Intent is unclear - QR codes are most often poorly labeled.They often appear at the bottom of an ad, on a business card, or on a webpage with little or no labeling.QR codes are polymorphic so the user has no reasonable way of guessing what's contained in a QR code before opening it.Clients are not ready - Unlike phone numbers, QR codes cannot be manually entered and are not easy to cut and paste (many clients/devices are poor at graphical cut/paste).Therefore, user abandonment is high even when intent to use is there.UX improvements We need clients, not apps - Today most users read QR codes via smartphone or desktop apps.This presents a hurdle to users who have to find and fire up the app, then figure out how to enter the QR code.It's better to remove this layer and have QR codes become readable at the point of reading.Being able to see a QR code on a browser and right-clicking on the image to bring up a contextual menu to decode the image.having a QR reader built into camera software for a mobile phone and webcam clients instead of having users go hunt for a separate reading app.
