[0006]

Some problems have been proposed for such a POS system for the purpose of further improving the service. One of them is to provide a wide variety of information that is useful at stores and the like via the POS system,
The aim is to create an environment where customers can shop more comfortably and satisfyingly. In the conventional POS system, only the minimum necessary contents such as a product name, a price, and a total billed amount are displayed on the customer display, and the display that matches the needs of the user is not always performed. Absent. If a large-sized display is adopted as the customer display instead of the conventional display having about 2 characters and 20 characters, it is possible to display various value-added information on the customer display. However, if the display processing of those contents is performed on the POS terminal, it becomes a heavy load on the POS terminal, and the operation speed of the POS terminal device is reduced, or a high-performance and expensive machine for the POS terminal needs to be introduced. There is.

[0007] The display contents and display screens of the customer display change according to the progress of the display contents, the type of store, the request of the store owner, and the like. To cope with this, it is necessary to remodel the application software of the POS terminal. is there. For this reason, it is difficult to display an image adapted to each store or the needs of each occasion.

Next, there is a security problem. For example, in the current POS system, the operator and the customer face each other with the POS terminal in between, and the operator cannot be protected against violent acts by the customer. If the distance between the operator and the customer is large, it is not easy to answer the customer's inquiry or return the purchased product. Also, handling of credit cards and IC cards becomes difficult, and service to customers is reduced.

There is also a problem of privacy protection (protection of personal information). When a password is required to use a credit card, point card, etc.,
In the current POS system, there are many opportunities for an operator to contact the personal information of these customers. For this reason, the security of personal information such as passwords is affected by uncertain requirements such as the reliability of the operator.

As described above, the current POS system is considered to have some improvements, and an object of the present invention is to provide a POS system that can solve these problems.

[0011]

According to the present invention, there is provided a POS system in which a POS terminal is divided into an operator terminal (operator terminal) and a customer terminal (customer terminal 9). Then, the customer terminal device of the present invention is transmitted from an operator terminal device capable of inputting sales data.
It is characterized by having a data acquisition unit capable of acquiring transaction data including at least product name information and quantity information, and a data display unit capable of creating display data based on the transaction data and outputting the data to a display. In addition, the control method of the customer terminal device of the present invention includes a data acquisition step of acquiring transaction data including at least product name information and quantity information transmitted from an operator terminal device capable of inputting sales data, based on the transaction data. And a data display step of creating display data and outputting it to a display.

According to the present invention, a system independent of the operator terminal device is provided by installing an independent customer terminal device so that display data can be created from transaction data left as a sales record from the operator terminal device. Can function as a customer display. Therefore, since the display method and the screen configuration can be handled on the customer terminal device side, various contents can be displayed on the display without changing the application software of the operator terminal device. Since the operator terminal device only needs to transmit the transaction data, the system can be made highly versatile without being affected by the display software on the customer terminal device side. In addition, since the load does not increase even if the display content increases, the POS system can be built with a low-cost machine. Therefore, by providing such a customer terminal device, it is possible to provide a POS system that can provide information that matches the needs of the customer and that is useful for constructing an environment in which shopping can be performed more comfortably. Also, since various information can be provided by the customer terminal device, unlike a conventional POS system in which sales are performed through a customer to a cash register, the customer can be guided to a service counter or the like to provide a variety of useful information, and sales processing can be performed. , It is possible to construct a new store system that performs such a process.

Although it is possible to directly connect the customer terminal device to the operator terminal device, the customer terminal device is connected via a computer network, and the transaction data output from the operator terminal device via the computer network is transferred to the data acquisition unit. It is desirable to be able to obtain at. On the other hand, in the control method of the customer terminal device, it is desirable to acquire the transaction data via the computer network in the data acquiring step. By mutually connecting via the computer network in this way, the customer terminal device can be arranged at a desired place irrespective of the installation position of the operator terminal device. In a conventional POS system, a customer display is attached to a POS terminal, so that the customer and the operator are opposed to each other. By making the devices independent, the distance between the customer terminal device and the operator terminal device can be easily separated, and the degree of freedom in arranging the customer terminal device and the operator terminal device increases. Can be. Also, conversely,
It is also effective in protecting customer personal information.

When the customer terminal device is connected to the computer network in this manner, POS data such as a product name, a unit price, and bargain information relating to transaction data is obtained from a data acquisition unit or a server connected to the computer network in the data acquisition process. Then, it becomes possible to convert the transaction data and the POS data into display data in the data display section or the data display step, and display the data on the display. In this way, the load on the operator terminal can be further reduced, and the content that more closely matches the needs of the customer can be displayed on the display. For example, when a potato is today's special sale item, it is possible to obtain normal potato price information from the server and simultaneously display both the today's selling price and the normal selling price on a display. You can know the price reduction rate and its discount rate.

