Once registered on the PARAFES system, passengers can then cross the border quickly, both when departing and arriving. They line up at the entrance of the automated airlock gates which are located next to the border police manual control booths. Firstly, following instructions displayed in front of them, passengers insert their passport into a terminal at the entrance of the airlock gate. After data has been scanned and registration verified, the airlock gate door opens automatically.
Passengers then enter the airlock gate and place a fingerprint on the sensor, again following instructions.
A biometric inspection is then carried out. If authentication is positive, the airlock gate exit door opens, and passengers continue on their way.
