Detailed Description of the Invention

[0001]

The present invention relates is related to merchandise sales data registration processing apparatus having a data rewrite capabilities of the non-contact communication storage medium.

[0002]

2. Description of the Related Art First, sales registration and return registration of customer-purchased merchandise at a store such as a convenience store will be described. Generally, in such a store, each product is provided with a bar code representing product code data for identifying the product. Further, a scanner for reading the bar code is connected to a control unit of a commodity sales data registration processing device called a POS (point of sale information management) terminal or an electronic cash register. The product sales data registration processing device can select at least a sales registration mode and a returned goods registration mode, and usually the sales registration mode is selected.

When a customer in charge of accounting receives a request for accounting for a purchased product from a customer, the salesclerk reads the bar code attached to the purchased product one by one with a scanner. By doing so, this bar code data is taken into the control unit of the product sales data registration processing device via the scanner, the product code of the customer purchase product is recognized from the bar code data, and the customer purchase is performed based on this product code. The sales data of the product is registered for sales in the storage unit. Then, when the registration of all the products purchased by one customer is completed, the total amount of all the products purchased by this customer is displayed on the display unit of the product sales data registration processing device, and the clerk asks the customer for payment. Then, when payment is received from the customer, the payment data is input from the keyboard of the product sales data registration processing device. As a result, the printing section of the merchandise sales data registration processing device issues a receipt on which the detailed data of all the merchandise purchased by the customer is printed, so that the clerk delivers the receipt to the customer. This completes the sales registration work for one customer.

When the customer in charge of accounting receives a request to return the merchandise from the customer, the clerk in charge of accounting requests the receipt of the purchase of the returned merchandise. Then, if it is confirmed from the contents of the receipt that the returned product is the product purchased at our shop, after switching the mode of the product sales data registration processing device to the returned product registration mode, the bar code attached to the returned product Read with a scanner. By doing this, this bar code data is taken into the control section of the merchandise sales data registration processing device through the scanner, the merchandise code of the returned merchandise is recognized from the bar code data, and the merchandise of the returned merchandise is recognized based on this merchandise code. The sales data is returned to the storage unit for registration processing. Further, since the refund amount is displayed on the display unit of the merchandise sales data registration processing device, the clerk refunds the refund amount to the customer. This completes the return registration business for one customer.

By the way, in stores such as convenience stores, surveillance cameras are arranged in various places in the store, and mirrors are installed at the sales floors that are blind spots from the sales staff in charge of accounting to prevent shoplifting. Such a shoplifting prevention system was unreliable. Therefore, recently, introduction of a shoplifting prevention system using a wireless tag, which has already been put into practical use in video rental stores and the like, is being considered. This shoplifting prevention system attaches to each product a non-contact communication type storage medium that emits radio waves when it resonates at a specific frequency, a so-called wireless tag, and a transmitter that transmits the specific frequency to the entrance and exit of the store, and a radio. A receiver for receiving radio waves from the tag is provided. When the receiver receives the radio wave from the wireless tag, it is judged as shoplifting, and an alarm is issued from the alarm device. When such a shoplifting prevention system is introduced, for example, a sales clerk in charge of accounting removes the wireless tag of the product whose sales data has been sales-registered in the product sales data registration processing device or destroys the communication function of the wireless tag.
By doing this, the alarm will not be issued even if the customer leaves the shop with the registered product, but if you try to leave the shop with the unregistered product, the wireless tag attached to the unregistered product Since a radio wave is emitted from to issue an alarm, shoplifting can be reliably prevented.

[0006]

One of the problems to be solved by the present invention is the merchandise return business. That is, conventionally, it has been confirmed from the contents of the receipt whether or not the returned product is the product purchased at our shop. For this reason, when the customer requests the return of the same product purchased at another store, the data of the returned product is recorded in the receipt, so that the product can be returned. Therefore, despite the lack of assurance that the returned merchandise itself was sold at this store, the store was forced to accept the returned merchandise. In addition, there is a problem that the customer cannot return the goods if the receipt is lost.

