QR or “Quick Response” Codes, are small printed bar codes that, when captured with a mobile device, allow users to visit web sites, send emails, get product information, see a location on a map, send a text message, play a video, interact with social sites, place phone calls (to numbers not in their address book), and many other actions, without typing a single character. Anyone with a smart phone can scan and read QR Codes with the click of a camera.
