As shown in FIG. 1, the eco bag 10 includes a main body 11, a handle 12, and a member tag 13. The eco bag 10 is an example of a container in the present disclosure. The member tag 13 is, for example, an RFID (Radio Frequency Identification) tag.

[0010] The main body 11 is a storage section into which products are put. The main body 11 has a large gusset (thickness) so that as many products as possible can be put in.

[0011] The handle 12 is a gripping portion that a customer holds when carrying the eco bag 10.

[0012] The member tag 13 outputs information to a communication device 30 (see FIG. 2) described below by wirelessly communicating with the communication device 30. A member code, for example, that uniquely identifies the customer is written on the member tag 13. The member tag 13 is, for example, an RFID tag. The member tag 13 is attached or sewn onto the eco bag 10. The member tag 13 may also be woven into the fabric of the eco bag 10.

[0013] The eco-bag 10 may be sold at the store for a fee. Alternatively, the eco-bag 10 may be rented at the store for a fee. In this case, a guest code that uniquely identifies the guest customer is written on the member tag 13.

[0014] (Shopping cart outline) The general structure of a shopping cart 20 used by a customer when shopping will be described with reference to Fig. 2. Fig. 2 is an external view showing an example of a shopping cart used in the product sales data processing system of the embodiment.

[0015] The shopping cart 20 is a plastic basket commonly used in stores. As shown in FIG. 2, the shopping cart 20 includes a main body 21, a handle 22, and a communication device 30.

[0016] The main body 21 is a storage section into which products are put. In this embodiment, the shopping basket 20 is used with the eco-bag 10 stored in the main body 21. This will be described in detail later (see FIG. 3).

[0017] The handle 22 is a gripping portion that a customer holds when carrying the shopping basket 20.

[0095] The payment completion information output unit 88 outputs payment completion information indicating that the payment has been completed to the communication device 30 and the mobile terminal 40. In addition, the payment completion information output unit 88 outputs payment information indicating the details of the payment to the mobile terminal 40.

[0096] The checkout processing unit 89 performs checkout processing to disconnect communication between the store server 50 and the communication device 30 installed in the shopping cart 20 that the customer was using while shopping.

[0097] (Processing flow performed by the product sales data processing system) The flow of processing performed by the merchandise sales data processing system 100 of the first embodiment will be described with reference to Fig. 11. Fig. 11 is a flowchart showing an example of the flow of processing performed by the merchandise sales data processing system of the first embodiment.

[0098] (Processing flow performed by communication device) First, the flow of processing performed by the communication device 30 will be described.

[0099] The wireless tag reader 61 reads the customer's membership code registered on the membership tag 13 attached to the eco-bag 10 contained in the shopping cart 20 (step S11). It is assumed that the shopping cart 20 contains the customer's eco-bag 10.

[0100] When the check-in completion information is received from the store server 50, the wireless tag reading unit 61 reads the product codes registered on the product tags 14 attached to the products 15 that the customer put into the eco bag 10 (step S12). The wireless tag reading unit 61 repeatedly reads the product tags 14. If the products 15 that were put into the eco bag 10 are removed from the eco bag 10, the wireless tag reading unit 61 no longer reads the information registered on the product tags 14 attached to the removed products 15. Therefore, the latest reading result of the wireless tag reading unit 61 indicates the product codes of all the products 15 that are currently in the eco bag 10. If the wireless tag reading unit 61 detects that products 15 have been put into the eco bag 10 before receiving the check-in completion information, the notification unit 65 may activate the speaker 34 to notify the customer that shopping is not permitted. Furthermore, the notification unit 65 may issue a notification by sounding the speaker 34 when a product 15 is placed in the shopping cart 20 without containing an eco-bag 10. This can prevent fraudulent behavior by customers.

[0101] The notification unit 65 determines whether the eco bag 10 has been removed from the shopping cart 20 (step S13). If it is determined that the eco bag 10 has been removed from the shopping cart 20 (step S13: Yes), the process proceeds to step S14. On the other hand, if it is not determined that the eco bag 10 has been removed from the shopping cart 20 (step S13: No), the process proceeds to step S15. The notification unit 65 determines whether the eco bag 10 has been removed when the wireless tag reading unit 61 no longer reads the membership code of the membership tag 13 attached to the eco bag 10.

