Description

  The present invention relates to a receipt issuing device that issues a receipt for payment of a purchaser.

  As a method of managing service points obtained by purchase, the store that issues service points has a system to manage service points, and every time a transaction with a purchaser occurs, a point corresponding to the transaction amount is calculated. The general method is to update the cumulative points of the buyer.

  However, with this method, the store bears a large burden in terms of capital investment and point management processing.

  Techniques for solving this burden have already been published in the patent literature. According to this technology, the store only issues a receipt from the POS cash register device, and the customer inputs the receipt number and amount printed on the receipt to the customer's own mobile phone and transmits it to the point management server device.

The point management server device searches for sales data that matches the received receipt number and amount from the POS server device connected to the POS cash register device, calculates the number of points related to the sales data, and registers it as the number of points of the customer (Patent Document 1).
JP 2002-298222 A

  However, since the customer himself inputs the receipt information, there arises a problem that the validity of the information presented by the customer must be verified.

  In order to verify the validity, in the above technique, the sales data stored in the POS server management apparatus is accessed and collated with the presentation information. However, if a store entrusts service point management only to a point management service company, access from other companies to a POS server management device that manages sales data, which is important information of the company, is a security or information confidentiality. From the viewpoint, there is a great sense of resistance for the store.

  In the above technology, when a customer logs in to the point management service from a mobile terminal, the access ID and password are entered to check whether or not the access is qualified. However, it cannot be proved that the purchase information printed on the receipt is the person who has logged in. Therefore, there is room for illegally using a picked-up receipt or a stolen receipt and registering it as one's own points.

  An object of the present invention is to omit the operation of the customer himself / herself to input purchase information, and to ensure that service points are registered to those who have actually purchased.

  The present invention is a receipt issuing device that issues a receipt for purchaser's price payment, receiving means for receiving input of purchaser's identification information, calculation means for calculating the price paid by the purchaser, Code information is generated based on the calculated price and the received user identification information, and is provided with issuing means for issuing the code information.

  Further, the accepting means of the present invention accepts user identification information by reading a bar code displayed on the screen by a purchaser terminal possessed by the purchaser, and the issuing means issues a two-dimensional barcode as the code information. It is characterized by that.

  Further, the issuing means of the present invention prints the code information on a receipt.

  According to the present invention, since a barcode is generated based on purchase information and customer identification information and printed on a receipt, it is possible to prevent an unauthorized point application because the purchaser is clearly indicated.

  In addition, since the customer reads the barcode printed on the receipt with the mobile terminal owned by the customer and automatically transmits the information to the point management device, the customer's input operation is not involved and the customer operation is simplified. Moreover, tampering can be prevented.

  Hereinafter, embodiments of the present invention will be described. It should be noted that any changes may be made to the present embodiment as long as the same effects as in the embodiment shown here are produced.

  A configuration of the entire system in the present invention is shown in FIG. The present invention includes a management device 100, a user terminal 200, a register 300 with a barcode reader, a network 400, and a store terminal 500.

  Next, with reference to FIG. 5, a receipt printing process performed by the register 300 with a barcode reader when a member settles a purchased product at a member store will be described.

  In S41, the reading unit 320 of the register 300 with the barcode reader reads the product barcode attached to the product, and identifies the data content indicated by the barcode. This product barcode includes product information such as a product name, product identification number, and price, and is equivalent to a normal product barcode.

  When a member settles a plurality of products, the product barcode is read a plurality of times.

  In S42, the reading unit 320 reads the member barcode displayed on the terminal screen by the user terminal 200, and identifies the member ID indicated by the barcode.

  In S <b> 43, the printing unit 310 of the register 300 with the barcode reader performs a product settlement process from the product information identified by the reading unit 320. In this checkout process, the price for each product is identified, tax and other necessary addition / subtraction processes are performed, the total amount is calculated, and then compared with the member's payment price to calculate change. This process is equivalent to the settlement process performed by a conventional register with a barcode reader.

  In step S44, the printing unit 310 uses the information for the settlement process, the product information, the member ID, the store ID issued from the management apparatus 100, the settlement process date and time, and the receipt ID for identifying the receipt as the data contents. Create a dimensional barcode.

  In S45, the printing unit 310 prints a receipt 1100 as shown in FIG. 12 on which a two-dimensional barcode is printed, and ends a series of receipt printing processes. The receipt 1100 is given to a member who possesses the user terminal 200 displaying the member barcode.

  Next, a point application process in which the reading unit 220 of the user terminal 200 reads the two-dimensional barcode issued by the member store and applies for points to the management apparatus 100 will be described with reference to FIG.

  The reading unit 220 is dedicated application software downloaded from the management apparatus 100 and is activated when a member inputs an operation from the user terminal 220 to execute a series of point application processes.

  Data exchange between the management apparatus 100 and the dedicated application software is processed via the Internet site of the point management service controlled by the management means 120 of the management apparatus 100.

  In S51, the reading unit 220 reads the two-dimensional barcode printed on the receipt 1100 using a barcode scanner built in the user terminal 200, and in S52, the amount information, the store ID indicated by the read two-dimensional barcode. , Identify the member ID, receipt ID, and settlement date.

