It's hardly an age verification if it just requires the bearer to have an adult's ID card.

You borrow your friend's card, or you "borrow" your parent's card, or you pay someone who sees this market opportunity.

I think it's ridiculous how the lawgivers are telling the companies to just nerd harder, but they're definitely going to have to nerd harder than that.

They know, of course, that they're giving the nerds an impossible challenge.

Then when they can't achieve it they can say, "well we tried the non-authoritarian way and the nerds didn't oblige, now we're forced to bring out the brownshirts. Papers please!"

I think it’s better than transmitting everything including the biometric picture and requiring the camera to be on.

How would you implement age verification?
