Description from store
Shows a QR-Code for the current URL, or any other text.
It uses Kazuhiko Arases JavaScript library (http://www.d-project.com/) to draw the QR codes instead of relying on some third-party web API (like all of the other extensions I looked at.).
It's free and open source: https://github.com/fxkr/chrome-qrcode-extension
