The Matrix Barcode Family: Formats, Uses and Free Generation
Matrix codes store data as a grid of modules read by camera rather than a sweeping laser. They carry hundreds to thousands of characters plus Reed–Solomon error correction, so a scratched, partially covered or poorly printed symbol still decodes — the property that put 2D codes on everything from factory floors to restaurant tables.
QR Code dominates consumer use; Data Matrix rules direct part marking and regulated healthcare packaging; Aztec rides boarding passes and tickets; Micro QR, rMQR and Code One squeeze into tiny footprints; Han Xin and Grid Matrix serve Chinese national standards; UPNQR encodes Slovenian payment slips and Royal Mail 2D Mailmark carries postal tracking data.
