Description

  The present invention relates to a product sales data processing device that reads a product code from a wireless tag attached to a product and processes product sales data based on the read product code.

  In recent years, a wireless tag is attached to a product, data related to the product to which the wireless tag is attached is stored in the memory of the wireless tag, product management is performed using the data stored in the wireless tag, and sales of the product are performed. Various techniques for processing data have been proposed.

  For example, when a response of a product code for identifying a product to which the wireless tag is attached is received from a wireless tag, product sales data is processed based on the product code, and data of the wireless tag attached to the product is processed. There was a merchandise sales data processing device to be rewritten (see, for example, Patent Document 1).

In addition, the wireless tag memory stores freshness data such as the expiration date and date of manufacture of the product to which the wireless tag is attached, and the product data is read from the freshness data read from the wireless tag and the date and time in the system. There has been a merchandise management system that determines discount or privilege data, and displays and prints this discount or privilege data (see, for example, Patent Document 2).

  However, in these conventional techniques, the wireless tag is delivered to the customer in a state where it is attached to the product after the stored data is left as it is or rewritten with new data. Even after being delivered to the customer, it is possible to read data stored in the memory of the wireless tag by using the wireless tag reader. For this reason, the following problems may occur.

  For example, the wireless tag can store various data such as a store code, a sales price, and a sales date in addition to the product code. Many customers are not aware that a wireless tag is attached to a product brought home, and are considered to be left as it is. For this reason, if you walk around the customer's home with a wireless tag reader, you will know what products are in the home, and when, at what store, and how much the products are purchased. Become. In addition, by providing a wireless tag reader at the store entrance and exit, it is possible to determine when and at what store the clothing, bags, ornaments, etc. that the customer who visited the store has purchased. It becomes like this.

  Such a thing is convenient for the product manufacturer and the product seller because it can grasp the consumption trend of the customer. However, it is a serious problem from the viewpoint of personal privacy protection and personal data protection.

  On the other hand, it may be more convenient for the customer to keep the wireless tag attached. For example, by using a refrigerator with a wireless tag reader, automatic recognition of products stored in the refrigerator, automatic management of the expiration date, and the like can be performed. In addition, by reading the RFID tag data attached to the purchased product with a wireless tag reader connected to a personal computer at home, data such as the sales price and date of the purchased product can be easily stored in the household account book software on the personal computer. Can be entered.

  Therefore, when a wireless tag is attached to a product for sale, the problem is that the customer knows that the wireless tag is attached to the product and what data is stored in the wireless tag. Without purchasing the product without knowing that the wireless tag is attached, and carrying or using the purchased product.

  The present invention has been made based on such circumstances, and the object of the present invention is that a wireless tag is attached to a product and what data is stored in the wireless tag. An object is to provide a product sales data processing apparatus capable of notifying a customer and preventing personal data of the customer from leaking from a wireless tag attached to a product purchased without the customer's knowledge. Is.

  The merchandise sales data processing apparatus of the present invention includes a radio tag data reading means for reading a merchandise code stored in a radio tag attached to a merchandise, and merchandise sales data for processing merchandise sales data based on the inputted merchandise code.

The tag type code is a code for identifying the type of the wireless tag 8. The wireless tag 8 is managed as a different type every time items of tagged product related data are different. The items of the tagged product related data include a product code of a product to which the wireless tag 8 is attached, a sales price, a sales date, a store code of the store, and the like. In addition, items such as the size and color of clothing items are added to wireless tags attached to clothing items, and items such as expiration date and date of manufacture are added to wireless tags attached to food items. Sometimes.

  FIG. 5 is an external perspective view of the POS terminal 2, the wireless tag reader / writer 5 and the barcode scanner 6 connected to the POS terminal 5, and FIG. 6 is a block diagram showing the main part thereof. The POS terminal 2 is provided with a keyboard 21 and a display 22 as an operator display on the front, and a display 23 as a customer display on the back. A receipt printer 24 for printing a receipt is built in, and a receipt printed by the receipt printer 24 is discharged from a receipt issuing port 24A. Furthermore, the drawer 25 for accommodating cash etc. is provided.

  The operator display 22, the customer display 23, and the receipt printer 24 function as product data output means for outputting product sales data such as the name, price, and total price of the product processed by the product sales data. The keyboard 21 is provided with a closing key that functions as a registration closing means for instructing the end of the merchandise sales data processing for one customer.

