change "A QR code (quick-response code)[1] is a type of two-dimensional matrix barcode, invented in 1994, by Japanese company Denso Wave for labelling automobile parts.[2][3] It features black squares on a white background with fiducial markers, readable by imaging devices like cameras, and processed using Reed–Solomon error correction until the image can be appropriately interpreted. The required data is then extracted from patterns that are present in both the horizontal and the vertical components of the QR image.[4]
Whereas a barcode is a machine-readable optical image that contains information specific to the labeled item, the QR code contains the data for a locator, an identifier, and web-tracking. To store data efficiently, QR codes use four standardized modes of encoding:
(1) numeric, (2) alphanumeric, (3) byte or binary, and (4) kanji.[5] Compared to standard UPC barcodes, the QR labeling system was applied beyond the automobile industry because of faster reading of the optical image and greater data-storage capacity in applications such as product tracking, item identification, time tracking, document management, and general marketing.[4]"

The QR code was invented in 1994 by Masahiro Hara, an engineer at Denso-Wave, to improve the traceability of parts in Toyota factories. Its fast scanning speed and robustness against damage, such as oil stains, made it an ideal solution for production lines. Released under a free license as early as 1999, the QR code was adopted in a wide variety of fields, far beyond the automotive industry.

Not done for now: The added paragraph overlaps with the above paragraph. It would be better to write one cohesive paragraph instead of two (or rewrite the two to avoid overlapping information). Ultraodan (talk) 14:40, 7 January 2025 (UTC)