When the customer terminal device is connected to a computer network, not only POS data related to the transaction data but also value-added information such as store layout information from the server in the data acquisition unit or data acquisition process. Information about recommended products, time service information, and the like are acquired, and the information can be displayed on a display. Therefore, the customer can obtain more useful information from the customer terminal device, and can make shopping more comfortable and satisfying. It can also be used as a display means for soliciting advertisements for point cards and the like, and has a high advantage on the store side. Although only the value-added information may be displayed on the display, it goes without saying that the value-added information may be displayed together with the transaction data. Such information can be displayed by using browser software. By connecting to the Internet, the customer terminal device can be provided with a wide range of functions.

In the customer terminal device or the control method therefor, a data input unit or a data input step capable of inputting customer data including personal information of a customer, and a customer data input through the data input unit or the data input step are transmitted. If a data transmission unit or a data transmission step capable of transmitting data to the operator terminal device is provided, personal cards such as credit cards and smart cards can be handled. By doing so, for example, the birthday or the like can be known from the credit card owned by the individual.
It is possible to acquire message information and present information of "day" and to display the contents on a display, so that customers can shop more comfortably.

When the customer terminal device of the present invention and the operator terminal device are connected via a computer network, data may be directly exchanged between the operator terminal device and the customer terminal device. It is of course also possible to exchange data via the Internet.

In the customer terminal device or the control method thereof, an operation section or an operation process is provided in which the customer can operate the display state of the display to select a display screen, scroll the screen, and sort the purchased products (sorting). ) Is desirably prepared. As a result, the customer can operate the display and freely display the content that he or she wants to check, so that the service can be improved. Furthermore, even if the customer terminal device is set apart from the operator terminal device, the customer can operate it, so that the service can be prevented from lowering. It is further desirable to provide a data printing unit or a data printing process capable of creating print data so that the screen selected by the customer can be printed. Furthermore, when a receipt is not desired, it is desirable to provide an operation unit or an operation process capable of canceling the receipt issuance, to avoid unnecessary receipt issuance, and prevent waste of resources such as paper and ink. .

As an operator terminal device for transmitting and receiving data to and from the customer terminal device of the present invention, display related processing can be performed on the customer terminal device side.
A data input unit capable of inputting sales data, a data generation unit capable of generating transaction data including at least product name information and quantity information from the sales data, and a customer device capable of converting the transaction data into display data and displaying the display data on a display An apparatus having a data transmission unit capable of transmitting the transaction data created by the data creation unit to the destination can be used. Further, as a control method of the operator terminal device, a data input step of inputting sales data, a data generating step capable of generating transaction data including at least product name information and quantity information from the sales data, and a display data And a data transmission step of transmitting the transaction data created in the data creation step to a customer terminal device that can be converted to the data and displayed on the display. Therefore, the operator terminal device and its control,
In particular, since the display-related configuration or control can be simplified,
The load can be reduced, the processing speed can be improved, and the cost of the operator terminal device can be reduced.

As a result, the display 51, the touch panel 52, the card reader 53, and the peripheral devices of the receipt printer 54 connected to the main body 50 can be used, and the customer terminal 3 is connected to the computer network 4. . Then, control of screen display on the display 51 is executed in step ST4.

The customer terminal 3 enters the ready state, and in step ST5, a process of receiving data sent from the operator terminal 2 and the store server 5 to the customer terminal via the computer network 4 is performed. Next, if the data received in step ST6 is transaction data φ2 from the operator terminal 2,
In step ST12, a process of converting the transaction data φ2 into display data is performed. On the other hand, if the received data is data (server data) transmitted from the store server 5, a process of displaying the data is performed in step ST13. The server data includes POS data for following the contents displayed on the conventional customer display including the product name and price, and added value such as discount information and store layout which could not be displayed on the conventional customer display. And extensive value-added data. Of the server data, the POS data is mainly used for displaying purchase details when a customer checks in. The value-added data is provided to the customer together with the purchase details or independently. Examples of value-added data include today's special sale information, special sale information of this week and this month, time service, solicitation advertisement of point card issued by store, introduction of recommended products, layout information in store, product information, etc. is there. These display contents may be switched periodically, or a plurality of pieces of information may be simultaneously displayed on the display screen. It is also possible to display a Web page provided by the store on the Internet, or to display the contents of the various information described above on this Web page. In any case, the contents displayed on the display 51 and the layout of the image are controlled by the application software 70 of the main body 50.
And browser software can be used for display.

When predetermined contents are displayed on the screen of the display 51 in step ST13, data can be input from the touch panel 52 or the card reader 53 in step ST8. If there is an input in step ST9, step ST
At 14, processing according to that can be performed. Accordingly, the customer terminal 3 of the present example can select and display information stored in a server connected to the computer network 4 or information on the Internet. Then, the advertisement of the store can be displayed on the display 51 for the customer, and the bargain information, the sales point of the store, and the like can be more clearly shown to the customer.

If the touch panel 52 has an input section for selecting the in-store layout information, the customer can touch the input section to forcibly change the display contents of the display 51 to the in-store layout information. Can be. In addition to such a screen selection, if an input unit is prepared for causing the touch panel 52 to print a display screen, the display contents of the display 51 can be printed out. In order to print the display screen in this way, a LAN printer or the like may be connected to the computer network 4, and
A printer may be directly connected to the main body 50. Further, the receipt printer 54 can be used if the size is large.

