condition that a predetermined product or service is purchased. The same applies when the usage information is other information besides the number of uses. 【0097】 In this embodiment, the grant rate determination unit 102 determines the grant rate at a predetermined confirmation timing based on usage information. For example, the grant rate determination unit 102 determines whether the confirmation timing has arrived by determining whether the current time is a predetermined date and time. If the grant rate determination unit 102 determines that the confirmation timing has not arrived, it does not determine the grant rate, and if it determines that the confirmation timing has arrived, it determines the grant rate. The grant rate determination unit 102 determines the grant rate for the application period in which the confirmation timing has not arrived, and does not need to confirm that grant rate. 【0098】 For example, the award rate determination unit 102 determines the award rate by storing the award rate in the point database DB2. If a status is stored in the point database DB2, the award rate determination unit 102 may store the award rate in the point database DB2 along with the status indicating that the award rate has been determined. When the settlement server 10 needs to calculate points, it refers to the award rate stored in the point database DB2. The award rate determination unit 102 may determine whether the user meets the award rate conditions at a determination timing that is later than the determination timing. If the award rate determination unit 102 determines that the user does not meet the award rate conditions, it determines the first award rate as the award rate, and if it determines that the user meets the award rate conditions, it determines the second award rate as the award rate. 【0099】 For example, usage information may include the number of times a point card has been used or the amount spent. Usage information may also include information about actions that cause the user to no longer meet the reward rate conditions (for example, cancellation of an order, purchase, or reservation, or a decrease in the transaction amount due to a change in products, etc.). The reward rate determination unit 102 may determine whether the user meets the reward rate conditions based on this usage information when the determination timing arrives during the measurement period. Other information related to usage information may include usage information that has been determined to be fraudulent, information about fraudulent activities by the user, or information about restrictions on the user's use or cancellation of their account. 【0100】 For example, the reward rate determination unit 102 determines whether the user meets the reward rate conditions based on usage information. Subsequently, the reward rate determination unit 102 may determine whether the user meets the reward rate conditions based on other information. Specifically, as shown in (Example 1) to (Example 3) below, the reward rate determination unit 102 may change the reward rate during the measurement period based on the number of times the user uses the point card. (Example 1) Used once → Not achieved 2 times → Displayed reward rate of 1.0% (undetermined) (Example 2) 1 use → 2 uses achieved → Displayed reward rate of 1.5% (unconfirmed) (Example 3) Based on other information, a cancellation of point card usage is detected → 2 times not achieved → 1.0% (unconfirmed) is displayed. 【0101】 For example, if the determination timing for the buffer period up to a certain application period arrives after the measurement period corresponding to that application period has ended, the assignment rate determination unit 102 may determine the assignment rate by executing a batch file. In this case, the assignment rate determination unit 102 may use the same data as the processing in the measurement period described above and perform the same processing. The assignment rate determination unit 102 may also use different data than the processing in the measurement period described above and perform different processing. For example, a determination based on other information may not be performed in the measurement period, but only at the determination timing in the buffer period. As a specific example, the following processing (Example 4) may be performed. (Example 4) 1 use → 2 uses achieved → Displayed reward rate of 1.5% (unconfirmed) 【0102】 For example, in (Example 4), although the use of the point card occurs during the measurement period, the usage information may be linked during the buffer period after the measurement period has ended, and this may be detected by the award rate determination unit 102. The reflection of point card data used during the measurement period may also be allowed during the buffer period. For this reason, the award rate may change before the batch file is executed. Ultimately, based on (Example 1) to (Example 4), the user has achieved two point card usages, so it may display "Award rate of 1.5% (confirmed)". 【0103】 The award rate conditions may also be conditions that result in a decrease in the award rate. In this case, the award rate determination unit 102 may determine a first award rate as the user's award rate if it determines that the user meets the award rate conditions. The award rate determination unit 102 may determine a second award rate as the user's award rate if it determines that the user does not meet the award rate conditions. The award rate determination unit 102 may determine an award rate that fluctuates in three or more stages. The award rate determination unit 102 may determine whether the user meets each of the multiple award rate conditions and determine the award rate corresponding to the award rate conditions that the user meets as the user's award rate. 【0104】 Furthermore, the reward rate determination unit 102 may determine a reward rate that is not particularly related to the payment method, rather than a reward rate for electronic money usage. For example, if a common reward rate is used in the point calculation regardless of the payment method used, the reward rate determination unit 102 may calculate a common reward rate based on the usage information. If there is no specific reward rate for electronic money usage, and only a reward rate for payment app usage exists, the reward rate determination unit 102 may determine the reward rate for payment app usage based on the usage information. If there is a reward rate for usage of other payment methods such as credit cards, the reward rate determination unit 102 may determine the reward rate for usage of other payment methods based on the usage information. 【0105】 [Display Control Unit] The display control unit 103 causes the user terminal 20 to display various screens. In this embodiment, since the display control unit 103 is implemented by the payment server 10, the display control unit 103 causes the user terminal 20 to display the screen by transmitting display data for the screen to be displayed to the user terminal 20. The display data is data that causes the user terminal 20 to display some screen. The display data may be data for the entire screen or data for a part of the screen. The display data may be in any format. For example, the display data may be data in a markup language such as HTML, or image data. 【0106】 In this embodiment, the display control unit 103 causes the user terminal 20 to display an award rate screen SC2 showing the award rate and a status indicating whether or not the award rate has been determined. The award rate is represented by numbers, letters, other symbols, images, or a combination thereof. The status is information indicating whether or not the award rate has been determined. The status may also be represented by numbers, letters, other symbols, images, or a combination thereof. The status may also indicate the timing of the determination of the award rate. The award rate and the status may be displayed separately on the award rate screen SC2, or they may be combined into one on the award rate screen SC2. 【0107】 For example, the display control unit 103 obtains the award rate determined by the award rate determination unit 102. The award rate determined by the award rate determination unit 102 may be stored in the payment database DB1, the points database DB2, or another database. In this case, the display control unit 103 obtains the user's award rate from one of these databases. The display control unit 103 obtains the status of the award rate. The status may be associated with the award rate and stored in these databases. In this case, the display control unit 103 only needs to obtain the status from these databases. 