Technical Field
[0001] This utility model relates to a security POS machine that prevents peeping. Background Technology
[0002] A POS machine is a device that enables electronic payments and bank card transactions, and is widely used in commerce and service industries. A POS machine typically consists of a main body, display screen, keyboard, card reader, and paper output slot. The keyboard is used to input PINs or other information, the card reader is used to read bank card information, and the paper output slot is used to print transaction receipts.
[0003] Traditional POS machines have some shortcomings, such as:
[0004] Traditional POS machines use a fixed-arrange numeric keypad for PIN input, making it easy for others to spy on or record the PIN; traditional POS machines also use a regular display screen to show information, making it easy for others to spy on or photograph the information.
[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as implying any subjective intent. Utility Model Content
[0006] In view of the above, the purpose of this utility model is to provide a spyproof security POS machine to solve at least one of the problems that have occurred under the existing conditions.
[0007] The technical solution adopted to achieve the purpose of this utility model is an anti-peeping security POS machine, including a POS machine body, a protective device, a touch screen numeric keypad with randomly arranged numeric keys, and a microcontroller. The POS machine body has slots on both sides for installing the protective device. The protective device includes a protective cover, a transmission gear, a motor, and an infrared sensor. The motor is located inside the POS machine body, and the transmission gear is located on the motor shaft. The protective cover is U-shaped, and baffles on both sides of the protective cover are located in the slots on both sides of the POS machine body. A rotating gear is located on the protective cover, on one side of the baffle, and connected to the transmission gear. The infrared sensor is located on the keyboard area of the POS machine body, on the left and right sides of the keyboard area. The touch screen numeric keypad is located on the keyboard area of the POS machine body. The microcontroller is located inside the POS machine body and is electrically connected to the motor, the infrared sensor, and the touch screen numeric keypad.
[0008] Furthermore, the protective cover is made of light-shielding material.
[0009] Furthermore, the height of the protective cover is greater than the height of the POS machine body.
[0010] Furthermore, the touchscreen numeric keypad is equipped with a privacy film with a viewing angle of 60 degrees.
[0011] Furthermore, the anti-peeping security POS machine body also includes a flexible cloth, one end of which is connected to the protective cover and the other end of which is connected to the POS machine body.
[0012] The beneficial effects of this utility model are:
[0013] 1. By setting up a protective cover made of retractable U-shaped light-blocking material and a touch screen keypad with privacy film and random arrangement function, the process and result of users entering passwords or other information can be effectively protected and hidden.
[0014] 2. By setting up a motor-driven transmission gear to drive the rotating gear, the protective cover can be raised and lowered, thus achieving control of the protective cover. This simplifies the structure, reduces costs, and improves efficiency.
[0015] 2. By setting up an infrared sensor to detect whether the user is operating the touch screen numeric keypad, and controlling the motor and the touch screen numeric keypad's on / off state based on the detection result, power is saved and service life is extended. Attached Figure Description

[0021] The present invention will now be described in this embodiment with reference to the accompanying drawings and some embodiments.
[0022] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of this application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and embodiments.
[0023] Figure 1-3 A spy-proof security POS machine includes a POS machine body, characterized by: a protective device, a touchscreen numeric keypad with randomly arranged numeric keys, and a microcontroller; the POS machine body has slots on both sides for installing the protective device; the protective device includes a protective cover, a transmission gear, a motor, and an infrared sensor; the motor is located inside the POS machine body, and the transmission gear is mounted on the motor shaft; the protective cover is U-shaped, with baffles on both sides of the protective cover located in the slots on both sides of the POS machine body, and a rotating gear is mounted on the protective cover, located on a baffle on one side of the protective cover, and connected to the transmission gear; the infrared sensor is located on the keyboard area of the POS machine body, on the left and right sides of the keyboard area; the touchscreen numeric keypad is located on the keyboard area of the POS machine body; the microcontroller is located inside the POS machine body and is electrically connected to the motor, the infrared sensor, and the touchscreen numeric keypad.
[0024] When this invention is in operation and the POS machine is not in use, the microcontroller controls the motor to drive the transmission gear, which in turn drives the rotating gear to move the protective cover downwards to a retracted state, thus turning off the touchscreen keypad. This saves power and prevents accidental touches or damage to the touchscreen keypad.
[0025] When the POS machine is needed, the user simply inserts their bank card into the card reader. The microcontroller then controls a motor to drive a transmission gear, which in turn rotates the protective cover upwards to open, activating the touchscreen keypad. This protects user privacy while allowing for convenient input of passwords or other information.
[0026] When entering passwords or other information, users simply insert their fingers inside the protective cover to operate the touchscreen keypad. Because the cover is U-shaped and made of light-blocking material, and its height exceeds that of the POS machine, it effectively blocks the view of others or recording devices, thus ensuring the security of the user's password or other information. Furthermore, the touchscreen keypad has a privacy screen protector with a limited viewing angle, ensuring that the displayed content is only clearly visible from a position directly facing the keypad, further enhancing its anti-peeping function.
[0027] Additionally, after each password entry, the microcontroller can rearrange the randomly arranged numeric keys on the touchscreen keypad. This avoids the risk of password recording or cracking that can occur with a fixed numeric keypad.
[0028] This invention also includes a flexible fabric, one end of which is connected to the protective cover, and the other end is connected to the POS machine. The flexible fabric can cover the POS machine when the protective cover is unfolded, increasing aesthetics and comfort without affecting user operation.
