Ruby on Rails Thursday, May 31, 2012

Assuming that you want to use it within the browser, I'm afraid you have to create another program for that.

I've seen people create a Java Applet to access external devices from the browser. That I known it will work.

But assuming you just want to integrate biometrics data monitoring and visualization, I believe that the best way is to create a
diferent desktop/embedded application just to communicate with the server and register the data.

I haven't worked with any of those, but I have worked with bar-code scanners, and the way they work is that they basically emulate a keyboard typing really quickly. You click or tab into the text field that the bar-code belongs in, and pull the trigger, and the code is inserted in the text field.

Assuming that you want the device connected to the client PC (rather
than the server) then you could have a problem accessing it from the
browser.
