Abstract
A lost article finding device, which can be used for, for example, finding keys and the like. The finding device has a element for automatically finding its location, such as a GPS device or other position detecting device. A transceiver receives requests from a remote location, and response to those requests. The requests may include periodic pings, which are simply sent to ensure that the device is responding to requests. The requests may also include specialized requests which specifically request the device to report its current location.
