E-TAPS stands for “Electronic Travel Authorization for Passenger Screening.” It is a system designed to facilitate travel by allowing pre-registered passengers to move quickly through airport security checkpoints. This system is often implemented in airports to expedite the security screening process for frequent travelers or individuals who have undergone extensive background checks and security clearances. E-TAPS aims to enhance security while also improving the efficiency of the screening process, reducing wait times for travelers. However, please note that specific implementations and details may vary depending on the airport or country where the system is in use.
