摘要:
A video game or other amusement/entertainment device has a card reader that can be used to establish game play credits. The reader can also be used as an input device to communicate control codes to the game or other amusement/entertainment device control unit. The control codes can direct the control unit to switch from a normal game play or other amusement/entertainment mode to at least one alternate mode for special promotions, tournaments or the like. Alternately, the control codes can cause the game or other amusement/entertainment machine to enter maintenance or administrative modes.
