     DESCRIPTION OF EMBODIMENTS 
     Hereinafter, an embodiment of the present invention will be described with reference to the accompanying diagrams. In addition, the same components are denoted by the same reference numerals in all drawings, and the explanation thereof will not be repeated. 
     First Embodiment 
       FIG. 1  is a block diagram illustrating a process configuration example of a coupon information management device  10  in a first embodiment. In  FIG. 1 , the coupon information management device  10  is a device that manages information regarding a coupon available in each store, and includes a visit estimation unit  110 , an available coupon specifying unit  120 , and a non-use determination unit  130 . The coupon managed by the coupon information management device  10  may be an electronic coupon, or may be a non-electronic coupon. In addition, the coupon managed by the coupon information management device  10  indicates a broad concept that means exchange information for giving some benefits to the customer. Forms of the benefits given to the customer by the coupon are not limited. For example, the benefits given to the customer by the coupon are diverse including discounts on goods or services, exchange of goods or services, and granting of a privilege for goods or services. 
     In  FIG. 1 , the coupon information management device  10  further includes a storage unit  200 . Although the example in which the coupon information management device  10  includes the storage unit  200  is shown in  FIG. 1 , other devices that can communicate with the coupon information management device  10  may include the storage unit  200 . 
     The storage unit  200  stores the information of coupons (coupon information) managed in the coupon information management device  10 . Coupon information includes at least a coupon identifier for identifying each coupon. Other pieces of information regarding each coupon, such as the effect of the coupon (discount rate, discount amount, or the like) or a use period, may be included in the coupon information. In addition, the storage unit  200  stores a correspondence relationship among customer identification information, store identification information, and coupon information corresponding to each coupon. Specifically, available store information (store identification information) indicating a store where the coupon is available is associated with the coupon information. The available store information may be included in the coupon information, or may be separately stored so as to be searchable using the coupon identifier of each coupon as a primary key. In addition, available customer information indicating a customer who can use the coupon (customer identification information) is associated with the coupon information. The available customer information may be included in the coupon information, or may be separately stored so as to be searchable using the coupon identifier of each coupon as a primary key. In addition, the storage unit  200  may store, for each customer, classified coupons that each customer can use. 
     The visit estimation unit  110  acquires the customer identification information and the store identification information, and estimates the visit of the customer identified by the customer identification information to the store identified by the store identification information based on the acquired customer identification information and store identification information. Here, the customer identification information is information that can uniquely identify an optional customer, such as a customer ID. The store identification information is information that can uniquely identify an optional store, such as a store ID. 
     Hereinafter, how the visit estimation unit  110  estimates the visit of a customer is illustrated. The method described below does not limit the embodiment of the present invention. 
     As an example, by acquiring “usage declaration information” from a terminal owned by a customer (customer terminal) or a terminal (for example, a customer-available terminal installed in a store) other than the customer terminal, the visit estimation unit  110  can estimate whether or not the customer is in a visiting state in a certain store. 
     The “usage declaration information” is information indicating that the customer has an intention to use the coupon. The usage declaration information is generated based on an input from the customer terminal, for example. Specifically, a customer selects or inputs a coupon, which needs to be used, in the customer terminal or the like, and usage declaration information including coupon information corresponding to the selected or input coupon is generated. Then, the generated usage declaration information is transmitted to the visit estimation unit  110 . In this case, the visit estimation unit  110  can also acquire the customer identification information from the customer terminal. Specifically, the visit estimation unit  110  can acquire a customer identification number by making the customer input the customer identification number, such as the customer ID, together with a coupon that needs to be used. When the usage declaration information is generated using a customer terminal, by acquiring information unique to the customer terminal, such as the serial number of the customer terminal, and transmitting the information together with the usage declaration information, the visit estimation unit  110  can acquire the customer identification information. If the correspondence relationship between the customer identification number and the customer is stored in advance in the storage unit  200 , the visit estimation unit  110  can specify the customer corresponding to the acquired customer identification number using the correspondence relationship. 
