That is correct! The Transportation Security Administration (TSA) in the United States has been rolling out a new system at select airports aimed at making the security process more efficient. Through biometric technology, specifically facial recognition, TSA PreCheck passengers no longer necessarily have to present their physical IDs or boarding passes at the security checkpoint.
However, travelers should keep in mind that they are still required to carry their IDs while traveling, as the facial recognition technology is still in its developing phase and may not be available
