So the minors are smart enough to fake their online identity? Really? This seems suspicious to me.
So they use their parent's debit/credit cards to gamble? Can't their parents view the transactions on their bank accounts? Can't they reverse unauthorized credit card transactions? If your kid is using your credit card to gamble, you are a lousy parent.
OP didn't stated that minors use their parent's credit cards to fund their gambling habit. He said that minors use their parent's account for them to gamble. If this is really true, how come these parents didn't notice anything on the gambling history of their account. Even if their children use other way to fund their gambling account, they will surely notice if someone use their account other than them.
But I still wonder if this kind of technology is effective enough for those minors who use their parent's access accounts to gambling sites. Will this be able to detect such action? Will this kind of technology can trully protect minors and prevent them to access gambling sites?
This won't protect minors but will only promote the unregulated casino or websites. Not everyone want their identity to be fully expose on the government, if they still have choice to not comply to these rules then they would surely prefer those that doesn't need that kind of verification.
