Am I miss remembering or can the nfc mobile train passes in Japan be used even with a dead battery?

Yes, I believe this is correct as the terminal you tap/place your card/phone near transits enough power wirelessly to read the NFC (F) data or so I have read. The NFC (Felica) + Osaifu-Keitai + Suica/Passmo system is quite interesting and super reliable. Source: on a train in Tokyo right now

Sounds like an iPhone feature: https://www.techradar.com/news/apples-iphone-xs-has-a-game-changing-nfc-feature-even-when-turned-off https://www.techradar.com/news/apples-iphone-xs-has-a-game-c... The Pasmo/Suica cards are intriguing, they are NFC, but also store the last few transactions on the card itself, there are also mobile apps for scanning these cards to see how much credit you have left and list the above-mentioned transactions.

  I’m a huge fan of the Pasmo/Suica cards. They’re easy to obtain and easy to accept payments, so uptake is huge (if memory serves me correctly, literally accepted everywhere?). You get most of the benefits of card payments (fast, no fiddling with change, no “do you have a smaller note”), but you also maintain anonymity which is a common argument I hear against cards in Germany and why card payments are so rare there (at least in 2017, I don’t know if the situation has changed).

    In Germany the pandemic had quite an impact. From 2019 to 2021 cash payments dropped by ~12%, down to 38% of transactions. What’s more important, loads of shops eg bakeries have card terminals now.

      Although the chances of formite transmission (i.e. through touch) is apparently quite low: https://www.cdc.gov/coronavirus/2019-ncov/more/science-and-research/surface-transmission.html https://www.cdc.gov/coronavirus/2019-ncov/more/science-and-r...

    They’re not quit accepted everywhere. Mostly in high convenience, small purchase places. You can get multiples of them for maximum privacy, but they’re 500yen each to purchase.

    Something like that (for general payments, not for public transport) used to exist in Germany ("Geldkarte"), but it never became a big success and is now being discontinued. And personally speaking – not being able to easily look up how much money is stored on that card is somewhat annoying, so I'd rather continue carrying cash in that case.

  My Japanese feature phone back in 2009 could also use Mobile Suica with a dead battery. I believe at the time the NFC wasn't active like on the iPhone but a passive "card" that was reprogrammed by the phone and didn't need power. The iPhone only got this "power reserve" recently.

  It was a feature all along since flip phones implementation, which was replicated and one-upped on iPhone. Phone implementations run from leftover charges on empty battery, not by power from the reader(which requires a coil).
