cat address.txt | qrencode -t SVG -o address.svg

sudo apt-get install qrencode

Einen QR-Code erstellt man mit:

qrencode -o meinqrcode.png "Hallo Welt!"

File: address.txt

BEGIN:VCARD
N:Marianne Mustermann
URL:http://www.marianne-mustermann.de
EMAIL:info@www.marianne-mustermann.de
TEL:+49-1234-567890
END:VCARD

To convert this into the code, use:

cat address.txt | qrencode -o address.png

For example, if we wanted a 10×10 pixels QR code, we’d have to type the following instead.

qrencode -o m_wikipedia_big.png –s 2 http://en.m.wikipedia.org

qrencode -o qr_mecard.png 'MECARD:N:Max Mustermann;TEL:+49-123-45678;EMAIL:muster@mann.de;URL:http://home.page.com;ADR:Adresse;BDAY:19701228;NICK:musti;NOTE:keine Notizen;;'
