Biometrics is already a reality and it is becoming more and more accepted by users.
One of the settings in which new developments are being implemented using this technology is airports. The long queues and the increasing number of passengers is something that makes most people uncomfortable when traveling. In this sense, biometrics helps speed up these processes with fingerprint readers and facial recognition, among others.
It is about seeking comfort in an activity such as traveling, in which the number of passengers increases significantly year after year as indicated by different IATA studies (the International Air Transport Association).
The pioneer was Changi Airport, Singapore, turning its T4 into the first terminal with a free flow of passengers in the world in 2017. Others, such as the airport in Oslo, Norway, also recently started to implement these technologies where the information collected is monitored by the local police.