[0007]

The present invention has been made under such circumstances, and the purpose thereof is to automatically invalidate the return of goods sold at other stores without burdening the clerk in charge of accounting. The present invention intends to provide a commodity sales data registration processing device capable of performing the above.

[0009]

The invention according to claim 1 of the present application is capable of selecting at least a sales registration mode and a returned goods registration mode. When the sales registration mode is selected, the sales data of each product registered by the product registration means is displayed. In the product sales data registration processing device that performs sales registration processing in the storage unit and returns the sales data of each product registered by the product registration means to the storage unit when the return registration mode is selected, each product is provided with a store of a store. A non-contact communication type storage medium for storing code data and status data for identifying unregistered or registered is stored, and stored in the non-contact communication type storage medium provided for the product registered by the product registration means. The reader / writer unit that reads the data and writes the data to the contactless communication type storage medium is controlled by the product sales data registration processing device. When the store code data and the status data stored in the non-contact communication type storage medium provided in the registered product is read through the reader / writer unit, the control unit connects the store code data to the store of the own store. Checks whether the code matches and whether the status data is unregistered or registered, and when the sales registration mode is selected, if the store code of the own store and the status data are not registered, sales registration processing of sales data of the registered product And rewrite the status data of the non-contact communication type storage medium provided in the registered product through the reader / writer unit to registered,
When the return item registration mode is selected, if the store code of the store is already registered and the status data has already been registered, the return item registration process for the sales data of the registered item is performed and the contactless communication type provided for the registered item through the reader / writer unit. The status data of the storage medium is rewritten to be unregistered.

The invention according to claim 2 of the present application is the above claim 1.
In the invention according to claim 1, the non-contact communication type storage medium stores the merchandise code data for identifying the merchandise provided with the medium, and the merchandise sales data registration processing device reads the non-contact communication type storage medium via the reader / writer unit.

Has become. The alarm device 9 determines from the data of the wireless tag 2 whether shoplifting has occurred,
When shoplifting occurs, an alarm buzzer 10 provided near the checkout place is activated.

In this embodiment, however, each product 1
The SRAM 26 of the wireless tag 2 attached to each of the
The single item data table T having the data structure shown in FIG. Here, the tag ID code d1 is code data for identifying the wireless tag 2, and the store code d2 is
The product code d3 is code data that identifies a store that sells the product to which the wireless tag 2 is attached, and the product code d3 is code data that identifies the product to which the wireless tag 2 is attached.
The registration status d4 indicates that the product to which the wireless tag 2 is attached is unregistered by data “00”, and the registered status is indicated by data “11”.

In such a structure, when the RFID tag reader / writer 5 is brought close to the RFID tag 2 attached to the product 1,
The data stored in the SRAM 26 of the wireless tag 2 is read by the wireless tag reader / writer 5, and the read data is input to the reader / writer interface 416 of the POS terminal 4. Then, the CPU 401 of the POS terminal 4 is controlled by the program so as to start the processing shown in the flowchart of FIG.

That is, when the CPU 401 starts this process, first, the data d1 to d4 of the single-piece data table T are stored in the RAM from the data of the wireless tag 2 input to the reader / writer interface 416 as ST (step) 1.
Take in 403. Next, the business mode selected by the mode switch 406 is checked. Here, when the sales registration mode is selected (YES in ST2),
Since this is the sales registration business for the product 1, the store code d2 is checked from the data d1 to d4 of the single item data table T fetched in the RAM 403, and it is determined whether or not it matches the own store code (our store code) set in the RAM 403 in advance. To do. Then, if they match, then the registration status d4 is checked to determine whether or not the data is "00" indicating unregistered. Then, in the case of the data "00" indicating unregistered, the product data such as the product name and unit price corresponding to the product code d3 is called from the product data file, and the sales amount = unit price,
Acquire product sales data with the number of sales = 1. Then, this product sales data is subjected to sales registration processing in the storage unit of the RAM 403. At this time, the display unit 410 displays the product name, sales amount, and the like. Further, the printer 411 prints receipts and journals of detailed data such as product name, unit price, number of sales, and sales amount. A product data file in which product data such as a product name and a unit price is preset corresponding to a product code of each product is provided in the RAM 403 or a storage device of a line-connected store computer.

