ABSTRACT:
An expired parking meter indicator with electronic components which detect the presence of a vehicle in the parking place. When a vehicle pulls into a parking place a signal is received by the parking meter which after a grace period emits a signal if no payment has been made. Furthermore, if a payment has been made and the vehicle remains in the parking place longer than the time received for the payment, a signal will also be generated. A parking control officer will be capable of receiving the signal and, thus, very efficiently citing parking violations.
