Tuesday, 20:24, 09/02/2021 Many Vietnamese companies have developed IT applications for COVID-19 prevention and control and online learning during the pandemic. Since early 2020, the Quang Trung Software City has been using an automatic body temperature measurement system it installed at TMA Building and Building 1. It warns using sound and images when someone walks in with a fever of 37.5 degree Celsius or more. It said the system should be used at all buildings and quarantine areas in place of people carrying digital thermometers to reduce the risk of transmission. QTSC has also developed a system for face identification, which sets off an alarm if someone not wearing a mask enters a building.
