Ah, Windows Biometrics
I bet the powers that be are all very excited.
One of the core features about Windows 10, strictly keeping all biometric data on the user hardware. I guess what Microsoft has done (and its based on old technology) is to use MS Passport as a link to the hardware ID and Biometric ID sensor hardware device(s) to replace software based passwords. Access to a user's Windows 10 system will require authenticated via biometric sensor, once confirmed the computer is ready... from there on logins to sites will be authenticated instantly, no need to remember passwords. This also means that in the near future software installs will also be instantly authenticated, just run the install... Done (a computer voice will say: Your install, registration and activation is successfully completed)!
This ties in with what I have read about the RFID Chip, the size of a grain of rice that will be implanted in the hand. This chip will carry a unique ID number, so simplistic because that ID is basically all that's required to authenticate access to all services transactions and reports such as, credit, medical, criminal, retail/marketing, Internet activity and downloads. These chips can also be used for location tracking to catch criminals and to help protect the most vulnerable in society such as kids and invalids (i.e medical alert)!
