diagrams-qrcode (hackage): This library is able to draw diagrams of QR codes using the diagrams library.  In order to create the QR code itself, you may use either the haskell-qrencode library or qrcode library, both are supported.  In order to draw and save the diagram to a file, we suggest using either the diagrams-svg library (pure Haskell, fast, SVG output only) or the diagrams-cairo library (requires Cairo, supports many different output targets, including SVG, PNG, PDF, PS and directly onto a GUI).  For an example of how this library may be used, please see the examples on the source code.
