Description

Technical Field

[0001] The present invention relates to a sales method, and more particularly to a technique for improving the efficiency of product sales at event venues and the like.

Background Art

[0002] As a sales form using an IC card for product sales, for example, in a sales form where only product samples are displayed at the sales floor and the purchased products are stored in a backyard or the like, a membership card (contactless IC card) storing a member ID is read by an electronic shelf label (ID reader), and a product sales system for making a purchase reservation for the product has been proposed (Patent Document 1). In this product sales system, not only is the operation of making a product reservation by a customer simple, but also when the number of purchase reservations is updated, the inventory quantity can be automatically updated, so that inventory management becomes easy and the efficiency of sales is improved.

[0003] By the way, at event venues such as sports games and concerts, services for selling products such as goods and photos on the day of the game or event are provided. This sales form called venue sales sometimes causes queues or the situation where products cannot be purchased due to being sold out, but since the purchasing awareness of purchasers is strong and it also serves as a place for communication among fans gathering at the venue, venue sales itself tends to be popular as an event. In addition, there is also the merit that goods can be purchased after checking the actual item.

[0015] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.

[0016] [First Embodiment] FIG. 1 is a diagram showing a sales system 1 according to the first embodiment of the present invention. In the following description, the sale of goods held at an event venue or the like will be described as an example. As shown in FIG. 1, the sales system 1 of the first embodiment includes an IC card 2 in which a user ID 251 is stored, a product panel 3 provided with user ID reading units 32a, 32b, 32c,... that read the user ID 251 stored in the IC card 2, a correction terminal 4, a cash register terminal 5, and a server 6. The product panel 3, the correction terminal 4, and the cash register terminal 5 are communicatively connected to the server 6 via a network 7.

[0017] The IC card 2 is a non-contact IC card that a purchaser holds when using the sales system 1. For example, it is an IC card used as a membership card, an admission ticket, etc., or an IC card distributed at an event venue. The configuration of the IC card 2 will be described with reference to FIGS. 2 to 4.

[0018] As shown in FIG. 2, the IC card 2 has a non-contact IC chip 21 and an antenna 27 inside. As shown in FIG. 3, the non-contact IC chip 21 includes a CPU (Central Processing Unit) 22, a ROM (Read Only Memory) 23, a RAM (Random Access Memory) 24, an EEPROM (Electrically Erasable Programmable Read Only Memory) 25, and an I / F (Interface) 26, etc., and is configured.

[0019] The CPU 22 calls and executes a program stored in the ROM 23 or EEPROM 25 in the work memory area on the RAM 24. The ROM 23 is a read-only memory that permanently holds programs, data, etc. The RAM 24 temporarily holds the loaded programs and data and provides a work area for the CPU 22 to perform various processes.

[0020] The EEPROM 25 is a non-volatile memory capable of rewriting data and has a storage area for storing the user ID 251 as shown in FIG. 4. The user ID 251 is information for identifying a user, such as a registration number registered when using the sales system 1, a membership number of a fan club, or other identification information.

[0021] The I / F 26 of the IC card 2 is an interface for a contactless IC card, for example, based on the ISO18092 standard. The CPU 22 of the contactless IC chip 21 transmits and receives information to and from the user ID readers 32a to 32f of the product panel 3, the user ID reader 51 of the cash register terminal 5, or the user ID reader 41 of the correction terminal 4 via the I / F 26 and the antenna 27 of FIG. 2. The antenna 27 circulates inside the substrate and both ends thereof are connected to the contactless IC chip 21.

[0022] Next, the configuration of the product panel 3 will be described. The product panel 3 is a product posting device installed in the event venue and has a product posting unit 30 for posting products or product images, a panel control device 31, and one or more user ID readers 32a, 32b, 32c,....

[0023] The panel control device 31 has a storage unit 312 that stores information (product ID) for identifying each product posted on the product display unit 30, and includes a control unit 311 that controls the operations of a plurality of user ID readers 32a, 32b, 32c,.... FIG. 5 is a diagram showing the configuration of a computer used as the panel control device 31. As shown in FIG. 5, the panel control device 31 is configured such that a control unit 311, a storage unit 312, a communication unit 313, an input unit 314, a display unit 315, and a peripheral device I / F unit 316 are connected via a bus 317. An IC card R / W (Reader / Writer), which is the user ID reader 32a, 32b, 32c,... shown in FIG. 1, is connected to the peripheral device I / F unit 316. However, the configuration of the panel control device 31 can be appropriately changed according to the application.

[0024] The control unit 311 is composed of a CPU, a ROM, a RAM, etc. The CPU calls a program stored in a storage medium such as the storage unit 312 and the ROM to the work area on the RAM and executes it. The ROM is a non-volatile memory that permanently stores programs and data such as a boot program and BIOS. The RAM is a volatile memory that temporarily stores programs and data loaded from the storage unit 312, the ROM, etc., and provides a work area used for the control unit 311 to perform various processes.

