A voucher in car rental is an electronic document issued by the broker to the renter.
It usually includes information about the rental, such as the pick-up time and location, the selected car, any requested extras, and so on.
At pick-up, the renter must present the voucher to confirm the booking and full payment.

Example sentence(s):
- You and all additional drivers must present a full valid original driving licence and the voucher when picking up the vehicle.
