PURPOSE: A combined wire-wireless method which uses an OTP is provided to decode a token code transmitted from a wireless terminal of a client, thereby authenticating financial transaction data transmitted from a wired terminal of the client. CONSTITUTION: Information about a program, installed on a wireless terminal of a client, which dynamically generates an OTP is mapped with client information which identifies the client through storage media. The client information connecting through a wired terminal is confirmed. The OTP dynamically generated through the program mapped with the client information is received. If validity of the OTP is authenticated, validity of the client connecting through the wired terminal is authenticated(545). |