[0025] The storage unit 312 is a hard disk drive, a solid state drive, a flash memory, etc., and stores programs, data necessary for program execution, an OS, etc. that the panel control device 31 executes during the processes described later. These programs and data are read and executed by the control unit 311 as needed. A product ID list 34 (or RW ID list) is stored in the storage unit 312 of the panel control device 31.

[0026] FIG. 6 is a diagram showing an example of a product ID list 34 (RW ID list). The product ID list 34 is information that associates user ID reading units (IC card R / Ws) 32a, 32b,... provided for each product with the product. An RW ID that is information for identifying the user ID reading units (IC card R / Ws) 32a, 32b,... and a product ID that is information for identifying the product are associated with each other. For example, product ID "a" is associated with the IC card R / W (user ID reading unit) 32 with RW ID "01", product ID "b" is associated with the IC card R / W (user ID reading unit) 32 with RW ID "02", product ID "c" is associated with the IC card R / W (user ID reading unit) 32 with RW ID "03", and product ID "d" is associated with the IC card R / W (user ID reading unit) 32 with RW ID "04". In this way, when user ID reading units (IC card R / Ws) 32a, 32b,... are provided for each product, both the RW ID and the product ID can be said to be information for identifying the product.

[0027] The communication unit 313 of the panel control device 31 has a communication control device, a communication port, etc., and is a communication interface that mediates communication via the network 7. The panel control device 31 is communicatively connected to the server 6 etc. via the network 7 and can transmit and receive various data. The network 7 includes a LAN (Local Area Network), a WAN (Wide Area Network) communicatively connected over a wider area, or a public communication line such as the Internet. Area Network), or a public communication line such as the Internet.

[0028] The input unit 314 is, for example, a pointing device such as a keyboard or a mouse, or a touch panel provided integrally with the display, and inputs data to the control unit 311. The display unit 315 is composed of a display device such as a liquid crystal panel or a CRT monitor, and a logic circuit (such as a video adapter) for executing display processing in cooperation with the display device, and displays the input display data on the display device under the control of the control unit 311. The peripheral device I / F unit 316 is a port for connecting peripheral devices such as IC card R / Ws (user ID readers) 32a, 32b, ….

[0029] The IC card R / Ws (Reader / Writer) 32a, 32b, … perform data reading and writing with the IC card 2.

[0030] The product panel 3 holds the IC card 2 up to the user ID readers (IC card R / Ws) 32a, 32b, … provided respectively for the products or product images posted on the product posting section 30 by the purchaser, reads the user ID 251 stored in the IC card 2, and transmits the RW ID (or the product ID stored in association with the RW ID), which is the identification information of the user ID reader 32 that has read the information of the IC card 2, to the server 6 in association with the read user ID 251 as purchase plan information 621. In this embodiment, when the purchaser holds the IC card 2 up to the user ID reader (IC card R / W) 32 once, the user ID of the purchaser and the RW ID (product ID) are transmitted to the server 6 as the purchase plan information 621 for one product. When the purchaser holds the same IC card 2 up to the user ID reader (IC card R / W) 32 for the same product twice, the user ID of the purchaser and the RW ID (product ID) are transmitted to the server 6 as the purchase plan information 621 for two products. The server 6 additionally stores the information (user ID, product ID (or RW ID), quantity) transmitted from the product panel 3 (panel control device 31) in the purchase plan information 621 in the storage unit 62.

[0031] Next, the configuration of the server 6 will be described. As shown in FIG. 1, the server 6 is communicatively connected to a product panel 3 (product posting device) for posting products, a correction terminal 4, and a cash register terminal 5 via a network 7, and is a device for storing and managing purchase plan information 621 and settlement information 622 of each user in the sales system 1. The server 6 is composed of, for example, a computer or the like in which a control unit 601, a storage unit 602, a communication unit 603, an input unit 604, a display unit 605, a peripheral device I / F unit 606, etc. are connected via a bus 607. The configurations of the control unit 601, the storage unit 602, the communication unit 603, the input unit 604, the display unit 605, and the peripheral device I / F unit 606 are the same as those of the control unit 311, the storage unit 312, the communication unit 313, the input unit 314, the display unit 315, and the peripheral device I / F unit 316 of the panel control device 31, so the description thereof is omitted. However, the configuration of the server 6 can be appropriately changed according to the application.

[0032] In the sales system 1, the control unit 601 of the server 6 stores information (product ID or RW ID) for identifying a product transmitted from the product panel 3 and the user ID as purchase plan information 621 in the storage unit 602. Further, the control unit 601 of the server 6 generates settlement information 622 for each user and transmits it in response to a request from the cash register terminal 5. Details of these processes will be described later.

