QR Code Standards & Error Correction

Quick Response (QR) codes use Reed-Solomon error correction to reconstruct data even if parts of the barcode are smudged, obstructed, or printed on uneven surfaces. Level M (15%) is standard for web links, while Level H (30%) is best for logos or physical prints.
