  When there is a purchase request from the first user A's avatar for an item possessed by the second user B's avatar to the transaction management avatar that is programmed in step S1-1, the transaction management server 114 is step S1-2. Then, it is confirmed whether or not there is a digital cash for the item purchase in the basic account of the first user A.

  When the transaction management server 114 confirms that there is a digital cash for the item purchase in the basic account of the first user A in step S1-2, next, the transaction management server 114 sends the transaction management avatar to the second user B in step S1-3. Request movement of items. In step S1-2, if there is no digital cash for item purchase in the basic account of the first user A, the transaction process is terminated. At this time, communication with the financial institution server 115 may be performed, and the first user A's digital cash may be deducted from the financial institution account of the first user A so that the item is purchased.

  When the transaction management server 114 can confirm the movement of the item from the avatar of the second user B to the transaction management avatar in step S1-4, the digital cash for the item purchase from the basic account of the first user A in step S1-5. Secure. The secured digital cash is managed by the purchase digital cash management unit 124. The item moved from the second user B's avatar to the transaction management avatar is managed by the item management unit 125.

  When the transaction management server 114 completes securing the digital cash for the item purchase from the basic account of the first user A in step S1-6, the digital cash for the purchase is stored in the basic account of the second user B in step S1-7. Deposit money.

  The transaction management server 114 notifies the second user B that the digital cash has been deposited in step S1-9 when the payment of the purchased digital cash to the basic account of the second user B is completed in step S1-8. In step S1-10, the item is moved from the transaction management avatar to the first user A avatar. Here, not only the item management database 124 is changed, but also an item moving process in the game, for example, a process of moving an item to the avatar of the first user by a command is performed.

  Next, specific operations on the game of the transaction will be described.

  First, the avatar of the second user B finds a transaction management avatar, and “My user ID is“ 001 ”for the transaction management avatar. Introduce yourself. The transaction management avatar confirms whether or not the user ID is registered in the transaction management server 114.

  The second user B introduces the item to be sold to the transaction management avatar, “Please find the person who buys the item by tomorrow. The item is level X”.

  Next, the second user B operates the avatar to the transaction management avatar, “If you find a person who buys 10 coins α by 3 pm the day after tomorrow, please sell it. Please return the item in front of "."

  The transaction management avatar is “user ID“ 001 ”in response to the sales request from the second user B avatar by the program of the transaction management server 114. Is item A certainly level X? I will try to sell it by 3pm the day after tomorrow. ”Response.

  Next, the transaction management avatar moves with a signboard “I sell items”. Alternatively, standing in a predetermined position. Alternatively, an item store is opened.

  The first user A who wishes to purchase item A looks at the signboard posted by the transaction management avatar, approaches the transaction management avatar, and says to the transaction management butter, “My user ID is“ 002 ”. Introduce yourself to the effect. Here, the transaction management avatar checks whether or not the user ID “002” is registered in the transaction management server 114.

  When purchasing the item, the first user A operates the avatar and makes a purchase request to the effect that “buy the item with 10 currency α”.

  The transaction management avatar acquires the transaction management user ID from the user ID of the service provider using the contract management database 127, and responds to the purchase request from the first user A with respect to the transaction management server 114 by the first user A. Request to secure digital cash equivalent to 10 currency α from the base account.

  When the transaction management server 114 secures a digital cash equivalent to 10 currency α from the basic account of the first user A, the transaction management server 114 notifies the transaction management avatar to that effect. The transaction management avatar delivers the item to the first user A. Further, the transaction management server 114 deposits a digital cash equivalent to 10 currency α into the basic account of the second user B. At this time, the transaction management server 114 refers to the currency conversion table 128, calculates the digital cash corresponding to the currency, and secures the digital cash and deposits the digital cash. This makes it possible to sell items and use the digital cash increased after checkout for other services, and share it among digital cash services.

  In addition, a transaction management avatar returns an item to the 2nd user B at 3:00 pm on the day after tomorrow when exchange is not established.

