On the product shelf 4, photographs of a plurality of types of products are posted. Below each product photo, a price is displayed on the right side, and a two-dimensional code 40 that electronically represents the name and price of the product is displayed on the right side. Each is posted.

  The two-dimensional code 40 is, for example, a QR (Quick Response) code (registered trademark) or the like, and includes three positioning symbols 41a, 41b, and 41c in which squares of a specific ratio are combined as shown in FIG. For example, a plurality of square cells are arranged in a matrix between the positioning symbols 41a, 41b, and 41c. In the two-dimensional code 40, the name and price of the corresponding product depending on the distribution pattern of cells having a predetermined lightness (black in this example) and cells having a predetermined lightness or higher (white in this example) among a plurality of cells. Various information such as is expressed.

  In addition, watermark information is embedded in the two-dimensional code 40 in the present embodiment. The watermark information-containing two-dimensional code 40 is subjected to wavelet transform on the original image of the two-dimensional code to be decomposed into frequency components, and among the decomposed frequency components, the watermark information is applied to the oblique high frequency components. Embed. And it produces | generates by performing inverse wavelet transformation to the high frequency component of the diagonal direction in which watermark information was embedded, and frequency components other than the high frequency component of the diagonal direction among each decomposed frequency component, and reconstructing. In the two-dimensional code 40 generated in this way, watermark information can be extracted from a high-frequency component in an oblique direction extracted by performing wavelet transformation. On the other hand, in the copy of the two-dimensional code 40, since information other than the watermark information appears very strongly in the HH component, the watermark information cannot be extracted.

  When it is determined in the process of step S2 that purchase is not instructed (step S2; No), it is determined whether reading is instructed again by the operation of the operation unit 24 by the user (step S3). At this time, if reading is not instructed (step S3; No), the process returns to step S2.

  On the other hand, when the user detects a photograph of another product desired to be purchased and is instructed to read again the two-dimensional code 40 under the photograph in the process of step S3 (step S3; Yes) After reading the product name and price from the two-dimensional code 40 by the reading unit 23 (step S4), the process returns to the process of step S2.

  When it is determined that purchase is instructed in the process of step S2 (step S2; Yes), the total price of the product is obtained by adding the prices of the products read in the processes of steps S1 and S4 (step S2). S5).

  Subsequently, the control unit 26 displays a confirmation screen on the display unit 22 (step S6), and the order contents such as the product ordered on the confirmation screen, the delivery destination, and the delivery time by the operation of the operation unit 24 by the user. Is determined (step S7). At this time, if the order details are not confirmed (step S7; No), the process waits in a loop until the order details are confirmed.

  And when it determines with the content of goods confirmed in the process of step S7 (step S7; Yes), an authentication screen is displayed on the display part 22 (step S8), and authentication is performed by operation of the operation part 24 by a user. It is determined whether a password has been input on the screen (step S9). At this time, if the password is not input (step S9; No), the process waits in a loop until the password is input.

  If it is determined in step S9 that the password has been input (step S9; Yes), the ordered product such as the ordered product, the total price, the delivery destination, and the delivery time, and the password are entered. The data is transmitted from the communication unit 25 to the settlement server 3 via the network 5 (step S10).

  On the other hand, in the settlement server 3, the control unit 33 receives the commodities desired to be purchased, the total amount, order contents such as the delivery destination and delivery time, and the personal identification number in the communication unit 31 (step S11). Subsequently, the control unit 33 performs confirmation (authentication processing) that the PIN number received in the process of step S11 is stored in the storage unit 32 (step S12), and then the credit card number corresponding thereto. A procedure (settlement process) for paying the total amount of the ordered product is performed with the credit card specified from (Step S13 in FIG. 7). Further, the control unit 33 performs a procedure (delivery process) for delivering the ordered product at the delivery time confirmed by the delivery destination confirmed by the user (step S14).

  Thereafter, the control unit 33 transmits an order completion notification for notifying that the order of the product is completed from the communication unit 31 to the mobile communication terminal 2 via the network 5 (step S15).

  On the other hand, in the mobile communication terminal 2, the control unit 26 responds to the reception of the order completion notification by the communication unit 25 (step S16), and displays an order completion screen on the display unit 22 to place an order for the product. After notifying the user of completion (step S17), the product ordering process is terminated.

  As described above, in the product ordering system 1 according to the present embodiment, the control unit 26 of the mobile communication terminal 2 uses the two-dimensional code 40 of a desired product among the two-dimensional codes 40 posted on the product shelf 4. The price of the product is read by the reading unit 23. Thereafter, when an instruction to purchase a product is given by the operation of the operation unit 24 by the user, the total price of the product price read by the reading unit 23 is calculated. Then, by transmitting the calculated total amount from the communication unit 25 to the settlement server 3 via the network 5, the settlement server 3 is instructed to settle the total amount of the product. Thereby, since the mobile communication terminal 2 does not need to make a payment every time the two-dimensional code 40 is read, the payment using the two-dimensional code can be easily performed.
