Note that the retransmission may be automatically transmitted after a predetermined period from the initial transmission, or may be manually transmitted upon receiving a user's transmission instruction.

  The business card information exchange server 40 determines whether or not the business card information of the exchange authorized person for the user terminal 10A has been transmitted to the user terminal 10A, and transmits the business card information of the unsent exchange authorized person to the user terminal 10A (step S133). ). As shown in FIG. 3D, in the exchange information storage unit 407, user terminals 10B and 10C are registered as exchange permitters for the user terminal 10A. Since the business card information of the user terminal 10C has already been transmitted to the user terminal 10A in step S125, only the business card information of the user terminal 10B is transmitted to the user terminal 10A here.

  The user terminal 10B transmits a business card information acquisition request to the business card information exchange server 40 after the business card information acquisition request restriction timer activated in step S128 expires (step S134). As shown in FIG. 3D, since the user terminals 10A and 10C are registered as exchange authorized persons for the user terminal 10B in the exchange information storage unit 407, the business card information exchange server 40 stores the business card information of the user terminals 10A and 10C. It transmits to the user terminal 10B (step S135).

  When the exchange permitter update timer activated in step S109 expires, the business card information exchange server 40 deletes the exchange information of the user terminals 10A to 10C from the exchange information storage unit 407 (step S136).

  According to the business card information exchange system 1 according to the first embodiment, a business card information registration request including business card information is received from the user terminals 10B and 10C located in the same area before the exchange candidate determination timer expires. In this case, since the user terminals 10A and 10B are determined as exchange candidates for the user 10A, the user terminal 10A can exchange business card information with a plurality of user terminals 10B and 10C. That is, the user terminal 10A can perform not only one-to-one business card exchange but also one-to-many business card exchange. The user terminals 10B and 10C can also perform one-to-many business card exchange. Thus, according to the business card information exchange system 1, a plurality of business cards can be exchanged between the user terminals 10A to 10C.

  Further, according to the business card information exchange system 1 according to the first embodiment, every time a replacement permission notification for the user terminal 10A is received from the replacement candidate before the replacement permitter update timer expires, the exchange Since the candidate is registered as an exchange permitter for the user terminal 10A and the registered exchange permitter's business card information is transmitted to the user terminal 10A, the business card information of the user terminal 10B or 10C that does not want to exchange the business card with the user terminal 10A Can be prevented from being transmitted to the user terminal 10A.

  Further, according to the business card information exchange system 1 according to the first embodiment, it is determined whether or not the business card information of the exchange authorized person has been transmitted to the user terminal 10A, and the exchange permission that has been determined to be untransmitted. Since the business card information of the person is transmitted to the user terminal 10A, it is possible to prevent the business card information of the same exchange permitter from being transmitted to the user terminal 10A many times.

  Moreover, according to the business card information exchange system 1 according to the first embodiment, since the exchange candidate request from the user terminals 10A to 10C is transmitted after the exchange candidate request limit timer expires, the business card information management It is possible to prevent a useless exchange candidate list request from being transmitted even though no exchange candidate has been determined by the server 40.

  Moreover, according to the business card information exchange system 1 according to the first embodiment, since the business card information acquisition request from the user terminals 10A to 10C is transmitted after the business card information acquisition request limit timer expires, the business card information management It is possible to prevent a useless business card information acquisition request from being transmitted even though the exchange permitter is not registered in the server 40.

(Example of change)
A modification example of the business card information exchange system 1 according to the first embodiment will be described. In the first embodiment, the exchange permission notification transmitted from the user terminal 10 includes transmission permission and / or reception permission. Specifically, the user instruction accepting unit 106 separately accepts a transmission permission instruction and a reception permission instruction for the exchange candidate, and the exchange permission notifying unit 107 transmits the exchange permission notification to the business card information exchange server 40. .

  FIG. 7 is a diagram showing a transmission permitted person and a reception permitted person that are sequentially registered in the exchange information storage unit 407 according to the modified example. In FIG. 7, the user terminal 10B is registered as a transmission permitter for the user terminal 10A and a reception permitter from the user terminal 10A. On the other hand, the user terminal 10A is registered as a permitted person for reception from the user terminal 10B, but is not registered as a permitted person for transmission to the user terminal 10B. In FIG. 7, since the user terminal 10A does not permit transmission to the user terminal 10B, the user terminal 10B cannot receive the business card information of the user terminal 10A.

  As shown in FIG. 7, the exchange permitter update unit 408 registers the transmission permitter and the reception permitter separately in the exchange information storage unit 407, thereby enabling more flexible business card exchange control.

  Although the present invention has been described in detail using the above-described embodiments, it will be apparent to those skilled in the art that the present invention is not limited to the embodiments described herein. The present invention can be implemented as a modified and updated mode without departing from the spirit and scope of the present invention defined by the description of the scope of claims.
