Abstract
An RFID tag is disclosed for use in roadway tolling systems having specially designated lanes for high occupancy vehicles, wherein more favorable toll rates are allotted to vehicles with more than one occupant. In an embodiment, the tag has a selection switch for connecting one of a plurality of ASICs to an antenna. Each ASIC is programmed to transmit a different message, wherein the message conveys information regarding the occupancy level of the vehicle. There is also information in the ASICs that is common to them for the tag
