Not to mention almost every place allowing you to pay using that card.In Asia, you could get these types of cards at any convenience store...and you could use the cards there...and you could recharge them there...and it literally took seconds to recharge...and the stations that took money for fares always worked...

They've had decades to work it out in Asia although you could also ask why it took so damn long for us in North America to catch on.
