# Create QR-code from citeurl

How can I create a QR-code by using and citing an url from a bibliography-entry with \citeurl?

\documentclass{scrartcl}
\usepackage{filecontents}
\usepackage{qrcode}

\begin{filecontents}{\jobname.bib}
@article{test,
author = {A. Author},
title = {My Title},
url = {http://tex.stackexchange.de},
}

\end{filecontents}
\usepackage[
backend=biber,
style=archaeologie,
]{biblatex}

\begin{document}
\qrcode{\citeurl{test}} %<---- it does’t work
\citeurl{test} %<--- it works
\printbibliography
\end{document}


Looks like an expansion issue. \citeurl does not simply dump the url, it does a lot of formatting as well. From within biblatex you can use \thefield{url} to access the raw URL, so that you can define a new command
\DeclareCiteCommand{\citeqrurl}
