[0007] (First embodiment) First, a POS terminal 10 according to a first embodiment of the present invention will be described with reference to Fig. 1. Fig. 1 is a system block diagram showing an example of an operational state of the POS terminal according to the first embodiment.

[0008] As shown in Fig. 1, a checkout system 5 including a plurality of POS terminals 10, a store server 80, and a point management server 90 is installed in a store. Each POS terminal 10 is connected to the store server 80 via a communication network such as a LAN (Local Area Network) 82. The store server 80 and the point management server 90 are also connected to each other via the Internet 84.

[0009] The POS terminal 10 performs registration processing and settlement processing for products purchased by customers. The POS terminal 10 also gives points to members of the store according to the purchase amount.

[0010] The store server 80 manages the operation of multiple POS terminals 10 installed in the store. The store server 80 also acquires payment information from each POS terminal 10. Furthermore, the store server 80 periodically distributes to each POS terminal 10 a product master file M1 (described later) that stores product information on products for sale in association with product codes.

[0011] The point management server 90 is generally installed outside the store and manages information such as points given to members.

[0012] (Explanation of the overall configuration of a POS terminal) Next, the overall configuration of the POS terminal 10 will be described with reference to Fig. 2. Fig. 2 is a diagram showing a schematic configuration of the POS terminal of the first embodiment. The POS terminal 10 includes a keyboard 11, a cashier-side display 12, a customer-side display 14, a card reader 15, a barcode reader 16, and a receipt printer 17. The POS terminal 10 is an example of a product sales data processing device in the present invention.

[0013] The keyboard 11 has multiple keys such as numeric keys, a clear key, a return key, a subtotal key, and a closing key. The numeric keys are a numeric keypad for inputting numeric values ​​such as product codes and amounts. The clear key is a key for canceling an operation when an error occurs. The return key is a key for canceling the current operation and returning to the previous screen. The subtotal key is a key for completing the product registration process for registering products and declaring the calculation of the total transaction amount. The closing key is a key pressed to confirm the input contents and perform the settlement process (accounting process).

[0014] The cashier's display 12 has a display device such as an LCD (Liquid Crystal Display) panel, and a touch panel 13 laminated on the surface of the display device. The cashier's display 12 displays to the cashier a screen corresponding to the processing status of the registration process, the settlement process, etc. The touch panel 13 detects the cashier's pressing of a screen or button displayed on the cashier's display 12, and controls the operation of the POS terminal 10 according to the position pressed.

[0015] The customer-side display 14 is composed of a display device such as an LCD panel, and is positioned with its display surface facing the customer to display the price of the registered goods, the discount amount, the total transaction amount, the total discount amount, etc.

[0016] The card reader 15 reads customer information, such as a membership number, registered on a store membership card held by the customer. The card reader 15 may further include a function for writing information onto the membership card, and may write the latest number of points of the member.

[0017] Furthermore, the POS terminal 10 includes a barcode reader 16 that reads code data stored in a barcode attached to a product from the barcode. The barcode reader 16 decodes a light receiving signal of the code data attached to the product, acquires the code data represented by the barcode (product code that identifies the product), and outputs the code data to the CPU 21 (see FIG. 3) of the POS terminal 10.

[0018] The receipt printer 17 prints and issues itemized slips and receipts to be handed over to customers.

[0019] (Explanation of the hardware configuration of the POS terminal) Next, the hardware configuration of the POS terminal 10 will be described with reference to Fig. 3. Fig. 3 is a hardware block diagram showing an example of the hardware configuration of the POS terminal. As shown in Fig. 3, the POS terminal 10 includes a control unit 20, a storage unit 24, a controller 25, and a communication control unit 26.

[0020] The control unit 20 has a typical computer configuration including a CPU (Central Processing Unit) 21, a ROM 22, and a RAM 23. The CPU 21 reads out various programs, data files, etc. stored in the ROM 22 and a storage unit 24 (described later), and loads them in the RAM 23. The CPU 21 operates according to the various programs, data files, etc. loaded in the RAM 23, and controls the entire POS terminal 10.

