Description

  The present invention is widely used in jewelry stores that sell watches and jewelry, stores that handle bags and bags, clothing stores, and cooked food stores that sell cooked foods such as bakery stores, confectionery stores, and side dish stores. The present invention relates to a price clearing system and a price clearing method for products that can be used and utilized over the years. In describing the present invention, a cooked food store that handles cooked food will be described as an example. In particular, the cooked foods such as baked bread and confectionery are displayed, and the customers can display the cooked foods on display in a self-service tray and take them to the payment counter. It will be introduced into a so-called cafeteria-style cooked food retailer (including a retailer who takes home cooked food), and will be explained in an easy-to-understand manner using a suitable cooked food billing system and method.

  In traditional food stores such as bakery stores and confectionery stores, cooked foods such as baked bread and confectionery are unwrapped and displayed on open shelves, and customers can self-use the displayed cooked foods. There is a so-called cafeteria-type store where a service is placed on a tray and taken to a place where payment is made, and a clerk pays for the payment.

A price settlement system using an IC tag has been proposed as a price settlement system for cooked food at such cooked food stores (for example, Patent Document 1). In this system, an IC tag is attached to a package of cooked food, information such as the product name and price of the cooked food written on the IC tag is read by an IC tag reader, and the price is settled based on the read information. . According to the payment system using this IC tag, it is possible to efficiently and accurately perform payment of cooked food in a short time.
JP 2007-293724 A

  In the above-described payment settlement system, conventionally, an IC tag attached to a cooked food is often discarded after being used only once. However, even though the unit price of the IC tag is cheaper than before, if the IC tag is discarded without being collected, the same number of IC tags as the number of cooked foods to be sold will be discarded. Will increase. Therefore, if the IC tag can be reused, the number of newly purchased IC tags can be reduced and the cost can be reduced. Therefore, in the above-described payment settlement system, a new technology for promoting the reuse of the IC tag is proposed. There is a need.

  When an IC tag once attached to a product is removed and reused, the information written in the IC tag and the information of the newly attached product need to be exactly matched. If an IC tag that is replaced with another product without confirming the coincidence of this information is used, the actual product and the information do not match at the time of payment, which may lead to a trouble.

  Therefore, in the past, when the collected IC tag is reused, the information stored in the IC tag is confirmed using the training mode of the payment settlement device, etc., and the storage location of the IC tag is managed separately for each product. Was. Then, when attaching the IC tag to other cooked food, the IC tag is selected from the storage location corresponding to the corresponding cooked food. However, in this method, it takes a lot of time to confirm and sort the information written on the IC tag, and in addition to the information confirmation mistake, the IC tag sorting management mistake, and the IC tag attachment mistake. There is a possibility that the reliability of the payment system using the IC tag may be impaired.

  In addition, when writing information on cooked food on an IC tag using an IC tag reader / writer device connected to the host computer, a printed label that allows visual confirmation of the information written on the IC tag is attached to the IC tag. At present, the label is separately printed by a device different from a series of devices including an IC tag reader / writer device connected to a host computer. For this reason, troubles such as a mistake in attaching a label to the IC tag may occur. In that case, the cooked food purchased by the customer and the information on the IC tag attached to the cooked food do not match, so there is a difference between the total amount planned by the customer at the time of accounting and the billed amount presented. In addition to inconvenience, it could cause problems such as a decline in store credit.

  SUMMARY OF THE INVENTION The present invention has been made in view of the above points, and an object of the present invention is to provide a product price settlement system capable of easily and accurately writing information to an IC tag and efficiently reusing the IC tag. The purpose is to provide a payment method.

  In order to solve the above-described problems, a product price settlement system according to the present invention includes an IC tag in which information including at least identification information related to a product is written, an IC tag attaching / detaching unit that allows the IC tag to be attached to and detached from the product, An IC tag reader / writer that stores a plurality of product data including at least product identification information and a price and communicates with an IC tag to read and write information. A price calculation means for calculating the price of the product based on the information written in the IC tag read by the IC tag reader / writer, and an IC tag for writing the information based on the product data to the IC tag via the IC tag reader / writer And writing means.

  In the present invention, both the price settlement means for reading the IC tag information to settle the price and the IC tag writing means for writing information to the IC tag are provided in the price settlement apparatus. Price settlement processing can be performed at the same time, and information can be written to the IC tag by the IC tag writing means after the price settlement. As a result, the IC tag once attached to the product can be replaced with another product and reused (recycled). In addition, since the settlement of the price of the product and the recycling of the IC tag can be realized with one price settlement system, the recycling of the IC tag can be promoted without introducing a separate IC tag writing device or system. In addition, since data of a plurality of IC tags can be written together, necessary operations are simplified, and the IC tags can be reused efficiently.

