Description

  The present invention relates to a commodity settlement system used in retail stores and the like. In particular, the present invention relates to a product settlement system that reads a product code from a radio tag (RFID (Radio Frequency Identification) tag) attached to a product and processes product sales data based on the read product code. The present invention also relates to a mobile terminal device used in the merchandise settlement system. Further, the present invention relates to the product settlement method.

  Mass merchandise stores such as supermarkets are equipped with product containers such as shopping baskets and shopping carts for customers. The customer who visits the store holds the shopping basket or pushes the shopping cart, goes around the store, puts the products to be purchased together in the shopping basket or the shopping cart, and transports them to the checkout place. A settlement device called a POS (Point Of Sales) terminal equipped with a barcode reader is installed at the checkout location. The store clerk (casher) takes out the products put in the product container one by one and reads the barcode attached to the product, thereby inputting the product information to the settlement apparatus. When the input of all the product information stored in the product container is completed, the total amount is displayed on the display unit of the settlement apparatus. The store clerk notifies the customer of the total amount, and the customer pays the price and receives a receipt.

  In the method in which the store clerk takes out the products one by one from the product container and inputs the product information to the payment apparatus, there is a problem that the input work takes time and the clerk's fatigue increases because the take-out operation is repeated. is there.

  In order to solve such a problem, a settlement apparatus including a wireless tag reader (wireless tag reader) that reads data from a wireless tag has been proposed. The wireless tag stores a product identification code unique to each product as data and is attached to each product. The wireless tag includes a memory, an antenna, a transmission / reception circuit, and the like, and wirelessly transmits memory data (product identification code) in synchronization with an external electromagnetic wave. The wireless tag reader transmits a wireless electromagnetic wave that is tuned to the wireless tag, inquires about memory data, and acquires memory data by the wireless electromagnetic wave transmitted from the wireless tag. The wireless tag reader is connected to an antenna that transmits and receives wireless electromagnetic waves. The antenna connected to the wireless tag reader is formed in a tunnel shape through which the product container can pass so that the antenna is arranged in all directions of the product container.

  At the checkout place, the store clerk can read the product identification code for one customer from the memory of each wireless tag and input it to the settlement apparatus together with the wireless tag reader without taking out the product from the product container. Therefore, it is possible to shorten the work time for the store clerk to input data to the settlement apparatus, and to reduce the work load on the store clerk (see Patent Document 1).

  On the other hand, if products such as aluminum vapor deposition packages that enclose confectionery or steel cans of juice or alcohol are present near the wireless tag, the antenna of the wireless tag may not function properly, reducing the reception power of the wireless tag. . Accordingly, there is a problem that the wireless tag reader cannot read information of all the wireless tags in the product container.

A high-gain rectifier circuit and a wireless tag using the same are known as a high-sensitivity wireless tag improved so that the wireless tag can operate even when reception power of the wireless tag is reduced (see Patent Document 2).

  In a conventional merchandise settlement system using a radio tag and a radio tag reader, the antenna of the radio tag reader is arranged in all directions of the merchandise container so that the merchandise container can be passed through as a tunnel-like structure at the checkout location. It was necessary to install. When the antenna is configured in a tunnel shape, there is a problem that the facility for the settlement is large. Moreover, the store clerk at the checkout location was required to pass the product container through the tunnel, which was a heavy labor. It is possible to install a belt conveyor in the checkout counter so that the product container is automatically passed through the tunnel, but the facility at the checkout location has to be larger. .

The present invention has been made based on such circumstances, and a product that allows a customer to input product information of a product purchased by a customer using a wireless tag without using a large facility at the checkout location. Provide a payment system. In addition, a portable terminal including a wireless tag reader / writer used in this system is provided.

  In order to solve the above problems, the following configuration is adopted.

  A capacitor, a rectifier circuit, a memory, and an antenna are formed so that an induction current generated by the antenna upon receiving an external radio wave can be charged to the capacitor as a direct current by the rectifier circuit, and provisional settlement information is stored in the memory. In a merchandise settlement system for communicating data related to the merchandise stored in the radio tag in order to perform settlement processing of merchandise having a storable radio tag, the merchandise settlement system includes an antenna provided in a merchandise shelf. The first wireless tag reader / writer is connected to the first wireless tag reader / writer, and the first wireless tag reader / writer puts the provisional settlement information in the memory into an unsettled state via an antenna provided in the product shelf every predetermined time. A product settlement system characterized by

A wireless tag and a barcode formed so that the capacitor can be charged as a direct current by the rectifier circuit with an induction current generated by the antenna by receiving a radio wave from outside; a capacitor, a rectifier circuit, a memory, and an antenna; A portable terminal that communicates data related to a product from a product, wherein the mobile terminal includes a barcode reader and a wireless tag reader / writer, reads barcode information attached to the product, and the wireless tag reader / writer A portable terminal device, wherein provisional settlement information in a memory of the attached wireless tag can be rewritten.

