The present invention relates to an electronic-commerce assisting method capable of smoothly and securely conducting electronic commerce on a communication network, and to an electronic-commerce assisting server for realizing the same. The present invention is configured to have a communication terminal () for a person desiring to purchase a product, who connects to a cybershop () on a communication network () and who desires the purchase of a product using a credit card; an electronic-commerce server (), disposed in the cybershop (), for determining whether or not the electronic commerce should be concluded on the basis of the credit confirmation of the credit card; and an electronic-commerce assisting server () which requests the communication terminal () to transmit unique number data within the IC card () having a credit card function via the communication network (), which converts the received unique number data into a credit card number in order to generate credit limit data of the credit card, and which transmits credit OK/NG data to the electronic-commerce server ().

Electronic commercial transaction support method

A method for purchasing an item using a terminal apparatus connected to a supplier server through a communication line. The method includes accumulating data associated with a user request to purchase an item at the supplier server. The supplier server contacts a credit company server to obtain a credit contract associated with the user request. The credit company server may then send a credit contract to the user, if the user is authorized to receive credit. Another aspect provides a method for electronic purchase of a good. This method includes selecting a credit payment method for the good being purchased using a user terminal coupled to a server. The server then determines payment options associated with the credit payment method.

Electronic goods-purchasing method and commercial-transaction apparatus therefor

In a semiconductor device of the type comprising a semiconductor substrate made of P type silicon, a P type monocrystalline silicon region formed on the major surface of the substrate and containing a P type impurity, and a porous silicon oxide region surrounding the P type silicon region, the porous silicon oxide region is made to contact all side surfaces of the P type silicon region and all or at least a portion of the bottom surface thereof.

Semiconductor devices and method of manufacturing the same

A signalling system for multi-address calling and a signal control equipment therefor in which a control signal starts with a synchronize signal, followed by a function determination field indicating that the control signal is any one of a selection signal, a call accepting state indication signal and a data receiving state indication signal, the function determination field being followed by a terminal appointing field in which the signal, set in the function determination field is provided bit by bit in a predetermined order for each destination terminal. Circuit arrangements for transmitting and receiving such a control signal are provided as signal control equipments both on the side of an originating terminal and on the side of an exchange.
