Zusammenfassung:	A system and a method for delivering card information using a voice signal are provided to transform encrypted code information into a voice signal to be transferred to a communication network, and allow a card information recognition server to recognize the voice signal to recover the card information so that credit card settlement is approved. A start button is pressed to start outputting card information or a starting signal is detected by a high frequency detector(S301). An event counter and time information are provided if the starting signal is detected, and a disposable encryption key is randomly made(S302). A character/number information code string is made by performing encryption using the disposable encryption key in order to prevent information drain(S304). Transfer error check codes for the character/number information code string are made and a transmit data code string is made(S306). A voice signal is synthesized according to cords of transmission data, or extracted from a sound source database. The sound signal is output through a speaker(S309).
