If you haven’t experienced suica, it’s like magically fast. Faster than NFC, faster than Apple Pay, faster than tap to pay, faster than Disney magic bands, faster than your work badge. It absolutely floored me every time I used it in Japan and it’s a full payment transaction.
But you should probably just get a suica in your apple or google wallet, you don’t actually need an IC card. I’m not sure if using a phone makes it less fast though, I couldn’t tell (we had to get a card for my kid since he doesn’t have a phone).
Definitely better than the QR codes used by China.
Same deal with Opal in Sydney - the old school opal card processes a second or so faster than a card/apple pay/google pay that you can just keep walking. Smashed into the barrier the one time I forgot my card.
That was not my experience in Japan; I found that it still took a second to go through every time, just like in New York/etc.
+1 you can walk through the subway turnstile and not slow down.
The card might be fast but getting one as a tourist is kind of a hassle
It's not only magically fast, but it's super useful. You can use it at vending machines + convenience stores anywhere (unless it's one of those old ones that only take cash/coins and print paper tickets) and at the shops as well.
People not in Japan/Singapore/Korea/China should experience what a proper transit card done looks like.
