QR (Quick Response) Codes are useful to guide users to a webpage. You may have seen them around. They are simple to set up and use.
There are many QR code makers. One we recommend is QRCode Monkey.
You can customise the QR code including adding a logo in it, and changing colours.
Paste your webpage URL into the box, set the options and get your QR code. Then use that code in your media.
Most iPhones can use QR codes without an app, and most modern Androids also have the scanner built into the camera. For older versions, the user will need to download a scanner app to use QR codes.
