At carnival in Bazil, you bump into people; Like, when they talk packed streets, they're talking body to body contact filling the street for blocks and blocks. All you'd have to do is put a terminal around your waist and you'd get close enough to activate NFC for hundreds of people just pushing through the crowd.
