The invention relates to the electronic field, in particular to a data transmission technology. An intelligent data input tool is provided with a touch screen. A data receiving program is arranged in the intelligent data input tool. The data receiving program contains an action instruction receiving determination program which is used for judging whether operation action information of a user through the touch screen conforms to a preset data receiving instruction; if yes, preparation is made to receive a data link in a first transmission mode; and after receiving of the data link is completed, the data link is opened, and to-be-transmitted data is read in a second transmission mode.
