There’s no need to be concerned about the upcoming COVID-19 App.
Businesses are simply being asked to provide QR codes in Pubs, restaurants, hairdressers, cinemas and other venues.
The government is encouraging people to utilise the service and you can help by creating a QR code for your business here – https://www.gov.uk/create-coronavirus-qr-poster
Following the launch of the new COVID-19 app, customers and visitors in England will be able to check-in on entry with their phone instead of filling out a check-in book or tool specific to a business. This will allow NHS Test and Trace to contact customers with public health advice should there be a COVID-19 outbreak.