[0021] The control unit 20 is connected to a storage unit 24 , a controller 25 , and a communication control unit 26 via an internal bus 27 .

[0022] The storage unit 24 retains stored information even when the power is turned off. The storage unit 24 is, for example, a hard disk drive (HDD). Instead of the HDD, a non-volatile memory such as a flash memory may be provided. The storage unit 42 stores programs including a control program P1. The control program P1 is a program for implementing functions provided in the POS terminal 10.

[0023] The control program P1 may be provided by being pre-installed in the ROM 22. The control program P1 may be provided by being recorded in a computer-readable recording medium such as a CD-ROM, a flexible disk (FD), a CD-R, or a digital versatile disk (DVD) in a format that can be installed or executed by the control unit 20. The control program P1 may be provided by being stored on a computer connected to a network such as the Internet and downloaded via the network. The control program P1 may be provided or distributed via a network such as the Internet.

[0024] The storage unit 24 further stores a product master file M1. The product master file M1 is a master file that stores product information such as product names and unit prices in association with product codes. The product master file M1 is updated successively as the POS terminal 10 and the store server 80 communicate with each other.

[0025] In addition, the memory unit 24 stores a sales file in which product information relating to products purchased by customers is registered, but since this is not a characteristic component of this embodiment, illustrations and detailed explanations are omitted.

[0026] The controller 25 connects the control unit 20 to the input / output devices, namely the keyboard 11, the cashier display 12, the touch panel 13, the customer display 14, the card reader 15, the barcode reader 16, and the receipt printer 17. The functions of each of the input / output devices are as described above.

[0027] The communication control unit 26 controls communication with the store server 80 to input and output various information.

[0028] (Description of the functional configuration of a POS terminal) Next, the functional configuration of the POS terminal 10 will be described with reference to Fig. 4. Fig. 4 is a functional block diagram showing an example of the functional configuration of the POS terminal.

[0029] The control unit 20 (see Figure 3) of the POS terminal 10 deploys the control program P1 in the RAM 23 and runs it to realize, as functional units, a customer identification unit 30, a point acquisition unit 31, a code symbol reading unit 32, a product registration processing unit 33, a point calculation unit 34, a point update unit 37, and a payment processing unit 38 shown in Figure 4.

[0030] The customer identification unit 30 identifies at least the membership number (identification number) of a customer performing a transaction. Specifically, the customer identification unit 30 identifies the customer's membership number by reading customer information, such as the membership number, registered on a membership card held by the customer.

[0031] The point acquisition unit 31 acquires the current number of points of the customer identified by the customer identification unit 30 from the point management server 90.

[0032] The code symbol reading unit 32 reads a code symbol that is attached to a product and includes information that identifies the product. The code symbol is, for example, a barcode or a two-dimensional code. The code symbol reading unit 32 is an example of a reading unit in the present invention.

[0033] The product registration processing unit 33 registers products purchased by the customer and calculates the total price of the products. The product registration processing unit 33 is an example of a purchase price calculation unit in the present invention.

[0034] The point calculation unit 34 calculates the number of points related to the product purchased by the customer. The point calculation unit 34 includes a normal point calculation unit 35 and a special point calculation unit 36.

[0035] The regular point calculation unit 35 calculates regular points to be awarded per unit purchase amount (for example, 200 yen) based on the total amount (purchase amount) of the purchased products.

[0036] The special point calculation unit 36 ​​calculates the special points to be awarded based on the total purchase amount of the products, on the condition that a specific product is included in the purchased products.

[0037] The point updating unit 37 adds the regular points calculated by the regular point calculation unit 35 and the special points calculated by the special point calculation unit 36 ​​to the current number of points acquired by the point acquisition unit 31. The point updating unit 37 also adds a number of special points according to the total purchase amount of the products. The point updating unit 37 is an example of the point adding unit of the present invention.

[0038] The payment processing unit 38 performs a payment process to pay the purchase price based on the result registered by the product registration processing unit 33.

