Xbox tests Disc-2-Digital: turning physical discs into digital licenses for cross-device play
Xbox is testing a Disc-2-Digital feature that lets players 'claim' a digital license from a physical Xbox disc on their account, enabling digital play on compatible consoles, PC, and handhelds while keeping the disc usable for lending or selling; the license is conditional and tied to the last user of the disc, and not all discs or games will be supported (no Xbox 360/OG titles, and some Xbox One discs may lack the required identifiers); the feature is in testing and not officially announced yet.