[0033] The storage unit 602 of the server 6 stores purchase plan information 621 and settlement information 622. The purchase plan information 621 is information in which records having data items of "user ID", "product ID (or RW ID)", "quantity", and "settlement" are accumulated as shown in FIG. 8(a). When information on the user ID, product ID (or RW ID), and quantity is transmitted from the panel control device 31 of the product panel 3, the control unit 601 of the server 6 adds a new record to the purchase plan information 621, and the received information on the user ID, product ID (or RW ID), and quantity is added to the data items "user ID", "product ID (or RW Enter and store them in "ID)" and "quantity" respectively. Also, the information of the data item "settlement" is stored as "uncompleted" until a settlement completion notification is received from the cash register terminal 5. In the example of Fig. 8, in the first record of the purchase plan information 621, the RW ID "a", quantity "1", and settlement "uncompleted" are stored in association with the user ID "0001". In the second record, the RW ID "a", quantity "1", and settlement "uncompleted" are stored in association with the user ID "0002". In the third record, the RW ID "b", quantity "1", and settlement "uncompleted" are stored in association with the user ID "0002". In the fourth record, the RW ID "c", quantity "2", and settlement "uncompleted" are stored in association with the user ID "0001". In this way, each time information on the user ID, product ID (or RW ID), and quantity is sent from the product panel 3, it is sequentially stored in the purchase plan information 621 of the server 6.

[0034] The settlement information 622 is information obtained by summarizing the uncompleted purchase plan information 621 for each user ID. As shown in Fig. 8(b), information on the user ID, product ID (or RW ID), and quantity is stored. When the server 6 receives a settlement information acquisition request together with the user ID 251 from the cash register terminal 5, it generates the settlement information 622 for the corresponding user ID 251 and returns it to the requesting cash register terminal 5. The cash register terminal 5 calculates the total amount based on the received settlement information 622 and the product price information 522 stored in the storage unit 502, and performs the settlement process.

[0035] Next, the configuration of the modification terminal 4 will be described. The correction terminal 4 is a terminal used when a purchaser checks or corrects the content of the purchase plan information 621 stored in the storage unit 602 of the server 6, and one or more units are installed in the venue. The correction terminal 4 is configured by, for example, a computer or the like in which a control unit 401, a storage unit 402, a communication unit 403, an input unit 404, a display unit 405, a peripheral device I / F unit 406, etc. are connected via a bus 407 as shown in FIG. 9. An IC card R / W, which is a user ID reading unit 41, is connected to the peripheral device I / F unit 406. The configurations of the control unit 401, the storage unit 402, the communication unit 403, the input unit 404, the display unit 405, and the peripheral device I / F unit 406 are the same as those of the control unit 311, the storage unit 312, the communication unit 313, the input unit 314, the display unit 315, and the peripheral device I / F unit 316 of the panel control device 31, so the description thereof is omitted. However, the configuration of the correction terminal 4 can be appropriately changed according to the application.

[0036] In the sales system 1, the control unit 401 of the correction terminal 4 reads the user ID 251 from the IC card 2 and acquires the purchase plan information 621 corresponding to the read user ID 251 from the server 6. The control unit 401 of the correction terminal 4 displays the acquired purchase plan information 621 on the display unit 405 so that the user can check it. Also, it accepts the correction of the purchase plan information 621 and transmits the corrected purchase plan information 621 to the server 6. Further, it is desirable that the control unit 401 of the correction terminal 4 calculates and displays the total amount of the products included in the purchase plan information 621. Details of these processes will be described later.

[0037] The same product ID list (RW ID list) 521 and product price information 522 as those stored in the cash register terminal 5 are stored in the storage unit 402 of the correction terminal 4 (see FIG. 11).

[0038] Next, the configuration of the cash register terminal 5 will be described. The cash register terminal 5 is a terminal used when a purchaser conducts accounting (settlement) for the products stored in the storage unit 602 of the server 6, and one or more units are installed in the venue. As shown in FIG. 10, for example, the cash register terminal 5 is configured by connecting a control unit 501, a storage unit 502, a communication unit 503, an input unit 504, a display unit 505, a peripheral device I / F unit 506, a change processing unit 507, a receipt printer 508, etc. via a bus 510. An IC card R / W, which is a user ID reading unit 51, is connected to the peripheral device I / F unit 506. However, the configuration of the cash register terminal 5 can be appropriately changed according to the application. Since the configurations of the control unit 501, the storage unit 502, the communication unit 503, and the peripheral device I / F unit 506 are the same as those of the control unit 311, the storage unit 312, the communication unit 313, and the peripheral device I / F unit 316 of the panel control device 31, the description thereof is omitted.

[0039] As shown in FIG. 11, a product ID list (RW ID list) 521 and product price information 522 are stored in the storage unit 502 of the cash register terminal 5 and the storage unit 402 of the correction terminal 4. As shown in FIG. 11(a), the product ID list 521 is information in which a product ID, which is information for identifying the products posted on the product panel 3, is associated with an RW ID, which is information for identifying the corresponding user ID reading unit 32 (IC card R / W) of the product panel 3. The product ID list 521 stored in the cash register terminal 5 and the correction terminal 4 stores the same data as the product ID list 34 (FIG. 6) stored in the product panel 3.

[0040] As shown in FIG. 11(b), the product price information 522 stores at least price information in association with the product ID as information regarding each product posted on the product panel 3.

