Abstract:
1. A system for monitoring devices using near field communications (NFC) techniques, comprising: a plurality of host devices each incorporating an NFC device; an audio or visual alert device incorporated into each host device and operatively coupled to the associated NFC device; a detector device incorporating a detector NFC device; a monitor incorporated in the detector device and operatively coupled to the detector NFC device; an alert activator in each host device coupled to the associated NFC device and associated alert device that activates the associated alert device when at least one of the NFC devices in a host device moves out of communication range with at least one other NFC device in its associated host device or the detector NFC device in its associated detector device; a monitor activator in the detector device coupled to the detector NFC device and the monitor that activates the monitor when the at least one NFC device moves out of communication range with the at least one other NFC device or the detector NFC device; a home location device separate from the NFC devices incorporated in the host devices and the detector NFC device; and a disabler incorporated into each host device and operatively coupled to the associated NFC device that disables the associated NFC device when the associated NFC device is in communication with the home location device.
