     DETAILED DESCRIPTION 
     The consumer benefit of the electronic receipt system of the related art is limited to a specific company which has introduced the electronic receipt system, where the company is the seller of the product or the service. Therefore, a user of the electronic receipt system may receive the benefits of the electronic receipts separately from each different company which offers electronic receipts. In addition, since each different company may have different user requirements, different registration requirements, and different protocol for interfacing with that company&#39;s electronic receipt system, these systems become difficult for the consumer to use, and to track the receipt information received therefrom. In addition, the consumer must also deal with paper receipts when using a store of a company which has not yet introduced an electronic receipt system. Therefore, it is desirable to promote the introduction of the electronic receipts. 
     In general, according to one embodiment, there is provided an information processing device including a member association unit configured to maintain a code of a consumer, a reception unit configured to receive electronic receipt information and additional information corresponding to the code maintained by the member association unit from an electronic receipt management server, which associates the code of each consumer with the electronic receipt information and other information collected for a plurality of companies, the electronic receipt information including information concerning payments made by the consumer to each of the plurality of companies, and the additional information added to the electronic receipt information, and a display unit configured to display the electronic receipt information and the additional information, which are received by the reception unit. 
     As an application example of the electronic receipt system, it is possible to send additional information such as coupons, which are used to lower the monetary amount paid by a consumer for products and the like, as well as lottery tickets for prize draws which the seller (the company) of the product organizes, by adding the additional information to the electronic receipt. It is possible to manage all of the additional information using electronic receipt application software. In the application software, it is possible to display any coupons receiver from a company in a list, to select a coupon from the list and display the coupon, and the like. 
     Hereinafter, description will be given of an embodiment on the basis of the drawings. 
       FIG. 1  is a configuration diagram showing the overall configuration of an electronic receipt system according to the embodiment. As shown in  FIG. 1 , a point of sales (POS) terminal  2  (only one is shown in  FIG. 1 , however, there may also be a plurality), which is a product sales data processing device which executes product sales data processing, and a router  3  are installed in a store  1 . The POS terminal  2  and the router  3  are connected using an in-store Local Area Network (LAN)  4 . The router  3  is a device for connecting the in-store LAN  4  to the Internet or a network  5 , which is a virtual private network (VPN). Furthermore, while not particularly shown in the drawings, the store  1  may also be provided with a store server, which controls the POS terminal  2 . 
     An electronic receipt server  6  is connected to the network  5 . A plurality of electronic receipt servers  6  are provided to manage electronic receipt and other related information for each company which sells products or services and has a physical store or a chain store (hereinafter referred to as a store) such as a convenience store, a supermarket, a foodstuff vendor, a drugstore, an apparel vendor, a home electronic appliances vendor, a department store, a household goods store or a catering establishment that is a member of the electronic receipt system. The electronic receipt server  6  functions as a corporate receipt management server, which stores and manages electronic receipt information by each company code, the code indicating the company that administers the store. Furthermore, the electronic receipt server  6  may also be configured to interface with a head office server of a POS system, which includes functions such as sales management, sales analysis and stock management of each company which administers a store. 
     In addition, a portable terminal  8  is connected to the network  5  via a base station  7 , which performs wireless communication according to a standard such as wireless fidelity (Wi-Fi). The portable terminal  8  is an information processing device, which implements a web browser, such as a smart phone, a mobile telephone, a personal digital assistant (PDA) or a tablet computer, for example. Furthermore, instead of the portable terminal  8 , an information processing device such as a personal computer such as a notepad PC may also be used. 
     Furthermore, an electronic receipt management server  9 , which functions as a customer receipt management server that collectively stores and manages the electronic receipt information of various companies that maintain stores is also connected to the network  5 . A consumer who is pre-registered as a member in order to receive electronic receipt service may obtain electronic receipt information from the electronic receipt management server  9  using the portable terminal  8 , via the network  5 . The electronic receipt management server  9 , for example, is managed by a third party organization other than the company which manages the electronic receipt information using the electronic receipt server  6 .

     Furthermore, member registration by a consumer to enable the consumer to receive electronic receipts from the electronic receipt service is performed in the following manner. The consumer transmits an empty, i.e., blank email from the portable terminal  8  to a member management server via the network  5 . The member management server transmits a uniform resource locator (URL), which indicates a page for performing member registration, to the email address of the received email. The consumer accesses the URL of the page for performing member registration from the portable terminal  8 , causes the portable terminal  8  to display the input screen of the registration page and inputs the necessary items thereinto to obtain member registration. An input confirmation screen is displayed on the portable terminal  8  after the consumer completes the input of the necessary items. Furthermore, after the consumer confirms the input, the member registration is executed in relation to a member master list. Subsequently, the member management server distributes a member registration completed mail, which includes a member code and a password, to the portable terminal  8 . Accordingly, the member registration is completed. Furthermore, after the completion of the registration, a “top screen display” button is provided on the registration complete screen, which is displayed on the portable terminal  8 . By operating the “top screen display” button, the portable terminal  8  displays the top screen. 
