I can attest that its also effective since we are using it too in our company every time there is a need for fast verification. However, even if that technology is very advanced and can eventually pinpoint if you are faking your identity or not, that does not guarantee that it can never be scammed by brilliant minds of minors. Technology should also know that. So for me, its really hard to control the minors these days not to gamble, unless if the parents will take the first step to protect their teens not to gamble.
At the home, the emphasis should not be on restrictions but on education about gambling, we have a saying that the more you restrict the more they will go for it because of curiosity, so parents should expose their children to gambling as a way to educate them but not to tempt them to gamble, children will listen if those telling them are their parents and about the truth of the subject.
