A QR code (Quick Response) is a type of barcode first designed in 1994 for the automotive industry in Japan.
The code consists of black squares arranged in a square grid on a white background.
The code can be scanned by the camera on a mobile phone which then opens up the phone’s browser to give further information.
The web site can then be viewed or a video clip can be played.
One recent use in 2020 has been by restaurants displaying the menu on a QR code. Users can also order and pay for the meal this way.
Most Apple iPhones and some Android (Samsung, Sony, Nokia etc.) phones can read QR codes directly with the camera without the need to download a separate scanner App. Check the camera settings and ensure “Scan QR Codes” is set to “on”.
It may be necessary on some Andriod phones to download a QR scanner App from the Google Play Store on your phone and have this running in the background. There are many to choose from.
