So I just got reminded about google being shitheads again: Specifically over the gpay HCE transit card functionality.

Specifically, they're gaslighting people in official support channels who are wondering why they can't add a Japanese transit card to a non-Japanese pixel, by claiming "The non-japan SKUs don't have the FeliCa chip." Except that statement is utter horseshit: there is no separate FeliCa chip. All that stuff is handled by the combo SE/NFC controller, which wouldn't you know, is exactly the same model across all SKUs and fully supports NFC-F and Mobile FeliCa. If anyone has an NFC-F reader (or a proxmark) and a Pixel, you can verify this by reading the IDm from it.

For absolute proof that the restriction is totally arbitrary, you can either modify a single line in a config file, or SKU-swap to a japan SKU, and wouldn't you know it, it fucking works just fine: https://github.com/kormax/osaifu-keitai-google-pixel

Also, bonus bullshit: they disable mifare-based cards like SmarTrip in gpay on japan SKUs.

For context, every iPhone can use every transit card. US iPhones can use Suica et al. and JP iPhones can use SmarTrip cards without any problem, because apple hasn't added a completely arbitrary us-vs-them to presumably cheap-out on the licensing fees. I suspect that if google had wanted to support the feature (rather than what current evidence suggests, of "begrudgingly accept while complacently waiting for visa to crush everyone else under their monopoly") they could have negotiated "only pay the fee on devices that activate it" because it requires an external server to provision the card in the first place, so they know of every activation.

(also, a quick tip for the above-mentioned config bypass: FeliCa cards do not get erased by a factory reset, while mifare-based ones do, so you can get "the best of both worlds" by rooting, provisioning all the JP cards you want via osaifu-keitai directly, and then flashing back to stock and locking the bootloader)
