[0004] In a POS system, by recognizing a product identifier attached to each product, it is possible to obtain information on the product such as the product name and price of the product. For example, it is possible to calculate the total price of purchased products, create a list of purchased products, and the like.

[0005] On the other hand, in recent years, with the progress of the information society, communication terminals capable of transmitting and receiving information via a communication network in the form of personal computers have become widespread even in ordinary households. For example, when trying to manage the inventory of food in a refrigerator at home or the management of purchased products and their payment amounts and payment methods, the communication terminal needs to input information on products purchased by customers. Is inconvenient.

[0006] In the POS system according to the prior art, the digitized information on the merchandise purchased by the customer is P
It is only stored in a storage device inside the OS system and used as internal information of the retailer, and does not have a function of providing computerized information to a customer's home communication terminal or the like.

[0007]

As described above, in the POS system according to the prior art, the information collected during the cashier operation is used only as the internal information of the retailer and is returned to the customer. It does not have a function to provide information to the communication terminal in the customer's home, so if you are trying to manage refrigerator inventory at home or electronically manage household accounts In order to do this, it is necessary to input the information of the purchased article into a home terminal, which is unnecessary.

The present invention has been made in view of the above points, and aims to effectively use information of a POS system.
It is an object of the present invention to provide a system that can eliminate the trouble of inputting information on purchased items at home of a shopping customer.

[0009]

To achieve the above object, the present invention is as follows. That is, the PO of the present invention

A user communication terminal connected to the POS system via a communication network, assigned with unique address information and capable of receiving data addressed by the address information, and the cash register terminal And address information input means for inputting the address information, provided in the POS system, receiving the address information from the address information input means, and purchasing the product information of the terminal user corresponding to the address information, Means for transferring the address to the user communication terminal. And it features.

Further, the POS system includes information holding means for holding description information unique to the product item prepared for the product item, and collects the information of the purchased product together with the description information of the product item. A user communication terminal connected to the POS system via a communication network, assigned with unique address information and capable of receiving data addressed by the address information, and a cash register Address information input means for inputting the address information provided in the terminal; and address information received from the address information input means, provided in the POS system; The process of transferring the description information of the product to the user communication terminal at the address Characterized in that a and.

[0012] In the present invention, the POS system collects information on purchased commodities for each customer handled by the cash register terminal and manages the commodities. Of the collected information, purchases related to the customer of the commodities purchased. The product information is transmitted to the customer's user terminal so that it can be used on the customer's user terminal.

[0013] That is, each item of merchandise is provided with unique item information in advance by, for example, a bar code.
The S system reads by an item information reading means (such as a barcode reader) by a predetermined method,
From the read item information, the price information corresponding to each item information prepared in advance is read, and if there is description information corresponding to the item information, the description information is also read, and the price information corresponding to the item information and the description are read. Obtain information, accumulate the price information, hold the item information, the price information and the description information in a storage device in a predetermined format, and store the stored item information and the price information. The explanation information is transmitted to the user communication terminal specified by the address input by the address information input means via the communication network.

Thus, in the POS system, it is possible to transfer the information on the purchased items created at the time of accounting (at the checkout at the cash register) to the home communication terminal. It is possible to save the trouble of inputting information on the purchased item into the user's own communication terminal.

Further, according to the present invention, a communication terminal that receives item information, price information, and explanation information created by the POS system via a communication network transmits the received item information, price information, and explanation information to each other. The format is such that it is possible to select a perishable food item from the received explanation information, convert the information into a predetermined format, hold the explanation information, and add the explanation information to the food information in the refrigerator.

Thus, in the case where the user communication terminal is a system that can use application software for managing households, such as household account book software, information on shopping on the day is automatically input to the application software. This saves time and effort in data entry, and at the same time, selectively stores information on items stored in the refrigerator from shopping items on the day, and stores information on food added in the refrigerator. The trouble of inputting can be saved.