Further, when the customer's point card is read by the card reader 53 in step ST9, it recognizes that the customer data has been input from the card reader 53 in step ST14, and proceeds to steps ST10 and ST11. The customer data can also be transmitted to the store server 5. Then, in step ST7, information related to the information of the point card, for example, the number of usable points of the point card is obtained from the store server 5, and the content is displayed in step ST13. As described above, in the customer terminal 3 of this example, the display content of the display 51 is changed by operating the touch panel 52 or the card reader 53 provided on the display 51 at times other than check-in, to meet customer needs. Information can be provided. In this way, the customer can know at a glance where the target product counter is located, and the shopping can be performed more comfortably and satisfactorily.

On the other hand, at the time of check-in, a display as shown in FIG. When the customer checks in, on the operator terminal 2 side, transaction data φ2 including at least product name information and quantity information is created based on the sales data φ1 input by the operator using the barcode scanner 13, and this transaction data φ2 is The information is transmitted to both the store server 5 and the customer terminal 3 via the computer network 4 as information. The customer terminal 3 acquires the transaction data φ2 from the operator terminal 2 in step ST6, and
2 and the display data φ6 are created based on the server data (POS data), and the display data φ6 is displayed in the area A in step ST12. As shown in FIG. 7, in the customer terminal 3 of this example, a product name and its unit price are obtained as POS information based on the product name code and the quantity of the transaction data, and these are combined to become display data. In region A, beer, wine, potato

The input unit provided on the touch panel 52 is not limited to the above example, and an input unit for printing a display screen or an input unit for inputting a personal identification number may of course be provided. As described above, of the control of the customer terminal 3, an operation for giving convenience to the customer is open to the customer. Therefore, even if the operator terminal 2 and the customer terminal 3 are installed in separate places separated from each other, it is possible to prevent a decrease in service.

The contents displayed on the display 51 shown in FIG. 7 are merely examples, and the present invention is not limited to this example. For example, a product may be displayed on the display 51, and when the customer selects the displayed product on the touch panel, the product may be additionally purchased. As a product to be displayed on the display 51, a product under a campaign, particularly a bargain product, or a large and heavy product unsuitable for carrying by a customer may be displayed. In this case, if the product displayed on the display 51 is small, the product may be placed on the operator side, and when the product is selected, the operator may hand the product directly to the customer. If the product is large and heavy, it may be delivered at a later date. Also,
Items to be displayed on the display 51 include items, accessories, and consumables related to the item purchased by the customer, such as matches and candles when incense is purchased, a filter pack for a vacuum cleaner, and a flashlight for a flashlight. Will display batteries and other foods to supplement tea and calcium if you buy a lot of sweet foods, and if you have a customer's past shopping history, analyze the customer's preferences from that history Then, a product suitable for the taste may be displayed.

As described above, in the POS system 1 of this embodiment, the independent customer terminal 3 is installed, and the customer terminal 3 converts the transaction data φ2 to the display data φ6, which are recorded as a sales record from the operator terminal 2. That can be created. Therefore, since the display method and the screen configuration can be processed on the customer terminal 3 side, various contents can be displayed on the display 51 without changing the application software of the operator terminal 2.
Can be displayed. On the other hand, the operator terminal 2 only needs to transmit the transaction data φ2. In other words, a highly versatile system can be provided without being affected by the display software of the customer terminal 3. Further, even if the content displayed on the display 51 increases, the load on the operator terminal 2 does not increase, so that a POS system can be constructed with a low-cost machine. Therefore, by providing the customer terminal 3 of the present example, it is possible to provide a new POS system that can provide information that matches the needs of the customer and can construct an environment where shopping can be performed more comfortably.

In addition, since the customer terminal 2 can be arranged at a desired place irrespective of the installation position of the operator terminal 2, the conventional POS system has a customer display attached to the POS terminal. Although it is an opposing system and is almost defenseless with respect to security such as theft, the distance between the customer terminal 3 and the operator terminal 2 can be easily separated, and a POS system superior in security can be realized.

[0053]

As described above, in the present invention, a customer terminal device independent of the operator terminal device is provided, display data is created from transaction data from the operator terminal device by the customer terminal device, and a display method is provided. The screen configuration and the like can be processed on the customer terminal device side. Therefore, various contents can be displayed on the display without changing the application software of the operator terminal device. On the other hand, since only the transaction data needs to be transmitted as the operator terminal device, a highly versatile system that is not affected by display software on the customer terminal device side can be adopted. Further, even if the content displayed on the display increases, the load on the operator terminal device does not increase, so that the POS system can be constructed with a low-cost machine. This makes it possible to provide a new POS system that can provide information that matches the needs of the customer and can construct an environment that makes shopping more comfortable. Since the degree of freedom in arranging the customer terminal device and the operator terminal device increases, a POS system superior in security can be realized.
