[0002] The abbreviation of POS (Point of sales), which means point of sale terminal in Chinese, the traditional POS machine structure, which includes a housing for each functional module, a control board that is adapted to be installed with the housing, and the display screen is fixed on the control board , and connected to the control circuit through a cable, but today's POS terminal is not safe to use, there is no blocking device, and some customers are not used to covering it with their hands, which will easily lead to password leakage

[0003] The patent with the publication number CN207115651U discloses a security POS machine, which includes a casing, and a circuit board is arranged inside the casing, and the circuit board is connected with a display block, an input keyboard, and a card reader slot. When entering the password, the keyboard needs to be moved back and forth, and there are input keyboard baffles on the front and left and right sides of the keyboard to ensure that it is not easy to be peeped when the password is entered, but the baffle of the device is fixed, so that the POS machine body It takes up a lot of space, and the bezel will also block the display interface. When the password is not entered, the display interface will be blocked and affect the use, so it cannot meet the needs of use, and there is room for improvement