Still further, in the present invention, the user communication terminal includes an item information reading unit (for example, a bar code reader), and application software of the user communication terminal is read by the item information reading unit. By having a function of deleting an item corresponding to the item information of a shopping product from the food information in the refrigerator, it is possible to save the trouble of deleting information relating to the food taken out from the refrigerator and used. Further, the communication system of the present invention is a system capable of presenting information on foods whose expiration date is approaching to the user communication terminal of the customer by including the expiration date information of the corresponding item in the explanation information.

[0018]

Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 shows a configuration of a communication system according to the present invention. FIG.
, A communication system according to the present invention includes a POS system 102 and communication terminals 103 1,.
Are connected to the communication network 101. The POS system 102 exists, for example, in a supermarket store, and the communication terminals 103 1,..., 103n exist, for example, in customer premises.

FIG. 2 shows a configuration example of the POS system 102. As shown in FIG. 2, the POS system is
01, storage device 202, data input / output terminal (electronic cash register terminal; ECR) 203 1, ..., 203n
Is connected to the intra-POS communication network 204.

Each data input / output terminal 203i (i = 1,
2, 3... N) are POS terminals, each of which is an item information reading device 205 1,.
205n, and address reading devices 206 1,..., 206 n for reading address information for recognizing a customer terminal from, for example, an IC card brought by the customer.

Each data input / output terminal 203i (i =
Although (1, 2, 3,... N) are not shown, a processor, a product key, a setting key, a section key, a subtotal key, a total key, a total key, a numeric key, a cancel key,
A correction key, a change key, a keyboard for operation for inputting various information and commands required as a POS, a display for displaying menu screens and results, a printer for issuing receipts,
It has functional elements necessary for a POS terminal, such as a communication interface, a drawer for storing money, a clock / calendar, and a storage device. The storage device in the data input / output terminal 203i includes a look-up table for giving information on products,
It is used for storing information such as individual information of the products handled in. The look-up table in the storage device in the data input / output terminal 203i has barcode information of the product, product name, manufacturer name, price, product description information,
Information such as the expiration date and the internal capacity is read from the storage device 202 and is referred to at the time of a cash register operation. If the load of the POS system does not become heavy, it is needless to say that the lookup table is not stored in the storage device in the data input / output terminal 203i, and the information is directly extracted by accessing the storage device 202 of the POS system 102. No problem.

The arithmetic unit 20 of the POS system 102
Numeral 1 is a center of arithmetic processing and control required as a POS system, and is a data input / output terminal 203i (i
= 1, 2, 3,... N) to operate as a POS system.

The arithmetic unit 201 and the data input / output terminal 203i are connected to a POS communication network 204 via a built-in communication interface, and an external device is connected via the interface connected to the POS communication network 204. Communication with the communication network 101 can be performed.

The storage device 202 stores the data input / output terminals 20
Information such as product information (unit price, bargain price, product name, manufacturing company, etc.), stock information, and sales point information for each sold individual product to be passed to 3i are stored so as to be searchable and tallyable.

The POS system 102 of the present invention
The customer receives the price information and other information of the product purchased by the customer at the same time from the storage device 202 in the system or from a database outside the POS system and connected to the POS system via a network, and simultaneously purchases the product. Information about the customer, for example, "sex", "age", and "payment method", together with information indicating the item of the sold product, in the POS system storage device 202.
May be configured to be forwarded.

Such information stored in the storage device 202 in the POS system includes information such as “determining the purchase amount of commodities” and what kind of commodities are currently being sold, that is, “what is the best-selling commodities? , What is bad inventory, etc. The item information of a product is generally printed on the packing material of the product in the form of a barcode.

Therefore, in this case, the POS system 102
Is specifically a barcode reader. FIG. 3 shows the POS system 10.
7 is a flowchart of the counting in step 2. The operation of this system will be described with reference to the drawings.

In this system, when a cashier operation for a customer is started, first, an initialization routine is entered (S1).
Then, after the initialization, it is in a state of waiting for input (S
2). In this state, the cashier causes the barcode reader (item information reading device 205i) to read the barcode portion of the purchased product.

