The present invention relates to an electronic payment method and an electronic payment system using a multi-dimensional bar code. More specifically, the electronic payment method comprises: a first multi-dimensional bar code generating step of generating and outputting a first multi-dimensional bar code including at least one transaction information used for electronic payment with respect to a product purchased by a user; a transaction information obtaining step of obtaining at least one transaction information with respect to the purchased product included in the first multi-dimensional bar code by scanning and decoding the first multi-dimensional bar code; a security card information obtaining step of allowing a user terminal to obtain security card information by scanning and decoding a second multi-dimensional bar code generated and output to include the security card information of the user; a payment processing step of processing payment with respect to the purchased product by using the security card information; and a transmission-to-national tax service step of transmitting the transaction information to the server of the national tax service via a payment gateway (PG) server after the electronic payment with respect to the purchased product is completed. As configured above, the electronic payment method and the electronic payment system using a multi-dimensional bar code according to the present invention can improve the security of a security card by encoding security card information, which is used in a financial transaction on-line, to generate a multi-dimensional bar code, scanning and decoding the two-dimensional bar code to detect the security card information, and thereby processing electronic payment. |