【0108】 The display control unit 103 may also obtain the status based on the current date and time. For example, the display control unit 103 may obtain the status based on whether the current time is within the application period, regardless of the confirmation timing. The display control unit 103 may also obtain a status indicating that the grant rate for the application period including the current time has been confirmed. In the example in Figures 3 and 4, since the current time is one of the days between March 1st and 15th, the display control unit 103 displays the grant rate screen SC2 on the user terminal 20 so that the status for the application period of March to which the current time belongs is confirmed. The display control unit 103 displays the grant rate for March and the status indicating that the grant rate has been confirmed in the heading of the tab T20A corresponding to the application period of March. 【0109】 For example, if the current time is before the application period, the display control unit 103 may obtain a status indicating that the grant rate has not been determined. In the example in Figures 3 and 4, since the current time is one of the days between March 1st and 15th, the display control unit 103 displays the grant rate screen SC2 on the user terminal 20 so that the status for the application periods of April and May, which are later than the current month, is undetermined. The display control unit 103 displays the grant rate for April and a status indicating that the grant rate has not been determined in the heading of tab T20B corresponding to the application period of April. The display control unit 103 displays the grant rate for May and a status indicating that the grant rate has not been determined in the heading of tab T20C corresponding to the application period of May. 【0110】 In this embodiment, the display control unit 103 displays a grant rate screen SC2 on the user terminal 20, showing the first grant rate and the status, when it is determined that the user does not meet the grant rate conditions. In the upper right, lower left, and lower right examples of Figure 4, the first grant rate is 1.0%, which is the sum of the grant rate of 0.5% for payment app usage and the grant rate of 0.5% for electronic money usage. For example, the display control unit 103 displays a grant rate screen SC2 on the user terminal 20, showing the first grant rate of 1.0% and the status of whether or not the first grant rate for each month has been determined. 【0111】 Furthermore, the first award rate is not limited to 1.0%. The first award rate only needs to be lower than the second award rate. The first award rate can be any rate. For example, the first award rate may be less than 1.0% or higher than 1.0%. Also, the award rate for payments made using the payment app may be the only award rate that corresponds to the first award rate. In this case, the display control unit 103 may display an award rate screen SC2 on the user terminal 20 that shows 0.5%, which is the award rate for payments made using the payment app, as the first award rate. In this case as well, the first award rate is not limited to 0.5%. The first award rate may be less than 0.5% or higher than 0.5%. 【0112】 In this embodiment, the display control unit 103 displays a grant rate screen SC2 on the user terminal 20, showing the second grant rate and status, when it is determined that the user meets the grant rate conditions. In the upper left, upper right, lower left, and lower right examples of Figure 5, the second grant rate is 1.5%, which is the sum of the grant rate for payment app usage (0.5%) and the grant rate for electronic money usage (1.0%). For example, the display control unit 103 displays a grant rate screen SC2 on the user terminal 20, showing the second grant rate of 1.5%, the status of whether or not the second grant rate for March and April has been determined. 【0113】 Furthermore, the second reward rate is not limited to 1.5%. The second reward rate only needs to be higher than the first reward rate. The second reward rate can be any rate. For example, the second reward rate may be less than 1.5% or higher than 1.5%. Also, the reward rate for payments made using the payment app may be the only reward rate that corresponds to the second reward rate. In this case, the display control unit 103 may display a reward rate screen SC2 on the user terminal 20 that shows 1.0% as the reward rate for payments made using the payment app as the second reward rate. In this case as well, the second reward rate is not limited to 1.0%. The second reward rate may be less than 1.0% or higher than 1.0%. 【0114】 In this embodiment, the display control unit 103 displays an award rate screen SC2 on the user terminal 20 that displays the status differently depending on whether the award rate has been determined or not. For example, when the award rate has been determined, the display control unit 103 displays an award rate screen SC2 on the user terminal 20 that shows the status of the award rate with a first display (in the example of Figures 4 and 5, the "determined" icon) and when the award rate has not been determined, it shows the status of the award rate with a second display different from the first display (in the example of Figures 4 and 5, the "undetermined" icon). 【0115】 A different status display means that the characters, numbers, other symbols, images, or combinations thereof used to indicate the status are different. For example, a difference in the specific content represented by the characters, numbers, other symbols, images, or combinations thereof constitutes a different status display. Even if the specific content represented by the characters, numbers, other symbols, images, or combinations thereof is the same, a difference in the color, size, font, effect, orientation, or combination of these may constitute a different status display. 【0116】 In this embodiment, the display control unit 103 displays a status screen SC2 on the user terminal 20 that is associated with the award rate, with different displays depending on whether the award rate is determined or not. A status being associated with an award rate means that the status is displayed near the award rate, the status is displayed in the same area as the award rate (for example, in the heading of tab T20), the status is displayed in a way that points to the award rate, or the award rate is displayed in a way that points to the status. 【0117】 In this embodiment, the display control unit 103 causes the user terminal 20 to display an award rate screen SC2 that can display the award rate and status for each of a plurality of application periods. In the example in Figures 4 and 5, there are three application periods displayed on the award rate screen SC2, but the number of application periods displayed on the award rate screen SC2 is not limited to three. There may be one, two, or four or more application periods displayed on the award rate screen SC2. 【0118】 For example, the display control unit 103 may display a grant rate screen SC2 on the user terminal 20, which shows the grant rate and status for the current application period and for future application periods, respectively. In the examples in Figures 4 and 5, the current application period is March. The future application periods are April and May. The future application periods shown on the grant rate screen SC2 are not limited to two. For example, the future application periods shown on the grant rate screen SC2 may be one, three, or more. 【0119】 The display control unit 103 may also display a grant rate screen SC2 on the user terminal 20 that shows the grant rate and status for the current application period and for past application periods. The display control unit 103 may also display a grant rate screen SC2 on the user terminal 20 that shows the grant rate and status for past application periods and for past application periods. The display control unit 103 may also display a grant rate screen SC2 on the user terminal 20 that shows the grant rate and status for the current application period and for past application periods. 