Right that's the system now where you send your id to the site. With the if app they won't know anything else than that the unknown person was over 18.
How? Now people are sending their photo ids to many sites. With the app you'd be sending a cryptographic key that tells the site nothing else than the person who has this, is 18+
Where I live a lot of kids have bank accounts, but of course it would be silly to put a lot of money there. But can't you deposit cash into bitcoin things and use them for payments or gift cards? I've seen those on some gambling sites.
And if you say “well they can steal their parent’s credit card,” how would that not equally apply to a parent’s photo ID or anything else necessary for age-verification?
Photo ID apparently needs a face scan too, it's not enough to just have the ID. Then you get into what if they steal the ID, fool their parents and whatnot which... I don't think that's as much of a concern tbh
I'm against sending pictures of your card. Just showing your card to a shopkeeper, that's fine imo.
I don't think there being a delay once you originally setup the app is a big issue or takes more than a few minutes max. You do that first time and then your phone is generating the key based on the master key, the site confirms the key with the central server. That sort of handshake or what it is called happens almost instantly.
Slightly better is still better, but imo a site knowing just an age range (18+) of someone they don't know compared to them having a picture of my id with all my info (name, dob, social security number, face, all that) is a lot, a lot better imo
I'd be more worried if the apps were closed source but the ones I've heard about that are making an actual implementation of the protocol are open source so you can see everything it is doing, who it is contacting etc