  As described above, the digital cash for item purchase is deposited from the first user A to the second user B, and the item moves from the second user B to the first user A. It is possible to exchange digital cash and items without fail. Thus, the transaction between the first user A and the second user B is mediated by the transaction management avatar programmed by the transaction management server 114 to mediate the transaction between the first user A and the second user B. You can avoid troubles related to.

  In addition, you may make it communicate with the transaction management server 114 directly, without going through a transaction management avatar.

  FIG. 11 shows a process flowchart of the first modification of the transaction management server 114.

  When there is a contract request for a transaction between the first user A and the second user B, the transaction management server 114 sends the transaction management server 114 to the transaction management server 114 in step S2-1 separately from the service provided by the service providing server 113, for example, When a purchase request is received from the first user A for an item possessed by the avatar of the second user B through an internet connection from a personal computer or mobile terminal, the item is purchased in the basic account of the first user A in step S2-2. Check if there is a minute digital cash.

  When the transaction management server 114 confirms that there is a digital cash for the purchase of the item in the basic account of the first user A in step S2-2, next, the item from the basic account of the first user A in step S2-3. Secure digital cash for purchases. The secured digital cash is managed by the purchase digital cash management unit 124.

Next, the transaction management server 114 notifies the second user B that the item purchase digital cash has been secured in step S2-4. At this time, the notification to the second user B includes an instruction that prompts the first user A to move the item. The second user B moves the item to the first user A in response to a notification from the transaction management server 114 that the item purchase digital cash has been secured.
Thereby, the first user A can use the item. When the item is moved from the second user B, the first user A notifies the transaction management avatar that the item has been moved from the second user B. When an item purchase request is received, the first user A is instructed to notify the user A when receiving an item from the second user B from the transaction management avatar.

  When there is a notice from the first user A that the item has been received from the second user B through the transaction management avatar in step S2-5, the transaction management server 114 receives the basic account of the second user B in step S2-6. The purchase digital cash management unit 124 deposits the purchase digital cash.

  The item movement notification / processing to the service provider 113 is performed by the user if the user must perform the transaction, but if the transaction management server 114 can act for a contract with the service provider 113, the transaction is performed. The management server 114 may be substituted.

  Next, specific operations on the game of the transaction will be described.

  First, the avatar of the second user B who sells an item moves with a signboard “I sell items”.

  The avatar of the first user A who wants to purchase the item and the avatar of the second user B who sells the item are “my user ID is“ 001 ”. Buy items with 10 coins α. ”Is presented.

  The second user B responds to the purchase request “My user ID is“ 001 ”. Item is level X. ”Introduces self-introduction and items.

  The avatar of the first user A confirms to the avatar of the second user B that “ID001, the item is indeed level X. The selling price is 10 currency α.”

  After confirming in the exchange window, the second user B requests the transaction management server 114 to secure a digital cash equivalent to 10 currency α from the basic account of the first user A.

  The transaction management server 114 secures a digital cash equivalent to 10 currency α from the basic account of the first user A and notifies the second user B of it. The second user B's avatar passes the item to the first user A's avatar.

  As described above, the digital cash for item purchase is deposited from the first user A to the second user B, and the item moves from the second user B to the first user A. Exchange of digital cash and items is surely performed. Thus, the trouble regarding the transaction between the 1st user A and the 2nd user B can be avoided by mediating the transaction of the 1st user A and the 2nd user B by a transaction management avatar.

  Next, a second modification of the transaction management server 114 will be described.

  In this modification, a transaction for transferring a user ID for receiving a service in the service providing server 113 from the user B to the user A will be described.

  FIG. 12 shows a process flowchart of the second modification of the transaction management server 114.

  First, when there is a request to transfer the user ID of the second user B to the first user A in step S3-1, the transaction management server 114 purchases the user ID in the basic account of the first user A in step S3-2. Check if there is any digital cash.

  When there is a digital cash for purchase of the user ID in the first user A's base account in step S3-2, the transaction management server 114 receives a digital cash for the purchase of the user ID from the base account of the first user A in step S3-3. Secure. The digital cash for purchasing the user ID from the basic account of the first user A is managed by the purchase digital cash management unit 124. Then, the transaction management server 114 describes the contract ID in the contract management database 127 and sets the status to “2”, that is, “contract processing in progress”. In step S3-2, when there is no digital cash for the purchase of the user ID in the basic account of the first user A, the process ends. Alternatively, communication with the financial institution server 115 may be performed, and the first user A may be withdrawn from the account of the financial institution.

