This is very difficult for me because I hate having anything in my pockets. The answer is just to carry around a briefcase, I think. I really hate stuff in my pockets... I don't know, I'm weird. But, when I must: wallet in inner breast pocket, cell phone in right pants pocket, keys in left pants pocket, along with any other random stuff - pills, sore throat lozenge, etc. business card case in right jacket flap pocket And all the other million things I carry around just have to stay in my bag and don't get to come with me.
