Passenger identification refers to the process of verifying the identity of individuals traveling on various modes of transportation, such as airplanes, trains, or buses. This process typically involves checking government-issued identification documents, like passports or driver's licenses, to ensure that the person boarding matches the name on the ticket. Effective passenger identification is crucial for maintaining security and safety in transportation systems. It helps prevent unauthorized access and ensures that travelers are who they claim to be. Various technologies, such as biometric scanners and facial recognition, are increasingly being used to streamline and enhance this identification process.