In a transition period in which no wireless tag is attached to all products, the product is settled by using the barcode and the wireless tag together. According to the present invention, a product settlement system using a wireless tag can be constructed even during the transition period. In addition, since the sensitivity of the wireless tag can be controlled, it is possible to avoid a risk that information on the wireless tag can be read by a third party by reducing the sensitivity of the wireless tag after settlement.

  FIG. 8 shows a memory map inside the wireless tag 8. The header indicates the start of data. The product code represents the name of each product. The unique ID is a unique identification number assigned to each product. The settlement flag indicating provisional settlement information indicates whether the product is in a provisional settlement state or an uncleared state. The customer takes out the product 7 from the product shelf 2, reads the barcode 9 of the product with the portable terminal 1 (scanning), rewrites the settlement flag of the wireless tag 8 with the wireless tag reader / writer built in the portable terminal 1, and makes a provisional settlement state. And When the customer returns the product 7 to the product shelf 2, the wireless tag reader / writer 3 of the product shelf 2 rewrites the settlement flag of the wireless tag 8 to an unsettled state. In this way, the settlement information is rewritten into the provisional settlement state and the unsettled state.

  The operation of the wireless tag 8 will be described. When the product 7 is placed on the product shelf 2, the wireless tag reader / writer 3 performs CW transmission (non-modulated wave (Continuous Wave)) and signal transmission from the antenna 5, and is temporarily stored in the memory of the wireless tag 8. Checkout information has been rewritten to an uncleared state. Since the wireless tag 8 is located in the vicinity of the antenna 5, it always exists in a strong electric field radiated from the antenna 5.

  The high frequency power received by the antenna 8a of the wireless tag 8 is converted into a direct current by the rectifier circuit 8c, and the capacitor 8d is charged. The rectifier circuit 8c is applied with a bias voltage by the capacitor 8d, and the rectification sensitivity is increased. When the customer 7 takes out the product 7 to be purchased from the product shelf 2, the wireless tag 8 attached to the product 7 comes out of the strong electric field region radiated from the wireless tag reader / writer 3. Even if the wireless tag 8 leaves the strong electric field region, the rectifier circuit 8c can maintain high sensitivity by the capacitor 8d. Therefore, the wireless tag 8 can maintain the high sensitivity state for several hours.

  A product registration procedure of the product settlement system will be described.

  In the store, when the store clerk displays the product 7 with the wireless tag 8 and the barcode 9 displayed on the product shelf 2, the wireless tag reader / writer 3 performs CW transmission and signal transmission from the antenna 5, so that the wireless tag 8 in the memory The provisional settlement information in is rewritten to an uncleared state. Thereby, when the product 7 is displayed on the product shelf 2 and a predetermined time has passed, the provisional settlement information of all the products is automatically rewritten to an unsettled state. Thereafter, the provisional settlement information of all the products is automatically rewritten to an unsettled state repeatedly every predetermined time.

  The customer places a shopping basket on the cart 6, searches for the product 7 to be purchased while pushing the cart 6, and walks around the store. At that time, the customer walks in the store while holding the mobile terminal 1 and finds the desired product 7, and uses the mobile terminal 1 to put the wireless tag 8 attached to the product 7 into a provisional settlement state. The mobile terminal 1 can be lent to a customer by the store, or the customer can own the mobile terminal 1.

  Although the barcode 9 and the wireless tag 8 are attached to the product 7, it is assumed that the wireless tags 8 are not attached to all the products 7. Therefore, the customer reads the barcode 9 of the product with the barcode reader 1g of the portable terminal 1 when selecting the product and putting it in the shopping basket. At the same time, the wireless tag reader / writer 1h of the portable terminal 1 reads the product code in the memory 8f of the wireless tag 8 attached to the product, rewrites the settlement information of the settlement flag, and enters the provisional settlement state (see FIG. 8). . The product code of the barcode 9 read by the barcode reader 1g and the product code of the wireless tag 8 so that the wireless tag reader / writer 1h will not accidentally rewrite the settlement information of the wireless tag 8 attached to another product. When the two match, the settlement information of the wireless tag 8 is rewritten.

  When only the barcode 9 is attached to the product 7 and the wireless tag 8 is not attached, only the barcode 9 can be read. That is, when the wireless tag reader / writer 1h cannot read the product code of the wireless tag 8, only the barcode 9 is read.

