Uhh, if I am taking a plane trip, I am probably going to have my wallet with me, with passport too. I am referring to local travel.
As for carrying a license, it is not needed if the officer can pull your record up on his computer, which is what they do with a plastic license anyway. And you really believe people don't make fake copies of id's.?
As for ccw, every state is different. If I need to carry, I will look into the laws of the state. That is not an issue for many though. Just those that have twisted the 2nd amendment to fit their screwed up views. "Hey buba! Yeah Bobby Joe? You bring the ar-15 to go duck hunting?" seriously
Sorry to say this ( Not Really ) but you are wrong about just having a number and many other things too but I'll go with this for now.
When being pulled over and asked for your Drivers license and registration it means just that, and not what you think is sufficient in your mind.
Giving a cop your DL number does not proof anything to them or identifies you as being that person that that said number says you should be.
And will not be acceptable to them wether you like it or not.
Same goes if you go to a bar to have a drink if they ask to see your ID your number or a picture of it on a phone will not suffice to proof your age or your identity.
As far as taking your passport on a plane that all nice but a Drivers License will be needed in lieu of and you don't need a Passport for domestic flights.
And you do know that you can fly within cities and states in the US, you know it is still called local travel.
How you leaped from my example of a Concealed Handgun Permit which has to be accompanied with a DL or state ID in all states that offer one, to a AR15, Bubba and the Second Amendment of our constitution is beyond my comprehension.
But it paints a clear picture of what kind of person you are and are not.
This is all I will say about the constitution on this forum as it really has nothing to do with Google wallet or Pass books apps or phones and what you can and can not do with them.
I would like if you could do all that with those apps and would not need to carry both a phone and a wallet but it is just not doable at this time.
