A global resource locator (GRL) device can be used to identify a missing asset. The GRL device can include a memory device and a processor. The processor can be coupled to the memory device. The processor can be configured to receive a communication from one or more of a plurality of GRL devices proximate the GRL device. The processor can be configured to store data received from the plurality of GRL devices on the memory device. The processor can be configured to determine that a missing GRL device of the plurality of GRL devices is missing based at least in part upon subsequent communication with a subset of the plurality of GRL devices. The processor can be configured to transmit a notification that the missing GRL device is missing to a non-GRL receiving device.