     Here, when the customer makes a usage declaration of a coupon, the customer is likely to visit a store where the use-declared coupon is available. Accordingly, the visit estimation unit  110  can estimate the store where the use-declared coupon is available, as a store being visited by the customer, using the usage declaration information. Specifically, the visit estimation unit  110  specifies coupon information corresponding to the coupon information included in the usage declaration information from the coupon information stored in the storage unit  200 . Then, a store where the coupon is available is specified based on the available store information associated with the specified coupon information. When there is a plurality of stores corresponding to the use-declared coupon (for example, a coupon available in common in chain stores), for example, using position information of the customer acquired by a global positioning system (GPS) or the like, the visit estimation unit  110  can estimate a store closest to the position information as a store being visited by the customer. 
     As another example, the visit estimation unit  110  can acquire the position information of the customer and estimate a store, which is present in a predetermined range from the acquired position information, as a store being visited by the customer. For example, the visit estimation unit  110  can acquire position information obtained by the check-in function of the social networking service (SNS) as the position information of the customer. For the position information, for example, the GPS or position information of the customer terminal obtained by the access point of the wireless local area network (LAN) can also be acquired as the position information of the customer. When a store located within a predetermined range from the position information acquired as described above is present, the visit estimation unit  110  can estimate the store as a store being visited by the customer. When a plurality of stores are present in a “predetermined range”, the visit estimation unit  110  can estimate a store closest to the acquired position information as a store being visited by the customer. 
     In addition, the visit estimation unit  110  can also estimate the visit of the customer based on information obtained by using Shopkick (registered trademark) or the like. According to Shopkick (registered trademark), when there is a customer in a store where a device used in Shopkick (registered trademark) is installed, a response signal from the customer terminal is transmitted with respect to the ultrasonic wave transmitted from the device used in Shopkick (registered trademark). When the response signal with respect to the ultrasonic wave is detected, the visit estimation unit  110  can estimate that the customer corresponding to the customer terminal, which has transmitted the response signal, has visited the store. 
     Using the customer identification information and the store identification information acquired by the visit estimation unit  110 , the available coupon specifying unit  120  specifies a coupon available by the customer estimated to be in a visiting state in the store which is estimated to be being visited by the customer by the visit estimation unit  110 , from the storage unit  200 . 
     Specifically, the available coupon specifying unit  120  can specify a coupon, which is available in the store estimated to be being visited by the customer by the visit estimation unit  110 , by comparing the store identification information acquired by the visit estimation unit  110  with the available store information associated with each piece of coupon information stored in the storage unit  200 . The available coupon specifying unit  120  can specify a coupon, which is available by the customer estimated to be in a visiting state by the visit estimation unit  110 , by comparing the customer identification information acquired by the visit estimation unit  110  with the available customer information associated with each piece of coupon information stored in the storage unit  200 . 
     The non-use determination unit  130  detects that each available coupon specified by the available coupon specifying unit  120  has not been used by the customer identified based on the customer identification information acquired by the visit estimation unit  110 . The detection result of the non-use determination unit  130  is stored in the storage unit  200  as a usage situation corresponding to the coupon information of the target. 
     The usage situation of coupons is information associated with the coupon information stored in the storage unit  200 . The usage situation includes at least three states of “used state”, “first unused state”, and “second unused state”. The “used state” indicates a state in which the coupon information was already used. The “first unused state” indicates a state in which a customer did not use a coupon even though the customer was in a situation in which the coupon was available. The “second unused state” indicates a state in which a customer did not use a coupon since the customer was not in a situation in which the coupon was available. The usage situation may be included in the coupon information, or may be separately stored so as to be searchable using the coupon identifier of each coupon as a primary key. In the initial state, the usage situation associated with the coupon information is set to the “second unused state”. 
     As will be described later, when it is determined that the customer visited the store and the coupon was available but the customer did not use the coupon, the non-use determination unit  130  determines the usage situation of the coupon to be the “first unused state”, and sets the usage situation associated with coupon information corresponding to the coupon to be the “first unused state”. In addition, when the customer has used the coupon, the non-use determination unit  130  determines the usage situation of the coupon to be the “used state”, and sets the usage situation associated with coupon information corresponding to the coupon to be the “used state”. 
     Hereinafter, how the non-use determination unit  130  determines that a coupon has not been used is illustrated. The method described below does not limit the embodiment of the present invention. 