【0120】 Furthermore, the display control unit 103 may display a grant rate screen SC2 on the user terminal 20 that shows only the grant rate and status for one application period, rather than multiple application periods. For example, the display control unit 103 may display a grant rate screen SC2 on the user terminal 20 that shows only the grant rate and status for the current application period, a future application period, or a past application period. The display control unit 103 may also display a grant rate screen SC2 on the user terminal 20 that can display the grant rate and status for an application period selected by the user from among multiple application periods. 【0121】 For example, the display control unit 103 may display an award rate screen SC2 on the user terminal 20 that simultaneously shows the award rate and status for each of the multiple application periods, or the display control unit 103 may display an award rate screen SC2 on the user terminal 20 that allows the user to switch between and display the award rates and status for each of the multiple application periods. In the examples of Figures 4 and 5, the detailed display in tab T20 is only for one application period, but the award rates and status for each of the multiple application periods are displayed as headings for tab T20. Therefore, the display control unit 103 can simultaneously display the award rates and status for each of the multiple application periods in the tab T20 corresponding to each of the multiple application periods. 【0122】 In this embodiment, the display control unit 103 causes the user terminal 20 to display an award rate screen SC2 that can display the award rate and status for the current application period, and the award rate and status for the future application period corresponding to the current measurement period. In the example in Figures 4 and 5, the current application period is March. The current measurement period is April. The future application period corresponding to the current measurement period is also April. For example, the display control unit 103 causes the user terminal 20 to display an award rate screen SC2 that shows the award rate for March determined by the award rate determination unit 102, a status indicating that the award rate for March has been determined, the award rate for April determined by the award rate determination unit 102, and a status indicating that the award rate for April has not been determined. 【0123】 In this embodiment, the display control unit 103 causes the user terminal 20 to display an award rate screen SC2 indicating that the status for the current application period is confirmed and the status for future application periods is not yet confirmed. The status for future application periods will remain unconfirmed even if the user is determined to meet the award rate conditions. In the example in Figures 4 and 5, the current application period is March. The future application periods are April and May. If the award rates for April and May have not yet been confirmed, the display control unit 103 causes the user terminal 20 to display an award rate screen SC2 indicating that the award rates for April and May have not yet been confirmed. Even if the award rate for April has been determined at the determination timing, the display control unit 103 causes the user terminal 20 to display an award rate screen SC2 indicating that the award rate for April has not yet been confirmed. Even if the confirmation timing for April arrives and the award rate for April has been confirmed, if it is not yet April, the display control unit 103 causes the user terminal 20 to display an award rate screen SC2 indicating that the award rate for April has not yet been confirmed. 【0124】 In this embodiment, the display control unit 103 displays a grant rate screen SC2 on the user terminal 20, showing the difference until the user satisfies the grant rate conditions, for the application period corresponding to the current measurement period among a plurality of application periods in which the user does not satisfy the grant rate conditions. The difference is the difference between the content indicated by the usage information and the content required to satisfy the grant rate conditions. The difference can also be described as the remaining content until the grant rate conditions are satisfied. The display control unit 103 calculates the difference based on the usage information and the grant rate conditions. For example, the display control unit 103 calculates the difference between the number of times the point service is used indicated by the usage information and the threshold indicated by the grant rate conditions. 【0125】 In the example in the upper right of Figure 4, the display control unit 103 displays a reward rate screen SC2 on the user terminal 20 for the application period in April, which includes a callout that says "2 more times to achieve" as the difference until the user meets the reward rate condition (for example, using the point card two or more times). The display control unit 103 can display the difference in any way. The method of displaying the difference is not limited to a callout as shown in Figure 4. For example, the display control unit 103 may display a reward rate screen SC2 on the user terminal 20 that shows the difference using characters, numbers, other symbols, images (for example, a gauge of a predetermined shape), or a combination thereof. 【0126】 The display control unit 103 may calculate the difference using a calculation method appropriate to the usage information and the award rate conditions. For example, if the usage information and award rate conditions are the frequency of use of the point service, the display control unit 103 calculates the difference between the frequency of use of the point service indicated by the usage information and the threshold indicated by the award rate conditions. If the usage information and award rate conditions are the amount of money spent on the point service, the display control unit 103 calculates the difference between the amount of money spent on the point service indicated by the usage information and the threshold indicated by the award rate conditions. If the usage information and award rate conditions indicate other content, the display control unit 103 may calculate the difference using a calculation method appropriate to that other content. 【0127】 In this embodiment, the display control unit 103 includes tabs T20 corresponding to each of a plurality of application periods, and displays the award rate screen SC2 on the user terminal 20, with the tab T20 corresponding to the application period corresponding to the current measurement period selected by default. The tab T20 corresponding to the application period is the tab T20 that displays the award rate and status for the application period. There is a one-to-one correspondence between the application period to be displayed on the award rate screen SC2 and the tab T20 included in the award rate screen SC2. The award rate screen SC2 includes a tab T20 for each application period. 【0128】 Figure 10 shows an example of the default tab T20 selection. The state in the upper left of Figure 10 is the same as the state in the upper left of Figure 4. For example, if the current date is March 1st to 15th, the display control unit 103 will display the same award rate screen SC2 as in the upper right of Figure 4 on the user terminal 20, as shown in the upper right of Figure 10. If the user selects tab T20C in the state shown in the upper right of Figure 10, the award rate screen SC2 will change to the state in the lower right of Figure 4. 【0129】 For example, if the current date is March 16th to 31st, the display control unit 103 will display the reward rate screen SC2 on the user terminal 20 with tab T20C for May, which is the applicable period corresponding to the measurement period including the current date, selected by default, as shown in the lower right of Figure 10. If the number of times the point card has been used during the measurement period corresponding to the applicable period for April is less than two, and the user selects tab T20B in the state shown in the lower right of Figure 10, the reward rate screen SC2 will change from the state shown in the upper right of Figure 10 to a state where the "2 more uses until achieved" speech bubble is removed. 