The finger print recognition is done on the device.
I have a few of them in my parts box, never got them to work with my fingers, or those of my wife. It usually takes 10 times or more to get a finger enrolled, and after that most of the attempts the finger is not read back correctly. I have three of them, all the same problem, so I consider them utter crap.
