Description

[Technical Field]

[0001] The present invention relates to a business card management system and a business card management program for managing information related to business cards. [Background technology]

[0002] There is known a business card management system that manages information about business cards. The business card management system disclosed in JP 2021-026630 A (Patent Document 1) includes a scanner (7a, 7b) that scans business cards and a business card processing unit (107) that extracts business card information from the scanned business card image and registers the business card information in a business card database. The business card processing unit (107) compares the extracted business card information with the business card information in the business card database, and if there is business card information with the same organization name, name, and email address (S102, S103), and if there is a difference between the business card information, it updates the business card information in the business card database with the newly extracted business card information and registers it (S104). This update is basically performed when the scan date and time of the newly extracted business card information is newer than the scan date and time of the business card information in the business card database. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent Publication No. 2021-026630 Summary of the Invention [Problem to be solved by the invention]

[0004] In a business card management system that scans business cards, the actual date on which a user exchanged business cards may differ from the date on which the cards were scanned. Patent Document 1, in response to this issue, discloses a method of requiring the user to reconfirm the information each time the card is updated. However, such reconfirmation places a heavy burden on the user when business cards are exchanged frequently or when a large number of business cards are registered at one time. Therefore, with a method that requires the user to reconfirm the information each time the card is updated, the user is likely to neglect to accurately confirm the information, which can lead to the registration of incorrect business card information based on a date different from the actual date on which the cards were exchanged.

[0005] Therefore, it is desirable to realize a business card management system and a business card management program that can increase the likelihood that the day on which business cards were actually exchanged or a day close to that day will be registered as the business card exchange date. [Means for solving the problem]

[0006] A business card management system according to the present disclosure includes a business card database in which business card information for each of a plurality of business cards is stored, a processing server connected to the business card database, and an input terminal communicably connected to the processing server and configured to accept input of the business card information for one or more of the business cards by a plurality of users, wherein the business card information includes business card address information indicating an address written on the business card, and the processing server is configured to execute a business card registration process in cooperation with the input terminal to register the business card information input by each of the plurality of users in the business card database, wherein one of the plurality of users who input the business card information via the input terminal is a target user, the date on which the business card information was input by the target user is an input date, and the business card for which the business card information was input by the target user within a set period is a target business card, and The processing server executes a target area acquisition process to acquire target area information indicating a target area which is at least one of an input area where the target user inputted the business card information and a responsible area which is an area for which the target user is responsible, executes a non-target area proportion calculation process to calculate a non-target area business card proportion which is the proportion of the number of target business cards which have the business card address information of an area other than the target area among the target input number, and if the non-target area business card proportion is equal to or less than a judgment threshold, executes a business card exchange date registration process to register the input date as the business card exchange date of the target business card in the business card database, and if the non-target area business card proportion is greater than the judgment threshold, executes a business card exchange date pending process to register the business card exchange date of the target business card as unknown in the business card database or to leave the business card exchange date of the target business card unregistered.

[0007] A business card management program according to the present disclosure is a business card management system including a business card database storing business card information for each of a plurality of business cards, a processing server connected to the business card database, and an input terminal communicably connected to the processing server and configured to accept input of the business card information for one or more of the business cards by a plurality of users. The business card management program causes a computer to realize the business card management function of the processing server, wherein the business card information includes business card address information indicating an address written on the business card, one of the plurality of users who input the business card information via the input terminal is a target user, the date on which the business card information was input by the target user is an input date, the business card for which the business card information was input by the target user within a set period is a target business card, and the number of the target business cards is a target input number. A business card registration process is executed to register the business card information in the business card database, a target area acquisition process is executed to acquire target area information indicating a target area which is at least one of an input area where the target user inputted the business card information and a responsible area which is an area for which the target user is responsible, a non-target area proportion calculation process is executed to calculate a non-target area business card proportion, which is the proportion of the number of target business cards which have the business card address information of an area other than the target area to the number of target input cards, and if the non-target area business card proportion is equal to or less than a judgment threshold, a business card exchange date registration process is executed to register the input date as the business card exchange date of the target business card in the business card database, and if the non-target area business card proportion is greater than the judgment threshold, a business card exchange date reservation process is executed to register the business card exchange date of the target business card as unknown in the business card database, or to leave the business card exchange date of the target business card unregistered.

[0008] According to this configuration, when there is a large amount of business card information for business cards that have business card address information outside the target region, the registration of such business card information may not be registration of business card information that was made on the actual business card exchange date, and the business card exchange date can be set to unknown or unregistered. Therefore, when the target user does not input business card information on the day the business cards were exchanged, but inputs business card information related to business cards exchanged in the past, and the proportion of target business cards that have business card address information outside the target region, which is at least one of the input region and the area of ​​responsibility, becomes high, the input date of such business card information may be set to unknown or unregistered, and the business card exchange date can be set to unknown or unregistered. This increases the likelihood that the actual business card exchange date or a date close to it will be registered as the business card exchange date. [Brief explanation of the drawings]

Each input terminal 20, which is a portable information terminal, includes an imaging device 23 that can capture an image of at least one business card 11.

[0018] The processing server 15 and the plurality of input terminals 20 are connected to each other so as to be able to communicate with each other via a network 25. The network 25 may be both a wired and a wireless network. In this embodiment, a relay device (not shown) and the processing server 15 are connected via a wired network, and the input terminals 20 and the relay device are connected via a wireless network. However, the processing server 15 and the input terminals 20 may be connected via a wired network, or the processing server 15 and the input terminals 20 may be directly connected via a wireless network.

