PURPOSE: A data transfer system and a method thereof are provided to recognize user input through a camera and to transfer data according to user input between devices having the camera. CONSTITUTION: A first device(10) generates images including an operation generating unit of a user by using a first camera. The first device detects the operation generating unit as an image and recognizes a data selection operation. The first device moves a cursor and recognizes selected data according to the data selection operation. If the operation generating unit is recognized through a second camera, a second device(20) receives data from the first device. The first and second devices are registered in a data relay server(40). [Reference numerals] (40) Data relay server; (AA) Communication network
