ABSTRACT
Quick Response (QR) codes are a familiar feature when shopping, parking the car, or visiting a museum and can sometimes be found on clothing. Wherever information can be shared, a QR code can be used. The QR code aims to communicate complex ideas through a 2-D barcode, similar to the codes found on any household item one scans when doing self-service shopping. In a school setting, teachers use a QR code to provide additional instructions or resources next to wall displays, as an interactive way of communicating with parents or as a new learning technology. Key classroom information can be provided for parents, and a rolling programme of QR codes can support parents in helping their children's learning at home. Museums and outdoor attractions have led the way in the imaginative use of QR codes, and one may have visited a nature reserve or local gallery and been challenged to find things out or to follow an information trail.
