What is the difference between SmartGate at arrivals and at departures?

Arrivals SmartGate

The arrivals SmartGate uses a two-step process, which involves a kiosk and a separate processing gate. First you must answer a few eligibility questions at the arrivals SmartGate kiosk. Then you must proceed to the gate for your identity check and clearance.

The arrivals SmartGate was rolled-out in 2007. Major advances in facial recognition and gate technology, in terms of performance and reliability, has been made since then.

Departures SmartGate

The departures SmartGate is a simple one step solution that uses the latest in face recognition and matching technology. It performs the same role as the arrivals SmartGate kiosk and gate.
