如何将指纹扫描仪SDK与VB.NET应用程序集成 [英] How to integrate Fingerprint scanner SDK with VB.NET application

问题描述

我已经购买了指纹扫描仪设备 STARTEK，型号:FM220 ，以与在 VB.NET 中开发的应用程序集成.我正在寻找完整的SDK与应用程序集成.我从以下位置找到了SDK: SDK Startek，FM220 .该SDK允许操作一些功能，例如 ConnectDevice，GetTemplate，GetImagequality 等.但是，与用户指纹匹配最重要的功能是进行身份验证，即与ISO模板匹配的功能(以字节格式返回)通过应用程序.

I have bought a fingerprint scanner device STARTEK,model:FM220 to integrate with a application which is developed in VB.NET. I am searching for the full fledged SDK to integrate with the application. I found the SDK from here: SDK Startek,FM220. The SDK allows to operate few functions like ConnectDevice, GetTemplate, GetImagequality etc. But the function which was most important to match the user's fingerprint is to authenticate i.e function to match the ISO Template (returning in byte format) by the application.

任何人都可以帮助我解决此问题.

So can anyone help me out to solve this issue.

推荐答案

看起来像这部分

Public Sub ScanCompleteFM220(result As FM220_Capture_Result) Implements FM220_Scanner_Interface.ScanCompleteFM220
    'HANDLE CROSS THREAD OPERATIONS.......................
    If result.getResult() Then
        Dim tmpl As String = Convert.ToBase64String(result.getISO_Template())    ' <--- THIS LINE

将扫描结果转换为BASE64字符串.

converts the result of the scan to a BASE64 string.

因此，您可以在指纹注册过程中将此字符串保存到数据库中.验证时，从数据库中搜索该字符串.

So you can save this string to a database during fingerprint enrolment. When validating, search for this string from your database.
