Manufacture method for peep-proof password input device

Abstract

The invention relates to a manufacture method for a peep-proof password input device. An existing waste mobile phone screen is used and is transformed, a polaroid on the top layer of the liquid crystal display screen of a mobile phone is removed, the screen which can be seen at present is a white screen, the removed polaroid on the top layer is manufactured into polarized glasses, the polarized glasses need to be worn if a user wants to clearly see contents on the display, and the function can effectively control a visible range so as to perform a peep-proof effect; and the screen touch function of the mobile phone screen can be retained and is combined with a random keyboard to directly input a password on the screen. Compared with the own entity keyboard of a general payment POS (Point-Of-Sale) terminal used in supermarkets and markets, the random keyboard can improve security, and payment is safer; a smartphone can be connected with a network to be favorably connected with a payment system; various types of APPs can be downloaded and installed to integrate with life so as to enable the input device to be more intelligent; and by use of the design, obsolete old mobile phones can be reused, cost can be greatly lowered, and the design more conforms to the concept of environmental protection.

Description

technical field [0001] The invention relates to the technical field of password input devices, in particular to a manufacturing method of an anti-peeping password input device. Background technique [0002] Today in the age of electronic commerce, all kinds of microcomputers popularized at home and abroad, especially computer network services, cannot do without the use of password input devices that can input information codes.
