I have an update on the E-Z PASS and silicone skin. My wife just drove around 600 miles from NYS to OBX which consists of a LOT of tolls. One no-stop lane in DE flashed something like "Tag Not Read" and the second time at the CBBT the gate didn't raise. The attendant said to take the cover off and when she did the gate popped right up. She said the cover interferes with the E-Z Pass and that the pass is meant to have the bottom face the scanner (like when it's stuck to the windshield in which case the cover would be fine). I don't know if it's the composition of the particular case but beware of both covering the E-Z Pass AND having it face away from the scanner. We have not had any other problems in the NE, just on this trip. I'm going to leave it where I showed it earlier for now, just without the cover. I can't wait for E-Z Pass to update their tech!
