Here are the three design options to choose from:
Standard Black & White QR Code:

2. Custom-design with Logo:

In this design, you can:
Edit the colour and pattern of the Eyes (three corner blocks) and Data Modules (round blocks)
Add a brand logo or image in the centre of the QR Code
Export the image in Raster (PNG, JPG) or Vector (SVG, EPS, PS, PDF) image formats
3. Custom-design with Background Image:

In this design, you can:
Edit the pattern of the Eyes (three corner blocks) and Data Modules (round blocks)
Place a semi-transparent QR Code (black-and-white only) on top of a brand image
Export the image combination in PNG or JPG (as the uploaded background image will be in PNG/JPG)
In all the three designs, you'll notice that the QR Code architecture remains the same and only the colors and patterns change. To know more about design options using Scanova, see: Custom QR Code Design.
