Member States, with the support of the European Commission, have reached an agreement on a set of technical specifications that will allow the exchange of information between national contact tracing apps. The specifications will concern the majority of tracing apps that have already been rolled out, as well has apps still to be launched in the EU. 

The solutions means that national apps will work seamlessly when users travel to another EU country - something that is important as countries begin to lift restrictions that will allow summer vacations to take place. The technology has been made possible through the implementation of a decentralised approach, which is another step towards interoperability of such mobile apps. 

The exchange of information shared between apps will be encrypted and follow strict EU guidelines on data protection.
