The Seamless ABC eGate for border control is a new generation of intelligent verification terminal for port immigration scenarios. It integrates multimodal biometric recognition, machine vision, touchless verification and border inspection-specific security algorithms. Without requiring passengers to present documents or pause for cooperation, it can automatically complete person-document verification, identity authentication, anti-tailgating monitoring and risk early warning, realizing contactless, second-level and zero-stay passage. The equipment features high-traffic adaptability, high security level and high verification accuracy, greatly shortening clearance time and reducing manual workload. It has become standard equipment for smart ports.
