Abstract: A game system is presented. The system includes a plurality of cards, each card being associated a game feature, and a scanner configured to scan information from the cards. The processor is operable to associate a first card with a first player upon the first player causing the first card to be scanned, associate the first card with a first game feature, display a representation of the first game feature on a first display area associated with the first player, enable the first player to access the first game feature, reassociate the first card with a second player upon the second player causing the first card to be scanned, display the representation of the first game feature on a second display area associated with the second player and enable the second player to access the first game feature.

Abstract: There is provided a game card, game card system, game card reader and method of authentication and fraud prevention. Machine-readable codes are provided on game cards. The code on a game card is read by a game card reader employing two code readers. One code reader uses visible light to read the code, or in the alternative to merely detect the presence of the code. The other code reader uses infrared to read the code. A fraudulent game card, copied or reproduced by photocopiers, scanners and digital cameras available to the general public, is detected based on the absence of a code reading from the second code reader. The presence of code information on a game card that is detectable using visible light, also indicates that the game card is not authentic.
