The Transportation Security Administration (TSA) is exploring and implementing technological upgrades for TSA PreCheck passengers to improve security and efficiency.

Initially, the agency considered a policy to allow PreCheck travelers to bring water bottles through checkpoints at airports equipped with advanced CT screening technology. This technology can distinguish water from other liquids, though the TSA noted that nationwide rollout was limited by technology acquisition and funding.

Following these considerations, the TSA announced plans to implement new screening setups at seven airports. This initiative, intended to double passenger throughput, includes electronic gates for facial-matching identity verification and the potential use of Advanced Imaging Technology body scanners. The rollout also incorporates ‘image on alarm’ automated bag screening software to flag threats for officer review.
