Apparently QR code is a very useful thing to use, but not commonly used in Australia. I hadn't heard of it, and when I searched was a bit taken aback by its risks
In the case of no software exploits, malicious QR codes combined with a permissive reader can still put a computer's contents and user's privacy at risk. This practice is known as "attagging", a portmanteau of "attack tagging". They are easily created and can be affixed over legitimate QR codes. On a smartphone, the reader's permissions may allow use of the camera, full Internet access, read/write contact data, GPS, read browser history, read/write local storage, and global system changes.
I dream, therefore I am.

I have a QR code that synchronises my phone with my PC for messaging. I agree there are risks, as there are with RF tags and even debit and credit cards, which can be scanned by a passer-by. To avoid the latter, I use tinfoil in my card wallet to shield the cards.
