A system, a method, and a service that monitors the time a space is occupied. The time period for occupation of the space may be prepaid or the fees may accumulate while the space is occupied. The system detects when an occupant enters the space and starts a timer. The system further provides a user interface whereby a user may prepay for an allotted period of time or may accumulate time in the space and then be billed later. Identifying information about the occupant may be acquired by an imaging device. The imaging device may further poll the space to determine if and when the occupant departs from the space. Identifying information may also be acquired through a user interface in which a user may enter identifying information, such as a credit card, a license number, a VIN, a driver's license, etc. The fact that the space has been occupied, the identifying information, and any prepaid amounts are transmitted via a communication device to a control station. The control station may monitor events in the space such that when an occupant departs the space, the timer is reset. Alternatively, the control station may issue fees for use of the space, may issue penalties or even call for removal of the occupant from the space if occupation of the space exceeds the amount of time purchased or poses an abuse of the privilege of using the space.
