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?
Usually KYC involves selfie holding the ID so it's impossible to use this trick on stricter law imposed by the government. I doubt that the German government didn't think about this carefully by just requiring ID to verify the account. There might be some extra layer of security besides selfie to make sure minors will be filtered properly.
I agree, there's nothing I can think better that this way. It is very hard to monitor online transactions especially that we know this is still in crypto. If they will try to access mic or camera it will go against the privacy rule, family needs to monitor their child as well. Kyc is only way, but not all people like that and there's no exemption whether you are a minor or adult you still need to do it.