[0039] (Explanation of how points are calculated) Next, a method for calculating points given to a member will be described with reference to Fig. 5. Fig. 5 is a diagram for explaining a method for calculating regular points and special points.

[0040] Table Ta shown in Fig. 5 is a table showing rules for awarding regular points and special points. First, regular points are awarded at a rate of 1 point for every 200 yen spent, regardless of the product purchased.

[0041] In addition, when a specific product (for example, product A) is purchased, a special number of points is awarded according to the amount of the customer's purchase.

[0042] More specifically, if the purchase amount is between 1,000 and 2,000 yen, 2 special points are awarded for each item of product A purchased. If the purchase amount is between 2,001 and 3,000 yen, 3 special points are awarded for each item of product A purchased. If the purchase amount is 3,001 yen or more, 5 special points are awarded for each item of product A purchased. In this way, the number of special points awarded increases according to the total price of the items.

[0043] In the example of table Ta, special points are awarded only to product A, but in general, special points are awarded to a plurality of pre-set products.

[0044] Table Tb shown in FIG. 5 is a table showing an example of calculation of regular points and special points. For example, suppose that a purchase amount of a certain customer is 2400 yen. The customer also purchases two units of product A. In this case, regular points are awarded as 2400 / 200=12 points. Furthermore, since the customer purchased two units of product A, referring to table Ta, special points are awarded as 3 points x 2 units = 6 points. Therefore, a total of 18 points are awarded to the customer, which is 6 points more than if only regular points were awarded.

[0045] (Explanation of the process flow performed by the POS terminal) Next, the flow of processing performed by the POS terminal 10 will be described with reference to Fig. 6. Fig. 6 is a flow chart showing an example of the flow of processing performed by the POS terminal.

[0046] The customer identification unit 30 acquires the membership number registered on the customer's membership card read by the card reader 15 (step S10).

[0047] The point acquisition unit 31 acquires the current number of points of the customer from the point management server 90 (step S11).

[0048] The code symbol reading unit 32 reads the code symbol attached to the product (step S12).

[0049] The product registration processing unit 33 registers the product to be purchased by the customer by checking the product code registered in the code symbol read by the code symbol reading unit 32 against the product master file M1 (step S13).

[0050] The product registration processing unit 33 determines whether the registered product is a product related to special points, i.e., a specific product (step S14). If it is determined that the registered product is a specific product (step S14: Yes), the process proceeds to step S15. On the other hand, if it is not determined that the registered product is a specific product (step S14: No), the process proceeds to step S16.

[0051] If the answer to the question in step S14 is Yes, the special point calculation unit 36 ​​accumulates the number of specific commodities for each type of specific commodities (step S15).

[0052] Following step S15, or if the determination in step S14 is No, the regular point calculation unit 35 accumulates the purchase amount (step S16).

[0053] The product registration processing unit 33 determines whether product registration is complete (step S17). If it is determined that product registration is complete (step S17: Yes), the process proceeds to step S18. On the other hand, if it is determined that product registration is not complete (step S17: No), the process returns to step S12. Note that whether product registration is complete may be determined by, for example, pressing the subtotal key on the keyboard 11.

[0054] If the result of the determination in step S17 is Yes, the regular point calculation unit 35 calculates regular points (step S18). Specifically, the regular point calculation unit 35 calculates the number of regular points according to the purchase amount accumulated in step S16.

[0055] Next, the special point calculation unit 36 ​​calculates the special points (step S19). Specifically, the special point calculation unit 36 ​​calculates the number of special points according to the purchase amount accumulated in step S16 and the number of purchases of the specific product accumulated in step S15.

[0056] The point update unit 37 adds the regular points calculated in step S18 and the special points calculated in step S19 to the points held by the customer, and updates the number of points (step S20). The updated number of points is stored in the point management server 90.

[0057] The payment processing unit 38 performs the payment process (step S21). Then, the POS terminal 10 ends the process of FIG.

