MOBILE TRADING CARD REDEMPTION

摘要

A computer-implemented system distributes digital content (such as electronic trading cards) to users and receives such content back from the users. Consideration, such as rewards, may be provided to users in exchange for the digital content they return to the system. For example, a redemption program may provide a reward to users who redeem a specified group of electronic trading cards. Users may trade digital content with each other, and a user who returns a particular unit of digital content need not be the user to whom the digital content unit was originally distributed. Cards may be individually identifiable, enabling both the original recipient of a digital content unit and the redeeming user to be identified. Each user may use the system to keep track of the digital content units that the user has returned to the system so far.
