Florida's Turnpike & Georgia ExpressLanes to join E-ZPass Network

The problem with interop is existing legacy equipment. The largest installed base is clearly 915Mhz E-ZPass IAG protocol active tags and readers using 25+ year old technology. The rest of the industry has since standardized on much newer passive RFID stickers speaking ISO 6C. Years ago, the IAG should have pushed members to install multi-protocol readers as equipment failed or in new construction.

Same goes with the tags. As the batteries die in the old ones, issue new tags like the NC Quickpass hard case transponders that talk both IAG and 6C. Eventually you'll have everything transitioned to 6C and one can retire the old active 915Mhz IAG tag readers. You can speed adoption by promoting the new tags as being interoperable with other tolling systems as well.
