We’ve written about several tools that makde creating Qrcodes – 'two-dimensional barcodes made up of black squares on a white background – in Ubuntu easy, but the following tool, QtQr, beats them all hands down.
Along with the ability to quickly create custom QrCodes containing text, URLs, e-mail, SMS and telephone numbers QtQr also comes with a ‘decoding’ feature.

The code is also available on Launchpad @ launchpad.net/qr-tools