     In the electronic receipt system configured as described above, the electronic receipt information that shows payment information, which is generated by performing product sales data processing using the POS terminal  2  of the store  1 , is transmitted to the electronic receipt management server  9  via the electronic receipt server  6  via the network  5 . The electronic receipt information is transmitted from the electronic receipt management server  9  to the portable terminal  8  of a member. The member causes the display unit of the portable terminal  8  to display the electronic receipt information, and may confirm the content thereof. In addition, the electronic receipt management server  9  publishes the electronic receipt information on the web. The portable terminal  8 , which implements a web browser, by specifying a uniform resource locator (URL), may download the electronic receipt information, which is published on the web, to the portable terminal  8  and view the electronic receipt information using the web browser. Furthermore, a configuration may also be adopted in which application software for viewing the electronic receipt information is installed on the portable terminal  8  and the electronic receipt information is viewed using the application software. 
     The portable terminal  8  stores the member code and password, which the consumer acquires in the manner described above, in a storage unit  13  (refer to  FIG. 2 ). As the output method of the member code, which is stored in this manner, display by bar-code, display by two-dimensional code, transmission by information communication using near field communication (NFC), which is near field wireless communication, and the like may be used. 
     Furthermore, association between the member code, which is acquired in order for the consumer to receive the electronic receipt service, and an existing company member card of a point service or the like, i.e., a customer loyalty program, which is administered by a company such as a chain store or the like, may be realized using the POS terminal  2  of each retail store or the portable terminal  8  of each individual person. 
     Here, description will be given of an operation example of establishing a relationship between the member code, which is acquired by the consumer as described above, and the existing company member card. 
     1. Operation Example in POS Terminal  2  of Store 
     (1) First, a checker, who operates the POS terminal  2 , confirms whether or not to provide the electronic receipt service during a consumer&#39;s purchase of a product (payment), and confirms the presence of a point card. When the electronic receipt service is to be carried out, the consumer presents the portable terminal  8  and the point card. 
     (2) The checker reads the member code stored in the portable terminal  8  and the company member code of the point card, respectively. Here, the reading of the member code stored in the portable terminal  8  depends on an input-output provided in the POS terminal  2 . For example, when the POS terminal  2  is provided with a code reader that reads code symbols, the member code, which is held in a bar-code or a two-dimensional code, is read. In addition, when the POS terminal  2  is provided with a short range wireless device, which conforms to NFC or the like, the member code, which is held in an IC tag or the like, is read. 
     (3) The POS terminal  2  transmits a transaction, the member code read in (2) and the company member code of the point card to the electronic receipt management server  9 . 
     (4) The electronic receipt management server  9  receives the information transmitted in (3), and registers the electronic receipt information indicating a payment amount, which is generated by performing product sales data processing using the POS terminal  2  of the store  1 , and the member code to the electronic receipt management server  9 . In addition, when the company member code of the point card is transmitted for the first time at the same time as the electronic receipt information and the member code, the company member code is also registered to the electronic receipt management server  9 . 
     Hereinafter, the consumer may receive the service of the electronic receipt system and the point addition service by presenting only the portable terminal  8  or the point card. 
     2. Operation Example in Portable Terminal  8   
     (1) First, the consumer logs into a point card registration menu by accessing a specific URL from the portable terminal  8 , which the consumer owns, or by using an application, which is installed on the portable terminal  8 . The consumer inputs or selects the company that issues the point card, which is the registration target. Next, the consumer inputs the company member code of the point card, which is the registration target, confirms the number, subsequently presses the registration button, and the registration content is transmitted to the electronic receipt management server  9 . Furthermore, the company member code may be input using manual input, camera photography, magnetic reading and the like. 
     (2) The electronic receipt management server  9  receives the registration content from the portable terminal  8  in (1), matches the registration content with the customer information of each company, and replies to the portable terminal  8  of the consumer with a confirmation display screen. 
     (3) The consumer confirms the confirmation display screen that is returned from the electronic receipt management server  9 , and the association of the member code of the electronic receipt system and the existing company member card is completed by pushing the agreement button. 
     According to the above description, the service and the point addition service in the electronic receipt system are managed using a unique member code of the electronic receipt system. Therefore, it is possible to receive a loyalty program service in the electronic receipt system by presenting a point card in a store for which a point card of the related art is owned, and by presenting the portable terminal  8  in a store for which a point card is not owned. As a result, it is possible for the electronic receipt system to act as a hub, which relates associates the member code of the electronic receipt with each company member card of each company.

The CPU  21  then determines whether or not there is an electronic receipt issuing command, which corresponds to the payment process that corresponds to the finalizing operation (step S 1 ). 
     In order for the member to indicate the electronic receipt issuing command, a method such as the one shown below may be considered, for example. 
     1. The clerk operates an “issue electronic receipt” button, which is provided on the input unit  31  (for example, a keyboard) of the POS terminal  2 .
