Singapore considers wearable trackers after app failures
After problems with its TraceTogether contact tracing app, Singapore is planning a comprehensive contact tracing system in which it will distribute to all its 5.7 million residents a wearable device that will identify people who have interacted with people carrying the coronavirus. The devices can be worn on a lanyard or carried in a handbag. Critics are concerned that it will be difficult to tell what the device is doing or what information it sends to back-end servers.
