Cringe. Cards are fun, collectable, and never run out of battery. Mine is a custom limited edition card from a Japanese chocolate factory. https://matcha-jp.com/en/9482

Suica cards (and transit express payments in other regions) work after iPhone batteries die for a few hours.

Are you saying that an iphone can be used as a Suica card even with a dead battery? Or just that a discrete card still works when your phone is dead?

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.

The card might be fast but getting one as a tourist is kind of a hassle

I heard from friends that physical Suica cards tend to be difficult to obtain these days at times, but digital one isn't at all.

Took me roughly a minute to create one within Apple Wallet ahead of my trip, and that was it. Didn't need to install any apps or register on any websites, because creating a Suica card is natively supported in the wallet app.

Idk how the situation is like with Suica card on Android though, outside of the fact that unless the phone was purchased in Japan, it will typically lack the necessary hardware for it (which isn't a concern with iPhones, because all regional versions include it).

Sad to see the mascot going in March. Apparently this entire brand reset is tied to something JR East is calling 'Suica Renaissance,' which is about a ten-year effort to turn Suica into a lifestyle brand. Whitepaper: https://www.jreast.co.jp/e/press/2024/pdf/20241210.pdf They're planning on moving beyond the ¥20,000 prepaid balance limit, they are adding QR code payments (think WeChat and Alipay), making Suica work a…

The weirdest payment method has got to be the Coke ON vending machines that do not support SUICA but instead require you to QR code-IR blaster you to a website where you bluetooth pair with the vending machine then buy it on your mobile browser. Like....somehow they turned a sub 1ms operation into a 4 minute 32 second one. It boggles the mind

Coke ON Pay uses an app that automatically pairs with the machine when you open it [1]. It’s pretty quick and takes less than 30 seconds once you set it up.

I think you might be referring to QR de Kessai [2], which was introduced in 2023 and is targeted more at inbound international tourists who don’t want to download the app and may not have an E-Money card. Basically they aim to support to support the widest possible audience - at the cost of a slow/clumsy experience. These machines should also accept payment via the faster Coke ON app method and often have E-Money tap-to-pay options too.

From that perspective it kinda sorta makes sense. But yeah I wouldn’t bother with it unless I was dying of thirst and I had no cash or other payment options available.

iPhones still let you use certain contactless features (like Suica) even when the battery has "run out" (ie., the main OS has shut off). The reserve battery power is enough to run Suica, CarKey support, and FindMy.

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.

You can use a digital Suica in Google Wallet only if your Android phone has Japan-spec hardware . International Android phones bought outside Japan generally cannot support digital Suica cards in Google Wallet.

Pixel phones bought outside Japan supposedly can if you do a little adb hacking to enable it, but I don't have a Pixel to try it myself.

Wait, the balance is stored on the card? I'm fairly sure the balance is shown in the JR app too, so presumably that cannot be the case. [Update: or maybe not? I opened the app now and it's asking me to enable NFC and hold it up to the card.] Anyway I love my Suica. I got it a good decade or more ago, I have a few thousand yen on there, and it's always ready for me when I go back to Japan. Useful on the Metro, trains…

The card definitely stores the balance. They probably sync the transaction records to their servers, but during the transaction the value on the card is presumed to be the truth AFAICT.

Remember when the system was designed in the early 2000s the Internet was much less available and reliable, and when so many transactions happen every day, you don't want to get thousands of passengers stuck inside a metro station only because some Wifi router was down.

This is basically a limitation of the CAP theorem, in these situations there's really no choice but to sacrifice "consistency" and settle for eventual consistency.

I think even credit card payments for transit also make that sacrifice. I had a weird experience using a Visa card to pay for a tram ride because they were promoting it and had a discount. The machine indicated success and let me through, but since I rarely used the card, somehow the payment didn't go through afterwards (the credit card was in a very weird state). If they insisted that all the payment transactions complete successfully for a transit payment, it would be too inconvenient and unreliable to use.

> The cards have no battery and aren’t self-powered in any way. Instead, the reader on the gate emits an electromagnetic field that powers the card just long enough to complete the transaction. Brillant!

Brillant! AT&T showed this in television commercials back in the 1980's. "Can you go through a toll booth without stopping? You will. And the company that will bring it to you is AT&T."

The 90s https://en.wikipedia.org/wiki/You_Will

Lots of those things happened (maybe not faxing from the beach), but AT&T didn't bring us very many of them.