 
2. The consumer, who is the member, displays a bar-code that includes a code on the display unit  17  of the portable terminal  8 . The clerk then reads the bar-code using the input unit  31  (for example, a bar-code scanner) of the POS terminal  2 .
 
3. The consumer, who is the member, operates an “issue electronic receipt” button, which is displayed on the customer display unit  30  so as to be possible to press.
 
4. The consumer, who is the member, displays a bar-code that includes a code on the display unit  17  of the portable terminal  8 . The consumer, who is the member, then reads the bar-code using the input unit  31  (for example, a bar-code scanner (preferably a separate scanner from the scanner used for product registration)) of the POS terminal  2  in person.
 
5. The consumer, who is the member, presents the company member card for receiving the point service, and reads the company member code of the company member card using the input unit  31  (for example, a bar-code scanner, a magnetic card reader, NFC or the like) of the POS terminal  2 . When the member code of the electronic receipt is related to the read company member code, an electronic receipt issuing command is determined to be present.
 
     The CPU  21  (the electronic receipt generation unit  26 ) of the POS terminal  2  waits until an electronic receipt issuing command is present (No in step S 1 ). When the CPU  21  (the electronic receipt generation unit  26 ) of the POS terminal  2  determines that there is an electronic receipt issuing command (Yes in step S 1 ), the product transaction data is transmitted to the head office server, the CPU  21  generates the electronic receipt information by extracting the company code (the identification code of the company that owns or operates the store), the business type or business category code, the store code, the member code of the consumer, the POS number of the POS terminal  2 , the receipt number, the product sales data, the additional information and the like from the identification code management region  23   a , the additional information management region  23   b  or the like, which are provided in the storage unit  23 , on the basis of the separately received or maintained product information and the payment information that is registered during the payment according to the product sales data processing (step S 2 ). 
     Next, the CPU  21  (the transmission unit  27 ) of the POS terminal  2  connects to the in-store LAN  4  and the network  5  via the network interface  24 , transmits the generated electronic receipt information to the electronic receipt server  6  (step S 3 ) and ends the process. Furthermore, when the electronic receipt issuing command is determined not to be present, a paper receipt is issued by printing, the product transaction data is transmitted to the head office server, and the process is ended. 
     Furthermore, when the CPU  21  of the POS terminal  2  is offline during the transmission of the product transaction data (transaction data) to the head office server, problems are avoided by performing the following information handling sequence. 
     1. Automatically carry out retry transmission.
 
2. When step  1  is insufficient to handle the difficulty, the product transaction data (transaction data) is stored until online restoration and is broadcast to the head office server after online restoration. In this case, the CPU  21  of the POS terminal  2  performs display such as “the product transaction data (transaction data) will be transmitted later” on the operator display unit  28 .
 
     Next, description will be given of the flow of the information transmission process, which is executed by the CPU  41  of the electronic receipt server  6  operating in accordance with the electronic receipt management process and the information transmission program P 2 , which are executed by operating in accordance with the electronic receipt management program P 1 , with reference to the flow chart shown in  FIG. 8 . 
     When the CPU  41  of the electronic receipt server  6  receives the electronic receipt information, which is transmitted from the POS terminal  2 , via the network interface  44  (Yes in step S 11 ), the received information is stored in the electronic receipt management region  43   a  of the storage unit  43  as electronic receipt information for each company (step S 12 ). In other words, the CPU  41  of the electronic receipt server  6  functions as an electronic receipt management unit, which manages the electronic receipt information in the storage unit  43  maintained by selling company corresponding to the company codes. 
     In addition, after the CPU  41  of the electronic receipt server  6  stores the received electronic receipt information, when a preset transmission timing is reached (No in step S 11  and Yes in step S 13 ), the additional information, which is managed by the information management region  43   b , and the electronic receipt information, which is managed by the electronic receipt management region  43   a , are transmitted to the electronic receipt management server  9  (step S 14 ), and the process returns to step S 11 . 
     Furthermore, in the above description, the CPU  21  (the electronic receipt generation unit  26 ) of the POS terminal  2  generates the electronic receipt information and transmits the electronic receipt information to the electronic receipt server  6 . However, the present disclosure is not limited thereto. For example, the CPU  21  of the POS terminal  2  transmits the store code, the member code of the consumer, the POS number of the POS terminal  2 , the receipt number, the product sales data and the like to the electronic receipt server  6  on the basis of the product information and the payment information, which are registered during payment according to the product sales data process. Therefore, the CPU  41  of the electronic receipt server  6  may generate electronic receipt information by adding the company code, the business type or business category code, the additional information or the like to the data transmitted thereto. 
     Next, description will be given of the flow of the product information transmission process, which is executed by the CPU  51  of the electronic receipt management server  9  operating in accordance with the electronic receipt management process and the information transmission program P 4 , which are executed by operating in accordance with the electronic receipt management program P 3 , with reference to the functional block diagram shown in  FIG. 9  and the flow chart shown in  FIG. 10 . 
