Mother and child bracelets

This is a product specifically designed to prevent children from getting lost. In fact, it is a pair of electronic bracelets that can be worn on the wrists of parents and children respectively. The two bracelets transmit information through wireless signals. Parents can set a rated distance in advance. When the child is within the rated distance, the bracelet will only display the time. However, if the child runs beyond the rated distance, the bracelet will alert the parent through vibration. At the same time, it will indicate the child's direction via a pointer on the bracelet, while the length of the pointer represents the distance.

Using such a product when going out can greatly reduce the chances of a child getting lost.
