MOBILE TRADING CARD GENERATION AND DISTRIBUTION

摘要

A computer-implemented method for generating and distributing electronic trading cards, such as for use with mobile devices, generates instances of electronic trading cards and distributes the instances to users over a computer network. A finite number of instances of each electronic trading card may be generated. Electronic trading card instances may include an image and a digital watermark. Each instance of an electronic trading card may have a unique identifier. One instance of an electronic trading card may include content that is not included on all other instances of the same card. A randomly-generated "pack" of cards may be purchased by and distributed to the user. The contents of the pack may not be made visible to the user until completion of the purchase. Users may purchase additional features, such as a guarantee that the user will not be provided with duplicate instances of any trading card.
