<Embodiment>
(Outline of business card information management system)
1 is a schematic block diagram showing an example of a business card information management system. The business card information management system 1 includes a business card information management device 10, a user terminal 20, a card 30 as a tangible object, and an administrator terminal 40. The business card information management system 1 is a system used to manage business card information indicating user attributes. The business card information management device 10, the user terminal 20, and the administrator terminal 40 are connected to each other via a communication network 50 so as to be able to communicate with each other.

The business card information management device 10 receives and stores various information such as user information (e.g., email address, password, account information for external services, etc., as described below) and business card information (as described below) from the user terminal 20. The business card information management device 10 also stores connection information (as described below) indicating connections between users, and community identification information (as described below) that identifies the community to which the user belongs among multiple communities. The business card information management device 10 further displays each piece of information, such as the business card information, on the user terminal 20 or the administrator terminal 40.

The business card information includes at least information indicating the attributes of the user, and includes information about the user. Information about the user is, for example, the user's personal information. The business card information may include information such as the name, company name, job title, hometown, hobbies, career/educational background, line of business/industry, telephone number, and email address.

The business card information management device 10 may function, for example, as a server that provides a (Web) application for managing users' business card information as a service.

(User terminal 20)
In response to a user's operation, the user terminal 20 transmits various information such as user information and business card information to the business card information management device 10. In addition, the user terminal 20 receives various information such as business card information from the business card information management device 10 and displays it on the display of the user terminal 20.

The user terminal 20 also obtains information indicating the storage location of the business card information from the tag 31 included in the card 30 by short-range wireless communication. The short-range wireless communication may be, for example, NFC (Near Field Communication). The user terminal 20 includes at least one of a smartphone, a tablet, and a PC (personal computer).

(Card 30)
The card 30 is used by a user as a so-called digital business card. The card 30 is an example of a tangible object. The card 30 may be a plastic card equipped with a tag 31 and an antenna coil. The tag 31 may be, for example, an NFC tag. A card URL (Uniform Resource Locator) indicating a storage location on the Internet of the user's business card information is recorded on the tag 31. The card URL is an example of storage location information indicating a storage location of the user's business card information.

Card 30 is a tangible object that represents the business card information of the user, and is owned and used by each user. An example of its use is outlined below.

For example, when user A obtains card 30 as a digital business card from the operator of the business card information management system 1, he or she first executes short-distance wireless communication between the user terminal 20 (user terminal A) that he or she operates and card 30. As a result, user A issues his or her own account (user identification information) according to a processing flow described later, and user information (described later) and user identification information, etc. are recorded in the business card information management device 10. When user A issues the account, he or she can input (edit) his or her own business card information on a screen such as that shown in FIG. 11 described later. After issuing the account, user A inputs the business card information into user terminal 20 (user terminal A). When the business card information is input into user terminal 20 (user terminal A), user terminal 20 (user terminal A) transmits the business card information to business card information management device 10, and the business card information is recorded in the business card information management device 10.

Then, when exchanging business cards with another user, for example, user B, user A, instead of handing over a paper business card, executes short-range wireless communication between his/her own card 30 as a digital business card and the user terminal 20 (user terminal B) operated by user B. As a result, the user terminal 20 (user terminal B) operated by user B receives the business card information of user A from the business card information management device 10, and displays the business card information of user A on the display of user terminal B.

(Administrator terminal 40)
The administrator terminal 40 is a terminal for managing a community to which a user belongs among a plurality of communities. A community is a group of people connected by a common purpose, interest, region, etc. Examples of communities include salons (including online salons), study groups, business networking meetings, study groups, and organizations such as companies. A community may also be a gathering for business communication.

Each community may have an owner, and may have an administrator appointed by the owner (a person who has been granted authority by the owner). The administrator may be the owner himself. There may be one or more administrator terminals 40. That is, an administrator terminal 40 may be provided for each community. The administrator terminal 40 may function as a client terminal for a web application for a management screen provided by the business card information management device 10 as a server.

The administrator terminal 40 includes at least one of a smartphone, a tablet, and a PC (personal computer). The owner (administrator) and the user (e.g., user A) may be the same person. In other words, the owner may manage a community to which multiple users belong, while also holding a card 30 as a user and exchanging business card information with other users. In this case, the owner may use a user terminal 20 (e.g., a smartphone) as the administrator terminal 40.

Figure 2 is a diagram showing an example of the front side of a card. The front side of the card 30 (a so-called digital business card) shown in Figure 2 has printed thereon the name of the community (e.g., "Group A") related to the community identification information linked to the card information of the card 30 (described later). Note that since the function of the digital business card is fulfilled by the tag 31, the printed content may be different or may be blank.

Figure 3 is a diagram showing an example of the back side of a card. A two-dimensional code in which a card URL (storage location information) is encoded is printed on the back side of the card 30 shown in Figure 3. The two-dimensional code is an example of code information that includes a card URL. The two-dimensional code may be, for example, a QR code (registered trademark).