[0019] The business card management system 10 includes a business card database 31. The business card database 31 stores business card information 31d for each of a plurality of business cards 11. The processing server 15 is connected to the business card database 31. In this embodiment, one piece of business card information 31d is registered in the business card database 31 for one business card 11.

[0020] 2 is a diagram showing an example of a screen displaying multiple pieces of business card information 31d registered in the business card database 31. Examples of the business card information 31d include a name 17a, an affiliation 17b such as a company name or department name, a job title, an address, contact information such as an email address 17c or a telephone number, an exchange user who is a user 12 with whom the business card 11 was exchanged, and a captured image of the business card 11. The business card information 31d is associated with a business card ID. In this embodiment, the business card ID is a number unique to each of the multiple business cards 11.

[0021] The screen shown in FIG. 2 displays the results of a search narrowed down by main item A1 for all business card information 31d registered in the business card database 31. Main item A1 is an item for identifying whether or not the person listed on multiple business cards 11 is the same person. Examples of main item A1 include name 17a, affiliation 17b, email address 17c, and an identification number for identifying the same person. On the screen shown in FIG. 2, multiple pieces of business card information 31d with the same main item A1 are arranged in descending order of input date D1. In the illustrated example, main item A1 is name 17a and affiliation 17b. In this embodiment, affiliation 17b is a company name, but it may also be a company name and department name, or the name of a local government, region, etc.

[0022] The business card information 31d includes business card address information 17f indicating the address written on the business card 11. If there are multiple addresses written on the business card 11, the address with the highest predetermined priority, such as the topmost or rightmost address, is registered as the business card address information 17f in the business card database 31. Examples of the business card address information 17f include the address of the user 12's workplace, the address of the head of the group to which the user 12 belongs, the address of the user 12's home, etc.

[0023] Returning to FIG. 1, the business card management system 10 includes a location database 32. The location database 32 stores location information 32d indicating the location of the input terminal 20. The processing server 15 is connected to the location database 32. Examples of the location information 32d include coordinates such as the place name, address, latitude, longitude, and altitude of the location where the input terminal 20 is installed, the location of the input terminal 20, which is a personal digital assistant (PDA), acquired by a location information service or the like, the location of the input terminal 20 by day, and the location of the input terminal 20 by date and time.

[0024] The business card management system 10 includes a map database 33. The map database 33 stores map information 33d. The processing server 15 is connected to the map database 33. Examples of the map information 33d include coordinates such as latitude, longitude, and altitude, topographical features such as rivers, mountains, and coastlines, and areas such as national borders and administrative districts.

[0025] The business card management system 10 includes a schedule database 34. The schedule database 34 stores meeting information 34d for each of a plurality of users 12. The processing server 15 is connected to the schedule database 34. Here, a meeting is a general term for a situation in which a business card 11 is used, in other words, a situation in which people meet, and includes various situations such as business trips.

[0026] Examples of the meeting information 34d include the name of the meeting, the planned participants, the planned number of participants, the planned date and time, the meeting method such as a visit or a web meeting, business partner information such as the business partner's name and business partner's company information, the location, the actual participants, the actual number of participants, and the actual date and time of the meeting. In this embodiment, the meeting information 34d includes specific information that can identify one or more users 12 who will be attending each meeting. The meeting information 34d includes specific information that can identify all users 12 who will be attending each meeting or all users 12 who have attended each meeting. Examples of the specific information include user names, account names, email addresses, etc.

[0027] 3 is a diagram showing an example of a screen displaying meeting information 34d registered in the schedule database 34. One of the multiple users 12 who input business card information 31d via the input terminal 20 is designated as the target user 12a. The date on which the business card information 31d was input by the target user 12a is designated as input date D1. FIG. 3 shows an example of meeting information 34d in the case where the target user 12a participated in a meeting with other users 12 on input date D1.

[0028] 1, the business card management system 10 includes a user database 35. The user database 35 stores attribute information 35d for each of a plurality of users 12. The processing server 15 is connected to the user database 35.

[0029] 4 is a diagram showing an example of a screen showing details of attribute information 35d of user 12. Examples of the attribute information 35d include user name, affiliation such as company name or department name, job title, address, contact information such as email address or telephone number, and a captured image of the business card of user 12.

[0030] The attribute information 35d includes user address information 12f indicating the addresses of each of the multiple users 12. Examples of the user address information 12f include the address listed on the business card 11 of the user 12, the address of the workplace of the user 12, the address of the representative of the group to which the user 12 belongs, the address of the home of the user 12, etc.

[0031] 5 and 6 are diagrams showing an example of attribute information 35d of a user 12, showing the area for which the user 12 is responsible. The attribute information 35d includes user area information 12h indicating the area for which each of multiple users 12 is responsible. In this embodiment, the area for which the user 12 is responsible is an area for sales, but it may also be an area for maintenance work, an area for procurement work, an area for security work, etc. In this embodiment, the area for which the user 12 is responsible is expressed as an administrative district such as a state, prefecture, or city, but it may also be expressed as a region, metropolitan area, a range previously set in the map database 33, etc.

