Can you actually exit the system without scanning the card again?

  It depends on the system. Most Asian metro systems charge a fine-grained per-distance fare, so they require scanning on exit. Boston (and NYC I think?) is per-ride except for a couple stations that charge a surcharge to exit, so exiting doesn't require scanning except at those couple of stations.

    Boston eliminated the last of its subway exit fares years ago. (The system is famous for the song Charlie on the MTA, about a man trapped on the train due to an increase in the exit fare.) There are a couple of bus routes that require payment on exit. However, it's not a variable fare. It just works that way because the configuration at Harvard station requires entry on the left side side (without the farebox) and exiting curbside. So people pay as they leave, instead of when they board.
