How Do QR Codes Work?

QR codes are popping up everywhere these days. Many companies see them as a unique way to advertise a product and can drive a lot of customers to web page or advert without the customer even knowing where the link is taking them. Part of what has made the use of them rise in the last 5 years or so is the sudden boom in the smart phone market. Since the launch of the iPhone in 2007 and Android phones shortly after, mobiles have had the capabilities to read QR codes and take the user to their destination.

QR codes are often used at the bottom of posters so that the user can view a trailer of the film they thought looked interesting from the poster. Some QR codes are used on TV, in cinemas or even with in video games. Now images can be embedded onto a QR code such as the advert for Brand Ninjas that we currently have in our sidebar.
