A server device for a car sharing system includes an image request device, a use permission request device, and an authentication information issue device. The image request device is configured to transmit an image request signal to the user terminal when a use request signal for the vehicle is received. The image request signal requires transmission of a user face image. The use permission request device is configured to transmit a use permission request signal including the user face image transmitted from the user terminal to the owner terminal. The authentication information issue device is configured to transmit predetermined authentication information to the user terminal when a use permission signal transmitted from the owner terminal in response to the use permission request signal is received. The predetermined authentication information is information for enabling an operation of the vehicle.
