IOM PassPort™ SL Walk-Through System

people walking through identification system

SRI offers a flexible biometric system for identity authentication and access control in high-throughput applications. The IOM PassPort™ SL product leverages the free flow and proven performance of Iris on the Move® (IOM) technology with the flexibility of a modular walk-through design.

Customers can easily integrate SRI’s unique face capture and iris recognition components directly into their own turnstiles, infrastructures, or entrances. The versatile configuration minimizes changes in existing operational procedures or hardware.

With a processing speed of 30 people per minute, the PassPort SL’s no-contact capability solves the identification challenges associated with crowding and infrastructure limitations. Users simply walk through at a natural pace. It is ideal for use in airport terminals, large entertainment venues, corporate lobbies, and security checkpoints.
