Well you wouldn't say "This person is clever" OR "This person is smart". Those don't sound right. You'd say "He's smart." or "He's a smart guy."
You could also use clever in those situations. Smart and clever are nearly interchangable. Both mean a person is intelligent. Clever however has connotations that one is good at figuring out things, rather than simply having book knowledge.
Smart means you know the capital of Zimbabwe is Harare.
Clever means you can figure out how to create a rocket-propelled flare out of bamboo, fertilizer, matches, a strip of cloth, a small tin can, a thin metal rod, a funnel, and a wooden spoon.
