[Lottery processing]
The lottery process performed by the server device 30 will be explained with reference to the flowchart shown in FIG. 3. Hereinafter, a case will be described in which a user operates the user terminal 10 to start a payment application and performs code payment at a store.

Note that various known techniques can be used as a specific method for code payment, such as user presentation type code payment and store presentation type code payment.
For example, in the case of user-presented code payment, the user terminal 10 causes the display to display a code in which user information such as a user ID is embedded. The store terminal 20 uses a reader to read the code displayed on the user terminal 10, and provides payment information including the read information (user ID, etc.) and information regarding product payment (payment amount, store ID, product ID, etc.) is sent to the payment management server device.
In the case of store-presented code payment, the store terminal 20 causes the display to display a code in which information regarding payment for the product is embedded. Alternatively, the store is provided with a code embedded with information regarding payment for the product in advance. The user terminal 10 reads the code using a camera and transmits payment information including the read information (payment amount, store ID, product ID, etc.) and user information (user ID, etc.) to the payment management server device.

In the server device 30, the information acquisition unit 331 acquires payment information from the payment management server device, and stores this payment information in the lottery history database 324 (step S1). Note that the information acquisition unit 331 may acquire payment information accumulated in the payment management server device at preset predetermined intervals, or may transmit payment information from the payment management server device every time the payment management server device performs payment processing. You may also obtain payment information.

The lottery unit 332 determines, based on the lottery campaign information stored in the lottery database 323, whether there is a lottery campaign that allows a lottery to be performed for the payment information (hereinafter referred to as payment information P) acquired in step S1. Determination is made (step S2).

If there is no lottery campaign in which a lottery can be performed, the lottery flow ends.
On the other hand, if there is a lottery campaign in which a lottery can be held, the classification unit 333 refers to the group group information in the lottery database 323 and determines which group the payment information P belongs to based on any information included in the payment information. It is determined whether the payment information P belongs to, that is, the group to which the payment information P belongs (step S3; classification step).

For example, if the group group information sets group conditions for items related to user information, the classification unit 333 retrieves user information corresponding to the user ID from the user database 321 based on the user ID included in the payment information P. The group to which the payment information P belongs is determined based on this user information.
Furthermore, if the group group information sets group conditions for items related to store information, the classification unit 333 retrieves the store information corresponding to the store ID from the store database 322 based on the store ID included in the payment information P. The group to which the payment information P belongs is determined based on this store information.
Furthermore, if the group group information sets group conditions for items related to product information, the classification unit 333 retrieves product information corresponding to the product ID from the store database 322 based on the product ID included in the payment information P. The group to which the payment information P belongs is determined based on this product information. Note that when the payment information includes a plurality of product IDs, the product information with the largest payment amount may be used among the product information corresponding to the product IDs.
Furthermore, if the group group information sets a group condition for an item related to the payment location, the classification unit 333 uses the payment time location information or The store location in the store information is referred to, and the group to which the payment information P belongs is determined based on either one of these locations.

After determining the group to which the payment information P belongs (hereinafter referred to as the belonging group R) using one of the above methods, the classification unit 333 associates the group ID of the belonging group R with the payment information P and stores it in the lottery history database 324. to be memorized.

The lottery unit 332 acquires the winning probability setting value corresponding to the group R to which it belongs from the lottery database 323, and determines whether the payment information P wins based on this winning probability setting value. That is, the lottery unit 332 conducts a lottery for the payment information P based on the winning probability setting value of the group R to which it belongs (step S4).
Note that the specific method of lottery in step S4 is not particularly limited, and known techniques can be used.
Further, in this step S4, the information acquisition unit 331 acquires lottery result information indicating the result of this lottery, and stores this lottery result information in association with the payment information P in the lottery history database 324. Steps S1 and S4 described above correspond to the information acquisition step of the present invention.

If it is determined that the payment information P is a winning result, the lottery unit 332 grants the user corresponding to the user ID included in the payment information P a benefit according to the benefit information stored in the lottery database 323 ( Step S5). For example, the lottery unit 332 adds electronic money equivalent to X% of the payment amount to the account balance of the user information in the user database 321. Note that step S5 may be performed after any of steps S6 to S8, which will be described later.
On the other hand, if the payment information P has not been won, the process proceeds to the next step S6.

After the lottery for the payment information P is held, the group winning information calculation unit 334 updates the group winning information corresponding to the group R to which the payment information P belongs by referring to the lottery history database 324 (step S6; Group winning information calculation step). Specifically, the group winning information calculation unit 334 calculates group winning information indicating the number of wins or winning probability of the belonging group R based on the lottery result information corresponding to the payment information of the belonging group R.