  The POS terminal 2 provided with such input / output devices includes a CPU (Central Processing Unit) 26 constituting a main control unit, a ROM (Read Only Memory) 27 and a RAM (Random Access Memory) 28 constituting a main storage unit, Data of an HDD (Hard Disk Drive) device 29 that is a nonvolatile auxiliary storage device, a clock unit 30 that measures the current date and time, a LAN interface 31 that controls data communication performed via the LAN 3, and data of the wireless tag reader / writer 5 A wireless tag reader / writer interface 32 for controlling communication and a scanner interface 33 for controlling data communication with the barcode scanner 6 are mounted. Also, a keyboard controller 34 for controlling the keyboard 21, a display controller 35 for controlling the operator display 22, a display controller 36 for controlling the customer display 23, a printer controller 37 for controlling the receipt printer 24, and an opening command signal for the drawer 25 are provided. An output I / O port 38 and the like are provided.

  The wireless tag reader / writer 5 includes an interface unit 51 that exchanges data signals with the POS terminal 2, a modulation unit 52 that modulates transmission radio waves to the wireless tag 8, and a transmission amplifier 54 that amplifies the modulated waves and radiates them from the antenna 53. A receiving amplifier 55 that amplifies the radio wave received by the antenna 53, a demodulator 56 that demodulates the amplified radio wave, a radio wave to the radio tag 8 in response to a command from the POS terminal 2, or from the radio tag 8 The control unit 57 is configured to analyze data included in the received radio wave and transmit the data to the POS terminal 2. The antenna 53 is embedded in the wireless tag reader / writer 5 on which a plurality of products can be placed at the same time, and the communication distance above the wireless tag reader / writer 5 is a communication area with the wireless tag 8. The wireless tag reader / writer 5 can simultaneously read the wireless tag data (ID, tag type code, tagged product related data) stored in the wireless tag 8 attached to a plurality of products by the anti-collision function. Here, the wireless tag reader / writer 5 constitutes wireless tag data reading means.

  A tag format table 41 having a data structure shown in FIG. 7 is stored in the HDD device 29 of the POS terminal 2. In the tag format table 41, a tag type code and the number of items of tagged product related data stored in the user area 871 of the wireless tag 8 identified by the type code are set. A series of item numbers, data sizes, item names, and statuses are set for each item of tagged product related data. The status is “0” when the corresponding item is an item stored in advance, and “1” when the item is written at the time of sales data processing of the product to which the wireless tag 8 is attached. The tag format table 41 shown in FIG. 7 has four items of “product code”, “store code”, “sales price”, and “sales date” as items of tagged product related data, and only “product code” is stored in advance. This corresponds to the stored type of wireless tag 8. Such a tag format table 41 exists for each type of wireless tag.

  In the RAM 28 of the POS terminal 2, a product registration memory 42 having an area configuration shown in FIG. 8 is formed. In the product registration memory 42, an area in which a product code input via the wireless tag reader / writer 5 or the barcode scanner 6 is written and a product name and price of the product identified by the product code are written for each serial number. Area that is turned on when the product code input source is the wireless tag reader / writer 5, and the area of the input source determination flag F that is turned off when other than that, and the wireless tag read by the wireless tag reader / writer 5 An area where 8 data (ID, tag type code, tagged product related data) is written is secured.

  FIG. 9 to FIG. 10 are flowcharts showing the main procedure of merchandise sales transaction processing with one customer executed by the CPU 26 of the POS terminal 2. That is, the CPU 26 clears the product registration memory 42 and initializes the write counter W to “0” (ST1), and then waits for the product code of the product purchased by the customer to be input (ST2).

  During the standby period, the wireless tag reader / writer 5 transmits a wireless tag reading radio wave from the antenna 53. In this state, when the wireless tag 8 exists in the communication area of the antenna 53, the wireless tag data stored in the memory 87 of the wireless tag 8 is read and sent to the POS terminal 2. When a plurality of wireless tags 8 are present in the communication area, the wireless tag data is read in order and sent to the POS terminal 2. The bar code scanner 6 scans the laser beam light. In this state, when the laser beam light scans the barcode, black and white barcode data is optically read and sent to the POS terminal 2.