  Further, in the price settlement system for the above-mentioned product, the price settlement apparatus includes an information storage unit that stores information about the product, and a reading unit that reads information about the product stored in the information storage unit. The means may be provided with a printed matter output means for writing information on the product read by the reading means to the IC tag and outputting a printed matter on which information about the product read by the reading means is printed.

  According to this configuration, when the information is written to the IC tag by the payment settlement apparatus, a printed matter on which the information to be written is printed can be output. Therefore, by attaching the printed matter to the IC tag, it is possible to visually confirm the information written on the IC tag, and it is possible to prevent human error such as a mistake in the IC tag. Further, even when an IC tag reading failure occurs during the price settlement, the price settlement can be performed based on the print information, so that the merchandise price settlement process can be performed smoothly.

  In addition, the commodity price settlement system includes IC tag counting means for placing the IC tag on the tray and counting the IC tag placed on the tray, and the printed matter output means includes the IC tag counting means. The same number of printed matter as the counted IC tags may be output.

  According to this configuration, by counting the number of IC tags placed on the tray when printing product information, the same number of printed matter as the number of IC tags to which information is written can be created. Thereby, since the printed matter can be attached to all the IC tags in which information is written, the information written in the IC tag and the printing information attached to the IC tag can be made to correspond exactly one-on-one. In addition, even if an information writing failure to the IC tag occurs, the presence of the defective IC tag can be detected from the collation result between the written data and the printed matter.

  Moreover, in the price settlement system for merchandise described above, the IC tag may include a printed material mounting unit that mounts the printed material output by the printed material output means in a state where the printed content is visible from the outside.

  When information on an IC tag is written and reused, information on another product different from the information currently written is often written on the IC tag. Therefore, even if an IC tag is mistaken, it is necessary to be able to find the mistake when attaching the IC tag to the product or when paying for the price. Therefore, the IC tag is provided with the printed matter mounting portion. According to this, since the operator of the system can visually confirm the information written in the IC tag when the IC tag is attached or when the payment is settled, it is possible to prevent human error caused by the IC tag misuse. Become.

  The printed matter output means may output a printed matter on which at least the product name, price, and code information of the product are printed as information about the product.

  According to this, even when an IC tag reading failure or the like occurs, it is possible to pay for the product using the product name, price, and code information printed on the printed matter attached to the IC tag. Checkout can be done without delay. As a result, the payment settlement process can be performed smoothly without the system operator being confused.

  In addition, according to the present invention, a method for paying for a product stores a plurality of product data including at least product identification information and a price, and attaches an IC tag in which information including at least identification information about the product is written to the product. The IC tag reader / writer that communicates with the IC tag to read / write information reads the information on the IC tag, calculates the price of the product based on the read information, and stores the product data in the IC tag with the IC tag reader / writer. Based on this, information is written.

  According to this method, after paying for the product, information can be written to the IC tag based on the product data, so the IC tag once attached to the product can be replaced with another product and reused. (Recycling) becomes possible. In addition, payment for goods and recycling of IC tags can be performed in a series of processes, so there is no need to separate IC tags in a separate process using a separate IC tag writing device or system. Can be performed efficiently. Further, when data is written to the IC tag, if the data is written collectively to the plurality of IC tags, necessary operations are simplified, and the IC tag can be recycled more efficiently.

  According to the price settlement system and the price settlement method for goods according to the present invention, both the price calculation by the IC tag and the writing of information to the IC tag can be easily and accurately performed by one system or a series of methods. The recycling of IC tags can be promoted while maintaining the convenience of price calculation by.

On the other hand, in addition to the product code, product name, and price of each product, the inventory management data 76 records data such as the number of IC tags created, the number sold, the current inventory number, the IC tag creation start number, and the IC tag creation date and time. Has been. Even in the inventory management data 76, each product is given a barcode. Each product is assigned an inventory control number. Here, the proper number of IC tag creations defines an upper limit (number) of IC tag creations. Further, the current inventory number indicates the number of IC tags 30 prepared for attachment to the bread 10 on which the IC tags 30 displayed on the display shelf 103 are attached and the cooked food that has been cooked. The IC tag creation start number indicates the reference number for instructing the start of IC tag creation when the creation of the IC tag 30 (writing of information to the IC tag 30) is automatically performed as described later.

