This is of course cut to only show failures. But, e.g., in Boston, the MBTA uses RFID cards. One big benefit is that I don't have to take the card out of my wallet: I only need to pull the wallet out of my pocket, and tap the entire thing against the sensor — it can read the card through the wallet.
I'd wager it's easier than that swipe. Probably lasts longer, as there isn't any physical contact.
(Now, the MBTA also still has a paper-card variant, and that isn't RFID: you have to feed the card through the machine. Tourists might encounter that, but the locals use RFID cards.)
Similarly, Caltrain in the Bay Area uses similar cards. (Not quite as nice, though, to reload…)
