CONSTITUTION: A stock information transmission server computer(100) collects stock information from a stock market and transmits collected stock information to a wireless call network(130). A stock inquiry-transaction terminal(200) receives stock information from the wireless call network(130) to display received stock information, and outputs transaction order information. A bidirectional communication terminal equipment is connected with the stock inquiry-transaction terminal(200) for transmitting transaction order information, and is connected to a socket communication network. A stock transaction computer(150) is connected to a bidirectional communication network, and transmits stock transaction order information to the stock market. A user inquires stock information transmitted to the stock inquiry-transaction terminal(200) through the wireless call network(130) in the stock inquiry-transaction terminal(200). The user generates stock transaction order information and transmits generated stock transaction order information through the stock inquiry-transaction terminal(200) and the bidirectional communication terminal equipment for performing the inquiry of stock information and the stock transaction. |
