Vueling was the first airline in the country to implement this controversial identification method. In 2021, he launched the pilot program developed by AENA in Barcelona and, after deeming it a success, decided to install it at the airports of the Catalan capital and the airports of Madrid, Menorca, Palma de Mallorca, and Ibiza. He announced on Wednesday that he would “soon” expand his scope to include the northern regions of Gran Canaria and Tenerife. Other airlines, such as Air Europa, Inter, and Iberia, are also participating in this initiative. Recognition systems using AI extend to more and more aspects. They are used to unlock the mobile phone screen and to prove to your bank that you are the account holder. To do this, they analyze biometric data, which is extracted from each person's unique characteristics, such as fingerprint, iris, and face. Its uniqueness makes it particularly sensitive, as, in the wrong hands, it can facilitate forgery and impersonation.
