Abstract: A data input method, which is applied to an application chip and includes steps of: entering a secure input mode upon detecting a preset touch event; obtaining target information of a preset double-click event upon detecting the preset double-click event within a preset time period; sending the target information to a security chip and receiving target data corresponding to the target information returned by the security chip; and uploading the target data to an application layer upon detecting that an input is completed. In the present application, touch data detected based on a touch screen is filtered by means of the application chip, and only the detected target information is sent to the security chip for processing, and a multi-touch signal of the touch screen is processed by means of the security chip based on the software logic to determine the input data of the visually impaired user.

Abstract: A method for calibrating a battery level, an electronic device and a storage medium. The method includes steps of: obtaining a turn-off type when the electronic device is last turned off after the electronic device is turned on; and obtaining a current battery level of the electronic device based on turn-off time and a turn-off remaining battery level when the electronic device is last turned off in case that the turn-off type is a first type. The first type includes that the first battery supplies power to the charging management module but not to peripheral circuit module and the coulometer after the electronic device is turned off. Compared with the case in the prior art of the current battery level obtained by using an OCV curve, the current battery level obtained by using the turn-off time and turn-off remaining battery level at the last turn-off is more accurate.

Abstract: The present application relates to the technical field of point of sales, and provides a multi-touch data input method and device, a point of sale, and a computer-readable storage medium. The method includes: entering a security input mode when a preset touch event is detected; determining target information according to a preset double click event when the preset double click event is detected within a preset time period; determining a corresponding target data based on the target information and storing the target data; and uploading the target data to an application layer and exiting the security input mode when an input is detected to have been completed.

Abstract: The present application is applicable to the field of image processing technologies, and provides a face liveness detection method, a terminal device, and a non-transitory computer-readable storage medium. The method includes: obtaining an image to be processed, where the image to be processed includes a facial image; detecting a plurality of facial contour key points in the image to be processed; cropping the facial image in the image to be processed according to the plurality of facial contour key points; and inputting the facial image into a trained liveness detection architecture, and outputting a liveness detection result through the trained liveness detection architecture. An accuracy of face liveness detection may be effectively improved through the aforesaid face liveness detection method.

Abstract: The present application is applicable to the technical field of image processing, and provides a method and an apparatus for face detection, a terminal device, and a non-transitory computer-readable storage medium. The method includes: obtaining an image to be detected, where a first facial image is contained in the image to be detected; performing an initial detection on the image to be detected to obtain an initial detection result; comparing the first facial image in the image to be detected with a target facial image to obtain a comparison result, if the initial detection result indicates that the initial detection is passed; and determining a final face detection result of the image to be detected according to the comparison result. An accuracy of face detection can be effectively improved by performing the method for face detection.

Abstract: The present application provides a docking station and a POS machine using the same. The docking station includes a housing, a mainboard mounted inside the housing, a display device mounted on the housing, and a support configured to detachably support a card swiping device; the display device is mounted on the housing, the support is fixed on the housing, a data plug for connecting with the card swiping device is mounted inside the support, and the data plug is electrically connected with the mainboard. Such that the function of the card swiping device can be expanded and the docking station of the card swiping device is formed. By using the support to support the card swiping device, the occupied space can be reduced, and the use is convenient.

Abstract: A tablet POS terminal, comprises a casing, a tablet computer module arranged in the casing and an integrated payment module arranged in the casing; the casing is flat; a window for exposing a screen of the tablet computer module is correspondingly provided in the casing; the integrated payment module is arranged at one side of the tablet computer module; the integrated payment module is electrically connected with the tablet computer module; and a switch button configured to control powering on and off of the tablet computer module is provided at the casing.
