Asset tracking : ウィキペディア英語版 | Asset tracking Asset tracking refers to tracking the method of physical assets, either by scanning barcode labels attached to the assets or by using tags using GPS or RFID which broadcast their location. ==RFID==
'Passive' RFID tags broadcast their location but have limited transmission range (typically a few meters). Longer-range "smart tags" use 'active' RFID -where a radio transmitter is powered by a battery and can transmit up to 2000 meters (6,600 feet) in optimum conditions. RFID-based Asset Tracking requires an infrastructure to be put in place before the whereabouts of tags may be ascertained. An asset tracking system can record the location and usage of the assets and generate various reports.
