The app, which alerts smartphone users if they have been close to confirmed cases of coronavirus, launched earlier this month and has been downloaded by more than 35,000 people. At least four people have been contacted via the app to let them know they may be at risk.
And those with the app simply need to keep it active while in Scotland and Northern Ireland and their phone will be able to interact with similar apps in those jurisdictions.
It is hoped that the Jersey app will soon be able to be paired with versions for England and Wales.
Developed by the government in partnership with Digital Jersey, it has brought an additional dimension to the Island’s efforts to combat Covid-19.
The government have said that securing partnerships between other jurisdictions is something they wish to pursue as it will help individuals who travel and those close to them.
Julian Blazeby, director general for Justice and Home Affairs, said: ‘The Jersey Covid Alert app is a vital tool in helping suppress Covid-19 and I welcome that the app now works with other alert applications in Scotland and Northern Ireland.
‘This compatibility will allow those travelling to continue to be alerted via the Jersey Covid Alert app, if they have been in close contact with a positive Covid-19 case while in Scotland or Northern Ireland.’
The app is designed to complement the existing contact tracing methods.
