Electronic toll collection

Electronic toll collection (ETC), an adaptation of aircraft "identification friend or foe" technology, aims to eliminate the delay on toll roads. It is a technological implementation of a road pricing concept. It determines whether the cars passing are enrolled in the program, alerts enforcers for those that are not, and debits electronically the accounts of registered cars without their stopping, or even opening a window.
