KLM and Schiphol Group are studying a 100% self service passenger flow system called 'Happy Flow' that will see facial recognition technology used to identify passengers at check-in, bag drop, border control and aircraft boarding, reports travel media.Developed in collaboration between Vision-Box, the Netherlands, Aruba Airport Authority, Schiphol Group and KLM, the system was inaugurated in May 2015 in Aruba and will be operation during the next two years.According to a report by Future Travel Experience, Manuel van Lijf, Director Product Innovation at Air France-KLM, revealed at the launch of Aruba Happy Flow that KLM and Schiphol Group are already undertaking a feasibility study on how Happy Flow could be implemented at Amsterdam Airport Schiphol.”We're already talking to a few other airports at the moment that want to better understand how it works. The benefits are so enormous on so many levels,” van Lijf said. He did, however, warn that “every airport is different and the model can't be copied directly, one on one, from one airport to another”.
