QR code. A person using a smartphone to scan a QR (Quick Response) code. This is a matrix barcode, or two-dimensional barcode, that is often used to provide links from physical resources (e.g an item on display in a gallery) to related online resources that can provide more information or links to commerce sites. The QR code contains much more information than a conventional vertical-striped barcode. Photographed in a council building in Yekaterinberg, Russia.