[0041] The change processing unit 507 is a device that calculates and pays out the change amount based on the price of the product and the amount of money received. The input unit 504 includes an input device such as a numeric keypad or a keyboard, and inputs data to the control unit 401. The display unit 505 includes a main display used by the store clerk and a customer display having a display screen, and displays the display data input under the control of the control unit 501 on each display device. The receipt printer 508 is a printer that prints the names and prices of sold products, the amounts of deposits and change, etc. on a predetermined receipt paper. The IC card R / W 51 is a user ID reading unit 51 that reads the user ID 251 stored in the IC card 2 held by the purchaser. The IC card R / W 51 inputs the user ID read from the IC card 2 to the control unit 501.

[0042] The control unit 501 of the cash register terminal 5 acquires the settlement information 622 corresponding to the user ID 251 read from the IC card 2 from the server 6, calculates the total amount with reference to the product price information 522, and displays it on the display unit 505. Also, settlement processing is performed using cash, credit cards, electronic money, etc. Further, in the cash register terminal 5, it may be possible to modify the purchase plan information 621.

[0043] Next, with reference to FIG. 12, the functional configuration of the sales system 1 of the first embodiment will be described. As shown in FIG. 12, in the sales system 1, the product panel 3 includes a storage unit 312, a user ID reading unit 32, a purchase plan information transmitting unit 33, etc. A product ID list 34 (RW ID list) is stored in the storage unit 312. Also, the IC card 2 includes a storage unit 25 that stores the user ID 251. The server 6 includes a communication unit 61, a storage unit 602, a settlement information generation unit 63, a settlement information transmitting unit 64, a settlement completion processing unit 65, etc. The purchase plan information 621 and the settlement information 622 are stored in the storage unit 602.

[0044] The correction terminal 4 includes a storage unit 402, a user ID reading unit 41, a purchase plan information acquisition unit 42, a purchase plan information display unit 43, a correction unit 44, a correction information transmission unit 45, a total amount display unit 46, and the like. The cash register terminal 5 includes a user ID reading unit 51, a settlement information acquisition unit 52, a storage unit 502, a settlement processing unit 54, a settlement completion information transmission unit 55, and the like. In the storage unit 402 of the correction terminal 4 and the storage unit 502 of the cash register terminal 5, a product ID list (RW ID list) 521 and product price information 522 are stored (FIG. 11).

[0045] In the storage unit 312 of the product panel 3 (the storage unit 312 in FIG. 5), a product ID list (RW ID list) 34, which is a list of product IDs that are information for identifying each of one or more products or RW IDs that are information for identifying the user ID reading units 32 provided for the products, is stored.

[0046] When the user holds the IC card 2 over the user ID reading unit 32, the user ID reading unit 32 reads the user ID 251 stored in the IC card 2. The user ID reading unit 32 corresponds to the user ID reading units 32a, 32b, 32c,... in FIG. 1 and the IC card R / Ws 32a, 32b, 32c,... in FIG. 5.

[0047] The IC card 2 includes a storage unit 25 that stores the user ID 251. The storage unit 25 corresponds to the EEPROM 25 in FIG. 3.

[0048] The communication unit 61 of the server 6 transmits and receives data such as purchase plan information 621 and its correction information between the product panel 3 and the correction terminal 4. The storage unit 602 of the server 6 stores the purchase plan information 621 and the settlement information 622. The settlement information generation unit 63 extracts information using the user ID as a key from the purchase plan information 621 and generates settlement information for each user ID. The settlement information transmission unit 64 transmits the settlement information generated by the settlement information generation unit 63 to the cash register terminal 5. When the settlement completion processing unit 65 receives the settlement completion information transmitted from the cash register terminal 5, it performs processing to reflect the settlement completion information in the purchase plan information 621.

[0049] The user ID reading unit 51 of the cash register terminal 5 reads the user ID 251 stored in the IC card 2. The user ID reading unit 51 corresponds to the IC card R / W 51 in FIGS. 1 and 10. The settlement information acquisition unit 52 requests and acquires the settlement information 622 corresponding to the user ID 251 read by the user ID reading unit 51 from the server 6. The storage unit 502 of the cash register terminal 5 stores a product ID list (RW ID list) 521 which is a list of product IDs that are information for identifying each of one or more products or RW IDs that are information for identifying the user ID reading unit 32 provided for the product. Also, it stores product price information 522 which is the price information of each product (FIG. 11).

[0050] The settlement processing unit 54 calculates the total amount of the products included in the settlement information 622 based on the settlement information 622 acquired by the settlement information acquisition unit 52, product price information 522, etc., and performs settlement processing. When the settlement processing of the products is completed in the settlement processing unit 54, the settlement completion information transmission unit 55 transmits a notification of the completion of settlement to the server 6 and reflects the settlement completion information in the purchase plan information 621 stored in the storage unit 602.

[0051] Note that the cash register terminal 5 may be provided with a correction unit (not shown) that corrects the number, deletes, adds, etc. of the products included in the settlement information 622 acquired by the settlement information acquisition unit 52. In that case, the settlement processing unit 54 performs the settlement processing of the products based on the settlement information corrected by the correction unit.

