Cipher input method and cipher key input device

Abstract

The invention relates to a code input method and a code key-pressing input device. The code input method includes the following steps: a first step, code signals are arranged in a same queue; a second step, the code signals are dynamically displayed and arranged randomly; a third step, code input is carried out according to a new code-signal arrangement sequence generated after the dynamic display. The code key-pressing input device comprises a code input part comprising a code-signal dynamic display part and input parts, the code signals displayed by the code-signal display part are randomly arranged in a queue, the input parts are arranged in a queue, and the keys of the input parts correspond to the code units displayed by the code-signal dynamic display part one by one. The method of the invention is smart, the structure of the device is simple and has low manufacturing cost, anti-peering effect is high with better theft-proof effect, and the operation of the device is also simple so as to complete code input promptly, with high practical value.

Description

technical field [0001] The present invention relates to a password input method and a password key input device, in particular to a password input method and a password key input device in which a password character and a key are independent, the sorting of the password character can be dynamically displayed and updated, and confirmation input is performed through the key . Background technique [0002] PIN pad is an identity verification input device widely used in electronic payment, and is widely used in transaction occasions such as banks, securities, stores, online shopping and mobile payment. In the prior art, the password input keys are arranged in a matrix, and the password characters are printed on the key positions of the keys, and the password characters are fixedly set along with the order of the key positions and lack of single change. The problem existing in the existing password keyboard is that the anti-theft performance is poor. Contents of the invention ...
