Biometric technology has been installed for children's safety in six kindergartens in Nanjing, capital of east China's Jiangsu Province, according to the developer.
Parents must undergo facial and fingerprint recognition before picking up their children, said Mao Wenfeng, chairman of Jiangsu Sanyuan Educational Enterprise.
"Potential security problems exist as it is difficult for us to identify who is picking up the children," said Wang Fei, principal of Qixia District No. 1 Experimental Kindergarten in Nanjing. "Using biometric technology can help ensure children's safety, which is our priority."
The system allows storage of six people's biometric information per child, according to Mao.
