Libqrencode is a library for encoding data in a QR Code symbol, a kind of 2D symbology that can be scanned by handy terminals such as a mobile phone with CCD. The capacity of QR Code is up to 7000 digits or 4000 characters, and has high robustness. Qrencode is a utility software using libqrencode to encode string data in a QR Code and save as a PNG image.

(default) -i, --ignorecase ignore case distinctions and use only upper-case characters. -8, --8bit encode entire data in 8-bit mode. -k, -c and -i will be ignored. -V, --version display the version number and copyrights of the qrencode. [STRING] input data. If it is not specified, data will be taken from standard input.
