QR codes are a quick and easy way to create links to websites. QR codes can be used to post assignments or create a classroom activity. In the past you would have to have an add on or copy and paste the link into a website. 

A few months ago, Chrome received an update allowing for QR codes to be generated directly in Chrome. You can either access it in the address bar or right click somewhere on the page. Be careful not to right click on an image or video. If you do, you might just create a QR code to the image/video.