  In S <b> 53, the reading unit 220 accesses a URL dedicated to point application in the Internet site of the point management service preset in the reading unit 220. This URL cannot be moved from the menu screen of the point management service normally accessed by the member, and the member does not know this URL.

  Since this URL is written in the program of the dedicated application software, the dedicated software automatically accesses. Alternatively, dedicated software may be set in advance to access a specific URL on the Internet site of the point management service, and the point application dedicated URL may be acquired there.

  In S54, the reading means 220 logs in using login identification number or password set in the program of the dedicated application software for login authentication required when accessing the point application dedicated URL.

  In S55, the reading unit 220 transmits the member ID, the store ID, the amount, the receipt ID, and the payment date / time data identified in S52 to the management unit 120 of the management apparatus 100 via the point application dedicated URL.

  In S <b> 56, the reading unit 220 receives the point update result information from the management unit 120 of the management apparatus 100 and displays it on the terminal screen of the user terminal 200.

  The point update result information includes the number of points generated this time and the point balance of the target member updated as a result.

  Then, in response to an operation input from the member, the reading unit 220 performs logout processing from the point application dedicated URL and also terminates the dedicated application software, and ends the series of point application processing.

  As described above, in the point application process, since the member does not know the URL dedicated for point application, the member cannot access the URL dedicated for point application by his / her operation input. Further, since the member ID and the purchase amount in the two-dimensional barcode are not displayed on the screen of the user terminal 200, they cannot be tampered with. Therefore, you cannot apply for points as your own points using the receipts of other members.

  A point registration process performed by the management unit 120 of the management apparatus 100 will be described with reference to FIG. The point registration processing means starts when the reading means 220 of the user terminal 200 accesses the point application dedicated URL on the Internet site of the point management service.

  In S61, after authenticating the login of the reading unit 220 of the user terminal 200, the management unit 120 receives the store ID, member ID, purchase amount, receipt ID, and settlement date data transmitted by the reading unit 220. .

  In S62, the management unit 120 refers to a point application history database (not shown) for the received data and checks whether the same data record has already been accumulated. If it is new data, a new record is created and the data received this time is recorded. If it has already been accumulated, the point application for this time has already been registered with the reading means 220 of the user terminal 200. Transmits registration refusal information indicating that it is not accepted.

  When the data received this time is recorded in the point application history DB, in S63, the management unit 120 refers to the point definition table 900 and calculates the number of points from the purchase amount received this time.

  For example, when a point application is made on the basis of a receipt as shown in FIG. 12 issued by a store with a store ID S01, the point definition table 900 defines that 100 points are issued for a purchase amount of 1000 yen at the store S01. Has been. Therefore, if the purchase price is 1700 yen, 100 service points for 1000 yen are issued.

  In S64, the management unit 120 identifies the member ID from the data received this time, and further identifies the record of the point table 1000 to which the current point balance should be updated by identifying the store ID in S65, In S66, the points are updated.

  For example, when a point application is made based on a receipt as shown in FIG. 12, in the point table 1000 in which the member ID is created for P01, the record with the store ID S01 is specified as the record to be changed this time. .

  If the current point application is the first member, there is no corresponding point table 1000. Therefore, a new point table 1000 dedicated to the member is created, and a new record of the store ID of the current application is stored in the point table 1000. Create and record the number of points calculated this time as the total number of points.

  If the target member's point table 1000 exists, but there is no corresponding store ID record, a new record corresponding to the currently applied store ID is created, and the number of points calculated this time is used as the total points. Record.

  If a record of the target member's point table 1000 and target store ID already exists, the record is changed to a value obtained by adding the number of points calculated this time to the value recorded in the number of points of the record.

  In step S <b> 67, the management unit 120 transmits point update result information to the reading unit 220 of the user terminal 200, and then receives a logout request from the point application-dedicated URL from the reading unit 220 and logs out. The process is performed, and the series of point registration processes is completed.

  The point update result information includes the number of points generated this time and the point balance of the target member updated as a result.

  The point registration process executed by the management unit 120 of the management apparatus 100 has been described above.

  In this embodiment, since point registration is a feature, it will not be described in detail. However, the management unit 120 also supports a point use application from the user terminal 200.

  When the user terminal 200 accesses the point use application URL in the Internet site of the point management service, the management unit 120 acquires the target store ID that the member desires to use the points. And the management means 120 transmits the list information regarding the point available service provided by the corresponding store ID to the user terminal 200. This point use service includes a discount service.

  When the selected service information is received from the user terminal 200, the point update process is performed on the specific record of the corresponding point table 1000, and the barcode information and the point update result information of the corresponding point use service are transmitted to the user terminal 200. .

  When the user terminal 200 wants to use the point use service, the barcode of the service is displayed on the screen of the user terminal 200 on the register 300 with barcode reader and is read by the barcode scanner of the register 300 with barcode reader. .

Further, in this embodiment, a registration information change process, a point inquiry process, and the like in response to a request from the user terminal 200 or the shop terminal 500 are also possible. These processes are possible by diverting a mechanism that has already been generally implemented.
