How does an online casino verify a player's age?


The title speaks for itself ...
I found information that age verification is "usually be done behind the scenes by a cross check against the electoral role when you sign up" and that casino "use various automated database checks".
Can you please clearly explain what this means? Thank you for your willingness.
You answered your own question yourself lol.

That is all they will tell you. Even if you ask live chat at that casino. They will just say a vague line like you said. They also do a soft search on your credit file as well!