[0102] In step S13, if it is determined that the eco-bag 10 has been removed from the shopping cart 20 without the payment completion information acquisition unit 64 having acquired payment completion information from the store server 50, the notification unit 65 sounds an alarm through the speaker 34 to notify the customer that payment for the items placed in the eco-bag 10 has not been completed (step S14). This prevents fraudulent activity such as the customer leaving unpaid items in the eco-bag 10. After that, when the customer places the eco-bag 10 in the shopping cart 20, the process returns to step S12.

[0103] On the other hand, if it is not determined in step S13 that the eco bag 10 has been removed from the shopping cart 20, when the payment process for the product 15 placed in the eco bag 10 is completed by a payment instruction issued by the mobile terminal 40 to the store server 50, the payment completion information acquisition unit 64 acquires payment completion information from the store server 50 (step S15).

[0104] The notification unit 65 determines whether the eco bag 10 has been removed from the shopping cart 20 (step S16). If it is determined that the eco bag 10 has been removed from the shopping cart 20 (step S16: Yes), the communication device 30 ends the process. On the other hand, if it is not determined that the eco bag 10 has been removed from the shopping cart 20 (step S16: No), step S16 is repeated.

[0105] (Processing flow performed by mobile devices) Next, the flow of processing performed by the mobile terminal 40 will be described.

[0106] When the check-in completion information acquisition unit 71 of the mobile terminal 40 acquires the check-in completion information from the store server 50, it transitions the mobile terminal 40 to an in-store mode in which the customer can shop (step S21).

[0107] The product registration information acquisition unit 72 acquires product information of the product that the customer puts into the eco-bag 10 from the store server 50, and displays the acquired product information on the display device 45 (step S22).

[0108] When it is detected that the customer has performed an operation to instruct payment on the mobile terminal 40, the payment instruction unit 73 issues a payment instruction to the store server 50 (step S23). Following the payment instruction, the payment instruction unit 73 outputs the payment method selected by the customer to the store server 50.

[0109] The payment completion information acquisition unit 74 acquires payment completion information and payment information indicating the payment details from the store server 50 (step S24). After that, the mobile terminal 40 ends the process.

[0110] (Processing flow performed by the store server) Next, the flow of processing performed by the store server 50 will be described.

[0111] The check-in processing unit 82 performs check-in processing based on the customer's membership code acquired by the wireless tag information acquisition unit 81 from the communication device 30 (step S31).

[0112] The check-in completion information output unit 83 outputs the check-in completion information to the mobile terminal 40 and the communication device 30 (step S32).

[0113] The product registration processing unit 84 acquires the product code output from the communication device 30 and compares it with the product master 523. Then, the product registration processing unit 84 registers the product information of the product corresponding to the product code (step S33).

[0114] The product registration information output unit 85 outputs the product registration information registered in step S33 to the mobile terminal 40 (step S34).

[0115] The payment instruction acquisition unit 86 acquires the payment instruction and the payment method from the mobile terminal 40. Then, the payment processing unit 87 requests an external payment server (not shown) to perform payment processing using the instructed payment method (step S35).

[0116] The payment completion information output unit 88 outputs payment completion information to the communication device 30 and the mobile terminal 40. The payment completion information output unit 88 also outputs payment information indicating the details of the payment to the mobile terminal 40 (step S36).

[0117] The checkout processing unit 89 performs checkout processing to disconnect communication between the communication device 30 installed in the shopping cart 20 that the customer was using while shopping and the store server 50. After that, the store server 50 ends the processing.

[0118] (Operation and effect of the first embodiment) As described above, in the product sales data processing system 100 of the first embodiment, the communication device 30 is provided with: a wireless tag reader 61 (an example of a reader) that is installed in the shopping cart 20 and reads a membership code attached to an eco-bag 10 (an example of a container) that is contained in the shopping cart 20 and into which a product 15 can be placed; a read information output unit 62 (an example of an output unit) that outputs the membership code read by the wireless tag reader 61 to the store server 50 (an example of a server device); and a check-in completion information acquisition unit 63 (an example of an acquisition unit) that acquires check-in completion information that permits shopping at the store from the store server 50 when the membership code is output to the store server 50. Therefore, since the use of the eco-bag 10 is essential when shopping, it is possible to prevent forgetting to bring the eco-bag 10 when shopping, thereby promoting the use of the eco-bag 10.

