This summer Amsterdam Airport Schiphol will initiate a centralized security system in its terminal. From that time on, passenger security checks will take place directly after the passport or ticket check. Current security checks are decentralized and located at the entrance to each pier. The structure will remain the same, equipped with metal detector portals and x-ray machines for the hand luggage.
Amsterdam Airport Schiphol arrived at the decision to change its security structure following extensive deliberation with the Dutch Ministries of Justice and Traffic & Public Works, the Seceurop security agency, the Royal Marechaussee, KLM and other airlines represented in the Schiphol Airline Operators Committee. Many major European airports are already employing centralized security.
Quality Improvements
The introduction of centralized security will improve the quality of service to passengers since it will result in fewer waiting periods. The passengers will go through passport (or ticket) and security checks in rapid succession and then find themselves in a clean area. From there they can progress straight to the aircraft without any further interruptions. This should also work well for general takeoff punctuality. The situation will be similar for transfer passengers. After passing through centralized security they can change planes more quickly.
Extra Portals for Passengers and Personnel
All Schiphol staff and their belongings will also be checked before they can move into the clean area. New personnel portals will be created in the terminals for this purpose. To limit the length of waiting time for passengers at the combined passport, ticket, and security checkpoints, Schiphol will build extra checking areas in the months to come.
Departures Hall 1 (the Schengen terminal) will have two ticket and four security checkpoints. Departures Hall 2 and 3 will each have six passport and four security checkpoints.
