Recently doing a scan code login function, for this i also searched the internet about the implementation of the scan Login. When this function was completed, I decided to organize the whole realization, so that I can see it later and also facilitate other programs with similar Requirements.To implement a scan login we need to address two issues:1. How do I resolve a privilege security issue without entering a username and password? In other words, ho