[0119] Furthermore, in the communication device 30 of the first embodiment, the wireless tag reading unit 61 (an example of a reading unit) further reads the product code of the product 15 placed in the eco bag 10 (an example of a container), and when the wireless tag reading unit 61 reads the product code of the product 15 placed in the eco bag 10, the read information output unit 62 (an example of an output unit) outputs the product code to the store server 50 (an example of a server device), thereby causing the store server 50 to generate product registration information corresponding to the product code. Therefore, a customer can register the product by simply placing the product to be purchased in the eco bag 10 without performing any special operation.

[0120] Furthermore, in the communication device 30 of the first embodiment, the wireless tag reading unit 61 (an example of a reading unit) further reads the product code of the product 15 placed in the eco bag 10 (an example of a container), and when the wireless tag reading unit 61 is unable to read the product code of the product 15 after the product 15 is removed from the eco bag 10, the read information output unit 62 (an example of an output unit) outputs the product code to the store server 50 (an example of a server device), thereby causing the store server 50 to cancel the product registration information corresponding to the product code. Therefore, if a customer decides not to purchase a product that they have placed in the eco bag 10, they can simply remove the product from the eco bag 10 to cancel the product registration without performing any special operations.

[0121] The communication device 30 of the first embodiment further includes a payment completion information acquisition unit 64 that acquires payment completion information indicating that payment for the product 15 has been completed from the store server 50, and an alarm unit 65 that notifies the customer that payment for the product 15 placed in the eco bag 10 has not been completed if the wireless tag reading unit 61 (an example of a reading unit) is unable to read the membership code attached to the eco bag 10 while the payment completion information acquisition unit 64 has not acquired the payment completion information. This prevents customers from committing fraudulent acts such as removing the eco bag 10 containing the unpaid product 15 from the shopping cart 20 and taking it home when shopping.

[0122] Furthermore, in the communication device 30 of the first embodiment, if the wireless tag reading unit 61 (an example of a reading unit) reads the product code attached to the product 15 placed in the eco bag 10 while the check-in completion information acquiring unit 63 (an example of an acquiring unit) has not acquired check-in completion information permitting shopping from the store server 50 (an example of a server device), the notification unit 65 further notifies that shopping at the store is not permitted. Therefore, it is possible to prevent fraudulent acts such as placing products in an eco bag 10 that does not have a membership tag 13 attached.

[0123] (Second embodiment) The general configuration of a merchandise sales data processing system 110 according to the second embodiment will be described with reference to Fig. 12. Fig. 12 is a diagram showing the general configuration of the merchandise sales data processing system according to the second embodiment.

[0124] The product sales data processing system 110 includes a communication device 30 installed in a shopping cart 20 containing an eco-bag 10, a mobile terminal 40, a store server 50, and a checkout device 160.

[0125] The eco bag 10, the shopping basket 20, the communication device 30, and the mobile terminal 40 are all as described in the first embodiment.

[0126] The store server 150 performs a check-in process to allow a customer who has placed an eco-bag 10 in the shopping cart 20 to shop at the store. The store server 150 also performs a product registration process to register a product corresponding to a product code acquired from the communication device 30. The store server 150 is an example of a server device in the present disclosure.

[0127] The checkout device 160 accepts payment instructions from the mobile terminal 40. The checkout device 160 also performs payment processing related to the product registration information obtained from the store server 150 in accordance with the accepted payment instructions.

[0128] The communication device 30 is communicably connected to the store server 150. The mobile terminal 40 is communicably connected to the store server 150.

[0129] The communication device 30 transmits to the store server 150 the membership code read from the membership tag 13 of the eco bag 10. The communication device 30 also transmits to the store server 150 the product code read from the product tag 14 attached to the product 15 that the customer puts into the eco bag 10.

[0130] The store server 150 transmits check-in completion information indicating that check-in to the store has been completed to the communication device 30. The store server 150 also transmits payment completion information indicating that payment processing for the product 15 placed in the eco bag 10 has been completed to the communication device 30.

[0131] The store server 150 transmits check-in completion information to the mobile terminal 40, indicating that check-in to the store has been completed. The store server 150 also transmits product registration information to the mobile terminal 40, indicating that registration of the product placed in the eco bag 10 has been completed. Furthermore, the store server 150 transmits payment completion information to the mobile terminal 40, indicating that payment processing for the product 15 placed in the eco bag 10 has been completed.

[0132] The checkout device 160 is connected to the store server 150 via a wired connection, for example, via an in-store LAN. Note that the checkout device 160 and the store server 150 may also be connected wirelessly.

[0133] The store server 150 transmits the member information and product registration information to the checkout device 160.