[0058] As described above, in the POS terminal 10 (product sales data processing device) of the first embodiment, the product registration processing unit 33 (purchase amount calculation unit) calculates the total amount of products purchased by a customer, and the point update unit 37 (point addition unit) adds special points according to the total amount for a specific product, on condition that the specific product is included in the purchased products. Therefore, by stimulating the customer's desire to purchase, it is possible to more effectively promote sales of the specific product and reduce inventory.

[0059] In addition, in the POS terminal 10 (product sales data processing device) of the first embodiment, the point update unit 37 (point addition unit) adds special points in addition to the regular points according to the total amount. Therefore, the customer can obtain more points than usual. This makes it possible to more effectively promote sales of specific products and reduce inventory.

[0060] In addition, in the POS terminal 10 (product sales data processing device) of the first embodiment, the point update unit 37 (point addition unit) adds many special points according to the total price of the products. Therefore, it is possible to encourage customers to purchase products other than the specific product.

[0061] In addition, in the POS terminal 10 (product sales data processing device) of the first embodiment, the point update unit 37 (point addition unit) adds special points to each specific product purchased by the customer. This can further encourage customers to purchase.

[0062] Although the present invention has been described above as being applied to a face-to-face POS terminal, the present invention can also be applied to self-service POS and semi-self-service POS in the same manner.

[0063] (Second embodiment) When the specific product described in the first embodiment is purchased, the fact that special points according to the purchase amount are added is announced by advertising media such as flyers and POP placed in stores, but it is desirable to make customers more aware of this. The second embodiment described below is an example of a shopping cart 100 equipped with a function of notifying customers that special points will be added when a specific product is registered. The shopping cart 100 has a cart terminal 102 described later. The cart terminal 102 is an example of a product sales data processing device in the present invention.

[0064] First, the operation state of a shopping cart 100 having a cart terminal 102 according to the second embodiment of the present invention will be described with reference to Fig. 7. Fig. 7 is a system block diagram showing an example of the operation state of a shopping cart according to the second embodiment.

[0065] 7, checkout system 95 includes a plurality of shopping carts 100 carried by customers, an attendant terminal 121, a POS terminal 122, a plurality of wireless communication units 123, a router 120, and a point management server 90. Attendant terminal 121, POS terminal 122, and wireless communication unit 123 are connected to each other via network 124.

[0066] The shopping cart 100 has a product registration function for registering products to be purchased by a customer, and stores the products to be purchased by the customer. The product registration function is realized by the cart terminal 102.

[0067] The attendant terminal 121 is an information processing device such as a personal computer operated by a store clerk called an attendant. The attendant terminal 121 wirelessly communicates with each shopping cart 100 to monitor the usage status of the shopping cart 100.

[0068] When a customer using the shopping cart 100 selects cash payment, the POS terminal 122 performs payment processing for the products that the customer has registered and placed in the shopping cart 100 .

[0069] A plurality of wireless communication units 123 are installed in the store, and wirelessly connect the cart terminal 102 provided in the shopping cart 100 to the attendant terminal 121 and the POS terminal 122 .

[0070] The router 120 connects the in-store network 124 and the point management server 90 via the Internet 84 .

[0071] The point management server 90 manages information such as points given to members.

[0072] (Explanation of shopping cart configuration) FIG. 8 is an external view showing an example of a shopping cart according to the second embodiment. The shopping cart 100 includes a basket-shaped storage section 250 with an open top, caster sections 252 for moving the shopping cart arranged below the storage section 250, and a handle section 254 that is connected to the storage section 250 and that a customer grasps when moving the shopping cart 100. A net is stretched over the sides and bottom of the storage section 250, and the products are stored in a manner that allows them to be seen from the outside. A customer takes a product to be purchased from a product shelf and stores it in the storage section 250. This allows the customer and the store clerk to easily know the details of the products stored in the storage section 250.

