Recent mobile phones and PHSs have display screens using liquid crystal, and many of them have a large screen that can display not only characters and symbols but also images. According to the present invention, information relating to a product that a customer has decided to purchase is displayed as a bar code on this liquid crystal display screen, and this bar code is
By reading the information with a barcode reader connected to the OS terminal, information on the traded product can be easily taken into the POS terminal as data.

The method of displaying the bar code on the liquid crystal screen is technically possible as described in several documents, and includes a method of driving the liquid crystal and a surface treatment of the display screen. Use one suitable for reading with a reader.

Although FIG. 1 shows that the mobile phone 21 and the sales site 11 are directly connected, a plurality of server devices and base stations are interposed between them.

Hereinafter, the flow of data and articles in this embodiment will be described with reference to FIG. In the figure, the flow of data is indicated by a solid line, and the flow of goods and money is indicated by a thick white line. Also, codes are given according to the sources of data and articles.

First, the customer 20 uses the mobile phone 21 to access the sales site 11 via the Internet (S201). In response, the sales site 11
Information such as the price and delivery date of the product is transmitted (downloaded) to the mobile phone 21 of the customer 20 as text or image data (S101). This download is performed according to a predetermined protocol such as FTP.

The customer 20 browses the downloaded information on the liquid crystal display screen, selects a product desired to be purchased based on the obtained information, and transmits the order data to the sales site 11 (S202). Upon receiving the order data, the sales site 11 obtains data on the customer 20 such as the TCP / IP address and the telephone number of the accessed mobile phone 21. By storing the data of the customer 20 in association with the mobile phone 21 to be used, individual services can be provided for each customer, such as transmitting specific information or performing a discount.

Then, data for displaying a barcode indicating information on the price and specification of the selected product on the liquid crystal display screen is transmitted from the sales site 11 to the mobile phone 21 (S102).

The data for displaying the bar code can be transferred by any communication method, such as a mobile phone or a P-phone.
It is preferable to use a format that can be displayed on various mobile communication terminals such as HS, for example, an image file format such as GIF, JPEG, or BMP.

Further, the sales site 11 stores order data for each customer, performs a service of discounting the amount according to the total order amount, and transmits barcode data corresponding to the coupon together with barcode data relating to the product. You may do so.

The transaction up to this point is a transaction between the customer 20 and the shop 10 (sales site 11), and is all performed by transmitting and receiving data. The processing on the shop 10 (sales site 11) side is actually performed automatically according to a program stored in the server device 12, and the details of the transaction are stored in a storage device such as a memory in the server device 12.

Next, the customer 20 goes to the convenience store 30 with the mobile phone 21. The mobile phone 21 is read by the bar code reader 32 of the POS terminal 31 of the convenience store.
Read the bar code displayed on. At this time, the customer 20 determines the settlement means and the method of receiving the product (S203).

As a settlement method, there are a cash method, a credit card, a debit from a bank account (account transfer), and a method of paying by adding to a mobile phone usage fee.
0 is appropriately selected and determined. In addition, as a method of receiving the goods, there are a method of receiving the goods at the convenience store 30, home delivery, mailing, and the like, and the customer also appropriately selects and determines these methods.

The convenience store 30 issues a slip or a receipt based on the information read from the bar code displayed on the liquid crystal display screen of the mobile phone 21 and the determined settlement and delivery method (S301). It is desirable that the slip and the receipt also indicate the expected arrival date of the product. In the illustrated example, it is assumed that settlement by debit from a bank account and receipt at a convenience store are selected.

Here, for example, when payment by cash is selected, the customer 20 pays the amount corresponding to the price on the spot, and the convenience store 30 issues a receipt indicating that the payment has been received. If the bank account is debited, the convenience store 30 issues a slip describing the settlement method,
At a later date, the amount corresponding to the price is withdrawn from the bank account designated by the customer 20 to the management center of the convenience store 30 or the like.

The convenience store 30 transmits the information read from the barcode and information such as the determined settlement method to the shop 10 via the Internet as order data (S302). As a result of the above processing, all the data necessary for the commercial transaction such as the seller, the purchaser, the product, the price, the settlement method, and the product delivery method are completed.

After receiving the order data from the convenience store 30, the shop 10 ships the merchandise (S103).
Here, an example of sending to the convenience store 30 is shown, but the customer 20 will send to the place where he / she wants to receive.