[0032] The attribute information 35d of the user 12 includes information on an individual area B1, which is an area that the user 12 is personally responsible for. In the example shown in FIG. 5, areas that one user 12 is responsible for are shown as shaded areas. The black areas are the business card acquisition information C1 of the user 12. In the example shown, the business card acquisition information C1 is the area where the largest number of business cards 11 were registered by the user 12 in a certain period of time in the past. However, the business card acquisition information C1 may also be the ratio of the number of business cards 11 registered by the user 12 in each region in the certain period of time in the past, the number of registered business cards 11 in each region, the number of input business cards 11 in each region, etc. In this embodiment, information on the individual area B1 is used as the user area information 12h, but information on the group area B2, which will be described later, may also be used.

[0033] The attribute information 35d of the user 12 includes information on a group assigned region B2, which is the region assigned to the group to which the user 12 belongs. In the example shown in Fig. 6, the group assigned region B2 of the group to which the user 12 belongs is shown as a shaded region. The black region is the group's business card acquisition information C2. In the example shown, the business card acquisition information C2 is the region with the largest number of business cards 11 registered by the group in a certain period of the past, but it may also be the ratio by region of the number of business cards 11 registered by the group to which the user 12 belongs in a certain period of the past, the number of registered business cards 11 by region, the number of input business cards 11 by region, etc.

[0034] Returning to FIG. 1 , each of the multiple users 12 inputs the business card information 31d of the business card 11 into the input terminal 20 on the day they exchanged the business card 11. The input of the business card information 31d by the users 12 into the input terminal 20 is performed according to a rule that the business card information 31d of the business card 11 must be input within a set input period that is set starting from the day the business cards 11 were exchanged. This set input period is set, for example, for the current day, 24 hours, 48 ​​hours, etc. In this embodiment, this set input period is for the current day, and each of the multiple users 12 is prohibited from inputting the business card information 31d of the business card 11 into the input terminal 20 on a day after the day the business cards 11 were exchanged.

[0035] The processing server 15 is configured to cooperate with multiple input terminals 20 to register business card information 31d in the business card database 31. As shown in FIG. 2, in this embodiment, when registering the business card information 31d, the input date and time of the business card information 31d by each input terminal 20 of multiple users 12 are registered in the business card database 31 as part of the business card information 31d. The input date and time of this business card information 31d may be only the input date D1, or may be the input date D1 and the input time. The input date and time of the business card information 31d may be acquired by the input terminal 20 and sent to the processing server 15, and the date and time of reception by the processing server 15 may be used as the input date and time of the business card information 31d. The screen shown in FIG. 2 is a screen displayed on the output device 21. In this embodiment, the screen shown in FIG. 2 is a screen for managing the business card database 31.

[0036] Fig. 7 shows an example of a search screen for multiple pieces of business card information 31d registered in the business card database 31. The screen shown in Fig. 7 is a search screen displayed on the output device 21. A search button that allows for a refined search is displayed in a first area E1 of the search screen. The first area E1 of the search screen is configured to allow for a refined search by the above-mentioned main item A1, attribute information 35d, map information 33d, affiliation of the user 12, name of the user 12, etc.

[0037] The search results are displayed in the second area E2 of the search screen. The second area E2 of the search screen is configured to be able to hide business card information 31d for which the business card exchange date Da is unknown, unregistered, etc. In this embodiment, the second area E2 of the search screen is configured to be able to display only the business card information 31d with the most recent business card exchange date Da among multiple pieces of business card information 31d with the same main item A1. This prevents multiple pieces of business card information 31d of the same person from being displayed on the screen and interfering with the search. Furthermore, displaying business card information 31d with the most recent business card exchange date Da can be prioritized over displaying business card information 31d with the most recent input date D1.

[0038] 8 is a diagram showing an example of a screen displaying one piece of business card information 31d registered in the business card database 31. The business card information 31d is input by capturing an image of the business card 11 using the input terminal 20. The input terminal 20 or the processing server 15 performs optical character recognition on the captured image 11p of the business card 11 to acquire character information 11s of the business card 11 as business card information 31d to be registered in the business card database 31. In this embodiment, in the business card registration process S11 described below, the captured image 11p of the business card 11 is registered in the business card database 31 as part of the business card information 31d. The screen shown in FIG. 8 is a screen displayed on the output device 21.

[0039] In this embodiment, when registering the business card information 31d, the location of the input terminal 20 is registered in the business card database 31 as part of the business card information 31d. Examples of the location of the input terminal 20 include a location registered in advance for each input terminal 20 in the location database 32, a location acquired or estimated by a location information service or the like for the input terminal 20 which is a personal digital assistant (PDA), a location acquired from a captured image 11p having location information at the time of shooting, etc. The location of the input terminal 20 may be represented by coordinates such as latitude, longitude, and altitude, or may be represented by an address, administrative district, metropolitan area, region, etc.

[0040] 9 is a diagram showing an example of processing that the business card management program causes the processing server 15 to execute. The processing server 15 is configured to execute business card registration processing S11 in which business card information 31d input by each of a plurality of users 12 is registered in the business card database 31 in cooperation with the input terminal 20. In this embodiment, the processing server 15 executes the business card registration processing S11 every time business card information 31d input by a user 12 is received from the input terminal 20.

[0041] In the business card registration process S11, the processing server 15 registers the location of the input terminal 20 together with the business card information 31d input by each of the multiple users 12 in the business card database 31. In the business card registration process S11, the processing server 15 registers the input date D1 together with the business card information 31d input by each of the multiple users 12 in the business card database 31.

