TSA exploration of biometric solutions is based on rigorous scientific study and analysis. We are aware of a variety of public concerns related to the accuracy of biometric technologies and take this issue seriously. Along with our federal partners, we are carefully studying biometric solutions in both laboratories and operational environments to proactively identify and mitigate performance issues up front. Accuracy and equity in biometric system performance is a key issue for TSA, and one we are carefully studying to ensure we understand the full benefits of this technology and make informed decisions to mitigate risks.
