Airport biometric tech firm SITA has implemented phase 4.0 automated passport control (APC) kiosks in McCarran International Airport in Las Vegas, extending the technology to passengers from visa waiver countries.Now, business or tourist visa holders, Mexican travelers with border crossing cards, and airline crew members will be able to use the kiosks upon arrival in the U.S.Rosemary Vassiliadis, Clark County Director of Aviation, said: "McCarran welcomed nearly 43 million travelers in 2014 – the most since 2008 – with much of that growth coming from outside the U.S. We expect the volume of international travel will continue to rise, and offering the speed and convenience of SITA's APC self-service kiosks for passport processing to a greater number of travelers will allow us to accommodate that growth while continuing to deliver an exceptional guest experience."McCarran first deployed SITA's APC Kiosks in March, allowing passengers to provide their travel document, biometric data and customs declaration prior to speaking to a U.S. Customs and Border Protection (CBP) officer. Phase 4.0 increases eligibility from the previously established 38 "visa waiver" countries outlined by Customs and Border Protection to virtually all of McCarran's international arrivals.Phase 4 SITA kiosks also feature enhanced embedded video.Paul Houghton, SITA President, Americas, said: "SITA is helping airports worldwide deliver an end-to-end, hassle-free and secure passenger journey. Whether at check-in or upon arrival, automating routine and often time-consuming processes like passport control has proven to significantly cut wait times, enabling airports to improve operational efficiency and passenger satisfaction. In the U.S. our automated passport control kiosks have reduced wait times for passengers by as much as 40 percent."Phase 4.0 will allow travelers from the countries with the largest total growth percentages – China (172%), Colombia (72%), India (47%), Brazil (43%), and Mexico (38%) – to process themselves through the kiosks.
