A dual-chip point-of-sale terminal, comprising a security chip, an application chip, and a computer program stored in and executable on the security chip and the application chip, wherein the application chip, when executing the computer program, is configured to implement operations that comprise:
- entering, upon detecting a preset touch event, a secure input mode;
- obtaining, upon detecting a preset double-click event within a preset time period, target information of the preset double-click event;
- sending the target information to the security chip, and receiving target data corresponding to the target information returned by the security chip;
- and
- uploading, upon detecting that an input is completed, the target data to an application layer;
- wherein the secure input mode refers to a situation where the target information obtained by the application chip is sent to the security chip and processed by the security chip, to determine a data input mode of corresponding password information;
- wherein said entering, upon detecting the preset touch event, the secure input mode comprises:
- obtaining, upon detecting a touch event and the touch event is a moving event, first position information of the touch event;
- determining an occurrence time and an end time of the touch event when the first position information is detected to be located in a data input area;
- determining a touch duration according to the occurrence time and the end time;
- and
- determining the touch event to be the preset touch event when the touch duration is detected to be greater than or equal to a preset touch duration and entering the secure input mode;
- wherein said obtaining, upon detecting the preset double-click event within the preset time period, the target information of the preset double-click event, comprises:
- obtaining, each time a double-click event is detected within the preset time period, second position information of the double-click event;
- determining the double-click event to be the preset double-click event when the second position information is detected to be located in the data input area and taking the second position information as the target information;
- and
- obtaining all of the target information detected within the preset time period;
- and
- wherein the security chip, when executing the computer program, is configured to implement operations that comprise:
- receiving position range information of multiple preset input regions of the data input area sent by the application chip;
- assigning each of the multiple preset input regions with corresponding preset data, and establishing an association relationship between the multiple preset input regions and the corresponding preset data to obtain a preset data query table;
- determining, upon receiving the target information sent by the application chip, the target data corresponding to the target information based on the preset data query table;
- and
- sending the target data to the application chip.
