However, in this mixed industry, there are more and more problems, and parents are not at ease to put their children in institutions, because there have been many problems about custody institutions in the previous news. For example, management issues, diet issues, education issues, and the most important safety issues are all affecting parents' hearts all the time. As parents, they are always concerned about the safety of their children. Compared with others, safety comes first. So how to do security measures?

As the principal of trusteeship, we should take precautions before they happen and do a good job in children's safety education in combination with social problems. Secondly, as a school, we should also do a good job of parents, such as recognizing children's faces into the system, reassuring parents through the system, letting parents know their children's dynamics and picking up their children from school. All these need to be done by the custodian, and this can use the face recognition machine of the 365 custodian housekeeper to help send the child's punch-in photos to the parents' mobile phones, which can greatly enhance the image of the custodian and gain more trust from parents.
