Not op but I think QR codes are great and here to stay. They might not be the most efficient or ideal on a technical level, but they are very intuitive with basically universal mindshare. People understand the concept of scanning barcodes.

Ever since Apple added automatic detection of QR codes to the camera app, I think they're pretty well cemented as a good way to transmit small amounts of data.

  Super convenient for getting guests connected to the Wifi; I have a shell alias that runs: qrencode -t utf8 "WIFI:T:WPA2;S:<GuestVLAN-SSID>;P:<SecurePassw0rd>;;"

I know this is beating a dead horse but: https://picturesofpeoplescanningqrcodes.tumblr.com https://picturesofpeoplescanningqrcodes.tumblr.com I don't think I've honestly ever seen someone use QR codes due to their own initiative. I.e, I've seen people use it to pair stuff (≈ Apple watch) and for 2FA etc. But I think the whole concept of QR codes on posters etc will never take off. It's probably quicker to type in a URL or search for it, the codes are also often time to small or cumbersome to actually scan successfully. I think the idea of augmenting meatspace content with some kind of hyperlink will finally be implemented on phones with NFC tags, especially since iPhones are starting to support background scanning. However, when/if AR glasses become mainstream, we will probably use visual markers, and perhaps they will be QR but I'm betting a more visual pleasing standard will come, that can be embedded in the physical space without being as jarring [0]. [0]: Consider the impressive tracking already implemented in ARKit 2 (https://www.youtube.com/watch?v=ZhHExAxyVow https://www.youtube.com/watch?v=ZhHExAxyVow). The image is however only recognised as being part of a pre-defined, hardcoded, set of images, but it's not hard to imagine Apple suggesting some "iQR"-standard which is less intrusive but much much much more computationally expensive to detect. I have implemented a silly POC conference app which recognises badges using ARKit 2 simply by using different enough images as background on the badges (wouldn't probably scale to a large conference however...).

  Microsoft came out with a similar 2d barcode using triangles and 4 colors: https://en.wikipedia.org/wiki/High_Capacity_Color_Barcode https://en.wikipedia.org/wiki/High_Capacity_Color_Barcode
