The phenomenon of missing children in school buses is a major concern for parents, schools, and transportation authorities. This can happen if kids get off at the wrong stop, split out from their groups or missed inside buses. By enabling real-time recording of the bus and its occupants, RFID technology significantly contributes to improving the safety of children when they are boarding a school bus. Children missing from school buses can be prevented with the use of RFID technology in a children’s bus safety system. The belongings of each child is given an RFID tag, and the bus is fitted with RFID readers. As a result, the system is able to accurately record children information every time they ride the bus, and notify their school staff and their families if they were missed inside the bus. Consequently, this system could save children lives and their physical and psychological health. Creating such systems has been made possible by the development of Internet of Things (IoT) technologies in addition to RFID.
