I think you are conflating many different things here. NFC-F is widespread. It's not a Japanese thing anymore. Also, the difference in latency between NFC-F based IC cards, and lower end NFC cards, is perhaps 100ms to 200ms, tops. You seem to think that Suica cards make a huge difference by comparing London and Tokyo flows of traffic, but London underground stations are older, narrower, and less modernized than those in Tokyo. Most stations in London are several decades older than those in Tokyo, poorly maintained, with a handful of gates for hundreds of people coming out at once. It's worth noting that latest Oyster cards are actually based on Mifare Desfire, meaning that they should be twice as fast as Felica cards on paper. On the other hand, why not compare other systems based on NFC-F, like those in Bangalore or Jakarta? Ignoring factors such as infrastructure, culture, prevalence of means of transportation, etc., and focus on one hundred milliseconds, is a bit myopic. |
