PURPOSE: A smartphone recognition system based on audibility frequencies and a smartphone recognition method using the same are provided to recognize a target smartphone within a predetermined distance by using a sound wave. CONSTITUTION: One or more clients(200) generate an audibility frequency by using a key value or a synchronization value for recognizing an opponent. One or more clients recognize the audibility frequency generated by the opponent. Each of the clients recognizes a key value or a synchronization key value by using the audibility frequency transmitted by the opponent. A server(100) receives an unique ID(Identification) and a key value from the client. The server transmits the client information to the client.
