> People not in Japan/Singapore/Korea/China should experience what a proper transit card done looks like. In Prague city transit does not have limiting gates.

Maybe once a month (or even rarer) you might encounter a patrolling controller who would ask you to show your ticket, but that's it.
Makes for such a smooth journey as most people are doing the right thing.
