Singapore announced Friday that it is developing a wearable for contact tracing. More than 35,000 people have signed a petition against the devices. The wearable devices would help Singapore s 5.7 million citizens track whether they were exposed to someone who has tested positive for the virus. The devices will not have GPS, internet or cellular connectivity, but will instead use Bluetooth proximity data to collate prolonged, close contacts. The data would then be encrypted on users personal devices and erased after 25 days.
