How your child scans on and off the bus depends on your district’s setup. Some school systems have bar code or RFID proximity readers on their buses and provide bar code cards or RFID cards/fobs that the students scan as they enter and exit the bus. Bus Pass can be used to put your student’s bar code on a smartphone, which can be then scanned by the bus’s bar code reader (see What Is Bus Pass?). An alternative to the bar code and RFID readers is the Synovia Solutions mobile data terminal (MDT), which enables the driver to select the names of the students as they board and exit the bus.
