It is the opinion of many who live in Illinois that a fanny-pack type holster with an unloaded pistol and loaded magazine, and possession of a FOID card meet the transporting and case requirements of the law. I have discussed this with a variety of law enforcement officers from several departments (all in Southern Illinois); many agree, others don't. Legal or not seems to depend on where you are and who you talk to. Not much to hang your hat on and not a recommendation, just throwing it out for discussion.
