PURPOSE: The method for intermediating the cash back service using the wire/wireless Internet is provided for a client to buy goods with inexpensive price, to offer the cash back intermediation system that the real deal is generated between a member client and a member store, and to serve the advantage of the real deal to a user without limits of the time and place. CONSTITUTION: The member store issues a coupon and credit card slip, which shows the deal amount and serial number of the member client(1). The member client(2) connects to a server through the Internet or wireless cell-phone(3). The server asks to input the ID for the membership check of the member client via a display screen read from the first DB(5). If the member client is proved as a member, the second DB searches and reads the name, address, and telephone number of the member(6). The third DB requests for inputting the amount and serial number, which are marked on the coupon and credit card slip issued by the member store, checks if the inputted amount and serial number is matched with the amount and serial number saved on the forth DB(7). The member client checks the result via the Internet PC or wireless Internet cell-phone(8). After the check, the inputted contents are stored on the fifth DB(9). The member client requests the saved data via the wireless Internet cell-phone. The member store checks the asked data and offers the cash back service. The amount asked by the member client is subtracted and stored on the fifth DB.
