The QR code is only failing in advertising contexts. Printed out your boarding pass for a flight lately? It probably had QR code, but the beauty is you barely needed to know about it. All you had to do was print your boarding pass and then stick under the scanner. In advertising contexts, you need to recognize the QR code, know what the hell it is, know how to search for an app in your phone's app store that will read it, download that app, open that app, and scan the QR code. All to be sent to an advertiser's website. For any consumer to do that, regardless of how interested they are in the ad, is a massive ask.