【0130】 In the example in the lower right of Figure 10, let's assume that the timing for determining the application period for April was March 27th. Furthermore, let's assume that the user displays the grant rate screen SC2 after the determination timing in March (for example, on March 28th). In this case, the status of tab T20B may indicate that the grant rate has been determined, but in this embodiment, it will indicate that the grant rate has not been determined. That is, although the grant rate for the application period for April has actually been determined, since it is not yet April, which is the application period, the status of tab T20B may indicate that the grant rate has not been determined. When April arrives, the application period for April moves to tab 20A. Tab 20B shows the application period for May. Tab 20C shows the application period for June. Similarly thereafter, each time a new month arrives, the month shown in tabs 20A to 20C moves one position to the left. 【0131】 For example, the display of the grant rate screen SC2 switches based on the user's actions on tab T20 corresponding to each of multiple application periods. When the user performs an operation to select tab T20, the user terminal 20 notifies the payment server 10 of the operation performed by the user. The display control unit 103 may execute the process of switching tab T20 based on the notification. The display control unit 103 may send display data of the grant rate screen SC2 with an embedded script for switching tab T20 to the user terminal 20. The user terminal 20 may execute the script to switch tab T20. 【0132】 In this embodiment, the display control unit 103 displays a grant rate screen SC2 on the user terminal 20 that shows the grant rate and status, as well as information regarding the grant rate conditions, for the application period corresponding to the current measurement period among a plurality of application periods. In the example in Figure 4, the application period corresponding to the current measurement period is April. For example, as shown in the upper right of Figure 4, the display control unit 103 displays a grant rate screen SC2 on the user terminal 20 that shows information regarding the grant rate conditions, such as "2 more times to achieve". For example, the information regarding the grant rate conditions may be information indicating the grant rate conditions (e.g., a link or text), or it may be information about the difference until the user satisfies the grant rate conditions. 【0133】 In this embodiment, the current application period overlaps with the measurement period corresponding to at least the next application period (e.g., the following month) after the current application period (e.g., the current month when the grant rate screen SC2 is displayed). These application periods and measurement periods may overlap completely or partially. For example, the current application period may overlap with the measurement period corresponding to the next application period after the current application period, and with the measurement period corresponding to the two application periods after the current application period (e.g., the month after next). In the examples in Figures 4 and 5, the current application period is March. In the example in Figure 3, the next application period after the current application period is April. The measurement period corresponding to April includes March. The two application periods after the current application period is May. The measurement period corresponding to May includes April. 【0134】 For example, multiple application periods include the current application period and the next application period. Multiple application periods may also include the current application period, the next application period, and the period two applications later. In the example of Figures 4 and 5, the multiple application periods are March, which is the current application period; April, which is the next application period; and May, which is the period two applications later. The display control unit 103 causes the user terminal 20 to display an award rate screen SC2 that can display the award rate and status for each of the current application period, the next application period, and the period two applications later. The display control unit 103 may also cause the user terminal 20 to display an award rate screen SC2 that can display the award rate and status for each of the current application period, the next application period, and the period two applications later. The display control unit 103 causes the user terminal 20 to display the grant rate screen SC2 on tabs T20A to T20C, which shows the grant rate and status for each of the following application periods: March (the current application period), April (the next application period), and May (the period after that). 【0135】 If the application period is a week rather than a month, the current application period is this week as of the time the SC2 grant rate screen is displayed. The next application period is the following week. The period two weeks after that is the week after that. If the application period is a period other than a month or a week, the current application period, the next application period, and the period two weeks after that can each be a period of a length corresponding to the other period. 【0136】 In this embodiment, the display control unit 103 causes the user terminal 20 to display an award rate screen SC2, which includes tabs T20 corresponding to each of the multiple application periods, with the award rate and status placed as headings. When the user selects any of the tabs T20 corresponding to each of the multiple application periods, details regarding the application period corresponding to that tab are displayed on the award rate screen SC2. 【0137】 In the examples shown in Figures 4 and 5, when the user selects any of the tabs T20, the display control unit 103 displays details such as the achievement status of the award rate conditions for the application period corresponding to the selected tab T20 on the selected tab T20. The display control unit 103 may also send display data of the award rate screen SC2, which has a script for switching tabs T20 embedded in it, to the user terminal 20. The user terminal 20 may switch tabs T20 by executing the script. 【0138】 The display control unit 103 may also display a grant rate screen SC2 on the user terminal 20 that does not include tab T20. For example, the display control unit 103 may display a grant rate screen SC2 on the user terminal 20 that shows the grant rate and status for a certain application period. The grant rate screen SC2 may include user interface parts for the user to switch application periods (for example, a "<" symbol to indicate returning to the previous application period, a ">" symbol to indicate moving to the next application period, or icons thereof). The display control unit 103 may also display a grant rate screen SC2 on the user terminal 20 that allows the application period to be changed according to the selection of such parts. 【0139】 Furthermore, if the conditions for a decrease in the award rate correspond to the award rate conditions, the display control unit 103 may display an award rate screen SC2 showing the first award rate and status on the user terminal 20 if it is determined that the user meets the award rate conditions. The display control unit 103 may also display an award rate screen SC2 showing the second award rate and status on the user terminal 20 if it is determined that the user does not meet the award rate conditions. The display control unit 103 may also display an award rate screen SC2 on the user terminal 20 showing an award rate that fluctuates in three or more stages, and the status of that award rate. 【0140】 Furthermore, the display control unit 103 may not differentiate the status display depending on whether the award rate is determined or not, but may display the status when the award rate is determined and not display the status when the award rate is not determined. Conversely, the display control unit 103 may display the status when the award rate is not determined and not display the status when the award rate is determined. In such an embodiment, the user can determine whether the award rate is determined or not by the presence or absence of a status on the award rate screen SC2. 【0141】 [3-2. Functions implemented on the user terminal] For example, the user terminal 20 includes a data storage unit 200, an operation reception unit 201, and a display control unit 202. The data storage unit 200 is implemented by a storage unit 22. The operation reception unit 201 and the display control unit 202 are implemented by a control unit 21. 【0142】 [Data Storage Unit] The data storage unit 200 stores data necessary for the user to use at least one of the payment service and the points service. For example, the data storage unit 200 stores the payment app. If the user uses the payment service from another app or browser instead of the payment app, the data storage unit 200 stores the other app or browser. The data storage unit 200 may also store a payment code ID, a points code ID, or other information. 