  Here, a procedure from the preparation stage of displaying the finished bread 10 on the display shelf 103 until the customer (purchaser) purchases the bread 10 and finishes the payment settlement procedure will be described. FIG. 9 is a flowchart for explaining this procedure. First, the clerk baked the bread 10 in the back room 102 shown in FIG. 1 and put the baked bread 10 in the bread storage bag 20 on the work table 108. In addition, the product data (product name, product price) of the bread 10 is written in the IC tag 30 in advance by the IC tag reader / writer 61 or the like. At the same time, a name tag receipt 35 shown in FIG. 4 is issued by a receipt issuing unit 62 c or the like, and the name tag receipt 35 is mounted on the receipt mounting unit 34 of the IC tag 30. The IC tag 30 is attached with the clip 40 in the vicinity of the opening 23 of the bread storage bag 20 (step ST1). Next, the store clerk classifies the bread 10 contained in the bread storage bag 20 by type and displays it on the display shelf 103 while the opening 23 of the bread storage bag 20 remains open (step ST2).

  The customer who has selected the bread 10 displayed on the display shelf 103 places the bread 10 on the tray 64 together with the bread storage bag 20 to which the IC tag 30 is attached (step ST3). When the customer places the selected bread 10 on the tray 64, the customer brings the tray 64 to the bill settlement place 104 and places it on the tray placement surface 63 of the IC tag reader / writer 61 as shown in FIG. 5 (step ST4). .

  When the tray 64 on which the pan 10 is placed is placed on the tray placement surface 63, information on the IC tag 30 is read by the antenna 65 (step ST5). The read information is transmitted to the register 62. The CPU 600 of the register 62 reads the product master data 75 in which product information (product name, price, code information) that matches the received information is stored, and calculates the total price of the bread 10 on the tray 64 based on the product master data 75. To display. When the clerk receives the price from the customer and performs the closing operation with the register 62, a receipt printed with the details of the price settlement is issued by the receipt issuing unit 62c. This completes the payment settlement procedure (step ST6). At this time, the inventory management data 76 corresponding to the cooked food that has been settled is read out, and the sold quantity is added, and the sold quantity is subtracted from the current inventory quantity. At this time, the store clerk removes and collects the IC tag 30 attached to the bread storage bag 20 of the bread 10 that has been paid for (step ST7). Further, the store clerk removes the IC tag 30 from the bread storage bag 20 and puts the bread 10 together with the bread storage bag 20 in a take-out outer bag (not shown) and hands it to the customer (step ST8).

  Furthermore, in the price settlement system of the present embodiment, the product information of the IC tag 30 removed from the bread storage bag 20 can be written after the above price settlement procedure is completed. Hereinafter, this procedure will be described in detail with reference to the flowchart of FIG. Here, a case where writing of the IC tag 30 (creation of the IC tag 30) is performed manually will be described. First, when the clerk presses the IC tag / recycle button 70a on the menu screen of the clerk-side display unit 62b, the payment settlement apparatus 60 switches to the IC tag recycle mode (step ST10), and the display example of FIG. It is displayed on the side display part 62b. In the example shown in FIG. 11, the product data 80 displayed on the store clerk side display unit 62b includes information on a product code, an identification code, a product name, and a product price.

  Subsequently, the store clerk places the tray 64 on which the IC tag 30 removed from the bread storage bag 20 in step ST7 is placed on the tray placing surface 63 (step ST11). At this time, a plurality of IC tags 30 can be put together on the tray 64. In this state, the product data scheduled to be written to the IC tag 30 is called (step ST12). Touch the button written as the barcode of the product data 80 displayed on the store clerk side display unit 62b, and the product to be written this time from the code book that contains the barcode and the product name that calls the data of each cooked food The barcode corresponding to the data is read using the scanner 62d, and the product data to be written is called by pressing the input button 82. At this time, the number of IC tags 30 on the tray 64 is counted by the CPU 600 based on the data obtained through the IC tag reader / writer 61 (step ST13). Thereafter, the called product data and the counted number of IC tags 30 on the tray 64 are displayed on the store clerk display section 62b (step ST14).

  Further, the store clerk side display unit 62b is provided with an execution button 81 for executing the operation of writing the product data 80 into the IC tag 30. When the execution button 81 is pressed (step ST15), information on the product data 80 is written to the IC tag 30 on the tray 64 (step ST16). In this way, the product information data stored in the IC tag 30 is written. The store clerk display 62b is provided with an input button 82 and an end button 83.