[0052] The storage unit 402 of the correction terminal 4 stores a product ID list (RW ID list) 521, which is a list of product IDs that are information for identifying each of one or more products or RW IDs that are information for identifying the user ID reading unit 32 provided for the product. Further, it stores product price information 522, which is price information for each product (Fig. 11). The product ID list (RW ID list) 521 and the product price information 522 stored in the correction terminal 4 are the same as those stored in the cash register terminal 5.

[0053] The user ID reading unit 41 of the correction terminal 4 reads the user ID 251 stored in the IC card 2. The user ID reading unit 41 corresponds to the IC card R / W 41 in Figs. 1 and 9. The purchase plan information display unit 43 acquires the purchase plan information 621 of the user corresponding to the user ID 251 read by the user ID reading unit 41 from the server 6 and displays it on the display unit 405. The correction unit 44 accepts input of corrections to the purchase plan information 621 acquired from the server 6. For example, it accepts corrections such as deletion or addition of products, and change of quantity. The correction information transmission unit 45 transmits the content corrected by the correction unit 44 to the server 6 to update the purchase plan information 621 stored in the server 6. The total amount display unit 46 calculates the total amount of the products included in the purchase plan information 621 acquired by the purchase plan information acquisition unit 42 from the server 6 with reference to the product price information 522 stored in the storage unit 402 and displays it on the display unit 405.

[0054] Next, the processing flow in the sales system 1 of the first embodiment will be described. Fig. 13 is a flowchart showing the processing flow at the time of product selection.

[0055] In the product panel 3, the user (purchaser) holds the IC card 2 over the user ID reader (IC card R / W) 32 provided on the product they want (step S101). Then, the IC card 2 transmits the user ID 251 stored in the storage unit 25 to the user ID reader (IC card R / W) 32 (step S102). The control unit 311 of the panel control device 31 of the product panel 3 acquires the user ID 251 from the IC card 2 (step S103).

[0056] The control unit 311 of the panel control device 31 of the product panel 3 acquires the RW ID or product ID of the user ID reader (IC card R / W) 32 that has read the user ID 251 from the storage unit 312 (step S104). For example, when the user (purchaser) holds the IC card 2 over the user ID reader (RW ID "01") 32a provided on the product with product ID "a", the control unit 311 acquires the RW ID "01" of the user ID reader (IC card R / W) 32a, or refers to the product ID list 34 in the storage unit 312 to read the product ID "a" of the product corresponding to the RW ID "01" of the user ID reader (IC card R / W) 32a.

[0057] The control unit 311 (purchase plan information transmission unit 33) of the panel control device 31 of the product panel 3 transmits the user ID 251 acquired in step S103, the product ID or RW ID acquired in step S104, and the quantity information as purchase plan information 621 to the server 6 (step S105). Note that one touch of the IC card 2 is counted as one product.

[0058] When the server 6 receives the product ID or RW ID and its quantity (one for one touch) together with the user ID, it additionally stores the received information in the purchase plan information 621 in the storage unit 602 (step S106; see Fig. 8(a)). At this stage, the "settlement" item of the purchase plan information 621 is recorded as "not yet".

[0059] The user (purchaser) repeats the operation and holds the IC card 2 over the user ID reader 32 of the desired product. Each time, the panel control device 31 of the product panel 3 transmits the acquired user ID 251, the product ID (or RW ID), and the quantity information as the purchase plan information 621 to the server 6 and stores it in the server 6.

[0060] When the purchaser wants to check the details and quantity of the product sent to the server 6, the purchaser goes to the correction terminal 4 and can check and correct the details and quantity of the product with the correction terminal 4.

[0061] The correction process will be described with reference to FIG. 14. The user (purchaser) holds the IC card 2 over the reader 41 (IC card R / W 41) of the correction terminal 4 (step S201). Then, the user ID 251 stored in the IC card 2 is transmitted from the IC card 2 to the correction terminal 4 (step S202). The correction terminal 4 acquires the user ID 251 (step S203).

[0062] The control unit 401 (purchase plan information acquisition unit 42) of the correction terminal 4 transmits a purchase plan information acquisition request to the server 6 together with the user ID read from the IC card 2 (step S204). When the server 6 receives the purchase plan information acquisition request and the user ID from the correction terminal 4, it acquires the purchase plan information 621 corresponding to the received user ID from the storage unit 602 (step S205) and transmits it to the correction terminal 4 that is the request source (step S206). When the control unit 401 (purchase plan information display unit 43) of the correction terminal 4 receives the purchase plan information 621 (step S207), it displays the content of the purchase plan information 621 on the display unit 405. At this time, it is desirable for the control unit 401 (purchase plan information display unit 43) to display information such as the product information (product name, price, image, etc.), quantity, and total amount of the product included in the purchase plan information 621 on the display unit 405. In this case, in the storage unit 402 of the correction terminal 4, the product ID (RW It is assumed that product information such as the product name, price, and image of the product corresponding to [[ID=]] is stored. The control unit 401 (purchase plan information display unit 43) acquires the product information stored in the storage unit 402 and displays the product name, price, quantity, and image of the product included in the purchase plan information 621 on the display unit 405, and calculates and displays the total amount on the display unit 405.