     As an example, the non-use determination unit  130  can determine whether or not the usage situation of a coupon included in the usage declaration information is the “first unused state” using the usage declaration information. Specifically, when a predetermined time has passed from the acquisition of the usage declaration information, the non-use determination unit  130  can determine that the coupon included in the usage declaration has not been used. The predetermined time is preferably set to an appropriate value for each store. For example, an average time for which the customer stays in the store, an average time until payment from the visit of the customer, or the like can be counted, and the value can be set as the predetermined time. 
     As another example, when the usage situation of at least one coupon out of the coupons specified by the available coupon specifying unit  120  is set to the “used state”, the non-use determination unit  130  can determine the usage situation of a coupon other than the coupons set to the “used state”, among the coupons specified by the available coupon specifying unit  120 , to be the first unused state. Here, the non-use determination unit  130  can determine whether or not the usage situation of the coupon has been set to the “used state” by using the notification of use, for example. Here, the “notification of use” is information for notifying of a used coupon among the coupons specified by the available coupon specifying unit  120 . For example, the notification of use is generated, during or after adjustment including the use of a coupon, by acquiring coupon information indicating the coupon in the cash register terminal on the store side. The generated notification of use is transmitted to the coupon information management device  10 , and the non-use determination unit  130  can determine the usage situation of the coupon specified by the available coupon specifying unit  120  based on the received notification of use. Other devices excluding the coupon information management device  10  may acquire the notification of use, and the usage situation of the used coupon may be reflected in the storage unit  200 . In this case, the coupon information management device  10  determines whether or not the usage situation of at least one coupon out of the coupons specified by the available coupon specifying unit  120  is set to the “used state” using the usage situation reflected by the other devices. 
     If the coupon information management device  10  further includes a leaving information acquisition unit (not shown) that acquires leaving information indicating that the customer has left the store, the non-use determination unit  130  can determine that the coupon has not been used based on the acquired leaving information. Specifically, if the usage situation associated with the coupon specified by the available coupon specifying unit  120  is not updated to the “used state” until the leaving information of a certain customer is acquired, the non-use determination unit  130  can determine that the coupon has not been used in a state in which the coupon is available. The leaving information can be determined based on the position information of the customer obtained from, for example, the GPS or the check-in information on the SNS, or can be determined based on the presence of a response signal from the customer terminal in Shopkick (registered trademark). 
     [System Configuration] 
     Hereinafter, a mobile POS system including the coupon information management device  10  is illustrated. However, the content of the above embodiment and each embodiment to be described below is not only applicable to the mobile POS system and can be applied to any system that provides a service using a coupon. 
       FIG. 2  is a diagram conceptually illustrating an example of the configuration of a mobile POS system (hereinafter, abbreviated as a POS system)  1  in the present invention. 
     The POS system  1  is configured to include the coupon information management device  10 , a portable information terminal  30 , and a store side configuration  50 . The POS system  1  provides an electronic coupon service for a customer using the portable information terminal  30 , and provides POS service for a store in which the store side configuration  50  is used. The portable information terminal  30  can also be referred to as the customer terminal  30 . 
     The coupon information management device  10  and the store side configuration  50  are communicably connected to each other through a communication network  5 . The communication network  5  is formed by at least one of various forms of communication networks, such as public networks including the Internet, a wide area network (WAN), a local area network (LAN), a communication carrier network, and a wireless communication network. The implementation of the communication network  5  is not limited. 
       FIG. 3  is a diagram conceptually illustrating an example of the hardware configuration of the coupon information management device  10 . The coupon information management device  10  is a so-called computer, and includes a central processing unit (CPU)  11 , a memory  12 , an input and output interface (I/F)  13 , a communication device  14 , and the like that are connected to each other by a bus  15 , for example. The memory  12  is a random access memory (RAM), a read only memory (ROM), a hard disk, or the like. The communication device  14  communicates with other computers or other devices. A portable recording medium or the like may be connected to the communication device  14 . 
     The input and output interface (I/F)  13  can be connected to user interface devices (not shown), such as a display device and an input device. The display device is a device that displays a screen corresponding to drawing data processed by the CPU  11 , a graphics processing unit (GPU; not shown), or the like, such as a liquid crystal display (LCD) or a cathode ray tube (CRT) display. The input device is a device for receiving the input of a user operation, such as a keyboard or a mouse. However, neither a display device nor an input device may be connected to the input and output I/F  13 . The hardware configuration of the coupon information management device  10  is not limited. 
