Don’t call it age verification. Call it centralised personal data collection. And understand that it serves surveillance, not safety for children. Thank you for your cooperation.
@jwildeboer as far as I've seen so far, the only acceptable method for age verification is via an "older than X" attribute in the open source Yivi (previously IRMA) identity wallet, excluding additional identifying data.

@joepbc @jwildeboer

Exactly .. With those kind of identifiers it is very well possible to keep the real data secure in a few vaults.
In NL banks have iDin. In a way similar. There are more solutions possible to use.
