The brand new system, which is specified by a sequence of white papers, would use short-range Bluetooth communications to determine a voluntary contact-tracing community, preserving in depth knowledge on telephones which have been in shut proximity with one another. Official apps from public well being authorities will get entry to this knowledge, and customers who obtain them can report in the event that they’ve been been identified with COVID-19. The system will even alert individuals who obtain them as to if in shut contact with an contaminated particular person.
