Candle device for providing transaction verification on a gaming machine

A method in a controller for a dual port touch screen (DPTS) display mechanically coupled to a cabinet of a wager-based gaming machine and communicatively coupled to a game controller disposed within the cabinet and a candle controller in a candle device externally mounted to the cabinet, the method comprising:

• receiving via a first port of the DPTS display video content for a wager-based game from the game controller;
• receiving via a second port of the DPTS display video content for an interface from the candle controller;
• receiving control commands from the candle controller for a size and a position of a first display window and for a size and a position of a second display window wherein first display window and the second display window don't overlap;
• receiving a resolution of video content for the wager-based game from the candle controller;
• outputting the video content for the wager-based game to the first display window and the video content for the interface to the second display window;
• receiving touch screen input data in the first display window;
• and
• based upon, the size of the first display window, the position of the first display window and the resolution of the video content for the wager-based game content, scaling the touch screen input data and sending the scaled touch screen input data to the game controller.

A method in a candle device including a candle controller and a plurality of lighting stages with internal lighting elements wherein the lighting stages are lit alone or in combination with other stages to convey information associated with a status of a wager-based gaming machine to which the candle device is externally mounted, the method comprising:

• receiving information associated with an electronic funds transfer from a bill validator wherein the information includes an account identifier;
• determining a size and a position of a first portion of the DPTS display for outputting the video content for the wager-based game without notifying the game controller of the size and the position;
• determining a size and a position of a second portion of the DPTS display for outputting first video content for a transaction verification interface wherein the first video content includes touch screen inputs for entering a PIN or a password related to the account identifier;
• sending commands from the candle controller for generating the size and the position of the first portion and the size and the position of the second portion to the DPTS display wherein the first portion and second portion don't overlap;
• sending the first video content to a second port of a dual port touch screen (DPTS) display wherein video content for a wager-based game is sent to a first port of the DPTS display by a game controller on the gaming machine;
• receiving touch screen input data from the DPTS display;
• determining verification information from the touch screen input data;
• sending a transaction verification request via a wireless communication interface to a remote device, the verification request including the transaction information and the verification information;
• sending second video content for the transaction verification interface to the second port wherein the second video content includes an outcome to the verification request received from the remote device.
