MVC3 at the arcades

I’ve watched several videos of arcades that are now gone and noticed MVC3 machines (I think Arcade Infinity and Chinatown Fair, correct me if I’m wrong). I’m curious if these machines were set up based on time, honor system, or what? Can someone enlighten me on how the game’s income was handled? Thanks in advance
