Systems and methods for using machine readable codes to store and retrieve reversible write eraseable paper documents

A system for accessing documents, the system comprising:

• a processor coupled to memory and configured to perform actions comprising:
• receiving a selection from a user that content to be printed is to printed on an erasable paper document;
• saving the content in a database for a fixed time period based on the receiving the selection;
• obtaining a machine readable code printed on a substrate of the erasable paper document, wherein the machine readable code uniquely identifies content to be rendered on the erasable paper document;
• determining that content that was previously rendered as transient content on the erasable paper document has faded;
• obtaining, on a server, an electronic version of the content based on the machine readable code based on the determining and additional value-added information to be rendered on the erasable paper document;
• causing, by the server, the electronic version to be displayed on a display that is viewable by the user, wherein the electronic version comprises information indicative of how a previous version of the erasable paper document was imaged;
• receiving a determination that the electronic version is approved for printing from the user;
• rendering the content and the additional value-added information based on the determination that was received that was obtained on the server as transient content on the erasable paper document;
• rendering a dynamic code on the erasable paper document, wherein the dynamic code comprises an indication of a storage location of the electronic version of the erasable paper document in the database, wherein the dynamic code comprises a code rendered in invisible ink that becomes readable when exposed to ultraviolet light;
• and
• deleting the electronic version of the content from the storage location after a predetermined amount of time.