The convenience store 30 stores the merchandise dispatched from the shop 10, and in this case, when the customer 20 comes to the store, passes the merchandise in exchange for the issued slip (S303).
Then, as described above, the amount corresponding to the price is withdrawn from the bank account designated by the customer 20 to the management center of the convenience store 30 at a later date (S204). The convenience store 30 remits an amount obtained by subtracting a predetermined fee to the shop 10 (S
304). As described above, all the processes related to the commercial transaction are completed.

The illustrated example shows a case where the settlement by debit from the bank account and the receipt at the convenience store are selected as described above, and the case where another settlement method or the receipt method is selected. Although the contents and the order of the processing after the commodity is sent out (S103) will be different, these processings are not new and are not specifically described here.

As described above in detail, the present embodiment has the following effects.

By transmitting the barcode data as image data, regardless of the communication method or the web browser,
Electronic commerce can be performed using any mobile communication terminal using the current environment.

Since the bar code is read and the information on the product is converted into data again, by describing the sales site in another foreign language, even foreigners who are not able to speak Japanese can conduct business transactions. The same applies to deaf and dumb people.

Through the convenience store, a settlement method and a commodity delivery method can be selected according to the needs of the customer.

Various services can be provided by the sales side storing customer transaction information in association with the mobile phone.

[Modification of First Embodiment] A modification of the first embodiment will be described below. The description of the same parts as those in the first embodiment is omitted.

In the first embodiment, the information on the product that the customer has decided to purchase is displayed as a bar code on the liquid crystal display screen of the mobile phone, and the bar code is read by a bar code reader connected to the POS terminal. Was a thing,
In this modification, a barcode downloaded from a sales site is printed on a recording medium such as paper by a printer connected to a mobile phone, and the barcode printed on paper is read by a barcode reader 32 of a convenience store. It is.

That is, in addition to the configuration shown in FIG. 1, when the customer 11 has a printer connectable to his / her own mobile phone 21, the barcode downloaded from the sales site 11 is recorded on paper using this printer. I do. Then, bring the paper on which the barcode is printed to the convenience store 30, and
It is characterized by being read by a barcode reader 32 connected to the OS terminal.

The flow of data and articles in this modification will be described with reference to FIG.
After the transmission of the barcode data to “0” (S102), a step in which the customer 20 prints the barcode with a printer is added. Thereafter, instead of bringing the mobile phone 21, the customer 20 brings the paper with the barcode
Going to 0, the barcode is read and the settlement means and the method of receiving the commodity are determined (S203). Subsequent processing is the same as in the first embodiment, and a description thereof will be omitted.

In recent years, the size of a liquid crystal display screen of a portable telephone has increased and the resolution has also increased. In addition, the number of types capable of color display is increasing, and the types of information displayed on the screen are also increasing. For this reason, there has been an increasing demand for printing and saving the information of the displayed screen on paper or the like.
Lightweight mobile printers are also available.

As a printer for printing a bar code,
It is not particularly necessary to be small and lightweight as long as the display screen of the mobile phone can be printed, but a mobile printer that can be carried with the mobile phone is more preferable.

On the other hand, as in the first embodiment, in order to directly read the bar code displayed on the liquid crystal display screen of the mobile phone with the bar code reader connected to the POS terminal,
The size and specifications (contrast, reflectance, etc.) of the screen are restricted according to the specifications of the barcode reader. For this reason, some mobile phones currently in use cannot read the barcode displayed on the screen.

The present modification is also applicable to a customer who uses a mobile phone of a model that cannot directly read a bar code displayed on a screen with a bar code reader.
C provides convenience.

Even if a mobile phone of a model that can directly read the bar code displayed on the screen with a bar code reader is used, when purchasing a plurality of products at the same time or using several electronic coupons, Since it is necessary to repeat the display and reading of the barcode at the convenience store a plurality of times, it is more convenient for the customer to print the required plurality of barcodes on paper and bring them once.

[Second Embodiment] Hereinafter, a second embodiment of an electronic commerce system using a mobile communication terminal according to the present invention will be described. The description of the same parts as those in the first embodiment is omitted.