     As shown in  FIG. 9 , the electronic receipt management program P 3  and the information transmission program P 4  that are executed by the electronic receipt management server  9  have a modular configuration including a reception unit  55 , an electronic receipt batch management unit  56  and an electronic receipt transmission unit  57 . Each component described above is loaded into the memory  52  by the CPU  51  reading out, from the storage unit  53 , and executing the electronic receipt management program P 3  and the information transmission program P 4 . Therefore, the reception unit  55 , the electronic receipt batch management unit  56  and the electronic receipt transmission unit  57  are generated in the memory  52 . 
     The reception unit  55  receives the electronic receipt information broken down by selling company. The electronic receipt information includes the company code that indicates the company that owns or operates the store and is electronically processed instead of a printed the receipt a. 
     The electronic receipt batch management unit  56  stores the electronic receipt information, which is received using the reception unit  55 , broken down by company in the electronic receipt management region  53   a  of the storage unit  53 , and manages the electronic receipt information collectively. 
     In relation to the portable terminal  8 , which is associated with the member code of a designated consumer, the electronic receipt transmission unit  57  acquires the electronic receipt information, which is associated with the member code and includes at least one or more company codes, from the electronic receipt management region  53   a  and transmits the acquired electronic receipt information. 
     As shown in  FIG. 10 , the CPU  51  (the reception unit  55 ) of the electronic receipt management server  9  determines whether or not the electronic receipt information and the additional information, which are transmitted from the electronic receipt server  6  of each company, have been received via the network interface  54  (step S 21 ). 
     When the electronic receipt information and the additional information are received (Yes in step S 21 ), the CPU  51  (the electronic receipt batch management unit  56 ) of the electronic receipt management server  9  stores the electronic receipt information and the additional information of the various companies in the electronic receipt management region  53   a  of the storage unit  53  collectively (step S 22 ). 
     In addition, after the CPU  51  (the electronic receipt transmission unit  57 ) of the electronic receipt management server  9  stores the electronic receipt information and the additional information in the electronic receipt management region  53   a  collectively, the CPU  51  transmits the electronic receipt information and the additional information to the portable terminal  8  (step S 23 ) and returns to step S 21 . Furthermore, when the transmission of the electronic receipt information is completed, the transmission results of the electronic receipt information may be managed by storing a flag that signifies the completion of the transmission in relation to the electronic receipt information of the electronic receipt management region  53   a.    
     In addition, when there is a query of the electronic receipt information from the portable terminal  8  (No in step S 21  and Yes in step S 24 ), the CPU  51  (the electronic receipt transmission unit  57 ) of the electronic receipt management server  9  extracts the additional information and the electronic receipt information, which are managed in the electronic receipt management region  53   a , according to the content of the query of the electronic receipt information (step S 25 ), subsequently transmits the queried additional information and the electronic receipt information to the portable terminal (step S 26 ) and returns to step S 21 . 
     Next, description will be given of the flow of the electronic receipt viewing process, which is executed by the CPU  11  of the portable terminal  8  operating in accordance with the electronic receipt receiving process and the electronic receipt viewing program P 12 , which are executed by operating in accordance with the electronic receipt handling program P 11 , with reference to the functional block diagram shown in  FIG. 11  and the flow chart shown in  FIG. 12 . 
     As shown in  FIG. 11 , the electronic receipt handling program P 11 , the electronic receipt viewing program P 12  and the additional information viewing program P 12   a  that are executed by the portable terminal  8  have a modular configuration including a member association unit  81 , which functions as the member association means, an electronic receipt reception unit  82 , which functions as the reception means, and an electronic receipt display unit  83 , which functions as the display means. Each component described above is loaded into the memory  12  by the CPU  11  reading out, from the storage unit  13 , and executing the electronic receipt handling program P 11 , the electronic receipt viewing program P 12  and the additional information viewing program P 12   a . Therefore, the member association unit  81 , the electronic receipt reception unit  82  and the electronic receipt display unit  83  are generated in the memory  12 . 
     The member association unit  81  associates the member code of a designated consumer with the electronic receipt information. 
     The electronic receipt reception unit  82  receives (acquires) the electronic receipt information and the additional information, which correspond to the member code that is associated by the member association unit  81 , from the electronic receipt management server  9 , which manages the electronic receipt information collectively. 
     The electronic receipt display unit  83  sorts the electronic receipt information and the additional information, which are received by the electronic receipt reception unit  82 , sorted by units of company code or the like, and displays the electronic receipt information and the additional information on the display unit  17 . 
     As shown in  FIG. 12 , first, the CPU  11  (the member association unit  81 ) of the portable terminal  8  accesses the electronic receipt management server  9  and executes an authentication process using the input of the member code and the password (step S 31 ). Accordingly, the portable terminal  8  and the member code of a designated consumer are associated with one another. 
     After the authentication, the CPU  11  (the electronic receipt reception unit  82 ) of the portable terminal  8  receives the electronic receipt information and the additional information, which are managed in the electronic receipt management region  53   a  corresponding to the input member code (step S 32 ). Furthermore, the reception of the electronic receipt information and the additional information may also be received using electronic mail. 
