A near field communication method, comprising: periodically acquiring, by a first touch screen terminal, self-capacitance data of the first touch screen terminal; periodically acquiring, by the first touch screen terminal, full-screen driving data and sensing data; calculating a difference between driving data of neighboring driving electrodes, and a difference between sensing data of neighboring sensing electrodes; making a sum of absolute values of the difference of the driving data and the difference of the sensing data to obtain a consistency value of the self-capacitance data; judging whether the consistency value of the self-capacitance data is less than a predetermined consistency threshold; judging whether the self-capacitance data satisfies a large-area contact condition if the consistency value of the self-capacitance data is less than the predetermined consistency threshold, or judging that the second touch screen terminal having a large-area contact is not present if the consistency value of the self-capacitance data is not less than the predetermined consistency threshold (S103, S104); if the second touch screen terminal having the large-area contact is detected, performing, by the first touch screen terminal, an approaching detection for the second touch screen terminal by using a first signal strength threshold, otherwise, performing an approaching detection for the second touch screen terminal by using a second signal strength threshold, wherein the second signal strength threshold is greater than the first signal strength threshold (S105, S106, S107, S108, S109); and when the approaching detection is successful, carrying out data transmission with the second touch screen terminal (S50, S60). periodically acquiring, by a first touch screen terminal, self-capacitance data of the first touch screen terminal; periodically acquiring, by the first touch screen terminal, full-screen driving data and sensing data; calculating a difference between driving data of neighboring driving electrodes, and a difference between sensing data of neighboring sensing electrodes; making a sum of absolute values of the difference of the driving data and the difference of the sensing data to obtain a consistency value of the self-capacitance data; judging whether the consistency value of the self-capacitance data is less than a predetermined consistency threshold; judging whether the self-capacitance data satisfies a large-area contact condition if the consistency value of the self-capacitance data is less than the predetermined consistency threshold, or judging that the second touch screen terminal having a large-area contact is not present if the consistency value of the self-capacitance data is not less than the predetermined consistency threshold (S103, S104); if the second touch screen terminal having the large-area contact is detected, performing, by the first touch screen terminal, an approaching detection for the second touch screen terminal by using a first signal strength threshold, otherwise, performing an approaching detection for the second touch screen terminal by using a second signal strength threshold, wherein the second signal strength threshold is greater than the first signal strength threshold (S105, S106, S107, S108, S109); and when the approaching detection is successful, carrying out data transmission with the second touch screen terminal (S50, S60).
