A technology and toll payment option that allows customers to use a pre-authorized toll account for payments at one or more toll facilities. The most widely-used of all ETC programs in the US is E-ZPass. In the US, ETC toll accounts provide a small radio-frequency (RF) transponder in a plastic box or on a sticker, to serve as the on-board unit that identifies the vehicle. Outside of the US, on-board units may also include other technological options, such as cellular communications or GPS application options such as on the European GNSS system. Sometimes accounts may be used for other commercial transactions such as parking, fuel payments, or fast food purchases.
