A financial transaction authentication method through interactive transceiving is provided to increase safety of a financial transaction, thereby preventing financial transaction damage due to robbery or loss of a card. A central control server receives basic data and authentication data of a financial trader in advance. A financial transaction device receives basic data and user data of a real transaction user during financial transaction(S200). The central control server displays the transmitted user data and the received authentication data to a terminal of an authentication clerk(S300). When a transaction approval or a transaction cancel signal is inputted to the terminal of the authentication clerk, the central control server authenticates or cancels the financial transaction. The central control server transmits authentication information or cancel information to the financial transaction device(S400). |