Thereafter, the CPU 401 causes the RAM 4
Data d1 to d of the single-piece data table T taken in 03
The registration status d4 out of 4 is data “0
0 "is updated to data" 11 "indicating that the data has been registered. Then, the data d1 to d1 of the updated single-piece data table T are updated.
When d4 is transmitted to the wireless tag reader / writer 5 through the reader / writer interface 416, the processing of this time is ended. If the result of checking the store code d2 is not the same as our store code, and if the result of checking the registration status d4 is data “11” indicating that the product has been registered, the sales registration operation of this product 1 is made an error. To end.

On the other hand, as a result of checking the business mode selected by the mode switch 406, if the return merchandise registration mode is selected (YES in ST3), it is the merchandise 1 return merchandise registration business, so that it is taken into the RAM 403. Store code d2 of data d1 to d4 of single item data table T
Is checked and it is determined whether or not it matches the code of the own store (our store code) set in the RAM 403 in advance. If they match, then the registration status d4 is checked to determine whether or not the data is "11" indicating that the registration has been completed. Then, in the case of the data “11” indicating that the product has been registered, the product data such as the product name and unit price corresponding to the product code d3 is called from the product data file, and the sales amount = unit price, sales point =
Acquire product sales data of item 1. Then, the product sales data is returned to the storage unit of the RAM 403 and registered.

Thereafter, the CPU 401 causes the RAM 4
Data d1 to d of the single-piece data table T taken in 03
Data "1" indicating that the registration status d4 out of 4 has been registered
1 "is updated to data" 00 "indicating unregistered. Then, the data d1 to 1 of the updated single-piece data table T is updated.
When d4 is transmitted to the wireless tag reader / writer 5 through the reader / writer interface 416, the processing of this time is ended. If the result of checking the store code d2 is not the same as our store code, and if the result of checking the registration status d4 is data "00" indicating unregistered, the return registration operation of this product 1 is made an error. To end.

In this way, the data d1 to d of the updated single-piece data table T transmitted to the RFID tag reader / writer 5 are transmitted.
4 is transmitted from the wireless communication unit 54 to the wireless tag 2 attached to the product 1 and is overwritten on the single item data table T formed in the SRAM 26 of the wireless tag 2.

On the other hand, as shown in FIG. 7, the alarm device 9 waits for reading the data of the wireless tag 2 attached to the product passing between the transmitter 7 and the receiver 8. When the data of the wireless tag 2 is read by the data from the receiver 8, the data d1 to d4 of the single item data table T are fetched from the data of the wireless tag 2. Then, the store code d2 in the data d1 to d4 is checked to determine whether it matches the store code. If they do not match, the data of the wireless tags other than the wireless tag 2 attached to the product sold at the store is read, and the process returns to the data reading standby state of the wireless tag 2.

On the other hand, if the store code d2 matches the store code, then the registration status d4 is checked,
It is determined whether or not the data is data "00" indicating unregistered.
Here, in the case of the data “11” indicating that registration has been completed, the PO
Since the data of the wireless tag attached to the product 1 for which sales registration processing has been performed is read at the S terminal 4, the wireless tag 2 returns to the data read standby state.

On the other hand, when the registration status d4 is the data "00" indicating that the product is not registered, the product 1 which is sold at the store but is not registered for sales at the POS terminal 4 Since the data of the wireless tag attached to the tag has been read, it is determined that shoplifting has occurred, and the alarm buzzer 10 is sounded for a certain period of time. After that, the wireless tag 2 returns to the data reading standby state.

