Abstract: Systems and devices for determining the presence of and managing objects contained within a container. The container includes at least one compartment that can house at least one object. In response to receiving a signal, the container is configured to transmit a signal regarding a determination of the presence of an object within a compartment. A first and second proximity sensor are used to cause a status check of the presence of an object within a compartment, such that the status check is initiated when the first and second proximity sensors are within a predetermined distance of each other. The determination of the presence of an object within a container may be transmitted to a connected wireless device. The connected wireless device may also remotely cause a status check of a compartment within a container.