  Therefore, when the RFID tag data read by the RFID tag reader / writer 5 is input via the RFID tag reader / writer interface 32, the CPU 26 divides the RFID tag data into an ID, a tag type code, and a product related code with tag. . Then, the tag format table 41 is searched with the tag type code, and the position (item number) and data size of the item “product code” included in the tagged product related data are acquired. A product code is extracted by analyzing the tagged product related data stored in the attached product related data area. When the barcode data read by the barcode scanner 6 is input via the scanner interface 33, the barcode data is analyzed to extract a product code.

  When the product code is thus extracted, the CPU 26 determines that the product code has been input. Then, it is determined whether the product code is a product code extracted from the wireless tag data or a product code extracted from the barcode data (ST3: input source determination means). This determination can be made, for example, by adding an identification code to the product code extracted from the wireless tag data.

  If the input product code is a product code extracted from the wireless tag data, the CPU 26 increments the write counter W by “1” (ST4), and then inquires the store server 1 with this product code. The product data set corresponding to the product code is called from the product master file 4. Then, the product code and the product name and price in the product data are stored in the Wth (W is the value of the write counter W) of the product registration memory 42 (ST5). Also, the Wth input source determination flag F is turned on (ST6).

  Next, the CPU 26 registers product sales data in the RAM 28 based on the product data called from the product master file 4 (product sales data processing means), and stores the product name and price on the operator display 22 and customer display 23. It is displayed on the registration screen (ST7: merchandise sales data output means).

  Next, the CPU 26 acquires data corresponding to the item whose status is “1” in the tag format table 41 and instructs the wireless tag reader / writer 5 to write to the wireless tag 8 (ST8). For example, when the product tag input source wireless tag 8 is of a type corresponding to the tag format table 41 of the data content shown in FIG. 7, store code, sales price, and sales date data are acquired. The store code is set in the RAM 28 in advance. The sales price is called from the product master file 4. The sales date is counted by the clock unit 30. Each data is given to the wireless tag reader / writer 5 together with a write command. In the wireless tag reader / writer 5, each data is modulated, and the modulated amplified wave is transmitted from the antenna 53. At this time, the wireless tag reader / writer 5 has established a line with the wireless tag that has read the wireless tag data. Therefore, the modulated amplified wave is received by the antenna 81 of the wireless tag 8 in which the line is established. Each data (in this case, store code, sales price, sales date) is written in the user area 871 of the memory 87 in the wireless tag 8.

  Next, the CPU 26 reads the wireless tag data (ID, tag type code, tagged product-related data) read from the wireless tag 8 and the data of the item whose status is “1” written to the wireless tag 8. Stored in the Wth item of the product registration memory 42 (ST9). Further, a wireless tag attention message, a wireless tag mark, and wireless tag data, which will be described later, are displayed on the customer display 23 as data indicating that the wireless tag is attached to the product (ST10: output control means).

  In the merchandise sales transaction process with this one customer, the CPU 26 executes each process of ST4 to ST10 each time a merchandise code extracted from the wireless tag data is input.

  On the other hand, if the input product code is a product code extracted from the barcode data in the determination process of ST3, the CPU 26 counts up the write counter W by “1” (ST11), and then An inquiry is made to the store server 1 with the product code, and the product data set corresponding to the product code is called from the product master file 4. Then, the product code and the product name and price in the product data are stored in the Wth of the product registration memory 42 (ST12). Further, the Wth input source determination flag F is turned off (ST13). Thereafter, the CPU 26 registers product sales data in the RAM 28 based on the product data called from the product master file 4 (product sales data processing means), and stores product names and prices on the operator display 22 and the customer display 23. It is displayed on the registration screen (ST14: merchandise sales data output means).

  In the merchandise sales transaction process with this one customer, the CPU 26 repeatedly executes the processes of ST11 to ST14 each time a merchandise code extracted from the barcode data is input.

  Thereafter, when a closing key is input (ST15), the CPU 26 performs a registered product closing process for processing the sales of the registered product based on data such as a product code, a product name, and a price stored in the product registration memory 42. Execute (ST16). When the registered merchandise closing process ends, the CPU 26 initializes the read counter R to “0” (ST17). Next, the read counter R is incremented by “1” (ST18), and it is determined whether or not the write counter W has been exceeded (ST19).

