Is it possible to access hardware devices (web-cams, magnetic card readers, etc.) from within Internet explorer?
If yes, what technologies are used? And are there any .Net examples.
In my case, I need to access a magnetic card reader that would be attached to the client computer. The web-app would need to be able to access the reader and get the card information, which will then be used to access data-tables from a database running on the server.
I have seen web-cams that are integrated into websites, was wondering how that is done? Because if web-cams can be accessed, so should any other device attached to a USB port.
Finally, can SilverLight applications access hardware? Can they print to an attached printer?
Custom ActiveX control is probably your best bet
