Techniques are described for reselling digital data content, such as books, other types of documents, music, video, software and games. Such data are stored in a small portable digital rights management (DRM) device, such as a non-volatile memory card or flash drive, along with a license that defines the extent of the use permitted of the data. The content and license data are processed by a microprocessor that is included in the memory card or flash drive, including modification of the license in response to the data content being resold and transferred to another memory card or flash drive. The process is a digital version of selling a book, CD, DVD or the like in a second-hand market.
