A machine-readable visual marking consisting of parallel lines, spaces, or geometric patterns that encode alphanumeric data for automated interpretation. The pattern is standardized so that optical scanners can decode it back into structured information, enabling rapid identification and tracking of objects, products, and documents.

Definition
Why it is in scope
A human-made visual marking — parallel lines, spaces, or geometric patterns — designed to encode data for machine reading. Built for persistence through universal standardization in commerce, logistics, and inventory systems, where optical scanners decode the pattern back into structured information.

Test: symbol first, then barcode. A barcode is a specific kind of symbol — a machine-readable visual marking designed to encode data. A competent speaker would say 'a barcode is a visual symbol' — specifically one designed for automated reading. Files against nearest kind per Law 9.

A data matrix code is a specific kind of barcode: both are machine-readable optical labels that encode data in visual patterns. A competent speaker would call a data matrix code 'a type of barcode.' Per Law 9, specific→general. The direction is correct and the sense is clear: we're talking about the class of 2D/barcode symbologies.

A QR code is a specific kind of barcode: it encodes data in a machine-readable optical pattern of black modules on white background, designed for scanner interpretation. The 'finder patterns' in a QR code are a specialized variant of barcode symbol markers, and the ISO/IEC 18004 standard classifies it within the barcode family. A competent speaker readily says 'a QR code is a type of barcode.'
