I tried two QR readers on the photos in the article. They did not detect the code. Would it have been much more effort for the photographer to take a photo that was scannable? Or is there just too much variance in the arrangement and no reader would actually scan it even without a photo?

For what it's worth, "Barcode Scanner" on Android was able to scan it effortlessly.

I scanned it with WeChat and the public WeChatID of the company popped out - haomengshenghuo, whose direct translation of english is: life with good dreams.

It worked with the scanner in the built-in camera app in iOS 11, but I had to manually adjust the brightness (issue with scanning off a computer screen?)

Might be a problem with the combination of your monitor and your phone camera. I tried Barcode Scanner on Android, and it scanned it without a hitch. Hell, I had more trouble scanning a QR code I hand-drawn in blue on white paper...

  Huh, that's kind of odd. I use QR codes for lots of other things and they are successful, though the images are typically more clear.

  That is exactly working as intended. You need to install WeChat and use the app to scan it to go the official account of the tourism office.

It's Chinese, if there's a QRCode you need to use Wechat. I tried and it's working fine.

It worked for me. Opens wechat in the Play store.

An old QR app I had for a long time (from when QR codes were first introduced, many years ago) failed to read it too. Some of the bits look ambiguous too --- e.g. taking the upper left corner bit of the upper left locator square to be (0,0), what's the bit at (16,11)? It's both noticeably darker and lighter than its neighbours, like it was cut out and then grew back slightly. Those which can't read the code probably use traditional thresholding to reduce the input into 0-1 first, while those which can are using some variation of https://en.wikipedia.org/wiki/Soft-decision_decoding https://en.wikipedia.org/wiki/Soft-decision_decoding algorithm. It doesn't help either that the middle was blanked out, eating into the error correction budget.

It worked for me just fine using the QR Scanner on Wechat for QR code that leads to the "village's tourism account on WeChat".

QR Droid worked fine. So did Google Goggles.
