A portable child safety seat system has three lightweight, easily transferable modular components. The system utilizes one or more pressure sensor switches configured to be placed under the cushion of a vehicle's infant seat or cushions of multiple infant seats to detect the presence of a child in that seat. Electrical lines connect the pressure sensor switch to an interface unit which contains a back-up electrical power source, i.e. a rechargeable battery. The interface unit is in turn connected by electrical lines to a controller component which has a plug section for receiving electricity and a display section to indicate the presence of the child in the infant seat.
