QRkood
QRkood is a term used in some discussions to denote a variant or proposed extension of two-dimensional barcodes modeled after the QR code. It is not a defined standard; there is no ISO/IEC specification labeled QRkood, and implementations vary. In general, QRkood refers to ideas for increasing data capacity, improving robustness, or adding optional security features while preserving a barcode-like format that can be scanned by image sensors. Because the term has no single specification, interpretations of QRkood differ among developers and researchers.
The concept emerged in the 2010s and 2020s in online forums, academic papers, and open-source projects as
QRkood variants typically resemble QR codes visually, with finder patterns and a grid of modules. Proposed
In speculative or experimental contexts, QRkood is discussed for packaging, ticketing, digital links, and authentication tasks.
