Description

  Embodiments described herein relate generally to a product code reader and a program.

  Conventionally, at a retail store such as a supermarket, various card media such as a credit card and a point card are used for settlement. For example, in a store where a credit card can be used for credit settlement, a customer is allowed to select cash payment or credit card payment as a payment method for a product price. In such a store, when credit payment is selected by a customer, various information (credit information) is read from the credit card of the customer using a card reader capable of reading credit card data, and credit payment is performed. Credit settlement is performed by making a credit inquiry to a credit inquiry organization using a mobile terminal (CAT terminal).

  Further, at a store that issues a point card, points are given according to the price of a product purchased by a customer, and managed in association with identification information (member identification information) for identifying the customer. This member identification information is generally written and stored on the point card itself, and the customer's member identification information is specified by reading the point card presented by the customer with a card reader.

  In addition, regarding the reading of a barcode attached to a product, a technique is known in which a barcode portion attached to a product is imaged using an image sensor such as a CCD, and the product code is read from the captured image.

  However, the conventional technology relating to reading of a card medium requires a card reading device for reading information from the card medium, and this card reading device has a configuration for reading a product code from a barcode (for example, an imaging device). Therefore, there is a problem that the apparatus configuration and the reading operation become complicated.

  The product code reading apparatus according to the embodiment includes an image capturing unit, a code symbol detecting unit, a code reading unit, and a card information reading unit. The image capturing unit captures an image captured by the imaging unit. The code symbol detection unit detects a code symbol attached to the product to be purchased from the image captured by the image capture unit. The code reading means reads code information held in the code symbol from the code symbol detected by the code symbol detecting means. The card information reading unit reads the card information attached to the card medium possessed by the customer who purchases the product from the image captured by the image capturing unit.

  Here, the credit inquiry organization 300 is a credit card company that issues a credit card, an agency that performs agency of credit settlement, or the like. The credit inquiry organization 300 checks the validity period of the credit card, the past use history, the presence or absence of trouble, etc. based on the credit information described later, and makes a credit inquiry to confirm whether or not the credit card can be settled.

  Next, a characteristic function unit included in the product code reading apparatus 200 will be described. The CPU 211 cooperates with the program stored in the ROM 212 and the storage unit 216, as shown in FIG. 2, the image data capturing unit 221, the code reading unit 222, the card reading unit 223, the credit settlement unit 224, and the information output. The unit 225 is realized.

  The image data capturing unit 221 causes the imaging unit 215 to start an imaging operation by outputting an imaging on signal to the imaging unit 215. The image data capturing unit 221 captures image data captured by the image capturing unit 215 and stores it in the RAM 213.

  The code reading unit 222 detects a barcode image attached to the product from the image data stored in the RAM 213 by the image data capturing unit 221 and performs a barcode reading process of reading the product code from the detected barcode. Specifically, the code reading unit 222 binarizes one frame of image data stored in the RAM 213 and detects whether or not a data area related to a barcode exists in the binarized data. When the code reading unit 222 detects a data area related to the barcode, the code reading unit 222 decodes the barcode and reads the decoded data as a product code of the product G. The code reading unit 222 stores the read product code in the RAM 213.

  The card reading unit 223 detects the image of the point card from the image data stored in the RAM 213 by the image data capturing unit 221 and reads the member identification information displayed on the point card as the card information of the point card The card reading process is executed.

  Specifically, the card reading unit 223 recognizes a character string, a design, and a layout included in an image, and compares them with a template file 216b prepared for detecting a point card, whereby one frame stored in the RAM 213 is stored. It is detected whether the point card image is included in the image data. When the card reading unit 223 detects a point card image, the card reading unit 223 reads a character string represented at a predetermined position of the point card as member identification information. Then, the card reading unit 223 stores the read member identification information in the RAM 213.

  For example, when the point card C1 shown in FIG. 4 is imaged, the card reading unit 223 points in the image data from the character string (TEC super) and design included in the point card C1, and the layout of the entire point card C1. It is detected that the image of the card C1 is included. Then, the card reading unit 223 reads the member identification information represented at a predetermined position (broken line portion) of the point card C1. The specified position may be specified based on a character string (such as “Member No.”) included in the point card C1, or may be determined based on layout information defined in the template file 216b. Good.

  Further, when the credit reading start is instructed from the POS terminal 100, the card reading unit 223 detects the image of the credit card from the image data stored in the RAM 213 by the image data capturing unit 221, and the credit card receives the credit card image. A card information reading process for reading the credit information necessary for the credit settlement shown as the card information of the credit card is executed.

