Marvel AR (with AR standing for Augmented Reality) is a digital application from Marvel Entertainment created since the Marvel NOW! initiative, to allow the reader to have a more interactive experience while reading their comic books.
The application can be accessed through various comic books, if said books include a small AR banner in any of the pages. The banner is then scanned and immediately gives you access to bonus material related to the book. Said bonus material comes often if not all of the times in the form of a Youtube video that either provides a recap or exclusive content related in some manner to the book you are reading at the time.
