The tag agent gives you a paper license when applying for a real ID. Works for them.I would never mail my DL to anyone, make a copy of the front and back and send to them, because without it you wont be allow to drive so how you going to get around to go to work, get groceries and other personal things you need to do. I hope your not planning on sitting at home waiting for them to mail it back to you cause if you are your heirs may get it after your dead and gone.
If I did have to mail my DL in, I think I would take pics of both sides with the phone and store it in the library.
Ok hunting/fishing license used to require the original copy to be carried in the field. Now a pic works if I remember right and it is of both sides. I know most states we visit are doing that now as well.
