Abstract
Examples to prevent the return of a printed medium and to authorize access to supplemental material to a printed medium upon resale of the printed medium are described. An example method of preventing the return of a printed medium including a product identification code and a unique identification code includes verifying the authenticity of the unique identification code against a database of genuine unique identification codes. The product identification code identifies a type of printed medium, and the unique identification code is associated with the printed medium and not associated with other printed media having the same product identification code. The example method also includes providing a clearance status based on the verification, which authorizes the return of the printed medium when the unique identification code is valid and denies the return of the printed medium when the unique identification code is invalid.
