A method for data transmission between terminals, applied between a first terminal and a second terminal, said first terminal equipped with a first capacitive touch screen and said second terminal equipped with a second capacitive touch screen, comprising: said first terminal transforming information to be transferred into binary data, and accordingly applying a voltage to electrodes involved in data transmission on said first capacitive touch screen, and forming corresponding electric field distribution information; when said first capacitive touch screen contacts with said second capacitive touch screen, said second terminal decoding said information to be transferred according to detected electric field distribution information currently on said first capacitive touch screen; wherein before said first terminal transforms said information to be transferred into binary data, the method further comprises: said first terminal informing said second terminal of notification information, comprising: electric field range, distance between electrodes, the number of row electrodes and column electrodes, and electrodes involved in data transmission; wherein, said first terminal applies a voltage to edge row electrodes and column electrodes on said first capacitive touch screen, and informs said second terminal of an electric field range on said first terminal; said first terminal applies a voltage to all of row electrodes and all of column electrodes on said first capacitive touch screen, and informing said second terminal of the number of corresponding electrodes and a distance between electrodes on said first terminal; said first terminal applies a voltage to row electrodes or column electrodes involved in said data transmission, and informs said second terminal of the electrodes involved in said data transmission on said first capacitive touch screen;