  The controller 1b of the mobile terminal 1 that has recognized the product code of the barcode 9 wirelessly connects to the access point 10 via the antenna 1f by the wireless LAN transceiver 1e, and inquires the server 11 about the product name and price. The product name and price information returned from the server 11 are stored in the controller 1b via the access point 10 and the wireless LAN transceiver 1e, and are displayed on the display 1a. Inquiry of the product name and its product price to the server and obtaining information is called PLU (Price Look Up). The controller 1b stores product information (product code) regarding all products 7 taken out from the product shelf 2 by the customer in a memory provided in the mobile terminal 1. Since the mobile terminal 1 displays the product names, prices, and total price of all the products placed on the cart 6, the customer can know the total price during shopping.

  The customer may stop purchasing the product after the customer reads the barcode 9 of the product 7 with the barcode reader 1g and the wireless tag reader / writer sets the settlement flag to the provisional settlement state. When the customer returns the temporarily settled product 7 to the product shelf 2, the customer reads the barcode 9 of the product 7 with the barcode reader 1 g of the mobile terminal 1 and cancels the returned product information in the mobile terminal 1. When the customer returns the provisionally settled product 7 to the commodity shelf 2, the wireless tag reader / writer 3 performs CW transmission and signal transmission from the antenna 5, so the provisional settlement information in the memory of the wireless tag 8 is not settled. Rewrite to state.

  The procedure for checkout will be described. The customer puts the product provisionally settled with the mobile terminal 1 into the shopping basket, puts it on the cart, and heads for the settlement machine 12. The customer operates the mobile terminal 1 in front of the checkout machine 12 and starts the checkout process. The portable terminal 1 is connected to the access point 10 or the wireless LAN transceiver 12f of the payment machine 12 via the wireless LAN transceiver 1e, and transfers the product information stored in the built-in memory of the portable terminal 1 to the payment machine 12. The checkout machine 12 performs PLU on the transferred product code, obtains the product name and price from the server 11, calculates the total price, and displays the total price on the display 12a.

  The customer puts the money into the money transfer device 12d of the checkout machine 12. Alternatively, payment is made by passing a credit card through the card reader 12k. When the payment is completed, the checkout machine 12 issues a receipt from the receipt printer 12h and transmits the completion of the checkout to the portable terminal 1 via the wireless LAN transceiver 1e. When the portable terminal 1 is lent from the store, the customer returns the portable terminal 1 to the store here.

  Since the customer puts the product 7 on the shopping cart 6 and carries it to the checkout place, and the customer puts cash into the checkout machine 12 or pays with a credit card, the work in the checkout of the store clerk is reduced. Depending on the customer, payment may be made through a store clerk, but even in such a case, work such as carrying goods is reduced.

  The procedure of the shoplifting prevention check is explained. The customer passes through the shoplifting prevention device 13 together with the cart 6 on which the shopping basket is placed. When an inquiry signal is transmitted from the antenna 13f of the shoplifting prevention device 13 to the wireless tag 8 of the product 7, the wireless tag 8 returns only the settlement information. In general, it is considered that the time for the customer to stay in the store, that is, the time from the provisional settlement of the product with the mobile terminal 1 to the settlement with the settlement machine 12 is generally within one hour. Since the capacitor 8d of the wireless tag 8 is designed to last for 1 hour or longer, the wireless tag 8 maintains high sensitivity.

  Therefore, even if the product 7 is randomly stored in the shopping basket or the product 7 such as an aluminum vapor deposition package is mixed and the antenna 8a of the wireless tag 8 is inconsistent, the shoplifting prevention device 13 Can reliably communicate with the wireless tag 8. If the shoplifting prevention device 13 detects a wireless tag whose settlement information is not settled, the alarm device 13c issues an alarm.

  Further, when no wireless tag whose payment information is not yet settled is detected, the shoplifting prevention device 13 transmits a control signal to the wireless tag 8 so that the switch 8g of the wireless tag 8 is turned off. When the control circuit 8e of the wireless tag 8 that has received this signal turns off the switch 8g, the capacitor 8d becomes ineffective and the sensitivity of the rectifier circuit decreases. That is, since the sensitivity of the wireless tag 8 is reduced, the risk of inadvertently reading the information of the wireless tag outside the store is greatly reduced.

  In the configuration of the wireless tag 8 shown in FIG. 7, the control circuit 8e of the wireless tag 8 operates the discharge circuit 8h and the capacitor 8d is discharged by the control signal transmitted from the shoplifting prevention device 13. Therefore, since the sensitivity of the wireless tag 8 is lowered, the risk of inadvertently reading the information of the wireless tag outside the store is greatly reduced.

