An eGate (electronic gate) is an automated self-service barrier that uses biometric technology to verify a traveler's identity against the data stored in their ePassport. The process begins when you place your passport's photo page onto the glass scanner at the gate's entrance. The system reads the digital chip inside your passport to retrieve your official photograph and personal details. Simultaneously, a high-definition camera at the gate takes a live "biometric" photo of your face. Sophisticated facial recognition software then compares the live image with the one from your passport chip, analyzing unique facial features such as the distance between your eyes and the shape of your nose. If the images match and the system confirms you are not on any high-risk watchlists, the physical barrier—usually a glass gate or turnstile—automatically opens to allow you through. In 2026, these gates are highly efficient, typically taking only 10 to 15 seconds to process a passenger. If the system fails to verify your identity (which can happen if you are wearing heavy glasses or a hat), a Border Force officer is alerted to conduct a manual check at a nearby desk.