[0042] If the input terminal 20 is a personal digital assistant (PDA) such as a scanner, the location of the input terminal 20 is acquired by the processing server 15 from, for example, a location information service or the captured image 11p. If the input terminal 20 is a terminal other than a personal digital assistant such as a scanner, the location of the input terminal 20 is acquired by the processing server 15 from, for example, location information 32d in the location database 32.

[0043] The processing server 15 executes the business card exchange date registration process S17 or the business card exchange date reservation process S18. The business card exchange date registration process S17 is a process of registering the input date D1 as the business card exchange date Da of the target business card 11a in the business card database 31. The business card exchange date reservation process S18 is a process of registering the business card exchange date Da of the target business card 11a as unknown in the business card database 31, or of setting the business card exchange date Da of the target business card 11a as unregistered.

[0044] Here, the business cards 11 whose business card information 31d has been input by the target user 12a within the set period T1 are defined as target business cards 11a. The number of target business cards 11a is defined as the target input number Na. Examples of the set period T1 include one hour, six hours, one day, two days, a time that differs for each user 12, a time that differs depending on the input time, etc. In this embodiment, the set period T1 is a period that is set in advance.

[0045] The processing server 15 executes a minimum number determination process S12 to determine whether the target input number Na is equal to or less than the minimum number Nmin. If the target input number Na is less than the minimum number Nmin, the processing server 15 does not execute the outside-target-area proportion calculation process S15 described below, and registers the input date D1 as the business card exchange date Da of the target business card 11a in the business card database 31. Examples of the minimum number Nmin include a number equal to or greater than 2, a number equal to or greater than 5, a number equal to or greater than 10, a preset value, a value calculated each time the minimum number determination process S12 is executed, etc.

[0046] Here, the average number of registered cards Nv is the average number of business cards 11 for which business card information 31d has been registered in the past per set period T1 for each of the multiple users 12. The calculation of the average number of registered cards Nv may use only the set period T1 in which the business card information 31d was registered. The average number of registered cards Nv may also be the average number of business cards 11 for which the business card exchange date registration process S17 has been executed. For example, the calculation of the average number of registered cards Nv may exclude the number of business cards 11 for which the business card exchange date reservation process S18 has been executed.

[0047] In this embodiment, the minimum number Nmin is set for each user 12 based on the average number of registered sheets Nv. The minimum number Nmin may be the average number of registered sheets Nv or a value obtained by multiplying the average number of registered sheets Nv by a predetermined coefficient, but the minimum number Nmin is not set to a number less than 2. If the average number of registered sheets Nv is less than the lower limit value Nvmin, the minimum number Nmin may be the lower limit value Nvmin. Examples of the lower limit value Nvmin include a number equal to or greater than 2, a number equal to or greater than 5, a number equal to or greater than 10, etc.

[0048] The minimum number Nmin may be a value obtained by adding a predetermined coefficient K1 to the average registered number Nv. Examples of the coefficient K1 include a number equal to or greater than 1 and less than 9, a number equal to or greater than 9, or a number equal to or greater than 10.

[0049] If the number of target input sheets Na is equal to or greater than the minimum number Nmin, the processing server 15 executes attended meeting determination process S13 to determine whether there are any meetings attended by the target user 12a on the input date D1. The processing server 15 executes target area acquisition process S14 to acquire target area information indicating a "target area H." The target area H is at least one of an input area H1, which is the area where the target user 12a inputted the business card information 31d, and a responsible area H2, which is the area that the target user 12a is responsible for.

[0050] If there is a meeting attended by the target user 12a on the input date D1, the processing server 15 executes a target area acquisition process S14. If there is a meeting attended by the target user 12a on the input date D1, the processing server 15 executes a non-target area proportion calculation process S15. In this embodiment, if the meeting information 34d of the meeting attended by the target user 12a on the input date D1 can be acquired from the schedule database 34, it is determined that there is a meeting attended by the target user 12a on the input date D1.

[0051] If there is no meeting that the target user 12a attended on the input date D1, the processing server 15 executes the business card exchange date reservation process S18. In this embodiment, if the meeting information 34d of the meeting that the target user 12a attended on the input date D1 cannot be acquired from the schedule database 34, it is determined that there is no meeting that the target user 12a attended on the input date D1.

[0052] In this way, for example, on a day when the target user 12a does not attend a meeting, it is possible to prevent the business card exchange date registration process S17 from being executed for a large number of business cards 11. In addition, in such a case, for example, by executing the attention call process S19 described later, it is possible to prompt the target user 12a to input the meeting information 34d corresponding to the target business card 11a.

[0053] The processing server 15 executes a target area acquisition process S14 to acquire target area information indicating a target area H, which is at least one of an input area H1, which is the area where the target user 12a inputted business card information 31d, and a responsible area H2, which is the area for which the target user 12a is responsible.

[0054] 10 is a diagram showing an example of the target area acquisition process S14. The processing server 15 derives a responsible area H2, which is an area for which the target user 12a is responsible (S21). In this embodiment, the processing server 15 sets the area indicated in the user responsible area information 12h as the responsible area H2 in the target area acquisition process S14. The processing server 15 acquires the user responsible area information 12h of the target user 12a from the attribute information 35d stored in the user database 35.

