Air transportation IT provider SITA has developed biometric technology to simplify the airport security process. SITA Smart Path will scan a passenger's face, compare it against travel documents and create a secure token passengers can use for check-in, bag drops, border control and gate access. A SITA spokesman said Smart Path went through a trial at a major airport hub in the Middle East this year. SITA is working with "a number of major airlines and airports" to integrate the technology, and it projects biometrics will be common at airports by 2020.
