The Government have launched a service that enables you to generate a QR code for display in your venue. This will work with the NHS Covid-19 app due to launch soon.
You should create and display a QR code if you are:
· a business, place of worship or community organisation with a physical location that is open to the public
· an event which is taking place in a physical location
