Nintendo used to like to use QR codes for sharing level data (i.e. look at Pushmo, etc), and I always thought it was clever and there should be more of that. I just had to scan some internet forums for an interesting looking level, bring the game up on my 3DS, scan the code, and voila! I had the level in the game. I'm surprised they didn't do that for Mario Maker level codes.

Animal Crossing uses QR codes for sharing player created designs (clothes, paths, flags, etc.)

I wish the major mobile operating systems had built in support for them. I think that is the greatest hurdle to adoption in my opinion.

Agreed. I recently wanted to read one, and had to pick one of the many. It's always a fun game trying to pick which one of the many that won't phone home what and where I scanned.

I was on a US continental flight yesterday and my boarding pass was on my phone as a QR code.

Flights are one of the very few areas I have found QR codes to be useful. I'm usually able to check-in on my phone during the drive to the airport, add it to Passbook, and by the time I'm at the TSA screening area the ticket has made it's way to my watch. I'm always a little wary of clunking my watch on the glass screen of the barcode reader, but haven't had a problem yet.

One time, on an American flight, the scanner at the gate was somewhat of a C shape and my watch + wrist wasn't able to fit inside of it, which was quickly resolved by pulling out my phone and sliding it into the scanner.

On another positive note, TSA agents love it and always accuse me of being James Bond. Makes the screening process much more fun.

They are used a lot with Bitcoin, whatsapp uses them for pairing with the web interface, authenticator uses them to import keys.

I think they're great. They're very fault tolerant and can contain a ton of information. It's a great way to scan stuff from you computer (or anywhere else) and import it into your phone.

QR codes are legitimately great for what they're good at: barcode replacements. And in answer to your question, yes, their usage has grown and expanded. While traditional barcodes remain for basic UPCs, a lot of manufacturers are utilising QR codes for expanded product information. The way that QR codes failed is that marketers and technologists wanted to use them for everything. Website URLs, business cards, phone n…

I wouldn't say they "failed". QR-codes are one of the things which are now everywhere and weren't there a few years ago at all (see barcodes weren't use in all the places where now a QR-code stands).

The fact that not many people cares to scan them (citation needed) is a different thing... still they are quite popular.

I use them constantly as a way of getting info from my computer to my phone.

I use this bookmarklet to quickly generate a qr code that is either 1) the url of the page, 2) the text that is currently selected, or 3) the text entered into the popup:

  javascript:(function(){var stext = window.getSelection().toString(); text = stext == "" ? window.location : stext; text = window.prompt("Enter Text to Make QRCode", text); window.open("https://chart.googleapis.com/chart?cht=qr&chs=500x500&chl="+encodeURI(text)+"&chls=H","qrlink","width=500,height=500");})()
