You do not "deposit" money for your play at any casino.
You take out a "line of credit" which, obviously, is checked by the casino credit staff which includes, but is not limited to, a current bank account, your credit rating, etc.
Most people that have a line of credit will either pay off their "markers" with cash or check before they depart, or will have it automatically deducted from their checking account.
Usually they give you a two to three week pass.
Just make sure you have enough money to pay it off.
They generally don't break kneecaps in the back rooms anymore, but you could be looking at some serious court time and/or jail time.
Casinos could not be more serious about their money.
P.S A "marker" is the equivalent of a check that you promise to pay back the casino.
