User interface tag for use in processing a document

摘要

A user interface tag for use in processing a document is provided. A printable surface is on one side of a document and an adhesive surface is on an other side of the document. The printable surface further includes a printed data field, including machine-readable marks of digital data encoding a service and a user identity; and a printed border surrounding the printed data field to define an iconic representation. A scanned representation of the machine-readable marks is decoded from the iconic representation to specify the user identity and the service.