In the store of the present embodiment configured as described above, when the accounting clerk 3 receives a request for accounting for a purchased product from a customer, the RFID tag 2 attached to the customer-purchased product 1 RFID tag reader / writer 5 for each item of data
Read with. By doing so, the data d1 to d4 of the single-piece data table T stored in the SRAM 26 of the wireless tag 2 are transferred to the P tag via the wireless tag reader / writer 5.
It is taken in by the CPU 401 of the OS terminal 4. Then, when it is confirmed that the store code d3 of the single item data table T matches the store code and the registration status d4 is data "00" indicating unregistered, the product code d3 of the single item data table T is confirmed. Based on the above, the sales data of the customer-purchased product 1 is sales-registered in the storage unit of the RAM 403. Further, the registration status d4 of the data d1 to d4 of the single item data table T stored in the SRAM 26 of the RFID tag 2 attached to the customer purchase product 1 is rewritten from unregistered “00” to registered “11”. . It should be noted that the store code d2 in the single-item data table T is not the store code, and the product with the wireless tag 2 and the registration status d
The sales registration of the product 1 to which the wireless tag 2 having the data “11” indicating that 4 is registered is an error.

Thus, when the sales registration of all the products purchased by one customer is completed, the total price of all the products purchased by this customer is displayed on the display unit 410 of the POS terminal 4.
The clerk asks the customer for payment. When the customer receives payment, the payment data is input from the keyboard 409 of the POS terminal 4. As a result, the printer 411 of the POS terminal 4 issues a receipt on which the detailed data of all the products purchased by the customer are printed, so that the clerk delivers the receipt to the customer. This completes the sales registration work for one customer.

After that, the customer exits the store exit 6 with the product 1 for which sales registration has been completed. At this time, the registration status d4 of the single item data table T stored in the SRAM 26 of the wireless tag 2 attached to the product 1 for which sales registration has been completed is registered “11”, so the alarm device 9 does not operate.

However, when the customer tries to exit from the store exit 6 with the product 1 whose sales registration has not been completed, the registration status d4 of the single item data table T stored in the SRAM 26 of the RFID tag 2 attached to this product 1 Is not registered "00", the alarm device 9 is activated and the alarm buzzer 10
Sounds to notify the clerk 3 that shoplifting has occurred.

On the other hand, when the customer in charge of accounting receives the request to return the merchandise 1 from the customer, after switching the mode switch 406 of the POS terminal 4 to the merchandise return registration mode, the RFID tag 2 attached to the merchandise return 1 is returned. The data is read by the RFID tag reader / writer 5. By doing this,
The data d1 to d4 of the single item data table T stored in the SRAM 26 of the wireless tag 2 are taken into the CPU 401 of the POS terminal 4 via the wireless tag reader / writer 5. Then, when it is confirmed that the store code d3 of the single item data table T matches the store code and the registration status d4 is the data "11" indicating that the product has been registered, the product code d3 of the single item data table T is confirmed. Based on the above, the sales data of the customer-purchased product 1 is returned to the storage section of the RAM 403 and registered. Further, the registration status d4 of the data d1 to d4 of the single item data table T stored in the SRAM 26 of the wireless tag 2 attached to the returned product 1 is rewritten from registered “11” to unregistered “00”. Further, since the refund amount is displayed on the display 410 of the POS terminal 4, the clerk refunds the refund amount to the customer. This completes the return registration business for one customer. It should be noted that registration of a returned item for the product 1 with the wireless tag 2 whose store code d2 in the single item data table T is not the store code causes an error.
Similarly, the registration status d4 indicates that the data is "0".
Returning goods registration of the product 1 with the RFID tag 2 of 0 "also causes an error.

As described above, according to the present embodiment, for each product 1, the store code data d2 of the store, the product code data d3 for identifying the product, and the status for identifying whether the product is unregistered or registered. A wireless tag 2 that stores data d4 is provided. Further, the reader / writer 5 of the wireless tag 2 is connected to the POS terminal 4.

Then, the CPU 401 of the POS terminal 4
Indicates whether or not the store code data d2 and the status data d4 stored in the wireless tag 2 provided in the registered product 1 are fetched via the wireless tag reader / writer 5 and the store code data matches the store code of the own store. And whether the status data is unregistered or registered.

Here, when the sales registration mode is selected by the mode switch 406, the sales data of the registered merchandise 1 is registered on the basis of the merchandise code data d3 when the shop code of the own shop is not registered and the status data is not registered. Performs sales registration processing and wireless tag reader / writer 5
The status data d4 of the RFID tag 2 provided on the registered product 1 is rewritten to the registered item via the.

