PURPOSE: A system for providing the market price of raw material and product information by using user location information is provided to offer product information of each raw material based on a user location, thereby enabling a user to use the product information without individually searching a product on sale at the user location or a product fit for the user location. CONSTITUTION: A user terminal(100) derives a global positioning coordinate and a user location coordinate. A main server(300) collects the market price of raw material or raw material processed product information in real time. The main server provides the market price of raw material or the raw material processed product information depending on the positioning reliability of the user terminal. An information telecommunication network(200) connects the user terminal to the main server. |