[0134] The checkout device 160 sends the member information and payment completion information to the store server 150.

[0135] Furthermore, the accounting device 160 reads a code symbol containing member information that the customer has displayed on the mobile terminal 40, allowing the customer to make a payment at the accounting device 160.

[0136] (Hardware configuration of accounting device) The hardware configuration of the transaction device 160 will be described using Figure 13. Figure 13 is a hardware block diagram showing an example of the hardware configuration of a transaction device.

[0137] The accounting device 160 includes a control unit 95 , a memory unit 96 , a peripheral device controller 97 , and a communication interface 98 .

[0138] The control unit 95 controls the overall operation of the checkout device 160. The control unit 95 includes a CPU 951, a ROM 952, and a RAM 953. The CPU 951 is connected to the ROM 952 and RAM 953 via internal buses such as an address bus and a data bus. The CPU 951 loads various programs stored in the ROM 952 and the storage unit 96 into the RAM 953. The CPU 951 controls the operation of the checkout device 160 by operating in accordance with the various programs loaded into the RAM 953. In other words, the control unit 95 has the configuration of a typical computer.

[0139] The storage unit 96 is a storage device such as an HDD or SSD. Alternatively, the storage unit 96 may be a non-volatile memory such as a flash memory that retains stored information even when the power is turned off. The storage unit 96 stores a control program 961 and product registration information 962.

[0140] The control program 961 is a program that controls the overall operation of the accounting device 160. The control program 961 may be provided stored in the storage unit 96, or may be provided by being recorded in an installable or executable file on a computer-readable non-transitory recording medium such as a CD-ROM, flexible disk (FD), CD-R, or DVD. The control program 961 may also be stored on a computer connected to a network and provided by being downloaded via the network. Furthermore, the control program 961 may be provided or distributed via a network such as the Internet.

[0141] The product registration information 962 is information that stores product information about the product 15 purchased by a customer. The product registration information 962 includes the product code, product name, quantity, unit price, total price, etc. The product registration information 962 is stored in association with the membership code of the customer who purchases the product 15.

[0142] The control unit 95 is connected to a display device 111 , an operation device 112 , a scanner 113 , a change dispenser 114 , and a receipt printer 115 via a peripheral device controller 97 .

[0143] The display device 111 is, for example, a liquid crystal monitor, an organic EL monitor, etc. The display device 111 displays various screens to the customer, such as a registration details screen displaying registered product information, a payment screen showing payment details, etc.

[0144] The operation device 112 is, for example, a touch panel superimposed on the display screen of the display device 111. The operation device 112 acquires various operation information from customers and outputs it to the control unit 95. The operation device 112 may also be a keyboard or a physical switch.

[0145] The scanner 113 is a reading device that reads a code symbol containing member information that the customer has displayed on the display device 45 of the mobile terminal 40. The scanner 113 may be a handheld reading device that the customer holds to read the code information, or may be a stationary reading device.

[0146] When a customer makes a cash payment, the change dispenser 114 accepts inserted coins or bills and dispenses coins or bills as change.

[0147] The receipt printer 115 prints and issues a receipt indicating the result of the payment.

[0148] The communication interface 98 controls wireless communication between the control unit 95 and the store server 150 .

[0149] The hardware configurations of the communication device 30 and the mobile terminal 40 are the same as those described in the first embodiment, and therefore will not be described again. The hardware configuration of the store server 150 is the same as that of the store server 50 described in the first embodiment, and therefore will not be described again.

[0150] (Store server functional configuration) The functional configuration of the store server 150 will be described using Fig. 14. Fig. 14 is a functional block diagram showing an example of the functional configuration of the store server of the second embodiment. Note that the hardware configuration of the store server 150 is the same as the hardware configuration of the store server 50 described above, and therefore the hardware components of the store server 150 will be described using the same reference numerals as those shown in Fig. 7.

[0151] The control unit 51 of the store server 150 reads out the control program 521, expands it into the RAM 513 provided in the control unit 51, and executes it, thereby realizing the wireless tag information acquisition unit 81, check-in processing unit 82, check-in completion information output unit 83, product registration processing unit 84, product registration information output unit 90, member information acquisition unit 91, payment completion information acquisition unit 92, payment completion information output unit 88, and checkout processing unit 89 shown in Figure 14 as functional units.

[0152] Of these, the functions of the wireless tag information acquisition unit 81, check-in processing unit 82, check-in completion information output unit 83, product registration processing unit 84, payment completion information output unit 88, and check-out processing unit 89 are the same as those described in the first embodiment, so repeated explanation will be omitted.

