A two-dimensional barcode encodes data in a pattern across two dimensions rather than only parallel bars. This allows comparatively large amounts of information in a small area. GS1 uses different 2D symbols for different applications.[1]
Establish the required data and reading equipment first. A visible QR pattern does not establish that it contains a valid product identifier or traceability record. Test both the encoded content and its handling by receiving systems: extra label data helps only when it is interpreted correctly.
