Okay, I've read both the tutorial and, as much as I can, the app notes from ZianTech (not what I'd call a user's manual). My confusion is on where the finger print is verified. Is it done in the sensor or at the micro controller (or whatever computer)? If it's done at the sensor it seems I could just rip the sucker out and wire in my own controller and lie to the other end. I guess if I was running a two (or even three) factor authentication and just let it tell me, using 1:N, which print it is.
Am I correct in my interpretation? Or have missed something along the way? Not that that would be the first time :o
