The use of virus contact-tracing apps should be voluntary, the European Commission will say on Wednesday, as part of a package of measures aimed at lifting border restrictions and reviving the European Union's tourism and travel industries.
The apps should also be able to work across EU borders, a Commission document seen by Reuters said.
