Abstract: A mobile device is used as an input/output device for a player tracking system for gaming machines, such as slot machines. Each gaming machine has a unique identifier and each player has a unique identifier that is associated with an account of the player. Player credentials are electronically communicated via the mobile device directly to the player tracking system, and each player credential is associated with a player's unique identifier that is maintained by the player tracking system. The mobile device is also used to electronically communicate directly to the player tracking system a gaming machine that the player wishes to play. Prior to initiation of game play on a gaming machine, the player tracking system associates the unique identifier of a player with the unique identifier of a gaming machine that the player wishes to play.
