A system and method that detects a presence of a child in a car seat comprises a pad and a receiver. The pad comprises a communication element, a unique identifier, a power source, a switch configured to adapt a power state from “off” to “on” by means of a child closing the switch disposed between the pad's power source and the pad's communication element. The receiver comprises an analysis element storing the unique identifier of at least one pad and a communication element in communication with at least one pad when the pad is powered “on”. The receiver determines a presence state of a child in the car seat when the receiver is in communication with the powered pad. The receiver determines the presence state when the receiver loses communication with the pad. The receiver further generates notifications with the determined child's presence state in the car seat.