The user terminal 20 may obtain the card URL recorded on the card 30 by short-range wireless communication with the tag 31 included in the card 30, or by reading and decoding the code information displayed on the card 30.

(Hardware configuration example)
4 is a diagram showing an example of the hardware configuration of the business card information management device 10. The business card information management device 10 includes a bus 1010, a processor 1020, a memory 1030, a storage device 1040, an input/output interface 1050, and a network interface 1060.

The bus 1010 is a data transmission path for the processor 1020, memory 1030, storage device 1040, input/output interface 1050, and network interface 1060 to transmit and receive data to and from each other. However, the method of connecting the processor 1020 and other components to each other is not limited to a bus connection.

The processor 1020 is a processor realized by a CPU (Central Processing Unit) or a GPU (Graphics Processing Unit), etc.

Memory 1030 is a main storage device realized by RAM (Random Access Memory) or the like.

The storage device 1040 is an auxiliary storage device realized by a removable medium such as a hard disk drive (HDD), a solid state drive (SSD), a memory card, or a read only memory (ROM), and has a recording medium. The recording medium of the storage device 1040 stores program modules that realize each function of the business card information management device 10 (for example, the user identification information storage unit 11, the community information storage unit 13, and the display control unit 14 described below). The processor 1020 loads each of these program modules into the memory 1030 and executes them, thereby realizing each function corresponding to the program module. The storage device 1040 also functions as a device for storing various information such as user identification information and business card information.

The input/output interface 1050 is an interface for connecting the business card information management device 10 to various input/output devices.

The network interface 1060 is an interface for connecting the business card information management device 10 to a network. This network is, for example, a LAN (Local Area Network) or a WAN (Wide Area Network). The method for connecting the network interface 1060 to the network may be a wireless connection or a wired connection. The business card information management device 10 may communicate with the user terminal 20 and the administrator terminal 40 via the network interface 1060.

The user terminal 20 and the administrator terminal 40 may have the hardware configuration shown in FIG. 4, similar to the business card information management device 10.

(Examples of various information)
Next, a description will be given of specific examples of various information stored in the business card information management device 10. Note that the data structure (data table) shown below is an example.

Figure 5 is a diagram showing an example of a data table including user identification information. User identification information 801 is generated by the user identification information storage unit 11 described later. User identification information 801 may include a "user ID" as an item. The value of the "user ID" item is an identifier for identifying a user.

The data table including the user identification information 801 may also include user information 806. The user information 806 is information related to the user. When the user issues an account, the business card information management device 10 acquires information that the user inputs to the user terminal 20 for account issuance from the user terminal 20 as user information 806. The user information 806 is also information that is unique to the user and is defined by the user. The user information 806 may include the items "email address" and "password". The value of the item "email address" is the user's email address. The value of the item "password" is the user's password. The combination of the user's email address and password may be used for authentication when logging in to a web application provided by the business card information management device 10.

Figure 6 is a diagram showing an example of a data table including card information. Card information 802 is an example of tangible object information that is information about a tangible object and includes storage location information. Tangible object information is also information for identifying (distinguishing) tangible objects. Card information 802 is information that is linked in advance to each card 30 by the operator of the business card information management system 1. Card information 802 may include the items "card ID" and "card URL (storage location information)." The value of the item "card ID" is an identifier for identifying the card 30. The value of the item "card URL" is the URL recorded in the tag 31 included in the card 30 or the two-dimensional code.

The data table including the card information 802 may also include community identification information 804, which will be described later. That is, the card information 802 may be linked to a "community ID" as the community identification information 804. The value of the "community ID" item is an identifier for identifying the community to which the user belongs, which is linked to the card information 802. The value of the "community ID" item in FIG. 6, "-", indicates that the card 30 is not linked to a community.

The data table including the card information 802 may also include user identification information 801 (user ID). When the user identification information storage unit 11 described below generates the user identification information 801, the user identification information storage unit 11 stores the card information 802 in association with the user identification information 801 (user ID). Note that the "-" value for the "User ID" item in FIG. 6 indicates that the card is not associated with a "User ID".

Figure 7 is a diagram showing an example of a data table including connection information. Connection information 803 is generated by the connection information storage unit 12 described below. Connection information 803 may include items such as "connection ID", "first user ID", and "second user ID". The value of the item "connection ID" is an identifier for identifying connection information.

The value of the item "First user ID" and the value of the item "Second user ID" are identifiers for identifying the users whose connection information is recorded. For example, when user A (whose user ID in FIG. 5 is "U001") and user B (whose user ID in FIG. 5 is "U002") are connected, the connection ID is written as "X001", the first user ID as "U001", and the second user ID as "U002" in the data table containing the connection information.

FIG. 8 is a diagram showing an example of a data table including community identification information. The community identification information 804 is information prepared in advance by the operator of the business card information management system 1. The community identification information 804 is information for identifying (distinguishing) the community to which the user belongs among multiple communities. In an embodiment, the community identification information 804 may include a "community ID" as an item. The value of the item "community ID" is an identifier for identifying the community to which the user belongs. As will be described later, the community information storage unit 13 associates and stores the user identification information 801 (user ID) with the community identification information 804, thereby writing values into the data table shown in FIG. 8.

