Patent ID: 8506387

Claim:
A gaming machine, comprising: a memory; an input device configured to receive a first currency value of a non-native currency type, the non-native currency type convertible into a native currency type and the native currency type being a type of currency used by the gaming machine for play of a wager-based game; one or more logic modules configured to: retrieve, from the memory, a first left-over amount that is a residual currency value of the non-native currency type from a previous currency conversion transaction that was not converted into the native currency type and that was not returned by the gaming machine, determine a total non-native currency value, the total non-native currency value including the first currency value and the first left-over amount, convert the total non-native currency value from the non-native currency type into the native currency type, thereby resulting in a total native currency value of the native currency type to use to play the wager-based game, the total native currency value being an amount of the total non-native currency value that was capable of being converted into the native currency type, determine whether there is an unconverted amount, the unconverted amount being an amount of the total non-native currency value that is not converted into the native currency type, and determine a returnable amount and a second left-over amount based on the unconverted amount, the second left-over amount being an amount of the non-native currency type that was not converted into the native currency type and that is not returned by the gaming machine; and an output device configured to provide the returnable amount.
