At first blush, QR codes would appear to offer nothing but upside. A quick scan of a mobile device across an odd-looking square symbol, and the user is presented with your company’s landing page, how-to video or promotion.
No wonder QR codes have proliferated in the past couple years, and are now found everywhere from sales literature to retail displays and transit advertising. Anyone can create a QR code, and anyone with a smart phone can read it. But their very simplicity also leaves QR codes susceptible to misuse.
