Visitor management systems that required many shared touchpoints or were slow, cumbersome and caused congestion suddenly posed newfound health concerns. Biometrics can eliminate the need for physical touchpoints by using a person’s face, voice or iris. Modern biometrics are mobile and frictionless, using a device’s native camera and microphone to perform highly secure and convenient identification and authentication without need for specialized equipment or hardware. The average person’s hands typically carry at least 3,000 different bacteria belonging to more than 100 species, according to US researchers.