【0143】 [Operation Reception Section] The operation reception unit 201 receives various user operations. For example, the operation reception unit 201 receives operations on the payment application. The operation reception unit 201 transmits data indicating the user's operations to the payment server 10. 【0144】 [Display Control Unit] The display control unit 202 displays various screens on the display unit 25. For example, the display control unit 202 displays the top screen SC1 and the award rate screen SC2 on the display unit 25. The display control unit 202 communicates with the payment server 10 to receive display data for these screens and displays these screens on the display unit 25 based on the display data. The display data is the data necessary for displaying the screen. The display data may be data for the entire screen or data for a part of the screen. For example, the display data may be data in a markup language such as HTML, image data, text data, or other data. 【0145】 [4. Processing performed by the display control system] Figure 11 shows an example of the processing performed by the display control system 1. The processing in Figure 11 is performed by the control units 11 and 21 executing programs stored in the storage units 12 and 22, respectively. Each step in Figure 11 is an example of a display control method. 【0146】 As shown in Figure 11, when a user operates the user terminal 20 to launch the payment application, the payment server 10 performs a login process with the user terminal 20 to allow the user to log in to the payment service (S1). In S1, the user terminal 20 sends the login account and password entered by the user to the payment server 10. The payment server 10 performs the login process by referring to the payment database DB1 and verifying the validity of the login account and password. If the login process is successful, the payment server 10 becomes able to identify the user ID associated with the login account. 【0147】 If the login process in S1 is successful, the payment server 10 executes a process to display the top screen SC1 on the user terminal 20 (S2). In S2, the payment server 10 issues a payment code ID and stores it in the payment database DB1. The payment server 10 generates a payment code C10 that indicates the payment code ID and displays the top screen SC1 on the user terminal 20. 【0148】 When the top screen SC1 is displayed in S2, various processes can be executed. For example, when a user has a merchant terminal, which is a terminal of a payment service merchant, read the payment code C10, the payment server 10 executes the payment process with the merchant terminal. The payment process may be the same as known processes. The user can perform various operations from the top screen SC1. The following describes the process when the user selects the point card tab T11 and the process when the user selects icon I13. 【0149】 The user terminal 20 identifies the user's operation on the operation unit 24 (S3). In S3, when the user selects the point card tab T11 (S3: Point Card), the payment server 10 performs a process with the user terminal 20 to display the point code C12 on the top screen SC1 (S4). In S4, the payment server 10 issues a point code ID and stores it in the point database DB2. The payment server 10 generates a point code C12 that indicates the point code ID and displays the top screen SC1 on the user terminal 20. 【0150】 Note that the processing of S4 may be performed by the point server, which is the point service server, instead of the payment server 10. For example, when a user selects the point card tab T11, the user terminal 20 starts communication with the point server. The point server issues a point code ID and displays the point code C12 on the top screen SC1. The point server may also send the point code ID to the payment server 10. 【0151】 When the point code C12 is displayed on the top screen SC1, the merchant terminal, which is the terminal of the point service participating store, reads the point code C12. The merchant terminal obtains the point code ID from the point code C12 and sends it to the payment server 10. When the payment server 10 obtains the point code ID from the merchant terminal (S5), it updates the user usage information to indicate that the user corresponding to the point code ID (the user whose user ID is associated with the point code ID) has used the point service (S6). 【0152】 Note that the processes in S5 and S6 may be executed by the points server instead of the payment server 10. The merchant terminal may send the points code ID to the points server instead of the payment server 10. When the points server receives the points code ID from the merchant terminal, it may update the usage information stored in its own database. The points server may send the updated usage information to the payment server 10. Thereafter, when the payment code C10 is read by the merchant terminal and payment is executed, points are awarded to the user. 【0153】 The payment server 10 determines whether the timing for determining the reward rate has arrived (S7). In Figure 11, the process in S7 is shown as the process after the user selects the point card tab T11, but the process in S7 may be executed regardless of whether the user has selected the point card tab T11 or not. For example, the process in S7 may be executed when a predetermined date and time each month arrives (for example, a predetermined time on the 27th of each month). If it is determined in S7 that the timing for determining the reward rate has arrived (S7:N), this process terminates. 【0154】 In S7, if it is determined that the timing for determining the grant rate has arrived (S7:Y), the settlement server 10 executes a process to determine and determine the grant rate based on the usage information (S8). In S8, the settlement server 10 determines the grant rate based on the usage information for the measurement period corresponding to the applicable period to be determined, and the grant rate data DT. The settlement server 10 determines the grant rate by storing the determined grant rate in the point database DB2 in association with the user ID of the logged-in user. 【0155】 In S3, when the user selects icon I13 which indicates the display of the grant rate screen SC2 (S3: Grant Rate Screen), the user terminal 20 sends a request to the payment server 10 to display the grant rate screen SC2 (S9). When the payment server 10 receives the request to display the grant rate screen SC2 (S10), it obtains the usage information of the logged-in user based on the point database DB2 (S11). In S11, the payment server 10 may obtain usage information for the entire past period, or it may obtain usage information showing usage for each of the multiple applicable periods (March to May in the examples of Figures 4 and 5) that are subject to display on the grant rate screen SC2. 【0156】 The payment server 10 determines the grant rate for each of the multiple application periods based on the usage information obtained in S11 and the grant rate data DT (S12). In S12, for each application period, the payment server 10 determines whether the user meets the grant rate conditions based on the usage information in the measurement period corresponding to that application period, and determines the grant rate based on the result of that determination. The payment server 10 may also perform the process in S12 for application periods that are not yet determined. For application periods that have already been determined, the payment server 10 may obtain the determined grant rate from the point database DB2 without determining the grant rate in S12. 【0157】 The payment server 10 executes a process to display the award rate screen SC2, which shows the award rate determined in S12 and the status of whether or not the award rate has been confirmed, in communication with the user terminal 20 (S13), and then terminates this process. In S13, the payment server 10 generates the display data for the award rate screen SC2 so that the tab T20 corresponding to the applicable period, which includes the current time, is selected by default. The format of the display data for the award rate screen SC2 may be such that the "Confirmed" icon is placed on tab T20A and the "Not Confirmed" icons are placed on tabs T20B and T20C. The payment server 10 may also place information about the award rate and a callout corresponding to the number of times the point card has been used as indicated by the usage information (e.g., "2 more times to achieve" in the example in Figure 4, or "Achieved! Presented 2 times" in the example in Figure 5) in the format. 