HCC2D Encoder — Written by Marco Querini

HCC2D Codes

HCC2D (High Capacity Colored Two-Dimensional) is a colour barcode format that extends QR codes by encoding data in coloured cells, increasing data density while preserving QR-style robustness and error correction.

Decoding. HCC2D Decoder is available on Google Play, on Huawei AppGallery, and on the App Store for iPhone.
Encoding. Beyond the online generator, HCC2D Encoder is also available on the App Store for Mac. An open-source single-file command-line C encoder is also available on GitHub, and Debian/Ubuntu users can install the packaged CLI encoder from the official HCC2D APT Repository. HCC2D API is available for programmatic generation from any language or platform.
