This seems like an interesting solution to me. Obviously we have gotten to a point where our computing power has rendered the kind of passwords that most people can easily remember and use fairly trivial for many password cracking methods, and so there is a clear need to develop a convenient method of using more complex methods of authentication. The idea of using a smartphone as a central area for things such as identification and payment(Google Wallet) has been something i've been interested in for a while, and something I think could be amazing if we manage to work out a few kinks that are in the way of making it a viable option. For this to become a reality i think there are 3 main things that would need to happen: 1) Battery life on smartphones would have to become a lot better, I don't want to have to worry about if I'm going to have enough battery at the end of the day to pay for dinner, get into my car, etc. 2)The ability to remotely clear data on a device that may have been stolen need to become a standard. 3)There need to be some sort of authentication between the user and the device in order to approve the use of stored authentication.
