When I do not have to opt-out, I keep my wallet in back pocket, along with my passport or other type of ID I am using (NEXUS, pp card)
If I have to opt-out of the Chertoff Cancer Box™, I will put everything in my pockets into one of my carry-on's, and lock that section.
Have not had any problems, yet. During my first opt-out, I just tossed my wallet on top of my bin when I was about the get groped, and nothing happened to it.