Then, the bar code reader detects the bar code of the purchased commodity and sends the read information to the data input / output terminal 203i. When the data input / output terminal 203i detects the item information from the barcode reader, the information is used as a key to provide descriptive information of the product, that is, information indicating "what the product is" or price information. The information is read from a look-up table in a storage device in the data input / output terminal 203i, the explanatory information and the price information are stored, and the cumulative price is calculated (S3, S3).
4, S5).

By the way, for fresh foods such as vegetables, which are not provided with a bar code,
One key on the keyboard of the POS system is assigned to one of those perishables, and information is set so that necessary information can be obtained by operating this key. Will be That is,
One product key on the POS system keyboard,
Assigning the same information as the item information indicated by the bar code, and pressing the assigned key during counting at the cash register, thereby accessing the storage device in the POS system using the item information assigned to the key as a key. It is good. In the communication system according to the present invention, the medium for storing the item information given to each product is not limited to a barcode, and the present invention can be implemented in other formats.

Each time a product purchased by the customer is input to the data input / output terminal 203i by the operation of the cashier, the price and explanation information are read out by referring to the lookup table, stored, and the price is accumulated. Calculation processing and the like are performed, a total is displayed by operating a subtotal key or a total key on the keyboard (S6), and when the information of the buyer is input by operating the cashier's keyboard and payment processing is performed (S7, S8), Next, the data input / output terminal 203i displays an inquiry indicating whether or not a receipt is required by e-mail (S9). The cashier sees this display and inquires of the customer to that effect, and instructs the result to the data input / output terminal 203i by key input.

That is, when unnecessary, when an unnecessary instruction is given, the data input / output terminal 203i prints purchase information on a printer and issues a receipt (S13). Then, the data input / output terminal 203i stores the purchase information in a database in the storage device 202 in the POS system (S12). Then, the processing for one customer is completed.

On the other hand, when receiving the instruction of "Needs receipt by mail", the data input / output terminal 203i waits for the next address input (S10). The address information requested here is the address of the customer terminal. This address information is stored in an IC card or the like in advance by the customer and brought to the cashier, and then handed over to a cashier to have the address reading device 206i read the information or to input the information to the address reading device 206i by himself / herself. For example, the address is input to the data input / output terminal 203i (S10). Upon receiving the address information, the data input / output terminal 203i sends the purchase information of the customer to the intra-POS communication network 204 in, for example, a mail format. Then, the arithmetic unit 201 controls to transmit the information in the mail format to the external communication network 101. As a result, the mail format information is transmitted to the external communication network 101, and the external communication network 101 transmits the mail format information to the communication terminal at the address indicated as the destination of the mail. (S11).

When the information transmission in the mail format is completed,
The data input / output terminal 203i then sends the purchase information to the intra-POS communication network 204 in order to store the purchase information in a database (DB) in the storage device 202 in the POS system.
02 in the database (S1)
2). Then, the processing for one customer is completed. If necessary, the data input / output terminal 203i prints the purchase information on a printer and issues a receipt (S1).
3).

It should be noted that the configuration may be such that the information transfer in the mail format is performed after the storage of the purchase information in the database. As described above, according to the present invention, the detailed information of the purchased product generated in the POS system when the cashier performs payment for the purchased product of the customer is stored in the POS system as information for POS management, By giving the address of the communication terminal owned by the customer, the communication terminal is converted into an e-mail and transmitted to the communication terminal of the address.

That is, all products purchased by the customer are POS
When the information is input in the system 102, the purchase information on all the products purchased by the customer is finally transmitted to the POS system 1.
02 is stored in the storage device 202.