  When the transaction management server 114 completes securing the digital cash for the purchase of the user ID from the basic account of the first user A in step S3-4, the transaction management server 114 notifies the second user B that the digital cash is secured in step S3-5. I do.

  The transaction management server 114 requests the user ID and password from the second user B in step S3-6. The second user B notifies the transaction management server 114 of the user ID and password corresponding to the request from the transaction management server 114.

  When the user ID and password are notified from the second user B in step S3-7, the transaction management server 114 connects to the service providing server 113 using the user ID and password notified in step S3-8, and confirms the operation. I do. The user ID and password are managed by the user ID management unit 127.

  When the operation management can be confirmed in step S3-9, the transaction management server 114 changes the password in step S3-10, and notifies the first user A of the user ID and the changed password in step S3-11. When the user ID and the changed password are notified from the transaction management server 114, the first user A notifies the transaction management server 114 that the user ID and the changed password have been received.

  Upon receiving notification that the user ID and the changed password have been received from the first user A in step S3-12, the transaction management server 114 stores the purchase amount of the user ID in the basic account of the second user B in step S3-13. Deposit your digital cash.

  As described above, the user ID necessary for receiving the service provided by the service providing server 113 is transferred from the second user B to the first user A.

  When the second user B sells the item to the first user A, money passes from the first user A to the second user B. Accordingly, the transaction management server 114 deposits a digital cash proportional to money into the second user B's basic account.

  According to this modification, a user ID transaction can be easily performed.

  Moreover, the transaction management server 114 can exchange the money used in each service equivalently between different service providers by using the money conversion table 128. As a result, the money used in one service can be used in another service.

  Moreover, although the process which trades using an avatar was demonstrated in a present Example, you may make it trade using an item transaction screen.

  FIG. 13 shows a transaction registration screen, and FIG. 14 shows a transaction screen. 13A shows a login screen, FIG. 13B shows a sales registration screen, FIG. 13C shows a purchase registration screen, FIG. 14A shows a purchase request list screen, and FIG. 14B shows The sales wish list screen is shown.

  For example, when an item transaction button or the like is operated, a login screen as shown in FIG. 13A is displayed, and when a user ID and password are entered in the login screen shown in FIG. 13A, the login screen shown in FIG. Such an item sales screen or an item purchase screen as shown in FIG. 13C is displayed.

  When wishing to sell an item, on the item sales screen shown in FIG. 13B, by inputting an item ID for identifying a sales item, a desired sales currency α, a sales user ID, and clicking a request button, Sales item is registered.

  When purchasing an item, enter the purchase item ID, purchase currency α, purchase user ID for identifying the purchase item on the item purchase request screen shown in FIG. 13C, and click the request button. By doing so, the purchase desired item is registered.

  When a purchase request is made, it is registered on a purchase request list screen as shown in FIG. The purchase request list screen displays a list of purchase requester user IDs and purchase purchase currency α for each sale item ID, and a seller who wants to sell an item with the corresponding item ID selects a user from the list display. By clicking the request button, it is possible to conduct a transaction with a purchase applicant who desires an item with the corresponding item ID.

  Further, when a sales request is made, it is registered on a purchase request list screen as shown in FIG. The purchase request list screen displays a sales request user ID, an item ID, and a sales request currency α. The purchase applicant can make a transaction with the item seller who owns the purchased item by selecting a sales user corresponding to the item ID and purchase currency α desired to purchase and clicking the request button.

  The conversion rate of digital cash between services is derived from the value of currency (money) objectively calculated by examining the price of items in each service from various information such as an auction site. Further, it may be automatically calculated from an average price of an auction site for a specific item in each service.

  In addition, this invention is not limited to the said Example, It cannot be overemphasized that a various modified example can be considered in the range which does not deviate from the summary of this invention.
