使用asp.net登錄到Asp.net Web應用程序使用Finerprint C＃Javascript

Question

我想使用指紋登錄到我的asp.net Web應用程序。這意味着我不想使用任何登錄ID和密碼。我只想用我的指紋登錄。我有一個3米高的設備，設備工作正常，但我不知道如何將設備與我的軟件集成。我正在使用ActiveX。

我的JavaScript代碼是：

<script type="text/javascript"> 

    $(document).ready(function() { 
     $('#scan').click(function() { 
      $('#dicscan').addClass('scanning'); 
      setTimeout(function() { 
       $('#dicscan').removeClass('scanning'); 
      }, 20 * 1000); 
     }); 
    }); 
</script> 
<script type="text/javascript"> 
    function OpenActiveX() { 
     var port = document.getElementById("Comport"); 
     port.Conopen = 1; 
     if (port.error > 0) //Display errors if found 
      alert(port.ErrorDescription); 
    } 

    function Matching() { 
     var retval = 0; 
     var port = document.getElementById("Comport"); 
     port.Ksserialnumber = 1; 
     port.KsCapture = 1; 
     port.KsAuthenticationMatch = 1; 
     retval = port.KsMatchretvalue; 
     if (retval > 0) { 
      alert("Two fingers are Matched..."); 
      window.open('ResultPage.html', '_self'); 
     } 
     else { 
      alert("Finger Not Matched..."); 
     } 
     if (port.error > 0) //Display errors if found 
      alert(port.ErrorDescription); 
    } 
</script> 

我在port.KsMatchretvalue越來越不確定。

我使用3M切實CSD 200型指紋讀取裝置
希望你有SDK已經 下面是該裝置來捕獲和比賽的細節，使日誌在一個小的代碼。
這裏的兩個功能
1]捕獲 - 保存指紋
2]比賽 - 在日誌的時間
注意匹配fingetprint：從我的應用程序的代碼塊，你必須根據進行了調整您的應用程序
