Casino markers are basically zero interest lines of credit issued by a casino to its players. The casino, however, requires the players/gamblers to allow repayment of the lines of credit by giving it access to the players’ bank accounts to pay off the money extended through the line of credit.
Since casinos are not in the business of giving away money, they expect to get paid back through the bank accounts of the players to whom they’ve extended credit. When this fails to happen because of insufficient funds in the bank account, then the casinos can pursue criminal charges. What you need to know is that obtaining a casino marker with insufficient funds in your bank account is the same as writing a bad check. It could land you in jail.
Under Nevada law, specifically NRS 205.130, unpaid casino markers are equally classified as writing a bad check. The state assumes you are guilty based upon an “intent to defraud” the casino because you built up an amount of money you allegedly knew your bank account would not be able to pay off. The penalties are equally the same as writing a bad check.
