The utility model discloses a password peep-resisting system capable of being used in an automatic teller machine (ATM), which comprises a liquid crystal panel, a polarization analyzing polarizer, a backlight module, a polarizing polarizer, an installation plate, a dynamic palm keyboard and a dynamic password control system. Two ends of the installation plate are fixed on two lateral walls of the upper portion of a cabinet body of the ATM in sliding mode. When the position is fixed, the polarizing polarizer is parallel to a liquid crystal display screen and perpendicular to the visual line of a user, the polarization angle is right perpendicular to the angle of the polarization analyzing polarizer in the liquid crystal display screen. A plurality of blank keys are arranged on the dynamic palm keyboard according to the requirements of number keys of 0 to 9 and a plurality of function keys, and any one of the number keys of 0 to 9 or any one of the function keys is controlled by the dynamic password control system to be displayed on the liquid crystal display screen, and the user can see the number only when the visual line of the user and the polarizing polarizer are perpendicular to the liquid crystal display screen. The password peep-resisting system capable of being used in the ATM is remarkable in effect of avoiding peep of passwords, convenient to use, simple in structure, complete and stable in system, easy to install and low in manufacture cost.