[0063] The control unit 401 (modification unit 44) of the modification terminal 4 accepts the modification of the purchase plan information 621. The purchaser selects the product to be modified via the input unit 404 of the modification terminal 4 and changes the quantity, adds or deletes products (step S208). When the modification is made, the control unit 401 (total amount display unit 46) of the modification terminal 4 calculates the total amount of the products based on the modified content and displays it on the display unit 405 (step S209). The control unit 401 (total amount display unit 46) of the modification terminal 4 accepts the modification until the purchaser confirms the displayed total amount and an instruction to reflect the modified content is input (step S210; No → step S208). Each time the content of the purchase plan information 621 is modified, the control unit 401 (total amount display unit 46) of the modification terminal 4 calculates the total amount of the products and displays it on the display unit 405 (step S209).

[0064] After that, when the purchaser inputs an instruction to reflect the modified content (step S210; Yes), the control unit 401 (modified information transmission unit 45) of the modification terminal 4 transmits the modified purchase plan information 621 to the server 6 (step S211). When the server 6 receives the modified purchase plan information 621, it updates and stores the purchase plan information 621 in the storage unit 602 (step S212).

[0065] Next, the settlement process will be described with reference to FIG. 15. The user (purchaser) holds the IC card 2 over the user ID reader (IC card R / W) 51 of the cash register terminal 5 (step S301). Then, the user ID 251 stored in the IC card 2 is transmitted from the IC card 2 to the cash register terminal 5 (step S302). The cash register terminal 5 acquires the user ID 251 (step S303).

[0066] The control unit 501 (payment information acquisition unit 52) of the cash register terminal 5 transmits a payment information acquisition request to the server 6 together with the user ID read from the IC card 2 (step S304). When the server 6 receives the payment information acquisition request and the user ID 251 from the cash register terminal 5, it acquires the purchase plan information 621 corresponding to the received user ID 251 from the storage unit 602 and generates the payment information 622 (step S305). Then, it transmits the information to the cash register terminal 5 which is the request source (step S306). When the control unit 501 (payment information acquisition unit 52) of the cash register terminal 5 receives the payment information 622 (step S307), it performs payment processing based on the received payment information 622 (step S308). In step S308, the control unit 501 (payment processing unit 54) of the cash register terminal 5 acquires the price information corresponding to the product ID (RW ID) from the product price information 522 stored in the storage unit 502. Also, the control unit 501 (payment processing unit 54) calculates the total amount of the products based on the price and quantity of the products. The control unit 501 (payment processing unit 54) of the cash register terminal 5 displays the total amount on the display unit 505 to inform the purchaser. At the cash register terminal 5, payment processing is performed using cash, credit card, electronic money, etc. In the payment processing, a receipt on which the product name, quantity, price, total amount, change amount, etc. are printed is output from the receipt printer 508.

[0067] When the payment processing is completed, the control unit 501 (payment completion information transmission unit 55) of the cash register terminal 5 sends the payment completion information to the server 6 (step S309). The control unit 601 (payment completion processing unit 65) of the server 6 changes the "payment" item of the purchase plan information 621 stored in the storage unit 602 from "unpaid" to "paid" for the products for which the payment has been completed, or deletes the records of the products for which the payment has been completed from the purchase plan information 621 (step S310). The cashier hands the receipt output from the cash register terminal 5 to the purchaser and guides the purchaser to the product collection window. The purchaser goes to the product collection window and collects the purchased products all at once.

[0068] Note that the cash register terminal 5 can also accept corrections. In that case, the cash register terminal 5 executes the processes from step S201 to step S210 in FIG. 14. Then, in the settlement process of step S308, the settlement process is performed based on the corrected settlement information 622.

[0069] As described above, according to the sales system 1 of the first embodiment, the product panel 3 provided with the user ID reading unit 32 for each product is provided. When the purchaser holds the IC card 2 over the user ID reading unit (IC card R / W) 32 corresponding to the product they want, the identification information (product ID or RW ID) of the product is transmitted to the server 6 together with the user ID 251 and stored as the user's purchase plan information 621. At the cash register terminal 5, the settlement information 622 corresponding to the user ID 251 read from the IC card 2 is acquired from the server 6, the total amount of the products is calculated based on the price information of the products, etc., and the settlement process is performed. As a result, with just one operation of the purchaser holding the IC card 2 over the product (the user ID reading unit 32) they want, both the designation of the product and the recording of the product ID can be performed. Therefore, the purchaser does not need to take notes on the products they want or verbally inform the cashier, and the purchase of the products becomes smooth. Also, since the purchase plan information 621 is written to the server 6, only the user ID needs to be stored in the IC card 2, and it can be used regardless of the storage capacity of the IC card 2.

[0070] Note that in the above description, each time the user (purchaser) performs the operation of holding the IC card 2 over the user ID reading unit 32 of the product they want, the panel control device 31 of the product panel 3 acquires the user ID 251, and the information of the user ID, product ID (or RW ID), and quantity is transmitted to the server 6 and stored in the server 6 as the purchase plan information 621. However, the procedure is not limited to this. For example, when the user continuously holds the IC card 2 over a plurality of products (user ID reading units 32), the information of the product ID (or RW ID) and quantity may be transmitted to the server 6 together with the user ID in a lump for those products.

