generally this kind of hardware secondary development interface, the hardware manufacturer should provide demo, LZ might as well ask the provider for more information.
I have always wondered how javaweb interacts with the bottom floor. The owner has the answer to share
this involves the browser. If IE uses ActiveX,firefox and chrome to use their respective plug-ins, I don't know if the manufacturer of the card reader you are using has developed these plug-ins. If not, you can only develop them yourself. In fact, the client browser uses the plug-in to read the information obtained by the card reader and then sends it to the server through a layer of transformation.
directly use the cloud service of Youyi Technology, support IC card reader in web, and support mainstream browsers such as IE,Chrome,Firefox,Safari,Opera, which is easy to use. For web development, please see http://www.youwokeji.com.cn/c...
need to install the browser plug-in provided by the card reader manufacturer, without which there is no permission and method to operate the device.
how to call, the vendor will provide API documents.
ask for answers.
it's easy to write a desktop application that calls the manufacturer's SDK to read the card and implements a Web Host to listen to http requests from the native (127.0.0.1). In this way, you can initiate an ajax request from the browser to the address, read it from the desktop application, and then return it by json.
