The use of the latest type of personnel access management system, in order to build a "safety barrier" at the port of Shanghai World Expo, Wu Yan's border inspection agency adopted a series of scientific and technological means.

The use of personnel access management systems began on July 22, and a group of special "robots" - the latest personnel access management system was unveiled at the Wusong border for identification of port entry and exit personnel. The electronic access control system is placed on each outer wheel ladder and can automatically compare portraits and personal information with immigration personnel. If the information does not match, it will automatically alarm. Wu Jian’s frontier inspections enhanced the management and control capabilities of the ports of entry and exit during the Expo period through the enhancement of scientific and technological means, and reduced the work pressure on civilian police verification and verification. This not only drastically improved work efficiency, but also provided convenience for the majority of immigration personnel.