[0153] The product registration information output unit 90 outputs the product registration information 524 to the mobile terminal 40. In addition, the product registration information output unit 90 outputs the product registration information 524 of the customer corresponding to the membership information acquired from the checkout device 160 to the checkout device 160, associating it with the customer's membership information.

[0154] The member information acquisition unit 91 acquires, from the accounting device 160, the member information of the customer who has issued the accounting instruction.

[0155] The payment completion information acquisition unit 92 acquires from the checkout device 160 payment completion information indicating that the payment has been completed, and payment information indicating the details of the payment.

[0156] (Functional configuration of accounting device) The functional configuration of the transaction device 160 will be described using Figure 15. Figure 15 is a functional block diagram showing an example of the functional configuration of the transaction device.

[0157] The control unit 95 of the accounting device 160 reads the control program 961, expands it into RAM 963 provided in the control unit 95, and executes it, thereby realizing the functional units of the member information acquisition unit 101, member information output unit 102, payment instruction acquisition unit 103, product registration information acquisition unit 104, payment processing unit 105, payment completion information output unit 106, and receipt issuing unit 107 shown in Figure 15.

[0158] The member information acquisition unit 101 acquires the customer's membership code by using the scanner 113 to read a code symbol containing the membership code that the customer has displayed on the display device 45 of the mobile terminal 40.

[0159] The member information output unit 102 outputs the member code acquired by the member information acquisition unit 101 to the store server 150.

[0160] The payment instruction acquisition unit 103 acquires payment instruction information indicating the payment method based on operation information of the customer on the checkout device 160. The payment instruction acquisition unit 103 acquires the payment instruction by, for example, detecting that the customer has pressed the checkout button. The payment instruction acquisition unit 103 also acquires the payment method selected by the customer.

[0161] The product registration information acquisition unit 104 acquires the product registration information 524 associated with the customer's membership code from the store server 150.

[0162] The payment processing unit 105 performs payment processing for the product related to the product registration information 524 using the payment method acquired from the customer by the payment instruction acquisition unit 103.

[0163] The payment completion information output unit 106 outputs payment completion information indicating that the payment has been completed to the store server 150. The payment completion information output unit 106 also outputs payment information indicating the details of the payment to the store server 150.

[0164] The receipt issuing unit 107 prints the results of the payment processing performed by the payment processing unit 105 on a receipt using a receipt printer 115 and issues it.

[0165] (Functional configuration of communication device) The functional configuration of the communication device 30 included in the product sales data processing system 110 of the second embodiment is the same as the functional configuration of the communication device 30 included in the product sales data processing system 100 of the first embodiment (see FIG. 8), so a repeated description will be omitted. In the following description, the functional components of the communication device 30 will be described using the same reference numerals as those shown in FIG. 8.

[0166] (Functional configuration of mobile device) The functional configuration of the mobile terminal 40 included in the merchandise sales data processing system 110 of the second embodiment is the same as the functional configuration of the mobile terminal 40 included in the merchandise sales data processing system 100 of the first embodiment (see FIG. 9), so a repeated description will be omitted. In the following description, the functional components of the mobile terminal 40 will be described using the same reference numerals as those shown in FIG.

[0167] (Processing flow performed by communication device) The flow of processing performed by the communication device 30 included in the product sales data processing system 110 of the second embodiment will be described with reference to Fig. 16. Fig. 16 is a flowchart showing an example of the flow of processing performed by the communication device.

[0168] The wireless tag reading unit 61 determines whether the membership code has been read (step S41). If it is determined that the membership code has been read (step S41: Yes), the process proceeds to step S42. On the other hand, if it is not determined that the membership code has been read (step S41: No), step S41 is repeated. In this step, it is determined whether the customer has placed the eco bag 10 in the shopping cart 20. That is, when the customer places the eco bag 10 in the shopping cart 20, the wireless tag reading unit 61 can read the membership code registered on the membership tag 13 attached to the eco bag 10, and therefore the wireless tag reading unit 61 determines that the membership code has been read.

[0169] If it is determined in step S41 that the membership code has been read, the read information output unit 62 outputs the membership code to the store server 150 (step S42).

[0170] Next, the wireless tag reader 61 determines whether the product code has been read (step S43). If it is determined that the product code has been read (step S43: Yes), the process proceeds to step S44. On the other hand, if it is not determined that the product code has been read (step S43: No), step S43 is repeated.

