Systems and methods for using machine readable codes to store and retrieve reversible write eraseable paper documents |
摘要 |
An embodiment generally relates to systems and methods for electronically auto-filing and retrieving erasable paper document documents configured for ultraviolet (UV) imaging. A device can embed a machine readable code on an erasable paper document, or can detect a machine readable code preprinted on the document. An electronic version of the erasable paper document along with the machine readable code can be stored in a database. When the machine readable code is later detected on a rendered document, the electronic version corresponding to the machine readable code can be retrieved from storage. The erasable paper document can be re-rendered using the retrieved electronic version either as a new erasable paper document, for display to the user, or other renderings. |

1. A method of accessing documents, the method 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. |
