I would like to be able to use a usb SmartCard reader/writer (NFC) using Flex but I cannot find out how to do it.
I know this approach does not seem the most secure, but I know that, for example, you can use with Flex a usb webcam if the users accepts to give that permission to the web application.
To give you a little background info about why I would need this: We have developped a web application which would be deployed in a local network of an enterprise and which server-side part is developped in java and which client side is developped in Flex. I have managed to use the reader/writer from the java part but that obviously is not practical as we can only use the tag reader/writer attached to the physical server. What we need is to be able to give the client the possibility to use the reader/writer connected to his PC. If needed, I would have total access to the client machines (if I need to give the application any kind of special permissions).
Thanks in advance for any clue you could give me!
You can't do anything in native Air, which would be the runtime that would expose such an API. You can do a native system app (Windows or Mac) and that app leverages two processes that communicate with eachother.
The main process would spawn two processes
So the main app would work as a HUB between the two.
Maybe it's worth to look at a FlashPlayer app that runs in the browser and communicates with a Java Applet via ExternalInterface.
