So to revisit this:
EZ Pass uses Mark IV/ Kapsch Trafficom with active transponders and most/all readers can accept only these transonders?
South Carolina uses EZ-Pass compatible equipment but is not linked?
Texas, Louisiana, Kansas, and Oklahoma use Transcore ATA1500 passive transponders and 6B stickers.
Florida used old ATA active transponders, ATA1500 passive, and 6B stickers. The old active ones are going to be terminated so that EZ-Pass can be programmed into tri-mode readers.
Georgia uses 6C stickers. But how does Florida read them and vice versa with only tri-mode readers in Florida.
Washington, Utah, and Colorado use 6C with no linkage, assuming these all have single mode readers.
Minnesota decided to be weird and use Telematics wireless.
What does Michigan use?
What does California use?
North Carolina uses Transcore transponders that can be read by EZ-Pass equipment and vice versal
