I like the QR code feature, but we have printed materials that we're using them on and the .png file format for the image is poor. Even slightly upscaling the image makes it blurry and less professional looking.
It would be nice to have a QR code that is in a vector format so that it can be easily scaled. People are not always standing right in front of the paper, and may try to capture the code from a distance.
Besides usability, there is definitely an amateur-ish feel to grainy images. Thank you!
