At the Yunnan border of China, X-ray vehicle scanning systems are widely used for security checks.

The Yunnan border port is an important channel connecting China and Southeast Asian countries, with a large number of vehicles and goods entering and exiting every day. In order to ensure border security, the local government has taken multiple measures, one of which is the introduction of an X-ray vehicle scanning system. The system is installed at border checkpoints and can quickly and accurately scan passing vehicles. Through the scanning of this system, security personnel can promptly detect hidden dangerous items in vehicles, such as drugs, weapons, etc. If suspicious items are found, the system will automatically alarm and security personnel will conduct further checks.

Once, a truck loaded with goods was inspected by an X-ray vehicle scanning system, and the system issued an alarm. The security personnel immediately guided the truck aside for further inspection. They carefully scanned the truck using handheld devices and found a suspicious package. After careful inspection, the package contained a large amount of drugs.
