C#编程指南：利用ASP.NET和JavaScript实现带有Fingerprint功能的Web应用登录系统

我正在使用3M Cogent CSD 200型指纹读取器设备
希望您已经拥有SDK以下是此设备的一些代码，用于捕获和匹配详细信息以允许登录。
两个function在这里
1.]捕获 &＃8211; 保存指纹
2.]匹配 &＃8211; 在登录时匹配fingetprint
注意：它是我的应用程序中的代码块，您必须根据您的应用程序进行调整

上述就是C#学习教程：使用asp.net C＃Javascript登录使用Finerprint的Asp.net Web应用程序分享的全部内容，如果对大家有所用处且需要了解更多关于C#学习教程，希望大家多多关注&＃8212;编程笔记
