(Individual service 2)
The individual service 2 is premised on the fact that the location information of each client terminal 250 is periodically transmitted to the main system 300 in advance. This position information is an example of redemption information in the present invention. Then, when the individual service 2 is selected in the client A, the following processing is executed. First, as shown in FIG. 5, the client A accepts the input of the remittance condition from the user a (S2.1). The remittance conditions include the range of remittance, the total amount of remittance, and the message associated with the remittance to extract the user to whom the remittance is to be sent. The transmission range corresponds to the condition regarding the position information of the user to be remittance, and is a range based on the position of the client A. The position information in this case is an example of the designated information in the present invention. For example, the transmission range may be a range that is less than or equal to a predetermined distance from the position of the client A, or corresponds to a specific direction (for example, a direction from the east-southeast direction to the east-southwest direction) when viewed from the position of the client A. It may be a range. The transmission range may be input by the user a specifying a specific range on the map displayed on the display of the client A through the touch panel, or is input based on the direction in which the user a holds the client A. You may. The holding direction may be detected based on, for example, an acceleration sensor mounted on the client A. Further, the direction may be input based on the mode in which the user a swings the client A while the map is displayed on the display of the client A. Further, in the client A, by selecting one of the beacons in which the position information is registered in advance as the reference beacon and inputting an arbitrary distance, a range within an arbitrary distance from the reference beacon is designated as the transmission range. May be good. Further, the transmission range may be input by combining the input of the range by these methods and the input of the distance by inputting a numerical value or the like. It is assumed that the user b is a user existing within the transmission range.

Next, the client A transmits the input remittance condition to the main system 300 (S2.2). Next, the main system 300 extracts users corresponding to the transmission range included in the remittance conditions transmitted from the client A (S2.3). Specifically, the main system 300 searches for the user information on condition that the position information included in the user information corresponds to the transmission range. Next, the main system 300 transmits the number of extracted user information extracted in S2.3 to the client A (S2.4). Next, the client A displays on the display the number of extractions transmitted from the main system 300 and the remittance amount per person obtained by dividing the total remittance amount input in S2.1 by the number of extractions (S2.5). Next, the client A accepts an input for the user a to approve the extraction number and the remittance amount displayed in S2.5 (S2.6). If the user a does not approve in S2.6, the processing of the individual service 2 ends. Next, the client A transmits the approval result in S2.6 to the main system 300 (S2.7). In response to this, the main system 300 executes the remittance of virtual currency as an in-system transaction to the user corresponding to all the user information extracted in S2.3 (S2.8). .. The user of the remittance destination includes user b.

Next, the main system 300 transmits the message included in the remittance condition to the communication destination (for example, SNS_ID) included in each user information extracted in S2.3 (S2.9). The message is an example of redemption information in the present invention. The client B displays the message transmitted from the main system 300 on the display (S2.10).

By using the individual service 2, the user a can, for example, remit virtual currency to a user who is within a predetermined distance from his / her store and also send a time sale notification.

(Individual service 3)
In the individual service 3, as shown in FIG. 6, first, the client A accepts the input of the remittance condition from the user a (S3.1). The remittance condition includes an attribute condition indicating an attribute condition for extracting a user to be remittance destination, a total amount of remittance, the number of users to be remittance destination, and a message associated with the remittance. It is assumed that the user b is a user who corresponds to the attribute condition. Next, the client A transmits the input remittance condition to the main system 300 (S3.2). Next, the main system 300 extracts a user having an attribute corresponding to the attribute condition included in the remittance condition transmitted from the client A as in S1.3 (S3.3). Next, the virtual currency is remitted to the user corresponding to all the user information extracted in S3.3 in the same manner as in S1.4 (S3.4). The user of the remittance destination includes user b. Next, the main system 300 transmits the message included in the remittance condition to the communication destination (for example, SNS_ID) included in each user information extracted in S3.3 (S3.5). The message is an example of redemption information in the present invention. The client B displays the message transmitted from the main system 300 on the display (S3.6).

Next, the client B accepts an input from the user b as to whether or not to approve the provision of the location information (S3.7). In S3.7, when the input to the effect that the approval is not made is made (S3.8, NO), the processing in the client B ends. When the input to approve is made in S3.7 (S3.8, YES), the client B transmits the result of approval to provide the location information to the main system 300 (S3.9). The main system 300 generates a user list including a plurality of user IDs to which the approval result is transmitted, based on the approval result transmitted from the client terminal 250 including the client B in this way (S3.10). This user list is retained in the database for a certain period of time proportional to the amount of remittance executed in S3.4. After a certain period of time, the user list is deleted from the database, and the individual service 3 is terminated.

Next, the client B periodically transmits the position information of the client B to the main system 300 (S3.11). This position information is an example of redemption information in the present invention. The main system 300 stores the location information periodically transmitted from the client terminal 250 including the client B as attribute information in the database in association with the user ID transmitted from the client terminal 250 (S3.12). Next, the main system 300 transmits the location information regarding the user ID included in the user list stored in the database to the client A (S3.13). When the client A receives the location information from the main system 300, the client A displays a notification regarding the location information on the display (S3.14). The position information of S3.13 may be transmitted periodically, and the position information may be displayed periodically in S3.14. Further, the attribute information of the user corresponding to the position information may be transmitted from the main system 300 to the client A together with the position information, and the attribute information may be displayed on the display of the client A together with the position information. Further, in S3.13, regarding the client terminal 250 that has approached within a predetermined distance from the client A based on each position information of the client terminal 250, the fact that the client terminal 250 has approached within a predetermined distance from the client A has been determined from the main system 300 to the client A. It may be transmitted to the user a and the client A may notify the user a to that effect. In the individual service 3, the location information is provided to the main system 300 when the approval is obtained from the user of the remittance destination. Therefore, the meaning of the virtual currency remittance that the location information is transmitted in exchange for the virtual currency remittance is clear to the user of the remittance destination. In addition, the expiration date of the user list is set according to the remittance amount. Therefore, the user of the remittance source is likely to have an incentive to increase the remittance amount of the virtual currency. Further, this tends to generate an incentive for the user of the remittance destination to transmit the location information.
