Abstract

A machine-readable, human-readable coding system comprising a one piece, pre-printed label having at least two identical messages coded on the label. The label has two columns, one column, (2) being a series of aligned segments (6). There is one data character (12) of an OCR code located in each segment. The background of each segment is color coded for human readability. A second column (8) contains a single machine-readable bar code (12) containing the same message as the OCR code. The color coded segments and the OCR code are readable one direction and the bar code in the opposite direction.