  The shoplifting prevention device is configured to read only the settlement information of the wireless tag and issue an alarm if there is any unsettled product. By issuing an alarm, the product can be prevented from being stolen. Further, since the sensitivity of the wireless tag is lowered by discharging the capacitor of the wireless tag, it is possible to protect the product information purchased by the customer. The sensitivity of the RFID tag will decrease when the customer leaves the store after the customer has finished shopping, and the privacy of the product purchased by the customer can also be protected. become.

  A commodity settlement method will be described.

  A method for changing the provisional settlement information of the wireless tag 8 to an uncleared state will be described. A merchandise shelf 2 having a plurality of shelf boards is installed in the store. The store clerk displays the product 7 to which the above-described wireless tag 8 and barcode 9 are attached on the shelf board. A plurality of antennas 5 are provided corresponding to each shelf board. A wireless tag reader / writer 3 is provided corresponding to the product shelf 2 and performs CW transmission and signal transmission from the antenna 5. A plurality of antennas 5 are connected to the wireless tag reader / writer 3 via coaxial cables, and each antenna 5 is switched to perform CW transmission and signal transmission. By transmitting CW transmission, that is, sending an unmodulated wave to the wireless tag 8, the capacitor 8d built in the wireless tag 8 is charged. Signal transmission is performed, and provisional settlement information in the memory of the wireless tag 8 is rewritten to an uncleared state. The plurality of antennas 5 provided corresponding to the plurality of shelf boards are sequentially operated, and CW transmission and signal transmission are executed from all the antennas 5. Thereby, when the product 7 is displayed on the product shelf 2 and a predetermined time has passed, the provisional settlement information of all the products is automatically rewritten to an unsettled state. Thereafter, the provisional settlement information of all the products is automatically rewritten to an unsettled state repeatedly every predetermined time. The predetermined time is a time for sequentially driving the plurality of antennas 5 and driving all the antennas 5. Of course, it is also possible to drive sequentially every arbitrary time. Then, after the product settlement is completed, the capacitor provided in the wireless tag is discharged.

  A method of processing by the mobile terminal 1 will be described with reference to a flowchart shown in FIG. When the customer performs an operation of reading the barcode 9 of the product with the barcode reader 1g of the portable terminal 1, the product code (A) is extracted from the barcode 9 as S1. At the same time, the product code (B) based on the wireless tag 8 read by the wireless tag reader / writer 1h provided in the portable terminal 1 is extracted from the data of the wireless tag 8 as S2.

  In S3, it is checked whether only the barcode 9 is attached to the product or both the barcode 9 and the wireless tag 8 are attached. If the wireless tag 8 is not attached to the product (in the case of Y), based on the product code (A) extracted from the barcode 9, information corresponding to the product code is acquired from the server 11 as S7. Thereafter, in S8, the total amount of products processed by the customer on the mobile terminal 1 is calculated, and the amount is displayed on the display unit of the mobile terminal 1. As S9, when the customer does not make the final check-up and the product needs to be read for purchase, it waits for reading the next product. If the payment is to be settled in S9, the portable terminal 1 transfers the total amount to the payment machine 12 by wireless communication when the customer carries the product to the payment machine 12 in S10. When the customer completes payment at the checkout machine 12, the mobile terminal 1 receives a notification of payment completion from the checkout machine 12, and resets the product information and the total amount (S11). After resetting the merchandise information and the total amount of the mobile terminal 1, the mobile terminal 1 is set in an initial state and waits for the next reading.

When both the barcode 9 and the wireless tag 8 are attached at S3, it is checked whether the product code (A) extracted from the barcode 9 and the product code (B) extracted from the wireless tag 8 are equal as S4. . If (A) = (B), the settlement flag in the memory of the wireless tag 8 is changed to the provisional settlement state as S5. Thereafter, the processing after S7 is performed. If both the barcode 9 and the wireless tag 8 are attached but (A) = (B) is not the wireless tag 8 attached to the product taken up by the customer, it is attached to another product near the customer. The wireless tag 8 may be read. Therefore, guidance display is performed on the display unit of the portable terminal 1 (S6). For example, the customer places the mobile terminal 1 in the vicinity of the product and rereads it. Alternatively, the position of the customer is changed so that only the products picked up by the customer are read.

  Payment processing can be completed in a short time for a product including a barcode and a wireless tag using a portable terminal. For the store, the work of transporting goods to the checkout machine is reduced, and the work of the store clerk is reduced. The goods can be prevented from being stolen.

It becomes possible to execute settlement processing for a plurality of products carried in a shopping cart in a supermarket or a shopping center in a short time.
