It looks like the SUPEREMA system does have a SDK
看起来SUPEREMA系统确实有一个SDK

However it doesn't integrate with PHP. The only way I can see of doing it would be to write a Visual Studio app that captured and updated to the database, or one with an embedded html browser that it could then send the captured data to.
但是它没有与 PHP 集成。我能看到的唯一方法是编写一个捕获并更新到数据库的 Visual Studio 应用程序，或者一个带有嵌入式 html 浏览器的应用程序，然后它可以将捕获的数据发送到。

Suprema includes now a Web Agent API with its SDK.
Suprema 现在包含一个带有 SDK 的 Web 代理 API。
The Web Agent they provide is a Windows-based application that acts like a mini-web-server on the client side on a specific port. e.g., https://localhost:5151.
他们提供的 Web 代理是一个基于 Windows 的应用程序，其作用类似于客户端特定端口上的微型 Web 服务器。例如，https://localhost:5151。
When a client visits your web application and they have the Web Agent up and running, you can do a cross-origin AJAX request with the help of Javascript to https://localhost:5151/scanthat would return a base64 encoded image of the fingerprint.
当客户端访问您的 Web 应用程序并且他们启动并运行了 Web 代理时，您可以在 Javascript 的帮助下执行跨源 AJAX 请求，以https://localhost:5151/scan返回指纹的 base64 编码图像。
Basically what they have done is to bridge the web browser to the internals of the client's computer.
基本上他们所做的是将网络浏览器桥接到客户端计算机的内部。
