Places around the world are using biometric technologies for coronavirus contact tracing and surveillance. For example, a municipality in South Korea is expected to roll out a program that uses facial recognition to track infected people. Other countries plan to implement, or have already implemented, similar systems, and some U.S. states are moving in that direction. Companies are developing facial recognition systems equipped with body temperature sensing capabilities, and Seychelles International Airport just implemented such a system for traveler health screening.
