Storyline: China has launched a new online arrival-card system to streamline entry procedures for international travelers and significantly improve the efficiency of border checks. The measure, introduced by the National Immigration Administration, went into effect on Thursday at major ports of entry in the country. At the Nanjing Lukou International Airport, the largest air hub in Jiangsu Province, dozens of inbound passengers aboard a flight from Ho Chi Minh City, Vietnam, were among the first to benefit from the new system, praising it for making the arrival process smoother and faster. "The new online system is much faster and more convenient. It's very good," said a traveler from Singapore. Currently, travel declaration now can be done through multiple channels before entry into China, including the official website, the government service platform, the 12367 app, WeChat and Alipay mini-programs. Travelers can complete information registration on their mobile phones by scanning a QR code . Meanwhile, traditional paper arrival cards remain available as an alternative option. "Compared with paper arrival cards, online filling is more convenient and efficient in information registration and entry declaration," said Chen Xiaohui, an officer from the first inspection team at the Nanjing Border Inspection Station.