Further, when the return item registration mode is selected, when the store code of the own store and the status data are already registered, the return item registration process of the sales data of the registered item is performed based on the item code data d3. Through the wireless tag reader / writer 5, the status data d4 of the wireless tag 2 provided in the registered product 1 is rewritten as unregistered.

Therefore, when the customer requests the return of the product purchased at another store, the store code d2 stored in the RFID tag 2 attached to the product does not match the store code of the own store. The registration becomes invalid. In addition, even if the customer takes an unregistered product that is sold at his / her shop to the checkout place and makes a fraudulent request to return the product, the registration status d4 stored in the wireless tag 2 attached to the product is Since the data "00" indicates that the product has not been registered, the merchandise return registration is invalid.

[0038] As a result, the store side can carry out the return operation even if there is no receipt, and it is possible to eliminate the loss on the store side due to the unreasonable return because it is possible to confirm that the returned product itself is the one sold in our shop. it can. Also, if the customer loses the receipt, it can be returned as long as it is a legitimate product,
The serviceability for customers is also improved. In addition, the registration status d of the wireless tag 2 attached to the product 1 that has been returned and registered.
The data No. 4 is automatically rewritten from the registered data "11" to the unregistered data "00", so that the returned merchandise can be sold again in the shop.

Further, according to the present embodiment, the exit 6 of the store
An alarm device 9 for shoplifting prevention is installed in the shop. The alarm device 9 reads the status data d4 stored in the wireless card 2 attached to the product 1 passing between the transmitter 7 and the receiver 8 provided at the exit 6, and the status data d4 is read.
Is registered or not registered, and if the status data is "00" which is not registered, the alarm buzzer 10 is sounded to issue an alarm. As for the status data d4, the data of the RFID tag 2 attached to the product 1 that has undergone the sales registration processing at the POS terminal 4 is automatically rewritten from the unregistered data “00” to the registered data “11”. Therefore, the shop assistant 3 in charge of accounting can prevent shoplifting with high reliability without performing a special operation for preventing shoplifting, so that the burden on the shop assistant and the processing efficiency of the registration work can be improved.

Further, the alarm device 9 stores the status data d4 and the store code d2 stored in the wireless card 2 attached to the product 1 passing between the transmitter 7 and the receiver 8 provided at the exit 6. Read the unregistered status data “0
When the number is 0 "and the store code d2 matches the store code, the alarm buzzer 10 is sounded to issue an alarm. For example, the RFID tag 2 is attached to a product sold in another store. However, that store may not have the function of rewriting the registration status d4 of the wireless tag 2 at the time of sales registration.In such a case, if the customer comes to the store to purchase the product purchased at another store, When passing through the exit 6, the status data d4 will pass with an unregistered product, but since the store codes do not match at this time, an alarm is not issued and the customer does not feel uncomfortable.

The present invention is not limited to the above-mentioned one embodiment. For example, in the above-described embodiment, the product code data d3 is stored in the wireless tag 2 and the product code data d3 is read by the wireless tag reader / writer 5 to register the product. May be attached to the product as a barcode, and the product may be registered by reading the barcode with a barcode scanner. However, in this case, the bar code scanner is provided with a wireless tag reader / writer function, and the wireless tag 2 is attached near the bar code so that the reading and rewriting of the wireless tag data can be performed simultaneously with the reading of the bar code. Need to

Further, in the above-mentioned embodiment, the system including the transmitter 7, the transmitter 8 and the alarm device 9 is provided at the exit 6 of the store, but it may be provided at a passage through which shoplifting customers can pass.
Needless to say, the warning means is not limited to the buzzer. Of course, various modifications can be made without departing from the scope of the present invention.

[0043]

As described in detail above, according to the present invention,
It is possible to provide a merchandise sales data registration processing device that can automatically invalidate returns of merchandise sold at other stores without burdening the sales clerk in charge of accounting even without a receipt .
