Abstract

The present invention discloses a code keyboard, to resolve prior-art technical problems that a code keyboard is not durable, high in costs and weak in environmental suitability. The code keyboard comprises: at least one digital display module. The digital display module is used for displaying a random character output by a controller. Each digital display module is corresponding to one key, and each digital display module is corresponding to an operational zone of the key. The key is used for detecting whether a user selects the digital display module, and outputting a selection signal when determining that the user selects the digital display module. The controller is used for receiving the selection signal, and determining, based on the character displayed by the digital display moduleand the selection signal, a character entered by the user.

Description

technical field [0001] The invention relates to the technical field of keyboards, in particular to a password keyboard. Background technique [0002] With the widespread use of passwords, the problem of password leakage is also becoming more and more serious. [0003] In an ATM machine or an access control system, since the digital position of the keyboard is fixed, a stealer can quickly steal the user's password by obtaining the user's operating position. [0004] In the prior art, in order to solve the above-mentioned problems, a graphical random password keyboard is usually used, that is, a keyboard whose number position can be freely changed on a liquid crystal screen. [0005] However, keyboards made of such liquid crystal screens often have high environmental requirements. For example, when the temperature in the north is low, such keyboards are often unusable, and keyboards made of liquid crystal screens are expensive and easily damaged. [0006] In view of this, ho...
