QR Code Misadventures

QR codes are as popular with advertisers as ever, so why is it that so many people use them without understanding the point? Since I'm so interested in online marketing, I scan almost every one I encounter. The trouble is, as often as not, the QR code doesn't link to a mobile-friendly site!

Consider this one. I was about to pay my water bill last evening when I realized that Greenville Water had helpfully included a QR code on the invoice with the invitation to pay online. Great, I thought, no need to go to my computer. 

And then this. Really? You think I can pay my bill on my phone with that? Thanks anyway, Greenville Water.