[0171] If it is determined in step S43 that the product code has been read, the read information output unit 62 outputs the product code to the store server 150 (step S44). At this time, the read information output unit 62 associates the product code registered in the product tag 14 attached to the product with the membership code registered in the membership tag 13 attached to the eco bag 10, and outputs the associated information to the store server 150. This is to enable the store server 150 to recognize which eco bag 10 the product code belongs to.

[0172] Next, the wireless tag reader 61 determines whether the membership code registered in the membership tag 13 attached to the eco bag 10 can be read (step S45). If it is determined that the membership code cannot be read (step S45: Yes), the process proceeds to step S46. On the other hand, if it is not determined that the membership code cannot be read (step S45: No), the process proceeds to step S47. Note that the case where the membership code registered in the membership tag 13 attached to the eco bag 10 cannot be read assumes that the eco bag 10 is removed from the shopping cart 20 before the payment for the items 15 placed in the eco bag 10 is completed. In such a case, the wireless tag reader 61 is unable to read the membership code registered in the membership tag 13 attached to the eco bag 10, and therefore determines in step S45 that the membership code cannot be read.

[0173] If it is determined in step S45 that the membership code cannot be read, the notification unit 65 sounds an alarm through the speaker 34 (step S46). Then, the process returns to step S45. At this time, the customer who notices the alarm attaches the eco bag 10 to the shopping cart 20.

[0174] If it is not determined in step S45 that the membership code cannot be read, that is, if it is determined that the membership code has been read, the notification unit 65 determines whether an alarm is sounding (step S47). If it is determined that the alarm is sounding (step S47: Yes), the process proceeds to step S48. On the other hand, if it is not determined that the alarm is sounding (step S47: No), the process proceeds to step S49.

[0175] If it is determined in step S47 that the alarm is sounding, the notification unit 65 causes the speaker 34 to stop sounding the alarm (step S48). This allows a customer who has removed the eco-bag 10 from the shopping cart 20 to notice the alarm sounding and place the eco-bag 10 back into the shopping cart 20, thereby stopping the sounding of the alarm.

[0176] Following step S48, or if it is determined in step S47 that the alarm is not sounding, the payment completion information acquisition unit 64 determines whether payment completion information has been acquired from the store server 150 (step S49). If it is determined that payment completion information has been acquired from the store server 150 (step S49: Yes), the communication device 30 ends the processing. On the other hand, if it is not determined that payment completion information has been acquired from the store server 150 (step S49: No), the processing returns to step S43.

[0177] (Processing flow performed by the store server device) The flow of processing performed by the store server 150 included in the merchandise sales data processing system 110 of the second embodiment will be described with reference to Fig. 17. Fig. 17 is a flowchart showing an example of the flow of processing performed by the store server.

[0178] The wireless tag information acquisition unit 81 determines whether a membership code has been acquired from the communication device 30 (step S51). If it is determined that a membership code has been acquired (step S51: Yes), the process proceeds to step S52. On the other hand, if it is not determined that a membership code has been acquired (step S51: No), step S51 is repeated. Whether a membership code has been acquired from the communication device 30 is determined by the store server 150 acquiring the membership code registered in the membership tag 13 attached to the eco bag 10, which is output by the communication device 30.

[0179] If it is determined in step S51 that a membership code has been acquired, the check-in processing unit 82 performs check-in processing to permit the customer who has the acquired membership code to shop at the store (step S52).

[0180] The check-in completion information output unit 83 outputs check-in completion information indicating that check-in has been completed to the communication device 30 and the mobile terminal 40 (step S53).

[0181] Next, the wireless tag information acquisition unit 81 determines whether the product code has been acquired from the communication device 30 (step S54). If it is determined that the product code has been acquired (step S54: Yes), the process proceeds to step S55. On the other hand, if it is not determined that the product code has been acquired (step S54: No), the process proceeds to step S57. Whether the product code has been acquired from the communication device 30 is determined by the store server 150 acquiring the product code registered in the product tag 14 attached to the product 15 placed in the eco bag 10, which is output by the communication device 30.

[0182] If it is determined in step S54 that the product code has been acquired, the product registration processing unit 84 acquires product information for the product corresponding to the acquired product code from the product master 523. Then, the product registration processing unit 84 performs product registration processing to generate product registration information 524 for purchase by the customer who has the membership code acquired in step S51 (step S55).

