The present invention relates to an authentication method using an NFC authentication card, which is structured to allow two-factor authentication by providing an NFC authentication card for communicating with a wireless terminal via NFC, and to utilize a OTP or a transaction-linked OTP number generated by the NFC authentication card, so as to enable two-factor authentication using a single NFC authentication card, thereby effectively rendering carrying of a separate authentication means unnecessary, further enhancing security by allowing Internet banking through primary and secondary authentication, easily verifying transaction results by authenticating via the transaction-linked OTP, and eliminating the need for a user to manually input transaction information. |
