<p>A computer-implemented method includes generating a plurality of playing cards, each playing card having a unique identifying code and one or more attributes; distributing the plurality of playing cards to a plurality of players, each player receiving at least one playing card; receiving electronic information relating to a playing card's unique identifying code from one or more of the players; and maintaining an online data registry relating to each trading card for which electronic information has been received. Maintaining the data registry may include tracking the one or more attributes (e.g., monetary value, strategic value, current owner) associated with each playing card. The data registry may be updated by modifying one or more attributes associated with a playing card in response to receiving information indicating a change in status of the card.</p> |