【0158】 [5. Summary of Embodiments] The display control system 1 of this embodiment acquires usage information. Based on the usage information, the display control system 1 determines the award rate. The display control system 1 causes the user terminal 20 to display an award rate screen SC2 that shows the award rate and the status regarding whether the award rate has been determined or not. As a result, the user can check the award rate for each application period and whether the award rate has been determined or not on the award rate screen SC2, so the display control system 1 can improve user convenience. For example, when the award rate fluctuates, the user has a need to easily understand the award rate according to whether or not they meet the award rate conditions and the status of whether or not the award rate has been determined or not. In this respect, the display control system 1 can satisfy this need with the award rate screen SC2. 【0159】 Furthermore, the display control system 1 determines at a predetermined timing whether the user meets the grant rate conditions. If the display control system 1 determines that the user does not meet the grant rate conditions, it determines a first grant rate. If the display control system 1 determines that the user meets the grant rate conditions, it determines a second grant rate. If the display control system 1 determines that the user does not meet the grant rate conditions, it displays the first grant rate and the grant rate screen SC2 showing the status on the user terminal 20. If the display control system 1 determines that the user meets the grant rate conditions, it displays the second grant rate and the grant rate screen SC2 showing the status on the user terminal 20. As a result, the user can check which of the first and second grant rates has been determined for them on the grant rate screen SC2, thus improving user convenience. For example, if the determination timing is different from the confirmation timing, the display control system 1 can make the user aware of either the first or second grant rate as a grant rate that has not yet been confirmed but may be confirmed in the future. 【0160】 Furthermore, if the judgment timing is before the confirmation timing, the display control system 1 determines whether the user meets the grant rate conditions at the confirmation timing, which is after the judgment timing. If the display control system 1 determines that the user does not meet the grant rate conditions, it confirms the first grant rate as the grant rate. If the display control system 1 determines that the user meets the grant rate conditions, it confirms the second grant rate as the grant rate. In this way, the display control system 1 can make the user aware of the first or second grant rate as a grant rate that may be confirmed in the future, even before the confirmation timing arrives. For example, by determining whether the user meets the grant rate conditions and changing the grant rate before the confirmation timing, the user can see that their actions are reflected in the grant rate, thus increasing their motivation to meet the grant rate conditions. The display control system 1 can prevent payment cancellations or fraudulent payments by determining the grant rate conditions again at the confirmation timing even after the judgment has been performed at the judgment timing. 【0161】 Furthermore, the display control system 1 displays a status on the user terminal 20 that is associated with the award rate, SC2, which has different displays depending on whether the award rate has been determined or not. This makes it easier for the user to understand whether the award rate has been determined or not based on the difference in the status displayed on the award rate screen SC2. 【0162】 Furthermore, the display control system 1 determines the grant rate to be finalized at the confirmation timing corresponding to each of the multiple application periods. The display control system 1 displays a grant rate screen SC2 on the user terminal 20, which can display the grant rate and status for each of the multiple application periods. As a result, when the application periods occur repeatedly, the user can understand the grant rate and status for each application period, thus improving user convenience for the display control system 1. 【0163】 Furthermore, the display control system 1 acquires usage information for each measurement period corresponding to each of the multiple application periods. Based on the usage information for each measurement period corresponding to each of the multiple application periods, the display control system 1 determines the grant rate for that application period. This makes it easier for the user to understand each phase, such as the measurement period, the confirmation timing, and the application period, thus improving user convenience. 【0164】 Furthermore, the display control system 1 displays an award rate screen SC2 on the user terminal 20, which can display the award rate and status for the current application period, and the award rate and status for future application periods corresponding to the current measurement period. This allows the user to understand not only the award rate and status for the current application period, but also for future application periods, thus improving user convenience. For example, the user can understand what they should do in the current measurement period in order to apply a higher award rate in future application periods. 【0165】 Furthermore, the display control system 1 displays a grant rate screen SC2 on the user terminal 20, which shows the status as confirmed for the current application period and as unconfirmed for future application periods. The status for future application periods will remain unconfirmed even if the user determines that they meet the grant rate conditions. This allows the user to understand that the grant rate for future application periods has not yet been applied by the unconfirmed status, thus improving user convenience. For example, in the embodiment, the grant rate is confirmed when the confirmation timing arrives each month (for example, on the 27th of each month), but if the confirmed status is displayed by the end of the month, the user may mistakenly believe that the grant rate for the following month has already been applied. In this regard, the display control system 1 can prevent user misunderstanding by deliberately displaying the grant rate for the following month, which is actually confirmed, as unconfirmed. Since the confirmation timing is before the start of the application period, the display control system 1 can confirm the grant rate with ample time. 【0166】 Furthermore, the display control system 1 includes tabs T20 corresponding to each of the multiple application periods, and displays the award rate screen SC2 on the user terminal 20 with the tab T20 corresponding to the application period corresponding to the current measurement period selected by default. The display of the award rate screen SC2 switches based on the user's operation on each of the multiple application period tabs. This makes it easier for the user to grasp the information of the application period corresponding to the current measurement period, so the display control system 1 can improve user convenience. For example, the user does not need to switch tabs T20 to grasp the information of the application period corresponding to the current measurement period, so the display control system 1 can reduce the user's operational burden. 【0167】 Furthermore, the display control system 1 displays the grant rate screen SC2 on the user terminal 20, which shows the grant rate, status, and information regarding the grant rate conditions for the application period corresponding to the current measurement period among multiple application periods. This allows the user to grasp more detailed information for the application period corresponding to the current measurement period, thus improving user convenience. For example, the display control system 1 displays the difference, such as "2 more times to achieve" or "1 more time to achieve," only for the application period corresponding to the current measurement period on the grant rate screen SC2. The display control system 1 does not display the difference on the grant rate screen SC2 for application periods that do not correspond to the current measurement period, even if the user does not meet the grant rate conditions. By displaying the difference on the grant rate screen SC2 in conjunction with the current measurement period, the display control system 1 can efficiently present the difference to the user. In addition, since the display control system 1 only displays the difference for the application period corresponding to the current measurement period, the processing load can be reduced. 