     Next, the CPU  11  (the electronic receipt display unit  83 ) of the portable terminal  8  displays the purchase date included in the electronic receipt information on the display unit  17  as a list (step S 33 ). The portable terminal  8  prompts the user, who is the consumer, to select the information by displaying the purchase date on the display unit  17  as a list in this manner. 
     When the CPU  11  (the electronic receipt display unit  83 ) of the portable terminal  8  determines that the store is selected by the user by the desired date (Yes in step S 36 ), the CPU  11  displays the electronic receipt information, which corresponds to the store selected by date, on the display unit (step S 37 ). 
       FIG. 13  is a front view showing a display example Z in relation to the display unit  17  of the portable terminal  8 . As shown in  FIG. 13 , the display example Z is a display of the electronic receipt information of a desired store on a desired day on which the user, who owns the portable terminal  8  that accesses the electronic receipt management server  9 , went shopping. The display example Z has a similar layout to that of a paper receipt by analyzing the electronic receipt information, and the member&#39;s focus may be set to a product a using a cursor which follows the input of the input unit  18  within the display, or the focus may be set to an icon b (in  FIG. 13 , the button-shaped icon labeled as “apply”), which represents the various additional information that is associated with the product. 
     Here, when the user selects an appropriate product or an icon, which is associated with the product, (Yes in step S 38 ), the CPU  11  (the electronic receipt display unit  83 ) of the portable terminal  8  connects to the network  5  via the network interface  14 , acquires various information from the network  5  on the basis of the access information, which is related to the selected product or icon, and displays the information on the display unit  17  (step S 39 ). 
     For example, when, as the access information in relation to the product a, a home page related to the product is set as a product information link, the home page, which is related to the product, is displayed on the display unit  17  when the desired product is selected. 
     In addition, when a home page related to an application campaign is set as the access information in relation to a button-shaped icon b labeled as “apply”, the application campaign page related to the “apply” button is displayed on the display unit  17  when the “apply” button is selected. 
     In addition, when a home page related to a CM is set as the access information in relation to a banner c, which is a type of icon, the CM related to the banner c is displayed on the display unit  17  when the banner c is selected. 
     When the end of the electronic receipt viewing process is declared from an input unit  18  (Yes in step S 40 ), the CPU  11  of the portable terminal  8  ends the process. 
     When the end of the electronic receipt viewing process is not declared from the input unit  18  (No in step S 40 ), the CPU  11  of the portable terminal  8  returns to step S 38  and waits for the selection of a product or an icon that is associated with a product. 
     In addition, as described in step S 24  of  FIG. 10  described above, a case in which, instead of accessing the electronic receipt management server  9  from the portable terminal  8 , the portable terminal  8  receives the electronic receipt information and the additional information from the electronic receipt management server  9  is also described with reference to the flow chart of  FIG. 14 . 
     The CPU  11  (the electronic receipt reception unit  82 ) of the portable terminal  8  receives the electronic receipt information and the additional information from the electronic receipt management server  9  (step S 61 ). 
     Subsequently, when the electronic receipt viewing program P 12  is run (Yes in step S 62 ), the CPU  11  (the electronic receipt display unit  83 ) of the portable terminal  8  relates the received electronic receipt information and additional information with the company code and displays the electronic receipt information and the additional information (step S 63 ). 
       FIG. 15  is a front view showing a display transition example in relation to the display unit  17  of the portable terminal  8 . A display example O shown in  FIG. 15  sorts the electronic receipt information by company code, in the order received from the electronic receipt management server  9 , and displays the electronic receipt information. In the display example O shown in  FIG. 15 , one item of electronic receipt information may be selected using a flick operation (the sliding of a finger to the left or right) or touch in relation to the input unit  18  (a touch panel laminated onto the display unit  17 ). In addition, as shown in the display example O shown in  FIG. 15 , a message “coupon present” is displayed as the additional information on the electronic receipt to which a coupon was added. 
     When one item of electronic receipt information is selected, as shown in a display example P shown in the left side of  FIG. 15 , the selected electronic receipt information is displayed on the display unit  17  of the portable terminal  8 . The display example P has a similar layout to that of a paper receipt by analyzing the electronic receipt information, and it is possible to scroll in relation to the input unit  18  (a touch panel laminated onto the display unit  17 ) within the display. In addition, operation in relation to the icon b (the button-shaped icon labeled as “coupon information” in  FIG. 15 ), which represents various additional information associated with the product, may be performed via the input unit  18  (a touch panel laminated onto the display unit  17 ). 
     First, description will be given of the flow of the statistical information generation process, which is executed by the CPU  11  of the portable terminal  8  operating in accordance with the statistical information generation program P 13 , with reference to the flow chart shown in  FIG. 16 . 
     The CPU  11  of the portable terminal  8  accesses the electronic receipt management server  9  and executes the authentication process using the input of the member code and the password (step S 51 ). 
