The 40-day Spring Festival travel rush has officially commenced. According to projections by the Civil Aviation Administration of China, during the 2025 Spring Festival travel period, civil aviation is expected to handle over 90 million passenger trips, averaging more than 2.25 million passengers daily and guaranteeing 18,500 flights daily. This represents an 8.4% year-on-year increase, potentially setting a new record high.

To safeguard travelers during this peak season, airports in Beijing, Hangzhou, and other locations have integrated a state-of-the-art security measure during this year's Spring Festival travel rush – A3-level certified millimeter-wave body imaging security inspection devices. These devices enhance the quality and efficiency of airport security checks. Notably, this is the highest industry certification recognized in domestic civil aviation security and marks the first deployment of such equipment at Chinese airports. With these devices installed in fast lanes, the average personal security check time for passengers has been reduced from 30 seconds to 15 seconds.

At Hangzhou Xiaoshan International Airport's security checkpoint, reporters observed that passengers passing through the millimeter-wave body imaging security lane only need to follow on-site instructions and video demonstrations, open their hands, and stand briefly. The device swiftly displays the inspection results post-scan, ensuring no physical contact during the process. Security personnel can then promptly complete passenger security checks based on these results. Mr. Yao, who was preparing to return home for the New Year, remarked that while he frequently flies and undergoes thorough security checks, this seamless experience was unprecedented.

"To offer passengers an improved travel experience and elevate security check efficiency and quality, we continuously integrate new technologies," said the head of the relevant equipment usage department at Hangzhou Airport. "The standout feature of the millimeter-wave body imaging device is its speed, cutting the average security check time per passenger from 30 seconds to 15 seconds. This not only ensures safety but also significantly boosts passenger travel efficiency." The airport introduced this device in mid-November last year to prepare for the Spring Festival travel rush. Currently in use at some fast lanes, it has provided safe and efficient security checks to over 60,000 passengers.

A security staff member at the lane commented, "With conventional metal detectors, we would conduct secondary hand checks on each passenger, squatting and standing up over 1,000 times daily. Now, we directly perform targeted hand checks. Even if passengers forget to remove items from their pockets, it's immediately visible on the hand check station's display, offering both intuitiveness and accuracy. This has drastically shortened our hand check time and improved the passenger experience."

Many passengers are concerned about the safety of these scans. The equipment supplier assured that millimeter-wave is a safe electromagnetic wave suitable for use by the elderly, children, and pregnant women. Li, the head of Hikvision's millimeter-wave security inspection product team, explained, "Leveraging Hikvision's Guanlan large model, we've developed a dedicated large model for millimeter-wave body imaging detection. This not only ensures accurate and rapid measurement but also comprehensive detection. For instance, while traditional security gates detect metals only, millimeter-wave body imaging devices can accurately detect various metal and non-metal items, ensuring a safe and smooth Spring Festival travel rush with technological prowess."
