I've just responded to a criticism of QR codes. QR stands for Quick Response and refers to 2-dimensional bar codes. BA have an app that allows me to get through airport security and board BA flights with an iPhone, using a QR code.

The criticism centres on how they can be used to direct smart phones that are capable of reading them, to spam/malware sites with dark intentions.

It reminded me of how easy it is to rubbish the tool because of one of its applications.

QR codes are not very interesting to look at, so I've used a picture of another tool being applied in a contentious way.
