To scan a QR Code on your smartphone or tablet just open your QR Code reader app (plenty of good free apps out there), point the camera at the code and hey presto the QR Code "hyper-links" you to the web.
Now if it's a good application of a QR Code then the web page you land on will be relevant to the subject of the paper article or promotion. Also the website will be optimised for a mobile device screen.
Oh and of course, the actual location of the QR Code will be sensible - placed next to the article/promotion, easy to scan, good size, good quality, reliable signal...
Well sometimes the location of QR Codes are not ideal.
Indeed sometimes the locations of QR Codes are downright dangerous. Or if not dangerous...then very silly!
Here are 5 great examples of where NOT to place QR Codes.
Tricky...
Maybe a passenger can do the scanning?

No.

No!
Is it a bird?
Is it a plane?
Nope.
It's a giant flapping QR Code.

Missed it.
Can we go back around?
I know I'll get it next time...
My camera can't quite focus it....
maybe if I was to just climb over the rails...
So after being electrocuted and knocked over by a train...there's no signal!!!
My favourite is number 2. What's yours?
