Across Asia and elsewhere, countries have deployed various technologies to help fight COVID-19, from contact tracing apps to QR-code check-ins for entering establishments. But some see Australian authorities' use of facial recognition and geolocation to enforce home quarantines as a step down a slippery slope, even as efforts to reopen borders come as a relief.
