The only way for every single person to be on that system would be if there was a national card of some sort, and that just isn’t going to happen. (though there are some interesting sci-fi stories about it).

Credit card companies and banks are the ones on the fore-front of this movement now, so for low-middle class and higher, using plastic instead of paper is already a reality, but for anyone in the lowest classes of our society, it is an impossibility. which is why I said a national think would have to be done before the paper money was "put away."

I think that will be a very long time in coming. Especially with the sentiments about how things are even now.
