ASP.NET中的指纹读取器 [英] Fingerprint Reader in ASP.NET
问题描述
有人在ASP.NET应用程序中使用指纹扫描仪取得了成功吗?我正在寻找一种解决方案，用户可以在我们的Web应用程序中单击一个按钮，然后该按钮将触发本地安装的指纹读取器，获取指纹，然后将扫描的图像上传回服务器.
Has anyone had any success using a fingerprint scanner in an ASP.NET application? I am looking for a solution where a user would click a button in our web application that would then trigger a locally installed fingerprint reader, take the fingerprint and then upload the scanned image back to the server.
推荐答案
据我所知，有四种方法可以解决此问题:
To the best of my knowledge, there are four approaches to this:
- ActiveX控件(许多指纹读取器制造商提供了一个SDK).
- 用于其他浏览器的BHO和其他插件
- Web服务器可以基于IP地址调用的客户端上的服务器.
- 一个USB到以太网设备，可提供3个但以硬件形式.
每个都有优点和缺点，您需要对应用程序的细节进行分析.
Each has pros and cons, that you need to analyze with the particulars of your application.
但是，可能更好的解决方案是仅使用指纹读取器随附的自动化客户端.我见过的每个人都提供了某种机制来检测何时出现网页，扫描指纹并自动填写密码.您有理由不能将其与随机密码一起使用吗?
However, probably a better solution is simply to use the automation clients that come with fingerprint readers. Everyone I have seen provides some sort of mechanism to detect when a web page appears, scans a fingerprint, and automatically fills in a password. Is there a reason you can't use that with a random password?