[0055] The processing server 15 determines whether the location of the input terminal 20 is within the coverage area H2 (S22). In this embodiment, the location of the input terminal 20 is registered in the business card database 31 together with the business card information 31d as described above, but the location of the input terminal 20 may be acquired from the location database 32 in which the location information 32d is recorded each time the target area acquisition process S14 is performed.

[0056] The processing server 15 derives an input area H1, which is the area where the target user 12a input the business card information 31d (S23). In this embodiment, if the location of the input terminal 20 is not within the area H2, the input area H1 is derived.

[0057] Here, the area set based on the location of the input terminal 20 into which the business card information 31d of the target business card 11a was input is referred to as the target terminal area H1a. The processing server 15 sets the target terminal area H1a as the input area H1. Examples of the target terminal area H1a include an area set based on the distance from the location of the input terminal 20, an area indicated by a region, metropolitan area, state, prefecture, etc. including the location of the input terminal 20, a pre-determined area including the location of the input terminal 20, an area handled by another user 12 including the location of the input terminal 20, etc.

[0058] Areas that are set based on the distance from the location of the input terminal 20 include land within a predetermined distance from the location of the input terminal 20, areas such as regions, metropolitan areas, states, prefectures, etc. within a predetermined distance from the location of the input terminal 20, areas within a predetermined distance from the location of the input terminal 20, and areas, metropolitan areas, states, prefectures, etc. adjacent to the areas.

[0059] If the location of the input terminal 20 is within the area covered H2, the processing server 15 sets the area covered H2 as the target area H (S24). If the location of the input terminal 20 is not within the area covered H2, the processing server 15 sets the input area H1 as the target area H (S25).

[0060] Returning to Figure 9, the processing server 15 executes the outside-target-area proportion calculation process S15 when the number of target input sheets Na is multiple. In this embodiment, the outside-target-area proportion calculation process S15 is executed when the number of target input sheets Na is equal to or greater than the minimum number Nmin. This outside-target-area proportion calculation process S15 is a process for calculating the outside-target-area business card proportion M1, which is the proportion of business cards 11 having business card address information 17f in a region other than the target area H to the target business cards 11a of the target input number Na.

[0061] The processing server 15 executes a non-target area business card ratio determination process S16 for determining whether the non-target area business card ratio M1 is equal to or smaller than a determination threshold Mmax.

[0062] If the non-target area business card ratio M1 is equal to or less than the determination threshold Mmax, the processing server 15 executes business card exchange date registration processing S17 to register the input date D1 in the business card database 31 as the business card exchange date Da of the target business card 11a.

[0063] If the proportion M1 of business cards outside the target area is greater than the judgment threshold Mmax, the processing server 15 executes a business card exchange date reservation process S18 in which the business card exchange date Da of the target business card 11a is registered as unknown in the business card database 31, or the business card exchange date Da of the target business card 11a is not registered.

[0064] Examples of the determination threshold value Mmax include 10%, 25%, 50%, and a number calculated based on previously registered business card information 31d. In this embodiment, the determination threshold value Mmax is a preset value. The determination threshold value Mmax may be a decimal number or an irrational number.

[0065] By the business card exchange date reservation process S18, business card information 31d whose business card exchange date Da is unknown or not registered can be corrected, for example, by an administrator of the business card management system 10, a person in charge of correction other than the target user 12a, a user 12 other than the target user 12a, the target user 12a's superior, the target user 12a, etc.

[0066] When the processing server 15 executes the business card exchange date reservation processing S18, it executes an alert processing S19 for issuing an alert to the target user 12a. Examples of alerts issued to the target user 12a include outputting alert information from the output device 21 of the input terminal 20, which is the mobile information terminal of the target user 12a, sending an alert message to the contact information of the target user 12a, sending an alert message to the contact information of the target user 12a's boss, etc.

[0067] According to the business card management system 10 and business card management program described above, when a high percentage of business card information 31d has addresses written on business cards 11 that are in a different area from the input area H1 or the area of ​​responsibility H2, for example, because the user 12 inputs business cards 11 exchanged in the past all at once, or inputs business cards 11 exchanged in the past mixed with business cards 11 exchanged on the input date D1, the processing server 15 executes the business card exchange date reservation process S18. This reduces the possibility that a large amount of business card information 31d with an incorrect business card exchange date Da will be registered in the business card database 31, and reduces the effort required to correct the business card information 31d registered in the business card database 31.

[0068] Second Embodiment The following describes a business card management system 10 and a business card management program according to the second embodiment. This embodiment differs from the first embodiment in that the attribute information 35d stored in the user database 35 does not include the user's assigned region information 12h. The following mainly describes the differences from the first embodiment. Note that points not specifically described are the same as those in the first embodiment.

[0069] 10, the processing server 15 derives a responsible area H2, which is an area for which the target user 12a is responsible (S21). In this embodiment, in the target area acquisition process S14, the processing server 15 sets the user address area H2a, which is an area set based on the user address information 12f, as the responsible area H2. The processing server 15 acquires the user address information 12f of the target user 12a from the attribute information 35d stored in the user database 35.

[0070] In this embodiment, the user address region H2a is determined based on the user address information 12f and the map information 33d. Examples of the user address region H2a include a region set based on the distance from the address of the user 12 indicated by the user address information 12f, a range set in advance in the map database 33 that includes the address of the user 12 indicated by the user address information 12f, etc.

