Xiamen Gaoqi International Airport, a key hub in China, faced the challenge of efficiently screening arriving passengers for COVID-19. To address this, Xiamen Customs collaborated with Nuctech to create P-VEMD, a multi-layered system using QR codes to streamline the health screening process. By integrating declaration information, health checks, and data backtracking, P-VEMD significantly reduces the time needed for passenger processing, improving efficiency and aiding in pandemic control. Since its implementation, P-VEMD has screened thousands of passengers, decreasing processing time from six hours to two, with health screenings taking as little as 90 seconds for asymptomatic individuals.
