Yes. Airports in Hong Kong, Singapore, hospitals in Singapore even schools in Japan have the temp sensor where you can see on a screen the temp of every individual in a group as they move pass. The sensor can set off an alarm if it detects anyone with a temp of say 38 deg.
Somehow we don't seem to see these in Australian airports ? We still using handheld thermometers
HongKong buses have installed temperature sensor at the door that can measure everybody passing through in seconds.