【0168】 Furthermore, the display control system 1 displays a grant rate screen SC2 on the user terminal 20, showing the difference until the user meets the grant rate conditions, for the application period among the multiple application periods in which the user does not meet the grant rate conditions, and which corresponds to the current measurement period. This allows the user to understand how much more is needed to meet the grant rate conditions from the difference on the grant rate screen SC2, thus improving user convenience. For other measurement periods that are not the current measurement period (for example, measurement periods that have already ended or measurement periods that have not yet started), the difference is not displayed, so the display control system 1 does not perform processing to display unnecessary information, thereby reducing the processing load. 【0169】 Furthermore, the current application period overlaps with the measurement period corresponding to at least one application period after the current one. Multiple application periods include the current application period and the one after it. The display control system 1 displays an award rate screen SC2 on the user terminal 20, which can display the award rate and status for each of the current application period and the one after it. This allows the user to grasp the award rate and status for these particularly important application periods, thus improving user convenience. 【0170】 Furthermore, the display control system 1 displays an award rate screen SC2 on the user terminal 20, which includes tabs T20 corresponding to each of the multiple application periods, with the award rate and status placed in the headings of each tab T20. When the user selects any of the tabs T20 corresponding to each of the multiple application periods, the display control system 1 displays details regarding the application period corresponding to that tab T20 on the award rate screen SC2. As a result, the user can grasp the award rate and status by the headings of the tabs T20, thus improving user convenience. 【0171】 [6. Variant] This disclosure is not limited to the embodiments described above. This disclosure may be modified as appropriate without departing from the spirit of this disclosure. 【0172】 [6-1. Variation 1] For example, the grant rate and status may be displayed on screens other than the grant rate screen SC2 described in the embodiment. Modification 1 describes the payment completion screen as an example of another screen. The payment completion screen is a screen that indicates that payment based on a predetermined payment method has been completed. When a user makes a payment using a payment app, the payment completion screen is displayed in the payment app. When a user makes a decision using a browser instead of a payment app, the payment completion screen is displayed in the browser. The payment completion screen may also be displayed in a program other than the payment app and browser (for example, another app different from the payment app). 【0173】 Figure 12 shows an example of a payment completion screen in Modification 1. The top screen SC1 on the left side of Figure 12 is the same as the top screen SC1 on the left side of Figure 2. For example, when a member's terminal reads the payment code C10, the payment is executed according to the flow described in the embodiment. Once the payment is completed, the display control unit 103 displays a payment completion screen SC3 on the user terminal 20, as shown on the right side of Figure 12, indicating that the payment has been completed. In the example on the right side of Figure 12, the payment completion screen SC3 shows the name of the merchant where the payment was made, the date and time of the payment, and the payment amount. 【0174】 The display control unit 103 in Modified Example 1 displays a payment completion screen SC3, which indicates that payment has been completed based on a predetermined payment method, as a payment rate screen on the user terminal 20, showing the payment completion screen SC3, which displays the payment rate and status. The payment rate screen according to this disclosure is a concept that encompasses the payment rate screen SC2 described in the embodiment and the payment completion screen SC3 described in Modified Example 1. The reference numeral "SC2" is omitted in the section describing the payment rate screen, which is a concept that encompasses these two. 【0175】 Note that other screens besides the reward rate screen SC2 and the payment completion screen SC3 may correspond to the reward rate screen. For example, the other screen may be a screen displayed when a user interface part other than icon I13 is selected in the payment app, a screen of another app other than the payment app (for example, a points service app), or a screen displayed in a browser. The reward rate screen is a concept that encompasses these other screens as well. Any screen that shows the reward rate and status should correspond to the reward rate screen. 【0176】 In the example on the right side of Figure 12, the display control unit 103 causes the user terminal 20 to display a payment completion screen SC3 that shows the grant rate (currently applied grant rate) for the current application period (e.g., the month of the payment date and time) and a status indicating that the grant rate has been finalized. The display control unit 103 causes the user terminal 20 to display the payment completion screen SC3 by sending display data for the payment completion screen SC3 showing the grant rate and status to the user terminal 20. For example, the display control unit 103 obtains the currently applied grant rate based on the point database DB2. The display control unit 103 then displays the payment completion screen SC3 on the user terminal 20 that shows the obtained grant rate and a status indicating that the grant rate has been finalized (in the example on the right side of Figure 12, a "Finalized" icon). 【0177】 The display control unit 103 may also display a payment completion screen SC3 on the user terminal 20 that shows the grant rate for the future application period and a status indicating that the grant rate has not yet been determined. For example, when a payment is made, the grant rate determination unit 102 determines the grant rate for the future application period in the same manner as in the embodiment. The grant rate determination unit 102 may also display a payment completion screen SC3 on the user terminal 20 that shows the determined grant rate and a status indicating that the grant rate has not yet been determined (for example, an "undetermined" icon). 【0178】 Furthermore, the display control unit 103 may cause the user terminal 20 to display a payment completion screen SC3 that shows the grant rate for each of the multiple application periods and the status indicating whether or not the grant rate has been determined. For example, the display control unit 103 may cause the user terminal 20 to display a payment completion screen SC3 that shows the grant rate for the current application period and the status indicating that the grant rate has been determined, and the grant rate for future application periods and the status indicating that the grant rate has not been determined. 【0179】 In the modified example 1, the display control system 1 displays the payment completion screen SC3, which shows the grant rate and status, as the grant rate screen on the user terminal 20. This allows the user to check the grant rate and status on the payment completion screen SC3, which they particularly want to check, thus improving user convenience. 