Figure 9 is a diagram showing an example of a data table including community owner information. Community owner information 805 is generated, for example, by registering the community owner's email address and password in the business card information management device 10. Specifically, a management site for each community is prepared in advance by the operator of the business card information management system 1, and the management site can be accessed by setting and registering the email address and password. At this time, community owner information 805 is generated.

The community owner information 805 may include the following items: "owner email address," "owner password," and "management screen URL." Furthermore, a data table that includes the community owner information 805 includes a "community ID (community identification information 804)." In this way, the community owner information 805 and the community identification information 804 are linked.

The value of the item "Owner email address" is the email address defined by the community owner. The value of the item "Owner password" is the password defined by the community owner. The combination of the owner email address and owner password may be used for authentication when logging in to the management site.

The value of the item "Management screen URL" indicates the URL of the communication destination (management site) with which the administrator terminal 40 communicates to manage the community information.

(Example of functions)
10 is a diagram showing an example of functions of a business card information management device 10. The business card information management device 10 has, as functional units, a user identification information storage unit 11, a connection information storage unit 12, a community information storage unit 13, a display control unit 14, and an event participation information storage unit 15.

(User Identification Information Storage Unit 11)
If user identification information has not been generated when the user identification information storage unit 11 receives communication to a storage location from a user terminal 20 that has acquired storage location information from a tangible object (card 30) on which the storage location information (card URL) is recorded, the user identification information storage unit 11 generates user identification information by acquiring user information through the user terminal 20. The user identification information storage unit 11 stores the generated user identification information in association with tangible object information (card information).

(Community information storage unit 13)
The community information storage unit 13 stores community identification information. Specifically, the community information storage unit 13 stores user identification information in association with community identification information that identifies a community to which the user belongs among a plurality of communities.

In addition, when the community identification information is stored in association with card information (tangible information), the community information storage unit 13 may store the user identification information and the community identification information in association with each other by receiving communication from the user terminal 20 to the storage location (receiving communication from the user terminal 20 to the storage location and receiving a request from the user via the user terminal 20).

(Connection information storage unit 12)
The connection information storage unit 12 generates and stores connection information. The connection information is information indicating a connection between a first user and a second user. The connection information is information suggesting that the first user and the second user are connected on the system. The connection information storage unit 12 generates and stores connection information when the user identification information of the first user and the second user different from the first user is generated, the connection information storage unit 12 receives communication from the user terminal 20 of the first user to a storage location of the business card information of the second user, and the access information indicating that the user terminal 20 of the first user is accessing the business card information management device 10 is generated. The flow of generating connection information will be described later.

(Display Control Unit 14)
The display control unit 14 controls display on the user terminal 20 and the administrator terminal 40. Specifically, if user identification information (and business card information) has been generated when communication is received from the user terminal 20 to the storage location, the display control unit 14 causes at least a part of the business card information to be displayed on the user terminal 20. The display control unit 14 may display a part of the business card information without displaying all of the business card information input by the user, or may display all of the business card information input by the user.

The display control unit 14 may also display information linked to the community identification information, including at least a portion of the business card information, on the administrator terminal 40. When the user identification information and the community identification information are linked as shown in FIG. 8, which user belongs to which community is stored in the business card information management device 10. Since the user identification information 801 and the card information 802 are linked as shown in FIG. 6, the display control unit 14 can display the business card information (for each user) linked to the community identification information on the administrator terminal 40. In other words, the administrator (owner of the community) of the administrator terminal 40 can view information (business card information) of users who belong to the community managed by the administrator on the administrator terminal 40.

The display control unit 14 may also use the community identification information and the connection information to display on the administrator terminal 40 information about a user who has a connection with a user belonging to a community, including at least a part of the user's business card information. As shown in FIG. 8, when the user identification information and the community identification information are linked, which user belongs to which community is stored in the business card information management device 10. When the connection information 803 is generated as shown in FIG. 7, the display control unit 14 can display on the administrator terminal 40 the business card information of the user related to the user identification information linked to the community identification information and the user connected to the user (specified from the connection information). That is, the administrator of the administrator terminal 40 (owner of the community) can view information on which users belonging to the community managed by the administrator are connected to which users belonging to the community.

The display control unit 14 may also cause information linked to the community identification information and including at least a portion of the business card information of another user different from the first user to be displayed on the user terminal 20 of the first user. That is, for example, the display control unit 14 may cause the user terminal 20 (user terminal A) of user A, who is a first user belonging to a certain community, to display the business card information of another user belonging to the community. Therefore, user A can check the information of other members belonging to the same community on his or her own user terminal 20.

(Event participation information storage unit 15)
The tangible object (card 30) may be used, for example, to participate in a community event. An event is an occasion planned and managed by a person belonging to the community (including the owner). Such events include, for example, a networking event between different industries, a dinner party, a study group, and the like.

