摘要：
The present invention is directed to game cards and systems for tracking game cards. A computer tracking system is used which includes game or lottery type cards which must be activated to be eligible for a particular game or event. The activation step includes reading of a unique serial number or other identification code uniquely identifying the card. With this system, surplus game cards can be disposed of when they have not been activated. This simplifies tracking of sales of game cards and simplifies the distribution of funds to various parties in the sale and distribution chain.