  Thereafter, the receipt issuing unit 62c prints and issues the name tag receipt 35 on which the information of the product data 80 is printed (step ST17). FIG. 12 is a diagram showing an example of the name tag receipt 35 to be issued. The same number of name tag receipts 35 as the IC tags 30 on the tray 64 are output at a time. The name tag receipt 35 at this time is issued in a state where the name tag receipts 35 are connected in a strip shape as shown in FIG. In order to facilitate the separation of the name tag receipts 35, only one of the left and right ends from the front of the receipt is left, and the position indicated by the broken line 35b is cut to form a horizontally long strip. It is easy to handle because it is in a continuous state without falling apart. Further, a perforation may be put at the position of the broken line 35b. Further, the name tag receipt 35 is in the form of a horizontally long strip as shown in FIG. When the name tag receipt 35 is folded into a mountain fold at a folding line 35a provided in the center, the same print is displayed on both the front and back surfaces. If the name tag receipt 35 in this state is mounted on the receipt mounting portion 34 of the IC tag 30, the print contents can be viewed from both the front and back surfaces of the IC tag 30.

  When the writing of the product data to the IC tag 30 is completed, the store clerk lowers the tray 64 on which the IC tag 30 is placed from the tray placement surface 63 (step ST18). On the other hand, the name tag receipts 35 that are connected are separated one by one. Then, the name tag receipt 35 is attached to the receipt attaching portion 34 of the IC tag 30 (step ST19). As a result, the IC tag 30 can be attached to a different type of bread 10 and can be used.

  As described above, according to the price settlement system of the present embodiment, the price settlement apparatus 60 reads the information of the IC tag 30 and settles the price, and the IC tag writing function that writes information to the IC tag 30 Therefore, when the price of the bread 10 is settled, the price settlement function can be used for the price settlement process, and after the price settlement, the information is written to the IC tag 30 by the IC tag rewrite function. It is possible to reuse (recycle) the IC tag 30 attached to the bread 10 by replacing it with another kind of bread 10. In this way, the payment of the bread 10 and the recycling of the IC tag 30 can be realized with a single payment system, and therefore the recycling of the IC tag 30 is promoted without introducing a separate IC tag writing device or system. be able to. Further, when information is written to the IC tag 30, a plurality of IC tags 30 can be placed on the tray 64 at a time, and data of the plurality of IC tags 30 can be written together. Thereby, necessary operations are simplified, and the IC tag 30 can be efficiently recycled.

  Further, in this price settlement system, when the information written in the IC tag 30 is written by the price settlement apparatus 60, the name tag receipt 35 on which the written information is printed can be output. By attaching the name tag receipt 35 to the IC tag 30, it becomes possible to visually confirm the information written in the IC tag 30, so that human error such as a mistake in the IC tag 30 can be prevented in advance. it can. Further, even when a reading failure of the IC tag 30 occurs during the payment settlement, the payment settlement can be performed smoothly based on the information printed on the name tag receipt 35, so that the payment settlement process can be performed smoothly.

  In this embodiment, the IC tag 30 attached to the bread storage bag 20 is removed and collected after the payment is settled, and the collected IC tags 30 are put together on the tray 64 to write product information of the IC tag 30. Although the case where it carries out was demonstrated, besides this, it is possible to write the product information of the IC tag 30 by the following method. That is, the IC tag 30 is placed in the bread storage bag 20 containing the bread 10 placed on the tray 64 after the payment of the bread 10 in step ST6 shown in FIG. At the stage of wearing, the product information regarding the other bread 10 is written into the IC tag 30. At the same time, a name tag receipt 35 on which the product information is printed is issued.

  According to this method, when the payment of the bread 10 on the tray 64 is completed, information on the new bread 10 has already been written in the IC tag 30 attached to the bread storage bag 20 on the tray 64. It becomes a state. Therefore, after the payment settlement procedure is completed, the IC tag 30 is removed from the bread storage bag 20 and collected, and if a name tag receipt 35 on which new product information is printed is attached to the IC tag 30, the information is stored in the IC tag 30. Writing is completed. This eliminates the need to write information to the IC tag 30 in a separate operation from the payment settlement procedure, so that it is possible to prevent inconveniences such as mistakes in operation associated with writing information to the IC tag 30 beforehand. The possibility of writing unnecessary product information or incorrect product information into the IC tag 30 is reduced.

