A method and a system for paying purchase goods in a shopping mall are provided to directly calculate the purchase goods of a customer in a counter without putting out the goods from a shopping cart by reading barcode or RFID(Radio Frequency IDentification) tag information from a cart terminal. Each shopping cart(10) includes an RFID terminal(100) generating and storing a purchase goods list by reading a barcode or RFID tag of the goods, and transmitting the purchase goods list through the RF network. Each RF receiver(20) receives data from the RFID terminal in the shopping mall and transmits the received data to a shopping mall server(30) through the wired/wireless network. The shopping mall server stores and manages the data received from the RF receiver by each RFID terminal. A POS(Point Of Sale) terminal(210) is installed to the counter(40), receives the data of the RFID terminal from the shopping mall server by inputting an ID of the RFID terminal, displays the received data to a screen, and issues a receipt.
