Brands have found a new way to engage their customer and it all fits in this little square called a QR code. These are becoming very common on packaging and all you have to do is take a picture of this little code and your smart phone takes you to a mobile site where you can access promotions, product info, origin, ingredients, etc. QR or 'quick-response', codes are a form of two-dimensional code that are capable of encrypting large amounts of data in a square of black and white dots. This is a great way to communicate to the customer without increasing the packaging size or label space. This technology has been around for a while in Japan and is growing in Europe and the US.
