Whatever happened to QR codes?

I remember pitching an idea using QR codes about two years ago.

I'd seem them used a lot in Tokyo where I'd recently been on holiday.

At the time it was felt that it was too soon as hardly anyone in Australia had a QR code reader.

Fast forward to today and nothing much has changed.

QR codes pop up from time to time but the number of people with readers is still very low.

Which has me wondering if they'll ever take off in Australia?

I suspect not. But then again you never know.

So what do you think?
