Peep-proof plate for ATM machine keys

Abstract

The invention discloses a peep-proof plate for ATM machine keys, and the peep-proof plate comprises a peep-proof plate and a housing (2). The peep-proof plate is fixed at the upper part of the housing (2), and is located exactly above the ATM machine keys. The housing (2) is made of a square lightproof material. The peep-proof plate comprises a nonopaque panel (1) with the thickness of 3-8mm and an acrylic thick plate (4) with the thickness of 10-60mm. The panel (1) is attached to the upper surface of the acrylic thick plate (4), and at least ten lightproof films (3) which are arranged in a parallel manner at uniform intervals are embedded in the direction perpendicular to the acrylic thick plate (4), wherein the intervals between the lightproof films (3) is 3-8mm. The arrangement direction of the lightproof films (3) is parallel to the eyes of an operator, and the thickness of each lightproof film (3) is 0.1-0.5mm. According to the embodiment of the invention, the peep-proof plate enables the operator to be able to clearly see the ATM machine keys without obstacles in the vertical direction, also completely blocks the peep of the finger movements of the operator in other directions, is simple in structure, is low in manufacturing cost, and is very good in application prospect.

Description

technical field [0001] The invention relates to an anti-peeping panel for keys of an ATM machine, in particular to a protective cover plate installed on the keys of a bank ATM machine or a cipher machine, and belongs to the technical field of security equipment in the financial industry. Background technique [0002] As the use of computer technology becomes more and more mature, ATM machine input keyboards, bank counter password input devices and POS machines are becoming more and more popular in people's daily life. At present, the commonly used methods to prevent others from peeping when ATM machines and POS machines perform password input operations are: setting a distance of one meter to prevent others from peeking at the password operation keyboard, but the one-meter line cannot effectively prevent others from peeping. Another way is as figure 1 As shown, a protective cover is covered on the base plate with the button area, and the lower side of the protective cover i...

Problems solved by technology

At present, the commonly used methods to prevent others from peeping when ATM machines and POS machines perform password input operations are: setting a distance of one meter to prevent others from peeking at the password operation keyboard, but the one-meter line cannot effectively prevent others from peeping

Another way is as figure 1 As shown, a protective cover is covered on the base plate with the button area, and the lower side of the protective cover is provided with an operation port for the user to operate the key, and the protective cover can connect the upper side, left side, right The side and top of the square are completely covered to prevent others from peeping from the above four directions; however, the cost of the ATM key shield is relatively high, and when the user enters the password, it will cause obstacles that block the user's sight, which affects the work efficiency

Therefore, existing ATM machine and POS machine carry out the password button device of password input operation and can not make the user carry out effective and convenient operation, and do not have effective device and can prevent other people from peeping, easily reveal password when user inputs password, cause security incident

[0003] The utility model patent "An Anti-Peeping ATM Keypad Protective Shell" (201420615788.2) cannot prevent outsiders from spying on the operator's keystrokes from behind; , the disadvantage is that the mirror is easy to get dirty, and the structure is relatively complicated; the loose-leaf type rotatable or adjustable angle baffle disclosed in the new patent "Password Key Anti-Peeping Device" (201320573140.9) and "Key Input Password Privacy Cover" (200520108644.9) , its shortcoming is that because the baffle needs sufficient structural strength, it will be made relatively thick. If the number of baffles is set small, the anti-peep effect will not be achieved, but if there are too many baffles, it will hinder the user's gaze and attention. Operation, on the other hand, after a long period of use, the angle adjustment mechanism of the baffle plate will be unable to adjust due to wear and tear, so its practicality is not strong; even if it can be adjusted, when operating, fingers or the back of the hand will accidentally Touching the baffle may be more conducive to peepers getting a more suitable viewing angle

Others, such as the invention patent "An Anti-peeping Password Input Method" (201410796880.8) adopts a combination of randomly changing character key position technology and directional display technology. The structure is complex, the operation efficiency is low when used, and the practicability is not strong.
