How do passengers know whether they are in the right place? Scarabee and KABA have designed, developed and implemented tailor-made, integrated airport access gate systems. Clever use of clear green lighting indicates which gates are open. Passengers with a valid boarding card receive real-time notification of their departure gate, as well as a warning if they are in the wrong location and where they should be. Security staff can open gates easily using special passes in case of large groups or unforeseen situations, and airport information systems are continually updated.