The event participation information storage unit 15 stores the user identification information and the event participation information related to participation in the community event in association with each other. The event participation information storage unit 15 may also store the user identification information and the community identification information in association with each other. For example, assume that a user A belonging to the community A logs into a web application provided by the business card information management device 10 via the user terminal 20 and expresses his/her intention to participate in the community A event (e.g., presses the "Participate in the event" button). In this case, the event participation information storage unit 15 stores the user identification information and the event participation information (information related to the expression of intention to participate in the event) in association with each other (the user identification information and the community identification information may also be stored in association with each other). This allows the business card information management system 1 to grasp the situation regarding the user's expression of intention to participate in the community A event. Therefore, in an actual event, the management of participants can be easily performed. Furthermore, when the card 30 is used as a participation certificate for the event, the participation of the participants can be confirmed smoothly.

A user who has expressed an intention to participate in an event (by pressing the "Participate in an event" button) may be able to view which users will participate in the event. A user may also be able to view which users have participated in events that the user has participated in in the past. The above has been described on the assumption that user A belongs to community A (the assumption that the user identification information of user A is linked to the community identification information of community A), but even a user who does not belong to community A may be able to participate in an event of community A. In this case, the user may be configured to be able to participate in an event of community A through a QR code (registered trademark) or URL linked to information regarding participation in an event of community A. As another example of event participation, a user may search for an event from a menu, enter a password given to him by the event organizer (community owner) on a screen displaying information about the event, and if the password is correct, a screen for participating in the event is displayed, and the user may be able to express his intention to participate in the event by pressing the "Participate" button.

(Various screen examples)
11 is a diagram showing an example of a business card information screen displayed on a user terminal. The business card information screen 900 may be a screen for the user to input and edit business card information, or may be a screen for viewing business card information.

For example, when user A, who holds a card 30 and has been issued an account (user identification information) corresponding to the card 30, logs in to the web application of the business card information management system 1, the user terminal 20 may display a screen for inputting and editing business card information on the display. In this case, the business card information screen 900 may display an edit button as shown in FIG. 11. Also, a screen for viewing business card information may be displayed on a user terminal 20 (e.g., user terminal B) other than user A who holds the card 30. In this case, the business card information screen 900 may not display the edit button as shown in FIG. 11.

The business card information screen 900 may include a basic information display area 901 and a detailed information display area 902.

The basic information display area 901 may be an area for displaying basic information from the business card information. The basic information may be the user's name, company name, job title, etc. In addition, when editing, it may be possible to upload image data of the user to the basic information display area 901, and the uploaded photo may be displayed when viewing.

The detailed information display area 902 may be an area for displaying detailed information of the business card information. The detailed information may be the user's hometown, hobbies, career/educational background, line of business/industry, business/service details, self-introduction, etc.

The business card information screen 900 may include other areas. For example, the business card information screen 900 may include areas for inputting, editing, or viewing information such as the user's contact information, such as an email address or a social networking service (SNS) account.

In addition, the business card information screen 900 may be able to upload presentation materials, etc. when editing, and may be able to display uploaded presentation materials when viewing.

Figure 12 is a diagram showing an example of a connection information screen displayed on a user terminal. The connection information screen 910 is a screen for viewing information about a user (including at least a portion of the business card information) whose connection information with a user (e.g., user A) currently logged in to the web application of the business card information management system 1 is recorded.

The connection information screen 910 may include a selection tab 911, a search field 912, a user information display area 913, and a favorites registration button 914.

In the selection tab 911, the user can select either the "Connections" tab or the "Favorites" tab as the users to be displayed in the user information display area 913. When the "Connections" tab is selected, the users to be displayed in the user information display area 913 are users who have connection information with user A recorded. When the "Favorites" tab is selected, the users to be displayed in the user information display area 913 are users who are registered as favorites. Note that by tapping on an area of each user displayed in the user information display area 913, the user may transition to a screen that displays the business card information of that user. The transition destination screen may also include an area in which notes can be entered. This allows the user to enter and store information about users they have met in the past.

In the search field 912, a keyword can be entered to narrow down the user's search results by keyword search. The search target may be, for example, all character strings contained in business card information, or may be character strings entered in the memo described above.

When the favorite registration button 914 is pressed, the corresponding user's information is displayed in the "Favorites" tab.

Figure 13 shows an example of a user list screen displayed on an administrator terminal. The user list screen 920 is a screen for viewing by the community administrator, and contains a list of users who belong to the community.

The user list screen 920 may include a search area 921, a display area 922, a community icon 923, and an event icon 924.

The community icon 923 indicates which community corresponds to the user list screen 920. The user list screen 920 in the example of FIG. 13 shows a list of users who belong to a community called "Group A."

The search area 921 may include a keyword input field in which free words can be input, a field for selecting business type/industry, a field for selecting hometown, a field for selecting hobbies, a search button, etc.

The display area 922 may include items such as "User ID," "Name," "Email," "Company name," "Position," "Number of connections," and "Links."