【0180】 The display control unit 103 may also display a payment completion screen SC3 showing the award rate on the user terminal 20 without showing the status. In this configuration, the user can confirm the award rate for the payment they have made through the payment completion screen SC3, thus improving user convenience. Even when the user cannot confirm the status on the payment completion screen SC3 but can confirm the award rate, the display control system 1 can improve user convenience as it makes it easier for the user to understand the award rate. This disclosure also includes configurations that solve other problems, such as making it easier for the user to understand the award rate, without solving the problems described in the section on problems the invention aims to solve. Such configurations are also within the scope of this disclosure. 【0181】 [6-2. Variation 2] For example, if the user does not meet the reward rate conditions, the display control unit 103 may display a payment completion screen SC3 on the user terminal 20, which indicates that payment based on the payment method has been completed and includes condition information regarding the reward rate conditions. The condition information may be a link to the reward rate screen SC2, information indicating the reward rate conditions themselves, or other information. The condition information may be characters, numbers, other symbols, images, or a combination thereof. For example, the condition information may be information that the user needs to meet the reward rate conditions. The condition information may also be information relating to the reward rate conditions described in the embodiment. 【0182】 In Modification 2, we take the example where the payment completion screen SC3 is not the award rate screen related to this disclosure. That is, in Modification 2, the payment completion screen SC3 does not have to include at least one of the award rate and the status. The payment completion screen SC3 may include the award rate but not the status, may include the status but not the award rate, or may not include both the award rate and the status. In Modification 2, as in Modification 1, the payment completion screen SC3 may correspond to the award rate screen related to this disclosure. In this case, the payment completion screen SC3 includes the award rate and the status, as in Modification 1. 【0183】 Figure 13 shows an example of the payment completion screen SC3 in Modification 2. As shown on the left side of Figure 13, the display control unit 103 displays the payment completion screen SC3 on the user terminal 20, which shows the reward rate for the current application period (for example, the message "The reward rate for electronic money payments this month is 1.0%") and condition information that is a link to the reward rate screen SC2 (for example, the message "How to make the reward rate 1.5% >"). When the user selects the link on the payment completion screen SC3, the display control unit 103 transitions the user terminal 20 to the reward rate screen SC2, as shown on the right side of Figure 13. 【0184】 Note that the links included in the payment completion screen SC3 are not limited to the example in Figure 13. For example, the links may include links containing messages different from those in Figure 13, links embedded in images such as banners instead of messages, or other types of links. The links include information that can identify the award rate screen SC2. For example, the links may include the URL of the award rate screen SC2, the ID assigned to the award rate screen SC2, or other information. The data for the payment completion screen SC3 and the links are stored in advance in the data storage unit 100. The display control unit 103 generates display data for the payment completion screen SC3, including the links, based on this data and sends it to the user terminal 20, thereby displaying the payment completion screen SC3 on the user terminal 20. 【0185】 In the modified example 2, the display control system 1 displays a payment completion screen SC3 containing condition information on the user terminal 20 if the user does not meet the grant rate conditions. This allows the user to check the condition information on the payment completion screen SC3, which is of particular interest to them, thus improving user convenience. 【0186】 [6-3. Modified Example 3] Figure 14 shows an example of the payment completion screen SC3 of Modification 3. As shown in Figure 14, the display control unit 103 may display the payment completion screen SC3, which does not include condition information, on the user terminal 20 when the user meets the grant rate conditions. The payment completion screen SC3 of Modification 3 differs from Modification 2 in that it does not include condition information. The display control unit 103 displays the payment completion screen SC3 of Modification 2 on the user terminal 20 when the user meets the grant rate conditions. 【0187】 In the modified example 3, the display control system 1 displays a payment completion screen SC3 without condition information on the user terminal 20 when the user meets the reward rate conditions. This is because users who meet the reward rate conditions are likely to already understand the mechanism of the reward rate conditions and may not need the condition information, so the display control system 1 can improve the convenience for such users. For example, since condition information is not displayed on the payment completion screen SC3, the display control system 1 can effectively utilize the display space on the payment completion screen SC3. The display control system 1 can display other information, such as advertisements, on the payment completion screen SC3 instead of the status. 【0188】 [6-4. Modification 4] For example, as explained to some extent in Modification 2, the condition information may be a link to the grant rate screen SC2. The grant rate determination unit 102 in Modification 4 determines the grant rate based on usage information for each of the multiple measurement periods. This is as explained in the embodiment. As explained to some extent in Modification 2, the display control unit 103 in Modification 4 transitions the user terminal 20 to the grant rate screen SC2, which shows the grant rate and status determined based on the current measurement period among the multiple measurement periods, when a link is selected on the payment completion screen SC3. 【0189】 In the modified example 4, the condition information is a link to the award rate screen SC2. The display control system 1 determines the award rate based on usage information for each of the multiple measurement periods. When the link is selected on the payment completion screen SC3, the display control system 1 transitions the user terminal 20 to the award rate screen SC2, which shows the award rate and status determined based on the current measurement period among the multiple measurement periods. This allows the user to transition the user terminal 20 from the payment completion screen SC3 to the award rate screen SC2, thereby improving user convenience for the display control system 1. 【0190】 [6-5. Other variations] For example, the above variations may be combined. 【0191】 For example, the functions described as being implemented by the payment server 10 may be implemented by the user terminal 20 or another computer. The functions described as being implemented by the payment server 10 may be shared among multiple computers. For example, if a points server exists separately from the payment server 10, the functions described as being implemented by the payment server 10 may be implemented by the points server. The functions may be shared between the payment server 10 and the points server. 【0192】 [7. Addendum] For example, the display control system can also be configured as follows: 【0193】 (1) A usage information acquisition unit that acquires usage information regarding a user's use of a specified service, A reward rate determination unit determines a reward rate for benefits granted by using a predetermined payment method, based on the aforementioned usage information, which varies depending on whether the user meets predetermined reward rate conditions and is determined at a predetermined confirmation timing.

(2) The aforementioned rate determination unit, The system determines at a predetermined timing whether the user satisfies the grant rate conditions. If it is determined that the user does not meet the grant rate conditions, the first grant rate is determined as the grant rate.

The display control unit, If it is determined that the user does not meet the grant rate conditions, the grant rate screen showing the first grant rate and the status will be displayed on the user terminal. When it is determined that the user meets the grant rate conditions, the grant rate screen showing the second grant rate and the status is displayed on the user terminal.
