(Operation when purchasing a product)
Next, an operation when a customer (user) purchases a product using the electronic receipt system 1 will be described with reference to the flowcharts of FIGS. It is assumed that the user and the store to be processed are registered as members in the user DB 241 and the store DB 242 in advance. It is assumed that an appropriate coupon is registered in the coupon DB 243.

First, the customer (user) hands over the product to the store clerk and informs the customer that he / she purchases the product from his / her mobile terminal 30 using a coupon. At this time, the customer does not need to perform an operation for selecting a coupon to be used.
The store clerk who is informed that the product is to be purchased using the coupon tells the customer that the portable terminal 30 is brought close to the code reading unit 16 of the store terminal 10. The customer brings the mobile terminal 30 close to the code reading unit 16 of the store terminal 10, and non-contact communication is started between the store terminal 10 and the mobile terminal 30. And the portable terminal 30 transmits the carrier wave containing the user ID of the customer (user) who is an owner (step S11).

  The non-contact communication unit 11 of the store terminal 10 receives the carrier wave transmitted from the mobile terminal 30, demodulates the received carrier wave, and acquires the user ID (step S21). The control unit 17 of the store terminal 10 controls the communication unit 12 to transmit a coupon acquisition request including the received user ID and a store ID preset in the store terminal 10 to the management server 20 (step S22). ).

  When the communication unit 21 receives a coupon acquisition request from the store terminal 10, the control unit 25 of the management server 20 searches the databases 241 to 243 in the storage unit 24 and specifies a coupon to be used (step S <b> 31).

  Specifically, the control unit 25 detects user information having a user ID included in the coupon acquisition request from the user DB 241, and a coupon (user possessed coupon) held by the user (purchaser) from the detected user information. Is identified. Subsequently, the control unit 25 detects store information having the store ID included in the coupon acquisition request from the store DB 242 and specifies a coupon (store available coupon) that can be used at the purchase store from the detected store information. And control part 25 should just specify the coupon as a coupon used this time, when a user possession coupon is contained in a store useable coupon.

  Then, the control part 25 of the management server 20 detects the coupon information of the coupon specified by step S31 from coupon DB243, controls the communication part 21, and transmits to the shop terminal 10 which is a transmission source of a coupon acquisition request. (Step S32).

  When the store terminal 10 receives the coupon information from the management server 20, a message to that effect is displayed on the display unit 14. After confirming this display, the store clerk causes the code reading unit 16 of the store terminal 10 to read the barcode of the product purchased by the customer. When the code reading unit 16 reads the barcode of the product, the control unit 17 of the store terminal 10 performs an accounting process (step S23). Specifically, the control unit 17 of the store terminal 10 reads product data (product name and unit price) from the product master file for the product specified by the product code read by the code reading unit 16 from the barcode. And the control part 17 produces | generates the sales data which show the purchase content at the time of purchasing goods using a coupon based on the read merchandise data and the discount information which the acquired coupon information shows, and memory | storage part 15 stores. Note that the control unit 17 may periodically transmit the accumulated sales data to an external accounting server (not shown) or the like by batch processing or the like.

  Subsequently, the control unit 17 of the store terminal 10 controls the communication unit 12 to receive the sales data created by the accounting process in step S23, its own store ID, and the user ID acquired in step S21. The request is transmitted to the management server 20 (step S24).

  When receiving the receipt request, the control unit 25 of the management server 20 detects the user information having the user ID included in the receipt request from the user DB 241 and records the contents of the sales data in the purchase history of the detected user information (append) (FIG. 9, step S33).

  Subsequently, the control unit 25 of the management server 20 detects store information having the store ID included in the receipt request from the store DB 242, and acquires receipt template data and advertisement information from the detected store information (step S34).

  Subsequently, the control unit 25 detects a coupon that matches the distribution condition from the coupon DB 243 and registers it as a purchaser's possessed coupon (step S35).

Specifically, first, the control unit 25 detects, from the coupon DB 243, a coupon for which a delivery timing that matches the content of sales data included in the received receipt request is set. For example, when the sales data included in the receipt request indicates that the product a has been purchased for 1,000 yen at the store A, the control unit 25 selects “deliver when purchasing at the store A”, “when purchasing the product a” Coupons having distribution timings such as “distribution” and “distribution upon purchase of 1000 yen or more” are detected from the coupon DB 243.
Subsequently, the control unit 25 detects the user information having the user ID included in the receipt request from the user DB 241 and detects the user information based on the user attributes (gender, age, etc.) indicated by the detected user information and the purchase history. Narrow down the coupons that satisfy the delivery conditions from among the coupons. And the control part 25 should just register the coupon ID of the narrowed down coupon in the possession coupon of the detected user information.

  Subsequently, the control unit 25 controls the communication unit 21 to obtain the receipt template data and advertisement information acquired in step S34, the sales data included in the received receipt request, and the coupon information of the coupon registered in step S35. It transmits to the portable terminal 30 of the user who is a purchaser (step S36). In addition, what is necessary is just to acquire the destination to the portable terminal 30 from the mail address contained in the user information which has the user ID contained in the receipt request. Further, the transmission process to the portable terminal 30 in step S36 may be performed by another server (not shown) that performs push type information distribution.

  Subsequently, the mobile terminal 30 stores the received coupon information in its own hard disk or the like (step S12).

  Subsequently, the mobile terminal 30 creates receipt display image data (receipt image data) based on the received receipt template data, advertisement information, and sales data (step S13). And the portable terminal 30 displays a receipt image on a liquid crystal display based on the produced receipt image data (step S14). By confirming this display, the user can confirm what he / she purchased without confirming the paper receipt. In addition, since an advertisement corresponding to the purchase store is displayed on the receipt image, an advertising effect on the user can be expected. This completes the process for purchasing the product.

