Creating QR Codes:

qrencode -m 2 -t EPS 'bitcoin:hörönlörönjahalitulijallallei' > key.eps
epstopdf key.eps

You can get those programs this way:

qrencode is available here:

http://fukuchi.org/works/qrencode/index.html.en

But it is available at least in Debian GNU/Linux.

epstopdf belongs to TeX Live, but it also has a homepage here:

http://tug.org/epstopdf/

TeX Live also has a command called epspdf.

XeLaTeX-command:

xelatex -src-specials -file-line-error -recorder -output-driver="xdvipdfmx -q -E -p a4 -l" bitcoinwallet.01.tex

Sometimes that “-output-driver” thing is needed but sometimes not:

But you can scan its QR Code from that PDF file called
bitcoinwallet.01.pdf .

If I start using any other crypto currencies, I release their
