Ah, I believe (emphasis!) that the Android app just get’s validated and the card reader was just used on the PC. Like I said, I don’t really use it often (barely at all) and It looks like the key reader was used on the PC, NOT on the phone. I did test the reader with the phone and most of those tests where with @slava 's tools I now see … I wanted to dive into that some more, but got held up (starting a business).
Soo, I’m spreading FUD with the claim that the reader and the android app work together directly. I’d have to go through the process again to see just exactly works.