[0071] Areas that are set based on the distance from the address of user 12 indicated by user address information 12f include land within a predetermined distance from the address, areas such as regions, metropolitan areas, states, prefectures, etc. within a predetermined distance from the address, areas within a predetermined distance from the address, and areas, metropolitan areas, states, prefectures, etc. adjacent to the area.

[0072] According to the business card management system 10 and business card management program of this embodiment, even if the attribute information 35d does not include information on the individual responsible area B1 as shown in Figure 5 or information on the group responsible area B2 as shown in Figure 6, the responsible area H2, which is the area responsible for the target user 12a, can be derived.

[0073] Third Embodiment The following describes a business card management system 10 and a business card management program according to the third embodiment. This embodiment differs from the first embodiment in that the user's assigned area information 12h is not used to derive the assigned area H2. The following mainly describes the differences from the first embodiment. Note that the points not specifically described are the same as those in the first embodiment.

[0074] 10, the processing server 15 derives a responsible area H2, which is an area for which the target user 12a is responsible (S21). In this embodiment, in a target area acquisition process S14, the processing server 15 estimates the responsible area H2 based on business card address information 17f included in business card information 31d previously registered by the target user 12a.

[0075] Here, the area divided into multiple areas on the map of the map information 33d is defined as a unit area. The number of business cards 11 having business card address information 17f in each unit area is defined as the number Nn of business cards in the unit area. In this embodiment, the processing server 15 estimates the coverage area H2 based on the number Nn of business cards in the unit area.

[0076] In this embodiment, the processing server 15 determines whether the number of business cards Nn in a unit area is equal to or greater than the reference number Nnk. If the number of business cards Nn in a unit area is equal to or greater than the reference number Nnk, the processing server 15 estimates the unit area as its responsible area H2. The responsible area H2 may be one unit area or multiple unit areas.

[0077] In this embodiment, the processing server 15 calculates the number of business cards Nn within a unit area based on at least the map information 33d, the business card address information 17f, and the business card exchange date Da. For example, if the business card exchange date Da is more than a certain period before the date on which the number of business cards Nn within a unit area is calculated, the business card information 31d in which the business card exchange date Da is registered is not used to calculate the number of business cards Nn within a unit area. This allows the coverage area H2 to be estimated taking into account seasonal changes in the addresses of each user 12. Examples of the certain period include one month, 12 months, and 24 months.

[0078] If the number of business cards in a unit area Nn is equal to or greater than the reference number Nnk, the processing server 15 may estimate the unit area and adjacent unit areas to be the area of ​​responsibility H2. The area of ​​responsibility H2 may also be estimated based on the business card acquisition information C1 (see FIG. 5) or the business card acquisition information C2 (see FIG. 6).

[0079] Other Embodiments Next, other embodiments of the business card management system and the business card management program will be described.

[0080] (1) In the above embodiment, an example has been described in which the processing server 15, in cooperation with a plurality of input terminals 20, executes the business card registration process S11 to register the business card information 31d input by each of a plurality of users 12 in the business card database 31. However, the present invention is not limited to such an example. For example, the processing server 15 may be configured to cooperate with a single input terminal 20 to register the business card information 31d input by a plurality of users 12 in the business card database 31. Furthermore, for example, input by a plurality of users 12 may be performed by a single agent. Furthermore, for example, the processing server 15 may be configured to cooperate with a single input terminal 20 to register the business card information 31d input by a single user 12 in the business card database 31.

[0081] (2) In the above embodiment, an example has been described in which the processing server 15 registers the location of the input terminal 20 in the business card database 31 together with the business card information 31d input by each of the multiple users 12 in the business card registration process S11. However, the present invention is not limited to such an example. For example, the location of the input terminal 20 may be registered in the business card database 31 in a process different from the business card registration process S11. Furthermore, for example, the location of the input terminal 20 may not be registered in the business card database 31, but may be derived from the name of the input terminal 20, etc.

[0082] (3) In the above embodiment, the processing server 15 executes the non-target area ratio calculation process S15 by setting the input area H1 as the target area H when the location of the input terminal 20 is outside the assigned area H2, and by setting the assigned area H2 as the target area H when the location of the input terminal 20 is within the assigned area H2. However, the present invention is not limited to such an example. For example, the input area H1 may be set as the target area H regardless of whether the location of the input terminal 20 is within the assigned area H2. For example, the assigned area H2 may be set as the target area H regardless of whether the location of the input terminal 20 is within the assigned area H2. For example, when the location of the input terminal 20 is outside the assigned area H2, or when the location of the input terminal 20 is within the assigned area H2, both the input area H1 and the assigned area H2 may be set as the target area H. In this case, it is possible to reduce the number of registrations of business card address information for areas other than the input area H1 and the assigned area H2, which are likely to be erroneous registrations.

[0083] (4) In the above embodiment, an example has been described in which, when the number of target input sheets Na is less than the minimum number Nmin, the processing server 15 does not execute the outside-target-area proportion calculation process S15, but registers the input date D1 as the business card exchange date Da of the target business card 11a in the business card database 31. However, without being limited to such an example, for example, a configuration may be adopted in which the target area acquisition process S14 and the outside-target-area proportion calculation process S15 are executed regardless of whether the number of target input sheets Na is less than the minimum number Nmin.

