You’ve may have seen those strange-looking, random-like, black and white square logos on magazines, posters or sometime on a real estate listing.

These are not as random, as you would think. These are called QR codes.

WIKIPEDIA: “QR Code (abbreviated from Quick Response Code) is the trademark for a type of matrix barcode (or two-dimensional code) first designed for the automotive industry. More recently, the system has become popular outside the industry due to its fast readability and large storage capacity compared to standard UPC barcodes. The code consists of black modules (square dots) arranged in a square pattern on a white background. The information encoded can be made up of four standardized kinds (“modes”) of data (numeric, alphanumeric, byte/binary, Kanji), or through supported extensions, virtually any kind of data”

In short, a QR code gives the smartphone and tablet users, a way to quickly reach any given web adress, without having to fumble with, the sometime small and akward, touch screen keyboard. This is done with the built-in camera and a free QR code App, such as QR Droid, QR Barcode Scanner, Goggles for Android and QR App, QR Reader for iPhone (iPad and some iPod)

QR codes are best used in situation, where we are trying to invite the user to take immediate action with a minimal amount of effort. The example here demonstrate how a QR code can enhance a poster message and could also be used on a ‘Music Band’ poster to direct to a video preview.
