The present invention relates to an e-commerce
system and method using a networked retail store, comprising: a buyer terminal that accesses a retail store shopping mall of a data
broadcasting service, searches for a product, selects and orders it, and enters a
payment number to receive the ordered product; a retail store headquarters
server having a product DB regarding various products that can be searched; a data
broadcasting server that provides a product search and order screen to the buyer terminal by linking the product DB of the retail store headquarters
server in real time when a retail store shopping mall menu is selected on a broadcast screen after the buyer terminal is connected via a set-top box by the buyer; a retail store terminal that is connected to the retail store headquarters server via a
dedicated line and is networked on a regional basis; a transaction confirmation /
authentication system that receives the buyer's
payment number from the data
broadcasting server, verifies it, and transmits the authenticated result to the data broadcasting server; and a financial institution server that receives financial information such as the buyer's
payment number from the transaction confirmation /
authentication system, processes the payment approval when a payment request
signal is transmitted from the data broadcasting server, and transmits the payment result to the data broadcasting server. According to the present invention, since each retail store (mart, supermarket, discount store, convenience store, etc.) networked with a
dedicated line in each region of the country can be utilized, rapid delivery is possible 24 hours a day, year-round, and returns and exchanges can be made quickly in the event of product defects.
