User information exchange method between smart electronic equipment located in short distance

PURPOSE: A user information exchange method between smart apparatuses is provided to improve the convenience of information exchange by receiving user information of a smart electronic apparatus through a user information management application installed in the smart electronic apparatus. CONSTITUTION: A sound wave signal creation unit(230) creates sound wave signals of an audible frequency boundary band for user identification information. A speaker(240) outputs the sound wave signal. A microphone unit(250) receives the sound wave signal. A filter unit(260) filters a sound source of the audible frequency boundary band from the sound wave signal. A sound source analysis unit(270) extracts the user identification information by analyzing the filtered sound source signal. A communication unit(210) transmits data to a management server and receives the data from the management server(100).