  Specifically, the card reading unit 223 recognizes a character string, a design, and a layout included in the image, and compares them with a template file 216b prepared for detecting a credit card, so that one frame stored in the RAM 213 is stored. It is detected whether or not a credit card image is included in the image data. When the card reading unit 223 detects an image of a credit card, the card reading unit 223 reads information such as a credit card number and an expiration date displayed at a predetermined position of the credit card as credit information. Then, the card reading unit 223 stores the read credit information in the RAM 213.

  For example, when the credit card C2 shown in FIG. 5 is imaged, the card reading unit 223 includes the character string (YY credit card) and design included in the credit card C2 and the layout of the entire credit card C2 in the image data. It is detected that an image of the credit card C2 is included. Then, the card reading unit 223 reads card information represented at a predetermined position (broken line portion) of the credit card C2.

  In FIG. 5, a broken line area A11 means a position where a character string or a logo mark indicating the issuing company of the credit card C2 is represented, and information indicating the issuing company is read from the broken line area A11. The broken line area A12 means a position where the credit card number is represented, and the credit card number is read from the broken line area A12. The broken line area A13 means a position where the expiration date of the credit card C2 is represented, and the expiration date (month / year) is read from the broken line area A13. The broken line area A14 means a position where the name of the owner of the credit card C2 is represented, and the name is read from the broken line area A14. The card reading unit 223 stores information read from each broken line area in the RAM 213 as credit information. Each broken line area may be specified based on a character string (such as “expiration date”) included in the credit card C2 or based on layout information defined in the template file 216b. Good.

  Moreover, it is good also as a form which reads not only the information shown on the surface of the credit card C2, but the information shown on the back surface of the said credit card C2. For example, as shown in FIG. 6, the signature (dashed line area A15) of the owner of the credit card C2 shown on the back surface of the credit card C2 may be read as image data and included in the credit information.

  Returning to FIG. 2, the credit settlement unit 224 is a functional unit that performs credit settlement by communicating with the credit inquiry organization 300 via the second communication I / F 217. Specifically, the credit settlement unit 224 transmits the credit information read by the card reading unit 223 together with the settlement amount to the credit inquiry organization 300, thereby obtaining a credit result indicating whether or not the credit card can be settled. Received from the inquiry organization 300. When the credit result indicates that payment is not possible, the credit payment unit 224 transmits a signal indicating that payment is not possible to the POS terminal 100 via the first communication I / F 214. In addition, when the credit result indicates that payment is possible, the credit settlement unit 224, when performing credit settlement, sends a signal indicating completion of settlement together with the first settlement I / F 214 together with the credit settlement data necessary for receipt output for credit payment. To the POS terminal 100.

  The information output unit 225 transmits (outputs) the product code read by the code reading unit 222 to the POS terminal 100 via the first communication I / F 214. The information output unit 225 transmits (outputs) the member identification information read by the card reading unit 223 to the POS terminal 100 via the first communication I / F 214.

  The operation of the checkout system of this embodiment will be described below with reference to FIGS. Here, FIG. 7 is a flowchart showing the procedure of the payment process performed by the POS terminal 100.

  First, the CPU 111 of the POS terminal 100 transmits a signal instructing the start of transaction to the commodity code reading device 200 in response to a predetermined key operation on the keyboard 101 (step S11). Thereby, the product code reading apparatus 200 starts an information output process described later.

  Subsequently, the settlement processing unit 121 determines whether or not a product code is input from the product code reading device 200 (step S12). Here, when the input of the product code is accepted (step S12; Yes), the settlement processing unit 121 reads a record corresponding to the product code from the PLU file 114b (step S13). Next, the settlement processing unit 121 performs sales registration based on the record read in step S13 and the number of sales of the product (step S14), and proceeds to step S17. The settlement processing unit 121 displays and outputs the points calculated by the point calculation unit 122 by displaying the contents registered for sale on the display unit 102 and the display unit 103.

  If no product code is input in step S12, the point calculation unit 122 determines whether member identification information is input from the product code reading device 200 (step S15). Here, if the input of member identification information is received (step S15; Yes), the point calculation part 122 will store this member identification information in RAM113 (step S16), and will transfer to step S17. If member identification information is not input in step S15, the process immediately proceeds to step S17.

