Easy how? AFAIK there's no API to read the biometric data from the secure enclave. The secure enclave will only validate if what the fingerprint sensor reads matches what it has stored internally for authentication.
Additionally they don’t store the actual fingerprint pattern, they do a hash off of the subepidermal layers of your skin.
You can’t compare that to inked fingerprints.
The device can do it, but someone needs to be told to change some of the software or hardware.
Legally very easy, technically not so much.
The EU requires you to attend a meeting to submit biometric data when you initially register.
That sounds like a bureaucratic issue and not a technical issue.
It very much so sounds like a technical issue.
I have no finger prints, worn away, I am far from unique. So, technically, I don't imagine it being that easy?
Then you could encounter a "computer says no" situation