At this time, when the customer notifies the POS system 102 of the address on the communication network 101 assigned to the home communication terminal 103i, the purchase information is converted to an e-mail and sent to the communication terminal of the address. Send it. The method of notifying the POS system 102 of this address is performed, for example, by giving it from a storage medium possessed by the customer. This storage medium uses, for example, an IC card.
The customer may hand the C card to a cashier, and the cashier may insert the IC card into an address reading device 2061 provided in the POS system 102 so that the card can be read. Alternatively, a method may be used in which the customer directly reads the address directly from the address reading device. As a medium for storing the address, in addition to the IC card as described above,
It may be a magnetic card or a portable terminal device such as a PDA. In addition, although the example has been described in which the customer transmits the data of the purchase item list via the communication path, an example in which communication transmission is not used is also conceivable.
For example, it is also possible to adopt a configuration in which any desired method can be selected, such as printing out on paper and handing it out, or inputting it to a small terminal such as a handheld PDA.

The data of the customer address and the list of purchased items may be transferred to a storage device in the POS system or an external storage device. The transferred data of the pair of the customer information and the purchase information is stored in the POS system or an external storage device, and the correspondence between the customer's address, age, gender, occupation, and other parameters and the purchase is shown. This data can be used as an insight, and can be an important reference when knowing customer trends and making individual advertisements to customers. Also, based on this data, it is possible to efficiently perform operations such as collecting defective products.

In this case, it is desirable to store the data for each customer after obtaining the consent of the customer from the viewpoint of privacy protection. For this purpose, the POS
The system includes a pair of the above information (customer address information and purchase information) for the customer (or customer address).
A flag is provided for each customer, indicating whether or not the information about can be stored later.

When the address of the customer's communication terminal is passed through the address reading device, the POS system 102 stores data including item information, price information, and explanation information held in a predetermined format in the storage device. Into an e-mail and send it to the communication address
1, the data may be transmitted in response to a request from the home communication terminal to the POS system. For this information transfer, for example, a connection may be established between the POS system 102 and the communication terminal 103i, and the information transfer may be performed according to a predetermined protocol on the connection.
If the communication network 101 supports mail-based message transfer, these item information, price information and explanation information are converted into a message in the form of a mail to form a message in the communication network 10.
1 and requesting mail transfer to the communication terminal 103i.

In the case of the former method, the POS system 10
2 is directly connected to the communication terminal 103i, so that the communication terminal 1031 needs to have a function of being powered on or of being powered on in response to an incoming call. There is an advantage that information, price information, and explanation information are transferred to the communication terminal 103i.

On the other hand, in the latter case, the communication terminal 10
3i has the advantage of being able to obtain itemized information, price information, and explanation information in a message from the communication network 101 at its own convenience. If the volume is enormous, there is a disadvantage that the message may not yet arrive even if the customer returns to the customer's home. Which method to choose is a matter to be determined by the desired characteristics of the communication system.

FIG. 4 shows an example of commodity price information and explanation information. Contact information for further information in this description information, such as telephone numbers, email addresses,
A description such as a homepage address may be included.

As the communication terminal 103i of the system of the present invention, for example, a personal computer (personal computer) connected to the communication network 101 at home may be used. The communication terminal can display the mail sent from the store, and from the data in the mail,
Household management and food management in a refrigerator may be performed.

As described above, according to the present invention, the item information, the price information, and the description information of the item purchased by the customer are transferred to the communication terminal specified by the address read by the address reading device via the communication network. Information can be transferred to the home communication terminal at the time of purchase accounting, and the customer can return the information about the purchased item to the communication terminal after returning home. The trouble of inputting can be saved.

Now, when returning home from shopping, the customer
The following information processing may be performed using the item information, the price information, and the description information transferred from the S system 102 to the own communication terminal 103i.

The customer's communication terminal may be a personal computer with a so-called modem, and it is assumed that so-called household management software has been installed therein. POS
The data format of the item information, the price information, and the description information transferred from the system 102 is predetermined.

Therefore, it is easy to generate data in a format required by the household management software from the data in this data format. By loading the generated data into the household management software, the customer can purchase on the day. It is possible to save the trouble of inputting the information on the personal computer to the personal computer, and to easily perform the household management by the household management software.

