You'll soon be seeing QR Codes in a beauty magazine advert, on a billboard, a web page or even on someone’s t-shirt. Once it is in your cell phone, it may give you details about that business (allowing users to search for nearby locations on the internet), show you a URL which you can click to see a trailer for a movie, or it may give you a coupon which you can use in a local outlet or details about the person wearing its on the t-shirt.
The reason why they are becoming widely used is that modern cell phones can scan (take a picture) of them. The cell phone needs a QR code reader and only take’s a minute for a iPhone or Android phone to install the reader. You can easily generate your own (quick response) QR code using a site like (www.kimtag.com) or the new Google QR generator and its free.
