The only “location tracking” involved is the short-range RFID technology that alerts PayByCar when your toll transponder is at a participating location. We use two-factor identification by texting your smartphone for confirmation. We don’t know where you came from before you got there or where you’re going after you drive away. The range of the RFID reader is limited to that specific location. PayByCar is a private company - your account with us is separate from your E-ZPass account.