     After the authentication, when the CPU  11  of the portable terminal  8  determines that the input of the information necessary to generate the statistical information, such as the period for which to generate the statistical information and the type of the statistical information, is present (Yes in step S 52 ), the CPU  11  receives the electronic receipt information, which is managed in the electronic receipt management region  53   a  corresponding to the input member code and the information necessary to generate the statistical information (step S 53 ). 
     Next, the CPU  11  of the portable terminal  8  generates the statistical information that is statistically collected (sorted or categorized) on the basis of the information (for example, the company code or the business type or business category code) necessary to generate the statistical information from the acquired electronic receipt information (step S 54 ), and displays the generated statistical information on the display unit  17  (step S 55 ). 
     Next, description will be given of the flow of the additional information viewing process, which is executed by the CPU  11  of the portable terminal  8  operating in accordance with the electronic receipt receiving process and the additional information viewing program P 12   a , which are executed by operating in accordance with the electronic receipt handling program P 11 , with reference to the flow chart shown in  FIG. 17 . Furthermore, the process may also be executed as a portion of the electronic receipt viewing process described above. 
     As shown in  FIG. 17 , the CPU  11  (the electronic receipt reception unit  82 ) of the portable terminal  8  receives the electronic receipt information and the additional information from the electronic receipt management server  9  (step S 71 ). 
     Subsequently, when the additional information viewing program P 12   a  is run (Yes in step S 72 ), the CPU  11  (the electronic receipt display unit  83 ) of the portable terminal  8  associates the received additional information with the company code and displays the additional information (step S 73 ). 
       FIG. 18  is a front view showing a display example in relation to the display unit  17  of the portable terminal  8 . A display example L shown in  FIG. 18  sorts the additional information in the order received from the electronic receipt management server  9 , and displays the additional information. In  FIG. 18 , an example is shown in which “coupon A” or the like is displayed as the type of the additional information. However, even with other additional information, a textual string or the like indicating the type thereof is displayed. 
     In the display example L of  FIG. 18 , when the company trademark displayed on the display unit  17  is selected by a touch operation, the CPU  11  (the electronic receipt display unit  83 ) of the portable terminal  8  sorts the additional information added to the store of the company that is touched in the time series order in which electronic receipts including the additional information are issued (generated), and the CPU  11  displays the additional information as a list (refer to  FIG. 19 ). By displaying information relating only to the stores of companies with a high usage frequency by the customer on the list, the additional information added to the stores is easy to understand. Furthermore, the element used as the sorting reference is not limited to the examples described above. For example, the sorting may also be performed by the type of the additional information, by the various elements relating to the additional information and the like. 
     In addition, in the display example L of  FIG. 18  (or  FIG. 19 ), when the additional information (a coupon or a lottery ticket) displayed on the display unit  17  is selected by a touch operation, the CPU  11  (the electronic receipt display unit  83 ) of the portable terminal  8  performs detailed display relating to the additional information. Here, the method of the detailed display is not particularly an issue. For example, as shown in  FIG. 15 , the electronic receipt to which additional information is added may also be displayed. In addition, when content such as textual information and image data is held in the additional information itself, the content thereof may also be displayed. In addition, when access information such as a URL is held in the additional information, the link destination indicated by the access information is accessed and the content provided from the link destination may also be displayed. 
     In this manner, according to the display example L, since detailed display of the additional information may be easily performed, user friendliness may be improved. Furthermore, the display example of the additional information is not limited to the examples described above. For example, an embodiment may also be adopted in which only the additional information is displayed in a list format or the like. 
     In addition, the electronic receipt information may also be shared between the members of the electronic receipt system. By interrelating a plurality of the member codes, sales data of the products that each individual purchases may be shared with, for example, a family, a group, a department of a company or the like. 
     In this manner, according to the electronic receipt system of the embodiment, since, unlike the electronic receipt (and the additional information) system dedicated to specific companies of the related art, the electronic receipt system hereof may be implemented to go beyond the company scope, and the acceptance of the electronic receipts may be promoted. 
     For example, in the embodiment, a configuration is adopted in which the additional information is added to the electronic receipt information in the POS terminal  2  or the electronic receipt server  6 . However, the embodiment is not limited thereto, and a configuration may also be adopted in which the additional information is added in the electronic receipt management server  9 . Hereinafter, such an embodiment is described as a modification example of the embodiment described above. 
     Modification Example 
     In the modification example, description will be given using a campaign (an event) such as a lottery, which is performed in a shopping center having a plurality of stores  1 . Furthermore, in the modification example, the storage unit  53  of the electronic receipt management server  9  associates the store codes of each store  1 , which comprise the shopping center, and stores and manages the event information relating to the events as the additional information. Here, the event information includes, for example, an event ID for identifying each event, the conditions relating to participation (application) in the events and the like. 
     In addition, in the modification example, the storage unit  53  of the electronic receipt management server  9  stores and manages application status information relating to the event as the additional information and associates the additional information with the electronic receipt information of each company that relates to an event (an event ID), of the electronic receipt information of each user stored and managed in the electronic receipt management region  53   a . Here, the application status information includes, for example, a flag of whether or not application is complete, number of times applied (application times) and the like. 
