The patent is for tech that will match individual game discs to user accounts, blocking gameplay for games that have already been played on another user's account.
Each disc will have a contactless tag that can be read by the console, similar to NFC/RFID.
It is clear that Sony wants to eliminate the used game market, where it doesn't see a cent.
"As a result [of the patented idea], the dealing of electronic content in second-hand markets is suppressed, which in turn supports the redistribution of part of proceeds from sales of the electronic content to the developers."
