Abstract: Contemplated systems and methods for automated and controlled vehicle access comprise a vehicle associated reader that informationally cooperates with a reservation system at which a user places a reservation. At the vehicle, the reader automatically retrieves a unique information code from the user (e.g., in form of an RFID signal) and is transferred to and compared with an entry in the reservation system. Upon validation, access is granted to already known users, most preferably in combination with a further validation step (e.g., via keypad). Users with previously unknown unique information code are issued a temporary code by the reservation system, and upon validation of the temporary code and automatic retrieval of the unique information code, the reservation database is updated such that the unique information code replaces the temporary code. Preferably, access is then granted upon further validation step.
