推荐答案

您需要在此处提供其他信息，因为传统的Web应用程序无法直接连接到客户端设备.

通常，服务器上的Web应用程序与计算机进行通信的方式是通过Web浏览器.假设您期望将读卡器安装在客户端，则需要通过Web界面与Web浏览器进行通信.

如果仅是数据库的共同点(数据库中的考勤卡记录数据，而ASP.NET则显示数据库中存储的数据)，则需要确保该数据库对于两个服务器或在不同服务器上都是公用的，但同步.

You''ll need to provide additional information here because traditional web applications do not connect directly to client devices.

Mostly the way for a web application on a server to communicate to a computer is through a web browser. Assuming, you are expecting the card reader installed at the client you would need to communicate via web interface with the web browser.

If it''s just the database that is a common point (attendance card logging data in DB and ASP.NET shows the data stored in DB), then you need to make sure that the database is common for both or at different servers but in sync.
