Abstract
In an access system and method for buses, a master card and respective slave cards for respective students are provided. The cards are read by a card reader to control access to the bus. A microprocessor and memory are provided together with an annunciator which determine whether a slave card annunciator code corresponds to an annunciator code on the master card, thus determining whether a respective student is boarding a bus which corresponds with his respective route.