[0084] (5) In the above embodiment, the processing server 15 executes the business card registration process S11 each time business card information 31d input by the user 12 is received from the input terminal 20. However, the present invention is not limited to such an example, and may be configured such that the processing server 15 executes the business card registration process S11 collectively for multiple pieces of business card information 31d received from the input terminal 20 on the input date D1.

[0085] (6) In the above embodiment, the processing server 15 executes the target area acquisition process S14 when there is a meeting attended by the target user 12a on the input date D1. However, the present invention is not limited to such an example. For example, the processing server 15 may execute the target area acquisition process S14 regardless of whether there is a meeting attended by the target user 12a on the input date D1. For example, the target area acquisition process S14 may be executed before the minimum number determination process S12 and the attended meeting determination process S13. For example, the attended meeting determination process S13 may be executed before the minimum number determination process S12. For example, the business card management system 10 may not be equipped with a schedule database 34.

[0086] (7) In the above embodiment, an example has been described in which the processing server 15 derives both the input area H1 and the area of ​​responsibility H2 in the target area acquisition process S14. However, the present invention is not limited to such an example. For example, the input area H1 and the area of ​​responsibility H2 may be derived before the target area acquisition process S14, such as in the business card registration process S11. Furthermore, for example, either the input area H1 or the area of ​​responsibility H2 may not be derived.

[0087] (8) In the above embodiment, the processing server 15 executes the alert process S19 to alert the target user 12a when the business card exchange date reservation process S18 is executed. However, without being limited to such an example, for example, the processing server 15 may execute the alert process S19 to alert the target user 12a when the processing server 15 is unable to acquire, from the schedule database 34, the meeting information 34d of the meeting that the target user 12a attended on the input date D1. Also, for example, the processing server 15 may not execute the alert process S19. Also, for example, the processing server 15 may not execute the minimum number determination process S12. Also, for example, the processing server 15 may not execute the attended meeting determination process S13.

[0088] (9) In the above embodiment, the processing server 15 executes the out-of-target-area ratio calculation process S15 when the number of target input sheets Na is more than one. However, the present invention is not limited to such an example. For example, the processing server 15 may execute the out-of-target-area ratio calculation process S15 when the number of target input sheets Na is one or more.

[0089] (10) In the above embodiment, an example has been described in which each of the multiple users 12 is prohibited from inputting the business card information 31d of the business card 11 into the input terminal 20 on a date after the date on which the business card 11 was exchanged. However, the present invention is not limited to such an example, and for example, each of the multiple users 12 may be configured to be able to register the input date D1 from the input terminal 20. Furthermore, for example, a user 12 who has received a warning from the warning process S19 may be configured to be able to change the input date D1 from the input terminal 20.

[0090] (11) In the above embodiment, an example has been described in which the input terminal 20 includes the output device 21. However, the present invention is not limited to such an example. For example, the output device 21 may be provided in the business card management system 10 separately from the input terminal 20.

[0091] (12) The configurations disclosed in the above-described embodiments may be combined with configurations disclosed in other embodiments as long as no contradictions arise. Regarding other configurations, the embodiments disclosed in this specification are merely examples in all respects. Therefore, various modifications may be made as appropriate within the scope of the present disclosure.

[0092] Summary of the above embodiment The business card management system and business card management program according to the present disclosure will be described below.

[0093] In one aspect, the business card management system includes a business card database in which business card information for each of a plurality of business cards is stored, a processing server connected to the business card database, and an input terminal communicably connected to the processing server and configured to accept input of the business card information for one or more of the business cards by a plurality of users, wherein the business card information includes business card address information indicating an address written on the business card, and the processing server is configured to execute a business card registration process in cooperation with the input terminal to register the business card information input by each of the plurality of users in the business card database, wherein one of the plurality of users who input the business card information via the input terminal is a target user, the date on which the business card information was input by the target user is an input date, and the business card for which the business card information was input by the target user within a set period is a target business card, and The processing server sets the number of cards as the target input number, and executes a target area acquisition process to acquire target area information indicating the target area which is at least one of the input area where the target user inputted the business card information and the assigned area which is the area for which the target user is responsible, executes a non-target area proportion calculation process to calculate a non-target area business card proportion, which is the proportion of the number of target business cards which have the business card address information of an area other than the target area among the target input number, and if the non-target area business card proportion is less than or equal to a judgment threshold, executes a business card exchange date registration process to register the input date as the business card exchange date of the target business card in the business card database, and if the non-target area business card proportion is greater than the judgment threshold, executes a business card exchange date pending process to register the business card exchange date of the target business card as unknown in the business card database, or to leave the business card exchange date of the target business card unregistered.

[0094] According to this configuration, when there is a large amount of business card information for business cards that have business card address information outside the target region, the registration of such business card information may not be registration of business card information that was made on the actual business card exchange date, and the business card exchange date can be set to unknown or unregistered. Therefore, when the target user does not input business card information on the day the business cards were exchanged, but inputs business card information related to business cards exchanged in the past, and the proportion of target business cards that have business card address information outside the target region, which is at least one of the input region and the area of ​​responsibility, becomes high, the input date of such business card information may be set to unknown or unregistered, and the business card exchange date can be set to unknown or unregistered. This increases the likelihood that the actual business card exchange date or a date close to it will be registered as the business card exchange date.

[0095] In one aspect, the target area is the input area, and the target terminal area is an area set based on the location of the input terminal where the business card information of the target business card was input, and the processing server sets the target terminal area as the input area in the target area acquisition process.