     Each processing unit of the coupon information management device  10  described previously is implemented, for example, by the execution of a program stored in the memory  12  by the CPU  11 . For example, the program may be installed through the input and output I/F  13  from a portable recording medium, such as a compact disc (CD) or a memory card, or other computers on the network, and may be stored in the memory  12 . 
     The customer terminal  30  is a so-called a portable computer, such as a personal computer (PC), a mobile phone, a smartphone, or a tablet terminal. For example, the customer terminal  30  has a hardware configuration shown in  FIGS. 2 and 3 . According to the example shown in  FIG. 2 , the customer terminal  30  has, as a user interface device, a touch panel unit  31  including a display unit and a touch sensor. The display unit includes a monitor, such as a liquid crystal display (LCD) or a cathode ray tube (CRT) display, and performs display processing. A touch sensor receives an operation input from the user by sensing contact from the outside or the proximity state. However, the hardware configuration of the customer terminal  30  is not limited. For example, the user interface device of the customer terminal  30  may be a mechanical keyboard. 
     The store side configuration  50  includes a communication relay device  51 , a store terminal  40 , a stand  52 , a cash drawer  53 , a receipt printer  54 , an electronic money reader and writer  55 , and a credit card reader and writer  56 . The stand  52  is a device for communicably connecting the store terminal  40  and other devices (the cash drawer  53 , the receipt printer  54 , the electronic money reader and writer  55 , the credit card reader and writer  56 , and the like) to each other. The store terminal  40  and the stand  52  are connected to each other, for example, by Bluetooth (registered trademark), short-range wireless communication such as infrared communication, wireless communication such as wireless LAN, or cable communication such as a universal serial bus (USB). The stand  52  and other devices are connected to each other by various communication lines or wirelessly. The communication relay device  51  connects the store terminal  40  to the communication network  5  so that communication between the store terminal  40  and the coupon information management device  10  is possible. In addition, the form of communication between these nodes is not limited. The store terminal  40  may be connected to the communication network  5  using the 3G network through a wireless base station or the like without passing through the communication relay device  51 . The cash drawer  53 , the receipt printer  54 , the electronic money reader and writer  55 , and the credit card reader and writer  56  correspond to part devices included in a general POS register device. 
     The store terminal  40  is the same portable computer as the customer terminal  30 . The store terminal  40  may be the same stationary general-purpose computer as the coupon information management device  10 . For example, the store terminal  40  has a hardware configuration shown in  FIGS. 2 and 3 . According to the example shown in  FIG. 2 , the store terminal  40  has, as a user interface device, a touch panel unit  41  including a display unit and a touch sensor. However, the hardware configuration of the store terminal  40  is not limited. For example, the user interface device of the store terminal  40  may be a mechanical keyboard. 
     Operation Example 
     An operation example of the coupon information management device  10  in the present embodiment will be described with reference to  FIG. 4 .  FIG. 4  is a flowchart illustrating the flow of the process of the coupon information management device  10  in the first embodiment. 
     The coupon information management device  10  acquires customer identification information (S 102 ). In addition, the coupon information management device  10  acquires store identification information (S 104 ). Then, the coupon information management device  10  estimates the visit of a customer corresponding to the customer identification information acquired in S 102  to the store corresponding to the store identification information acquired in S 104  (S 106 ). When it is not estimated that the customer is in a visiting state (S 108 : NO), the coupon information management device  10  ends the process. On the other hand, when it is estimated that the customer is in a visiting state (S 108 : YES), the coupon information management device  10  specifies a coupon that the customer corresponding to the customer identification information acquired in S 102  can use in the store corresponding to the store identification information acquired in S 104  (S 110 ). Then, the coupon information management device  10  determines the use/non-use of the coupon corresponding to the available coupon information specified in S 110  (S 112 ). When it is determined that the available coupon specified in S 110  has not been used (S 112 : non-use determination), the coupon information management device  10  determines the coupon specified in S 110  to be a “state in which the customer did not use the coupon even though the customer was in a situation in which the coupon was available”, that is, “first unused state” (S 114 ), and stores the determination result in the storage unit  200 . On the other hand, when it is determined that the available coupon specified in S 110  has been used (S 112 : use determination), the coupon information management device  10  determines the coupon specified in S 110  to be the “used state” (S 116 ), and stores the determination result in the storage unit  200 . 