In addition to the configuration of the first embodiment shown in FIG.
Has a barcode reader 22 connected to the mobile phone 21. Instead of the customer 20 accessing the sales site of the shop 10 and exchanging information, the shop 10 issues a catalog 40 on which a barcode 41 is printed, and the customer 20
Reads the barcode 41 of the product desired to be purchased with his / her own barcode reader 22 by looking at the catalog 40 and stores the information in the mobile phone 21. Then, the customer 20 places an order with the sales site 11 of the shop 10, and at this time, the customer 20 also determines a settlement means and a method of receiving the product. The sales site 11 that receives these data returns the confirmation data to the mobile phone 21 in the form of a barcode when the data necessary for the commercial transaction is available.

That is, in the first embodiment, the shop 10 exchanges information with the customer 20 via the sales site 11, but in the present embodiment, the shop 10 advertises via the catalog 40 and the customer 20 The user selects a product from the catalog 40, reads the corresponding barcode, and places an order using the data.

Hereinafter, the flow of data and articles in this embodiment will be described with reference to FIG. In FIG. 4, similarly to FIG. 2, the flow of data is indicated by solid lines, and the flow of articles and money is indicated by thick white lines.

First, the shop 10 issues a catalog 40 which prints bar codes indicating information on prices and specifications corresponding to the products to be sold and each product (S40).
1). The catalog 40 may be a pamphlet or a flyer, or may be an advertisement published in a newspaper or a magazine.

Next, the customer 20 refers to the catalog 40, selects a product to be purchased, and causes the corresponding bar code 41 to be read by the bar code reader 22 connected to the mobile phone 21 (S402). Then, an order is placed by transmitting the read information of the barcode 41 to the sales site 11. At this time, the customer 20 determines a settlement means and a method of receiving the product (S403).

The settlement means and the method of receiving the goods are the same as those of the first embodiment.
This is the same as the embodiment. In the illustrated example, it is assumed that settlement by debit from a bank account and receipt at a convenience store are selected.

The shop 10 uses the bar code information transmitted from the customer's mobile phone and the determined settlement method and the like to carry out business transactions such as seller, purchaser, merchandise, price, settlement method, and commodity delivery method. When it is confirmed that all the data is complete, the barcode data for confirmation is returned from the sales site 11 to the customer's mobile phone 21 (S40).
4). In the present embodiment, the commercial transaction has been established at this point, and the actual delivery of the product and settlement of the price are performed thereafter.

The customer 20 having received the data of the confirmation bar code goes to a convenience store 30 which desires to receive the goods,
The bar code reader 32 connected to the POS terminal 31 of the convenience store reads the confirmation bar code.

The convenience store 30 issues a slip or a receipt based on the information read from the confirmation bar code displayed on the liquid crystal display screen of the mobile phone 21 (S30).
1). It is desirable that the slip and the receipt also indicate the expected arrival date of the product.

At an appropriate time after receiving the order from the customer, the shop 10 sends out the merchandise (S103). Here, an example of sending to the convenience store 30 is shown, but the customer 20 will send to the place where he / she wants to receive.

Since the subsequent processing is the same as that of the first embodiment, detailed description is omitted here.
The delivery of the goods at 0 (S303), the withdrawal of the price (S204), and the remittance to the shop 10 (S304) are performed, and all the processing ends.

The illustrated example shows the case where the settlement by debit from the bank account and the receipt at the convenience store are selected as described above, and the case where another settlement method or the receipt method is selected. , The contents and order of the processes will be different, but these processes are not new and are not particularly described here.

According to this embodiment, the following effects are obtained in addition to the effects of the first embodiment.

Since the customer refers to the printed catalog when selecting a product, more information can be obtained at a time than through the display screen of the mobile phone, and a more satisfactory product selection can be performed.

Since the customer does not need to access the Internet when selecting a product, the customer does not spend much time and money.

Further, since catalogs printed on various mobile phones can be provided, it is possible to sell many products at once.

[Modification of Second Embodiment] As a modification of the second embodiment, a confirmation barcode downloaded from a sales site is transmitted to a mobile phone in the same manner as the modification of the first embodiment. A printer connected to a printer and printed on a recording medium such as paper, and the barcode printed on the paper is read by a barcode reader 32 at a convenience store is of course conceivable.

In the second embodiment, the catalog 4
The bar code 41 printed on the “0” is read by the bar code reader 22 connected to the mobile phone 21 and the information is transmitted to the shop for ordering.
