US Patent 10291796 Using labels in a document processing system

A document processing system uses a label on a document that includes a machine-readable portion that identifies a document, a first defined region corresponding to a system-defined function, and a second defined region corresponding to a user-defined function. When a user hand-writes a mark in the first defined region of the label, when the document is scanned, the mark is detected, and the system-defined function corresponding to the first defined function is performed for the document. When a user hand-writes a mark in the second defined region of the label, when the document is scanned, the mark is detected, and the user-defined function corresponding to the second defined region is performed for the document. The hand-written mark can include a character, with multiple system-defined functions corresponding to different characters in the first defined region, and multiple user-defined functions corresponding to different characters in the second defined region.