     Then, in response to an instruction transmitted from the input device or the store terminal  40  connected to the coupon information management device  10 , the coupon information management device  10  can present a usage situation in a state in which the coupon is available to the user on the store side by displaying the determination result stored in the storage unit  200  on a display device connected to the coupon information management device  10 , a display unit of the store terminal  40 , or the like. 
     As described above, according to the present embodiment, when the visit of a customer to the store is estimated and the customer is estimated to be in a visiting state, a coupon that the customer can use in the store is specified. Then, determination that the specified available coupon has not been used by the customer is made, and this is managed in the storage unit  200 . 
     Specifically, when the specified available coupon was not used, the usage situation associated with the coupon is set to the “first unused state” indicating a state in which the customer did not use a coupon even though the customer was in a situation in which the coupon was available, and this is stored in the storage unit  200 . In addition, the information stored in this manner is presented to the user on the store side through the display device or the like. 
     As described above, according to the present embodiment, “even though a customer had an available coupon, the customer did not use the coupon” can be reliably managed. Therefore, it is possible to extract the useful information that has been buried in the related art. In addition, by determining the effectiveness of each coupon accurately using the extracted information, it is possible to reflect the results in future strategies. 
     Second Embodiment 
     The present embodiment is the same as the first embodiment except for the following points. 
     [Process Configuration] 
       FIG. 5  is a block diagram illustrating a process configuration example of a coupon information management device  10  in a second embodiment. As shown in  FIG. 2 , the coupon information management device  10  of the present embodiment further includes a usage statistics calculation unit  140 . 
     The usage statistics calculation unit  140  calculates the usage statistics of each coupon in a state in which each coupon is available using the statistics of the determination results of the non-use determination unit  130 . Here, the “state in which each coupon is available” refers to a state in which it is estimated that a certain customer has visited a certain store and there is at least one coupon that the customer can use in the store. For example, the “usage statistics of each coupon” may be the number of times in which the coupon was used or the number of times in which the coupon was not used in a state in which the coupon was available, or may be the rate of use or the rate of non-use that is calculated based on these numbers of times and the number of times in which each coupon was available. The usage statistics is calculated for each coupon, and can be an index indicating the effectiveness of each coupon or the like. 
     The usage statistics calculation unit  140  may calculate all of the usage statistics up to date, or may calculate the usage statistics in a part of the period. For example, the usage statistics calculation unit  140  may calculate the usage statistics in a fixed period, such as several weeks or several months, for each coupon. In this case, the non-use determination unit  130  stores date and time information, which indicates the date and time when determination was performed, in association with the determination in the storage unit  200 . The usage statistics calculation unit  140  can calculate the usage statistics in a fixed period using the date and time information associated with the determination result. 
     Operation Example 
     An operation example of the coupon information management device  10  in the present embodiment will be described with reference to  FIG. 6 .  FIG. 6  is a flowchart illustrating the flow of the process of the coupon information management device  10  in the second embodiment. 
     The coupon information management device  10  acquires the usage situation of each coupon stored in the storage unit  200  (S 202 ). In this case, the coupon information management device  10  may further receive conditions, such as a period for calculating the usage statistics or the type of a coupon for which determination results are acquired. In this case, the coupon information management device  10  acquires the determination result corresponding to the received conditions from the storage unit  200 . Then, the coupon information management device  10  calculates the usage statistics of each coupon using the usage situation acquired in S 202  (S 204 ). 
     Then, in response to an instruction transmitted from the input device or the store terminal  40  connected to the coupon information management device  10 , the coupon information management device  10  can present a usage situation in a state in which the coupon is available to the user on the store side in more detail than in the first embodiment by displaying the usage statistics of each coupon calculated by the usage statistics calculation unit  140  on a display device connected to the coupon information management device  10 , a display unit of the store terminal  40 , or the like. 
     As described above, in the present embodiment, the usage statistics of each coupon is calculated using the usage situation of the coupon stored in the storage unit  200 . In addition, the usage statistics calculated in this manner are presented to the user on the store side through the display device or the like. 
