I wonder how this going to play out. It raised a lot of question though. So what if someone know you’re rich and have lots of money, they can chop off your hand and go shopping with it, AH! but wait, this thing actually scan pattern of your vein? so your hand have to be real, have to be still alive for that matter, so if someone chop off your hand and go scan it, it would not work would it. OK I feel safe now, hopefully that is what going to happen 🙂
