QR Code Demo

 QR - Quick Reader Code Demo

A QR code is a Quick Response code that is machine-readable.  It consists of an array of black and white squares, typically used for storing URLs or other information for reading by the camera on a smartphone.

Below, the Digital Literacy Network's Marc Czarnecki shows how a smartphone app uses the code to quickly provide an option from the camera app to open a link to the URL or Universal Resource Link (a web address); in the example below the QR code goes to a YouTube virtual demo of their community meeting room.
