They will have an app that asks to scan you passport with your phone's NFC reader. It's pretty common for Identity Verification.

Yeah was thinking the same thing. I wonder if the author didnt known that passpory chip == fingerprint.

And FP is a much worse modality to have registered because, as opposed to Face image, fingerprint is not affected by age. So that will match you 99.999999% for ever. Faces change.

Highly unlikely they did. Just because it’s in the privacy notice doesn’t mean they actually gather or store this information.

And indeed, fingerprints are only accessible using privileged access. Not even you, the passport holder, has access.
