Ensure scanner reader/app is appropriate for your mobile device
Test for compatability & full functionality of QR code
Test different scanner readers/apps
I don’t think I really have to emphasize how important it is to test your codes.
Does your code do everything it’s supposed to? If not, check your reader….. Is it appropriate for your device, specifically the version, OS model of your device?
Looking for a scanner app for your device?
App store
Google: “device name” qr readers

So what is really going on in the previous real world examples is - object hyperlinking.

21. “Finally, the greatest importance of QR codes could lie not in their specific use, which may be superseded by newer codes and interpreters, but in the opportunities they offer for moving away from keyboards as input devices in learning environments.”
