In a blog post Richell notes that the New York version as far worse since it “explicitly forbids self-reporting and leaves the allowed methods to regulations written by the Attorney General” and so developers of operating systems and devices would have to have more than just your date of birth to put you into some age bracket like the California law seems to allow.
These types of laws seem to be popping up around the US. How long until this plague spreads to other countries?
That is kinda the point of the California one. The parents identify the device as belonging to a child when setting it up. There is no verification past asking for a date. The Illinois law also appears to be constructed in this way (I may have missed something though). The New York and Texas ones seem to require ID though the wording is vague. Utah and Louisiana outright require verification. Interestingly Louisiana’s law explicitly considers children married under 18 not to be minors for the purposes of the law.
