That's for card emulation. This article is about using iOS devices as readers.
ISO 14443 card reader functionality has been made available some iOS versions before, but it's still restricted (e.g. you can't select any "payment" ISO 7816 applications, you have to predefine the list of AIDs you want to be able to select, and you don't have lower layer access to ISO 14443).
I'm not aware of any announcements to further open up "reader" mode.
Big companies that can afford to pay the certification fees maybe can; I definitely can’t. The entitlement is not available to regular app developers, unfortunately.
In the EU, maybe. And even then you will most likely need to beg for an "entitlement" to use it which may have requirements around being a registered business, etc so hobby apps are still excluded.
There's two versions of access to "card emulation" mode:
- The EEA-only HCE (which lets you emulate the card in your app in software, for a limited list of use cases, which makes it a non-starter for fully offline systems unfortunately, as there's no protection against exfiltrating any keys from the app), and
- The some-non-EEA-countries-only "full smartcard access" solution, which requires you to pay Apple and do a ton of (presumably also very expensive) certification.
So for different reasons, neither is something in scope for hobbyists at the moment, unfortunately.
