For example, the generator polynomial used for the Version 1 QR code (21×21), when 7 error correction bytes are used, is: g ( x ) = x 7 + α 87 x 6 + α 229 x 5 + α 146 x 4 + α 149 x 3 + α 238 x 2 + α 102 x + α 21 {\displaystyle g(x)=x^{7}+\alpha ^{87}x^{6}+\alpha ^{229}x^{5}+\alpha ^{146}x^{4}+\alpha ^{149}x^{3}+\alpha ^{238}x^{2}+\alpha ...

High Capacity Color Barcode (HCCB) is a technology developed by Microsoft for encoding data in a 2D "barcode" using clusters of colored triangles instead of the square pixels conventionally associated with 2D barcodes or QR codes.
It is possible to generate your own, downloadable QRpedia code images programmatically, by minting a URL in the form: http://qrpedia.wikimedia.org.uk/qr/php/qr.php?size=800&download=NASA%20QRpedia&e=L&d=http://en.qrwp.org/NASA. Note that you can amend some parameters. |size= is the dimension of the (square) image in pixels.
A UPC-A barcode. A barcode or bar code is a method of representing data in a visual, machine-readable form. Initially, barcodes represented data by varying the widths, spacings and sizes of parallel lines. These barcodes, now commonly referred to as linear or one-dimensional (1D), can be scanned by special optical scanners, called barcode ...
Almost all two-dimensional bar codes such as PDF-417, MaxiCode, Datamatrix, QR Code, and Aztec Code use Reed–Solomon error correction to allow correct reading even if a portion of the bar code is damaged. When the bar code scanner cannot recognize a bar code symbol, it will treat it as an erasure.
Rectangular Micro QR Code (also known as rMQR Code) is two-dimensional (2D) matrix barcode invented and standardized in 2022 by Denso Wave as ISO/IEC 23941. [2] rMQR Code is designed as a rectangular variation of QR code and has the same parameters and applications as original QR code.
