Another massive use of artifcial intelligence systems in tourism is represented by some widely used forms of AI in airports these days, such as facial recognition systems for airport security. Facial recognition is a biometric technology, that greatly increases the efciency of passenger screening by automating the process of verifying photo identifcation at the airport. According to the New York Times , airports are looking for additional ways to use 12 biometric verifcation methods like facial recognition. The National Institute of Standards and Technology has also discovered that facial recognition is 99.5% accurate . Soon, all 13 airlines will require passengers to go through biometric verifcation before boarding planes. Then again, the relevance of biometric systems in tourism, and particularly at airports, as well as the need to establish certain legal rules for such systems, is also underscored by the European Committee on Transport and Tourism, that in 2022 has issued a draft opinion on these topics. In particular, the relevance of biometric systems is highlighted 14 in Amendment 3 of the draft opinion cited, where is stated that the Proposal Regulation This information is available at the link: https://www.nytimes.com/2021/12/07/travel/biometrics-airports- 12 security.html.