       FIG. 20  is a flow chart showing the flow of the electronic receipt receiving process and the additional information viewing process, which are executed by the portable terminal  8 , according to the modification example. Furthermore, the process may also be executed as a portion of the electronic receipt viewing process described above. 
     As shown in  FIG. 20 , the CPU  11  (the electronic receipt reception unit  82 ) of the portable terminal  8  receives the electronic receipt information and the additional information (the event information and the application status information) from the electronic receipt management server  9  (step S 81 ). 
     Here, the CPU  51  of the electronic receipt management server  9  transmits the event information, which is associated with the store code of the electronic receipt information on the basis of the electronic receipt information including the member code of the portable terminal  8 , to the portable terminal  8  as the additional information. Here, the CPU  51  of the electronic receipt management server  9  transmits the application status information, which is associated with the electronic receipt information of the transmission target, to the portable terminal  8  as the additional information. 
     Furthermore, the transmitting and receiving of the event information is not limited to being performed during transmitting and receiving of the electronic receipt information. For example, in the portable terminal  8 , the event information relating to the events being carried out in the shopping center may be acquired by specifying the location or the like of the shopping center. Here, the designation of the location or the like may also be performed manually via the input unit  18 . In addition, when the portable terminal  8  includes a GPS function or the like, which is capable of acquiring the positional information of the device itself, the location may also be designated using the positional information of the shopping center that is acquired using the function. 
     When the GPS function or the like is used, the CPU  11  of the portable terminal  8 , as shown in a display example N 1  of  FIG. 21 , for example, may also be configured such that a button n 1 , which commands the searching of an event, is displayed and the positional information is input according to the operation of the button n 1 . In addition, when such an embodiment is adopted, the electronic receipt management server  9  holds an address specification table, which may specify the address (the shopping center or the like) of the store  1  from the store code of each store  1 . Furthermore, the CPU  51  of the electronic receipt management server  9  specifies the shopping center that corresponds to the command information received from the portable terminal  8  and transmits the event information, which is associated with the store  1  (the store code) of the shopping center, to the portable terminal  8 . 
     Returning to  FIG. 20 , when the additional information viewing program P 12   a  is run on the portable terminal  8  (Yes in step S 82 ), the CPU  11  (the electronic receipt display unit  83 ) of the portable terminal  8  displays the received additional information (the event information) on the display unit  17  (step S 83 ). 
       FIG. 22  is a front view showing a display example in relation to the display unit  17  of the portable terminal  8 . A display example N 2  shown in  FIG. 22  displays the event information received from the electronic receipt management server  9 . In  FIG. 22 , an example in which two items of event information n 2  and n 3  are displayed is shown, and one of the items of event information (events) may be selected. 
     When the CPU  11  of the portable terminal  8  receives the selection of the event (Yes in step S 84 ), as shown in  FIG. 23 , a participation confirmation screen for confirming participation in the event is displayed on the display unit  17  (step S 85 ). Furthermore, when an event is not selected due to the operation or the like of another button (No in step S 84 ), the process ends. 
     A display example N 3  shown in  FIG. 23  is a display example of the case in which the event information n 2  of  FIG. 22  is selected. In addition, the display example N 3  displays condition information n 4  included in the event information, and displays a button n 5  for requesting participation in the event. In the condition information n 4 , the condition is that it is possible to apply a one-time US$10 purchase monetary amount (or the sum value of the purchase monetary amounts) at the shopping center. 
     When the CPU  11  (the electronic receipt display unit  83 ) of the portable terminal  8  receives the participation command to the event according to the operation of the button n 5  (Yes in step S 86 ), as shown in  FIG. 24 , an application status screen, which performs detailed display of the event for which participation is requested, is displayed on the display unit  17  (step S 87 ). Furthermore, when participation in an event is not requested due to the operation or the like of another button (No in step S 86 ), the process ends. 
       FIG. 24  is a front view showing a display example in relation to the display unit  17  of the portable terminal  8 . A display example N 4  shown in  FIG. 24  displays the application status screen of the event information n 2 , in which participation is requested in  FIG. 23 . Here, an application times n 6  displays the application times included in the application status information. In addition, the total value of the sales sum values included in the electronic receipt information received in step S 81 , that is, included in the electronic receipt information issued by each store  1  (shopping center) relating to the event, is displayed as a total n 7 . 
     Here, the total n 7  may display the total value of the sales sums without change. Alternatively, display control may also be performed such that the total n 7  is a value obtained by subtracting the integrated value of the monetary amount (US$10) defined in the condition information and the application times (1 time) from the total value of the sales sum values. When the latter display embodiment is adopted, since the monetary amount that may be used for applying to the event may be directly checked, the user-friendliness may be improved. 
