Key module based on fluorescence identification, preparation method and code keyboard

Abstract

The invention discloses a key module based on fluorescence identification. The key module comprises a module body, wherein a character groove is formed in the upper surface of the module body, and therecess position of the character groove is covered with a fluorescent coating. The invention also discloses a preparation method of the key module. The preparation method comprises the following steps that fluorescent powder and a precipitation-preventing particle agent are evenly mixed to prepare a mixture; the recess position of the character groove is covered with a fluorescent powder adhesive; an adhesive gun is adopted to cast the mixture into the recess position of the character groove; the dried mixture is sprayed with a transparent waterproof film. The invention also discloses a codekeyboard of a financial device. The key module is arranged on the code keyboard. The problem that a keyboard character is poor in light sensitivity and easily causes operation errors of a client can be effectively solved by adopting the key module.

Description

1. Technical field [0001] The invention relates to financial equipment, in particular to a key module based on fluorescence identification, a preparation method and a password keyboard. 2.
