The QR-code comes together with the Colourpin II and is used to gain access to the library of all 2050 NCS standard colours in the app.
 
To scan the QR-code, first make sure to allow the Colourpin application to get access to your phones camera, then point the camera towards the QR-code and it will load automatically.