[0183] The product registration information output unit 90 outputs the product registration information 524 to the mobile terminal 40 (step S56). This allows the customer to confirm that the product he or she wants to purchase has been registered by checking the product registration information acquired by the mobile terminal 40.

[0184] The member information acquisition unit 91 determines whether the member code of the customer who issued the transaction instruction has been acquired from the transaction device 160 (step S57). If it is determined that the customer's member code has been acquired (step S57: Yes), the process proceeds to step S58. On the other hand, if it is not determined that the customer's member code has been acquired (step S57: No), the process proceeds to step S54.

[0185] In step S57, if it is determined that the customer's membership code has been acquired, the product registration information output unit 90 associates the customer's product registration information 524 corresponding to the membership code acquired from the accounting device 160 with the customer's membership code and outputs it to the accounting device 160 (step S58).

[0186] The payment completion information acquisition unit 92 determines whether payment completion information has been acquired from the checkout device 160 (step S59). If it is determined that payment completion information has been acquired (step S59: Yes), the process proceeds to step S60. On the other hand, if it is determined that payment completion information has not been acquired (step S59: No), step S59 is repeated.

[0187] If it is determined in step S58 that the payment completion information has been acquired, the payment completion information output unit 88 outputs the payment completion information to the communication device 30 and the mobile terminal 40 (step S60).

[0188] The checkout processing unit 89 performs a checkout process to disconnect communication between the communication device 30 installed in the shopping cart 20 that the customer was using while shopping and the store server 150 (step S61). After that, the store server 150 ends the process.

[0189] (Processing flow performed by mobile devices) The flow of processing performed by the mobile terminal 40 included in the product sales data processing system 110 of the second embodiment will be described with reference to Fig. 18. Fig. 18 is a flowchart showing an example of the flow of processing performed by the mobile terminal.

[0190] The check-in completion information acquisition unit 71 determines whether check-in completion information has been acquired from the store server 150 (step S71). If it is determined that check-in completion information has been acquired (step S71: Yes), the process proceeds to step S72. On the other hand, if it is not determined that check-in completion information has been acquired (step S71: No), step S71 is repeated.

[0191] If it is determined in step S71 that check-in completion information has been acquired, the product registration information acquisition unit 72 determines whether product registration information 524 has been acquired from the store server 150 (step S72). If it is determined that product registration information 524 has been acquired (step S72: Yes), the process proceeds to step S73. On the other hand, if it is not determined that product registration information has been acquired (step S72: No), step S72 is repeated. Note that what the mobile terminal 40 acquires here is the product registration information of the product to be purchased by the member, from the product registration information 524 stored in the store server 150.

[0192] The display control unit 75 displays the product registration information 524 acquired in step S72, for example, as a registration details screen on the display device 45 of the mobile terminal 40 (step S73). This allows the customer to confirm that the product they wish to purchase has been registered.

[0193] The operation control unit 76 determines whether a checkout button (not shown) displayed on the display device 45 of the mobile terminal 40 has been pressed (step S74). If it is determined that the checkout button has been pressed (step S74: Yes), the process proceeds to step S75. On the other hand, if it is not determined that the checkout button has been pressed (step S74: No), the process returns to step S72.

[0194] If it is determined in step S74 that the checkout button has been pressed, the display control unit 75 causes the display device 45 of the mobile terminal 40 to display a code symbol including the membership code of the customer, i.e., the member. At this time, the display control unit 75 may also cause the display device 45 of the mobile terminal 40 to display information (such as a product registration number) that can uniquely identify the product registration information 524 obtained from the store server 150.

[0195] The information displayed on the display device 45 in step S75 is read by the scanner 113 of the checkout device 160. The checkout device 160 then performs payment processing based on the membership code and product registration number read from the mobile terminal 40. The flow of processing performed by the checkout device 160 will be described later (see FIG. 19).

[0196] Following step S75, the payment completion information acquisition unit 74 determines whether payment completion information has been acquired from the store server 150 (step S76). If it is determined that payment completion information has been acquired (step S76: Yes), the mobile terminal 40 ends the process. On the other hand, if it is not determined that payment completion information has been acquired (step S76: No), step S76 is repeated. Although not shown in the flowchart of FIG. 18, after it is determined that payment completion information has been acquired, the display control unit 75 of the mobile terminal 40 may display the acquired payment details together with the payment completion information on the display device 45.