  In step S <b> 17, the CPU 111 determines whether or not input of key information representing a “tightening” key has been received from the keyboard 101 (step S <b> 17). If the input of the “tightening” key cannot be confirmed (step S17; No), the process returns to step S12 again. In step S17, when the input of the “tightening” key is received (step S17; Yes), the CPU 111 transmits a signal instructing the end of the transaction to the commodity code reading device 200 via the communication I / F 115 (step S18). ).

  Subsequently, when the payment processing unit 121 calculates the total amount of each product registered for sale (step S19), the payment processing unit 121 determines whether the payment method of the total amount is payment by cash or payment by credit card (step S20). . The payment method is specified by the operator of the POS terminal 100 via the keyboard 101.

  In the case of payment by cash (step S20; Yes), the settlement processing unit 121 waits until cash payment is completed (step S21; No), and confirms the completion of payment (step S21; Yes). The recorded cash payment receipt is output from the printer 104 (step S22), and the process proceeds to step S27.

  On the other hand, in the case of payment by credit card (step S20; No), the settlement processing unit 121 uses the total amount calculated in step S19 together with a signal for instructing the start of credit settlement via the communication I / F 115 to the product code reading device 200. (Step S23). As a result, the merchandise code reading apparatus 200 starts a credit settlement process described later.

  Subsequently, when the payment processing unit 121 receives a signal instructing completion of payment from the product code reading device 200 (step S24; Yes), a payment payment receipt is received based on the credit payment data transmitted together with this signal. The data is output from the printer 104 (step S25), and the process proceeds to step S27. When a signal instructing that payment is not possible is received from the product code reading device 200 (step S24; No), a message indicating that payment is not possible is displayed on the operator display 102 (step S26). Exit.

  In step S27, when member identification information is stored in the RAM 113, the point calculation unit 122 calculates a point corresponding to the total amount and adds it to the accumulated point of the member master file 114c corresponding to this member identification information ( Step S27), the process is terminated.

  Next, the information output process of the product code reading apparatus 200 will be described with reference to FIG. Here, FIG. 8 is a flowchart showing a procedure of information output processing performed by the product code reading apparatus 200.

  When the transaction start is instructed by a signal from the POS terminal 100, the CPU 211 of the commodity code reading device 200 starts an information output process. The image data capturing unit 221 outputs an imaging on signal to the imaging unit 215, and starts an imaging operation by the imaging unit 215 (step S31). The image data capturing unit 221 captures the image data captured by the image capturing unit 215 into the RAM 213 (step S32). Then, when the barcode reading process described above is started (step S33), the code reading unit 222 determines whether or not a barcode is detected from the image data (step S34). Here, when the code reading unit 222 detects a barcode, the information output unit 225 outputs the product code stored in the RAM 213 to the POS terminal 100 via the first communication I / F 214 (step S35). Control goes to step S39. If the sales quantity is input via the keyboard 202, the sales quantity is output together with the product code.

  On the other hand, when the barcode is not detected in step S34 (step S34; No), the card reading unit 223 starts the point card reading process (step S36), and whether or not the point card image is detected from the image data. Is determined (step S37). Here, when the card reading unit 223 detects the image of the point card (step S37; Yes), the information output unit 225 uses the member identification information read by the card reading unit 223 from the predetermined position of the image as the first. The data is output to the POS terminal 100 via the communication I / F 214 (step S38), and the process proceeds to step S39. If no point card image is detected (step S37; No), the process immediately proceeds to step S39.

  In step S39, the CPU 211 determines whether or not a transaction end is instructed by a signal from the POS terminal 100 (step S39). When the transaction end is not instructed (step S39; No), the process returns to step S32 again, and steps S32 to S39 are repeatedly executed until the transaction end is instructed. When the transaction end is instructed (step S39; Yes), the image data capturing unit 221 outputs an imaging off signal to the imaging unit 215 (step S40), and stops the imaging operation by the imaging unit 215.

  Next, with reference to FIG. 9, the credit settlement process of the product code reading apparatus 200 will be described. Here, FIG. 9 is a flowchart showing a procedure of credit settlement processing performed by the product code reading device 200.

  When the CPU 211 of the product code reading apparatus 200 is instructed to start credit settlement by a signal from the POS terminal 100, it starts credit settlement processing. In the credit settlement process, the image data capturing unit 221 outputs an imaging on signal to the imaging unit 215, and starts an imaging operation by the imaging unit 215 (step S51). The image data capturing unit 221 captures the image data captured by the imaging unit 215 into the RAM 213 (step S52).

