The Irish company behind Ireland's Covid-19 tracker app has launched a similar service in the US state of Pennsylvania. It comes a week after NearForm launched its app in the neighbouring state of Delaware.
The technology is now being used in Ireland, Northern Ireland, Gibraltar, Scotland and will be launched in more US states over the coming weeks.
Yesterday, Jersey, the largest of the Channel Islands, announced it would also be using NearForm's app. The US service will allow for interoperability and exposure notifications across state lines that also have exposure notification apps and use the same Bluetooth technology.
