update: a reader has sent in a version with even higher contrast saying it works best:

So hopefully we’re getting somewhere!

 

A lot of people had trouble scanning the QR code I made out of wine corks so I made some modifications to help it become more scannable.

Hopefully this version works a bit better.  Thanks to Robert McIntosh for the excellent idea of desaturating the photo and increasing the contrast.  And then making it smaller tends to help too.  But not toooo small.

Anyway, here’s the finished black and white QR code made out of wine corks.  Although, I must confess I like it much more in color!

Please let me know if it’s working or not.

It scans perfectly on my phone with Quick QR Reader, but then so did the original in color.  And people say it works on Android and it works on iPhone!

But then some very competent people are telling me it won’t scan on their iPhones/Androids/etc. so I am sure it could be improved.  Probably variations due to QR Code Reading App, monitor settings, how much you’ve had to drink, etc.

Naturally, it’s more likely to work if you’ve had a glass of wine.  Which is why it works every time for me. 🙂

Enjoy!
