Here, the case where the buyer is an intermediary such as an agency and is different from the final consumer of the product is illustrated. If the buyer is the final consumer, a personal page in a form excluding the final consumer name from the illustrated page is displayed.

The buyer confirms the contents of the final quotation on this web page, and clicks the order button “Go to cart” on the right end of the screen to place an order with this content. Note that a cart is a shopping cart, and clicking this symbolizes placing a product on the shopping cart and means ordering the product. Thus, the electronic order of procedure 516 is performed. CGI is also used for electronic ordering.

The web page has a structure in which the contents cannot be changed by the viewer except for the input unit by the CGI. Therefore, the buyer cannot make any changes to the content of the final quote presented on the web page.

In step 518, the seller receives an electronic order as described above. Orders are received by CGI script. The content of the final quotation shown on the personal page is guaranteed to be the same (authentic) as the one presented by the seller, so it is not necessary to match the order content with the final quotation when placing an order. There is no problem at all. Thereby, the order receiving work can be performed smoothly.

Thereafter, the seller delivers the ordered product to the buyer, and charges for the price. The buyer receives the goods and pays for them. This ends the transaction. A program for causing a computer to realize the functions of each terminal as described above is recorded on a recording medium so as to be readable by the computer. As the recording medium, for example, a magnetic recording medium, an optical recording medium, a magneto-optical recording medium, and other appropriate recording media are used. The recording medium may be a semiconductor storage medium. In this document, a storage medium is synonymous with a recording medium.

In the above, the description has been given of an example in which the commodity to be dealt with is a medical device. However, the commodity is not limited to the medical device, and may be any commodity that can be traded in the market. Also, the form of the product is not limited to goods,
Information, services, financial products, etc. may be in any form.

[0067]
