A couple years ago we were on a family trip and on our way back from Nagoya there was an electrical problem affecting all of the Tokaido Shinkansen. Because we bought the tickets with Smart Ex it was (relatively) easy to change to (much) later tickets but people with paper tickets were lined up all the way outside the station. Then, we knew we were entitled to a partial refund because of the delay but before we even attempted to ask for it the refund was delivered electronically. As you wrote, we have had problems with it not accepting some credit cards though.
That's pretty cool! My favourite thing is using my IC card to pass through the gates, though strangely, a few times it hasn't worked at all and I had to get staff to check my card.
