House-banked card game licensees operating both house-banked and nonhouse-banked games may sell chips for poker games through an imprest bank other than the cashier's cage. "Imprest bank" means the bank must replenish funds on a regular basis to maintain exactly the amount of outgoing cash, chips, or coin (expenditures) minus the amount of funds added. The bank must be located within the cashier's cage or another location approved in the internal controls.