[0197] (Processing flow performed by accounting device) The flow of processing performed by the checkout device 160 included in the product sales data processing system 110 of the second embodiment will be described using Figure 19. Figure 19 is a flowchart showing an example of the flow of processing performed by the checkout device.

[0198] The member information acquisition unit 101 determines whether it has acquired the member code displayed on the mobile terminal 40 (step S81). If it is determined that it has acquired the member code (step S81: Yes), it proceeds to step S82. On the other hand, if it is determined that it has not acquired the member code (step S81: No), it repeats step S81. The member information acquisition unit 101 may also cause the mobile terminal 40 to display information that can uniquely identify the product registration information 524 that the mobile terminal 40 acquired from the store server 150, and have the checkout device 160 read it.

[0199] If it is determined in step S81 that a membership code has been acquired, the membership information output unit 102 outputs the membership code to the store server 150 (step S82). Note that if the checkout device 160 reads information that can uniquely identify the product registration information 524 from the mobile terminal 40 in step S81, the member information output unit 102 outputs to the store server 150 information that can uniquely identify the read product information.

[0200] The product registration information acquisition unit 104 acquires product registration information 524 associated with the customer's membership code output in step S82 from the store server 150 (step S83). Note that, if the membership information output unit 102 outputs information that can uniquely identify product information to the store server 150 in step S82, the product registration information acquisition unit 104 acquires, from the store server 150, product registration information 524 that corresponds to the information that can uniquely identify the product information output in step S82.

[0201] The payment processing unit 105 performs payment processing related to the product registration information 524 acquired in step S83, based on the payment instructions and payment method acquired by the payment instruction acquisition unit 103 (step S84).

[0202] When the payment process is completed, the payment completion information output unit 106 outputs payment completion information and payment details to the store server 150 (step S85).

[0203] The receipt issuing unit 107 prints and issues the payment details on the receipt printer 115 (step S86). The checkout device 160 then ends the process.

[0204] (Effects of the second embodiment) As described above, the product sales data processing system 110 of the second embodiment includes a communication device 30 installed in the shopping cart 20, a store server 150 (an example of a server device), a mobile terminal 40 operated by a customer, and a checkout device 160. The communication device 30 includes a wireless tag reader 61 (an example of a reader) that reads a membership code attached to an eco-bag 10 that is placed in the shopping cart 20 and into which a product 15 can be placed, a read information output unit 62 (an example of an output unit) that outputs the membership code read by the wireless tag reader 61 to the store server 150, and a check-in completion information acquisition unit 63 (an example of an acquisition unit) that acquires check-in completion information from the store server 150 that permits shopping at the store when the membership code is output to the store server 150.

[0205] The store server 150 includes a wireless tag information acquisition unit 81 that acquires the membership code attached to the eco bag 10 from the communication device 30, a check-in completion information output unit 83 that outputs information authorizing shopping at the store to the communication device 30 and the mobile terminal 40 to which the membership code acquired by the wireless tag information acquisition unit 81 has been output, a product registration processing unit 84 that generates product registration information corresponding to the product code acquired from the communication device 30, a product registration information output unit 90 that outputs the product registration information registered by the product registration processing unit 84 to the mobile terminal 40 and the checkout device 160, and a payment completion information output unit 88 that outputs payment completion information indicating that payment related to the product registration information registered by the product registration processing unit 84 has been completed to the communication device 30 and the mobile terminal 40.

[0206] The mobile terminal 40 includes a payment completion information acquisition unit 74 that acquires payment completion information from the store server 150, and a product registration information acquisition unit 72 that acquires product registration information registered or canceled by the product registration processing unit 84 from the store server 150.

[0207] The accounting device 160 comprises a member information acquisition unit 101 that acquires a member code from the mobile terminal 40, a payment instruction acquisition unit 103 that acquires payment instruction information indicating the payment method based on operation information of the customer on the accounting device 160, a product registration information acquisition unit 104 that acquires product registration information associated with the member code from the store server 150, a payment processing unit 105 that performs payment for products related to the product registration information, and a payment completion information output unit 106 that outputs payment completion information to the store server 150 indicating that payment has been completed.

[0208] Therefore, since it is necessary to use the eco-bag 10 when shopping, it is possible to prevent forgetting to bring the eco-bag 10 when shopping, thereby promoting the use of the eco-bag 10.

[0209] 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. This novel embodiment can be embodied in various other forms, and various omissions, substitutions, and modifications can be made without departing from the spirit of the invention.