  Further, according to this method, it is possible to automatically create a new IC tag 30 by writing the information of the IC tag 30 when the payment of the bread 10 on the tray 64 is completed. The procedure for automatically creating the IC tag 30 will be briefly described. For example, in the example shown in FIG. 8, in the case of AMPAN of the inventory management number 10001, the current inventory quantity and the IC tag creation start quantity are the same (both 5). When the IC tag 30 is created automatically, the creation of the IC tag 30 is started when the current inventory quantity becomes equal to or less than the IC tag creation start quantity. When the creation of the IC tag 30 is completed, the number of the created IC tags 30 is added to the current stock quantity. In addition to creating the IC tag 30 based on the number of breads 10 displayed on the display shelf 103, the IC tag 30 may be created according to the completion of the bread 10. In that case, the same number of IC tags 30 as the finished bread 10 may be created.

  Further, when the information of the IC tag 30 is written, based on the inventory management data 76, the bread 10 that is expected to be short on the display shelf 103 in the future (different from the bread 10 on which the IC tag 30 is currently mounted on the tray 64). By reading the information on the type of bread 10) from the inventory management data 76 and writing it in the IC tag 30, priority will be given to the writing of product information relating to the bread 10 which is currently selling well, so that a lot of bread 10 which will sell well will be sold in the future Even in this case, it is possible to prevent the IC tag 30 attached to the pan 10 from being insufficient. Here, in addition to selecting the data to be written to the IC tag 30 based on the inventory management data 76 as described above, instead of the inventory management data 76, it is based on order data for the bread 10 or cooking completion data for the bread 10. Data to be written to the IC tag 30 may be selected.

  Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and various modifications can be made within the scope of the technical idea described in the claims and the specification and drawings. Is possible. For example, the IC tag reader / writer 61 is not limited to the stationary type shown in the above embodiment, and may be a handy type as long as it has a communication range and a communication distance capable of communicating with the IC tag 30 on the tray 64. An IC tag reader / writer or the like may be used. In that case, information is read and written by holding a hand-held IC tag reader / writer over the IC tag 30 from above the tray 64.

  Since the IC tag 30 is attached to the bread storage bag 20 with a detachable clip 40, in addition to the price settlement method shown in the above embodiment, the IC tag 30 is preliminarily removed from the bread storage bag 20 at the time of price settlement. It is also possible to remove 30 and place only the IC tag 30 on the tray placement surface 63 of the IC tag reader / writer 61. Further, the data stored in the IC tag 30 may be only the price information of the bread 10.

  In the above embodiment of the present invention, the product master data 75 stored in the register 62 itself is stored in the CPU 600 of the register 62 based on the read information of the IC tag 30. The total price of the bread 10 on the tray 64 is calculated, but the product master data 75 is not stored in the register 62 itself, and all product information necessary for accounting is stored in the IC tag 30. Even if there is no product master data 75, the total price of the bread 10 on the tray 64 may be calculated. In this case, the inventory management data 76 is stored in the register 62 itself for automatically writing the product information to the IC tag 30, and information such as price necessary for accounting is displayed on the clerk side display section when the IC tag recycling is selected. A method of writing product information to the IC tag 30 is used based on the information indicated by the product data 80 of FIG. 11 displayed in 62b and the information of the inventory management data 76 for managing the inventory of the IC tag 30. As a result, the mechanism for writing the product information into the IC tag 30 can be simplified.

  In addition, the cooked food sales shop that introduces the price settlement system of the present invention displays unwrapped cooked food, and the customer selects the displayed cooked food and carries it on the tray 64 by self-service to the price settlement place. If it is a cafeteria-type food sales store, the type of cooked food handled is not limited to bread. For example, confectionery handled at a confectionery store or side dish handled at a side dish store may be used as a cooked food. Also, various cooked foods can be applied as the cooked food of the present invention. In the above-described embodiment of the present invention, cooked food is taken up and explained as a product to be sold. However, the price clearing system and the price clearing method according to the present invention are not limited to cooked food, for example, watches and jewelry. Any store that attaches an IC tag to a product and performs accounting settlement may be widely used without being limited to the product to be sold. In addition, when the product is cooked food, the IC tag cannot be directly attached to the product, so the IC tag is attached to the container for storing the product, but the IC tag is attached to the product such as a watch or jewelry. As a means, you may attach to goods using a string etc.
