The story
The Digital Agency has announced which Android smartphones support the My Number Card’s digital ID functions on-device. The “attribute certification feature,” which can stand in for physically showing ID, is limited to select Pixel and Motorola models, prompting questions on the forum like “why is the Pixel 7 the only one excluded?” along with technical discussion about differences in the secure-element hardware used for authentication. Some pointed out that the iPhone already supports an equivalent feature.

What people said
Even the Japan-market version of that phone is based on the global spec, right?
These My Number-related features use some area of FeliCa's security zone, so I thought it only worked on phones that support Osaifu Keitai (FeliCa-based mobile wallet).
Oh, so this time it's a whole new method?
Then maybe the guy from Re: #8 has a shot after all.

Lol, the 7 is literally the only one missing.
The news site's list is incomplete, so you should check the official info instead. Pixel's been supported since the 6.

Wow, that's a rare one you've got there.
The physical card, sure — but on the phone side it's like Re: #32 said.
They say that merging the My Number Card and driver's license into one is a problem if you lose it — you'd have no other ID left, so you'd end up shuttling back and forth between the police station and city hall, a real hassle. I wonder how that plays out once it's on a phone instead.

Why is the 7 the only one left out?
Maybe they just forgot to list it since it shares the same chip as the 7a?
It's probably just missing from the article's writeup — the 7 is likely supported too. I'd bet every Pixel from the 6 onward is covered. ★

Buying straight from the Android maker itself is a safe bet.

Well, Android's the only one actually made in Japan, though.
It's on you if something goes wrong ( ˘ω˘)

What, the 60 Pro doesn't make the cut!?

*Note: they only list models they've actually bench-tested, so in practice it probably works fine — as long as it has FeliCa.
(For what it's worth, I'm already using the phone-based My Number health insurance card.)
Oh, so it uses the FeliCa SE — that's why it's limited to FeliCa-compatible phones.
Ah right, the secure element.
Apparently Osaifu Keitai and Mobile Suica work by putting an applet in there, and the My Number stuff is supposedly the same deal. Not totally sure though.
So apparently you need a FeliCa-compatible phone from after a certain point.
But then why is the Pixel 7 the odd one out?
Just get an iPhone instead — even the cheapest current model handles it fine.
This feature is Android-only though, isn't it?
To begin with, current iPhone models can already use an equivalent feature. Get in the habit of checking before you shoot something down.
iPhone got a big head start on this — Android's only just now catching up.
This is confusing. The "electronic certificate" is the thing tied to that 6-plus-digit My Number password, while the "attribute certification feature" is basically the app version of the My Number Card itself. So having the attribute certification feature means you skip the hassle of tapping your card or entering a password on things like Mynaportal.
I wouldn't be inconvenienced even without this.
Logging into Mynaportal or pulling a residency certificate at a convenience store is handled by the electronic certificate (and that's already possible today, for that matter). The attribute certification feature, as I understand it, lets you present ID (via IC-chip reading) or verify your identity in an app without needing the physical My Number Card.
The catch is it's a whitelist system: it only works once the Digital Agency's database is updated to include your model, so if it's not on the list, you're out of luck.
So they dropped the FeliCa-only restriction and moved to a global standard. If manufacturers submit test results and the Digital Agency approves and adds the model to the list, then in theory almost any Android 9-or-later device could work.
Background and Key Points of This Discussion
Putting the My Number Card on a smartphone involves two separate features: the “electronic certificate,” used for things like logging into Mynaportal, and the “attribute certification feature,” which lets you skip carrying the physical card when presenting ID. The list published this time covers the latter. As posters on the forum noted, the older Android electronic certificate relied on FeliCa’s secure element, which limited it to FeliCa-compatible phones — but the new attribute certification feature switches to Google’s StrongBox, making it technically possible to broaden support to more devices. In practice, though, which models actually qualify still comes down to a whitelist system, where manufacturers must submit test results to the Digital Agency for each device to get registered. That’s likely why a phone like the Pixel 7 is missing from the list — not a technical limitation, but simply a registration process that hasn’t caught up yet.