[0071] [Second Embodiment] Next, a second embodiment of the present invention will be described. The overall configuration of the sales system 1A according to the second embodiment is shown in FIG. 16. As shown in FIG. 16, the sales system 1A according to the second embodiment includes a card (hereinafter referred to as the QR card 2A) on which a code such as a QR code (registered trademark) is printed, and user ID reading units 37a, 37b, 37c,... that read the user ID 251 recorded on the QR card 2A.

The settlement processing unit 54 calculates the total amount of the products based on the settlement information 622 and the product information 531 acquired by the settlement information acquisition unit 52, and performs the settlement process. When the settlement process of the product is completed in the settlement processing unit 54, the settlement completion information transmission unit 55 transmits a notice of the completion of the settlement to the purchase plan information 621 stored in the server 6, and reflects the information on the completion of the settlement.

[0098] Next, referring to the flowchart of FIG. 22, the flow of the process at the time of product selection in the third embodiment will be described.

[0099] When the user (purchaser) starts the application and inputs an instruction to display the purchase screen 851, the control unit 801 (product display unit 84) of the mobile terminal 8 displays the purchase screen 851 as shown in FIG. 23 on the display unit 805 of the mobile terminal 8 (step S401). On the purchase screen 851, product images 851a, 851c of the products to be sold, purchase buttons 851b, 851d to be operated when wishing to purchase, etc. are displayed. In addition to the product images 851a, 851c, it is desirable that information such as the name, description, and price of the product be displayed on the purchase screen 851. The information on the products displayed on the purchase screen 851 is stored as product information 82 in the storage unit 802. It is assumed that when the control unit 801 of the mobile terminal 8 starts the application, it accesses the server 6, receives the latest product information 82 (623) from the server 6, and updates and stores it in the storage unit 802. The control unit 801 (purchased product input unit 85) accepts the selection of the product from the user on the purchase screen 851 (touch operation of the purchase buttons 851b, 851d).

[0100] When the user selects the desired product and enters the quantity (step S402), the control unit 801 (purchase plan information transmission unit 86) of the mobile terminal 8 transmits the product ID and quantity of the selected product together with the user ID to the server 6 (step S403). When the server 6 receives the product ID, quantity, and user ID, it adds a new record to the purchase plan information 621 in the storage unit 602, and inputs and stores the received user ID, product ID, and quantity in the data items "user ID", "product ID", and "quantity". The "settlement" item is stored as "not yet" at this stage (step S404; Fig. 21(a)).

[0101] By performing the correction process of Fig. 24, the user (purchaser) can check and correct the purchase plan information 621 stored in the server 6. Hereinafter, the correction process will be described with reference to Figs. 24 and 25.

[0102] When the user (purchaser) inputs a display instruction for the purchase plan information 621 to the mobile terminal 8 (step S501), the control unit 801 (purchase plan information acquisition unit 87) of the mobile terminal 8 transmits a purchase plan information acquisition request to the server 6 together with the user ID 81 stored in the storage unit 802 (step S502). In response to the purchase plan information acquisition request from the mobile terminal 8, the server 6 acquires the purchase plan information 621 corresponding to the user ID 81 from the storage unit 602 (step S503) and transmits it to the mobile terminal 8 (step S504).

[0103] When the control unit 801 of the mobile terminal 8 receives the purchase plan information 621 (step S505), it displays the received purchase plan information 621 on the correction screen 853 (step S506). As shown in FIG. 25, on the correction screen 853, images 853a and 853c of the products included in the purchase plan information 621 are displayed, and a purchase button 853b operated when making an additional purchase, a delete button 853d operated when deleting, a quantity change input field (not shown), etc. are also displayed. In addition to the images 853a and 853c of the products, it is desirable to display information such as the name, description, and price of the products on the correction screen 853. Further, the control unit 801 may calculate the total amount of the products included in the purchase plan information 621 based on the product information 82 stored in the storage unit 802 and display it on the correction screen 853.

[0104] The control unit 801 (correction unit 88) of the mobile terminal 8 accepts the input of corrections. The purchaser selects the product to be corrected, changes the quantity, or adds or deletes products via the input unit 804 of the mobile terminal 8 (step S507). When a correction is input, the control unit 801 of the mobile terminal 8 calculates the total amount of the products based on the corrected content and displays it on the display unit 805 (step S508). The control unit 801 accepts corrections until an instruction is input to reflect the corrected content after the purchaser confirms the displayed total amount (step S509; No). Each time the content of the purchase plan information 621 is corrected by the control unit 801 of the mobile terminal 8, the control unit calculates the total amount of the products and displays it on the display unit 405.

[0105] After that, when the purchaser inputs an instruction to reflect the corrected content (step S509; Yes), the control unit 801 (correction information transmission unit 89) of the mobile terminal 8 transmits the corrected purchase plan information 621 to the server 6 (step S510). When the server 6 receives the corrected purchase plan information 621, it updates and stores the purchase plan information 621 in the storage unit 602 (step S511).