Next, the probability correction unit 335 determines whether to correct the winning probability set value for each group (step S7). In this embodiment, the probability correction unit 335 compares the group winning information in the lottery history database 324 between groups, and if the difference in the number of winnings between any of the groups is equal to or more than a predetermined number, It is determined that correction is to be performed. On the other hand, the probability correction unit 335 determines that no correction is to be performed if the differences in the number of wins between groups are all smaller than the predetermined number.
Then, when it is determined that the correction is to be performed (step S7; Yes), the probability correction unit 335 corrects the winning probability setting value of at least one of the groups so that the difference in the number of winnings between the groups becomes small. (Step S8).
Note that the specific method for correcting the winning probability setting value is not particularly limited, and known techniques can be used. For example, the winning probability setting value of a group with a large number of wins may be corrected to be low, while the winning probability setting value of a group with a small number of winnings may be corrected to be high. Alternatively, in order to temporarily avoid an increase in the number of wins of a group with a large number of wins, the winning probability setting value of the group may be set to zero for a certain period of time.
On the other hand, if the probability correction unit 335 determines not to perform probability correction (step S7; No), the lottery flow ends.
With the above, the lottery flow ends. According to such a flow, during the lottery campaign, a lottery is held every time a user makes a code payment, and the group winning information for each group is updated at any time.

[Example of process for providing winning distribution information]
An example of the process of providing winning distribution information performed by the server device 30 will be described with reference to the flowchart shown in FIG. 4. Hereinafter, a case will be described in which the user operates the user terminal 10 to start the payment application and performs an operation to request winning distribution information of the lottery campaign Q. In this case, the user terminal 10 transmits a request according to the user's operation to the server device 30. This request includes the lottery campaign ID of the lottery campaign Q desired by the user, information specifying the type of winning distribution information desired by the user, and the user ID.

In the server device 30, the winning distribution information generation unit 336 receives a request from the user terminal 10 (step S11), and generates winning distribution information based on the request (step S12; winning distribution information generation step). The winning distribution information providing unit 337 transmits the winning distribution information generated in step S12 to the user terminal 10 of the user who sent the request (step S13).
Specific examples of step S12 will be described below for each format of winning distribution information.

(Winning distribution information in user-specific format)
When the user terminal 10 requests winning distribution information in a user-specific format, the winning distribution information generation unit 336 generates the user information of the user to whom the winning distribution information is transmitted based on the user ID included in the requested information. get. Then, the winning distribution information generation unit 336 selects a group based on the acquired user information.
Here, the winning distribution information generation unit 336 performs processing according to the group group information corresponding to the lottery campaign Q.

For example, if each group condition item in the group group information is "gender," "age," "place of residence," etc., the winning distribution information generation unit 336 generates a group condition item corresponding to the user attribute of the acquired user information. Select a group.

Further, when the item of each group condition in the group group information is "store category" or "product category", the winning distribution information generation unit 336 calculates the degree of association between the acquired user information payment information and each group condition. The group condition is calculated and the degree of association is equal to or higher than a predetermined value. Specifically, based on the store ID or product ID included in the payment history, the winning distribution information generation unit 336 retrieves from the store database 322 the store category of the store corresponding to the store ID or the store category corresponding to the product ID. Identify the product category of the product. Then, the degree of association between the category group specified from the payment information and the category of each group condition is calculated using a known scoring technique, and a group of group conditions whose degree of association is equal to or higher than a predetermined value is selected.

Further, when the item of each group condition in the group group information is "payment position", the winning distribution information generation unit 336 selects the group of group conditions corresponding to the area including the current position of the acquired user information.

Thereafter, the winning distribution information generation unit 336 acquires the group winning information of the selected group from the lottery database 323, and generates winning distribution information including the winning information of each group. In addition, when a plurality of group group information is set in the lottery campaign Q, a group matching the user information may be selected from each group group information.
As a result, winning distribution information as shown in FIG. 5 is generated. Note that as reference information, group winning information of reference groups other than the group selected based on the user information may be included in the winning distribution information.

(Winning distribution information in ranking format)
Further, when the user terminal 10 requests winning distribution information in a ranking format regarding winning probability, the winning distribution information generation unit 336 refers to the winning probability setting values in the lottery database 323 and selects the winning probability setting values in descending order of winning probability setting values. , it is also possible to generate winning distribution information in which a plurality of group winning information are listed. As a result, winning distribution information as shown in FIG. 6 is generated.
Note that the example shown in FIG. 6 shows a case where the item of each group condition in the group group information is "settlement position". Further, here, it is assumed that the winning probability setting value is adjusted so that the number of winnings among groups is equal.

Furthermore, when the user terminal 10 requests winning distribution information in a ranking format regarding the number of winnings and winning probability, the winning distribution information generation unit 336 refers to the group winning information in the lottery database 323 and selects the winning distribution in order of the number of winnings and the probability of winning. Winning distribution information may be generated in which a plurality of group winning information are listed in descending order of winning probability.

(Winning distribution information in all data display format)
Further, when the user terminal 10 requests the winning distribution information in the all data display format, the winning distribution information generation unit 336 generates the winning distribution information by compiling the group winning information of all the groups into a table or the like.

