Abstract: A system is disclosed for assessing roadway toll charges across a plurality of tolling agencies, for example a nation-wide system that allows use of a multi-protocol RFID tag that is recognized in a plurality of states having different tag protocols in their electronic tolling systems. In an embodiment, each tolling agency sets aside numbers associated with the national system. Where a tag is read that is not identified as part of the national system, the local agency processes the tag transaction. There a tag is read that is identified as part of the national system, regardless of which tolling agency reads it, the transaction information is sent to a national customer service center for processing.

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.