     In addition, as shown in  FIG. 24 , the application status screen includes a button n 8  for commanding the re-acquisition of the additional information. When the CPU  11  of the portable terminal  8  receives the operation of the button n 8 , the electronic receipt management server  9  is commanded to perform re-acquisition of the application status information by transmitting the event ID of the event which the customer asked to participate in and the member code to the electronic receipt management server  9 . In this case, the CPU  51  of the electronic receipt management server  9  reads out the electronic receipt information and the application status information, which correspond to a combination of the event ID and the member code received from the portable terminal  8 , from the storage unit  53  and transmits the electronic receipt information and the application status information to the portable terminal  8 . Furthermore, the CPU  11  of the portable terminal  8  updates and displays the application status screen described above on the basis of the received electronic receipt information and application status information. Accordingly, for example, when new electronic receipt information relating to an event is added to the electronic receipt management server  9 , the sales sum monetary amount of the electronic receipt information is reflected in the total n 7  of the application status screen. 
     In addition, as shown in  FIG. 24 , the application status screen includes a button n 9  for requesting an application to attend an event. When the CPU  11  of the portable terminal  8  receives the operation of the button n 9  (Yes in step S 88 ), an application to attend the event is performed by transmitting the application information, which includes the event ID of the event and the member code, to the electronic receipt management server  9  (step S 89 ), and the process ends. In addition, when application to an event is not requested due to the operation or the like of another button (No in step S 88 ), the process ends. Furthermore, when the value of the total n 7  does not fulfill the usage conditions (for example, US$10), the CPU  11  of the portable terminal  8  may prevent the button n 9  from being unintentionally operated by disabling the button n 9 . 
     Meanwhile, when the CPU  51  of the electronic receipt management server  9  receives the application information from the portable terminal  8 , the CPU  51  increments by 1 the application times in the application status information, which is specified by the application information (the event ID and the member code), and completes the application reception. In addition, each time the CPU  51  of the electronic receipt management server  9  receives new electronic receipt information (and additional information) from the electronic receipt server  6 , the CPU  51  determines whether or not the combination of the store code and the member code, which are included in the electronic receipt information, corresponds to the management target of the application status information. Furthermore, when the combination corresponds to the management target, the CPU  51  associates and manages the received electronic receipt and the application status information. 
     Furthermore, when display control of the total n 7  is not performed in the portable terminal  8  to subtract a monetary amount according to the application times, the CPU  51  of the electronic receipt management server  9  may perform control such that a monetary amount according to the application times is subtracted from the total value of the sales sum values in the electronic receipt information that is concerned. For the control, for example, command information, which commands that a monetary amount according to the application times be subtracted from the total value of the sales sum values in the electronic receipt information, may also be added to the additional information and transmitted. 
     In addition, an embodiment may also be adopted in which the member code or the like is transmitted to an external site relating to the event from the electronic receipt management server  9  in accordance with the completion of the application reception. In addition, when a lottery or the like is performed within a shopping center, application completion information (for example, a two-dimensional bar-code or the like) indicating that the application reception is complete may also be transmitted to the portable terminal  8 . In this case, for example, as shown in a display example N 5  of  FIG. 25 , the CPU  11  of the portable terminal  8  displays the application completion information (a two-dimensional code n 10 ), which is transmitted from the electronic receipt management server  9 , on the display unit  17 . Accordingly, at the administration side of the event, application history to the event may be easily confirmed by reading the two-dimensional code n 10 , which is displayed on the display unit  17 , using a code scanner. 
     In this manner, according to the electronic receipt system of the modification example, since, unlike the electronic receipt (and the additional information) system sent by or dedicated to individual companies of the related art, the electronic receipt system may be implemented to go beyond the company scope, the introduction of the electronic receipts may be promoted. 
     In addition, as in the modification example described above, since the additional information may be provided and received in units of an aggregate body such as a shopping center including a plurality of the stores  1 , the introduction of the electronic receipts may be promoted, and sales may be promoted, in units of the aggregate body. In addition, in the modification example described above, since a fractional portion of the sales sum values, the individual payments of which do not satisfy the application conditions, may be effectively used by inheriting the payment content (the sales sum values) in each store  1  as the total value, the user-friendliness may be improved. 
     Furthermore, in the modification example described above, an embodiment is adopted in which the CPU  11  of the portable terminal  8  performs the calculation of the total value and the like. However, the embodiment is not limited thereto, and the CPU  51  of the electronic receipt management server  9  may also calculate the total value and the like. In addition, an embodiment may also be adopted in which the screen configuration of the participation confirmation screen and the like is provided to the portable terminal  8  by the electronic receipt management server  9 . 
     In addition, in the modification example described above, description is given using the shopping center as an example. However, the embodiment is not limited thereto and an aggregate body such as a shopping district may also be the target. In addition, in the modification example described above, an embodiment is adopted in which the application is performed in two stages of the participation and the application with respect to the event. However, the present disclosure is not limited to the embodiment, and the application status confirmation screen of  FIG. 24  may also be displayed after selecting the event (the event information) in  FIG. 21 .
