It seems to me that in physical casinos it is absolutely impossible to get into the casino using someone else's documents, because the people at the entrance are not fools and they understand perfectly well who is in the photo and who is in front of them.
Maybe you can't use the other user documents, but you could use someone else bank account. In my country when you go to the casino they ask for a bank card, if you make a profit the money goes to that bank account, so, you could get a bank card from another person and use that to gamble, And it's similar to the online casinos, if you win big then they could ask for more documents but if you win small amounts there will not be any problem.
Casinos with professionals should be able to know that the bank card you are coming to gamble with isn't yours if actually they really paying any attention..
I mean, bank cards usually have the holders name imprinted on it, and such names usually match the document the holder used to open the account in the bank when it was opened.
So, professionals who are good at their job should know that when they ask for your bank card, they should also ask for your document, which as well must have your picture on it..
First is that - the name on the bank card must match the name on the document provided.
Second is that - the picture or image on the document provided must match the image of the person standing right in their front, if there is any form of descrepancies in any of this, it simply means that the gambler is not qualified to gamble but only forcing his way in.
And on the other hand, if there be difference in this documents but the staffs of the casino can't take notice of it, it simply means that they don't know how to do their job well.
