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.
Parenting would really be having a great role on making your children able to avoid those things but we know that not all children would be that obedient nor do follow everytime on what their parent tells them.
For government actions about blocking it then this is a very common step that they would really be making even though it might not really that 100% effective but at least they could lessen out
with those minor involvement with gambling which is something not really a bad move or action that they had made at least.The rest of these things would be talking about
on some parenting which would really differ on each parents on how they would really be doing or handling it.
