Somehow, I think these kinds of "clever" QR codes would be less used. Most people aren't going to even notice that they are legit QR codes. QR codes are already underutilized enough, at least in western countries. Cool idea, though!

It’s my opinion that underutilization is because of application rather than any more ephemeral thing like appearance. QR codes haven’t had a killer app yet, and they tend to be used for marketing rather than any critical tasks that rely on the qualities that make it a useful technology. My guess is this will change as it’s become more or less a requirement to have a cell phone to function in western society.

QR codes haven’t had a killer app yet

Since the virus hit, where I live restaurants are prohibited by law from having reusable menus. Instead, nearly all of them have a QR code at the able that you scan to see the menu on your phone.

That could do it.

> it's become more or less a requirement to have a cell phone to function in western society Owning a cell phone doesn't mean everyone keeps it with him at all times, and this will limit potential uses. Hopefully people don't become tied to it that badly.

The people who are constantly pushing for everything to be on a cell phone presumably have never lost or broken one.

Thanks to Coronavirus I’m now using them daily in Australia to record my visit to places.

"QR codes haven’t had a killer app yet" When I lived in China, scanning QR codes was how we initiated payments for restaurants, groceries, couriers and other offline goods/services. It was also how we added people to WeChat. I would guess at least 20 million QR codes are scanned per day in Beijing.

That's a fact.

It's a thing we can't deny.

Like the fact that I will love you 'til I die.

I have a pet project, "Oh By"[1] that is a replacement for QR codes that does not require an app to create, or consume, and you can just chalk them up anywhere. The downside is that it is a centralized service. Further, you would need to trust that this centralized service would continue operating into the indeterminate future. Luckily I have a strong track record there. A very simple example use-case is here: https:…

From a practical perspective, the larger problem with this implementation is that unless you happen to have heard of your service (unlikely), it's not obvious what to do with the code, or even how to find out what it is. You need a distinctive, unique string format that yields to googling. Overloading the hexadecimal notation was a poor choice, in my opinion.

You are correct - there is a chicken and egg problem here wherein "Oh By Codes" are not useful unless everyone recognizes them for what they are.

Like I said - pet project. Nearly 100% of my time and effort goes to rsync.net, but we'll see ...

The big problem is that any random QR code could be malware or the like (not a big problem for the tech-savvy, but worrying for those who are not) and few urls are so unwieldy that QR codes work better.

I can see it being useful for stealth links to .onion sites which are generally impossible to remember and a pain to type out.

As an European I’d say over half of my mobile payments are already via a QR code (it triggers a direct debit from my bank app). It’s infinitely faster than going through online checkout forms.

Do you at least get a manual confirmation? Because if not, I've a QR code I'd like to show you...

You enter your PIN, or touch/Face ID.

Also 1) only works up to a daily limit which you can configure 2) it’s a SEPA transfer, goes straight to another local, very traceable account and not a random bitcoin wallet in case you try to pull that off :)

Slightly OT, but when migrating data between iPhones, the old iPhone displays an animated point cloud that appears to function like a QR code. You scan it with the new phone, and your data starts to migrate locally through Bluetooth. Other than aesthetics, what are the advantages of the point cloud? Higher bandwidth? Also, if you were to transfer 100s of megabytes of data from device A to B, using A's display and B's…

Here is a good demo of a streaming qr solution. Not ours but a good demo of the concept. https://youtu.be/_0djJ1aVEXs We use a similar method for offline wallet transfers of private crypto keys. I’ll note a couple things. Keep the frame simple and not too dense. Be careful on ecc settings. Higher res camera androids to be slower in our testing. Be ready to loop the series to catch missed frames. Gives your frames and…

I've been wondering how one could efficiently and reliably pack arbitrary data into YouTube videos, a hacky way to get free and obfuscated data storage. Streaming QR codes has been the most promising way I can think of, particularly since they offer resilience against YouTube's video re-encoding process and are standardized for far larger codes, which could be easily fit in a video for later parsing out by a tool. You could probably embed even greater data densities with a color QR solution too.
