The so-called NHS Covid-19 app will ask users who have been near someone with a positive coronavirus test result to self-isolate for 14 days. It will also allow users to check-in to pubs, restaurants or other venues by scanning a QR code on their phone. They will then get an alert telling them to self-isolated if other visitors at the same time are found to have been infected.
Restaurants, bars and other leisure facilities should display an authorised QR barcode on a poster or digital sign, which the app can scan. We have already set the track and trace system up at the FIA Hampton Office to ensure that our delegates are able to be informed in any worst-case scenario. The track and trace app and accompanying QR join a suite of measures that have been implemented at our FIA Hampton Office to provide a training centre that is socially-distanced and as safe as possible for our learners.
The app works when two devices running the app are within close proximity ( between 0-4 metres). The phones then 'exchange Bluetooth "handshakes" to determine the distance and duration, measured in sessions lasting five minutes'. If the points threshold is met and one of the two owners later shares a positive coronavirus test via the app, then the other will receive an alert.