The "User ID" item displays the user's user ID (user identification information). The user ID is an identifier for identifying the user. The "Name" item displays the user's name. The "Email" item displays the user's email address. The "Company Name" item displays the name of the company to which the user belongs. The "Job Title" item displays the user's job title. The "Number of Connections" item displays the number of users who have recorded connection information with the user. The "Link" item includes a link button for transitioning to a screen that displays detailed information about the user (information about connected users, number of events participated in, number of matches, etc.) and a link button for transitioning to a screen that displays the user's profile (business card information).

The administrator terminal 40 may also obtain information indicating the connections between users belonging to the community from the business card information management device 10 and display it. For example, when the administrator terminal 40 receives an operation from the administrator to identify a user belonging to the community, the administrator terminal 40 may display, among the user information belonging to the community, a list of user information in which connection information with the user is recorded, and a list of user information in which connection information with the user is not recorded.

This allows community administrators to understand the state of connections between users who belong to the community.

The administrator terminal 40 may also obtain the results of analysis by AI or the like based on information indicating user attributes such as hobbies, business type, industry, hometown, job type, and job title from the business card information management device 10, and display the matching rate between users belonging to the community (a number indicating the degree of compatibility between one user and another (whether they will be a business match, etc.)). This allows the community administrator to encourage matching between users participating in the community.

Clicking on the event icon 924 may transition to a list screen of event information. The list screen of event information may display the date and time of the event in the community, the number of participants in the event, and information about the participants in the event (such as business card information).

The administrator terminal 40 may also obtain information such as the number of events each user participated in within the community and each user's behavior rate (the proportion of events participated in compared to the number of events held) from the business card information management device 10 and display it on the administrator terminal 40.

(Example of operation)
14 is a sequence diagram showing an example of a flow of generating user identification information. User identification information is information for identifying (distinguishing) a user, such as a user ID. The flow of generating user identification information is, in other words, a flow of issuing a user account for using the business card information management system 1. The user account may be, for example, an account for logging in to a web application for managing one's own business card information.

The user account issuance flow shown in Figure 14 shows an example of the communication flow when user A, who has not yet been issued an account, obtains card 30 (card A shown in Figure 1) and first reads card 30 (card A) with his or her own user terminal 20 (user terminal A).

In step S101, the user terminal 20 (user terminal A) obtains information indicating the card URL (storage location information) from the card 30 (tangible object) by short-range wireless communication with the tag 31 included in the card 30 (card A) or by reading the two-dimensional code printed on the card 30.

In step S102, the user terminal 20 communicates with the card URL. Here, the card URL contains the address of the business card information management device 10 on the Internet. This allows the user terminal 20 to communicate with the business card information management device 10. Also, the card URL is generated in advance by the business card information management device 10 so that it is different for each card 30, and is included in the card information (tangible information). This allows the business card information management device 10 to know which card 30 has been read when it receives communication with the card URL.

In step S103, the business card information management device 10 checks whether a user account corresponding to the read card 30 has been issued (i.e., whether user identification information has already been generated). Details of the processing of the business card information management device 10 will be described later.

In step S104, if the business card information management device 10 determines that a user account has not been issued, it sends a request to display an account issuance screen to the user terminal 20.

In step S105, the user terminal 20 displays an account issuance screen. The content displayed on the account issuance screen may be input fields for inputting information required for logging in to the web application of the business card information management system 1, such as an email address and a password. In addition, the account issuance screen may display information encouraging registration in cooperation with an external application (e.g., LINE (registered trademark), Facebook (registered trademark), etc.) as an alternative method of registering an email address, password, etc.

In step S106, the user terminal 20 transmits the user information (email address, password, account information for external services, etc.) input by User A to the business card information management device 10.

In step S107, the user identification information storage unit 11 of the business card information management device 10 stores the received user information in the storage unit of the business card information management device 10. As a result, the business card information management device 10 issues an account for user A. That is, the user identification information storage unit 11 generates user identification information for user A (for example, "U001" of "User ID" in FIG. 5 is generated). In this way, when user identification information is not generated when communication to the storage location is received from the user terminal 20 (user terminal A) that has acquired storage location information from the tangible object (card 30) in which the storage location information (card URL) is recorded, the user identification information storage unit 11 generates user identification information by acquiring user information through the user terminal 20 (user terminal A) (by acquiring user information (email address, password, account information for external services, etc.) entered by user A into user terminal A). After the account is issued, the user may be able to log in to a WEB application and enter business card information.

Then, in step S108, the user identification information storage unit 11 stores the card information (tangible information) of card A in association with the user identification information issued in step S107. That is, values are written into the data table shown in FIG. 6 (for example, if the card ID of card A is C001, the user ID of user A: U001 is linked to the card ID (C001)). Also, if the card information includes community identification information, the community information storage unit 13 stores the user identification information in association with the community identification information. That is, values are written into the data table shown in FIG. 8 (for example, the user ID of user A: U001 is linked to the community ID: G001).

Figure 15 is a sequence diagram showing an example of a business card information display flow. The business card information display flow is a communication flow when the card 30 of a user who meets face-to-face during the exchange of business cards, etc. is read by the user terminal 20. The business card information display flow shown in Figure 15 shows the communication flow when user A, who has issued an account and has already entered his/her business card information on card A, meets user B and reads card A with user terminal 20 (user terminal B).

