This morning, the opening ceremony of the International Police Equipment Expo is being watched.

Standing on the pedals, your feet can detect whether there are explosive devices or dangerous articles in your shoes in only 2.6 seconds.

This morning, reporters at the fourth China International Police Equipment Exhibition held at the Beijing exhibition hall learned that the safety tester for shoes will be applied to Olympic security, and the relevant security departments have ordered more than 10 units, which will be used for the Olympic venues and key officials.

The company responsible for developing the shoe safety tester said that the tester made up for the defects that the common inspection doors could not check whether the shoes contained dangerous articles, and also avoided the trouble of letting the inspected objects take off their shoes. The safety of the shoes could be detected through the display screen.

The shoe safety tester is divided into two parts: the pedals and the display. There are two small feet on the display screen. If the shoes of the inspectors are in danger, the normal green feet will turn red, and the display will send out the alarm of "Di".

At the same time, three areas of red, yellow and green show the general varieties of suspicious items in shoes, such as ordinary steel in shoes or non-ferrous metals in dangerous goods.
