Airport Biometrics: A Primer

View Cover




Biometrics is one of the most powerful, but misunderstood technologies used at airports today. The ability to increase the speed of individual processes, as well as offer a touch-free experience throughout an entire journey is a revolution that is decades in the making.

The TRB Airport Cooperative Research Program's pre-publication draft of ACRP Research Report 233: Airport Biometrics: A Primer is designed to help aviation stakeholders, especially airport operators, to understand the range of issues and choices available when considering, and deciding on, a scalable and effective set of solutions using biometrics. These solutions may serve as a platform to accommodate growth as well as addressing the near-term focus regarding safe operations during the COVID-19 pandemic.
