Embodiments of the present invention disclose a data transmission method, a terminal, and a data transmission system, where the data transmission method includes: acquiring, by a first terminal, an output signal of a sensor of the first terminal, where the output signal of the sensor of the first terminal is a signal generated when a first magnet of a second terminal triggers the sensor of the first terminal; determining, by the first terminal, the output signal of the sensor of the first terminal as a low-level output signal; establishing, by the first terminal, a communication link with the second terminal; and determining, by the first terminal according to the communication link established by the first terminal with the second terminal, to perform data transmission with the second terminal. Because it is only required that a magnet of the second terminal should trigger the sensor of the first terminal so that the sensor of the first terminal outputs the low-level output signal, the first terminal can establish the communication link with the second terminal, which simplifies a user operation, and resolves a problem in an existing data transmission method that data transmission time is prolonged because relatively long time is taken due to a cumbersome user operation. |
