QR Codes

From the Wikipedia entry: A QR code (quick response code) is a two-dimensional barcode invented in 1994 by the Japanese company Denso Wave. A QR code is a machine-readable optical label that contains information about the item to which it is attached. QR codes often contain data for a locator, identifier, or tracker that points to a website or application.

Most browsers will create a QR for the address of a site page. In Edge I right-clicked anywhere on our ToC Home page, and selected Create QR code to generate the QR code for our ToC site which appears on the right.

Camera App

The camera app on many modern mobile phones will detect the link or other information stored in a QR code. I pointed my phone camera at a coupon that came with one of my recent Amazon Prime orders. Holding the camera steady over the QR code causes a prompt to appear showing the link. Clicking on the link takes the browser to the page concerned.

QR Scanner Apps

If you phone camera does not support QR code capture you need to download a QR code scanner app from your phone's app store. There are usually a great many free QR scanner apps available so make sure you choose one with the highest rating assigned by other users of the app. Just launch the app when you find a QR code on any printed material. Point your camera at the QR code and hold steady while the app detects it and then gives you a prompt similar to one on the right.