(Coupon delivery process)
In the above process, the coupon is distributed to the mobile terminal 30 when purchasing the product at the customer's store. However, in the present system, by appropriately setting the distribution timing of the coupon information stored in the coupon DB 243, it is possible to distribute the coupon not only at the time of product purchase but also at an arbitrary timing. Hereinafter, a coupon distribution process for distributing a coupon at an arbitrary timing will be described.

  For example, the control unit 25 of the management server 20 executes the coupon distribution process shown in the flowchart of FIG. 10 at a fixed time every day.

  First, the control unit 25 of the management server 20 refers to the coupon DB 243 and detects coupon information of a coupon whose distribution timing is today (step S41). For example, when today is August 1st, the control unit 25 detects coupon information whose delivery timing is set to “August 1 delivery”, “Monthly delivery”, or the like. In addition, when a user whose birthday is today is registered in the user DB 241, the control unit 25 may detect coupon information whose delivery timing is set to “birthday delivery”.

  Then, the control part 25 selects one from the coupon information detected by step S41 (step S42). And the control part 25 acquires the user information of the user who matches the delivery conditions which the selected coupon information shows from user DB241 (step S43).

  Subsequently, the control unit 25 registers the coupon ID of the coupon selected in Step S42 in the user-owned coupon indicated by the acquired user information (Step S44). And the control part 25 transmits the coupon information addressed to the user's email address indicated by the acquired user information (step S45).

  Subsequently, the control unit 25 determines whether or not a series of processing from step S42 to step S45 has been performed on all coupon information detected in step S41 (step S46).

  When the processing is not performed for all the detected coupon information (step S46; No), the control unit 25 selects unprocessed coupon information and distributes the coupon to the user who matches the conditions. The process of step S45 is repeated.

  When the process is performed on all detected coupon information (step S46; Yes), the coupon distribution process ends.

  Thus, according to the present invention, the user can use an optimal coupon by simply causing the store terminal 10 to read the mobile terminal 30 without selecting a coupon to be used at the time of purchase of the product.

  Further, according to the present invention, it is possible to distribute an optimal coupon that matches a condition such as a user attribute to the user at an optimal timing. Moreover, when distributing a coupon, not only a coupon is registered into the user information in user DB241 of the management server 20, but coupon information is transmitted to a user's portable terminal 30. FIG. Therefore, the user can confirm the coupons held without accessing the management server 20 only by confirming the coupon information stored in the mobile terminal 30.

(Modification)
The above embodiment can be variously modified and applied.

  For example, in the above embodiment, the coupon is distributed to the mobile terminal 30 of the customer. However, not only the coupon but also campaign information (for example, the URL of the campaign site) or an advertisement for guiding to a specific campaign site is distributed. Often, an arbitrary service may be distributed in the process at the time of product purchase at a store and the coupon distribution process.

  In the above-described embodiment, the electronic receipt is transmitted to the customer's mobile terminal 30 close to the store terminal 10 at the time of purchase at the store, but the electronic receipt is also transmitted to the customer's home PC (Personal Computer) or the like. May be. In this case, it is necessary to set the mail address of the home PC as the mail address of the customer user information.

  In addition, the store terminal 10 and the management server 20 store an encryption key and a decryption key corresponding to the encryption key. And in the flowchart of FIG. 8, you may make it encrypt and transmit the information transmitted / received between the shop terminal 10 and the management server 20. FIG. By doing in this way, it becomes possible to improve security more.

Moreover, in the said embodiment, the customer used the coupon by making the store terminal 10 read the portable terminal 30. FIG. However, the coupon may be made available by causing the store terminal 10 to read an IC card such as a credit card or a point card that allows the customer to perform non-contact communication. By doing in this way, the customer who forgot to have the portable terminal 30 can use the coupon in the same manner, and the convenience can be further improved.
In this case, a card ID (credit number or the like) that can uniquely identify the user stored in the IC card needs to be held in the user information in the user DB 241. And the shop terminal 10 transmits the coupon acquisition request | requirement containing the card ID read from the customer's IC card to the management server 20 at the time of goods purchase. Then, the management server 20 detects the user information having the card ID included in the received coupon acquisition request, and specifies the coupon to be used, the electronic receipt issuance destination, and the like from the user information, as in the above-described processing. That's fine.

  Moreover, in the said embodiment, the management server 20 transmitted the information for electronic coupon display to the portable terminal 30 (FIG. 9, step S36), and the portable terminal 30 produced receipt image data from this information (step S13). However, the management server 20 may create receipt image data and transmit the created receipt image data to the mobile terminal 30.

Further, for example, the store terminal 10 and the management server 20 of the present invention are not limited to dedicated hardware, and can be realized by a normal computer system.
Specifically, in each of the above-described embodiments, the programs of the store terminal 10 and the management server 20 have been described as being stored in advance in the storage units 15 and 24 and the like. However, a program for executing the above-described processing operation is recorded on a computer-readable recording medium such as a flexible disk, a CD-ROM (Compact Disk Read-Only Memory), a DVD (Digital Versatile Disk), or an MO (Magneto-Optical disk). You may comprise the store terminal 10 and the management server 20 which perform the above-mentioned process by storing in a medium, distributing, and installing the program in a computer.

Further, the program may be stored in a disk device or the like included in a server device on a communication network such as the Internet, and may be downloaded to a computer by being superimposed on a carrier wave, for example. Furthermore, the processing of the store terminal 10 and the management server 20 described above can also be achieved by starting and executing the program while transferring it via the communication network.
When the above functions are realized by an OS (Operating System) sharing or by cooperation between the OS and an application, only the part other than the OS may be stored in a medium and distributed. You may download it.
