The new system, which is laid out in a series of documents and white papers, would use short-range Bluetooth communications to establish a voluntary contact-tracing network, keeping extensive data on phones that have been in close proximity with each other. Official apps from public health authorities will get access to this data, and users who download them can report if they’ve been diagnosed with COVID-19. The system will also alert people who download them to whether they were in close contact with an infected person.
Apple and Google will introduce a pair of iOS and Android APIs in mid-May and make sure these health authorities’ apps can implement them. During this phase, users will still have to download an app to participate in contact-tracing, which could limit adoption. But in the months after the API is complete, the companies will work on building tracing functionality into the underlying operating system, as an option immediately available to everyone with an iOS or Android phone.
This will NOT end well for us users sadly, especially it's proven that Bluetooth-based tracking isn't effective plus it will be ripe for abuse by governments.
