Yet another reason why DRM is wrong. When a Barnes & Noble customer tried to download a previously paid-for book, an error message appeared, stating that the download had failed because the credit card on file had expired. As the cool kids say, “Epic fail.” The expiration status of a credit card for a previously purchased book should be entirely irrelevant for a later download, and to extend the scenario, there should be no requirement that the account be linked to a credit card at all after the purchase has been completed. follow link
