PROBLEM TO BE SOLVED: To provide an authentication method that uses an NFC authentication card.SOLUTION: The present invention provides an authentication method that uses an NFC authentication card, which is configured to enable two-factor authentication by providing an NFC authentication card for communicating with a wireless terminal via NFC, and utilizing an OTP or transaction-linked OTP number generated by the NFC authentication card. Enabling the two-factor authentication using a single NFC authentication card effectively makes it unnecessary to carry separate means of authentication, enhances security further by enabling Internet banking through primary and secondary authentication, allows for easily verifying transaction results by authenticating via the transaction-linked OTP, and eliminates the need for users to manually input transaction information.SELECTED DRAWING: Figure 1 |
