However oyster really is in its way out for most uses. contactless and especially a phone is far more convenient for non season use, and far less wasteful.
The only ones that I came across that are not Mifare, and not even readable by Android (but readable by the Flipper Zero), are the paper tickets used in Brussels. Then, of course, there are non-NFC tickets. For example those that use magnetic stripes, like the cute tiny ones in Paris or NYC's MetroCard.
There are two distinct types of Oyster card, but I don't know which is which, other than from a user perspective. All I know is that I had an old style one (the one without the white D in a blue square on the back) and you could still use it, you just couldn't "connect it" to the app so you couldn't look up your travel history.
There was a complicated process for returning it and getting a replacement, but as they'd already phased in paying by bank card by then, and the only advantage of an oyster card was for season tickets, I just returned it and got my deposit back.
But if you're into collecting different card types, you might want to try to get hold of one of these old ones as well. They're probably somewhat rare now, as they were encouraging people to upgrade to the new ones at least 5 years ago.
It's conceptually very similar to MIFARE – a fixed function IC implementing a fully offline stored value purse – but uses a stack that differs from ISO 14443 A on pretty much all layers. (It was planned to possibly become ISO 14443 C, but that never happened.)
Yes: Felica was developed by Sony in Japan, but was actually first adopted in Hong Kong, then later in Japan. It's far better than other standards, because it's so fast.
I'm looking forward to not having to choose one trade-off over the other.
Here's a good summary of NFC protocols used for transit gates: https://atadistance.net/2020/06/13/transit-gate-evolution-wh...
The Felica standard is fastest at 100ms per tap, and is used in Japan (e.g. Suica card) and Hong Kong (Octopus card).

You don't have to unlock your phone -- just tap. If you have an Apple watch, just put your wrist to the reader.
I use this all the time in NYC and it's so fast.
It’s still fast enough that it will read my Apple Watch before the gate starts to close from the passenger in front of me.
One saved trip to an Oyster top-up machine will make up for a lifetime of contactless NFC latency!
Wrong. With the traffic volumes normally seen in Tokyo, those few hundred extra milliseconds will cause huge delays at the fare gates. There's a reason the systems here use the Felica card which processes in 100ms: it's really needed for this kind of pedestrian volume.
In Japan credit card transactions routinely take a couple seconds. Imagine each person taking 5 seconds to go through the gate! I think what trials for credit card payments in transportation services there are doing is simply not processing the transaction inline, and just doing it after the fact (assuming it will go through).
If you try to use a card that is valid but has no available balance/credit, it might work for the first ride but then be blocked when you try to use it for the return trip.
Fares are batched throughout the day and you are charged once, overnight, for all rides that day (after applying any multi-ride discounts, etc).
This is different from some other cities where I’ve used contactless payments and they’d charge you immediately for each ride, giving you lots of annoying little charges on your bank statement!
Don't ask me how though
The Japanese transit cards that are supported by Apple Pay have that option, and it's arguably the best of both worlds.
It is, there’s even an auto top-up option that adds credit automatically if your balance drops below a certain level.
But there’s no “digital” Oyster card, only physical ones. If you want to use a device to pay you have to use contactless.
And either way, it’s still kind of a pain to have to maintain a balance - especially if you’re a tourist or visitor and don’t know exactly how much credit you’re going to need.
I agree that being able to load a transit card into Apple Pay etc is also a good solution. The convenience of not having a physical card that can be easily lost or forgotten is probably the biggest benefit for me.
Octopus (used in Hong Kong) is the one that supports virtual cards in Apple Wallet.
