In functioning states, the ID contains a chip with a private key that can be used to sign a message, and ID verification would not be an image of the ID card, but rather holding your phone's NFC reader to the card and signing a message from the site.

In Japan, there are already multiple apps which use something like this to verify user's age via the "my number card" + the smartphone's NFC reader.

It's more or less impossible to forge without stealing the government's private keys, or infiltrating the government and issuing a fraudulent card.

Of course, the US isn't a functioning state, the people don't trust it with their identity and security and would rather simply give all their information to private companies instead.

Does this also leak your identity to the app?

There is not a way to share just your date of birth. After providing your PIN it can read more than just your date of birth.

		That's... partially true. If you use the _digital_ MyNa card (e.g. the one in the Wallet.app; not the plastic one); the iOS SDK lets you only request the "is user more than XX years old" flag; without getting the actual identity: https://developer.apple.com/documentation/passkit/requesting... Now, AFAICT nobody actually does this, but the technical ability is there.