In step S201, the user terminal 20 (user terminal B) obtains information indicating the card URL from the card 30 by short-range wireless communication with the tag 31 included in the card 30 (card A) or by reading the two-dimensional code printed on the card 30.

In step S202, the user terminal 20 (user terminal B) communicates with the card URL. Here, the card URL includes the address of the business card information management device 10 on the Internet. This allows the user terminal 20 to communicate with the business card information management device 10.

In step S203, the business card information management device 10 transmits to the user terminal 20 (user terminal B) a display request for a business card information screen including business card information linked to the card information corresponding to the card URL of the received card A. Details of the processing of the business card information management device 10 will be described later.

In step S204, the user terminal 20 displays the business card information screen (see FIG. 11).

Figure 16 is a sequence diagram showing an example of a connection information generation flow. The connection information generation flow is a communication flow when user B, who is logged in to the web application of the business card information management system 1, reads the card 30 of a user (user A) who met during a business card exchange or the like, with his/her own user terminal 20 (user terminal B). The connection information generation flow shown in Figure 16 shows a communication flow when user B, who is logged in to the web application, reads the card 30 (card A) of user A who met with him/her with his/her user terminal 20 (user terminal B). Note that it is assumed that user A and user B's user identification information (for example, "U002" in the "user ID" shown in Figure 5 is user B's account) has already been generated for each of users A and B in the user account issuance flow shown in Figure 14.

In step S301, the user terminal 20 (user terminal B) obtains information indicating the card URL of card A from the card 30 by short-range wireless communication with the tag 31 included in the card 30 (card A) or by reading the two-dimensional code printed on the card 30 (card A).

In step S302, the user terminal 20 communicates with the card URL. Here, the card URL includes the address of the business card information management device 10 on the Internet. This allows the user terminal 20 to communicate with the business card information management device 10.

In step S303, the connection information storage unit 12 of the business card information management device 10 records connection information between the account (user identification information: "U002") of user B corresponding to the communication source user terminal 20 (user terminal B) and the account (user identification information: "U001") linked to the card 30 (card A). That is, values are written into the data table shown in FIG. 7 (for example, connection ID: X001, first user ID: U001, second user ID: U002).

In this way, the user identification information of the first user (user B) and the second user (user A) are generated, and further, when the business card information management device 10 receives communication from the user terminal 20 (user terminal B) of the first user to the storage location of the business card information of the second user (user A), and further, when access information is generated indicating that the user terminal 20 (user terminal B) of the first user is accessing the business card information management device 10 (i.e., when user B is logging in to an application provided by the business card information management device 10 from user terminal B), the connection information storage unit 12 generates and stores connection information indicating the connection between the first user (user B) and the second user (user A).

Returning to FIG. 16, in step S304, the business card information management device 10 transmits to the user terminal 20 a display request for a business card information screen including business card information linked to the card information corresponding to the card URL of the received card A. Details of the processing of the business card information management device 10 will be described later.

In step S305, the user terminal 20 displays the business card information screen (see FIG. 11).

In the connection information generation flow shown in FIG. 16, the flow in which user A and user B are connected when user B reads card A with user terminal B while already logged in to the web application of the business card information management system 1 has been described. However, another example will be described. As another example, assume that user B reads card A with user terminal B when not logged in to the web application of the business card information management system 1. Then, assume that user B logs in to the web application of the business card information management system 1 after a while. In this case as well, the connection information storage unit 12 generates and stores connection information indicating the connection between the first user (user B) and the second user (user A). That is, the connection information storage unit 12 may generate connection information using cache data (cache when card A is read with user terminal B) stored in user terminal B.

Figure 17 is a sequence diagram showing an example of a flow for linking community identification information to user identification information. The flow for linking community identification information to user identification information shown in Figure 17 can be said to be a flow for switching to card C when, for example, the operator of the business card information management system (or the owner of the community) hands over another card C linked to community identification information to user B, assuming that the card information (tangible information) of card B held by user B is not linked to community identification information. This is the communication flow when user B obtains a new card 30 (card C) for registering in the community and reads card C with his/her user terminal 20 (user terminal B). It is assumed that user B has logged in to the Web application of the business card information management system 1 using the user ID used when user B's account was issued.

In step S401, the user terminal 20 (user terminal B) obtains information indicating the card URL of card C from the card 30 by short-range wireless communication with the tag 31 included in the card 30 (card C) or by reading the two-dimensional code printed on the card 30.

In step S402, the user terminal 20 communicates with the card URL. Here, the card URL includes the internet address of the business card information management device 10. This allows the user terminal 20 to communicate with the business card information management device 10.

In step S403, the business card information management device 10 transmits to the user terminal 20 a display request for a community registration screen for confirming the intention to register in the community, which is linked to the card information corresponding to the card URL of the received card C. Details of the processing of the business card information management device 10 will be described later.

In step S404, the user terminal 20 (user terminal B) displays a community registration screen on the display. The community registration screen may include a button for selecting whether or not to register in the community (a button for linking the user ID of user B with the community identification information).

