QR codes are small, pixellated black and white squares that work in a similar way to barcodes.
They can contain any information you like. Most QR codes are used to store website addresses and contact details.
QR codes can be ‘scanned’ by most smartphones with cameras – including iPhones, Android devices and BlackBerries. They’ve become widely used on adverts, packaging and more.
