The present invention relates to the technical field of near field communication. Provided are a capacitive touch screen terminal and near field communication method and system thereof. In the method and system, a sending terminal and a receiving terminal multiplex a driving electrode and an inductive electrode of a touch sensor in a capacitive touch screen for achieving near field communication, and use a frequency sequence as a carrier for transmitting data. Compared with the electrostatic field detection method used in the prior art, the present invention is suitable for near field communication between two capacitive touch screen terminals having a large difference in size; moreover, after starting the near field communication, the two capacitive touch screens can accurately identify whether the change of electrostatic field is caused by the approach of a conductor such as a hand, or caused by a terminal in communication therewith, thus improving the reliability upon the start of data transmission and optimizing user experience. |
