Mine sits behind my DL with them back to back.
I can slip it from my wallet and if someone happens to see it they only see the back of it.
The only time I have ever been asked for a second form of ID I have just told them that I have to go home and get my passport, then ask, would a credit card work. Never had to go back home.
I don't want the clerk at the store to ask about it incase the guy behind me is the bad guy I may need to stop.
