The doors of the exit gate only close when the passenger will not be recognized by the system. But here is the innovation of ABC Gate V2: the not recognized person stops for few seconds in the central area of the gate where, after a determined period of time, a side door opens that will address the suspicious passenger through a predetermined route up to the manual check of the passport.  
In this way, the other passengers avoid to queue and create obstacles while they are waiting for the check.

The entire structure is designed to occupy as less space possible and to make the crossing agile, but also secure. A series of sensors and photocells provide the people counting to avoid the overcrowding of the area and the opening of the doors in case a resistance due to an obstruction or retention is detected.