In step S405, when the user terminal 20 receives a selection from user B to join the community (e.g., pressing the "Yes" button), the user terminal 20 sends a community registration request to the business card information management device 10.

In step S406, the community information storage unit 13 of the business card information management device 10 records the registration to the community related to the community identification information linked to the card 30 (card C). Specifically, the community information storage unit 13 adds an entry of the user B who is logged in to the Web application to the data table shown in FIG. 8 (for example, user ID: U002 and community ID: G002 are written to the data table shown in FIG. 8). As described above, when the community identification information is stored linked to the tangible information (card information) (when the community identification information is linked to the card C), the community information storage unit 13 may store the user identification information and the community identification information linked to each other by receiving communication from the user terminal 20 to the storage location (by the user terminal B reading the card C and the user B performing a predetermined operation on the user terminal B (for example, pressing a button to indicate the intention to register the community)). This allows the user to smoothly switch to the card linked to the community identification information halfway through, even if the user is using a card 30 that is not linked to the community identification information at first.

Note that the processing when user B is not logged in to the web application of the business card information management system 1 is optional. For example, instead of the community registration screen in step S404, a login screen for the web application may be displayed, and user B may log in from the login screen using the account issued for card B, thereby linking the user identification information with the community identification information (in this case, when user B logs in from the login screen, the process proceeds to S404, and the same flow is followed from S405 onwards). As another example, a "new account creation screen" corresponding to card C may be displayed, and user B may create a new account for card C (generate user identification information). When the account is created, the community identification information linked to card C may be automatically linked to the issued account (user identification information).

As another flow for linking the community identification information to the user identification information, the community information storage unit 13 may link the user identification information to the community identification information and store them using a URL or QR code (registered trademark) linked to the community identification information. That is, without using a new card C (card ID: C003, community ID: G002) as shown in the example of FIG. 17, the community identification information may be linked to the user identification information using a URL linked to the community identification information (community ID: G002).

(Flow when user terminal A communicates with its own card A)
Fig. 18 is a flowchart showing an example of the process flow of the business card information management device. The business card information management device 10 realizes the various communication flows described above by the process flow shown below. This flowchart starts from a state in which the business card information management device 10 is waiting for communication from the user terminal 20. The process shown in Fig. 10 shows the communication flow when user A communicates with card A using user terminal A.

In step S501, the business card information management device 10 receives communication from user A's user terminal 20 (user terminal A) to the business card information storage location (card URL) of card A.

In step S502, the business card information management device 10 determines whether an account (user identification information) linked to the storage location (card URL) of the business card information of card A has been issued. Specifically, the business card information management device 10 makes this determination based on whether the card information of card A is linked to the user identification information of user A.

When the business card information management device 10 determines that the account has not been issued (step S502: NO), in step S503, the user identification information storage unit 11 sends a display request for an account issuance screen to the user terminal 20 (corresponding to step S104 in FIG. 14).

When the business card information management device 10 determines that an account has been issued (step S502: YES), in step S506, the display control unit 14 sends a display request to the user terminal 20 (user terminal A) for a business card information screen including the business card information corresponding to the card URL. As a result, user A's own business card information is displayed on user terminal A, and user A can view and edit it. Note that before step S506, there may be a step of determining whether user A is logged in to the web application from user terminal A. Then, the type of business card information screen displayed on user terminal A may differ depending on whether user A is logged in or not.

(Flow when user terminal B communicates with card A)
Fig. 19 is a flowchart showing another example of the process flow of the business card information management device. The business card information management device 10 realizes the various communication flows described above by the process flow shown below. This flowchart also starts from a state in which the business card information management device 10 waits for communication from the user terminal 20. The process shown in Fig. 19 shows a communication flow when user B communicates with card A of user A using user terminal B. The process shown in Fig. 19 also shows a flow when user A and user B are connected. It is assumed that user A and user B have previously issued accounts (user identification information) using card A and card B, respectively.

In step S501, the business card information management device 10 receives communication from user B's user terminal 20 (user terminal B) to the business card information storage location (card URL) of card A.

In step S502, the business card information management device 10 determines whether or not the account (user identification information) of user A linked to the storage location (card URL) of the business card information of card A has been issued.

If the business card information management device 10 determines that the account has not been issued (step S502: NO), the process proceeds to step S503, but the processing is the same as that described in FIG. 18.

When the business card information management device 10 determines that an account for user A has been issued (step S502: YES), in step S504 it determines whether the user terminal 20 (user terminal B) that is the communication source is logged in to a web application. Specifically, it determines whether user B is logged in to the web application based on whether login information for user B (access information indicating that user terminal B is accessing the business card information management device 10) has been generated in the business card information management device 10.

When the business card information management device 10 determines that user B is logged in to the system (step S504: YES), in step S505, the connection information storage unit 12 records connection information between the account corresponding to the communication source user terminal 20 (user terminal B) (i.e., user B's account) and the account linked to the storage location information (card URL) of the business card information of card A (i.e., user A's account). Specifically, the connection information storage unit 12 adds an entry to the data table shown in FIG. 7.

