Abstract: A method for determining a bill mix in an electronic cash dispenser comprises: receiving a transaction request comprised of a transaction type and a dispense amount; evaluating the transaction type; evaluating the dispense amount; and determining the bill mix according to a dispense definition based on a plurality of criteria including transaction type and dispense amount. The method may further include evaluating day of the transaction request, time of the transaction request, patron information such as player tracking data, and/or bill inventory level. The method may also include receiving patron preference input. The dispense definition may comprise a minimum definition that defines a minimum quantity for each bill denomination to include in the bill mix. If a remainder exists after the minimum definition is applied to the dispense amount, the dispense definition may further comprises a remainder definition that calculates a remainder bill mix based on a least note methodology.