     Therefore, according to the present embodiment, “even though a customer had an available coupon, the customer did not use the coupon” can be presented as more understandable usage statistics. In addition, by determining the effectiveness of each coupon more easily using the usage statistics, it is possible to reflect the results in future strategies. 
     In the present embodiment, the usage statistics for each fixed period can be calculated for each coupon. Therefore, according to the present embodiment, it is possible to calculate more detailed usage statistics, such as latest usage statistics of the coupon, usage statistics of the coupon for each season, or usage statistics of the coupon for each day of the week/time zone, for example. In addition, the detailed usage statistics can be used as information to establish a more effective strategy. 
     [Modification Example of the Second Embodiment] 
     In this modification example, customer attribute information is associated with customer identification information, and the non-use determination unit  130  further stores the customer attribute information associated with the customer identification information acquired by the visit estimation unit  110  in the storage unit  200  together with the usage situation. The customer attribute information can be acquired by receiving the input from the customer in advance, for example. The usage statistics calculation unit  140  classifies the determination results stored in the storage unit  200  for each piece of the customer attribute information based on the customer attribute information, and calculates more detailed usage statistics. Here, the “customer attribute information” is information regarding a customer, such as the customer&#39;s age, sex, or address, for example. 
     An operation example of the coupon information management device  10  in this modification example will be described with reference to  FIG. 7 .  FIG. 7  is a flowchart illustrating the flow of the process of the coupon information management device  10  in the modification example of the second embodiment. Different steps (S 302  to S 304 ) from that of the second embodiment will be described below. 
     The coupon information management device  10  classifies the usage situation of each coupon acquired in S 202  based on the customer attribute information that is stored so as to be associated with the usage situation (S 302 ). Then, the coupon information management device  10  calculates the usage statistics of each coupon for each customer attribute based on the determination results classified according to the customer attribute information (S 304 ). In addition, the conditions to classify the usage situation stored in the storage unit  200  can be appropriately changed by the user on the store side. For example, if the user instructs the coupon information management device  10  to classify the usage situation for each age, the usage statistics calculation unit  140  calculates the usage statistics of each coupon based on the usage situation classified based on “customer attribute information: age”. If the user instructs the coupon information management device  10  to classify the usage situation for each sex, the usage statistics calculation unit  140  calculates the usage statistics of each coupon based on the usage situation classified based on “customer attribute information: sex”. 
     As described above, also in this modification example, it is possible to obtain the same effect as in the second embodiment. In addition, in this modification example, the usage situation stored in the storage unit  200  is classified based on the customer attribute information, and the usage statistics of each coupon are calculated based on the classified determination result. 
     Thus, according to this modification example, it is possible to calculate more detailed usage statistics in accordance with the attributes of the customer. Accordingly, it is possible to obtain information to establish a more detailed strategy for each age or sex. 
     While the embodiments of the present invention have been described with reference to the diagrams, these are only illustration of the present invention, and other various configurations can also be adopted. 
     For example, in each of the embodiments described above, a form is assumed in which the coupon information management device  10  manages the coupon information of a plurality of stores. Therefore, in each of the embodiments described above, the coupon information management device  10  specifies a target store from the plurality of stores by further acquiring store identification information that can uniquely identify an optional store, such as a store ID. However, when the coupon information management device  10  is separately provided for each store, the store is already uniquely determined. Therefore, the coupon information management device  10  does not need to acquire store identification information. 
     In this case, the visit estimation unit  110  acquires at least customer identification information, and estimates the visit of the customer, which is identified by the customer identification information, to the store based on the acquired customer identification information. In addition, the storage unit  200  stores at least the correspondence relationship between the customer identification information and coupon information, and the available coupon specifying unit  120  specifies a coupon that the customer estimated to be in a visiting state by the visit estimation unit  110  can use, from the storage unit  200 , based on the customer identification information acquired by the visit estimation unit  110 . 
     In a plurality of flowcharts used in the above explanation, a plurality of steps (processes) are described in order. However, the execution order of the processes performed in each embodiment is not limited to the order of the explanation. In each embodiment, it is possible to change the order of the illustrated steps in a range in which no problem is caused in terms of the content. In addition, the respective embodiments described above can be combined in a range in which the content does not conflict.