[0096] According to this configuration, in the non-target area proportion calculation process, the business card exchange date registration process or business card exchange date reservation process is executed based on the proportion of target business cards with business card address information from an area other than the input area to the total number of target input cards. When a user travels to a distant location, for example, on a business trip or participating in an event, there are likely to be more opportunities to exchange business cards. In such cases, if the user inputs business card information after returning from the distant location, the proportion of target business cards with business card address information from a distant area other than the input area is likely to be high. According to this configuration, the input date of such business card information is likely not the actual business card exchange date, and the business card exchange date can be set as unknown or unregistered. This increases the likelihood that the actual business card exchange date, or a date close to it, will be registered as the business card exchange date.

[0097] In one aspect, the processing server, in the business card registration process, registers the location of the input terminal together with the business card information input by each of the plurality of users in the business card database.

[0098] According to this configuration, in the business card registration process, the location of the input terminal is registered in the business card database along with the business card information, so that the business card information of the target business card and the location information of the input terminal where the business card information was entered can be registered in the business card database, and this information can be referenced later.

[0099] In one aspect, the target area is the area of ​​responsibility, and further includes a user database in which attribute information of each of the multiple users is stored, and the attribute information includes at least one of user address information indicating the address of each of the multiple users and user area of ​​responsibility information indicating the area for which each of the multiple users is responsible, and in the target area acquisition process, the processing server sets the user address area, which is an area set based on the user address information, or the area indicated in the user area of ​​responsibility information, as the area of ​​responsibility.

[0100] According to this configuration, in the outside-area proportion calculation process, the business card exchange date registration process or the business card exchange date reservation process is executed based on the proportion of the number of target business cards that have business card address information from an area other than the assigned area among the number of target input cards. Therefore, if the target user does not input business card information on the day they exchanged business cards, but instead inputs business card information related to business cards exchanged in the past, and the proportion of the number of target business cards that have business card address information from an area other than the assigned area increases, the input date of such business card information is likely not the actual business card exchange date, and the business card exchange date can be set as unknown or unregistered. This increases the likelihood that the actual business card exchange date or a date close to it will be registered as the business card exchange date.

[0101] In one aspect, if the number of target input cards is less than the minimum number, the processing server does not execute the outside target area ratio calculation process, and registers the input date as the business card exchange date of the target business card in the business card database.

[0102] According to this configuration, if the number of target input cards is small and the input date is likely to be the actual business card exchange date, and the proportion of business cards from outside the target area is likely to be large, such an input date can be registered in the business card database as the business card exchange date, thereby increasing the possibility that the actual business card exchange date or a date close to it will be registered as the business card exchange date.

[0103] In one embodiment, the average number of registered business cards is the average number of business cards for which business card information has been registered in the past per the set period for each of the multiple users, and the minimum number is set for each user based on the average number of registered business cards.

[0104] According to this configuration, if the number of target input cards is less than the average number of registered cards set for each user based on the average number of registered cards, such an input date is deemed to be likely to be the actual date of business card exchange, and the input date can be registered in the business card database as the business card exchange date. Therefore, it is possible to increase the likelihood that the actual date of business card exchange or a date close to that date will be registered as the business card exchange date.

[0105] In one aspect, a business card management program is provided for a business card management system including a business card database storing business card information for each of a plurality of business cards, a processing server connected to the business card database, and an input terminal communicably connected to the processing server and configured to accept input of the business card information for one or more of the business cards by a plurality of users. The business card management program causes a computer to realize the business card management function of the processing server, wherein the business card information includes business card address information indicating an address written on the business card, one of the plurality of users who input the business card information via the input terminal is a target user, the date on which the business card information was input by the target user is an input date, the business card for which the business card information was input by the target user within a set period is a target business card, and the number of the target business cards is a target input number. A business card registration process is executed to register the business card information in the business card database, a target area acquisition process is executed to acquire target area information indicating a target area which is at least one of an input area where the target user inputted the business card information and a responsible area which is an area for which the target user is responsible, a non-target area proportion calculation process is executed to calculate a non-target area business card proportion, which is the proportion of the number of target business cards which have the business card address information of an area other than the target area to the number of target input cards, and if the non-target area business card proportion is equal to or less than a judgment threshold, a business card exchange date registration process is executed to register the input date as the business card exchange date of the target business card in the business card database, and if the non-target area business card proportion is greater than the judgment threshold, a business card exchange date reservation process is executed to register the business card exchange date of the target business card as unknown in the business card database, or to leave the business card exchange date of the target business card unregistered.

[0106] According to this configuration, when there is a large amount of business card information for business cards that have business card address information outside the target region, the registration of such business card information may not be registration of business card information that was made on the actual business card exchange date, and the business card exchange date can be set to unknown or unregistered. Therefore, when the target user does not input business card information on the day the business cards were exchanged, but inputs business card information related to business cards exchanged in the past, and the proportion of target business cards that have business card address information outside the target region, which is at least one of the input region and the area of ​​responsibility, becomes high, the input date of such business card information may be set to unknown or unregistered, and the business card exchange date can be set to unknown or unregistered. This increases the likelihood that the actual business card exchange date or a date close to it will be registered as the business card exchange date.

[0107] The business card management system and business card management program according to the present disclosure may achieve at least one of the above-described effects. The technical features of the business card management system according to the present disclosure may also be applied to a business card management method. [Explanation of symbols]
