Abstract

Electronic trading cards are composed of a plurality of individual trading card files encoded on a single data storage device such as a computer diskette or laser disk, each with an associated deciphering key code for deciphering encrypted data in the individual trading card files, and each with a file transfer code which allows individual trading card files to be transferred from one collector to another, without the transferring collector retaining a copy for his or her own use after a transfer is made. The electronic trading cards are organized and viewed using an electronic binder that provides full featured database functions such as sorting, graphic presentation, and the like. The electronic binder tracks the number of identical electronic trading card files possessed by a collector such that he or she will be aware that duplicates or triplicates are available. The electronic binder also has provisions for updatable guides which can provide card valuation and prediction information. Suppliers of the electronic trading cards will select a plurality of individual files for recordation on a data storage device from a very large pool of files assembled by the supplier. The data storage device will include a copy protection code which allows the files on the data storage device to be copied a fixed number of times (i.e., once or twice is preferable). A specific example of electronic trading cards contemplated are electronic baseball cards.
