Abstract
A method for graphically representing binary data in a condensed, machine-readable form, includes forming a pattern of information-carrying frame and synchronization lines defining a geometric reference system which forms boundaries of one or more data fields. The reference system carries machine-readable marks such as a bar code identifying the pattern as a data-field reference system and providing orientation and other information. The reference system also includes synchronization lines forming boundaries of each data field and providing a location reference. Within the reference system the data field has dot locations functioning as data-transmission elements. Each location has or lacks a mark, representing a '1' or '0' binary bit. Each data element location has a known geometric relationship to the synchronization lines of the reference system so that coordinates of each individual mark can be determined precisely.