In the present invention, the POS system 1
The description information sent from 02 may clearly indicate that the item corresponding to the description information is to be stored in a refrigerator or a freezer. In this case, the communication terminal 103i holds a list of foods stored in the refrigerator / freezer at home and a list of refrigerated / frozen foods, and the POS system 102 sends item information, description information, and price information. At the stage where the item information and the explanation information are added to the refrigerated / frozen food list in accordance with the information indicating that the item information and the freezer should be stored in the refrigerator or the freezer in the explanation information. ,
Make it clear to the customer by displaying this in the list display.

[0050] This not only saves the customer from inputting the information of the food predicted to be stored in the refrigerator / freezer to his / her own communication terminal, but also necessitates refrigeration / frozen storage. Food information can be automatically and reliably notified. Of course, for the food consumed by the customer, once the refrigerated / frozen food list is displayed and deleted from the list,
It is easier to ensure consistency between the food actually stored in the refrigerator / freezer and the refrigerated / frozen food list. Deleting data is much easier for customers than entering data.

Here, the communication terminal 103i has an item information reading device such as a bar code reader, detects bar code information attached to a product, takes in the information, and uses the bar code information as a basis. In addition to having an application / software configuration capable of managing data deletion, the description information may include a barcode corresponding to the item.

When an item information reading device such as a bar code reader is provided as described above, the bar code printed on the food packaging used after being taken out of the refrigerator / freezer is read. Read at
If the corresponding item of the item information corresponding to the read barcode is deleted from the food information in the refrigerator by causing the communication terminal 103i to capture the read information, the information of the used food can be easily deleted. It is a system that can do it. As a result, it is possible to save the trouble of searching for an appropriate item from the refrigerated / frozen food list, which is necessary when deleting information on the food taken out of the refrigerator and used.

Further, the explanation information may include the expiration date information of the corresponding item. In this case, the expiration date information and the explanation information are used as the expiration date list, and the customer communication terminal 103i (i = 1, 2, 2).
, N), application software is created so as to be stored at a predetermined time.
Alternatively, the expiration date list can be searched according to the customer's request, and the customer can present the food with a near expiration date or the expired food item to the customer as a list. Also, if you do this,
Without inputting the expiration date information, it is possible to use the food stored in the customer's home without waste, and to eliminate the waste of storing the food that has become unnecessary for storage forever.

By the way, there is a possibility that a plurality of foods of the same item are stored in the refrigerator / freezer. In this case, the item read from the refrigerated / frozen food list by the item information reading device is used. The deletion of the item corresponding to the information is more preferably executed in consideration of the expiration date.

That is, when a plurality of foods of the same item are stored, the foods having different expiration dates are presented to the customer as a list, and the customer selects the food corresponding to the expiration date of the food used by the customer. It is a more preferable embodiment to delete the selected food item from the refrigerated / frozen food list.

The information on the list of foods in the refrigerator / freezer held by the customer may be configured so that the store can view the contents by any method. In this case, the store uses the information to purchase the information. The amount can be determined and individual advertisement can be performed efficiently.

As described above, according to the present invention, the POS
In the system, when paying for purchased goods, PO
The detailed information of the purchased product generated in the S system is stored in the POS system as information for POS management, while giving the address of the communication terminal owned by the customer to the communication terminal of that address, It was configured to be transmitted as e-mail. Then, on the customer side, the detailed information of the purchased product received at the home communication terminal is converted into a data format that can be used by application software for managing the household, taken in, and used by the application software for managing the household. By doing so, it is possible to save the trouble of inputting information related to shopping on the day to the application software that manages the household, and to smoothly use the application. At the same time,
The POS system prepares the description information of the product in advance corresponding to each product, and transmits the information from the additional POS system by adding the description information of the product. By inserting information such as / necessity of / freezing, information on items to be stored in the refrigeration / freezer is selectively held from shopping items of the day, and added to the refrigeration / freezer. The management can be performed on the communication terminal side without inputting the information on the food. The present invention is not limited to the specific examples described above, but can be implemented with various modifications.

[0058]

As described above, according to the present invention,
Since the function of transferring the information on the purchased goods collected by the POS system to the customer terminal is provided, the customer can manage the purchased goods without having to input the information by himself / herself.
