If these laws move forward (and I don’t think they should), there needs to be a way to authenticate as over 18 without sending picture of your ID off to random 3rd parties, or giving actual personal details. I don’t want to give this data, and websites shouldn’t want to shoulder the responsibility for it.
It seems like this could work much like Apple Pay, just without the payment. A prompt comes up, I use some biometric authentication on my phone, and it sends a signal to the browser that I’m 18+. Apple has been adding state IDs into the Wallet, this seems like it could fall right in line. The same thing could be used for buying alcohol at U-Scan checkout.
People should also be able to set their browser/computer to auto-send this for single-user devices, where it is all transparent to the user. I don’t have kids and no one else’s uses my devices. Why should I need to jump through hoops?
