Uniforms with GPS trackers keep kids under surveillance

Schools in Guizhou province and the Guangxi Zhuang autonomous region are using "smart uniforms" embedded with GPS trackers to make sure students do not skip class and to assure parents of their children's attendance and safety.

Nine schools in Guizhou and two in Guangxi have introduced the uniforms, which were developed by Guiyang-based tech firm Guizhou Guanyu Technology.

The company said in a statement that when students enter the school, the time and date is recorded along with a short video that parents can access via a mobile app.