[Other examples of the process of providing winning distribution information]
Next, another example of the process of providing winning distribution information performed by the server device 30 will be described with reference to the flowchart shown in FIG.
In this example, the winning distribution information providing unit 337 detects a user to whom winning distribution information is to be transmitted (step S21).
For example, the winning distribution information providing unit 337 identifies a store associated with a group in which any of the winning probability setting value, the number of wins, or the winning probability is greater than or equal to a predetermined value, and detects users who are located within a predetermined distance from the store. do.
As a specific example, if the winning probability setting value of a group whose group condition is "the payment location is in area A" is greater than or equal to a predetermined value, a store whose store location is in area A is identified, and the surrounding area of the store is Detect the located user.
In addition, if the number of winners of a group whose group condition is "store category is category B" is more than a predetermined number, the store whose store category is category B is specified, and users located around the store are identified. To detect.

Next, the winning distribution information generation unit 336 generates winning distribution information including group winning information of the group specified in step S21 (step S22).
Thereafter, the winning distribution information providing unit 337 transmits the winning distribution information generated in step S22 to the user terminal 10 of the user detected in step S21 (step S23). At this time, recommendation information recommending code payment at a store related to the group may be transmitted together with the winning distribution information.

[Actions and effects of this embodiment]
In the present embodiment described above, by checking the winning distribution information transmitted from the server device 30 on the user terminal 10, the user can determine the winning expectation level of the group included in the winning distribution information. As a result, the game quality of the lottery campaign can be enhanced while maintaining fairness between users in the form of randomness of the lottery, and the motivation of users to participate in the lottery campaign can be sufficiently increased. As a result, the promotional effect of a campaign using a lottery can be improved.
In addition, the winning distribution information including the number of winnings in each group functions as a positive decision material for stores related to groups with a large number of winnings to decide whether to introduce a code payment system. This will increase the number of stores that have introduced code payments and improve the overall sales promotion effect of stores that have introduced code payment systems.

In this embodiment, the group winning information calculation unit 334 calculates group winning information at any time during the implementation period of the lottery campaign, and the winning distribution information generating unit 336 generates winning distribution information including the latest group winning information. That is, in this embodiment, the winning distribution information is updated in real time during the implementation period of the lottery campaign. This further enhances the gameplay of the lottery campaign.

In this embodiment, the winning distribution information generation unit 336 selects a group based on the user information of the user to whom the winning distribution information is to be transmitted, and generates winning distribution information including group winning information corresponding to the group. Good too.
In this case, by checking the winning distribution information displayed on the user terminal 10, the user can determine his or her own group's winning expectation. This makes it possible to more effectively increase the user's desire to purchase.

In this embodiment, the lottery unit 332 performs a lottery on the payment information based on the winning probability setting value set for the group to which the payment information belongs. Since the probability of winning for each group is set appropriately, the game quality of the lottery campaign is further enhanced.

In this embodiment, the probability correction unit 335 corrects the winning probability setting value so that the difference in the number of winnings between groups becomes small during the implementation period of the lottery campaign.
For example, even if the winning probability setting values are set to the same value between groups, the number of wins will increase as the number of payment information items for a group is larger. Therefore, during the lottery campaign, by correcting the winning probability setting value so that the difference in the number of wins between groups becomes small, it is possible to make the number of wins in each group almost the same. Thereby, fairness between groups can be ensured from the viewpoint of the number of winners.
Furthermore, for a group that has a smaller number of winners than other groups at any given time during the implementation period of the lottery campaign, the winning probability setting value corresponding to the group increases from that time onwards. As a result, the user's expectation of winning for a group with a small number of winners increases, and a high promotional effect is generated for the group.
For example, if payment information is grouped by area (e.g., prefecture) where code payments are made, the number of users from other prefectures will increase, leading to regional revitalization.

[Modified example]
Note that the present invention is not limited to the embodiments described above, but includes the following modifications as long as the object of the present invention can be achieved.

[Modification 1]
In the embodiment described above, the probability correction unit 335 corrects the winning probability setting value so that the difference in the number of wins between groups becomes small, but the present invention is not limited to this.
For example, the winning probability setting value may be corrected so that the number of wins for a specific group designated from the store terminal 20 or the like is greater than the number of wins for other groups.
Alternatively, during the lottery campaign period, the winning probability setting value may not be corrected and may remain at the initially set winning probability setting value.

[Modification 2]
In the embodiment described above, the winning distribution information providing unit 337 detects users who are located within a predetermined distance from a group of stores whose winning probability setting value is a predetermined value or higher, but the method of detecting users is not limited to this.
For example, the winning distribution information providing unit 337 may detect a user who can obtain an upcoming location from a schedule management server device or a user who has searched for a destination using a route search server device.
In this case, the winning distribution information generation unit 336 generates winning distribution information including group winning information of a group related to the user's destination (scheduled location or destination).
