And in an ideal world that would be no big deal. Indeed when I buy alcohol at the liquor store the cashier does a brief check of the ID and inputs the DOB in his terminal. There is a good precedent for using my ID to check my age. But I have no illusions of what would happen if we used it for online age check: the picture of the ID would be stored forever. The website would try to collect all the available info and not just the DOB (which includes full name and address as well as height and weight) and try to monetize it. And then of course there is a the risk of data leaks. So in our current world I am afraid that online ID checks are a hard no.