  If the read counter R does not exceed the write counter W, the CPU 26 acquires R-th data (R is the value of the read counter R) from the product registration memory 42 (ST20). Based on this data, receipt print data is created (ST21). Further, it is determined whether or not this data input source determination flag F is on (ON) (ST22). If it is on (ON), a wireless tag is attached to the receipt print data. As data indicating that the wireless tag is received, a wireless tag attention message, a wireless tag mark, and wireless tag data described later are added (ST23).

  Thereafter, the read counter R is further incremented by “1”. Then, until the read counter R exceeds the write counter W, the CPU 26 repeatedly executes each process of ST20 to ST23.

  When the read counter R exceeds the write counter W, the CPU 26 controls the drive of the receipt printer 24 to print receipt print data on receipt paper and issue a receipt (ST24: output control means). If the opening command signal for the drawer 25 is output from the I / O port 38 (ST25), the CPU 26 ends the merchandise sales transaction process with one customer.

  In the store where the system of the present embodiment configured as described above is introduced, two products “jacket A” “slack B” each having a wireless tag 8 of a type corresponding to the tag format table 41 shown in FIG. ”And a product sales transaction with a customer who purchases one item“ sock C ”with no wireless tag 8 attached, the store clerk will purchase the product“ jacket A ”,“ slack B ”,“ sock ” C ”is placed on the wireless tag reader / writer 5.

  Then, since the wireless tag 8 is attached to the product “jacket A”, the wireless tag data stored in the memory 87 of the wireless tag 8 is read by the wireless tag reader / writer 5 and given to the POS terminal 2. As a result, the product code of the product “jacket A” included in the product related data with the tag of the wireless tag data is input to the POS terminal 2, and the product name of the product “jacket A” is stored in the product master file 4 based on the product code. And the price (suppose 30,000 yen) is called. The product code, product name, and price of this product “jacket A” are stored in the first area of the product registration memory 42, and the input source determination flag F is turned on. In addition, the store code, the sales price, and the sales date are written in the user area 871 in the memory 87 of the wireless tag 8 attached to the product “jacket A” via the wireless tag reader / writer 5, and the store code and the sales price. The sales date data is stored in the first area of the product registration memory 42 together with the ID, tag type code, and product code of the wireless tag 8 attached to the product “Jacket A”.

  Next, since the wireless tag 8 is also attached to the product “Slacks B”, the wireless tag data stored in the memory 87 of the wireless tag 8 is read by the wireless tag reader / writer 5 and given to the POS terminal 2. . As a result, the product code of the product “Slacks B” included in the tagged product related data of the wireless tag data is input to the POS terminal 2, and the product name of the product “Slacks B” is stored in the product master file 4 based on this product code. And the price (10,000 yen) is called. Then, in the second area of the product registration memory 42, the product code, product name and price of this product “Slacks B” are stored, and the input source determination flag F is turned on. In addition, the store code, the sales price, and the sales date are written in the user area 871 in the memory 87 of the wireless tag 8 attached to the product “Slacks B” via the wireless tag reader / writer 5. The sales date data is stored in the second area of the product registration memory 42 together with the ID, tag type code, and product code of the wireless tag 8 attached to the product “Slax B”.

  Further, the product name and price of the product “Jacket A” and the product “Slacks B” are displayed on the operator display 22 and the customer display 23. At the same time, the customer's display 23 displays a preset RFID tag warning message and RFID tag mark, and RFID tag data stored in the registered product memory 42.

  The store clerk does not display the data of the product “sock C” on the operator display 22 among the 3 products placed on the wireless tag reader / writer 5, so that the product “sock C” does not have the wireless tag 8 attached thereto. Can be recognized. Therefore, the store clerk scans the barcode of the price tag label 7 attached to the product “sock C” with the barcode scanner 6. When it is known that the wireless tag 8 is not attached to the “sock C”, it is not necessary to first place the “sock C” on the wireless tag reader / writer 8.

  When the barcode of the price tag label 7 is scanned by the barcode scanner 6, the product code of the product “sock C” is input to the POS terminal 2, and the product “sock C” is stored in the product master file 4 based on the product code. The product name and price (thousand yen) are called. Then, the product code, product name and price of the product “sock C” are stored in the third area of the product registration memory 42, and the input source determination flag F is turned off. Further, the product name and price of the product “sock C” are displayed on the operator display 22 and the customer display 23.