[0073] A cart terminal 102 is attached to the handle 254 of the shopping cart 100 via a holder (not shown). The cart terminal 102 has a housing 103, which is provided with a monitor 104, such as an LCD panel, a touch panel 105 attached to the display surface of the monitor 104, and a scanner 106 for reading a code symbol, such as a barcode or a two-dimensional code, that is attached to a product and associated with product information of the product. The scanner 106 incorporates an LED (Light Emitting Diode) that is an illumination for illuminating the product with light, a CCD (Charged Coupled Device) image sensor that receives light reflected from the product, and a decoder (all not shown) that decodes the light received by the image sensor and converts it into a digital signal. A reading window 107 is provided on one side of the scanner 106 for emitting light from the LED to read the code symbol.

[0074] The cart terminal 102 also includes a card reader 108. The card reader 108 reads information registered on a store membership card or credit card held by a customer.

[0075] When a customer places an item in the shopping cart 100, the customer holds the code symbol attached to the item over the reading window 107. The scanner 106 reads the code symbol. The scanner 106 also decodes the read code symbol. The cart terminal 102 analyzes the decoded digital signal to obtain a product code that identifies the item. The product whose code symbol has been read is then registered as a purchased item.

[0076] When the scanner 106 of the cart terminal 102 reads the code symbol of a specific product described in the first embodiment, the cart terminal 102 displays on the monitor 104 that special points will be awarded according to the total price of the products and the quantity of the specific products.

[0077] In addition, the cart terminal 102 performs payment processing for registered products.

[0078] Shopping cart 100 is equipped with an LED light 258 at the tip of an upright pole 256. LED light 258 changes its illumination state in accordance with the status of the customer's purchase (e.g. unpaid, paid, etc.). LED light 258 is installed at the tip of pole 256, i.e., at a high position, so that not only the customer but also store staff and others around shopping cart 100 can recognize that LED light 258 is emitting light.

[0079] (Explanation of the hardware configuration of the shopping cart) Next, the hardware configuration of the cart terminal 102 will be described with reference to Fig. 9. Fig. 9 is a hardware block diagram showing an example of the hardware configuration of the cart terminal. As shown in Fig. 9, the cart terminal 102 includes a control unit 130, a storage unit 134, a controller 135, and a communication control unit 136.

[0080] The control unit 130 has a typical computer configuration including a CPU 131, a ROM 132, and a RAM 133. The CPU 131 reads out various programs, data files, and the like stored in the ROM 132 and a storage unit 134 (described later), and loads them in the RAM 133. The CPU 131 operates in accordance with the various programs, data files, and the like loaded in the RAM 133, and is responsible for the overall control of the cart terminal 102.

[0081] The control unit 130 is connected to the storage unit 134 , the controller 135 , and the communication control unit 136 via an internal bus 137 .

[0082] The storage unit 134 retains stored information even when the power is turned off. The storage unit 134 is, for example, a HDD. Instead of the HDD, a non-volatile memory such as a flash memory may be provided. The storage unit 134 stores programs including the control program P2. The control program P2 is a program for implementing functions provided in the cart terminal 102.

[0083] The storage unit 134 further stores a product master file M1. The product master file M1 is a master file that stores product information such as product names and unit prices in association with product codes. The product master file M1 is updated successively as the cart terminal 102 communicates with a store server (not shown).

[0084] In addition, the memory unit 134 stores a sales file in which product information relating to products purchased by customers is registered, but since this is not a characteristic component of this embodiment, illustrations and detailed explanations are omitted.

[0085] The controller 135 connects the control unit 130 to the input / output devices, that is, the monitor 104, the touch panel 105, the scanner 106, the card reader 108, and the LED light 258. The functions of each of the input / output devices are as described above.

[0086] The communication control unit 136 controls communication with the wireless communication unit 123 to input and output various types of information between the cart terminal 102 and the attendant terminal 121 and POS terminal 122 .

[0087] (Explanation of the functional configuration of the cart terminal) Next, the functional configuration of the cart terminal 102 will be described with reference to Fig. 10. Fig. 10 is a functional block diagram showing an example of the functional configuration of the cart terminal.

