I haven’t noticed any delay in london with a card, phone might be 200ms slower than credit catd. I Haven’t been to japan for a decade, are they really that much faster - and does it make a difference? What happens if a card is wrong/doesn’t scan/is invalid/etc at the higher speed?
Japan's IC cards are weird and wonderful

#12If I had to ask “why is it so fast?” I’d turn it around and ask “Why are western systems so slow?” and posit that Western capital has an ideology that throughout matters by latency doesn’t. (As Fred Brooks puts it, “Nine women can have a baby in one month”). As an individual or a customer you perceive latency directly though, and throughout secondarily. So it comes down to empathy or lack thereof.
Governments who think this set speed limits on roads to 45 mph, since that's the speed where most cars pass per second on a busy road.
Those same governments then act all surprised when it turns out their whole population is depressed and overworked when they work a 9 hour workday, commute 1.5 hours each way, and have no free time for life, relationships, hobbies, etc.

#13I could use my European smartphone (well, smartwatch) as an IC card in Japan. I don't think it was slower.

#14Now it's a fiddle with an app, then try to get the right angle on a smudgy reader. Getting onboard takes much longer and it feels like technology sent us 2 steps back instead of forward.
IC cards are better, and if they could be integrated in the phone then it would be even better and faster for everyone.

Paris adopted an IC system as well and it is pretty usable, but not pushed to the extremes of the JR system because they weren't ready to invest as much, manage the money aspect and really make it a full blown business.
[0] some lines and areas are definitely money pits. That's where some companies bail out of the IC system altogether for instance, or go with a different, incompatible but cheaper implementation.

#17I love IC cards. They had them on all transport where I live, but a few years ago they changed to QR codes.. Now it's a fiddle with an app, then try to get the right angle on a smudgy reader. Getting onboard takes much longer and it feels like technology sent us 2 steps back instead of forward.

#19Earlier quoted context omitted.
The magnitude to which FeliCa was faster shocked me as well when I found out. But it's not like the latency is insignificant: it's obvious how much faster people can get through a Tokyo metro gate than a London one. So clearly it must have some kind of financial impact as well, if an entire city's public transport system works slower because of it. Even ignoring empathy for a second, isn't this the kind of thing that…
The departure times dominate latency and throughput in metros. The gates are not the bottleneck.
Here's an example video to show the gates in action: https://www.youtube.com/watch?v=YffjxN3KsD4

#20Unfortunately transit operators are looking to discontinue the use of these IC cards in favour of QR codes as part of a cost saving strategy: https://mainichi.jp/english/articles/20241015/p2a/00m/0bu/01...
>It will continue to accept national IC cards such as Suica and Icoca
