Abstract
Disclosed are a complex payment system using a portable terminal, and a complex payment method. According to the present invention, a portable terminal such as a smartphone or a vendor server may analyze and display an optimum payment condition containing a minimum payment amount using bonus information such as card information, discount information, membership point information, or coupon information when a user pays, thus preventing personal information leakage and enabling the user to pay a minimum amount by means of his/her credit card using the bonus information.
