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.
Most of the time, restrictions will give these minors a rebellious mood.
So yes, it is better to educate them and be open for discussions about this topic.
Because the more you restrict them, the more they have the nosiness to try the game.
If the parents will set a good example, the kids will have the notion that they need to follow also their parents.
Bottomline, it is how you instill discipline and good disposition in life to these young minds.
In time, they will understand the significance of what your are conveying to them.
