Yet again another barcode / QR proposal. Can't speak for the Americas, but here in Europe QR codes aren't used that much, I feel, except maybe for mobile payments. Compare this with China, where QR codes are in literally every store, each taxi driver has a printed one nearby and even street food cards use them to pay. I can't see this one becoming popular, given how many are printed on glossy / dirty paper (often usi…

I think it's the same for the Americas, but just because the average person doesn't use QR codes very much that doesn't mean that such technologies aren't being used in ways that aren't widely reported. For instance, I know someone who placed small barely-visible QR codes in videos that get passed off to editors so that each clip and frame number(and other info) can be detected programmatically despite editing softwa…

Another interesting use case: Crowdmark[0], a digital grading platform uses QR codes printed on test pages to match these up to the correct student when they are scanned without the need for any manual matching process.

Every single container, crate, item and slab of raw material at work has a QR code attached.

They are fantastic for that use case as with high levels of error correction you can read them in a rain storm when one corner is missing.

That and every UPC scanner in existence seems to read them no problems.

One of the nice 'features' of QR codes is they're instantly recognizable as QR codes due to the 3 registration marks, and so it's obvious you could pull out your phone and scan one (not that anyone does that). JAB codes just look like a jumble of colored pixels -- it's not obvious it's encoded data, if you were to see this "in the wild". It kind of misses another potential feature, which is registration marks could a…

I use Alipay on a daily basis, all scanning QR codes.

I wonder if the 'Master'/'Slave' terminology is necessary here? Aside from being problematic, does it really describe the setup more than 'Primary'/'Secondary'?

The problem in this case, is that it's the terminology used by the standard:

Earlier quoted context omitted.

Because people cannot separate the abstract concept of slavery to the actual historical happening. Personally, I want to be a master to my mechanical slaves (tools, dishwashers, computers, robots) and can't wait for a future where machine-slavery is so pervasive that no humans need to work anymore.

Yup, it's censorship for the sake of censorship. We've had zero problems with master/slave terminology for decades because everyone dealing with it was cognizant enough to realize we weren't talking about human bondage. Then people who are incapable of compartmentalizing word connotations came in and declared their use "problematic" and demand everyone conform to their worldview and to waste time changing code commen…

"We've had zero problems with master/slave terminology for decades because everyone dealing with it was cognizant enough to realize we weren't talking about human bondage."

That's a pretty big assumption. Maybe people did have a problem but felt uncomfortable voicing that opinion or maybe having an industry overwhelming white no one had the experience necessary to notice that it might be problematic.

That it's "censorship for the sake of censorship" is just the most bad faith assumption you could make. Word choices change with the culture, it's a fact of life.

Facebook and Google use QR codes to link phones and desktops. It shows the QR code and your point your phone at it and that's it. I can't think of anything quicker. People sometimes say they're ugly. Who cares? You'd rather type a load of random crap instead?

On the other hand, this requires color ink. Traditional QR only needs black and white.