[0088] The control unit 130 (see Figure 9) of the cart terminal 102 deploys the control program P2 in RAM 133 and operates it to realize, as functional units, the customer identification unit 30, the point acquisition unit 31, the code symbol reading unit 32, the product registration processing unit 33, the point calculation unit 34, the point update unit 37, the payment processing unit 38, and the information provision unit 39 shown in Figure 10.

[0089] 10 is the functional configuration of the first embodiment to which an information providing unit 39 is added. The functions of the functional parts other than the payment processing unit 38 and the information providing unit 39 are the same as those described in the first embodiment.

[0090] If the cart terminal 102 does not have a card reader, the customer identification unit 30 recognizes the membership number entered on the touch panel 105 to identify the customer's membership number (identification number).

[0091] When a customer selects cashless payment, the payment processor 38 performs payment processing with the details of the product registered by the product registration processor 33, based on the registration information of, for example, the customer's credit card, read by the card reader 108. When a customer selects cash payment, the cash payment is made at the POS terminal 122 (see FIG. 7).

[0092] The information providing unit 39 provides information that special points will be added to the specific product according to the total price of the purchased product, on condition that the code symbol reading unit 32 has read the code symbol attached to the specific product. Specifically, the information providing unit 39 displays information, which will be described later, on the monitor 104 of the cart terminal 102 (see FIG. 11).

[0093] (Example of information provided on the cart terminal) Next, an example of the structure of information provision displayed on the monitor 104 of the cart terminal 102 will be described with reference to Fig. 11. Fig. 11 is a diagram showing an example of a screen displayed on the cart terminal.

[0094] The information providing unit 39 displays, for example, screen information 115 on the monitor 104 of the cart terminal 102. The screen information 115 is information indicating that when product A (specific product) is purchased, special points according to the purchase amount will be added.

[0095] Additionally, a details button 110 and a display-off button 111 are displayed on the monitor 104. The details button 110 is a button for displaying detailed information about the special points. The display-off button 111 is a button for erasing the screen information 115 and returning to the original screen.

[0096] When the customer presses the details button 110, the information providing unit 39 displays screen information 116 shown in FIG. 11 on the monitor 104 of the cart terminal 102. The screen information 116 shows the contents of the above-mentioned table Ta (see FIG. 5). In addition, a back button 112 is displayed on the monitor 104. The back button 112 is a button for erasing the screen information 116 and returning to the screen information 115.

[0097] (Explanation of the processing flow performed by the cart terminal) Next, the flow of processing performed by the cart terminal 102 will be described with reference to Fig. 12. Fig. 12 is a flow chart showing an example of the flow of processing performed by the cart terminal.

[0098] The process flow (steps S30 to S42) shown in FIG. 12 is almost the same as the process flow (see FIG. 6) performed by the POS terminal 10 described in the first embodiment. The difference is in step S36, where information about special points related to a specific product is provided. That is, in step S36, the information providing unit 39 displays, for example, information shown in FIG. 11 on the monitor 104 of the cart terminal 102. Then, although not shown in FIG. 12, when the display erase button 111 (see FIG. 11) is pressed, the process proceeds to step S37.

[0099] 12 is executed only when the customer selects cashless payment. If the customer selects cash payment, the payment is processed by the POS terminal 122 as described above.

[0100] As described above, in the cart terminal 102 (product sales data processing device) of the second embodiment, on condition that the code symbol reading unit 32 (reading unit) reads the code symbol attached to the specific product, the information providing unit 39 provides the customer with information that special points will be added to the specific product according to the total price of the products to be purchased. Therefore, the customer can know that special points will be added to the specific product according to the total price of the products to be purchased. This can stimulate the customer's desire to purchase further.

[0101] Although the embodiments of the present invention have been described above, these embodiments are merely examples and are not intended to limit the scope of the invention. These novel embodiments can be implemented in various other forms, and various omissions, substitutions, and modifications can be made without departing from the spirit of the invention. These embodiments and their modifications are included in the scope and spirit of the invention, and are included in the scope of the invention and its equivalents described in the claims.
