Methods and systems are provided for determining the absence of a personal area network (PAN) device and for responsively presenting the time of the last detected presence of the PAN device. In an exemplary embodiment, a PAN device encounters a triggering event and responsively checks and determines that another PAN device is absent. Upon detecting the absence of the other PAN device (such as by detecting an absence of communication from the other PAN device), the exemplary PAN device presents via a user interface an indication of the time that it last detected presence of the other PAN device. By presenting the time of the last detected presence of the other PAN device, the user of the PAN device may be able to recall where he or she was at that time, which may help the user find the misplaced PAN device, hopefully at that location.