  Subsequently, the card reading unit 223 starts a credit card reading process (step S53), and determines whether a credit card image is detected from the image data (step S54). Here, when detecting the image of the credit card, the card reading unit 223 reads the credit information from a predetermined position of the image and determines whether or not the signature needs to be read (step S55). Here, the case where it is necessary to read the signature is a case where the total amount transmitted from the POS terminal 100 at the start of credit settlement exceeds a predetermined amount.

  If it is determined that reading of the signature is unnecessary (step S55; No), the process immediately proceeds to step S58. If it is determined that the signature needs to be read (step S55; Yes), the card reading unit 223 displays a message indicating that the signature needs to be input on the operator display 203 (step S56). Wait until reading is complete (step S57; No).

  Here, FIG. 10 is a diagram illustrating an example of the display screen displayed in step S56. The figure shows an example in which “Please capture the signature” is displayed on the display 203 as a message indicating that the signature needs to be input. In addition, an image captured by the imaging unit 215 is displayed in the area A2 below the message. Here, the reading of the signature may be in the form of reading the signature shown on the back side of the credit card as shown in the area A2 in FIG. 10 or in the form of reading the signature written on a predetermined sheet. When reading the signature on the back of the credit card, it is preferable to display a message such as “Turn the credit card over” on the display 203.

  Returning to FIG. 9, when the card reading unit 223 completes reading of the signature (step S57; Yes), the credit settlement unit 224 transmits the credit information read by the card reading unit 223 and the POS terminal 100 as the settlement amount. The total amount thus transmitted is transmitted to the credit inquiry organization 300 via the second communication I / F 217, and the credit inquiry is executed (step S58).

  Next, the credit settlement unit 224 determines whether credit settlement is possible based on the credit result returned from the credit inquiry organization 300 (step S59). Here, when the credit result indicates that payment is not possible (step S59; No), the credit payment unit 224 displays a message indicating that payment is not possible on the operator display 203 (step S60), and payment is not possible. A signal indicating the possibility is output to the POS terminal 100 via the first communication I / F 214 (step S61), and the process proceeds to step S64.

  On the other hand, when the credit result indicates that payment is possible (step S59; Yes), the credit settlement unit 224 performs settlement processing for the settlement price with the credit inquiry organization 300 (step S62), and the settlement indicating the contents of the settlement. The information is output to the POS terminal 100 via the first communication I / F 214 together with a signal indicating that the payment is completed (step S63), and the process proceeds to step S64.

  Subsequently, the credit settlement unit 224 deletes the credit information read from the credit card from the RAM 213, thereby preventing leakage of a credit number or the like (step S64). Then, the image data capturing unit 221 outputs an imaging off signal to the imaging unit 215, thereby stopping the imaging operation by the imaging unit 215 (step S65), and ends this process.

  As described above, according to the present embodiment, the card information indicated on the card medium is read from the card medium such as a point card or credit card imaged by the imaging unit 215, and the point information is based on the card information. Perform grants and credit settlements. This eliminates the need to install a reader device that reads point cards and credit cards, thereby simplifying the device configuration of the product code reading device 200 and improving the efficiency of operations related to reading card information. it can.

  Furthermore, according to the present embodiment, since the product code reading apparatus 200 can perform credit settlement, the load on the POS terminal 100 can be reduced. As a result, the processing performed by the POS terminal 100 and the product code reading device 200 can be separated, and the efficiency of the settlement processing can be improved.

  The embodiment of the present invention has been described above, but the present invention is not limited to this, and various modifications, substitutions, additions, and the like are possible without departing from the spirit of the present invention.

  For example, in the above embodiment, the PLU file 114b and the member master file 114c are stored in the POS terminal 100. However, the present invention is not limited to this, and these files are stored in an external device accessible by the POS terminal 100. It is good also as a form to do.

  In addition, the program executed by the POS terminal 100 and the product code reading apparatus 200 of the above-described embodiment can be installed in a file in an installable format or an executable format, such as a CD-ROM, a flexible disk (FD), a CD-R, a DVD ( The recording medium may be recorded on a computer-readable recording medium such as a digital versatile disk).

  In addition, the program executed by the POS terminal 100 and the product code reading device 200 of the above embodiment is stored on a computer connected to a network such as the Internet and is provided by being downloaded via the network. Also good. Further, the program executed by the POS terminal 100 and the product code reading device 200 of the above embodiment may be configured to be provided or distributed via a network such as the Internet.