Returning to FIG. 19, if the business card information management device 10 determines that the user is not logged in (step S504: NO), it skips the processing of step S505.

In step S506, the display control unit 14 sends a display request to the user terminal 20 (user terminal B) for a business card information screen including the business card information corresponding to the card URL of card A. As a result, the business card information of user A is displayed on user terminal B of user B.

In addition, in step S504 described above, if the user terminal 20 (user terminal A) corresponding to the read card URL is currently logged in, the business card information management device 10 may send to the user terminal 20 (user terminal A) a display request for a business card information screen including the business card information of user B corresponding to the user terminal 20 (user terminal B) that performed the reading. This allows the user terminal 20 (user terminal A) that read the digital business card and the user terminal 20 (user terminal B) that read the digital business card to each display each other's business card information.

(Action and Effect)
Most conventional digital business card systems are systems that only digitally transmit one's own business card information to the other party, and there was no digital business card system that contributes to the formation of a community. The business card information management system 100 according to the present embodiment includes a user identification information storage unit 11, a community information storage unit 13, and a display control unit 14. Since the community to which a user belongs is linked to the user's digital business card, the community owner (administrator) can more effectively utilize the business card information of users (community participants) within his or her own community.

Furthermore, when the community identification information is stored in association with tangible object information, the community information storage unit 13 may store the user identification information in association with the community identification information by receiving communication from the user terminal 20 to the storage location. As a result, as described in FIG. 17, even if a card 30 that is not associated with community identification information is used at first, it is possible to smoothly switch to a new card associated with community identification information midway through.

Furthermore, the display control unit 14 may cause information linked to the community identification information and including at least a portion of the business card information to be displayed on an administrator terminal 40 used to manage the community. This allows the community owner (administrator) to grasp the business card information of users belonging to his/her community on his/her own terminal. This allows the community owner (administrator) to promote appropriate matching between users belonging to his/her community, thus contributing to the formation of a high-quality community.

Furthermore, the business card information management system 100 may be equipped with a connection information storage unit 12. This allows easy recording of users with whom the card 30 has been communicated once. This allows easy recall of information about users that the user has met in the past.

Furthermore, the display control unit 14 may use the community identification information and the connection information to display information about users who have connections with users who belong to the community, including at least a portion of the business card information, on an administrator terminal 40 used to manage the community. This allows the community owner to know which users participating in the community he or she manages are connected to (are acquainted with each other). This can more effectively promote appropriate matching between users belonging to his or her community.

Furthermore, the display control unit 14 may cause information linked to the community identification information and including at least a portion of the business card information of a user different from the first user to be displayed on the user terminal 20 of the first user. This allows not only the community owner but also the participants of the community to grasp the business card information of other participants in the same community.

The business card information management system 100 may further include an event participation information storage unit 15. This allows the business card information management system 100 to determine whether or not an event will be attended, and to settle the participation fee, etc.

Furthermore, digital business cards can also be used to confirm participation in community events. For example, as a first pattern, participation in a community event can be accepted by reading the event organizer's digital business card with the user's (event participant's) user terminal.

In the second pattern, the event organizer can read the user's (event participant's) digital business card on the event organizer's user terminal, thereby obtaining the user's user information and business card information, and thereby accepting participation in the community event.

(Modification)
The tangible object according to the present embodiment may not be a card-shaped object, and may be, for example, a key holder including an NFC tag. A user terminal may also function as a tangible object. For example, a dedicated application may be installed in the user terminal to have the function of the tangible object according to the present embodiment. For example, a user terminal functioning as a tangible object may have a function of transmitting a card URL to another user terminal 20 by short-range wireless communication with the other user terminal 20.

The above describes the embodiments with reference to the drawings, but these are merely examples of the present invention, and various configurations other than those described above can also be adopted.

Each user may have multiple cards 30 as their own digital business cards. For example, if a user belongs to multiple communities, the user may have cards 30 linked to each community, or may have cards 30 that are not linked to any community.

In the embodiment, the business card information management device 10 has been described as a server that provides a web application for managing users' business card information as a service, but it may also be a server that provides a mobile application (smartphone application) as a service.

When a user belongs to two or more communities, two or more community identification information may be linked to one user identification information. For example, when a user already owns a card linked to a first community identification information of a first community and wants to switch to a card linked to a second community identification information of a second community, the user identification information may be linked to the first community identification information and the second community identification information by performing a process similar to the flow described in FIG. 17.

Note that the sequence diagrams (FIGS. 14, 15, 16, 17) and flow charts (FIGS. 18, 19) according to this embodiment are merely one embodiment. Within the scope of the present invention, there may be processes other than those described in each diagram, some of the processes described in each diagram may be omitted, and the order of the processes may be changed.

Although the embodiment of the present invention has been described above, the embodiment disclosed here is illustrative in all respects and should not be considered as limiting. The scope of the present invention is indicated by the claims rather than the above description, and is intended to include the meaning equivalent to the claims and all modifications within the scope.
