The patent explains that games will come with contactless tags that will be read by your console in much the same way as modern bank cards. When a disc is first used, the disc ID and player ID will be stored on the tag. Every time the disc is used in future, the tag will check if the two IDs match up and, if not, then the disc wont work.
