QR codes can be found on posters, business cards, in newspapers and magazines and on the internet. The black-and-white barcodes usually link a mobile device to online advertizing or product information when it scans them. And that's just where the danger lurks, because hackers can create fake QR codes that link users to websites with malicious software. In this way, harmless advertizing poses a potential danger to the smartphone.
