a good idea (Score 0)

I think something like this is a good idea, but it has to be flawless. a system where anything you want can be paid for with one unit that you can also use to communicate with, that would make a lot of people's lives a lot easier. still, it must be excecuted perfectly, and then what about people having different models of cell phones? different services? it all goes back to the paradox of perfet execution.
