CHIBA, Japan -- A group of five students fidgeted while standing in line at Japan's Narita Airport as a safety officer pointed a contactless thermometer at one of them.
Even though the entire process takes just seconds, the students, who were visiting the Tokyo area on a long four-day weekend, looked tense as they waited for their friends to get the go-ahead from the officer. Relief washed over their faces as one by one they passed the screening with flying colors.