[0106] Next, the settlement process in the sales system 1B of the third embodiment will be described with reference to FIG. 26. First, the user operates the mobile terminal 8 to display a QR code (registered trademark) 855 indicating the user ID 81 on the display unit 805. The control unit 801 (QR code (registered trademark) display unit 83) of the mobile terminal 8 converts the user ID 81 stored in the storage unit 802 into the form of a QR code (registered trademark) and displays it on the display unit 805 (step S601). FIG. 27 is a diagram showing an example of a state in which the QR code (registered trademark) 855 is displayed on the display unit 805 of the mobile terminal 8. Note that the user ID 81 may be displayed together with the QR code (registered trademark) 855 on the display unit 805. This enables the user ID 81 to be manually input to the cash register terminal 5 in case of a problem occurring in the code reading unit 57 or the like.

[0107] The user (purchaser) holds the QR code (registered trademark) 855 displayed on the mobile terminal 8 in front of the code reading unit 57 of the cash register terminal 5 (step S602). The code reading unit 57 of the cash register terminal 5 reads the QR code (registered trademark) 855 and acquires the user ID 81 (step S603).

[0108] The control unit 501 (payment information acquisition unit 52) of the cash register terminal 5 transmits a payment information acquisition request to the server 6 together with the acquired user ID (step S604). When the server 6 receives the payment information acquisition request and the user ID 81 from the cash register terminal 5, it acquires the purchase plan information 621 corresponding to the received user ID 81 from the storage unit 602 and generates payment information 622 (step S605). Then, it transmits the payment information 622 to the cash register terminal 5 that is the request source (step S606). When the control unit 501 (payment information acquisition unit 52) of the cash register terminal 5 receives the payment information 622 (step S607), it performs payment processing based on the received payment information 622 (step S608). The control unit 501 (payment processing unit 54) of the cash register terminal 5 acquires price information corresponding to the product ID included in the payment information 622 from the product information 531 stored in the storage unit 502. Also, the control unit 501 (payment processing unit 54) calculates the total amount of the products based on the price and quantity of the products. The control unit 501 (payment processing unit 54) of the cash register terminal 5 displays the total amount on the display unit 505 to inform the purchaser. At the cash register terminal 5, payment processing is performed using cash, a credit card, electronic money, or the like. In the payment processing, a receipt on which the product name, quantity, price, total amount, change amount, etc. are printed is output from the receipt printer 508.

[0109] When the payment processing is completed, the control unit 501 (payment completion information transmission unit 55) of the cash register terminal 5 sends the payment completion information to the server 6 for reflection (step S609). For example, the control unit 601 of the server 6 changes the "payment" item of the purchase plan information 621 stored in the storage unit 602 from "unpaid" to "paid" for the products for which the payment has been completed. Alternatively, the record of the products for which the payment has been completed is deleted from the purchase plan information 621 (step S610). The cashier hands the receipt to the purchaser and guides the purchaser to the product collection window.

[0110] The purchaser goes to the product collection window and receives the purchased products all at once.

[0111] Note that at the cash register terminal 5, it is also possible to accept corrections to the products included in the payment information 622. In that case, the cash register terminal 5 executes the processes from step S501 to step S510 in FIG. 24. Then, in the payment process of step S608, the cash register terminal 5 performs the payment process based on the corrected payment information 622.

[0112] As described above, according to the sales system 1B of the third embodiment, the user can select the products to be purchased with the mobile terminal 8. Information on the selected products and quantities is transmitted to the server 6 and managed by the server 6 as the planned purchase information 621. Also, when making a payment for a product, the user ID 81 is input to the cash register terminal 5 by displaying a QR code (registered trademark) 855 indicating the user ID 81 on the display unit 805 of the mobile terminal 8 and reading it with the code reading unit 57 of the cash register terminal 5. The cash register terminal 5 can obtain the payment information 622 corresponding to the user ID 81 from the server 6 and perform the payment. As a result, while the user is standing in line at the cash register at the sales venue for goods or the like, the user can select the desired products with the mobile terminal 8 and transmit them to the server 6 in advance, and at the cash register terminal 5, by simply displaying the QR code (registered trademark) 81 on the mobile terminal 8 and having it read, the user can smoothly make the payment for the products and receive the products. The purchaser does not need to walk around the venue to select the desired products or verbally tell the cashier the desired products, and the purchase of the products becomes smooth. Also, in the third embodiment, unlike the sales system 1 of the first embodiment and the sales system 1A of the second embodiment, it is not necessary to provide the product panel 3 or the correction terminal 4, and it is not necessary to arrange a reading unit (IC card R / W or code reader) for each of the displayed products, so the device configuration can be simplified and the cost can be reduced.

[0113] As described above, the preferred embodiments of the present invention have been described with reference to the accompanying drawings, but the present invention is not limited to such examples. It is obvious that those skilled in the art can conceive of various modification examples or correction examples within the scope of the technical idea disclosed in this application, and it is naturally understood that those also belong to the technical scope of the present invention.
