I think as usual, the Apple product is brilliant. This is not a Apple watch but this is ApplePay coming to your existing phone for those of us who did not get their phones upgraded to the 6 series yet. Very well done indeed. The idea of detecting the user is very important as well, I am not sure the method that they applied but I am hoping that they have included biometrics in their implementation and not a very simple mechanism of just opening the latch or just a warm body as all of these would be invitation for trouble. There are many sensors today that could measure some of the vital signs and could help in that authentication process already. I am almost sure that Apple would have incorporated the latest and greatest as they typically do not go cheap. I am still a bit concerned about two things, the enrollment process, everyone is still talking about the yellow path and now you do not have touch ID, you may be making this a bit more accessible to hackers with the old phones that could afford only a watch in lieu of iPhone 6 And the second, the unlocking of the watch, I hope it is a secure mechanism and it is not a mediocre 4 digit PIN, if you loose your PIN you may be losing a lot of cash, it is not simply the watch that you are losing. It is a new world and it requires new measures This is very exciting and it is great to see payment stepping into the 21st century, thanks to Apple
