Abstract
A system and method for monitoring devices using near field communications (NFC) techniques is disclosed. A plurality of host devices each incorporates a NFC device. An audio or visual alert device is incorporated into each host device and is coupled to its associated NFC device. A detector has a detector NFC device. A monitor is incorporated in the detector and is coupled to the detector NFC device. An alert activator in each host device is coupled to the associated NFC device and associated alert device and activates the associated alert device when one of the host NFC devices moves out of communication range with another host NFC device. A monitor activator in the detector device coupled to the detector NFC device and the monitor activates the monitor when the one NFC device moves out of communication range with the other NFC device.
