I trust many Hongkongers have heard about the LeaveHomeSafe coronavirus tracing app - but how many have actually downloaded it? Similar tracing apps have been in use for a while in other parts of the world, from Singapore to Britain. The British QR code system is not foolproof and customers unwilling to comply are free to just walk away from the premises. How successful will the SAR's tracing app turn out to be? It all boils down to how far the public is willing to place their trust - in the scheme as well as those administering it.
