“When travelers come off of an international flight, they are funneled through a secure pathway to the CBP inspection area. The airline transmits the biographic data to us. We verify that information when we read a traveler's passport and we make sure it's accurate.

Customs and border protection agencies identify you through a sophisticated "multi-layered" system of digital data and biometrics. Before your flight even lands, airlines are required to transmit Advance Passenger Information (API) and Passenger Name Record (PNR) data to the destination country’s authorities. This includes your name, passport number, birthdate, and even your travel history and payment method. When you reach a kiosk or an officer, they scan your Biometric Passport, which contains an embedded chip with your digital photograph and personal details. Modern "e-Gates" and "Smart Gates" use Facial Recognition Technology to compare your live face against the high-resolution image stored in the chip and the government’s database. Additionally, your fingerprints are often on file if you have previously applied for a visa or participate in "trusted traveler" programs like Global Entry. These systems are linked to international security watchlists (like INTERPOL) and internal immigration databases. By the time you say "hello" to a customs officer, they usually already have a digital "profile" of your trip, including where you stayed and when you last visited the country.
